Grand Gulf Nuclear Station Unit 1 Docket No. 50-416 We have reviewed Sections 3/4.4.4, Chemistry; 6.8.4.c, Administrative Controls Post-Accident Sampling; 3.3.7.9, Fire Detection Instrumentation; 3.7.0.1, Fire Suppression Water System; 3.7.6.2, Spray and/or Sprinkler Systems; 3.7.6.3, CO Systems; 3.7.6.4, Halon Systems'; 3.7.6.5, Hose Stations; 2
3.7.6.6, Yard Fire Hydrants and Hydrants Hose Houses,' 3.7.7, Fire Rated Assemblies, and compared them to the Standard Technical Specification.
Based on our review, we conclude Section 3/4.4.4, Chemistry and 6.8.4.c, Administrative Controls Post-Accident Sampling are acceptable.
We recommend the following changes to the remaining sections:
1.
Page 3/4 7-28, paragraph 3.7.6.1 Action paragraphs' a. and b. - these paracraphs should be rewritten as follows:
a.
With one pump and/or one fire water storage tank inoperable, restore the inoperable equipment to OPERABLE status within 7 da'ys or provide an alternate backup pump or supply.
The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.
b.

By letter dated September 9, 1983, the applicant requested changes to the Fire Detection Instrumentation and Hose ' Station sections of the Technical Specifications.
Based on our review, we conclude that the changes to the Hose Station section reflect the as-b'uilt conditions in. the plant and therefore are acceptable.
We recommend the following changes to the Fire Detection Instrumentation Section of the proposed technical specification.
1.
Page 3/4 3-76, paragraph 3.3.7.9 - Action paragraphs a., b. and c. -
_ these paragraphs should be. rewritten as follows:
a.
With any, but not more than one-half the total in any fire zone, Functi'on A fire detection instruments shown in Table 3'.3.7.9-1 inoperable., r:e' store the ' inoperable instrument (s) to operable status within 14 days or within the next I hour establish a fire watch
. patrol to inspect the zone (s) with the inoperable instrument (s) at 1 east once per hour,.unless the i~nstrument(s) is' located inside the containment, drywell, or steam tunnel then inspect that cont
'+ zone at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> (or monitor the containment
- drywe, i s' team tunnel air temperatures at least once per hour at the locations listed in Specification 4.6.1.6).
b.
With more than one-half of the Function A fire detection instruments in any fire' zone shown in Table 3.3.7.9-1 inoperable, or with any Function B. fire detection instruments shown in Table 3.3.7.9-1 inoperable, or with any two or more acjacent fire oetection instruments.whown in Table 3.3.7.9-1 inoperable, within I hour establish a fire watch patrol to inspect the zone (s) with the inoperable instrument (s) at least once per hour, unless tne instrument (s) is located inside the containment, drywell, or steam tunnel then inspect that containment rene at least once per E hours (or monitor the containment air temperatu.re drywell and steam tunnel at least ence per hour at the le:atiens listed in Specification 4.6.1.6,).
