Criticality safety studies of Building 3019 Cell 4 and in-line storage wells

摘要

New fissile material load limits for storage facilities located in Building 3019 are derived in a manner consistent with currently applicable Martin Marietta Energy Systems requirements. The limits for (sup 233)U loading are 2.00, 1.80, 1.45, and 0.19 kg/ft for hydrogen-to-(sup 233)U atoms ratios of 3, 5, 10, and unrestricted, respectively. Limits were also found for (sup 235)U and (sup 239)Pu systems. The KENO-Va Monte Carlo Program and Hansen-Roach cross sections were used to derive these limits.
