Acquisition, compilation and critical analysis of technical specifications and qualification procedures for new-qualification and in-service inspection of safety-related electrical equipment in nuclear power plants

The result of the critical analysis of the qualification specifications and qualification procedures can be summarized as follows: 1.) The qualification of safety-related electrical equipment is done in several complementary and overlapping stages: proof of success in operation; type test; suitability test; works tests; setting to work tests; in-service inspection. 2.) All the proofs and tests mentioned have now been laid down in KTA Regulations or draft KTA Regulations or have been agreed between the institutions concerned, as no regional differences or differences specific to certain plants can be found in qualification specifications and methods. 3.) Due to the great participation or responsibility of experts according to paragraph 20 of the Atomic Energy Law, in the context of the qualification tests there are no differences between the nuclear technology regulations and the technical specifications used in practice. 4.) The technical specifications and processes used in qualification are suitable and sufficient to prove the required quality. Improvements are necessary at several points. (orig./HP)
