This paper discusses the possibility of in-situ quantitative evaluation of crack propagation using Eddy Current Monitoring (ECM) system in a Boiling Water Reactor (BWR) environment. For the purpose, ECM experiment was conducted at a System Safety Benchmark Facility (SSBF). The target for the monitoring was a large-scale pipe specimen made of austenitic stainless steels 304L, 316L, and carbon steel STS410, connected by weld joints of nickel based alloy 182 within the SSBF. Slits were prepared at the H...

The Fukushima Daiichi nuclear power plant's units 1/2/3 which were under operation when the Tohoku - Pacific Ocean Earthquake occurred at 14:46 March 11, 2011, were analyzed by time series evaluation from the earthquake occurrence to the tsunami invasion as to whether safety functions were effective. The shutdown function and containment function were analyzed in this paper, and it showed both the safety functions were kept effective during the earthquake occurrence to the tsunami invasion....
