1. 0FP01PA(0FP01PB) - NFPA codes require dies el engine operation at rated speed for a minimum of 30 minutes. 2. Operating diesel engine for 60 minutes at rated speed prolongs engine life. 3. The following 4 starting methods ar e listed in order of preference, as needed the operator may us e any of the methods listed.
After starting an engine per 8.5.8.2, taking the 0FP01PA(B) Main Control Switch out of Test will result in fire pump shutdown unless a valid start signal is present.
Use of the Mantrol Switch bypasses all Diesel Fire Pump alarms, therefore an operator should be present to frequently monitor engine operating parameters. If the Mantrol Switch is used to start th e Diesel Fire Pump, it can only be stopped by placing the Mantrol switch to OFF.
This procedure is to be used only if the Fire Pu mp Controller is out of service and therefore, an operator must be present to frequently monitor engine operating parameters.

2015-301 Narrative Summary
Event # Description
- 1. Cross-tie 480V Buses 1L & 1M with 1L supplying Following shift turnover, t he SRO will direct the BOP Operator to c ro ss-tie 480V Buses 1L & 1M with 1L supplying per CPS 3 502.01 480 VAC Distribution section 8.1.4 Transferring a 480V Bus: Paralleling Method. 2. Raise power with rods to 29%
The crew will raise Reactor power with Control Rods to achieve ~29% Reactor Power IAW CPS 300 4.01 TURBINE STARTUP AND GENERATOR SYNCHRONIZATION in preparation for transferring RR pumps to FAST speed.
- 3. Uncoupled rod
When the first in
-sequence control rod reaches position 48, the ATC will perform a coupling check IAW CPS 3304.02 Rod Control And Information System (RC&IS) section 8.1.10 Coupling Check by applying a continuous withdraw to the rod at position 48. Annunciator 5006
-5G Rod Overtravel will be received, indicating that the control rod has become uncoupled from its drive mechanism. The operating crew will attempt to recouple the control rod IAW the annunciator response procedure. The SRO will evaluate and enter ITS 3.1.3 Condition C until the control rod is successfully recoupled.
- 4. TDRFP 'A' High Bearing Temperature Annunciator 5002
-2C HIGH TEMP RFPT 1A BRG comes in due to a failed bearing in the 'A' RFPT. With the 'B' TDRFP tagged out, the crew will start the MDRFP and secure the 'A' TDRFP IAW CPS 3103.01 Feedwater (FW) section 8.3.6 High Temperature TDRFP Bearings.
- 5. MC Pump 1B coupling failure Annunciator LOW PRESS MAKE
-UP COND XFER PUMPS DISCH HDR (5014
-2C) comes in due to the Make-Up Condensate Transfer Pump 1B (0MC01PB) shaft shear.
The BOP Operator will dispatch an Equipment operator to investigate. Upon the report of a shaft shear, the BOP operator will stop the failed pump and start the standby pump per CPS 3208.01 Cycled/Makeup Condensate Section 8.1.1 (or 8.2.2).
- 6. Loss of Control Power to Suppression Pool Dump Valve (1SM001A) Annunciator NOT AVAILABLE SM SYSTEM DIVISION 1 (5041
-7D) comes in due to a blown control power fuse deenergizing relay 74
-SM1A (1SM001A Bkr Overload relay). The BOP operator will dispatch a Equipment operator to investigate. Technical Specification LCO 3.6.2.4, Action C.1 will be evaluated requiring the restoration of the SPMU subsystem to operable status within 7 days.
- 7. Low Flow CW Bearing Seal Water Annunciator 5041
-3G LOW FLOW CW PUMP 1C BRG SEAL WATER comes in due to CW Pump 'C' seal water flow less than the setpoint (15 gpm). The BOP operator will dispatch an Equipment Operator to investigate. Seal water flow to Circulating Water (CW) Pump 1C cannot be restored requiring the BOP operator to trip CW Pump 1C and start CW Pump 1A. 8. RPV Instrument Line leak An RPV instrument line will break resulting in a partial loss of RPV instrumentation, a steam leak in the secondary containment and EOP
-8 entry. Two areas in secondary containment will exceed Maximum Safe temperature requiring blowdown. The crew may Anticipate Blowdown using bypass valves prior to two areas reaching max safe.
- 9. Radiation Monitor fails to isolate VF/Startup VG Due to the RPV instrument line leak in the secondary containment, the VF exhaust radiation monitor s trend up to the trip isolation set point but fail to actuate VF system isolation and start of VG requiring BOP to manually perform.
ILT 14-1 NRC Exam Scenario 1 Rev. 0 ILT 14-1 NRC Exam Scenario 1 CE Approved.doc Page 4 of 21 EOP 8, 1, 3 Critical tasks:
SC-1.1 ATC inserts a manual Scram before area temperature reaches max safe in any one area. SC-1.2 SRO enters EOP
-3 and performs a blowdown when 2 or more areas are above the max safe value of the same parameter (Table T, U, W), and a Primary System is discharging into the Secondary Containment, which cannot be isolated. If the crew Anticipates Blowdown using bypass valves, and in doing so two areas do not reach a max safe condition, then this critical task is considered to be met.
(PRA) Crew takes manual action to start at least one Standby Gas (VG) train and isolate VF when high rad initiation signals are received but automatic actions fail to occur.

After starting an engine per 8.5.8.2, taking the 0FP01PA(B) Main Control Switch out of Test will result in fire pump shutdown unless a valid start signal is present.
Use of the Mantrol Switch bypasses all Diesel Fire Pump alarms, therefore an operator should be present to frequently monitor engine operating parameters. If the Mantrol Switch is used to start th e Diesel Fire Pump, it can only be stopped by placing the Mantrol switch to OFF.
This procedure is to be used only if the Fire Pu mp Controller is out of service and therefore, an operator must be present to frequently monitor engine operating parameters.

2015-301 Narrative Summary
Event # Description
- 1. Cross-tie 480V Buses 1L & 1M with 1L supplying Following shift turnover, t he SRO will direct the BOP Operator to c ro ss-tie 480V Buses 1L & 1M with 1L supplying per CPS 3 502.01 480 VAC Distribution section 8.1.4 Transferring a 480V Bus: Paralleling Method. 2. Raise power with rods to 29%
The crew will raise Reactor power with Control Rods to achieve ~29% Reactor Power IAW CPS 300 4.01 TURBINE STARTUP AND GENERATOR SYNCHRONIZATION in preparation for transferring RR pumps to FAST speed.
- 3. Uncoupled rod
When the first in
-sequence control rod reaches position 48, the ATC will perform a coupling check IAW CPS 3304.02 Rod Control And Information System (RC&IS) section 8.1.10 Coupling Check by applying a continuous withdraw to the rod at position 48. Annunciator 5006
-5G Rod Overtravel will be received, indicating that the control rod has become uncoupled from its drive mechanism. The operating crew will attempt to recouple the control rod IAW the annunciator response procedure. The SRO will evaluate and enter ITS 3.1.3 Condition C until the control rod is successfully recoupled.
- 4. TDRFP 'A' High Bearing Temperature Annunciator 5002
-2C HIGH TEMP RFPT 1A BRG comes in due to a failed bearing in the 'A' RFPT. With the 'B' TDRFP tagged out, the crew will start the MDRFP and secure the 'A' TDRFP IAW CPS 3103.01 Feedwater (FW) section 8.3.6 High Temperature TDRFP Bearings.
- 5. MC Pump 1B coupling failure Annunciator LOW PRESS MAKE
-UP COND XFER PUMPS DISCH HDR (5014
-2C) comes in due to the Make-Up Condensate Transfer Pump 1B (0MC01PB) shaft shear.
The BOP Operator will dispatch an Equipment operator to investigate. Upon the report of a shaft shear, the BOP operator will stop the failed pump and start the standby pump per CPS 3208.01 Cycled/Makeup Condensate Section 8.1.1 (or 8.2.2).
- 6. Loss of Control Power to Suppression Pool Dump Valve (1SM001A) Annunciator NOT AVAILABLE SM SYSTEM DIVISION 1 (5041
-7D) comes in due to a blown control power fuse deenergizing relay 74
-SM1A (1SM001A Bkr Overload relay). The BOP operator will dispatch a Equipment operator to investigate. Technical Specification LCO 3.6.2.4, Action C.1 will be evaluated requiring the restoration of the SPMU subsystem to operable status within 7 days.
- 7. Low Flow CW Bearing Seal Water Annunciator 5041
-3G LOW FLOW CW PUMP 1C BRG SEAL WATER comes in due to CW Pump 'C' seal water flow less than the setpoint (15 gpm). The BOP operator will dispatch an Equipment Operator to investigate. Seal water flow to Circulating Water (CW) Pump 1C cannot be restored requiring the BOP operator to trip CW Pump 1C and start CW Pump 1A. 8. RPV Instrument Line leak An RPV instrument line will break resulting in a partial loss of RPV instrumentation, a steam leak in the secondary containment and EOP
-8 entry. Two areas in secondary containment will exceed Maximum Safe temperature requiring blowdown. The crew may Anticipate Blowdown using bypass valves prior to two areas reaching max safe.
- 9. Radiation Monitor fails to isolate VF/Startup VG Due to the RPV instrument line leak in the secondary containment, the VF exhaust radiation monitor s trend up to the trip isolation set point but fail to actuate VF system isolation and start of VG requiring BOP to manually perform.
ILT 14-1 NRC Exam Scenario 1 Rev. 0 ILT 14-1 NRC Exam Scenario 1 CE Approved.doc Page 4 of 21 EOP 8, 1, 3 Critical tasks:
SC-1.1 ATC inserts a manual Scram before area temperature reaches max safe in any one area. SC-1.2 SRO enters EOP
-3 and performs a blowdown when 2 or more areas are above the max safe value of the same parameter (Table T, U, W), and a Primary System is discharging into the Secondary Containment, which cannot be isolated. If the crew Anticipates Blowdown using bypass valves, and in doing so two areas do not reach a max safe condition, then this critical task is considered to be met.
(PRA) Crew takes manual action to start at least one Standby Gas (VG) train and isolate VF when high rad initiation signals are received but automatic actions fail to occur.
