OFF~NORMAL OPERATING PROCEDURE NUMBER 2-0030130 REVISION 0 3 ~ 0 AUT(MATIC ACTIONS 3.1 The turbine generator will trip with EITHER A Turbine Trip Signal OR A Reactor Trip Signal 3.2 The reactor will trip with EITHER A Reactor Trip Signal OR A Turbine Trip Signal Power is
> 15X 3.3 Atmospheric Dumps and/or SBCS actuate following a trip or runback.
3.4 Plant electrical auxiliaries transfer from auxiliary to SU transformer.
3.5 Turbine trip on Hi S/G level will also close 100X feedwater bypass valves.
3.6 S/G level
< 34X initiates auxiliary FW auto start.
If the conditions for a reactor trip are present and the reactor has not tripped, proceed IMMEDIATELYto EP 2-0030132, Anticipated Transient Without a Scram (ALAS).
S
OFFWORMAL OPERATING PROCEDURE NUMBER 2-0030130 REVISION 0 4.0 IMMEDIATE OPERATOR ACTIONS 4.1 Verify all applicable automatic actions.
4.2 Manually depress reactor trip PB on RTGB 201 and 204.
4-3 Manually depress turbine trip PB on RTGB 201.
4-4 Verify reactor trip bkrs are open.
4.5 Verify all full length CEA s are fully inserted.
4.6 Verify all turbine control valves are closed.
4.5 If more than one CEA is NOT fully inserted, initiate emergency boration.
4.7 Verify gen bkrs are open (24(%40349)
(24(%03520) 4.8 Close reheater block valves MV-08-4, 6,
8, 10.
4.9 Verify that aux pwr has transferred to the S/U trans former.
OR DG 2A and/or 2B running breakers 20211 and/or
'0401 closed 4.10 Verify main feedwater feed 5% through 15%, values OR In the event of a COMPLETE los s of offsite powe r, refer immediately to Blackout Operation, 2-0030140.
Initiate Auxiliary FW
OFF~NORMAL OPERATING PROCEDURE NUMBER 2-0030130 REVISION 0 4o 0 IMMEDIATE OPERATOR ACTIONS 4.11 Verify that T avg is being maintained at 532 F by SBCS or atmospheric dumps
~
- 4. 12 Consult Break Diagnos tic Chart (Fig.
- 1) and determine if another emergency procedure is required'f so, refer 1MMEDXLTELYto that procedure.
If not, refer to subsequent actions for this procedure.
OFFmlORMAL OPERATING PROCEDURE NE18ER 2-0 30 30 REVISION
OFF~VORMAL OPERATING PROCEDURE NRfBER 2-0030130 REVISION 0 5o 0 SUBSEOUENT ACTIONS CAUTION If trip was caused by High Pressurizer
- Pressure, ensure the PORV's are closed or isolate manually when pressure
<2300 psig CHECK 5.1 Place the feedwater bypass valves in the "auto" position to maintain no load levels.
CAUTION Do not overfeed the S/G's.
This could cause T avg to go below 532oF and thermal shock the S/G's.
5.2 If the emergency diesels are running, start both motor driven aux fd pumps and maintain S/G level 5.3 If both the S/G feed pumps and motor driven auxiliary feed pumps are inoperable, then start steam driven auxiliary feed pp CATION Feed should be diverted from any S/G showing abnormally low steam pressure or high feed flow.
5.4 Verify przr level is being returned to setpoint by auto control of charging pumps and letdown control valves 5-5 Verify przr pressure is being controlled automatically by the heaters and spray valves
OFFNORMAL OPERATING PROCEDURE NRfBER 2-0030130 REVISION 0 5.0 SUBSE VENT ACTIONS (Cont. )
CHECK 5.6 If steam pressure cannot be aaintained above 800 psig, close MSIV's or atmospheric dump valves, cs appropriate, to avoid excessive cooldown and depr essur iza tion of the RCS.
5.7 Verify shutdown margin. If it is below tech
- spec, emergency borate 5.8 As the turbine slows down, verify the bearing oil pumps start as follows:
5.8.1 AC bearing oil pump and seal-oil backup pumps start together 9 11-12 psig 5.8.2 Emergency D.C. oil pump 8 10-11 psig 5.8-3 Bearing oil lift pump starts when turbine reaches 600 RPM HOTK:
If any of the above pumps fail to start, manually start.
5.9 Verify turning gear motor is operable prior to reaching 0 RPM 5.10 Verify 9 0 RPM the turning gear engages to engage it manually 5.11 Place turbine drain selector to OPEN
OFF~RORMAL OPERATING PROCEDURE NlÃBER 2-0030130 REVISION 0 5.0 SUBSE UENT ACTIONS (Cont.)
CATION Do not isolate steam to gland seals as long as condenser vacuum is maintained.
5.12 Reduce bearing oil temperature to 90oF 100oF In the event the condenser is not available, evaluate condensate storage tank inventory-CHECK 5.13 If it is unsafe to maintain the plant in.hot standby condition; bring the unit to cold shutdown per OP 82-0030127 5.14 If immediate recovery and return to power is planned, canaence CEA block circuit check, if required (see OP 82-0030122 Para.
- 8. 6)
CAUTION If RCP s have tripped, they may be restarted ifit has been confirmed that a lock has not occured, pump services CAN be restored and RCS pressure-temperature conditions permit restart.
OFF~IORM OPERATING kK(X E REVISION 0
, i 6 0 PURPOSE/DISCUSSION This procedure provides the entry to" a sequence of events that will lead to the safe termination of any of the emergency events considered for our plant.
The first few immediate actions verify that all has performed as it should.
The operator verifies CEA's in, or if not, is referred to the ALAS procedure.
He then verifies off-site power and if it is not available, he is referred to the Blackout Procedure.
He then scans a
Diagnostic Chart and, if necessary, is directed to the appropriate emergency procedures.
Each of these emergency procedures will provide specific instructions for the particular circumstances and verify adequate core cooling, or if not, refer to the operator to the inadequate core cooling procedure.
If no emergency conditions exist, the operator continues to the subsequent
- actions, which guide him to a safe shutdown and preparation for return to power, if conditions warrant.
