Peer review work in a Spanish PRA

According to a regulatory requirement from the Spanish Authority, the utility NUCLENOR, S.A., undertook a PRA level 1 study for the plant S.M. de Garona, a boiling water reactor, supplied by G.E., Mark I Containment type, in commercial operation since May 1971. The program plan for the study was established by NUCLENOR in June 1984; and two months later an Independent Evaluation Group (I.E.G.) was formed, integrated by (three) experienced people in the field of nuclear technology, with the mission of verifying that objectives, methodology and results of the PRA were in accordance with the document ''Interim Reliability Evaluation Program Procedures Guide, NUREG/CR-2728''. Two thirds of the peer review work have been completed; final conclusions will be reached during the next month, October (third and last meeting of the I.E.G. will be held very soon). The paper will describe my work in the I.E.G. and will show my independent conclusions, with technical reasons on their support
