- Criteria for determining number of failures and number of valid tests shall be in accordance with Regulatory Position C.2.e of Regulatory Guide 1.108, Revision 1, August 1977, where the last 20 and 100 tests are determined on a per diesel generator basis. For the purposes of this test schedule, only valid tests conducted after the Operating License issuance date shall be included in the computation of the "last 100 valid tests". Entry into this test schedule shall be made at the 31 day test frequency. Increased test frequency for one diesel generator 1 shall not affect the test frequency for the remaining diesel generator, even under the STAGGERED TEST BASIS criteria.
**This test frequency shall be maintained until seven consecutive failure-free demands have been performed and the number of failures in the last 20 valid demands has been reduced to one.
***For purposes of determining the required test frequency, the previous test ;
failure count may be reduced to zero if a complete diesel overhaul to 1 like-new conditions is completed, provided that the overhaul, including appropriate post-maintenance operation and testing, is specifically approved by the manufacturer and if acceptable reliability has been demonstrated. The reliability criterion shall be successful completion of 14 consecutive tests in a single series; 10 of these tests shall be in accordance with Surveillance Requirement 4.8.1.1.2a.4,5 and 4 of these tests shall include the fast loading requirement described in the double-asterisked (**) note to surveillance requirement 4.8.1.1.2a.5. If this criterion is not satis-fied during the first series of tests, any alternate criterion used to trans-value the failure count to zero may only be implemented with prior approval by the NRC.
#The valid failure to start the "A" Train Diesel Generator on 08/20/91 due.to the loss of the power dropping resistor in the governor circuitry is not to be counted toward the adjustment of test frequency for the "A" Train EDG. If the i
first 14 valid tests on the "A" Train EDG following the 08/20/91 failure do not result in a failure caused by the new power dropping resistor, the valid 08/20/91 failure is trans-valued to zero and this provision no longer applies. WATERFORD - UNIT 3 3/4 8-7 AMENDMENT NO. 23.71

Verifying average electrolyte temperature above the minimum for which the ! 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. m Table 4.8-2 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 specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the manufacturer's full charge specific gravity, ensures the OPERABILITY and capability of the battery. 9 WATERFORD - UNIT 3 8 3/4 8-2 AMENDMENT NO. 887 92

The diesel generator Surveillance testing performed once per 18 months during shutdown is in accordance with Regulatory Guide 1.108, Regulatory Position C.2. 1 l INSERT A l The maximum voltage limit in surveillance test 4.8.1.1.2.d.2 was increased to 5023 volts in response to NRC Information Notice 91-13: Inadequate Testing of Emergency Diesel Generators. A maximum voltage limit is provided to ensure that components electrically connected to the diesel generator are not damaged as a result of the momentary voltage excursion experienced during this test. , 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 450-1980, "IEEE Recommended Practice for Maintenance. Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations." Verifying average electrolyte temperature above the minimum for which the 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. Table 4.8-2 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 i 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 normal 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 specific gravity with an average specific gravity of all ; the connected cells not more than 0.010 below the manufacturer's full charge specific gravity, ' ensures the OPERABILITY and capability of the battery.

' REVIEWERS NOTE: The underlined text is new. The italicized text was proposed in a previous change-submitted by letter dated' July 7.1995. The Onsite Power System includes three 4.16 kV ESF buses (3A3-S, 3B3-5, and 3AB3-5). Power. for safety related loads is normally supplied by the non-safety related 4.16 kV buses (3A2 and 3B2) of the Offsite Power System. Should offsite power from either of these buses be lost, the Onsite Power System will receive power automatically from the appropriate diesel generator. Non-safety related loads will be automatically disconnected from the safety Onsite Power System. Each ESF bus (3A3-S or 383-S) is redundant to the other; each can supply sufficient power to its safety related loads to enable safe shutdown, or to mitigate the consequences of a design basis accident. The third bus, 3AB3-S, may be connected to either 3A3-S or 383-S, but never to both. Therefore 3AB3-S is not considered as a third, separate source of ESF power. The three ESF buses and their loads are tested as described below. Surveillance requirements 4.8.1.1.2.d.3 and 4.8.1.1.2.d.5 are the integrated testing requirements that demonstrate the as designed operation of the standby A.C. powr sources during loss of the offsite power source and during a loss of offsite power in conjunction with a Safety Injection Actuation Signal (SIAS). The testing verifles all actions encountered fra the loss-of-offsite power (LOOP), including shedding of the nonessential loads and the energizing of the emergency busses and respective loads fra the diesel generator, it further demonstrates the capability of the diesel generators to autmatically achieve the required voltage and frequency within the specified time. The requirement to verify the connection and energization of permanently connected loads and auto-connected loads is intended to satisfactor11y show the relationship of these loads to the diesel generators loading logic. ' Permanently connected loads are those loads that remain connected. k to the bus upon the bus deenergizing and are subsequently energized by the diesel generators. Auto connected 103ds are those loads that are disconnected fra the bus upon the bus deenergizing and are auto-connected through the automatic load sequencer. Surveillance 4,8.1.1.2.d.3b verifies the diesel generators capability to energize the shutdown loads and surveillance 4.8.1.1.2.d 5b verifies the diesel generators capability to energize the emergency loads. Shutdown loads are those loads required upon a LOOP (Re: FSAR Table 8.3.1). Emergency loads are those loads required upon a LOOP in conjunction with an SIAS. This testing verffles that in the event of a Design Bases Accident (DBA) coincident with a loss of offsite power. the diesel generators are capable of supplying the necessary power to Engineered Safety Features (ESF) systems so that the fuel, Reactor Coolant System (RCS). and containment design limits are not exceeded. Surveillance reauirement 4.8.1.1.2d.1 requires the verification at least once per 18 months of the diesel generators' ability to reject a load of greater than or equal to 498 Kw while specific voltage and frequency constraints are maintained. The intent of this Surveillance requirement is to ! require the diesel generator to reject the largest single load. The largest single load on the diesel generator is the Essential Chiller which requires 430 Kw under tornado / missile conditions. The difference between the specified 498 Kw load in the Surveillance requirement and the 430 Kw required by the actual largest single load is a margin of conservatism. A method of rejecting a load greater than or equal to 498 Kw utilizing the wet and dry cooling tower fans has been developed j and will satisfy the Surveillance requirement. The loading range for the diesel generators (4000-4400 Kw) as specified in surveillance requirements is eaual to approximately 90 to 100 percent of its continuous rating. This provides for a range to conduct testing without inadvertently overloading of the diesel generators. Inadvertent overloading creates unnecessary wear and mechanical stress that may adversely affect the reliability and longevity of the diesel generators. j}}
