    Scenario 1 – Summary Initial Condition Unit 1 is at 75% power at the MOL. Unit 2 is at 100% power. Turnover: Unit 1 is at 75% power at the MOL. Unit 2 is at 100% power. 1A CA Pump has been removed from service for PMs. 1A CA Pump has been inoperable for 2 hours and is expected to be returned to service in 8 hours. Direction for the crew is to continue a power decrease to 13% (at 10% / hour) for turbine offline work. The Unit 1 RMWST is NOT aligned to supply Unit 2 per OP/2/A/6200/012 (Reactor Makeup Water). Event 1 Crew will use the provided reactivity plan to begin a power decrease to ~13%. BOP will perform a boration per the reactivity plan. RO will input a target and load rate into the turbine control panel and place the turbine in GO to commence power decrease. RO will also insert control rods as required to maintain RCS temperature. Event 2 1NC-36B (PZR PORV) fails open while BOP is responding to a rear board annunciator. Manual closure of the associated block valve will be successful. AP/11 (Pressurizer Pressure Anomalies) entry. TS evaluation required. Verifiable Action – RO will isolate PZR PORV by manually closing the associated PORV Isolation valve. Event 3 1B RN (Nuclear Service Water) strainer Hi D/P. AP/20 (Loss of Nuclear Service Water) entry. TS evaluation required. Verifiable Action – BOP will start an alternate RN Pump and secure 1B RN Pump. Event 4 1B NCDT (Reactor Coolant Drain Tank) Pump trips. Required actions contained in Annunciator Response Procedure. Verifiable Action – The BOP will start the 1A NCDT Pump per the ARP. Event 5 1CF-51 (S/G 1C CF CONT ISOL) valve fails closed. Both CFPTs will trip on Hi Discharge Pressure resulting in an AMSAC Turbine Trip. The Automatic Reactor Trip on Turbine Trip greater than 69% (P9) will fail. AP/06 (Loss of S/G Feedwater) Immediate Actions, and the failed Automatic Trip, will require the RO to manually trip the reactor. Verifiable Action – RO will manually trip the reactor. Event 6 Following unit trip, a rupture at the steam equalization header occurs. Verifiable Action – Crew will terminate Safety Injection following manual initiation of Main Steam Isolation. Event 7 Automatic Main Steam Isolation trains ‘A’ and ‘B’ fail to actuate on low S/G pressure. Manual initiation will be required. Verifiable Action – RO will manually initiate Main Steam Isolation on both trains.

    Scenario 1 – Summary Event 8 1A VE (Annulus Ventilation) Fan fails to start on Safety Injection signal. Manual start will be required. Verifiable Action – BOP will manually start the fan. Critical Task 1 – Manually isolate failed open Pressurizer PORV prior to reactor trip or ESF actuation. Critical Task 2 – Manually trip the reactor from the control room before 1C S/G dryout occurs (W/R S/G level < 12%). Critical Task 3 – Manually actuate Main Steam Isolation before a severe (orange path) challenge develops to either the subcriticality or the integrity CSF or before transition to ECA-2.1, whichever happens first.

    Scenario 2 – Summary Initial Condition Unit 1 is operating at 100% power at the EOL. Unit 2 is at 100% power. Turnover: Unit 1 is at 100% power at the EOL. Unit 2 is at 100% power. 1A CA Pump has been removed from service for PMs. 1A CA Pump has been inoperable for 2 hours and is expected to be returned to service in 8 hours. 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 1B NV pump and securing 1A 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.

    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.

    EVENT 1

    NOTE TO EVALUATOR: Crew begins by shifting the operating charging pump per OP/1/A/6200/001 (Chemical and Volume Control System), Enclosure 4.13 (Shifting Of the Operating Charging Pump). The initial conditions are complete.

    ALL

    NOTE: This enclosure affects reactivity and is designated important to Reactivity Management per AD-OP-ALL-0203 (Reactivity Management). (R.M.)

    BOP 3.1 IF shifting from 1A NV Pump in service to 1B 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 1A 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-12-1241)

    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-32B (PZR PORV) per the applicable:

    BOP 3.1.2 Ensure VCT pressure is between 18-40 psig as read on 1NVP5500 (VCT Vent Press) (1MC5).

    NOTE: If in an emergency situation, the 30 second delay after starting the Aux Oil Pump is NOT required before starting the NV pump.

    BOP 3.1.3 30 seconds prior to starting 1B NV pump, place "NV PUMP 1B AUX OIL PUMP" in the "ON" position.

    NOTE TO EVALUATOR: The crew will make a plant page to notify personnel of the start of the 1B Charging Pump

    BOP 3.1.4 Start "NV PUMP 1B". (R.M.)

    BOP 3.1.5 Place "NV PUMP 1B AUX OIL PUMP" in "AUTO".

    BOP 3.1.6 Stop "NV PUMP 1A".
