Abstract

As part of a cooperative study between the United States and Japan, the U.S. Nuclear Regulatory Commission (USNRC) and the Ministry of International Trade and Industry (MITI) of Japan agreed to perform a test program that would subject a large scale piping model to significant plastic strains under excitation conditions greater than the design condition for nuclear power plants. The objective was to compare the results of the tests with state-of-the-art analyses. Comparisons were done at different excitation levels from elastic to elastic-plastic to levels where cracking was induced in the test model. The vibration tests and post-test examination were carried out in Japan by the Nuclear Power Engineering Test Center (NUPEC). Input motion development and pre- and post-test analysis were carried out in the United States at the Brookhaven National Laboratory (BNL) and the Electric Power Research Institute (EPRI).

This report describes the results of the cooperative studies performed both in Japan and the United States.
