Appendix D Scenario Outline Form ES-D-1 Facility: Sequoyah Scenario No.: 1 Op Test No.: 2013-301 Examiners: Operators:

Initial Conditions: Unit 1 is in MODE 1 76%, BOL Turnover: Unit 1 is in MODE 1 76%, BOL raise power to 100%.

D RCW pump is OOS for maintenance.

PT-3-1A is in Maintenance Bypass Target CTs: Manually trip the main turbine prior to the completion of E-0.

Isolate AFW flow into the ruptured (#1) SG by closing FCV-3-164 and 3-174 before a transition to ECA-3.1 occurs.

Establish cooldown and maintain RCS temperature so that transition from E3 does not occur because the RCS temperature causes an extreme (red-path) or a severe (orange-path) challenge to the subcriticality and/or the integrity CSF. (As required.)

Event No. Malf. No. Event Type* Event Description

1. RX05A I-ATC/SRO The controlling pressurizer level channel LT 68-339 will fail high TS-SRO resulting in charging flow decreasing and energizing Pressurizer backup heaters. The ATC will remove the channel from service and restore Pressurizer heaters using AOP-I.04. The SRO will address Tech Specs and determines the instrument is INOPERABLE.

2. CC01 C BOP/SRO A small leak develops on the Component Cooling Water system (CCS) with a failure of the CCS Surge Tank Makeup valve to AUTO open. The BOP manually opens the CCS Surge Tank Makeup valve.

3. TH05A C- ATC/SRO A small Steam Generator Tube Leak develops, the crew will TS-SRO respond using AOP-R.01. The ATC will raise Charging flow to maintain Pressurizer Level on program. The SRO will enter LCO 3.4.6.2.c, Action a.

4. R ATC The crew will reduce power using AOP-C.03, Rapid Power N SRO/BOP Reduction in response to the SGTL.

5. FW11A C-SRO/BOP At approximately 70% power, Main Feed Pump 1A develops an oil leak. The BOP trips the A MFWPT using ARP 1-AR-M3-B MAIN FEEDWATER PUMPS.

6. TH05A M-All The tube leak will degrade to a SGTR, the crew will trip the reactor enter E-0.

7. TC11ALL C-BOP The Main Turbine will fail to trip when the Reactor Trips, the BOP TC12ALL will manually trip the Main Turbine.

8. MS12A M-All When the reactor trips, the ruptured SG Atmospheric Dump will open, the crew will transition through E-2, E-3, and eventually to ECA-3.1.

2013-301 NRC Scenario 1 Summary EVENT 1 - When directed by the lead examiner, the controlling pressurizer level channel LT 68-339 will fail high resulting in charging flow decreasing and energizing Pressurizer backup heaters. The ATC will remove the channel from service and restore Pressurizer heaters using AOP-I.04. The SRO will address Tech Specs and determines the instrument is INOPERABLE and enters LCO 3.3.1.1 Action 6; and LCO 3.3.3.7 Action 2a.

EVENT 2 - When directed by the lead examiner, A small leak develops on the Component Cooling Water system (CCS) with a failure of the CCS Surge Tank Makeup valve to AUTO open. The BOP manually opens the CCS Surge Tank Makeup valve.

EVENT 3 - When directed by the lead examiner, a 15 gpm SG Tube Leak develops on the

1. 1 S/G. The ATC will manually increase charging flow and subsequently isolate letdown using AOP-R.01 STEAM GENERATOR TUBE LEAK. The SRO addresses Tech Specs and determines entry into LCO 3.4.6.2.c Action a is required.

EVENT 4 - The crew initiates a power reduction using AOP-C.03 RAPID SHUTDOWN OR LOAD REDUCTION due to the SGTL.

EVENT 5 - When directed by the lead examiner, at approximately 70% power, Main Feed Pump 1A develops an oil leak. The BOP trips the A MFWPT using ARP 1-AR-M3-B MAIN FEEDWATER PUMPS.

EVENT 6 - The tube leak will degrade to a SGTR, the crew will trip the reactor enter E-0 REACTOR TRIP OR SAFETY INJECTION.

EVENT 7 -. The Main Turbine will fail to trip when the Reactor Trips, the BOP will manually trip the Main Turbine.

EVENT 8 - When the reactor trips, the ruptured SG Atmospheric Dump will open, the crew will transition through E-2 FAULTED STEAM GENERATOR ISOLATION, E-3 STEAM GENERATOR TUBE RUPTURE, and eventually to ECA-3.1, SGTR AND LOCA -

SUBCOOLED RECOVERY.

The scenario may be terminated when the crew transitions to ECA-3.1.

EOP flow: E-0, E-2, E-3, ECA-3.1.

NR.

ATC ATC Examiner Note: MONITOR status trees, the crew will implement status tree monitoring via ICS. When a RED or ORANGE path status tree is observed, the SRO will designate one of the Board operators (typically the BOP) to verify status tree conditions using 1-FR-0, UNIT 1 STATUS TREES. Once verified, the SRO should direct the crew to transition to the appropriate RED and/or ORANGE path procedure(s).

When a RED Path for Containment is evident on ICS, the SRO will transition to FR-Z.1, go to page 41 for details.

SRO Transitions to E-2, Faulted Steam Generator Isolation.
