ATTACHMENT SAFETY EVALUATION Introduction During defueling the licensee intends to place end fittings in shielded 55 gallon drums which will be inside an overpack container. The. drums will be transferred to and placed in a storage area adjacent to the west "D" ring on the 347 ft. elevation of the reactor building. As tooling and methodologies are developed the end fittings will be sized to fit through the openings in defueling canisters and ultimately transferred offsite. There may be some fuel attached to or packed in flow spaces in the end fittings. Since the

-accumulated fuel contained in a drum or several drums could exceed 450 grams of combined uranium-235, uranium-233 and plutonium criticality monitoring is required per 10 CFR 70.24.

Evaluation The licensee proposed to add two criticality monitors to cover the end fitting storage area. The monitors meet the requirements of 10 CFR 70.24. The attached surveillance requirements for these detectors are the same as the arveillance requirements for the existing criticality monitors in the reactor and fuel handling building and are the same as the surveillance requirements in the standard B&W Technical Specifications (NUREG 0103).

Conclusion The proposed monitoring system meets the requirements of 10 CFR 70.24. The monitoring system will enhance safety by alerting personnel if a criticality event were to occur. .The change will not result in any environmental effects and falls within the scope of activities previously considered in the Programmatic Environmental Impact Statement.
