Enclosure Edwin I. Hatch Nuclear Plant - Unit 2 Special Report 2-94-002 Inappropriately Terminated Fire Watch Results In Special Report as Required by the Fire Hazards Analysis A. _R_tquirement For Report This report is requt . ., we riant Hatch Unit 2 Technical Specifications, Section 6.9.2, and the Plant Hatch Fire Hazards Analysis, Appendix B, Section 1.1.1.

Specifically, Technical Specifications, Section 6.9.2 states:

Special Reports for fire protection equipment operating and surveillance requirements shall be submitted, as required, by the Fire Hazards Analysis (FHA) and its Appendix B requirements.

FHA Appendix B, Section 1.1.1, states:

Fire-rated assemblies and sealing devices in fire-rated assembly penetrations separating portions of safety-related fire areas or separating redundant systems important to safe shutdown within a fire area shall be OPERABLE.

Furthermore, Action Statement (a) of Appendix B, Section 1.1.1, allows the fire rated assembly and/or sealing device to be inoperable for up to 14 days provided, within I hour, a continuous fire watch on at least one side of the affected assembly (ies) and/or sealing device (s) is established, or fire detectors are verified operable on at least one side of the inoperable barrier and an hourly fire watch patrol is established. In the event described in this report, a required hourly fire watch patrol was inappropriately tenninated.

B. Unit Status At Time Of Event On 10/7/94, at 0200 EDT, Unit I was shutdown for a refueling outage with all fuel removed from the reactor vessel. Unit 2 was in the Run mode at a power level of 2358 CMWT (96.8% rated thennal power).

• Spe'cial Report 2-94-002 C. Descrintion Of Event On 6/29/92, an hourly fire watch patrol was initiated for fire area 0040 to implement compensatory actions in response to NRC Bulletin 92-01. The hourly fire watch .

patrol for the fire area mentioned above was terminated on 10/2/94 due to removal of all fuel from the Unit I reactor vessel. The operating and surveillance requirements for fire-rated assemblies contained in the FHA are applicable when fuel is in the reactor vessel. l On 10/7/94, at 0200 EDT, a licensed shift supervisor was performing a review of FHA related Limiting Conditions for Operations (LCO) and discovered that the required hourly fire watch patrol had been inappropriately terminated for fire area 0040. The fire area is common to both units and '5e fire watch should have been maintained to satisfy the FHA requirements for Unit 2. Deficiency Card 1-94-2650 was written to document the failure to maintain the required fire watch. The hourly fire watch patrol for the affected area was re-established on 10/7/94 at 0230 EDT as required by LCO 1-92-420.

D. Cause OfThe Evgg The cause of the inappropriate termiaation of the fire watch in fire area 0040 was personnel error. Specifically, licensed personnel did not recognize that fire area 0040 is common to both units.

E. Analysis Of Event In this event, a required hourly fire watch patrol for fire area 0040 was not performed from 10/2/94 to 10/7/94. Upon discovery of the condition, an hourly fire watch patrol was re-established for the affected fire area in accordance with FHA Appendix B, Section 1.1.1.

The fire area affected by this event is equipped with a full coverage linear thermal detection system which, in the event of a fire, would provide an alarm both locally and in the Main Control Room to ensure prompt response by the plant fire brigade. The area is also protected by a wet pipe sprinkler system which would rapidly extinguish a fire. Additionally, a hose station and portable carbon dioxide fire extinguishers are ,

available in nearby fire area 0014.
