Different British nuclear reactors?

They're British.

They're already so pale they glow in the dark. (Says the redhead)

In fact, there were a couple of generations of it. A standard 500 MWe turbine-generator set went into 10 coal and 4 oil fired plants ordered from 1961 onwards. From 1967, an enlarged 660 MWe set went into one coal, two oil, and the AGR plants. There seems to have been some talk of a 900 MWe supercritical unit in the 1980s, but that never came to fruition.

A little more information from Earth Science Conservation No.25 in 1988 on the 900 MWe plant. In 1986, eight were projected to be built:

• Fawley B
• West Burton B
• Kingsnorth [presumably B]
• Inswork Point
• Marchwood
• Barking
• Hams Hall
• Killingholme

Applications were made for Fawley B and West Burton B, and Kingsnorth was expected to be requested in autumn 1988. They would be coal fired plants built with flue gas desulfurisation and low NOx burners. A model of the proposed Fawley B plant is shown on the 28 Days Later forum here. Presumably the others would have been similar.

There was also a map in New Scientist at some point in the 1970s or early 1980s showing sites identified for potential future reactors. There were... a lot.

Found the map - it's not from New Scientist at all, but from the 1985 book Geographical Dimensions of Energy:



In the course of looking for this, I did find a Nature article from 1971 indicating plans for:

• A 2,500 MW (presumably four unit) AGR plant at Connah's Quay
• A 1,300 MW (presumably two unit) AGR plant at Portskewett
• Oldbury B, a prototype HTR plant of 650 MW, building on experience with the Dragon reactor.

The planned full-scale HTR was abandoned as it was competing with the SGHWR for funding. Some sources suggest that it may have been a 1,320 MW plant - presumably twin reactor, as there were competing TNPG and BNDC designs for the plant of 650 MWe and 750 MWe respectively.

A number of oil-fired plants were also planned at this time which didn't come to pass:

• A 4,000 MW plant (presumably 6 x 660 MWe, similar to Drax) at Killingholme
• A plant at Inswork Point in Devon - this was to be 2 x 660 MWe
• Redevelopment of Brunswick Wharf in London - based on the total of 7,200 MWe, this would logically be 3 x 660 MWe similar to Littlebrook.

There's also reference in an IAEA conference paper from 1970 to the above AGR and HTR plants, plus an AGR at Stourport. This latter plant seems to have been defeated by local opposition. The Portskewett plant actually progressed to a planning application, which ran out of time and the plant was abandoned in 1979.

It should be seen that the CEGB's projected construction of new plant through the 1970s and 1980s anticipated a growth in demand that wasn't particularly realistic!
