OSTI ID:6561527
This study provides an analysis of alternatives for conducting independent verification testing of environmentally qualified safety-related equipment which is required to operate in nuclear plant safety systems. Three major alternatives were costed and compared: (1) NRC dedicated test facility; (2) NRC contracts for testing to existing test laboratories; (3) NRC review and witnessing of vendor tests. To formalize the evaluation, eleven specific criteria were identified against which the alternatives were compared. None of the alternatives singly show clear advantage; but in the dual combinations, an 'optimal' alternative emerges when alternatives 1 and 3 are considered in union. This study also illustrates the magnitude and immediacy of the equipment environmental qualification issue. It recommends that dedicated NRC staff be assigned to qualification programs review and that other NRC staff continue this study to define, coordinate, and implement an optimal alternative.
