Systematic safety evaluation and life extension program in NPPs

The Systematic Evaluation Programs (SEP) carried out in 80's on first-generation nuclear power plants in Spain consist in analyzing the compliance of the older plants with the safety requirements for the new ones. The most affected areas were: environmental qualification of electrical and I and C equipment; ECCS improvements; auxiliary system improvements; electrical systems; reactor protection systems; fire protection. The SEPs were followed by complementary programs on Management of Remaining Plant Life, aiming at making the facilities and SEP investments profitable. The experience gained in the SEP is important for collecting additional information for the Remaining Life Management and should be integrated with the Plant Life Extension Program (PLEX)
