Abstract: This paper discusses a development of the quantitative method to evaluate the reliability for the maintenance plan with respect to the risk impact both for Core Damage Frequency and Plant Trip Frequency. The quantitative approach includes the considerations for the effect of the Condition Based Maintenance (CBM) changing in addition to the Time Based Maintenance (TBM), and the reliability for the maintenance plan is evaluated using the actual plant-specific maintenance information collected ...

In this study, an automatic registration system was developed that can measure 3 dimensional position and orientation of multi-range fiducials automatically using a camera, laser range finder and motion bases connected to a computer. Result of the experimental evaluation shows that the measurement takes about 50 seconds per marker and RMSE (Root Mean Square Error) of the position and orientation measurement are 3.5 mm and 1.2 degrees respectively....

We aimed to demonstrate the applicability of X-ray computer tomography (CT) with refractive contrast to the 3-dimensional (3D) imaging of minute cracks produced in weld metals of Ni-base alloy and austenitic stainless steel (SUS316L) caused by Stress Corrosion Cracking (SCC). The CT imaging experiments were performed at beam BL19B2 of SPring-8. The X-ray energy was adjusted to 37KeV using a Si double ? crystal monochromator. In summary, clear images of fine cracks in austenitic stainless steel due to ...
