... Abstract Lead-based reactors mostly adopt integrated pool structures to simplify the design of reactor and have high inherent safety. As an important safety facility in the primary circuit, the reliability of the reactor vessel is critical for the safe operation of the whole reactor...

..., the development of the robotics in the last 30 years has made this evolution possible, contributing to optimize the critical component inspection time in terms of quality and productivity. The safety operation and significance of reactor vessel is obvious to the nuclear power station. The application of NDT...

... temperature up to 240 degree C. The characteristics and durability at elevated temperature for Halbach type EMAT in 200 hours under the 200 degree C are reported. Twenty to thirty percents of sensitivity reduction can be observed but this is enough for MONJU ISI. MONJU Reactor Vessel In-service...

.... The current requirements for inspection of reactor vessel pressure-containing welds have been in effect since the 1989 Edition of American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section XI, supplemented by U.S. Nuclear Regulatory Commission (NRC) Regulatory Guide 1.150, June 1981...

... 25 11 2008 A cost-benefit-risk study of the best (in terms of plant valuation) long-term strategy for canopy seal weld leakage control and prevention including a span of options for reactor vessel head J-Groove weld failures is performed. The range of options goes from the “do nothing...

... for the industry. The updates to the methodology and input, pilot plant evaluations, results, process for demonstrating applicability of the pilot plant analysis to non-pilot lead plants and lessons learned from the evaluations performed are summarized in this paper. Reactor Vessel PTS Risk-Informed...
