SUBJECT:

CASE STUDY REPORT - OPERATING EXPERIENCE RELATED TO 1101STURE INTRUSION IN ELECTRICAL EQUIP!iDIT AT C0ittiERCIAL POWER REACTORS Following resolution of peer review comments, we have completed the enclosed study of moisture intrusion in electrical equipaent at commerical power reactors. The report is being forwarded for your information and use as you deem appropriate.

i The report provides: (1) a review of the operating events related to moisture intrusion in electrical equipment at commercial power reactors; (2) an analysis and evaluation of these operating events; and (3) recommenda--

tions that, if implemented, could reduce or prevent most of the failures reported.

If you have any questions regarding this report, please contact Medhat El-Zeftawy of my staff. Mr. El-Zeftawy can _be reached at (301) 492-4434.
