Second U.S. Nuclear Regulatory Commission International Steam Generator Tube Integrity Research Program. Final Project Summary Report

摘要

This report summarizes work performed under the USNRC Steam Generator Integrity Program at Argonne National Laboratory. The areas addressed by the program include assessment of procedures and equipment used for in-service (ISI) inspection of steam generator (SG) tubes: recommendations for criteria and requirements to improve the reliability and accuracy of ISI: validation and improvement of correlations and models that are used to evaluate integrity and leakage of degraded SG tubes; and validation and improvement of correlations and models that predict the generation and progression of degradation in SG tubes as a function of aging.
