More nuclear drivel. They all start off saying that. The problems only become apparent when they (try to) get a commercial one up and working. A nuclear Lala Land always just over the horizon. Drivel on the internet. The internet is not an encyclopedia.
Yes, and was what led to the stuff we have to clean up today. That this was the case, and has nothing to do with reactors built today or planned is too hard a concept for the likes of harry to grasp.
Not true, by the 1970's plutonium production technology was well sorted, none of the existing weapons powers were bothering to try to piggy-back on civil nuclear. There was a certain amount of debate in the UK about whether or not some weapons grade plutonium "escaped" from the civil programme. When Magnox plant are started up, they started to refuel relatively soon so as to settle into an equilibrium fuelling regime. The early discharge fuel is potentially "weapons grade", but after a year or two of operation it is not.
Chapelcross & Calder Hall were owned by AEA then BNFL and built primarily for plutonium production. The rest of the UK Magnox stations were owned by GEGB & SSEB. The plutonium production reactors initially got through a complete change of fuel every 6 months, the electricity generators about 18 months. The AEA owned reactors swapped between making weapons grade fuel and being optimised for electricity until at least the late 1980s. The number of spent fuel flasks leaving Chapelcross could be used to estimate how it was operating.
Several of the Magnox power reactors had the fueling capacity to operate for weapons grade plutonium production but were operated under IAEA safeguards for civil reactors so it's unlikely that diversion of plutonium took place.
The AGR reactors were designed to achieve a higher burn up of fuel and have longer beween refueling so they would have been less suitable for making plutonium. Plutonium has a very long shelf life and is recyclable (unless you blow it up). It does not appear to have been a factor in UK reactor design 45 years ago.
That's as maybe, but the MSRE from planning to being turned off happened entirely within the 60's and was something of a continuation of earlier projects from just after WW2.
The earlier reactors are apparently sitting out in the car park and open to visitors, which says something of the shorter cooling off periods and relative ease of decommissioning compared to other reactor designs.
