The skimmer surge tanks prevent draining an excessive amount of water from the fuel pool in case of a line break on the fuel pool cooling system suction lines. The lowest level the pool will drain to is 22.1' (normal is 22.4' to 22.7'). The purpose of the skimmer surge tank and the anti-siphon check valves often are confuse The skimmer surge tank on the suction from the pool and the anti-siphon check valves on the return to the pool. The difference is that the skimmer surge tank only allows the fuel pool to lower several inches and the antisiphon check valves prevent the pool from being drained completely since the return line goes all the way to the bottom of the pool. A. Incorrec Fuel pool level will not decrease below the top of the fuel and an Alert Emergency will not exist. Plausible because if the candidate confuses the purpose of the skimmer surge tanks with the anti-siphon check valves. Both are designed to limit the loss of water from the pool, but if a line break occurred with the check valves failing, the pool would be drained to a level below the top of the fuel that is seated in the fuel pool. An Alert would exist iflevel decreased to the top of the fuel. B. Incorrec Fuel pool level will not decrease below the top ofthe fuel and a NUB will not exist. Plausible because if the candidate confuses the purpose of the skimmer surge tanks with the anti-siphon check valves. Both are designed to limit the loss of water from the pool, but if a line break occurred with the check valves failing, the pool would be drained to a level below the top of the fuel that is seated in the fuel pool. An NUE would exist as a result of decreasing level, and then be upgraded to an Alert when level reached the top of fuel. C. Correct. Level will not decrease below the top of the fuel, but a low suction pressure trip will occur and the Fuel Pool Cooling system will be lost. Decay heat removal will be required using the D HR system. D. Incorrec The RHR fuel pool cooling assist mode can not be placed in service with the current plant condition RHR must be in Shutdown Cooling to place fuel pool cooling assist mode. Plausible because the first part is correct and for a different set of plant conditions, the RHR fuel pool cooling assist mode is a common method for removing decay heat from the fuel pool.

Thursday, January 15, 2009 10:29:21 AM 168 HL T 4 NRC Exam Description; EOPs require a minimum Of 5 SRVs to Emergency Depressurize the RPV. Prior to core loading for a "two year operating cycle", the Minimum Number of SRVs Required for Emergency Depressurization was 4. The increase in the amount of fuel loaded into the core necessitated the change to 5 SRVs. The Minimum Number of SRV s Required for Emergency Depressurization is defined to be the greater of either: 1. The least number of SRV s which, if opened, will remove all decay heat from the core at a pressure sufficiently low that the ECCS with the lowest head will be capable of making up the SRV steam flow, OR 2. The least number ofSRVs which correspond to a Minimum Alternate RPV Flooding Pressure sufficiently low that the ECCS with the lowest head will be capable of making up the SRV steam flow at the corresponding Minimum Alternate RPV Flooding Pressur A. Incorrec see description above. 1 st part is correct, 2nd part is not correct. Plausible

-The basis for 5 SRVs is that they will provide the steam flow necessary to maintain clad temperature below 1 ,500F. Self sustaining Zirc-Water reaction occurs at 2,200F. B. Incorrec see description above. 1st part is not correct (requires 5 SRVs). 2nd part is not correct Plausible

The candidate is expected to analyze plant conditions to come up with this determinatio The candidate is told that flashing is directly observed on the GEMACs and one of the Fuel Zone Instrument The candidate must know the reference legs for the 2C32-R606A-C RWL indicators are the same as for the Fuel Zone indicators, therefore the Fuel Zone instruments are not usable. When all RWL indication is lost, with a Cold Shutdown Rod Configuration, the EOPs direct emergency depressurization of the RPV and injection with all available sources at rated flow. EOPs caution 2 states that the wide range instruments are not to be used following a rapid depress (> 1 00 degrees/hour)

Suppression Chamber ONLY as necessary to maintain containment pressure below 56 psig Thursday, January 15,2009 10:30:04 AM 210 HL T 4 NRC Exam Description:

When emergency venting the containment you would normally want to vent from the torus, but in this case torus level is too high. The EOPs do not allow venting the torus if torus level is above 300", the upper limit of the instrumentatio Also normally when venting is performed, pressure is decreased until it is slightly above 0 psig, but in this case venting is only performed as necessary to protect the containment (maintained below 56 psig but not lowered significantly), but at the same time limiting the radiation release to the public. A. Incorrec Drywell pressure should only be decreased to a point to prevent containment failure, while limiting the release to the public lAW 31EO-EOP-I01- Plausible because this is the pressure that the Drywell is normally vented to per the EOP PC flowchart (non-Emergency Venting).

B. Incorrec Torus level is too high to vent the suppression (>300"). Plausible because per the EOP PC flowchart the suppression chamber is the preferred vent path.
