2011 NRC ILT Scenario #3 SCENARIO

SUMMARY

The scenario begins with reactor power at 90%. RCIC was operating in CST-CST for baseline vibration testing. An Engineer accidently bumped the Mechanical Trip arm and RCIC tripped. A visual inspection determined no damage to RCIC and the trip is ready to be reset and placed in standby IAW OI-150, Section 3.3.

Once RCIC is placed in standby, the crew will continue the Power adjustment. Then the B Recirc Pump flow controller will fail upscale and the operators will lock up the scoop tube IAW the AOP. The SRO will address Technical Specifications (TS) for the speed mismatch.

An EPA breaker will trip on A RPS resulting in 1/2 scram. The crew will enter the AOP, transfer RPS to the alternate supply and the 1/2 scram will be reset. The SRO will address TS for the EPA trip.

A leak will develop on the HPCI steam line in Secondary Containment and will not be isolable.

Area temperatures will rise requiring EOP entry and a reactor scram (CRITICAL TASK 1.0).

Additionally, as RPV level lowers RCIC will fail to initiate at its auto setpoint and must be placed in service manually for RPV level control. As area temperatures continue to rise, an Emergency Depressurization(ED) must be performed when the max safe operating limit is exceeded in more than one area (CRITICAL TASK 2.0). During the ED, one ADS SRV will fail to open and another SRV must be opened.

The scenario ends with the ED completed and RPV level at >170 inches.

RCIC was operating in CST-CST for baseline vibration testing. An Engineer accidently bumped the linkage for the Mechanical Overspeed Trip and RCIC tripped 40 minutes ago. A visual inspection determined no damage to RCIC and the trip is ready to be reset and placed in standby IAW OI-150, Section 3.3. The 2nd Assistant and the System Engineer are standing by in the RCIC room to observe the reset.

Torus Cooling and ESW were secured after RCIC tripped. A RCIC surveillance test will be run on the next shift.

A Load Line Adjustment is progress. When RCIC has been placed in Standby, continue the Load Line Adjustment. The directions are to pull step 34 rods to position 20 (symmetrical). Call the RE after all the step 34 rods are at position 20. He will provide further guidance then.

2011 NRC ILT Scenario #4 SCENARIO

SUMMARY

The scenario begins with the reactor at ~60% power and a shutdown in progress. The crew will perform the MSIV Trip/Close Functional Test. During the test, one MSIV will fail closed. The SRO will address Technical Specifications (TS) for the valve failure.

The crew will continue the shutdown by inserting control rods. While moving control rods, an APRM will fail upscale and the crew will take procedural actions to bypass the APRM and reset the 1/2 scram. Then, a RHR pump will spuriously start, with indications of pump overload on the motor ammeter. The pump will fail to trip. The SRO will address TS and direct removing the pump from service. Once TS are addressed, a loss of Non Essential 4160v Bus 1A1 will occur.

The crew will take actions IAW the AOP and address the resultant Recirc Pump trip and also swap bus power supplies. The SRO will address TS for single loop operation.

Then, the condensate pumps will trip causing a loss of Feedwater. The crew will insert a manual scram and the SRO will enter IPOI-5 due to the scram and EOP-1 due to low RPV level. After the initial scram actions are performed, a LOOP will occur with a small drywell leak.

The output breaker on the A SBDG will fail to close and cannot be closed. The B SBDG will fail to start and must be started manually to power an Essential Bus (CRITICAL TASK 1.0). As the operators attempt to recover RPV level, RCIC inverter will fail, which prevents RCIC from injecting and the HPCI flow controller will fail in AUTOMATIC, so it must be operated in manual to permit level recovery BEFORE an Emergency Depressurization is required (CRITICAL TASK 2.0).

The scenario may be terminated when the B essential bus is recovered and RPV level is

>170inches.
