Subject:

Canister Contents Weight for MAG-TSC-418-099 This memo is to document generation, review, and approval of canister contents weight for MAG-TSC-418-099. This is to support NAC analysis in resolution of helium backfill issues documented in Duke NCR 02211048.

The canister contents weight is conservatively calculated as 55,906 lbs (53,807 lbs for fuel assemblies and 2,098.4 lbs for nonfuel hardware). This is based on fuel assembly and component types identified in Reference 1 and maximum weights documented in Reference 2.
