HATCH NUCLEAR PLANT, UNITS NOS. 1 & 2 DOCKET 5 N05. 50-321 At10 50-366 INTRODUCTION
'By letters, as noted below, Georgia Power Company (GPC) propo. sed revisions to the Edwin I. Hatch Nuclear Plant (Hatch) Unit 2 Technical Specifications (TSs) as follows:
1.
Letter' dated April 5,1982, proposed to extend the time allowed to restore thermal power scram and control rod block trip setpoints to within allowable values; and 2.
Letter dated November. 10, 1982, proposed to correct an erronenin reference to a section of.the TSs.
By letters, as noted below, GPC proposed revisions to the TSs for both Hatch ~ Unit 1 and Unit 2 as follows:
1.
Letter dated June 11, 1982, as corrected by letter dated October 15, 1982, proposed to increase the minimum shift crew composition to conform with the requirements of NUREG-0737, Item I.A.1.3.2; and
.2.
Letter dated March 31, 1983, proposed to increase the frequency of independent audits. of both the emergency and security plans.
Our evaluation of these proposals and our conclusions are discussed below.
EVALUATION
. Restoration of Thermal Power Scram and Control Rod Block Trio Setooints.
By letter dated April 5,1982, GPC requested a change to the Hatch Unit 2 TSs to extend the time allowed for corrective actions to restore the Average Power Range Monitor (APRM), flow referenced, simulated thermal power scram and control rod block trip setpoints to within allowable values.
8403010120'840222 DR.ADOCK05000g m.
Present Technical Specifications require a reduction in thermal power if
}
APRM, flow referenced, simulated thermal power or control rod block setpoints that exceed allowable values are not brought back within these allowable values within two hours. The corrections are made by adjusting the control rod patterns and determining the. effects of the adjustments. This is an iterative process which is difficult to complete within two hours. The time limit specified in the liRC Standard Technical Specifications for making this correction is six hours. GPC proposes to extend the current two hour limit to six hours, making it consistent with the Standard Technical Specification limit.
We conclude that the proposed change is acceptable.
Correction of Error By letter dated November 10, 1982, GPC requested a change to the Hatch Unit 2 TSs to correct an error where Section 3.9.8 is incorrectly referenced in Section 3.5.4.b.2 as containing limits on refueling water level, while in fact, the referenced section actually regulates crane travel over the spent fuel pool. The correct reference, Section 3.9.10, " Water Level-Spent Fuel Storage Pool", will be. provided by the change.
Minimum Shift Crew Composition By letters dated June 11, 1982, and October 15, 1982, GPC proposed to modify Table 6.2.2-1 of both the Hatch Unit 1 and Unit 2 TSs to increase the minimum shift ccmposition requirements. GPC has subsequently informed us that it inadvertently listed two instead of three Non-Licensed personnel in the Table for the situation where one reactor is in Condition 1, 2 or 3 and there is no fuel in'the other reactor. GPC has orally informed us that this nurber should be three rather than two, and we have made this correction.
We have reviewed the proposed increases and found that the proposed minimun staffing numbcrs are consistent with the requirements of 10 CFR 50.54(m) ard with the numbers specified by NUREG-0737, Item I.A.1.3.2.
On this ba:'s, we conclude that the proposed changes are acceptable.
Frecuency of Audit of Energency and Security Plans By letter dated March 31, 1983, GPC proposed to nodify Section 6.5.2.8 of the TSs for. both Hatch Unit 1 and Unit 2 to' change the recuired frequency of independent audits of both the emergency and security plans from "at least once per. 24 months" to "at least once per 12 months". These proposed changes make these TSs consistent with the frequency of independent audits of the emergency and security plans as required by 10 CFR 50.54(t) and 10 CFR 73.40(d) and are acceptable.
EllVIRON!! ENTAL CONSIDERATION We have determined that the amendments do not authorize e chance in effluent
~
types or total amounts nor an increase in power level and wil1 not result in any significant environmental inpact.
Hhvino nade this determinatin'n, we have
~
- further-concluded that the amendments' involve an' action which is insignificant.
from'the' standpoint of environmental impact and, pursuant to 10 CFR 551.5(d)(4),
that an environmental _. impact statement or-negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of these amendments._-
CONCLUSION x
We have concluded, based on the considerations discussed above, that: -
(1) there-is ~ reasonable assurance that the health.and safety of the public.will not be endangered ~by operation in the proposed manner, and (2) such activities will-be _ conducted in compliance with the Commission's regulations and the
. issuance of these amendments will not be inimical.to the common defense and security or.to the health and safety'of the public.
