OT - Anyone watching the Japanesee Nuke situtation closely?
They are trying to run a new power line to the plant to power the
pumps. What I do not understand is why not bring in a generator, is there not a generator anywhere in Japan or the world for that matter that cannot power at least one pump? One big ass generator and a Chinook helo to put it in place. Or abunch of gen sets. CH-47D Chinook = 26,000 pound lift capacity. What am I missing? |

It'd be safer to sacrifice (let's face it) one or two people to connect the far end of the cable to the pump than to sacrifice several more people on a daily basis to fuel and maintain the generator in the middle of a radiation gale. I *guess* that particle concentration falls as the square of distance, so keeping people far away is a good idea. --Winston |

A long cable would still be necessary. --Winston |

CH47 can't lift the kind of generators they had on site, probably in tha class of 6000 Hp each, and they had more than a few. I got a tour of our local Nuke plant years ago, just a single unit, I think the primary coolant pumps were 1000 Hp each, and there were 4 of them. Anyway, they had 6 Diesel generators, and each was at least the size of a locomotive engine, about 20 feet long and 12 or 16 cylinders. They HAVE been running generators on some of the reactor units for days now, but it seems that some of the pump motors or something were wrecked by the tsunami. They are replacing those now. Jon |

Jon Yeah..that little detail that all the electrical stuff was submerged with salt water. Anyone who has dealt with flooded electrical systems (and especially with salt water) can tell you the nightmare these poor guys are dealing with. The management and politicians should have to be working along side those who are trying to fix this. TMT |

Engine starting battery in that size, probably requires
about a two year back order from NAPA? And, try to find people who are trained to do the lube oil and filter.

Bring in tankers of distilled water to wash off all the pump motors?- Hide quoted text - - Show quoted text - It's not what is on the outside, it's what is inside the pump motors..and switch boxes...and wiring trays...and breakers...and...well you get the idea. Meanwhile being exposed to high levels of radiation. I predict that they will run out of people to do the work...the experienced ones are likely close to their lifetime dose of radiation. Maybe they can import cheap American conservatives to do the dirty work.... TMT |

Wes Wes, I was surprised and I thought the odd looking helicopter, the Sikorsky CH-54, was the heaviest lift and Soviet but turns out to be nowhere near the heaviest lift, that featured in a Hollywood movie lifting a bus IIRC. Must have been embarrassing for the Chinook to be picked up by the Soviet MI-26 but what the hell Sikorsky was Russian to start with. |
