Numerous studies of the effects of impurities and fast neutron irradiation on fracture toughness of nuclear reactor pressure vessel materials (plates; forgings; and welds) have been reported in the literature [1-9]. Most such studies have included a minimum number of tests for each material and/or combination of irradiation parameters. Statistical analysis of neutron irradiation effects has been possible only by using a large body of data representing a variety of materials and neutron exposure conditions. However; such analytical methods do not address the question of accuracy of each datum in the large set; or the accuracy and reliability of results from a single small data set such as might be obtained in a nuclear reactor pressure vessel surveillance study. The present study addresses this question by multiple testing at two laboratories of typical nuclear pressure vessel materials (both irradiated and unirradiated) and statistical analyses of the test results. Multiple tests were * Research sponsored by the Office of Nuclear Regulatory Research; US Nuclear Regulatory Commission; under In-teragency Agreements DOE 40-551-75 and 40-552-75 with the US Department of Energy under contract DE-AC05-84OR21400 with Martin Marietta Energy Systems; Inc. ** Materials Engineering Associates; Lanham; Maryland; USA;
