RE0 VEST FOR ADDITIONAL INFORMATION
_SECOND TEN YEAR INSERVICE INSPECTION INTERVAL COPMONWEALTH EDISON CONPANY BYRON STATION. UNITS 1 AND 2 DOCKET N05. STN 50-454 AND STN 50-455 The licensee has requested relief from the requirements of IWA-5242(a) which states that for systems borated for the purpose of controlling reactivity, insulation shall be removed from pressure retaining bolted connections for VT-2 visual examination. The licensee has an extensive program for addressing boric acid leaks once detected. However, the proposed alternative may not ensure that small leaks will be detected; thus, may not provide an acceptable level of quality and safety. Other plants are removing insulation during outages to perform direct visual examination for evidence of boric acid leakage. This alternative is also contained in Code Case N-533. Has this option been considered? Provide a discussion regarding this option or other alternatives that will ensure the detection of small leaks in borated systems.
