RSSP-2.2 DIESEL GENERATOR IOAD AND SAFEGUARD SEQUENCE TEST
1.0 PURPOSE
To provide instructions for alignment of valves and equipment to be operated during performance of the Diesel Generator Load and Safeguard Sequence Test.
1.2 To provide instructions for verification that the Diesel Generator and all associated Safeguazd Equipment will perform their intended functions.
2.0 TEST REQUIREMENTS:
2.1 This test is to be performed during each Reactor Shutdown for refueling.
2.2 Each Diesel Generator must demonstrate its'bility to start automatically and assume its'ssociated Safeguard Equipment sequence loading schedule upon an actual loss of all normal A.C. station service power supplies together with a simulated Safety Injection Signal.
2.3 Each Diesel Generator must start and close into its respective Safeguard buses in approximately 10 seconds from the initial starting signal as evidenced by traces on a suitable recorder.
2.4 The safeguard Train A (Generator A-Safeguard Buses 14 6 18) loading from the initiation of the A Diesel Generator starting
, sequence, signal to the closure of 52/R.H.R. 1A (R.H.R. Pump lA Breaker) shall be 20 seconds or less.
2.4.1 Full loading time of Train A, from the initiation. of the A Diesel Generator starting signal to the closure of 52/MAFPIA (Motor Auxiliary Feedwater Pump Breaker) shall be 40 seconds or less.
2.5 The safeguard, Train B (Generator B-Safeguard Buses 16 R 17) loading sequence, from initiation of the B Diesel Generator starting signal to the closure of 52/R.H.R. 1B (R.H.R. Pump 1B Breaker) shall be 22 seconds or less.
2.5.1 Full loading time of Train B, from the initiation of the B Generator starting signal to the closure of 52/MAFP 1B (Motor Auxiliary Feedwater Pump Breaker) shall be 42 seconds or less.
2.6 Safety injection pump breakers (52/SIP 1C1 6 1C2) will have a differen-tial time of approx. 2 seconds, not less than 1.5, with 52/SIP1C1 being the longest..
2.7 Adjustments to bzeaker closuze timers (with the exception of 52/CSP lA 6 1B and 52/SIP 1A R 1B) may be made to ensure the above time limita=
tions using Proceduze RSSP-2.7.
Ai7OC C ~ C ~ C NOTE: Tndividual timer settings must not be adjustd such that the associated equipment starts mithin less than 3 seconds of the equipment preceeding it.
NOTE: The actual time involved for complete train actuation must be considered in relationship to the Plant's "Final Facility Description and Safety Analysis Report". Section 6, page 6.2-29 and Section 8, Table 8.2-4.
2.8 To verify that the Containment Spray Pumps are capable of automatically starting during the Safeguard sequence.
2.9 Verification of the following valve operations:
2.9.1 MOV 871A starts to close in 3.5 seconds (+ 1 second) upon failure of 1B SIP to start, after loss of Bus voltage and receipt, of S.I. signal.
2.9.2 MOV 871B starts to close in 3.5 seconds (+ 1 second) upon failure of IA SIP to start, after loss of Bus voltage and receipt of S.I. signal.
a 2.9.3 Spray additive valves HCV-836A and HCV-836B open in 2 minutesq+su seconasy after receipt of their respective trains'ontainment spray sz.gnal.
2.9.4 Service water isolation valve closure upon receipt of coincident loss of normal plant A-C service and Safety Injection Signal.
NOTE: As only one Safeguard train is checked at a time only six valves will close with each train test.

4.0 INITIAL CONDITIONS:
4.1 The plant is being maintained at cold or refueling shutdown status.
All concerned valves and equipment must be available for use during this test (e.g. No. safeguard valves or pumps can be held for maintenance and/or repair, with the exception of those valves which are required to be main-tained closed for test).
4a3 Only one Safeguard train will be operated at a time, D.C.
control voltage will be removed from the train not being tested.
4.4 The Residual Heat Removal System is aligned to the Reactor Coolant Loop for core decay heat removal.
NOTE: RHR flow will be interrupted briefly with the testing of each Safeguard train.
4.5 If system status require's the operation of.a component cooling water pump, the running pump will be selected opposite to the Safeguard train).
4a6 The Four inch service water cross tie valves in the diesel rooms will be open on each Service Mater loop. A service water pump opposite to the loop being tested will be in operation, and will not be removed from service until after the selected S.V. pump on the Safeguard train being tested has been started.
4.7 A temporary city water supply shall be connected to the "In Service" Instrument and House Service air compressors to ensure no loss of cooling water during test.
4a8 Plant conditions are such that containment ventilation isola-tion can be tolerated during performance of test (approximately 10 minutes with each Safeguard train operation).
4.9 Pro'cedure steps, alignment, data verification and restoration of equipment need not necessaiily be performed in the order listed. Deviation from the listed order of steps will be under the cognizance of the test co-ordinator.
4.10 SPECIAL EQUIPMEVZ 4.10.1 >iulti pen recorder and/or events marker used for monitoring the Safeguard Bus voltages and the operations of the Safe-guard train equipment.
TYPE EQUIPMENT USED:
DATE CALIBRATED:
4.11 Undervoltage relays for 480 Volt Buses 14, 16, 17, and 18 have been calibrated and timed by Relay Dept. prior to start of this test.
Lead Test personnel are qualified in accordance with
(}C"1104.
4.13 Ginna Station Test Tag Control Program, A-48 shall be utilized as required.
5.0 PRECAUTIONS
5.1 Sufficient quantities 'of diesel fuel is available for one hour operation of Diesel Generator plus that inventory which is necessary to satisfy plant Technical Specifications.
5.2 Residual Heat Removal Pump will be left in service until just prior to the initiation of the Safety injection signal.
5.3 Ensure that a flow path is provided from the Refueling Water Storage tank to the Reactor vessel (HOV 856 and RHR system).
5.4 In the event that a hazardous operating condition should develop the 60 second delay of Safety Injection reset may be defeated by resetting the Safety Injection relays SF-1 and SF-2 in the relay room (timer setting turned to zero). Control board reset 'may then be effected.
6.0 INSTRUCTIONS
