HATCH NUCLEAR PLANT UNITS 1 AND 2 FIRE HAZARDS ANALYSIS AND FIRE PROTECTION PROGRAM (FHA), APPENDIX B Gentlemen:

On October 24, 1986, a conference call was held between members of our respective staffs to discuss the acceptability of replacing the existing Plant Hatch Fire Protection Technical Specifications with Appendix B of the FHA. At that time, Georgia Power Company agreed to make the following mcdifications to Appendix B of the Plant Hatch FHA:

1. Paragraph 1.5.1 will be revised to include the operability of the Computer Room CO2 system.

2. Paragraph 2.2.2 will be revised to require surveillances every 62 days versus every 6 months.

As agreed, these changes will be reflected in the next revision of the Plant Hatch FHA. The two affected pages are enclosed for your information.

If you have questions or concerns regarding this matter, please contact this office at any time.

FIRE DETECTION INSTRlNENTATION OPERATING REQUIREMENTS 1.2.1 As a minimum, the fire detection f nstrunentation for each fire detection zone shown in Tables 1.2-1 (Unit 1 and Conmon) and 1.2-2 (Unit 2) shall be OPERABLE.

APPLICABILITY: Whenever equipment in that area is required to be OPERABLE.

ACTION:

With the number of OPERABLE fire detection instrunents less than required by Tables 1.2-1 and 1.2-2:

a. Within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, establish a fire watch patrol to inspect the zone with the inoperable ;instrunent(s) at least once per hour, and '

b. Restore the inoperable instrunent(s) to OPERABLE status within 14 days or prepare and submit a special report to the Commission within the next 30 days per Technical Specification 6.9.2.

SlRVEILLANCE REQUIREMENTS 2.2.1 Esch of the above required fire detection instrunents which are accessible during plant operation shall be demonstrated OPERABLE at least once f per 6 months by performance of a CHAtNEL FLNCTIONAL TEST. Fire detectors which are not accessible during plant operation shall be demonstrated OPERABLE by the performance of a WANNEL FLNCTIONAL TEST during each COLD SHUTDOWN exceeding 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> unless performed in the previous 6 months.

2.2.2 The tFPA Standard 72D supervised circuits supervision associated with '

the detector alarms of each of the above required fire detection instrunents shall be demonstrated OPERABLE at least once per 62 days. l 2.2.3 If a fire detection instrunent is determined inoperable during a surveillance or if the required surveillance frequency is exceeded, declare j the instrunent inoperable and restore the instrunent to OPERABLE' status within 14 days or prepare and submit a special report to the Commission within the next 30 days per Technical Specification 6.9.2.

LOW PRESSW E C07 SYSTEMS OPERATING REQUIREMENTS 1.5.1 The following low pressure CO2 systems shall be OPERABLE with a minimum level of 60% and a minimum pressure of 275 psig in the associated storage tank.

a. Diesel Generator Building CO2 Systems

b. Computer Room 002 System l

APPLICABILITY: At all times when the equipment in the CO2 protected area is required to be OPERABLE.

ACTION:

a. With a CO2 system inoperable, establish a conti.nuous fire . watch with backup fire suppression equipment for the unprotected area within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

b. Restore the system to OPERABLE status within 14 days or prepare and submit a Special Report to the Commission within the next 30 days per Technical Specification 6.9.2.

SURVEILLANT REQUIREMENTS 2.5.1 Each of the above required low pressure CO2 systems shall be demonstrat'ed

! OPERABLE:

a. At least once per 7 days by:

~

1. Verifying'each1CO2 storage tank level;and pressure.

2. Visual inspection of each 002 storage tank's ancillary equipment.

b. At least once per 60 days by verifying that each valve (manual, power operated, or automatic) in the flow path is in its correct position.

c. At least once per 12 months by verifying:

1. The system valves and associated ventilation dampers actuate automatically i and manually upon receipt of a simulated actuation signal.

2. Flow from each nozzle.

2.5.2 If a low pressure CO2 system is determined inoperable during a surveillance or if the required surveillance frequency is exceeded, declare the system inoperable and return the system to OPERABLE status within 14 days or l

prepare and submit a special report to the Commission within the next 30 days per Technical Specification 6.9.2.
