- Ability to operate and monitor the following as they apply to a small break LOCA: RCS pressure and temperature DISTRACTOR ANALYSIS

a. This is the preferred method to lower PCS temperature and pressure per EOP

-4, LOCA procedure, however, candidate must recognize that due to loss of BUS 1A and 1B there are no Condensate Pumps in service, therefore, per EOP

-1.0, Operator actions we must close both MSIVs, resulting in the inability to use the TBV. PCPs are lost therefore we have no forced circulation and hence cannot use the PZR Main Spray Valves and must resort to utilizing the PZR Auxiliary Spray Valve to lower PCS pressure.

b. This is the preferred method to lower PCS temperature and pressure per EOP

-4, LOCA procedure; however, candidate must recognize that due to loss of Bus 1A and 1 B there are no Condensate Pumps in service, therefore, per EOP

-1.0 Operator actions, we must close both MSIVs, this results in the inability to use the TVB, second part is correct.

c. First part is correct, due to Busses 1A and 1B bein g de-energized, PCPs are lost and there is no forced circulation, therefore no PZR main spray. Therefore, must use PZR Aux Spray to lower PCS pressure

- Ability to determine or interpret the following as they apply to a Large Break LOCA: Significance of charging pump operation DISTRACTOR ANALYSIS

a. CORRECT b. First part is correct per EOP

-4.0 basis document (page 52 of 311, training emphasis section) states it is allowable to commence PCS cooldown as long as emergency boration is in progress. Loss of bus 1D results in loss of LC

-12, therefore, P

-55A and P-55B have no power. In addition, this also results in a loss of MCC

-2 and there is no boric acid pump feed available. Boric acid gravity feed is in service. P

-55C charging pump is in service providing 40 GPM charging line flow. For the second part the candidate may confuse this as being correct. This response actually comes from a requirement in EOP

-3 for SBO to verify the reactor will remain shutdown at 50 degree intervals.

c. Candidate incorrectly believes that additional chargin g pumps must be started to support emergency boration when in fact P

-55C is providing 40 GPM charging flow.

d. Candidate incorrectly believes that SDM must first be verified prior to commencing a cooldown.
