NUCLEAR REGULATORY COMMISSION W AaHINGToN, D.C. agL26 SAFETY EVALUATION BY THE OFFICE OF NVOLEAR REACTOR REGULATION
,RELATED TO AMENDMENT NO.171 TO TACILITY OPERATING LICENSE OPR 67 AND AMENDMENT NO.109 TO FAClllTY OPERATING LICENSE NPF 5 G10RGIAPOWERCOMPANY.ETAL.
EDWIN 1. HATCH NUCLEAR PLANT, UNITS 1 AND 2 DOCKET N05. 60 321 AND 50-366 1.0 -INTRODUCTION By letter dated August 20, 1990, Geotgia N w Company, et al., the licensee for the Edwin 1. Hatch Nuclear Plant, prc@osed changes to the Technical Specifica-tions (TSs) and Environmental Technical Specifications (ETSS) for Units 1 and 2.
The proposed changes would modify the TSs and ETSt for Units 1 and 2 as follows:
- 1. Change Unit 2 15 Table 3.2.2-1 to replace the master parts list (MPL) for items 1.f and 4.g.
- 2. (a) Change Unit 1 TS Table 4.2 2 to correct the spelling of ' Emergency
- under Reference-ho. 8.
(b)ChangeUnit2TSTable3.3.6.1-1tocorrectthemeasurementr$nge for the off-gas post-treatment monitors, and TS 4.6.6.1.1.d.3 to incorporate a plus/minus sign for the range of heat dissipated by the standby gas treatment subsystem heaters.
(c)_ Delete the list of Figures in the ETS Table of Contents for Units 1 and 2.
- 3. Change Unit 2 TS 3.8.2.5 and TS Table 3.8.2.6-1 to make editorial j
corrections.
2.0 Q ALVATION i
2.1'_ Proposed Change 1
-This proposed change to Unit 2 TS Table 3.3.2-1, ' Isolation Actuation
< Instrumentation," would make revisions that are editorial in nature.
It would j
correct the MPL numbers under Item 1.f. " Turbine Building Area Temperature t
-High,* and Item 4.g, "Supression-Pool Area Temperature Timer Relays." The specific MPL changes for.l.f would replace designators 2061-R001 through R004 to 2061 P001 through P004 and 1or 4 9 from 2E41 to 2E51.
The proposed change
'to 4 9 corrects a typographical error, while the proposed change to item 1.f reflects the change in indicator panels. These changes are acceptable because they do not affect plant opera. tion, and the safety-related equipment is not changed.-

2 2.2 proposed Change 2 These proposed changet to the Unit 1 and Unit 2 T$s end ETS$ would make revisions that are editorial in nature. The specific administrative changes proposed to provide clarity are as followst
.l Unit 1 Table 4.2 Correct the spelling of 'Energency* under Reference J
No. B.
1 Unit 2 Table 3.3.6.11-Correctthemeegurementrangeoftheoffgas pos}.treatgentmonitorsfrom10*g to 10* countspersecond(eps)to

10 to 10 cps.
Unit 2 Surveillance Requirement 4.0.6.1.1.d.3 Correct the range of heat dissipated by the standby gas treatment subsystem heaters from 18.5 4 1 5 kW to 18.5
- 1.5 kW.
J Units 1 and 2 ETS Table of Contents - Delete the litt of Figures in the ETS Table of Contents since Figure 5.21 is the only figure listed and it was deleted in Amendments 145 end 80 for Units 1 and 2, respectively.
These changes are found acceptable because they are considered editorial changes that do net effect plant operation or safety ard involve no physical changes to the plant.
d l
2.2 proposed Change 3 This proposed change to the Unit 2 TSs would make revisions that are editorial in nature. The specific administrati'fe changes proposed to provide clarity are j
as follows:
TS 3.8.2.5 Items a, b, e and d - Correct the word ' Circuit" to
- Breaker,*
and for item c, the breaker numbers 26 and 32 would change to 28 and 34, respectively.
Also, for Item d, the term, ' Compartment" would change to
' Frame
- Table 3.8.2.6 Relocate items c.3 and c.4 to the next page of the table and change the designation for the drywell cooling unit breakers from thermal magnetic breakers to magnetic only breakers.
Further, the secuential lettering for Type 6 and Type 7 devices would be corrected, anc throughout the tabic, changes would be made to reflect current equipment designation and to make the termit. ology consistent with other design documents.
These changes are found acceptable because they are considered editorial changes that do not affect plant operation or safety and involve no physical changes to the plant.
e$-
3.0 E_NVIRMMEhTAL CCNSIDERATION These amendments involvt changes in reavirements with respect to the installa-tion or use of facility components located within the restricted area as defined in 10 CFR Part 20 and changes in surveillance requirements.
The staff has determined that the amendraents involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Comission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public consnent on such finding.
Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issu6nce of the amendments.
4.0 CONCLLISION The Comission's proposed determination that the amenonents involve no significant hazards consideration was published in the Federal Register on October 31, 1990 (55 FR 45081), and the State of Georgia was consulted.
No public comments were received, and the $ tate ff Georgia did not have any coments.
We have concluded, based on the considerations discussed above, thats (1) there is reasoneble assurance that the health and safety of the public will not be endangered by operation in the proposed tranner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendments will nct be inimical to the common defense and security or to the health and safety of the public.
