How many nuclear power plants are there in Britain?

Answer 1

In the UK a total of 19 nuclear plants were built, of which 11 were magnox, 7 AGR, and one PWR.

The Magnox ones were: Calder Hall, Chapelcross, Berkeley, Bradwell, Dungeness A, Hinkley point A, Sizewell A, Hunterston A, Trawsfynedd, Oldbury, Wylfa.

Calder and Chapelcross had 4 reactors each. These were the prototypes and were initially built mainly to produce Plutonium though each reactor generated about 50 MWe.

The subsequent ones were commercial and owned and operated by the CEGB, and had 2 reactors at each site. Up to Oldbury they all had steel vessels, Oldbury and Wylfa had reinforced concrete vessels with much greater integrity, which led onto the AGR design of vessel. All magnox are now shutdown except Oldbury and Wylfa, which soon will also be shutdown.

The AGR stations were Dungeness B, Hinkley Point B, Hunterston B, Hartlepool, Heysham 1, Heysham 2, Torness. These all had 2 reactors and concrete vessels. The output of Heysham 2 and Torness, which were identical designs, was 660 MWe per reactor. All these units are operating, the scheduled shutdown for the last two is 2023.

One PWR was built at Sizewell B and is in operation. This was the swansong for the CEGB which was broken up and privatised by the Thatcher Government, and no body that followed had the commercial strength or desire to build nuclear.

If new build goes ahead, it will probably be under French direction and ownership.

Answer 2

The link below gives all electricity producing plants in the UK. Many are very small wind or hydro plants, but you can extract the identities of larger plants if that is what you are after. See Table DUKES 5.11 from the list of tables.

Answer 3

AGR plants at Dungeness B, Hinkley Point B, Hunterston B, Heysham 1 and 2, Hartlepool, Torness. Magnox plants mostly shutdown, the last two in operation were Oldbury and Wylfa. Spent fuel processing at Sellafield.

Answer 4

119 power stations of more than 1 MW and 4440 smaller stations (mostly self generators)

See the links below

Answer 5

There are seven AGR stations each with two units, one PWR, and I think two magnox units still operating

Answer 6

There are 14 AGR reactors, 1 PWR, and 2 magnox reactors operating
