Dear Mr. Engelken:
Re f: Your letter of June 18, 1980 on IE Bulletin 80-15 (Possible Loss of Emergency Notification System (ENS) With Loss of Off-site Power)
Exxon Nuclear Company has taken the following actions as required by IE Bulletin 80-15:
'1.
Requirement - Within 10 days of the date of this Bulletin, verify by direct inspection, in conjunction with the appropriate telephone company repre-sentative, that the ENS at your facility is powered in the manner described in the two enclosures.
Action - Enclosure 1 states that the ENS at Exxon Nuclear is powered by the local telephone company. On June'24, 1981, RH Purcell, Manager, Auxiliary Operations physically inspected the ENS e'uipment located at the General Telephone Company North Richland Central Oftice.
The ENS equipment is located in the main equipment racks of the Central Office and is_ powered by the 48 volt DC batteries of the Central Of fice.
There-is not a separate 110 volt AC powered station package as implied by the Bulletin. Normal power is feed through an inverter to recharge the batteries.
An emergency diesel generator is located at the Central Office and will automatically start upon_the loss of normal power.
Routine test data for this emergency generator were reviewed.
The telephone cables from the Central Of fice go directly to the non-dial ENS telephones at Exxon Nuclear Facilities with all power being provided from the Central Office.
