Commitment Document:

r ii Shift Turnover ATTACHMENT 1 A reactor startup is in progress. The plant is at approximately 8% CTP. The Reactor Mode Switch is in RUN. OP-65 is complete through Step D.22.3. ST-5D has just been completed and is satisfactory.

Chemistry has reported that all chemistry parameters are well within specification for Power Operation. I-131 Dose Equivalent is <.2uci/gm. EPIC is indicating thermal limit alarms that are evaluated by Reactor Engineering to be expected values. IT is looking into the EPIC issue. Reactor Engineer guidance is to continue reactor startuD with rods until 25%CTP. You are currently in RWM Step 26.

Commitment Document:

The crew will take the shift with the plant operating normally at -95% CTP following a rod pattern exchange. Following Reactor Analyst guidance, the crew will continue a power ascent to 100% CTP using recirculation flow. Shortly into the power ascent, the operators will notice that the non-controlling FWLC level instruments are trending down while the controlling is steady. The crew will diagnose that the FWLC controlling instrument has failed as is causing actual level to trend down slowly. The crew will take manual control, of FWLC, enter AOP-42 and determine the cause to be a failed instrument. The crew will then swap FWLC to the alternate instrument input and return to automatic level control. The Control Room Supervisor will consult technical specifications for the failed instrument. The Main Turbine will then lose part of a low pressure blade that will penetrate the low pressure turbine exhaust boot. This will be indicated by a step change in turbine vibration followed by a slow loss of condenser vacuum that will eventually worsen. Turbine vibration will result in entry to AOP-66 but will not be severe enough to require a turbine trip. The condenser vacuum loss will eventually result in AOP-31 entry which will require a power reduction. The vacuum loss will worsen such that power reductions with both recirculation flow and rods will occur. Eventually the AOP-31 manual scram milestone will be met. The manual scram will not be completely successful due to hydraulic blockage in one of the scram discharge volumes. Power will be above 2.5% requiring significant EOP-3 action. As a nuisance, one SDlV vent valve will fail to close. The EP-3 success path will be inserting rods with RMCS and repeated manual scrams. As vacuum continues to trend away, level control will need to transition to HPCl and pressure control augmented with SRVs.

The resultina challenge to containment may result in SLC injection if not already started.

NOTE:

The main turbine blade loss and resulting vibration are similar to an event that occurred at Cooper in May 2003. Reference OE-16340 Shift Turnover ATTACHMENT 1 The plant is operating normally at -95% CTP. A rod pattern exchange has just been completed and the reactor analvst quidance is to return to 100% CTP usina recirculation flow.

Commitment Document:

The scenario begins with the plant operating normally at 100% CTP. A repair of the C SW strainer has just been completed and the tags are clear. The shift will swap to the C SW pump in service and B in Standby to facilitate a pressure leak test of the C SW pump strainer. An LPRM will fail upscale resulting in a single APRM upscale trip. A half scram on APRM upscale will result. The crew will determine a failed LPRM as the cause and bypass the LPRM. The bypass will result in an INOP APRM on the 2 per levet count basis.

A Tech Spec review will identify a Potential LCO with trip function maintained by the remaining divisional APRMs. A fire in the SJAE After Condenser will require entry to AOP-5. Actions to extinguish the fire will not be successful until Rx power has been reduced with both recirculation flow and control rods. After the fire is out, a steam leak in the drywell will force entry into EOP-2 and 4. On the Manual Scram, a single rod will fail to insert and will subsequently be driven in by normal RMCS. On the fast transfer, the 10500 bus will experience catastrophic failure resulting in a loss of containment cooling capability with the A RHR loop as well as a loss of both A and B RHR pumps. This reduces EOP-4 actions to a single (D) RHR pump in the B loop. A sinnle d w e l l sprav evolution will result in scenario termination.
