Table 3.8-1 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level,. float voltage and specific gravity.

The limits for the designated pilot cells float voltage and specific gravity, greater than 2.13 volts and 0.015 below the manufacturer's full charge specific gravity or a battery charger current that had stabilized at a low value, is .

characteristic of a charged cell with adequate capacity. The nomal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not more than 0.020 below the manufacturer's full charge specificgravitywithanaveragespecificgravityofalltheconnectedcells not more than 0.010 below the manufacturer s full charge specific gravity, ensures the OPERABILITY and capability of the battery. ,

.

Operation with a battery cell's parameter outside the normal limit but" within the allowable value specified in Table 3.8-1 is permitted for up to 7 days. During this 7 day period: (1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than 0.020 below the manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less than the safety margin provided in sizing; 3) the allowable value for an individual cell's specific gravity, ensures that an individual cell's specific gravity will not be more than 0.042 below the manufacturer's full charge -

specific gravity and that the overall capability of the battery will be maintained within an acceptable limit; and 4) the allowable value for an individual cell's float voltage, greater than 2.07 volts, ensures the battery's capability to perform its design function. .

Safety Analysis Beaver Valley Power Station i Proposed Technical Specification Change l BV-1 Change No. 171 l BV-2 Chanae No. 32  !

Description of Amendment Request: The proposed amendment would l modify the diesel generator surveillance requirements to reflect the j McGuire Technical Specifications (TS) and Draft Revision 5 of the i 9tandard Technical Specifications (STS) recommended by the NRC for '

sampling and analysis of diesel generator fuel oil. j specification 3.8.1.1 has been revised by adding note (1) to clarify l the Action requirements when the diesel generators are inoperable as a result of surveillance requirements 4. 8.1.1. 2.d. 2 or 4. 8.1.1. 2. e.

These surveillance requirements verify the quality of the fuel oil in the storage tanks on a periodic basis and in accordance with Regulatory Guide 1.137 Regulatory Position C.2.a, the fuel oil may be l replaced in a short period of time (about a week) when the fuel oil i does not meet the specification requirements. The intent of the surveillance requirements is to ensure the fuel oil satisfies the quality specifications, therefore, note (1) has been written to allow up to 7 days to correct the out of specification condition whether this involves replacing the fuel oil or another suitsble method.

Surveillance requirement 4.8.1.1.2.a.3 has been deleted for both units. The fuel oil sample verification requirements will be satisfied by surveillance requirements 4.8.1.1.2.c, d and e.

BV-1 surveillance requirement 4.8.1.1.2.c has been added to require temoval of accumulated water (1) from the day tank at least once per 31 days and after each operation of the diesel where the diesel has i operated for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or more, and (2) from the fuel oil storage tank, at least once per 92 days. This surv3111ance requirement is consistent with the BV-2 requirement, however, it differs from the McGuire requirement in that the McGuire TS required removal of accumulated water from the storage tank once per 31 d'ys. The BV-2  ;

'

TS requires romoval of accumulated water once per 92 days. This quarterly surveillance is consistent with a clarification in Draft '

Revision 5 of the Standard Technical Specifications (STS) which

'

provides for a frequency of once per 92 days (or once per 31 days (if the groundwater table is equal to or higher than the bottom of the I fuel oil storage tanks)). This also reflects the guidance provided in Regulatory Guide 1.137 " Fuel-Oil Systems For Standby Diesel Generators," Regulatory Position C.2.d which states " Accumulated condensate should be removed from storage tanks on a quarterly basis or on a monthly basis when it is suspected or known that the groundwater table is equal to or higher than the bottom of buried storage tanks." The groundwater table averages 30 feet below the surface as described in BV-1 UFSAR Section 2.3.2 and Figure 2.3-3; and BV-2 UFSAR Section 2.4.13 and Figure 2.4-17, therefore, the quarterly surveillance is applicable.

No Significant Hazard Evaluation Beaver Valley Power Station Proposed Te.,hnical Specification Change BV-1 Change No. 171 BV-2 Change No. 32

'

Basis for proposed no significant hacards consideration determination: The Commission has provided standards for determining whether a significant hazards consideration exists in accordance with 10 CFR 50.92(c). A proposed amendment to an operating license for a facility involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety.

The proposed changes do not involve a significant hazard consideration because:

1. The diesel generator fuel oil surveillance requirements have been revised to reflect Draft Revision 5 of the Stundard Technical Specifications (STS) and the McGuire Technical Specifications (TS). Specification 3.8.1.1 has been revised by adding note (1) to clarify the Action requirements when the diesel generators are inoperable as a result of surveillance requirements 4.8.1.1.2.d.2 or 4.8.1.1.2.e. These surveillance requirements verify the quality of the fuel oil in the storage tanks on a periodic basis and in accordance with Regulatory Guido 1.137 Regulatory Position C.2.a, the fuel oil may be replaced in a short period of time (about a week) when the fuel oil does not meet the specification requirements. The intent of the surveillance requirements is to ensure the fuol oil satisfies the quality specifications, therefore, note (1) has been written to allow up to 7 days to correct the out of specification condition whether this involves replacing the fuel oil or another suitable method. Surveillance requirement 4.8.1.1.2.a.3 has been deleted for both units. These fuel oil sample verification requirements will be satisfied by surveillance requirements 4.8.1.1.2.c, d and e. BV-1 surveillance requirement 4.8.1.1.2.c has been added to require removal of accumulated water (1) from the day tank at lesst once por 31 days and after each operation of the diesel where the diesel has operated for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or more, and (2) from the fuel oil storage tank, at least once per 92 days. This is consistent with the DV-2 r equirement,- Draft Revision 5 of the STS and Regulatory Guide 1.137 " Fuel Oil Systems For Standby Diesel Generators."

Surveillance requirement 4.8.1.1.2.d has been added to the BV-1 TS to reflect the McGuire requirements for sampling and testing new fuel oil. This surveillance requirement has also been incorporated in the BV-2 TS to replace surveillance requirement 4.8.1.1.2.d and effectively updates the ASTM standards referenced to later versions.

to ensure adequate fuel oil quality is available for diesel ,

generator operation, thercfore, the probability or consequences of an accident previously evaluated will not be increased.  ;

2. The proposed changes incorporate additional requirements for BV-1 and update the BV-2 fuel oil sampling and quality verification .

requirements. These changen are consistent with Draft Revision 5 of the STS and the McGuire TS which provide an acceptable basis i for adequate fuel oil surveillance. Therefore, the proposed i changes will not create the possibility of a new or different i kind of accident from any accident previously evaluated.

3. These changes are consistent with the accepted criteria for sampling, testing and verification of diesel generator fuel oil '

quality. The proposed changes will not affect any of the plant setpoints or margins to the accident analysis limits. Therefore, the proposed changes will not involve a significant reduction in ,

'

l the margin of safety of the plant.

'

Therefore, based on the above considerations, this amendment does not involve a significant hazard. j
