1.0 INTRODUCTION
10, 1990, as supplemented January 21 and December 16, By letter dated January 1991, and March 5, 1992, the Georgia Power Company, et al. (the licensee),
submitted a request for changes to the Edwin 1. Hatch Nuclear Plant, Units 1 dDd 2, Technical Specifications (TSs). The requested changes would change TS 3.9/4.9, " Auxiliary Electrical Systems," (Unit 1) and TS 3/4.8.1, "A.
C.
Sources," (Unit 2) regarding emergency diesel generator (EDG) testing.
The proposed change', are intended to eliminate discrepancies between the plants' TSs and Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units i
Used As Onsite Electric Power Systems At Nuclear Power Plants," and to conform to the guidance contained in Generic letter (G.L.) 84-15, " Proposed Staff Actions to improve and Maintain Diesel Generator Reliability," dated July 2, 1984. The January 21, 1991, letter, in response to the staff's December 14, l
1990, request, the December 16, 1991, and the "HL-2075, Forwards Response to NRC 901218 Request for Addl Info Re 900110 Application for Amends to Licenses DPR-57 & NPF-5, Changing TS to Revise Testing Requirements on [[system" contains a listed "[" character as part of the property label and has therefore been classified as invalid.s|March 5, 1992, letter]]s provided additional ano clarifying information and proposed additional changes to the i
plants' TSs for EDG testing that did not change the initial proposed no significant hazards consideration determination.
2.0 EVALUATION The asterisks that appear in the revised TS pages are discussed separately from the text later on in this section.
I Change IA:
In TS 4.9.A.2.a.1 (Unit 1), add:
A steady-state voltage of 4160 1 420 volts and a steady-state frequency of 60 t 1.2 Hz will be maintained.
in TS 4.9.A.2.a.2 (Unit 1), add:

The above changes are proposed to add acceptance criteria for CDG voltage and frequency following the guidance contained in G.L. BA-16. These changes add consenatism to the TS and are, therefore, acceptable.
3 C',ynge 10:
In TSs 4.8.1.1.2.d.5.b and 4.8.1.1.2.d.B.h (Unit 2), add:

Also the wording of the Unit 1 TSs is made consistent with the Unit 2 TSs. These changes add conservatism and censistency to the plants' TSs and are, therefore, acceptable.
Change 10:
In TS 4.9. A.2.a.1 (Unit li, delete:
During the generator test, the starting air compressor shall be checked for operation and for its ability to. recharge the air system and substitute:
Verify the pressure in both diesel air start receivers to be 2 225 psig.
The above change is proposed to add consistency between both uMts' 15s.
Also, this change represents a more definitive e,uie ment. On this basis, the NRC staff finds it acceptable.

to 2775-2825 kW*
The asterisk refers to a new footnote that reads:
Momentary _._ variations outside this band shall not invalidate the. test.
The above loading changes represent higher loading than those currently contained in the Unit 2 TSs, are more conservative, and are, therefore, acceptable. Also, the new Unit 1 TSs are identical r
to the modified Unit 2.TSs. represent added conservatism, and'are therefore, acceptable.
Change 3:
InTS4.8.1.1.2.d.3(Unit 2), delete:

this would be either the 20 or 2D RHRSW pump at rated i
flow. During these load rejection tests, the diesel 1
generat r shall not exceed the nominal speed plus 757 of the difference between nominal speed w d the
-overspeed trip setpoint, or 15% above nominal speed, whichever is lower.
In TS 4.8.1.1.2.d.4 (Unit 2), after the words:
t reject a load of modify the original wording to read:
at least 2775 kW without tripping. The generator voltage shall not exceed 4800 volts during and h 110 wins the load rejection.
In TS 4.9.A.2.a (Unit 1), add the following as a.4 and a.$,
respectively At least once per 18 months during shutdown, verify the diesel generator capability to reject its largest single shutdown (emergency) load while maintaining voltage at 4100 t 420 volts.
For diesel genert,hr IA, this would be CS [ core spray] pump 1A at rateo f'ow.
For diesel generator IB, this would be either the IC or 2C Residual Heat Removal Service Water (RHRSW) pump at rated flow.
For diesel generator IC, this would be CS pump 1B at rated flow.- During the load rejection test, the diesel generator shall not exceed the nominal speed plus 75% of the diffwence between nominal speed and the overspoed trip setpoint,-or 15% above nominal speed, whichever is less.
At least once per 18 months during shutdown, verify ~
diesel generator capability to reject a load of at least 2775 kW without tripping. The generator voltage 4
shall not exceed 4800 volts during and following the load rejection.
The above changes to the Unit ? TSs follow the guidance contained in G.L. 84 15 for partial and full load rejection I
testing and are, therefore, acceptable. Also, the.new TSs added for Unit I are similar to the modified Unit 2 TSs, represent added conservatism, and are, therefore, acceptable.

. Change 4:
At the end oi TS 4.8.1.1.2.d.9 (Unit 2), add "*"" that refer $ to the following new footnote:
If the diesel generator fails this test, a retest may be performed after the diesel generator has been operated for 2 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 2 2565 kW.
In TS 4.9.A.7 (Unit 1), add the following as A.7.b.2:
Within 5 minutes after completing the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> load test specified in Surveillance Requirement 4.9 a.2.a.6, repeat Surveillance Pequirement 4.9 A.7.b.1 with a simulated loss of offsite power start signal and ruti the diesel for at least 5 minutes while loaded with shutdown loads.* This test is to be performed every 18 months.
Also, renumber existing TS 4.9.A.7 b.2 as 4.9 A.7.b.3.
The above asterisk refers to the following new footnote:
li *he diesel generator falls this test, a retest may be perTormed af ter the diesel generator has been operated for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> at 12565 kW.
Originally the Unit 2155, but not the Unit 1 TSs, required that a loss of offsi'.e power test be performed irinediately f ollowing the EDG 24-hour test.
Because the revised T$s added for Unit 1 are the same t the Unit 2 TSs and represent added conservatism, we find the c'ennge acceptable.
The new isotnote added to the TS is consistent with the current staff pcsition that the whole 24-hour test does not need to be repeated if the diesel just failed the loss of offsite power test; only the loss of offsite power test needs to be repeated after the diesel generator has been operated for > 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at full load.

Each of the five diesel generators is provided with a storage tank and a day tank.
The 33,000 gallons required to be maintained in each cf the fuel oil tanks represents a total volume of cil suf ficient to operate any four diesel generators at 3250 kW for a period of 7 days. This is based on a conservative expected fuel consumption of 240 gallons per hour per engine.
The onsite fuel capacity will last longer than the time it would take to replenish the onsite supply from offsite sources (which is ( 7 days).
Valving is available so that fuel oil can be transferred between fuel oil storage tanks.
However, administrative controls shall be in place to limit long-term total diesel generator load to ( 13,000 kW and to limit individual diesel generator loading to < 3250 kW.
The above changes represent an increase in the amount of diesel fuel stored in the diesel fuel storage tanks and clarify'the bases for the amount of fuel required. Because these changes add conservatism to the plants' TSs, we find them acceptable.

At the end of the TS 4.8.1.1.2.d.3 (Unit 2), add an "*" that refers to the following new footnote:
For the 18 diesel generator, a single partial load rejectice test every 18 months will satisfy the requirement.i cf Unit 1 Specification 4.9.A.2.a.4-and Unit 2 Specification 4.8.1.1.2.d.3.
At the end of TS 4.8.1.1.2.d.4 (Unit 2), add an "*" that refers to the following new footnote:
for the IB dieci generator, a single full load rejection test every 18 months will satisfy the requirements of Unit 1 Specifi-cation 4.9.A.2.a.5 and Unit 2 Specification 4.8.1.1.2.d 4 At the end of the second sentence in TS 4.8.1.1.2.d 9_(Unit 2),
add a "**" that refers to the following new footnote:

- <*o 15 -
For the 10 diesel generator, a single 24-hour load test every 18 months will satisfy the requirements of Unit 1 Specifi.
cation 4.9.A.2.a.6 and Unit 2 Specification 4.8.1.1.2.d.9.
The above thenges are intended to reduce the unnecessary double testing of the swing EDG 10 during the 18 month inspection, 24-hour load test, and parti 61 and full load rejection tests required by the current Unit 1 and Unit 2 TSs. These changes meet the intent of the recorrnendations contained in G.L. 84-15 and are, therefore, acceptable.
Change 70:
In the original TSs 4.9.A.2.a.1 and 4.9.A.2.a.2 (Unit 1), replace the "*" with "**" that refers to the original footnote:
"Homentary variationt..."
This is an editorial change related to Change 7C. Therefore, it is acceptable.
Chance 8:
Delete the original TS 4.8.1.1.2.e (Unit 2) and renumber original TS 4.6.1.1.2.f (Unit 2) as 4.8.1.1.2.e.
TS 4.8.1.1.2.e currently requires that every 5 years the EDGs be started at least 5 times with the air start receivers pressurized to 225 psig and their compressors secured.
Deleting this TS will reduce unnecessary EDG testing and is consistent with the intent of G.L. 84-15 and the latest staff position. On this basis, the NRC staff finds this change acceptable.
Change 9:
In the Bases 3/4.8 (Unit 2) on page B 3/4 8-1 at the end of the sixth paragraph, add:
and Generic Letter 84-15. " Proposed Staff Actions to improve and Maintain Diesel Generator Reliability," July 2, 1984 This change is editorial in nature and reflects the current staff requirements for EDG testing. On this basis, it is acceptable.
