【 摘 要 】

This citation note documents both the refined methodology (technical approach and supporting basis) and the results for adjusting the currently available average exposure and consequential radioisotopic source term for K-East and K-West Basin uranium-bearing sludge. This refinement more accurately accounts for local peaking factors known to occur in the fuel elements during irradiation in N Reactor, at the locations that have subsequently been observed to be the primary sources of fuel related sludge in the K Basins. The heavy metal and fission product material originated almost entirely from spent nuclear fuel from the Hanford N Reactor. This calculation note documents the methods used to characterize radionuclides in KE and KW Basins.
