Dresden Generating Station NRC ILT EXAM Scenario ILT-R-1 Scenario Objective Evaluate the operators in using the Failure to Scram contingency procedure.

Scenario Summary Initial Conditions:

• 15% power, unit startup in progress

• IRM 15 OOS

• 2B EHC Pump OOS

• Unit 3 is in Mode 1 Events:

• Transfer Aux Power from TR-22 to TR-21

• Raise reactor power by withdrawing control rods

• RPIS failure for rod F5

• Failure of the main generator voltage regulator in automatic

• Trip of the 2B recirc pump

• Trip of the 2A circ water pump with a failure of the 2B circ water pump to start

• Failure of RPS to deenergize and ARI to initiate

• Loss of main condenser vacuum Scenario Sequence

• The team transfers Aux Power from TR-22 to TR-21.

• The NSO, as directed by the SRO, then continues the power ascension for unit startup by control rod withdrawal.

• During the control rod withdrawal, a failure to a rod occurs and that rod must be driven in fully.

• The main Generator Voltage Regulator trips to manual while reducing Generator Voltage. The voltage reduction is continued in the Manual Mode.

• An electrical fault causes the 2B recirc MG set to trip. The team will carry out actions for a recirc pump trip, and enter single loop operation.

• 2A Circulating Water Pump trips on overload. The 2B Circulating Water Pump will fail to start due to an internal short.

• A Spurious Channel A scram occurs. An ATWS condition exists due to a failure of RPS A to deenergize and ARI is unsuccessful. The team should perform the ATWS DEOP. Pulling RPS fuses, venting the scram air header and driving control rods are successful. The event is complicated by a loss of RFPs and the team should control RPV level using the HPCI and / or CRD system.

• Due to 2A Circulating Water Pump tripping and the failure of 2B Circulating Water Pump to start, the Team experiences a loss of Main Condenser vacuum.

• The scenario is terminated when all rods are inserted and the plant stabilized.

14) Adjust VARS to 200 out

b. Run the initial setup caep file: ilt-r-1.cae

c. Verify the following simulator conditions:

1) Vars set at ~100

2) MWe at ~130.

ILT 01-1 NRC RE-EXAM, Scenario ILT-R-1 Page 19 of 26 Rev. 01 (11/02)

3) Condensate Demin DP between 20 and 45 psid.

4) Condensate pump amps between 160 and 255 amps

d. Secure the following equipment and tag out of service:

1) Place IRM 15 902-5 panel joystick in bypass and place an Equipment Status Tag on it.

2) Place 2B EHC Pump control switch in PTL and hang an OOS card on it

e. Advance the chart recorders.

f. Mark up rod sequence for current rod positions.

g. Complete the Simulator Setup Checklist.
