Subject:
IE Bulletin No. 80-15, "Possible Loss of Emergency Notification System (ENS) With Loss. of Off-site Power" R. E. Ginna Nuclear Power Plant, Unit ~~1 Docket No.
-244
Dear Mr. Grier:
In response to Inspection and Enforcement Bulletin 80-15 dated June 18, 1980,. concerning the Emergency Notification System, the following information is provided.
New York Telephone was contacted on June 25, 1980 and confirmed that the ENS Communication is powered through their equipment.
The system is powered by 48VDC in their Central Office in Ontario.
Loss of off-site power would not affect most of the phones in this network.
Because of the NRC special instructions for the phone requirements for the resident inspector, his extension of the ENS would be inoperable during loss of off-site power.
Since the system operates continuously on DC power, no test was conducted to verify all extensions would operate with loss of off-site power.
A change to procedure Administrative Order A-.56 Communications Systems at Ginna Station has been initiated which willrequire one hour notification to the USNRC of system inoperability.
ROCHESTER GAS AHD ELECT ORP.
DATE August 29, 1980 Mr. Boyce H. Grier, Director SHEET HO.
2 To assist in evaluating the value/impact of each Bulletin on licensees, manpower expended in conduct of the review and preparation of this report is approximately one manhour.
No corrective actions were necessary.
Very truly yours, L. D. White, Jr.
Subscribed and sworn to me on this gf day of August 1980.
