NF Decomm: Minatom’s engagement

The tempo of defuelling activities kept pace with the budget increase. In 1998, four nuclear submarines were defuelled in the Northern Fleet, while in 1999, the number increased to six. I n 2000, according to official returns, 14 submarines were defuelled. In 2001, 16 submarines have been earmarked for defuelling, assuming the availability of funding.

Funding, $m 1998 1999 2000 2001 (planned)
Federal budget 4.1 6.4 5.1
HEU sales 13.8 28.2
Minatom’s budget 3.6 6.9
Total 4.1 23.8 40.2 90.7

Minatom also has the responsibility to ensure that no superfluous infrastructure is built. According to Minatom, the number of submarines defuelled per year can easily be increased to 30, but this will require an expansion of a type of infrastructure which will become useless once the spent nuclear fuel is unloaded from all retired submarines. Minatom considers that the optimal solution would be to dismantle 20 to 25 submarines per year. At this rate, the problems revolving around decommissioning would be resolved within six to seven years. The cost would be around $71.4 million per year.
