1.1 Any Ala:n on Reactor Trip Firs: Ou: Panel.

1.2 All rod bo=om lights are illuminated.

1.3 Nuclear Ins =umancation 'm*4 r= ting a rapid decrease in Nau:ron fluz.

I 2.0 Immediate Action 2.1 Automatic 2.1.1 All rods drop into cora.

2.1.2 Turbina-<.anarator trip.

2.1.3 Feedvatar Isola ion when Tavg decrasses to 564*F.

2.1.4 Steam Dumps Arm-Act':.ata and/or Main Staam PORV lift.

2.2 Manual NOTE: If Reactor Power does not decrease rapidly and con =ol rods are not insertad, this is an "Anticipa:ad Transian: Without Scram" avant.

2.2.1 Verify Rasc:or Trip, if not tripped:

2.2.1.1 N=="='17 trip reactor.

2.2.1.2 If reactor trip has not ya: occu=ad, manually =1p the MG sa: Skrs. locally.

2.2.1.3 If reactor =1p has not yet occu=ad, immediately ac:ua e saf ary injection 2.2.2 Verify Turbina Ganarator Trip if not =irped:

2.2.2.1 d=="*" y crip turbine from Con =ol Room or locally at tha :urbina.

2.2.2.2 If turbine =ip cas not yet occu=ad, open ganarator breakars, placa DEE Control in manual and close the Governor Valves in fas: action.

! 2.2.2.3 If Turbina Trip has not yet occu= ad, close the MSIV's.

2.2.3 Verify Toadwater Isolation when Tavs decreases to <564*F.

l I 2.2.4 Verify Steam Dumps a:n-actuata and/or Main Steam PORV's operata

>1125 psig.

2.2.5 Secure all boroc dilution operations.

3.0 Subsequent Action CAUTION: Do not placa systems in manual unless misoperation in automatic is l

l apparent. If any syrstem is placed in manual, make frequent checks 1

1 for prepar operation.

3.1 If any pressurizar PORV's open on high pressurizar pressure, ensure ressating at 2315 psig decreasing.

NC""E : If PORV f ails to close and pressure is less han 2315 psig, i

close the associated PORV isolation valves.

l t

3.2 Ensure the CA System flow to Steam Generators. If not, manually start the uotor driven CA Pumps.

NOTE: If the CA Pumps receive an auto-start signal depress the Train "A" and Train "E" CA Modulating Valves Rasets in order to regulate flow to the steam generators.

3.3 verify no-load P:R level (25%) and Pressure (2235 psig) are restored and maintained. Verify charging and letdown flow normal. ,

1 3.4 Verify Tave is maintained >557*? and <562*F. l 1

3.5 verify Steam Generator levels are in he narrow range and S/G pressures are 1090 psig.

3.6 Announce occurrance over plant paging system.

3.7 Note the cause of the trip on the first out panal before resetting the alarm.

3.8 If all rods are not fully inser ad, borate 150 ppm for each rod not inserted per OP/1/A/6150/09 (Boron Concen=ation Con =c1).

3.9 Transfer NR-45 to one source use charmal and one intermediate range h a' for indication. Ensure a negative period and decaying count race.

3.10 When the ca;:se of the trip haa been determined, withdraw the shutdown banks per OP/1/A/6150/08 (Rod Control).

3.11 Turn Turb Gen Voltage Regulator switch to "Off".

3.12 Sclect "Raset" on the Moisture Separator bhanter Panel.

3.13 Transfer Auz. Sramm Supply to Main Stean by opening 1AS-12 (Un::.t 1 Ms.

Sta. to Aux. Stm. Bdr. Con =ol Inlet Isolation) and close 1AS-9 (Unit 1 "C" E=. Bleed to Aux. Scm. Bdr. Isolation) .

3.14 Transfer steam dump control to the " Pressure" mode and adjust controller as necessary to maintain Tave 557*T (approximately 1090 psig) .

l CAUTION: Ensure Primary and Secondary Systems have stabilized before going to pressure mode.

3.15 Place Auto Start Defeat switches of Aux. Feedwater Pumps A & B to " Defeat".

3.16 Verify Volume Control Tank level is being maintained.

l 3.17 Secure any excess Condensate Booster Pumps and Hoewell Pumps.

3.18 Reset E1 Flux at Shutdown Alarm when neutron flux decreases below setpoint.

3.19 Notify Chemistry to obtain a NC System baron sample. Perform a reactivity balance calculation and maintain a shutdown margin equal to or greater than 1.6% Ak/k-par OP/0/A/6100/06 (Reactivity Balance Calculation).

3.20 Notify Plant Manager or Superintendent of Operations per Station Directive 3.1.6 (Notifying Management of Operating Conditions).

3.21 P hee boilers in operation pa OP/1/3/6250/073 (Electric Boilers) as necessary.

3.21.1 As 115-120 (Auz. Elec. Elz. A & 3 to AS Isol.) is opened slowly, throttle closed 1AS-12 (Unit 1 SM to AS Edr. Cont. Inlet Isol.).

3.22 Take manual control and close the folicrring valvas:

1CF-32 (Steam Gen.1A FDW Con =ol) 1CF-23 (Staam Gen. 13 FDW Control) 1CF-20 (Steam Gen.1C FDW Control) 1CF-17 (Stamm Gen. 1D FDW Con nol) 1CF-104 (Steam Gen. la FDW Control Bypass Control)13-105 (Stasa Gen.13 FDW Control Bypass Control) 1CF-106 (Steam Gen.1C FDW Control Bypass Control) 1CF-107 (Stasa Gen. 1D FDW Control Bypass Control) 3.23 Rasat Train A & 3 C Isolatior..

. 3.24 Position the fallowing valvaa:

S/G "A": Close 1CF-150 (G Tampa ing now to S/G 1A,13,1C, and ID Au;t. Feedvata: Nozzla Isol.)

Open 1CF-126-3 (S/G 1A G to CA Noz la Isol.) j open 1CF-151-A (G Tamparing now to S/G 1A Auz. Feedwater Noz:la isc:..)

S/G "3": Open 1CF-127-3 (S/G 13 CF to CA Naz la Isol.)

Open 1CF-153-A (G Tampating now to S/G 13 Auz. Feedwata Isol.) l S/G "C": Open 1CF-128-3 (S/G 1C CF to CA Nostle Isol.)

Open 1CF-155-B (CF Tamparing now to S/G 1C Auz. Feedvatar Isol.)

S/G "D": Open 1CF-129-B (S/G 1D G to CA Noz=la Isol.) j open 1CF-157-3 (G Tamparing now to S/G 1D Auz. Feedware: Isol.)

3.25 Start a Faadwater Pump par CP/1/A/6250/01 (Condensata and Faadwata: Systan) and secura A*"=7 Faadwater pa: OP/1/A/6250/02 (w"=7 Feedwater System) when desired and maintained stasa generator latvals at no load values ( 25%).

3.26 If an ATWS has occurred, refer to EP/0/A/5000/32 (Alert) and EP/0/A/5000/34 1 (General Emergency) and bring the plant to cold shutdown within 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. l l

3.27 Determine the cause of the reactor trip and correct the problem. If restart J

i is desired, rafar to OP/1/A/6100/05 (Rasctor Trip Recovery).

NOTE: If Raactor Trip occurred during startup and <152 power, restart 1

may commence per OP/1/A/6100/01 (Controlling Procedure for Unit Startup.

If shutdown is necessary, refer to OP/1/A/6100/02 (Controlling Procedure for Unit Shutdown). I 3.28 After tbs count rate has decreased to .5 decada below the " Source Range High Flux Laval at Shutdown" alarm setpoint and if borated tc,1.62 Ak/k xanon free value at 200*F, the shutdown banks may be inserted if desired.
