Unit 2 is at 100% power. 1A CA Pump has been removed from service for PMs. 1A CA Pump has been inoperable for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and is expected to be returned to service in 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. Direction for the crew is to shift operating NV (Centrifugal Charging) Pumps by starting 1B NV Pump and securing 1A NV Pump. 1B NV Pump pre
-start check has been successfully completed.
Event 1 Shift NV Pumps by starting 1 B NV pump and securing 1 A NV Pump. Event 2 Atmospheric dump valve 1SV
-40 fails open. Crew must take action to isolate this steam leak. This can be accomplished using AP/28 (Steam Leak), or crew can decide to use OMP 1-7 guidance to isolate a known leak. Verifiable Action
- RO will close associated isolation valve (1SV
-50). Event 3 1B CFPT suction valve will fail closed. The automatic CFPT trip (low flow) will not occur, requiring manual action to trip. Following the CFPT trip, the annunciator for Rod Insertion Lo/Lo limit will illuminate requiring TS evaluation.
Verifiable Action
- BOP will manually trip 1B CFPT.
Event 4 Following the CFPT 1B trip, a turbine runback will occur and AP/03 (Load Rejection) will be entered. Due to the runback rods should auto insert, but this feature will be failed, requiring the RO to manually insert rods. Verifiable Action
- RO will manually insert control rods as necessary to maintain Tavg/Tref within 1°F.
Event 5 KC miniflow valve 1KC
-C37A will fail open. Crew will enter AP/21 (Loss of Component Cooling) to address the miniflow valve issue. Attempts to manually close 1KC
-C37A will not be successful. TS 3.7.7 Action A will be entered for 'A' train KC being inoperable
. Verifiable Action
- BOP will start additional KC pump in order to provide adequate flow to in service loads. Event 6 1A CFPT will spuriously trip. AP/06 immediate actions require the RO to trip Unit 1 reactor on loss of all CF flow to any S/G
. The reactor will fail to trip from the control room requiring entry into FR
-S.1. Once emergency boration flowpath is aligned (1NV
-236B open), the reactor will trip.
Verifiable Action
- RO will manually insert control rods and BOP will initiate emergency boration.
Catawba Nuclear Station NRC Exam May 2016 Appendix D Scenario Outline Form ES-D-1 Appendix D Catawba NRC Exam May 2016 Scenario 2 NUREG 1021 Revision 10 Page 4 of 63 Scenario 2
- Summary Event 7 1B CA pump will fail to start (and cannot be manually started) following the reactor trip.
Verifiable Action
- RO will manually start the #1 CAPT.
Event 8 Twelve minutes following initiation of emergency boration the CAPT will experience an overspeed trip. With S/G N/R levels < 11% and no CA flow possible, a transition to FR
-H.1 (Response to Loss of Secondary Heat Sink) will be required. Following transition to FR
-H.1, steam generator depressurization will be required to establish feed flow from the CM system.
Verifiable Action
- Align feed flow to establish increasing S/G levels.
Event 9 During performance of FR-H.1, an attempt to depressurize the RCS using Aux Pressurizer Spray will not be effective due to failure of 1NV
-37A (NV Supply to Pzr Aux Spray) to open. RCS depressurization using a Pressurizer PORV will be required.
Verifiable Action
- BOP will depressurize RCS using a Pzr PORV. Critical Task 1
- Insert negative reactivity into the core by at least one of the following methods before completing the immediate action steps of FR
-S.1: De-energize the control rod drive MG sets Insert RCCAs Establish emergency boration flow to the RCS Critical Task 2 - Establish required feedwater (450 gpm) flow into at least one S/G before RCS bleed and feed is required.

BOP 3.1 IF shifting from 1 A NV Pump in service to 1 B NV Pump in service, perform the following:
CAUTION: If an NV Pump has been idle for an extended period of time, a boron transient may be initiated when it is placed in service. The volume of 1 A NV Pump and associated piping is 103 gallons; the magnitude of the transient will be minimal.
Shifting charging pumps at low NC System pressures (< 1000 psig) with NC Pump(s) in service will result in hydraulic transients being placed on the NC Pump seal packages. Operating experience shows that these transients will affect seal return flow. (PIP 09
-2596) NOTE TO EVALUATOR:
Step 3.1.1 and the preceding note will not be applicable.
NOTE: A loss of 1EPD with only the 1B NV Pump running will isolate normal letdown due to an indicated loss of both charging pumps; the loss of 1EPD will also disable the LTOP function of 1NC
-32B (PZR PORV) creating a challenge to LTOP. This challenge does NOT occur if either the 1A NV Pump is in service or ND Letdown is in service. (PIP C 1241) BOP 3.1.1 IF Unit 1 is in Mode 4 with any RCS cold leg
< 210°F, or Mode 5, or Mode 6 when the reactor vessel head on, make log entry for 1NC

Unit 1 was performing a rapid downpower as a result of high Reactor Coolant activity when 1B S/G experienced a tube rupture. Current conditions are as follows:
The unit 1 Reactor was manually tripped from the Control Room 5 minutes ago.
Safety Injection was manually initiated and both trains are in service.
Following the Reactor trip, 1SV-13 (S/G 1B PORV) failed open. 1SV-28A (1B S/G PORV Isol) failed to close.
The most recent Chemistry sample results indicate Unit 1 DEI of 322 µCi/cc
. NCS Subcooling indicates (-)16°F and stable
. 1EMF-53A indicates 386 R/hr.
1EMF-53B indicates 392 R/hr.
Upper wind direction (C1P0250) indicates 493.5 degrees A General Emergency has been declared per RP/0/A/5000/001 (Classification of Emergency)

STANDARD: Candidate refers to the initiating cue and RP/01 to determine that the 1B S/G Tube Rupture combined with the failure of 1B S/G PORV and associated isolation valve results in "Release of secondary side to environment with primary to secondary leakage GREATER THAN Tec h Spec allowable" which constitutes a Loss of Containment Barrier. The applicant continues to Step 2 of the RPSA criteria.
This step is critical to ensure that the candidate correctly determines PARs. If the candidate does not recognize a loss of Containment has occurred, assuming the GE was declared based on a loss of RCS and Fuel Clad barrier combined with a potential loss of Containment, the incorrect determination will be made.
