I note UK fleet is now generating less than 4GW.

Yep, me too. AIUI there are 4 of the old reactors (out of 14/16) which may never generate again, due to severe cracking of the graphite. Thats basically 2GW gone.

Inevitable really, given they are 50 years old now.

Except that EDF (french, so not so important to them?) want to move the safety goalposts so they can restart at least two of them?  Nearby residents (around Glasgow, for one) might not feel too good about that?  We might just be starting to find out who is going to pay for the decommissioning of these old ‘bomb grade’ producers, in the near future.  I expect EDF will want to walk away.

oliver90owner. The comment about bomb grade producers? How do you work that one out?

The AGR fuel cycle uses enriched uranium for a longer burnup in the reactor. The resultant plutonium isotope mix is not that suitable for weapons proliferaton purposes. A much shorter dwell in the reactor is required for that. The limitations of fuel processing and the fuel route handling rate make that very difficult. Since Thorp at Sellafield is now officially closed, now practically impossible.
