ABB March 28, 1997 Document Control Desk U.S. Nuclear Regulatory Commission Washington, DC 20555 Subject: Report of Potential Deviation per 10CFR Part 21 ZPA Ratings for Class 1E Relays Notification by: ABB Power T&D Company Inc. Power Automation and Protection Division 4300 Coral Ridge Drive Coral Springs, FL 33065 This letter is to correct the information provided in the September 17, 1996, Report of Potential Deviation related to ZPA Ratings for Class 1E Relays. The above mentioned letter was issued as a result of the Surveillance audit 96-066 and a follow-up visit performed by Yankee Atomic Electric Company at ABB Power T&D Company Inc. (PAPD) in Coral Springs, Fl. After further analysis and evaluation of the available qualification documents, ABB concluded that the only Class 1E Relays whose original ZPA should have been revised were the CRN-1, CVE, CVE-1, CVQ, KD-10 and KF. As stated in the previous report, the design and functional performance of these relays were not affected and did not change. Attached is a revised list of relays with correct ZPA ratings. Please disregard previous published ZPA ratings list, dated September 17, 1996.
