NMSR PRIMARY COOLANT ACTIVITY

Finalization of the NMSR shield design in accord with the final core design required a recalculation of the activity levels in the primary coolant. This source is, in general, the dominant factor in sizing the containment gamma shield and effects the neutron shield in limited areas. The specific volumetric gamma source strengths previously reported are significantly revised downward as justified in this report. The activity source reactions and the general formula for calculating the source strengths are reviewed. Subsequent sections deal with the key parameters, fast neutron fluxes and activation cross sections, and report the results. Comparison of the revised methods of calculation with the old is incorporated as required.
