Gentlemen:

Enclosed is II Bulletin No. 80-15 which requires action by you with regard to your power reactor facility and/or fuel facility with an operating license.

In order to assist the NRC in evaluating the value/ impact of each Bulletin on licensees, it would be helpful if you would provide an estimate of the

=anpower expended in conduct of the review and preparation of the reporr(s) reqqired by the Bulletin.

Please estimate separately the manpower associated with corrective actions necessary following identification of problems through the Bulletin.

20555 IE Bulletin No. 80-15 Date: June 18, 1980 Page 1 of 2 POSSIBLE LOSS OF EMERGENCY NOTIFICATION SYSTEM (ENS) WITH LOSS OF 0FFSI7 P ATER In the past year, there have been two occurrences where a loss of off-site power has resulted in a loss of communications between a power reactor facility and the NRC Operat:ons Center via the Emergency Notification System (ENS). The most recent occarrence was at Indian Point Unit 2 on June 3, 1980.

The earlier event occurred at the Davis Besse facility on October 15, 1979 and resulted in the issuance of IE Circular 80-09.

The installation of the ENS requires a station package which operates on 110 VAC.

In some cases, the station package is located at the local telephone company which supplies the required power for normal operation and. emergency power for operation during abnormal occurrences, but in many cases, the package is located at the site and is served by on-site power.

In some c= _; where the station package is served by on-site power, the station package has not been backed up by emergency power.

NRC data indicates that the station packages for each facility are powerad in the manner described in the two enclosures.

Actions to be taken by all licensees:

1.

Within 10 days of the date of this Bulletin, verify by direct inspection, in conjunction with the appropriate telephone company representative, that the ENS at your facility is powered in the manner described in the two enclosures.

2.

Those facilities which have station packages requiring on-site power, but which are not connected to a safeguards instrumentation bus which i, backed up by batteries and an inverter or equally reliable power supply, shall make necessary modifications and provide such a connection.

3.

All facilities are to develop and conduct a test, within 60 days of the issuance of this Bulletin, to verify that all extensions of the ENS located at your facility (ies) would remain fully operable from the facility (ies) to the NRC Operations Center in the event of a loss of offsite power to your facility (ies).

This is not intended to mean that an actual loss of offsite power be executed.

IE Bulletin No. 80-15 Date:

June 18, 1980 Page 2 of 2 4.

If it is determined that a station package requiring on-site power is not connected to a safeguards instrumentation bus backed up by automatic transfer to batteries and an inverter or an equally reliable power supply, notify the NRC Operations Center via the ENS within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after such determination.

5.

Prepare and issue an administrative procedure or directive which requires notification to the NRC Operations Center by commercial telephone or relayed message within one hour of the time that one or more extensions of the ENS located at your facility (ies) is subsequently found to be inoperable for any reason.

6.

Provide a written report, within 75 days of the issuance of this Bulletin, describing the result of the reviews required by items 1 and 2 above, the results of the testing required by item 3 and the procedures required by item 5.

This information is requested under the provisions of 10 CFR 50.54(f).

Accordingly, you are requested to orovide within the time periods specified in item 6 above, written statemen.s of the above information, signed under oath or affirmation.

Reports shall be submitted to the Director of the appropriate NRC Regional Office and a copy forwarded to the Director, NRC Office of Inspection and Enforcement, Washington, D.C.
