The Dungeness B reactor in Kent has been given another 10 years to operate, extending it's working life to 2018. [ News article. ]

Could we expect to see more of this?
How safe is it?

Yes, GD.

Load the waste into rockets and as Pink Floyd sang, "set the controls for the heart of the sun". Very Happy

That's interesting. Some plants have already been extended (and represented in this table). See here: http://news.bbc.co.uk/1/hi/business/1013384.stm


http://www.dti.gov.uk/energy/nuclear/technology/history.shtml

But overall this has be considered a few years ago and the conclusion was that the reactors were ageing every bit as fast as expected, extension was out of the question and their last few years of operation would require more maintenance and planned outages than previously thought. Apparently extension is not an option for the UK fleet.... can't find a link to that study though!

I have the Nuclear Decommissioning Authority report in front of me here... and they don't have a page for Dungeness B! There's a page of A and an reactor shut down date of Dec 2006.

I?m not an expert in safety of nuclear reactors but I did talk to a group who made robots for cleaning nuclear reactors and thereby extending their life. I think the general impression is that it is safe to extend the life of a nuclear reactor once it had been cleaned.

I used to work in the nuclear industry. My understanding was that the problem was not safety as such, but maintenance. You reach a point where the thing needs so many parts replacing and sevicing to keep it safe, or even just running, that you give up and shut it down. Of course, if we're running short of power, maybe they'd be prepared to do more work on reactors in return for running them for a few more years.

Sorry if I'm being a bit thick here, but what are you saying? That Dungeness B should not have had any extension? And have the decommisioning dates for all the others got an implicit (No Later!) after the dates or is this 'flexibility' something you think we may see more of?

The comment I made about was about the fleet at large rather than individual plants, I'm not surprised some can be extended, as some already have been. I don't expect to see many significant extensions like the Dungeness B though, the decommissioning schedule is already well along the planning route. There are also other problems outside the actual reactors themselves like the THOP reprocessing plant being unable to continue to handle the fuel for Magnox reactors. The more I look into it the more complicated it seems to be but the trend is for pretty much everything except Sizewell B, Torness and Heysham to be decommissioned within the next 15 years. Corresponding nicely with the almost complete depletion of North Sea gas.

Oh dear, I see old Sizewell B is one of the ones that's going to last the longest...

I remember something recently about them wanting to build Sizewell C, but I think it was put in the bin after a bit of an argument with the public.
I wouldn't be suprised if it's not the last I hear of the plan though.

Calder Hall !!! Still running!!!

Crikey... thats older than I am. I thought they closed that one years ago. Winston Churchill signed the order for that one when he was Prime Minister.

Old? Thats Jurassic Park. Must be one of the oldest functioning reactors on the planet. If not the oldest.

Nah, Calder Hall's closed.
Quote:
With the closure, in March 2003, of reactor no. 1 at the Calder Hall station, an end had come to the oldest Magnox station of the U.K. Although it was the oldest, in 2000, there was still the assumption that Calder Hall would operate until 2006 but by late 2001, all four reactors were closed when Calder Hall experienced the same graphite shrinkage and distortion problems as Chapelcross had. Reactor no. 1 was later restarted, but reactors 2 to 4 were never put back into operation because BNFL considered the costs for measures to prevent graphite shrinkage too high.
