Life extension of existing nukes.

Is nuclear fission going to make a comeback and plug the gap in our energy needs? Will nuclear fusion ever become energetically viable?

Wonderful news. That will give us time to build plenty more renewables, and implement radical energy saving. After the seven years we can abandon nuclear and fossil fuels :D.

Is there a flaw in my argument?

SizewellB?????
That's the only PWR in operation in the UK (when it's not down for maintenance) and only became operational in 1995. It's decommission date is 2035
Don't you mean Sizewell A - oh, hang on a mo, that's shut....

Hinkley Point B in Somerset, and Hunterston B in North Ayrshire, are now expected to remain operational until 2023. Both had been due to cease generation in 2016.
Here's a chart I produced some five years ago:

Heysham and Hartlepool have subsequently had their lifes extended by two years and now Hinkley Point B and Hunterston B get an extra seven years.

What's interesting is that Hinkley Point B and Hunterston B are the oldest AGR by some margin (coming on line in '76) and have already had an extension to 2016. The announcement today is a 2nd extension. The other point to note is that reactors at these two sites are operating at only 70-80% capacity

Do we know what implications this has, if any? Were the initial lifetimes just guesses, so that a change to them isn't particularly significant? Or is it truly a "get back on the pitch, even if you can only stand in the way" type situation?

:oops: I think I may have meant Hunterston B. It was on the radio this morning just before I woke up. Might just have been a nightmare.

Nope, it's true: http://www.bbc.co.uk/news/business-20590172

Dungeness B is shut down for a planned outage and is not expected to resume operation until the Autumn, this is a longer planned outage than most, and AFAIK is for examination of the graphite blocks that form the core.
As these reactors are of the same design as those at Hunterston B, and have also been life extended, I perceive some risk of excessive numbers of cracked graphite blocks being found during this outage.

Any significant delay in re-starting might lead to winter power shortages, especially if anything else goes wrong.
