【 摘 要 】

This calculation demonstrates that the MCNP code is a viable tool for determination of the direct and skyshine radiation dose contributions from the proposed repository aging areas. The code provides statistically satisfactory results, which compare favorably to those for similar existing NRC-certified storage casks. The design parameters selected for the aging system produce some measurable effects on the dose rates both inside and outside the aging pads. In particular, the cask array pitch affects the worker dose calculated inside the pad, and the skyshine dose beyond the protective area fences. The effect of the pad spacing is relatively minor.
