Tell me something, why do you suggest that storing the spent fuel rods is a bigger problem than the *tons* of radioactive material spewed forth by burning coal? Umm, because it's all in one place. And unless you keep it cool, it will get really really hot and do bad things. Are you just trolling, or doyou really not know that? If you do, than you can answer the following question: What does Entergy do when it can no longer store spent fuel on site at their Indian Point reactors? Does it a) ship the fuel to a licensed disposal site, out of state, b) put it in the local trash for the garbage men to pick up, c) put it in with the rest of the spend fuel from IP numbers 1, 2, and 3, in teh spent fuel pool, d) say, 'no more room for spent fuel, have to shut down the site and start decommisioning. Sanity check time. a) is no good, there *is* no such fairyland. If there was, they'd use it in a heartbeat. b) the local trash guys would pick up anything. So don't think about that because they *would* pick it up. c) no good. The spent fuel pool (actually the old IP number one reactor site) is now full. d) also no good. It would cost too much to do that, and that would cut into the profits. The plant makes money for its owners when it *runs*. There is no profit in an idle plant, and worse, decomissioning a plant that old is going to cost way more than they say. And they know that. The last issue has been discussed here in this thread already.

Jim,
Any endeavor of man has benefits and costs. The United States has been collecting a tax on all of the power generated at all of this countries nuclear power plants for years promising to build a repository for the waste. As I remember it, if you were to stack all of the spent fuel rods in one place it would fit inside an average high school gymnasium. This is not a whole lot of stuff to store in such a way as to protect the public. The longer we delay Yucca Mountain, the longer we delay the benefits of building more nuclear power plants. Now you seem to have almost a religious belief that nuclear power is bad. I however do not hold such a belief. I feel that the advantages gained from nuclear power far outweigh the risks and the costs. Consider the costs of the alternatives. Coal is very polluting. Even so called "clean burning" coal dumps tons of radioactive material and other nasty stuff into the environment. Natural gas is fairly clean, but the supply is limited and there is still the CO2 released when the gas is burned. Hydroelectric is good, but how many more dams can we build? Solar and wind are just too inefficient to supply the quantity of power we need when we need it. Oil is not cheap nor can we have a reliable supply. Sooner or later our automobiles will be run on hydrogen, but it takes energy to make the stuff. Nuclear fusion would be great but is no where near commercial viability. Fission we got down. We can produce massive amounts of electricity on the cheap. Sure this produces spent rods that need to be dealt with, but that is not an insurmountable problem. Cheap power is good. With cheap power the price of steel drops, the price of concrete drops, and the quality of life improves. Burning less fossil fuel would give us cleaner air and water. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff.

Jim, Any endeavor of man has benefits and costs. The United States has been collecting a tax on all of the power generated at all of this countries nuclear power plants for years promising to build a repository for the waste. Hmm. So now it's the government's responisibility? If this were a discussion about education, or welfare, or product liability, the term "nanny state" would be thrust into play at this point. Why shouldn't Entergy Co. be required to run its buisiness *without* government assurances that they will be bailed out in the end? And by 'bailed out' I mean, 'the nanny state will step in and buy all the fuel rods and the decrepit plant, for one dollar, at the end if it's lifetime.' Because that's the kind of subsidy that apparently is needed to make the nuclear power business a paying proposition. As I remember it, if you were to stack all of the spent fuel rods in one place it would fit inside an average high school gymnasium. This is not a whole lot of stuff to store in such a way as to protect the public. Yep, and if you removed all the space from inside the atoms in the fuel rod assemblies, you could fit them all inside a teacup. My point being, you *can't* stack them in a swimming pool, and you know that. Saying so is deceptive. If they *could* do that, they would. Trust me. They're having enought trouble stacking *one* plant's spent fuel in one swimming pool right now, in Buchannan, NY. The pool is full and for them to keep running the plan they've got to start taking the older stuff out so the hot stuff can go in. Otherwise Entergy corp. has to shut the plant down. The longer we delay Yucca Mountain, the longer we delay the benefits of building more nuclear power plants. Now you seem to have almost a religious belief that nuclear power is bad. NO! I don't. You mis-state my comments sir. They are factual and true. "Bad" or 'good' in this case is not of interest. The question is, can a company make money doing this, amortized over the lifetime of the plant. To put it another way, it's not fair to stockholders if a company sticks all of it liabilies in one box, and then sticks that box under the bed to cover it up. Then they go and tout how much profit they make and how good a deal their stock represents. There's been a lot of that going on lately, too. With other energy companies - it seems to run with the business. Unless the *full* costs are laid on the table, any discussion of cost/benefit is a lie. Plain and simple. And it's in the industries interests to de-emphasize the costs. I however do not hold such a belief. I feel that the advantages gained from nuclear power far outweigh the risks and the costs. OK, but be aware that the folks who are giving you the balance sheets are lying, to some degree or another. Oh, they won't *say* 'we're lying.' They might say, it costs $36B to do a decomissioning one day, then the next day, hey, fire sale! it costs only seven. At the end they have a vested interest in understating their liabilies because they are for-profit companies and it lets them get better ROI. And this includes the spent fuel issue. Consider the costs of the alternatives. No. This part of the discussion isn't about how bad something else is. It's about the real cost/benfit analysis of nuclear power. Let's stay focussed. Cheap power is good. Agree! Get private companies out of the business, so the ROI issue goes away, *or* force them to state the real costs of long term nuclear generation, without goobermint subsidy, *or* be prepared for the public to have to pick up the tab when the rent comes due. I suggest you contact entergy corp and request that a few casks be delivered to your house, straight away. They'd be happy do comply.

I think I would disagree with your pejoritive comment about physicists. Accurate my friend. Trust me on this. I work with them 365 days a year. There's a vast number of them who I would not trust with a stone hammer or a sharp stick. Most of those are theorists and they would be the first to tell you this is true. They have no illusions that their specialized knowledge, deep and profound though it is, allows them to circumvent the rules of engineering. There are also a select few experimentalists who are truly dangerous because they *think* they know what they are doing. Where I work, there's a reason why the machinists and modelmakers are afforded such respect: they often understand engineering and materials better than the scientists they work for. Science has vastly improved our lives, and I do not believe that this trend will change. My how your mind hops about. Did somebody *say* that science was a 'bad thing?' Did I make a statement such as "boy that sience stuff sure is bad, it's gonna kill us. We had better go back to flint arrowheads, and stick some wooden shoes in the gears?" You are mistaking 'science' for the economics and engineering in the nuclear power industry. Two very, very different things. Sure, any undergraduate physics major could tell you, the fuel rods are made of thus and such material, with this melting point, and after they are removed from service, they generate such and such and amount of heat, for this amount of time. And will have to be stored to keep their temperature below this level. That's pretty much it. Everything after that is involved in either a) keeping down the costs or b) PR to tell folks 'it's really not that bad.' Because given the political situation the stuff's *not* *going* to *move* anywhere. Why don't you apply your manifold expertise to this, to explaining how this *can* change? And while you are at it, explain how they are going to move the fuel around and store it, so the taxpayer does not have to foot the bill? Otherwise it's just another example of corporate welfare that is so often discussed in this ng.

And still should be as far as I'm concerned, I'm sure it won't be long and my house will be shook again. Have you ever felt them?

I recall seeing footage of the back of the simi leaking. Epoxy ! LOL Sure it was just low level waist , but showed nothing on the Geiger counter? Why truck it all the way across the country if it was just water? Now we are running out of water and they ( ahhh GGG the Nev. gov't) are setting up to extract water from around the NTS.

LOL I wonder if they told the people in Russia that they would be dead within a week of going into that place. Our scientists warned them of the face that they had a **** poor design. The Soviets ignored the warning. Not that , the people who went in the plant to help somehow to contain it, did they ( the Russian gov't) tell them they are most likely to die before their pay check?

I can just imagine ! The plants are built like a nuke bomb shelter with what 10' concrete and rebar all over? That must cost some bucks and then tear it down while glowing and then truck it to NV. Plus all the liquid and dirt from the site. Sounds really ****ing expensive to me. But we are to believe its less than $.03 a KWH. Yeah, right. Granted we need electricity , maybe design them to be left in place , hell I don't know. Make bigger pools and keep it there. Read one of these pack rat threads, its a major pain to move all the stuff little alone hot. I bet they are still scratching their heads over what to do with 3 mile island and that was ahhh 25 yrs. ago. BTW , from what I've seen on TV they (TMI) dumped alot of glowing stuff and would not tell the people about it. Wish I could find that political cartoon about trust us. It had about 5 examples of how the gov't lies about the subject. Kinda like giving poor blacks syphilis and letting it run its course. Don't these people ( do I have to spell it out?) swear an oath to protect and serve ect. ect... to the citizens of the US? Frankly I don't think I'm mis anything. Since your so smart , I have a question. How much radiation is in lead from say a hospital. None? A lot? Some, elaborate. How does it stop it and where does it go? How many nuke subs are sitting on the ocean floor ? Got info on space nukes? Have they done it? Ya know them and explosions not power plants. |

Mining and railroad companies had/have a great deal of influence so they get rules and legislation passed that favor them - to the point of being nearly a public subsidy. The nuclear industry is quite analogous to your other examples, they take in quite a bit of public money, with fuel issues. Do nuclear plants actually have to purchase the fuel they burn?

So it has a nice containment building around it, and so on. I think it's cheaper to pull the fuel rods out and store them aboveground, if it's engineered properly. Also if they're not relying on water for cooling, then it can't leak out and cause a problem. I suspect the guys running that show could not even manage to build swimming pool that was watertight. There was quite a flap at Brookhaven Labs about three years ago, because the cooling water tank (swimming pool) kept requiring a lot of make-up water. Yep, the hot water was leaching into the ground. Hot, meaning it had a bit more tritium in it than it should have. I think the site director ultimately lost his position over that event.

No, they're supposed to serve and protect the industries that donate to their campaigns. How many nuke subs are sitting on the ocean floor ? Oh my. Is *that* how the military (well, the soviets anway) decomissioned their used reactors? Say it's not so! Got info on space nukes? Have they done it? Sure. But those are pretty innocuous compared with a submarine reactor hulk. Smaller, less material, simpler. Those are thermoelectric generators. Basically some decaying isotope that gets hot, and runs a series of large thermocouples to generate small amounts (100 watts IIRC) of electricity for on-board instrumentation.

Sounds to me like there was no problem. I also note that this was in December. Perhaps the water didn't originate from the plant in Ohio, perhaps it was snow or rain that had fallen on the cargo. The term low level waste is rather deceiving. This could mean a set of coveralls the guy driving the forklift was wearing when he carried the hot fuel rods to the cooling ponds, or the dirt he drove the forklift over. Now we are running out of water and they ( ahhh GGG the Nev. gov't) are setting up to extract water from around the NTS. Bet they say there is nothing wrong with the water and never will be, do you believe that? LOL Well one thing about radiation is it is easy to test for. Not that , the people who went in the plant to help somehow to contain it, did they ( the Russian gov't) tell them they are most likely to die before their pay check? I bet NO. Perhaps they were bona fide heros. Perhaps they were worried about what would happen if the sacrifice was not made. I'm not informed at all. I can just imagine ! The plants are built like a nuke bomb shelter with what 10' concrete and rebar all over? That must cost some bucks and then tear it down while glowing and then truck it to NV. Plus all the liquid and dirt from the site. Sounds really ****ing expensive to me. But we are to believe its less than $.03 a KWH. Yeah, right. Currently 20% of the electricity generated in the US comes form just over 100 nuclear power plants. Do the math. Granted we need electricity , maybe design them to be left in place , hell I don't know. Make bigger pools and keep it there. Read one of these pack rat threads, its a major pain to move all the stuff little alone hot. I bet they are still scratching their heads over what to do with 3 mile island and that was ahhh 25 yrs. ago. BTW , from what I've seen on TV they (TMI) dumped alot of glowing stuff and would not tell the people about it. Be careful about what you see on TV. Often the more controversy the producers can create the better the ratings. This is often at the expense of the truth. If TMI had "dumped a lot of hot stuff", it would be detctable. So where is it? Wish I could find that political cartoon about trust us. It had about 5 examples of how the gov't lies about the subject. Kinda like giving poor blacks syphilis and letting it run its course. Don't these people ( do I have to spell it out?) swear an oath to protect and serve ect. ect... to the citizens of the US? Frankly I don't think I'm mis anything. Since your so smart , I have a question. How much radiation is in lead from say a hospital. None? A lot? Some, elaborate. How does it stop it and where does it go? I am not sure, but I bet if you asked the question on alt.energy.nuclear I bet someone there could explain it. One thing I did have personal experience with was a large lead lined box that I helped move from an industrial plant to the scrap yard. The box was used for some sort of industrial process involving radiation. Before the scrap yard accepted it, they came out to the truck with a geiger counter, adjusted it to get a background reading and when they stuck the probe into the box the needle fell to zero. How many nuke subs are sitting on the ocean floor ? I am not sure. But there doesn't seem to be a lot of sick US sailors that lived inside of those small confined spaces, the Russian sailors I am not to sure about. IIRC water is a good radiation shield, perhaps this might explain why this is not an issue. Got info on space nukes? Have they done it? Ya know them and explosions not power plants. I have no specific information, but there is a whole lot more radiation in space than there is at sea level just like there is a lot more in Denver than in Seattle. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff. |

This is not a whole lot of stuff to store in such a way as to protect the public. All the spent fuel used in all commercial nuclear plants since the beginning of the nuclear age would fit on a football field, making a pile with a depth of 3 feet (in other words, about 5,000 cubic yards). As Jim notes below, actually doing that wouldn't be a very good idea, due to criticality issues. In reality you'd need to increase the volume about 36 times (in air) in order to avoid overheating. But you're right in essence, it isn't a huge amount of material. In fact it is miniscule compared to the wastes produced by any other power generating method. More importantly, most of it isn't "spent". Only about 3% of the fissile material in a "spent" rod has fissioned. By using reprocessing, almost all of the remaining fissile material could be recovered and reused (and if breeder technology were used, more fissile material would be recovered than was originally present in the rods). That means the amount of *real* high level waste, stuff with no commercial value, is much smaller than the already tiny amounts we're talking about. Yep, and if you removed all the space from inside the atoms in the fuel rod assemblies, you could fit them all inside a teacup. My point being, you *can't* stack them in a swimming pool, and you know that. Saying so is deceptive. If they *could* do that, they would. Trust me. They're having enought trouble stacking *one* plant's spent fuel in one swimming pool right now, in Buchannan, NY. The pool is full and for them to keep running the plan they've got to start taking the older stuff out so the hot stuff can go in. Correct, and they've already paid the federal government $22.5 billion dollars to do just that. The problem is, the federal government won't live up to their end of the bargain. The feds took the money, but they won't deliver the service. To add insult to injury, the NRC won't allow the utilities to dispose of the spent fuel in any other way. If the federal government didn't prohibit it, the utilities could simply build other cooling pools following the Safstor protocols, or sell the fuel rods to reprocessors in France, Japan, or Korea, or start up a reprocessing facility of their own in the US.

Federal law requires them to turn the spent fuel rods over to the US government for disposal, the government has already been paid to accept them, but the government won't obey its own laws, and is refusing to take the rods.

We have a very good handle on the methodologies required, and on their actual costs. The trust fund was designed to cover costs higher than actual practice has shown us to be realistic. In other words, it has a lot more money in it than is strictly necessary to safely accomplish decommissioning and high level waste disposal for all existing US plants. Gary |

But Gary, did you ever believe in a government "trust" fund? Seems that the
guv types just see that a source of more money, with the actual payout to be funded by future taxation. Ask about the Highway Trust Fund, you get blank stares from our politicians.

Yes, it is relatively easy to separate Plutonium from the rods. That's why the government won't allow industry to do it. In other words, the government has an irrational fear of domestic nuclear proliferation. Never mind that *other countries* do it routinely, our government has seen fit to deny the technology to our *domestic* nuclear power industry. This policy makes no sense at all, of course, but it is all too typical of the way government operates. Gary |

Given that the price of white elephants always rises, and that no one can know the eventual total fund contribution from the plants without knowing how long they'll last, there's no way to put a number on the fund's shortfall.... except to say that it would have been mind boggling. This tempest in a teapot is all purely political, of course. There is no valid scientific, engineering, or financial reason why nuclear waste disposal should be a major issue. It's science and finances that have doomed Yucca. They tried to trump both with politics, but it didn't work. The $6 billion spent so far has only bought a couple decades of delay in having to face up to the reality of waste storage. Wayne |

Someone somewhere probably passed a law that says only the government can do that and they won't do it because the general public is so ill informed that any move that brings nookular stuff into the spotlight will cause outrage and cost votes. Likewise, I wonder what would happen if some little country out there were to build and run breeder reactors to make plutonium and then make power plants that ran on the plutonium. It would go a long way to break the plutonium == bomb mindset and intorduce the idea that all this "waste" isn't, yet. -- Joe -- Joseph M.

Past experience with decommissioning commercial reactors (100 worldwide since 1954) has shown us that it costs roughly $200 per kWe (2004 dollars) to decommission and dispose of the hot parts of the plant. For the typical 1000 MWe commercial power reactor, that comes to $200 million per plant, leaving $25 million per plant to spare at the funding level which existed in 1999. It is 5 years later now, and the fund has grown by another $500 million since then. Note, the fund was not designed to pay for demolition of the conventional parts of plants.

Sorry, I couldn't afford to stay in school and got pulled out of physics for more important prerequisites like government and psychology. Lead is a stable end point of nuclear decay. That's how all lead that now exists was formed. There are a number of isotopes of lead. All but 3 of them have *very* short half lives, ie they *very* rapidly decay to a stable isotope of lead. So for all intents and purposes, any lead you encounter that's been out of a neutron flux for more than a few days will be stable, ie not itself radioactive. Lead *can* be contaminated by radioactive materials with which it has had contact (in the same way your shoes become dirty when you walk across a muddy field). Unless they've been melted together, however, any contamination would only be on the surface of the piece of lead. As to why lead blocks radiation, it is a very dense material. Gamma radiation is just a higher frequency of light (as are X-rays), so a sufficient thickness of any material can block it. Lead just happens to be particularly dense, so it doesn't take as thick a piece of lead to block it as it would dirt, or water, or brick. (A foot of lead is roughly equivalent to 12 feet of water, 8 feet of dirt, or about 5 feet of brick.) Alpha is just a rapidly moving helium nucleus, and lead will stop that same as it would stop a thrown ball (in fact even your skin would stop alpha). Beta is just a rapidly moving electron, lead stops that too. In all cases, the kinetic energy of the radiation is converted to thermal energy (heat) in the material blocking it. Since gamma is pure electromagnetic energy, you could say it is absorbed. Since beta is a rapidly moving electron, it just becomes another thermal electron in the lead after it is slowed down. Alpha is a rapidly moving helium nucleus, and after it slows, it grabs any handy loose thermal electrons to make ordinary inert helium gas. Now there's one other form of radiation, that's a neutron flux. Fissioning atoms often energetically eject a neutron during fission (not all species do, but some, in particular the ones we use as nuclear fuels, do). If this neutron strikes the nucleus of another atomic species, it *can* (number of factors involved) transmute that atomic species into a different isotope (same number of protons, different number of neutrons). The latter isotope *may* be radioactive (again several factors are involved), in other words it may also be unstable. The fact that certain fission reactions produce a neutron flux, and that flux can then transmute certain other fissionable materials in such a way that they too immediately fission, is why we can have a nuclear chain reaction in the first place. Lead isn't very interesting in this regard because the unstable isotopes have such extremely short half lives, and their decay doesn't produce a neutron flux. In other words, any transmuted lead *very quickly* decays (via beta decay) to ordinary stable lead. Other elements, however, can be *activated* by a neutron flux, and converted to longer lived radioactive isotopes. One of particular concern is cobalt, another is strontium. You really don't want to expose either to a neutron flux, and if you do, you'll need to isolate the product from the environment for up to 10,000 years. Fortunately, nuclear engineers know this, so for the most part they don't design reactors which contain atomic species which can be transmuted by the neutron flux inside the reactor into particularly hazardous species. (OTOH, bomb makers may choose to use some of these nasties on purpose to enhance the fallout effects of the bomb.) The main things inside a reactor, other than the fuel, are water and the steel housing of the reactor. Steel is mostly iron, and iron is at the bottom of the curve of binding energy, so all of its isotopes are stable. Some of the alloying elements, and the carbon, in steel *can* become activated, though. So you have to treat the steel reactor vessel (and primary cooling loop piping) as a radioactive material which must be properly disposed. (It isn't intensely radioactive, but you wouldn't want to reuse the scrap for non-nuclear purposes.) This is the one part of a decommissioned nuclear reactor you might want to bury. One approved method of doing that is to simply fill the containment building housing the reactor vessel with concrete after the reactor has been defueled. That's what was done to the Fermi plant in Detroit. By the time the concrete erodes away, the radioactivity of the activation products trapped in the steel will have decayed to a negligible level. Most other nuclear wastes (not counting military wastes or nuclear medicine wastes, which present special problems because they are designed to interact with biological systems) are *low level* wastes. Our regulation of this is so strict that the concrete blocks that make up the foundation of your house are more radioactive. Yet, unlike those concrete blocks, we are required to perpetually isolate low level nuclear waste from the environment. For the most part, this is nonsense political science, but to the extent it isn't, simply stuffing this waste into the abandoned tunnels of the original uranium mines would be sufficient disposal, since that natural ore was *at least* as radioactive, and had been so for millions of years. No need for an elaborately engineered thing like Yucca Mtn. Gary |

... Lead isn't very interesting in this regard because the unstable isotopes have such extremely short half lives... Now, does this mean lead with extra neutrons, or lead having been transmuted to bismuth? In other words, any transmuted lead *very quickly* decays (via beta decay) to ordinary stable lead. By conservation of charge, a neutron splits into an electron and proton as I recall. So you'd have bismuth with one less neutron than the lead before. After that... it could drop an alpha to thallium (which I've never heard of before), or um another neutron I suppose. Or some chunky gamma ray? For the most part, this is nonsense political science, but to the extent it isn't, simply stuffing this waste into the abandoned tunnels of the original uranium mines would be sufficient disposal, since that natural ore was *at least* as radioactive, and had been so for millions of years. No need for an elaborately engineered thing like Yucca Mtn. Except for the fact that now you have a whole bunch of other elements in it that'll leech out and whatnot. Which reminds me, could you take U235 or Pu239, fission the hell out of it and chemically seperate the products into usefulness? Would they be too radioactive to be useful? Would a few days/years/centuries/millenia clean that up and retain the uh chemical usefulness?

We don't have to bother with caves, since we have enough barren desert area to spare to simply store the containers in the open. Yeah, but now you're back to two of the biggest problems with Yucca - transporting the waste, and inflicting it on others. The real risk is almost irrelevant, because any policy that includes those two problems is bound to be bogged down forever in political wrangling. There are two main reasons people don't want to store waste in the open next to the plants - they can't wait to get rid of it (and they really don't care where it goes so long as it's somewhere else), and cost. How do you even predict the cost of monitoring, potential cask replacement decades down the road, etc.? All that said, it's time for folks who are favor of having nuke power, to take responsibility for their waste. That means on-site storage, for a very long time. Wayne |

In that case, 22.5 comes under the heading of 'nice try, thanks for playing.' So Jim, why should it cost so much? When a plant is up and running, employees are walking around and they don't seem to be dropping like canaries in a mine, so I would assume that most of the place can be disposed of without much expense over what a regular building could be disposed of. Of the parts that are the glow in the dark nasties, it would seem to me that these can be disassembled and disposed of with reasonable care without astronomical expenditure. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff. |

So Jim, why should it cost so much? Now that question I honestly cannot answer. Maybe you could look at Shoreham as an example. That plant wasn't even supposed to run, but the unions forced the issue to have it run at full power for a week, so that they could then rake in big money to dismantle it. I cannot answer 'why' questions, only 'how' ones. Consider how much profit a plant makes over its lifetime. I would suspect the dismantling costs to amount to maybe one or five percent of the total profit generated over the plant's lifetime. How much money did indian points one, two and three create for their owners over their lifetime? I don't know that number. It would be interesting to find it out.

If anyone has flown over this state they would get the idea. I just love the stop building thing cause the desert tortoise won't have anywhere to live. Or the very expensive environmental impact studies for solar energy on the NTS when they already nuked the poor turtles. |
