An International Atomic Energy Agency (IAEA) crew of specialists accomplished a assessment of long run operational security on the Kozloduy Nuclear Power Plant (NPP) in Bulgaria. The SALTO (Safety Aspects of Long Term Operation) assessment mission was requested by the Bulgarian Nuclear Regulatory Authority (BNRA).
Kozloduy NPP, Bulgaria’s solely nuclear energy plant, has two pressurized-water reactor models in operation with an put in energy of roughly 1000 MWe every. Unit 5 went into business operation in 1987 and Unit 6 in 1991. The 9-member SALTO crew centered on facets important to secure Long Term Operation (LTO). The operation licenses of the 2 models have been prolonged till 2027 and 2029, respectively. Units 1 to four have been shut down and are being decommissioned.
During the 6-15 July mission, the SALTO crew reviewed preparedness, group and programmes associated to LTO primarily based on the related IAEA security requirements.
The assessment crew discovered plant employees to be skilled, open and receptive to options for enchancment.
The plant administration expressed a willpower to handle the areas recognized for enchancment and introduced that it will proceed cooperation with the IAEA in implementing secure LTO and ask the Government of Bulgaria to request a SALTO follow-up mission in 2023.
The crew supplied a draft report back to the plant administration and to the Bulgarian Nuclear Regulatory Authority (BNRA) on the finish of the mission. The plant administration and BNRA can have a possibility to make factual feedback on the draft. The IAEA will submit a closing report back to the plant administration, BNRA and the Bulgarian Government inside three months.
The Kozloduy Nuclear Power Plant is a nuclear energy plant in Bulgaria located 180 kilometres north of Sofia and 5 kilometres east of Kozloduy, a city on the Danube river, close to the border with Romania. It is the nation’s solely nuclear energy plant and the most important within the area. The building of the primary reactor started on 6 April 1970.[2]
Kozloduy NPP at the moment manages two pressurized water reactors with a complete gross output of 2000 MWe and 1966 MW internet. Units 5 and 6, constructed in 1987 and 1991 respectively, are VVER-1000 reactors. By 2017 Unit 5 was to be upgraded to achieve a capability of 1,100 MWe, as a part of a programme to increase the lifetime of the unit by 30 years. The older and smaller Units 1 to four had been all shut down by 2007.
