SUBJECT:

MILLSTONE NUCLEAR POWER STATION, UNIT NO. 3 - REVISION TO TECHNICAL SPECIFICATIONS BASES (TAC NO. MA4866)

Dear Mr. Necci:

By letter dated February 12,1999, Northeast Nuclear Energy Company (NNECO) provided the NRC with changes to Technical Spoofications (TS) Bases Section 3/4.8, "A.C. Sources, D.C. Sources, and Onsite Power Distribution." NNECO provided the TS Bases page to the NRC forinformation only.

As you are aware, the TS Bases'are not part of the TS as defined by 10 CFR 50.36. Changes to the TS Bases may voluntarily be made in accordance with the provisions of 10 CFR 50.59.

Should the proposed change. involve'an unreviewed safety question pursuant to 10 CFR 50.59(a)(2), or involve a change in the interpretation of implementation of the TS (i.e.,

constitute a TS change), then the proposed change is to be provided to the staff pursuant to

' the provisions of 10 CFR 50.59(c) and 10 CFR 50.90 for prior NRC R. view and approval.

The TS Bases you provided are hereby returned to you and should be inserted in the TS to ensure the NRC staff and NNECO have identical TS Bases pages. The staff did not perform i

an evaluation of your TS Bases revisions and staff concurrence with the revisions is not implied by this letter. The staff may review the evaluations that support these TS Bases revisions during the next inspection of Millstone Unit 3's implementation of 10 CFR 50.59.

Sincerely, j

ELECTRICAL POWER SYSTEMS BASES' A.C. SOURCES.'D.C. SOURCES. and ONSITE POWER DISTRIBUTION (Continued)

' The Surveillance Requirement for demonstrating the OPERABILITY of the station batteries are based on the recommendations of Regulatory Guide 1.129,

" Maintenance. Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February 1978, and IEEE Std 450-1975 & 1980, "IEEEl Recommended Practice for Maintenance, Testing,. and Replacement of Large Lead Storage Batteries for Generating Stations and Substations." Sections 5 and 6 of IEEE Std 450-1980 replaced Sections 4 and 5 of IEEE Std 450-1975, otherwise the balance of IEEE Std 450-1975 applies.

Verifying average electrolyte temperature above the minimum for which the l

battery was sized, total battery terminal voltage on float charge, connection resistance values, and the performance of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates, and compares the battery capacity at that time with the rated

-capacity.

Tthe 4.8-2a 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, l

is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 l

volts and not more than 0.020 below the manufacturer's full charge' specific l.

gravity with an average specific gravity of all the connected cells not more than O.010 below the manufacturer's full charge specific gravity, ensures. the l

OPERABILITY and' capability of the battery.

1 Operation with a battery cell's parameter outside the normal limit but within j

the allowable value specified in Table 4.8-2a is permitted for up to 7 days.

During this 7-day period: (1) the allowable values for electrolyte level ensures l

no physical. damage to the plates with an sdequate electron transfer capability; (2) the allcwable value for the average specific gravity l

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 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained 31 thin 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.
