Research Laboratory in Demokritus Laboratories for research purposes. Serbia currently operates a single nuclear research reactor in the Vinča Institute. Previously, Vinča Institute had two active reactors: RA and RB. In the 1958, nuclear incident happened. Six workers received critical amount of radiation and one of them died. These workers received first bone marrow transplant in Europe. After, Chernobyl disaster, in 1989, moratorium on use of nuclear energy was in power. Later, the law officially prohibited use of nuclear energy. To this day, Directorate for Nuclear and Radiation Safety (Srbatom) is strongly opposed to any kind of nuclear energy use in Serbia or neighbouring countries. The future expansion of nuclear power in the United Kingdom to make up 25% of electrical production was announced in March 2022. The country has a number of reactors which are currently reaching the end of their working life, and the future of nuclear in the UK was uncertain. The government has now said it could approve up to eight new reactors to help reach a target of generating 24GW of the total from nuclear power plants. The UK has succeeded in reaching its targets for reduction on CO2 emissions in 2020 in part thanks to nuclear power, its situation may be made worse if new nuclear power stations are not built. The UK also uses a large proportion of gas-fired power stations, which produce half the CO2 emissions as coal, but there have been recent difficulties in obtaining adequate gas supplies. In 2016 the UK government committed to support the new Hinkley Point C nuclear power station. As of 2021, the Hinkley Point C is under construction and 3% over budget largely due to the COVID-19 pandemic. The UK Government is also under talks with EDF Energy for a new nuclear power station at Sizewell C nuclear power station, it is also considering aid in a variety of options at Wylfa nuclear power station, Moorside nuclear power station and Bradwell B nuclear power station signifying a strong will to preserve a large portion of nuclear energy in its energy mix as an effort for further decarbonisation. Sweden A year after the Three Mile Island accident in 1979 the 1980 Swedish nuclear power referendum was held. It led to the Swedish parliament deciding that no further nuclear power plants should be built, and that a nuclear power phase-out should be completed by 2010. On 5
