I wonder who picks up the £700m decommission bill.
And if it includes dealing with the nuclear waste for however long it takes?

Why does it need to be closed down anyway? It would be cheaper to do whatever is necessary to keep it going.

Being the last reactor of its kind in the world, it has simply run out of fuel as it is not manufactured any more. It's already had years of life extensions.

The 5 extra years running at lets say 416 MW (10,000 MWhr/day) and
5p/kWHr
is £500,000/day. For 60 months less 3 months for two statutory
outages etc so 1750 ish days gives £875 million.

The operating costs have to come from some where but it looks to me
as if the bulk of that 700 million is in the bank already.

The Magnox company does, most of the revenue from the electricity is
going into that fund.

And if it includes dealing with the nuclear waste for however long

Of course its does.

Why does it need to be closed down anyway? It would be cheaper to do
whatever is necessary to keep it going.

It wouldn't. It was burning up the last of the special fuel. Its an old
reactor..

What do you mean?

There is no issue. The plant is closing because its at the end of its life.

For the guardian, its unusual. They are simply reporting the facts.

If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
time as the State can shield the people from the political, economic
and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

Video of the shutdown here. Interesting they chose to do it by hitting
the emergency trip button, unless that was just for show.

It's run out of fuel (they've been using part-spent fuel from a shut-
down reactor to keep it going), and the boilers are leaking.

That's been on the cards for some time, the worrying thing is the AGRs
won't be granted extensions and I think the last one will be ordered
to stop by 2023.

Found it on Youtube yesterday. Pathetic, mute apart from some silly
music, random shots of people moving switches and a few flashing
lights. No explantion, even a dumbed down one as to the procedure or
any "human interest" on how the staff felt.

We shall see. We are still making fuel for them, though. The Magnox fuel
plant was closed some time ago.

Yes we will have some interesting times ahead, mind I may well have
ceased to worry by then.

It's not the fuel but more similar to a sort of fatigue effect which
becomes inevitable after slowing down sufficient neutrons, it's not
possible to renew the core. EDF hope to run them for as long as
possible because there's not a cat in hells chance of replacements
coming on stream in time.

Much simpler than going through a manual shut-down sequence. In fact the
operators should not have to touch anything for half an hour after any
sort of incident which causes a trip.

They are getting near end of life. Neutron bombardment makes the steel
go brittle and the concrete crumbly. They have done better than they
were designed to.

https://en.wikipedia.org/wiki/Radiation_damage

Is a good read

And in fact radiation damage - potential - is one if the reasons the
Finnish reactor is overbudget and behind schedule. The local contractors
didnt understand or take regard for the need for very specialised
concretes and steels. So they didn't build it correctly and it had to be
ripped up and started again, in a limited way.

Once we build more reactors more often, that sort of problem becomes a
non issue. Also SMRs should help as the concrete and steel is largely
factory built there, so QC will be easier.

+1.
I am pinning my hopes on bog standard Jap EBWR designs at wylfa, and SMRs.

AFAIK neutron damage is not particularly an issue with AGRs (although it
is with some of the PWRs, where the mid-region of the reactor pressure
vessel sees high neutron doses). The trouble with AGRs is that they are
*really complicated* so that many different parts of the plant are
subjected to different ageing processes. This includes the graphite
cores, but also other steel structures.
