KARA SEA RADIONUCLIDE INVENTORY FROM NAVAL REACTOR DISPOSAL

The ORIGEN2 computer code was used to estimate the guantities of radio nuclides contained in naval reactors disposed in the Kara Sea. At the time of disposal the reactors contained 17 to 66 kCi of actinides, 1.7 to 4.8 MCi of fission products, and 0.9 to 1.1 MCi of activation prod ucts in reactor components and primary system corrosion products The c urrent inventory is 5.8 to 24 kCi of actinides, 0.49 to 0.54 MCi of fi ssion products, and 120 to 130 kCi of activation products in reactor c omponents and primary system corrosion products.
