Unit 2 is at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump are tagged out for preventative maintenance.

Turnover: Unit 1 is just below POAH, MOL. Unit 2 is at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump are tagged out for preventative maintenance. The crew is to shift operating KC (Component Cooling) pumps by starting the 1B2 KC pump and securing the 1B1 KC pump and then increase power to1% by withdrawing control rods. LCO 3.0.4.(b) has been assessed for the 1B NI Pump inoperability and Mode change has been authorized.

Catawba Nuclear Station NRC Exam May 2014 Scenario 1 - Summary Initial Condition Unit 1 is just below POAH, MOL. Unit 2 is at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump are tagged out for preventative maintenance.

Turnover:

Unit 1 just below POAH, MOL. Unit 2 at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump tagged out. The crew is to shift operating KC (Component Cooling) pumps by starting the 1B2 KC pump and securing the 1B1 KC pump and then increase power to 1% by withdrawing control rods. LCO 3.0.4.(b) has been assessed for the 1B NI Pump inoperability and Mode change has been authorized.

Event 1 Shift operating Component Cooling pumps per OP/1/A/6400/005 (Component Cooling System), .17 (Shifting KC Pumps).

Event 2 Raise reactor power to 1%. Crew will use rods since unit is below POAH.

Event 3 1D S/G W/R level signal fails LOW; associated Feed Reg. Bypass Valve opens. RO takes manual control to stabilize and restore 1D S/G level. AP/06 (Loss of SG Feedwater) Case III entry. This failure is internal to the DCS and does not indicate on the W/R level board indication.

Event 4 AP/20 (Loss of Nuclear Service Water) entry. TS evaluation will indicate no LCO entry required.

Event 5 1B Main Feedwater Pump trips, along with the failure of the 1B AFW pump to auto start. AP/06 Case I entry. A TS evaluation required due to failure of the 1B AFW pump to start.

Event 6 1A NV Pump (Charging) trips. BOP manually starts the 1B NV pump to restore charging and letdown. AP/12 (Loss of Charging or Letdown) will be entered. TS evaluation required.

Event 7 1NC-36B (PZR PORV) fails open. RO attempts manual closure of the PORV. This will not be successful. AP/11 (Pressurizer Pressure Anomalies) entry. This is the major event because the PZR PORV cannot be closed, nor will the manual block isolation close. Recognizing a LOCA, the crew will determine that the reactor must be tripped.

Event 8 1A NI (Safety Injection) Pump fails to auto start on the SI signal. BOP manually starts to establish intermediate head injection flow.

Event 9 1CA-152 (S/G 1D CF BYP TO CA NOZZLE) fails to close on the feedwater isolation. RO manually closes the valve.

Critical Task 1 - Establish flow from at least one intermediate head ECCS pump prior to transition from E-0.

Appendix D Catawba NRC Exam May 2014 Scenario 1 NUREG 1021 Revision 9 Page 3 of 42

Catawba Nuclear Station NRC Exam May 2014 Critical Task 2 - Trip NC pumps on loss of subcooling with S/I flow verified per E-0 within 5 minutes of criteria met.

Critical Task 3 and 4 - Control S/G level to avoid RPS actuation.

Description:

Increase reactor power to 1%

Time Position Applicants Actions or Behavior EVENT 2 RO Withdraw control rods to increase reactor power.

NOTE TO EVALUATOR: The following actions are from OP/1/A/6100/001 (Controlling Procedure for Unit Startup), Enclosure 4.1 (Unit Startup).

NOTE: 1. Control rod withdrawal shall NOT exceed the temporary rod withdrawal limits specified in Unit One R.O.D. Section 2.3.

2. Refer to Unit One R.O.D. Section 2.4 for the rate at which reactor power can be changed.

3.The throttling of a S/G bypass reg valve affects the other S/G bypass reg valves. Therefore, SM/CF P needs to be monitored as the unit approaches POAH.

4.If NC boron concentration is greater than 1000 ppmB, T-AVG control may be very sensitive above the POAH due to a positive MTC. Unit One R.O.D. Section 5.10 provides MTC at the current conditions.

6. Per SOER 07-01 (Reactivity Management) it is recommended that Plant Operators monitor multiple indications such as Thermal Power Best Estimate, Nuclear Instrumentation, Steam Pressure. T's, CF Flowrate, and Turbine Load when making at power reactivity changes. (R.M.)
