Characteristics of the IAEA Correlation Monitor Material for Surveillance Programs

Source

Within the International Atomic Energy Commission (IAEA) coordinated program on the optimizing of reactor pressure vessel surveillance programs and their analysis, Phase 3, a specially tailored "radiation sensitive" correlation monitor material has been fabricated. This material will serve as a reference to the IAEA program for future vessel surveillance programs throughout the world.

An extensive evaluation of the correlation monitor material in the as-received condition has been carried out in Finland and the results are presented here. The mechanical properties measured at different temperatures include Charpy V-notch and instrumented precracked Charpy data, and elastic-plastic fracture toughness (J and T). The specimen size and geometry have been varied in the tests. Correlation between different fracture properties are evaluated and discussed.
