RESPONSE TO IE BULLETD180-15 Request No. 1 Within 10 days of the date of this Bulletin, verify by direct inspection, in conjunction with the ap-propriate telephone company representative, that the ENS at your facility is powered in the manner described in the two enclosures.

Answer: The NRC was notified on June 30, 1980 that our emergency noti-fication system (ENS) is not connected to a safeguards in-

-strumentation bus backed up by automatic transfer to batteries and an inverter or an equally reliable power supply.

Upon subsequent investigation it was found that the station package was located and powered at the local telephone company (HUNTEL). This is contrary to the notification previously made on June 30, 1980.

Request No. 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.

Answer: The Station package is powered at the local telephone company office. The emergency power system consists of batteries powered by redundant chargers and a standby diesel generator that starts on loss of power.

Request No. 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 f!RC 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.

Answer: The local telephone company will not conduct the required test because this would result in a total momentary loss of power to their entire system. -

Request No. 4: If it is determined that a station package requiring on-site power is not connected to a safeguards in-strumentation 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 sucn determination.

Request No. 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.

Answer: Special Order No. 30 has been issued by the Plant Manager in connection with the " Loss of Emergency Notification System" (Red Telephone).

Request No. 6: Provide a written report, within 75 days of the issuance of this Bulletin, describins .he 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.
