概要
Baffle Former Bolts (BFBs) in PWR nuclear plant have the possibility to be cracked due to Irradiation Assisted Stress Corrosion Cracking (IASCC). The maintenance guideline for BFBs had been established from Thermal and Nuclear Power Engineering Society in 2000, and BFBs have been maintained in accor dance with this maintenance rules. Recently, the new edition of this guideline has been published in order to reflect latest IASCC data and more preci se stress evaluation of BFB into maintenance rules. The summary of the revised contents and these improvement activities are introduced in this paper.
