BWR owners and plant fabricators have been making efforts to decrease the ISI parts where UT is difficult to be conducted. For that purpose, UT verification test for both detection and sizing qualification through deposit of pipe weld joint started in 2009 and will last until 2011. In 2009, UT verification test for stainless steel pipe weld joint has been performed. Test samples are stainless steel pipes with welds and sizes are 600A.350A.150A with EDM notches and/or SCC cracks. Angle beam methods and...

In this study, a quantitative evaluation method on maintenance level which is determined by the two factors, maintenance plan and field work implementation ability by maintenance crew is discussed. And also a quantitative evaluation method on safety level for giant complex plant system is discussed. As a result of consideration, the following results were obtained. (1) It was considered that equipment condition after maintenance work was determined by the two factors, maintenance plan and field work ...

In this study, a relation among maintenance optimization, maintenance performance target and maintenance importance is discussed. And the definition of maintenance importance and its quantitative evaluation method is also discussed. As a result of consideration, the following results were obtained.. (1) Clearly different from natural or physical phenomena, it is difficult to determine a maintenance plan as a single optimum solution. An optimum maintenance plan can be obtained by setting maintenance ta...
