Rosenergoatom plans to launch tender at the end of April to conduct a feasibility study for preparing nine reactors for decommissioning between 2016 and 2020. A subsidiary of Rosatom, Rosenergoatom operates all of Russia's civilian nuclear power plants.
 
The aim of the study is to determine the work required in the most cost-effective manner to decommission Beloyarsk units 1 and 2, Bilibino units 1-4, Leningrad 1 and 2 and Novovoronezh unit 3. Cost calculations should include the management of used nuclear fuel, Rosenergoatom said.
 
The initial maximum contract value is RUB 7.622 billion ($132 million).
 
The tender is scheduled for 30 April and applications to take part are due by 9 April.
 
All the units are light water graphite reactors, apart from Novovoronezh 3, which is a pressurised water reactor.
 
Beloyarsk 1 is a 108 MWe reactor that was commissioned and withdrawn from service in 1964 and 1983, respectively. Unit 2 is a 160 MWe reactor that was commissioned and withdrawn from service in 1969 and 1990.
 
Bilibino 1-4 are each 11 MWe and were commissioned between 1974 and 1977 and are scheduled to be shut down between 2019 and 2021.
 
Leningrad 1 and 2 each have a net capacity of 925 MWe. They were commissioned in 1974 and 1976, respectively, and are scheduled to be shut down in 2018 and 2020.
 
Novovoronezh 3 has a net capacity of 385 MWe that started operations in 1972 and is scheduled to be shut down in 2016.
