Nuclear power in the United Kingdom became a public limited company, British Nuclear Fuels plc, wholly owned by the UK government. A Thermal Oxide Reprocessing Plant (THORP) was opened at Sellafield in 1994. Construction had begun in the 1970s and cost £2.4 billion. The Sizewell B nuclear power plant was built and commissioned between 1987 and 1995, and began producing power for the national grid in February 1995. Its construction followed a four-year, 16 million-word public inquiry. As of 2014 it is the most recent nuclear plant to be constructed in the United Kingdom.

Beloyarsk Nuclear Power Station in the region, as the radiation monitoring effort was extended in recent years. Beloyarsk Nuclear Power Station The Beloyarsk Nuclear Power Station (NPS; []) was the third of the Soviet Union's nuclear plants. It is situated by Zarechny in Sverdlovsk Oblast, Russia. Zarechny township was created to service the station, which is named after the Beloyarsky District. The closest city is Yekaterinburg. Two earlier reactors were constructed at Beloyarsk: an AMB-100 reactor (operational 1964–1983) and an AMB-200 reactor (operational 1967–1989). Both were supercritical water reactors; the first unit used 67 tons of uranium enriched to 1.8%, while the second unit
