History

The construction of the power station, which was undertaken by a consortium of AEI and John Thompson[1] began in 1956.[2] It had two Magnox reactors producing 276 megawatts (MW) in total – enough electricity on a typical day to serve an urban area the size of Bristol. The reactors were supplied by The Nuclear Power Group (TNPG) and the turbines by AEI.[3] Electricity generation started in 1962 and ran for 27 years to 1989.

Nuclear fuel for Berkeley power station was delivered and removed via the nearest railhead, a loading facility on the Sharpness single railway line. This included a dedicated siding and a gantry crane.[4]

Specification

Berkeley had 4 × 83 MW turbo-alternator generators, giving a gross capability of 334.4 MW and a net capability of 276 MW.[5] The steam conditions at the turbine stop valve were 20.3 / 3.9 bar and 319 / 316°C. In the year 1978/9 the station generated 1392.63 GWh, and in 1980/1 the station generated 1,003.923 GWh, The overall thermal efficiency of the station in 1981 was 21.12 per cent.[5]

Closure

Reactor 2 was shut down in October 1988, followed by Reactor 1 in March 1989. Berkeley was the first commercial Nuclear power station in the United Kingdom to be decommissioned following its closure in 1989. So far the nuclear decommissioning process has involved the removal of all fuel from the site in 1992, and the demolition of structures such as the turbine hall in 1995 and cooling ponds in 2001.[6] The next step of decommissioning will be the care and maintenance stage of the nuclear reactor structures, scheduled to commence in 2026, until radioactive decay means that they can be demolished and the site completely cleared between 2070 and 2080.[7]

The site in 2014

In March 2012 five of the 310-tonne boilers were moved from the station to Sweden for decontamination and recycling.[8][9]

In December 2013 the Nuclear Decommissioning Authority selected Berkeley as the preferred interim store for Intermediate-level waste from the decommissioned Oldbury nuclear power station.[10][11] This became operational in 2014.[12]

Berkeley is one of four nuclear power stations located close to the mouth of the River Severn and the Bristol Channel, the others being Oldbury, Hinkley Point A and Hinkley Point B.

Berkeley Nuclear Laboratories

Just south of the power station were Berkeley Nuclear Laboratories, one of the UK’s three main nuclear power industry research centres. At its peak about 750 staff worked at the labs including 200 scientists and engineers.[13]

By 2016 the site, and some surrounding land, was converted into a 50-acre technology park now called Gloucestershire Science & Technology Park, by a subsidiary of South Gloucestershire and Stroud College. At the centre of the site the former engineering rig hall, building D24, the John Huggett Engineering Hall, was converted into a college engineering campus.[14][15][13] Alongside which was built a university technical college. The site now accommodates a large number of prestige occupiers including Bloodhound LSR and Gloucestershire Police.

gollark: Well, yes, that probably doesn't help much.
gollark: In an individual interaction, vengeance is bad, because you're just harming someone even though doing it afterward won't cause them to have not done the thing for which you are taking revenge.
gollark: Which kind of works even if you haven't taken vengeance on *anyone* yet, if people *think* you are likely to.
gollark: As I said, if people know "hmm yes if I do bad things to this person they will have VENGEANCE" they are less likely to do those bad things.
