Scenario Objective Evaluate the Team's ability to operate the plant with an electrical ATWS Scenario Summary  Initial Conditions:
: 1. Unit is at 5% power. 2. The following equipment is OOS:
: a. None 3. LCOs: a. None 
Scenario Sequence A control rod begins to drift out. The NSO must insert the rod to position 00 and it fails to latch when fully inserted. The Team will give it an individual scram signal and reference Tech Spec requirements.
The indicated flow to the CRD Flow Controller fails high. This causes the controller demand to the CRD FCV to fail low. If the team does not recognize the failure quickly and restore CRD cooling flow, the ROD DR I VE TEMP HI alarm comes up. The Team takes manual control of the CRD Flow Controller to restore system parameters to normal. A small, isolable break occurs on the 2B Core Spray pump piping, rendering the pump inoperable
. 2A Condensate/Booster Pump trips with failure of the STBY pump to auto start. Also
, the first pump the Team attempts to start will trip.
The other non
-running pump will start.
2 A RFP trips and when 2 B RFP auto starts, but after a short time, it also trips.
The 2C RFP can be started manually, but it also trips a short time later.
The Team will manually scram the reactor.
An electrical ATWS occurs when the reactor is scrammed. ARI is unsuccessful. The SBLC system fails to inject boron. The Team inserts control rods by pulling scram fuses, venting the scram air header, and / or driving control rods. Event One - Control Rod Drift Out A Control Rod will drift out Malfunctions required:
1  Control Rod K-08 drift out Success Path:
Control Rod fully inserted and individual scram signal applied.
The Control Room Supervisor references appropriate Tech Specs and makes correct LCO call.
ILT-N-3 Page 4 of 25 Rev. 00  (04/12)
Event Two
- Indicated Flow to CRD Flow Controller Fails High Indicated flow to the CRD Flow Controller fails high. This causes the controller demand to the CRD FCV to fail low. Malfunctions required:
1  Indicated flow to the CRD Flow Controller fails high Success Path:
The crew takes manual control of the CRD Flow Controller Event Three - Core Spray Leak / Localized Flooding A leak occurs on the 2B Core Spray pump casing.
Malfunctions Required:  1 2B CS pump casing weld failure.
Success Path:  Isolates the leak per DOA 0040

References Tech. Specs.
Event Four - Condensate/Booster Pump Trip with Failure of STBY to Auto Start 2A Condensate/Booster Pump trips with failure of the STBY pump to auto start. Also the first pump the Team attempts to start will trip.
Malfunctions required: 1 (Condensate/Booster pump trip with failure of STBY to auto start
) Success Path:  Starts a Condensate/Booster pump. Event Five
-  Loss of Feedwater All RFPs trip resulting in insufficient Feedwater flow.
Malfunctions required:
1    Loss of Feedwater
Success Path:
The Team performs a manual scram

Scenario Objective Evaluate the Team's ability to operate the plant with an electrical ATWS Scenario Summary Initial Conditions:

1. Unit is at 5% power. 2. The following equipment is OOS:
a. None 3. LCOs: a. None

Scenario Sequence A control rod begins to drift out. The NSO must insert the rod to position 00 and it fails to latch when fully inserted. The Team will give it an individual scram signal and reference Tech Spec requirements.

The indicated flow to the CRD Flow Controller fails high. This causes the controller demand to the CRD FCV to fail low. If the team does not recognize the failure quickly and restore CRD cooling flow, the ROD DR I VE TEMP HI alarm comes up. The Team takes manual control of the CRD Flow Controller to restore system parameters to normal. A small, isolable break occurs on the 2B Core Spray pump piping, rendering the pump inoperable

. 2A Condensate/Booster Pump trips with failure of the STBY pump to auto start. Also

, the first pump the Team attempts to start will trip.

The other non

-running pump will start.

2 A RFP trips and when 2 B RFP auto starts, but after a short time, it also trips.

The 2C RFP can be started manually, but it also trips a short time later.

The Team will manually scram the reactor.

An electrical ATWS occurs when the reactor is scrammed. ARI is unsuccessful. The SBLC system fails to inject boron. The Team inserts control rods by pulling scram fuses, venting the scram air header, and / or driving control rods. Event One - Control Rod Drift Out A Control Rod will drift out Malfunctions required:

1 Control Rod K-08 drift out Success Path:

Control Rod fully inserted and individual scram signal applied.

The Control Room Supervisor references appropriate Tech Specs and makes correct LCO call.

ILT-N-3 Page 4 of 25 Rev. 00 (04/12)

Event Two

- Indicated Flow to CRD Flow Controller Fails High Indicated flow to the CRD Flow Controller fails high. This causes the controller demand to the CRD FCV to fail low. Malfunctions required:

1 Indicated flow to the CRD Flow Controller fails high Success Path:

The crew takes manual control of the CRD Flow Controller Event Three - Core Spray Leak / Localized Flooding A leak occurs on the 2B Core Spray pump casing.

Malfunctions Required: 1 2B CS pump casing weld failure.

Success Path: Isolates the leak per DOA 0040

Event Four - Condensate/Booster Pump Trip with Failure of STBY to Auto Start 2A Condensate/Booster Pump trips with failure of the STBY pump to auto start. Also the first pump the Team attempts to start will trip.

Malfunctions required: 1 (Condensate/Booster pump trip with failure of STBY to auto start

) Success Path: Starts a Condensate/Booster pump. Event Five

- Loss of Feedwater All RFPs trip resulting in insufficient Feedwater flow.

Malfunctions required:
