Title:
加速試験方法
Document Type and Number:
Japanese Patent JP6911510
Kind Code:
B2
Abstract:
To provide a method for generating a stress corrosion crack (SCC) in a shorter time than an actual time and correctly evaluating the life of SCC generation without changing the mechanism and stochastic characteristics of the SCC generated in an actual atomic reactor.SOLUTION: An acceleration testing method includes a step A of whether space distribution of the number of SCC generation follows Poisson distribution in an SCC generation acceleration test.SELECTED DRAWING: Figure 2
