8005050072 IE Bulletin No. 80-15 POSSIBLE LOSS OF EMERGENCY NOTIFICATION SYSTEM (ENS) WITH LOSS OF OFFSITE POWER 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 Operations Center via the Emergency Notification System (ENS).
The most recent occurrence was at Indian P.oint Unit 2 on June 3, 1980.
The earlier event occurred a:t 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 teJephone 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 cases where the station package is served by on-site power, the station package*has not been backed up by emergency power.
NRC data indicate that the station packages are powered in the manner described in the enclosures.
Actions to be taken by all licensees:
- 1.
Within 10 days of the date of this Bulletin, determine by direct inspection, in conjunction with the appropriate telephone company representative, the manner in which the ENS at your facility is powered.
- 2.
Those facilities which have station packages requiring on-site power, but which are not connected to a safeguards instrumentation bus which is 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 June 18, 1980 Page 2 of.2
- 4.
If it is determ1ned 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 whjch 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).
