Turnover: Maintain 100% power Critical Tasks CT-18 Manually isolates feed water flow into and steam flow from the ruptured SIG before a transition to ECA-3.1 occurs.

CT-19 Manually establish/maintain an RCS temperature so that transition from E-3 does not occur because the RCS temperature is in either of the following conditions:

. Too high to maintain < 60 degrees CET sub cooling .

OR

. RED path on PTS Status Tree CT-20 Manually depressurize RCS to meet and maintain SI termination criteria while in E-3 prior to exceeding 100% SIG dome level on the simulator during a SGTR of 430 gpm or less (TH05 9.15%).

Appendix D Scenario Outline Form ES-D-1

SUMMARY

Event 1 -When directed by the lead examiner, SG Tube Leak develops on the #1 SG. The ATC will manually increase charging flow and subsequently isolate letdown using AOP-R.01 STEAM GENERATOR TUBE LEAK. The SRO will enter LCO 3.4.6.2.c Action a.

Event 2 - Blow down Isolation valve 15-44 fails to auto-isolate, the BOP will isolate Blow down flow by closing the SG Blow down Flow Control valve.

Event 3 - The crew will reduce power in response to the SGTL using AOP-C.03 RAPID SHUTDOWN OR LOAD REDUCTION.

Event 4 - When directed by the Lead Examiner, the# 3 Heater Drain Tank level control valve fails open resulting in a runback signal. The BOP initiates a Main Turbine runback using the valve position limiter using AOP-S.04 CONDENSATE OR HEATER DRAINS MALFUNCTION.

Event 5 - Following the manual runback, a malfunction causes the control rods continue to insert beyond the normal position; the ATC places control rods in manual using Immediate Operator Actions and AOP-C.01 ROD CONTROL SYSTEM MALFUNCTIONS to stop the excessive insertion. The SRO enters the Control Bank Rod Insertion Limit LCO. The ATC will initiate emergency boration to aid in compliance with the LCO.

Event 6 - The tube leak will degrade to a SGTR; the crew will trip the reactor, initiate Safety Injection and enter E-0, REACTOR TRIP OR SAFETY INJECTION. The crew will isolate and cool down the ruptured SG and depressurize the RCS using E-3, STEAM GENERATOR TUBE RUPTURE.

Event 7 - The #1 SG Atmospheric Dump fails open when the reactor trips. The BOP manually closes the Atmospheric Dump using prudent operator actions. (Credit sought for a post trip component malfunction for the BOP. The verifiable action is a Prudent Operator Action that only the BOP will perform.)

SUMMARY

Event 1 - The crew raises plant power using G0-5 section 5.1 from 95% to 100% power Event 2 - When directed by the lead examiner, 120 V vital power breaker to lower Containment radiation monitor 1-RM-90-106 trips. The SRO will enter LCO 3.3.3.1 action 27 and LCO 3.4.6.1 action b.

Event 3 - When directed by the lead examiner, the 3A Heater Drain Pump trips resulting in a Main Turbine run back. The A TC manually inserts control rods due to a failure of the Rod Control system using prudent operator actions.

Event 4 - When directed by the lead examiner, the pressurizer level channel LT 68-339 will fail low resulting in letdown isolation and de-energizing Pressurizer heaters. The ATC will remove the channel from service and restore Letdown using AOP-1.04, PRESSURIZER INSTRUMENT AND CONTROL MALFUNCTIONS. The SRO will enter LCO 3.3.1.1 Action 6 and LCO 3.3.3.7 Action 2.

Event 5 - When directed by the lead examiner a failure will occur on #1 SG Steam Flow Instrumentation. The BOP will place the Feed Regulating Valve to #1 SG in MANUAL and control SG level using AOP-S.01 MAIN FEEDWATER MALFUNCTIONS.

Event 6 -A leak will develop in the Condenser Cooling water system in the Turbine Building.

The crew will trip the Reactor. The BOP will stop all Unit 1 CCW pumps and isolate all Unit 1 Main Condenser Water boxes to stop the leak using AOP-M.08 INTERNAL FLOODING.

Event 7 - When directed by the lead examiner, a SBLOCA will develop. The crew will respond using E-0, REACTOR TRIP OR SAFETY INJECTION to initiate Safety Injection and ultimately transition to E-1 LOSS OF REACTOR OR SECONDARY COOLANT.

Event 8 - During the safety Injection, the A SI pump will trip and the B SI pump will fail to AUTO start, the ATC will manually start the B SI pump. (Credit sought for a post trip component malfunction for the ATC. The verifiable action is a Prudent Operator Action that only the ATC will perform.)

Allow at least 15 minutes between batches. [C.5] (C.7]

CAUTION2 Returning the Boric Acid Blender to service after unplugging, cleaning, or maintenance on the Boric Acid System could introduce debris, sludge, air or chunks of solidified boron into the CCP suction resulting in pump damage. Extreme care must be exercised to properly flush the Boric Acid Blender system following an outage. [C.2]

NOTE1 If an excessive amount of dilution is required (plant startup}, the pressurizer heaters should be energized to cause pressurizer spray operation for equalizing boron concentration in RCS and pressurizer.

NOTE2 Dilute mode will be used anytime a long-term positive reactivity addition is desired_ The operator should use the normal dilute mode whenever conditions permit Examiner Note: Dilutions will be performed based on the Reactor Engineering provided Reactivity Spreadsheet SRO [1] ENSURE unit is NOT in a Tech Spec or TRM action that prohibits positive reactivity additions.

SUMMARY

Event 1 - When directed by the Lead Examiner, Injection Water Pump A Trips with a failure of the B Injection Water pump to AUTO Start. The BOP manually starts the B Injection Water pump using the ARP.

Event 2 - When directed by the Lead Examiner, turbine first stage pressure transmitter, PT 73, will fail high. The ATC will place control rods to MANUAL to stop the continuous rod withdrawal using Immediate Operator Actions of AOP-C.01, Rod Control System Malfunctions.

The crew will transition to AOP-1.08, Turbine Impulse Pressure Instrument Malfunction to address the RCS temperature control, feed water control and steam dump realignment. The SRO will enter LCO 3.3.1.1 Action 8.b.

Event 3 - RCS Loop #2 Flow 1-FT-68-29B Transmitter Fails Low, the SRO enters LCO 3.3.1.1, Action 6.

Event 4 -An Exciter Insulation Resistance Low alarm is received. The crew will reduce power in response to the Main Generator alarm using AOP-C.03 RAPID SHUTDOWN OR LOAD REDUCTION.

Event 5 - Upon the initiation of the reduction in power, normal boration controller FIC-62-139 fails closed; the ATC initiates Emergency Boration using AOP-C.03 RAPID SHUTDOWN OR LOAD REDUCTION, APPENDIX I EMERGENCY BORATION to facilitate the reduction of power.

Event 6 - During the reduction in power, Feed Regulating valve FCV-3-48 fails to control in AUTO, the BOP places FIC-3-48 in MANUAL to control SG level on program using the Immediate Operator Actions of AOP-S.01 MAIN FEEDWATER MALFUNCTIONS.

Event 7 - The "A" Main Feed water pump trips, the crew manually trips, the Reactor and enters E-0, REACTOR TRIP OR SAFETY INJECTION.

Event 8 - The Main Turbine fails to AUTO trip; the BOP manually trips the Main Turbine during Immediate Operator Actions of E-0, REACTOR TRIP OR SAFETY INJECTION. (Credit sought for a post trip component malfunction for the BOP. The verifiable action is an Immediate Operator Action that only the BOP will perform.)

Event 9 - All Auxiliary Feed water pumps fail. The SRO transitions to FR-H.1 LOSS OF SECONDARY HEAT SINK and establishes Feed water using a Main Feed water pump. (Credit sought for a post trip component malfunction for the BOP. The verifiable action is an action that only the BOP will perform.)

Appendix D Required Operator Actions Form ES-D-2 Op-Test No.: 2015-301 Scenario No.: 5 Event No.:8 Event

Description:

AFW Failure/FR-H.1 Time Position Applicant's Actions or Behavior CAUTION If automatic SI signals are NOT blocked, feed flow should be carefully controlled to prevent rapid cooldown which could result in low steam line pressure SI actuation (and subsequent feedwater isolation).

NOTE 0.2 x 106 lbm/hr feed flow is equivalent to approximately 440 gpm.

Due to inaccuracy of flow indication at low end of scale, feed flow should be determined based on a rise in indicated flow.

ADJUST MFW regulating bypass valve controller to establish required feed flow.

The scenario may be terminated when the crew establishes at least 440 gpm feedwater flow or earlier, at the discretion of the Lead examiner.
