The International Atomic Energy Agency (IAEA) organized an international Coordinated Research Project (CRP) on qualification, condition monitoring, and management of low voltage cables for life management in nuclear power plant. A total of 16 organizations from Technical Service Organizations (TSOs), and Research & Development Organization participated in the CRP and tested and presented their experimental results. The CRP members are actively engaged in providing cable samples, thermal and radiation ageing of cables, and electrical, mechanical, and chemical testing of cables samples.
Preliminary analysis of the test data received show that, for some of the Condition Monitoring (CM) methods, good correlation is observed with ageing time and there is consistency in measurements between the different test labs carrying out the tests. The level of correlation with ageing time and the degree of variability between labs is dependent on the material being tested and the CM method being used.
