Dear Sirs:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. DPR-73 Docket No. 50-320 Criticality Safety Evaluation for Increasing the TMI-2 Safe Fuel Mass Limit Attached for NRC review is the Criticality Safety Evaluation for Increasing the TMI-2 Fuel Mass Limit. This analysis demonstrates that the critical mass for TMI-2 fuel can be increased from the current administrative limit of 70 kg to 140 Kg.
The attached evaluation will be used as a baseline document in support of evaluations of future defueling activities and the Defueling Completion Report.
It will be used to demonstrate subcriticality in the various areas of TMI-2 and that transition from Facility Mode 1 to Facility Mode 2, as defined by the TMI-2 Technical Specifications, can take place.
Sincerely, o-w M. B. Roc Director, TMI-2 RDW/ emf Attachment cc:
