| C. will remain validduetosufficient natural circulation.
| |
| D. isNOTassured toremain validunder these conditions.
| |
| | |
| Proposed Answer: D Explanation: ForReactor coolant temperature indications toremain valid, flow sufficient throughthe Reactor mustbemaintained toprevent thermal stratification. Therearethree recognizedmethods toassure valid Reactorcoolant temperature indications: flow maintain with anRWRpump, maintain flow with anRHRpumpintheSDClineup, and/or maintainReactor water level greater than 234.5inches toprovide adequate natural circulation. of10300 Theloss busresults inlossof RWR pumpA.Theloss of10500 busresults inloss ofRPSA,which also causes a loss ofSDC. Since Reactor water level isbelow 234.5 inches, flow insufficient through the core exists to prevent thermalstratification andinvalid Reactor coolant temperature indications.
| |
| Note: Thequestion meets theK/A by giving a loss ofloss ofShutdown Cooling(duetoloss of 10500 bus) and requiring the candidate tobe able to monitor theRHR/shutdown cooling response (isolation ofSDCduetoRPS A loss) andresulting temperature indication impact.
| |
| A. Incorrect -
| |
| SDCflow islost duetolossof 10500 bus, which causes loss ofRPSA andloss ofSDC.Plausible because RHRloop B still has apumpwith power available.

| |
| Adequate corecooling can beassured Condensate pumpB injects from the Hotwell, which isexternal tothe primary containment.
| |
| With HPCIaligned tothe CSTsandunable toberealignedtothe Torus, italso injects froma source external tothe primary containment. Core Spray pumpA injects from the T orus,which isnotexternal tothe primary containment.Therefore, the preferred injectionsource, withPCPL being challenged, isCore Spray pumpA.
| |
| A. Incorrect -
| |
| Core Spray isthe preferred injectionsource. Plausible because HPCIwould be apreferred injection source ific tould berealignedto take suction from the Torus. Also plausible because HPCIcaninject athigher Reactorpressures, hasfiner control, andis from arelatively cleaner source. Alsoplausible because Core Spray is specifically not preferred insomesituations (ATWS).
| |
| C. Incorrect -
| |
| Core Spray isthepreferred injectionsource. Plausible because Condensateis already injecting, hasfiner control, andis from arelatively cleaner source. Also plausible because Core Spray isspecifically not preferred insomesituations(ATWS).
| |
| D. Incorrect -
| |
| Core Spray isthe preferred injectionsource. Plausible because HPCIwould be a preferred injection source ific tould berealigned totake suction from the Torus.

| |
| A. EOP-5 entry isrequired tolimitradioactivity release toand from theReactor Building.
| |
| B. EOP-5 entry isNOTrequired because the Reactor coolant system isina lowenergy state.
| |
| C. EOP-5entry isNOTrequired because thecause oftheentry condition is known andit is NOTa primary system discharging into the Reactor Building.
| |
| D. EOP-5 entry isNOTrequired because the bases doNOTaddress a droppedfuel bundle andassume such anaccident ishandled using AOP-44, Dropped Fuel Assembly.
| |
| | |
| Proposed Answer: B Explanation: Thegiven area radiation monitor condition meets anEOP-5 entrycondition.
| |
| However, EOP basesspecifically doNOTrequire theEOPstobeentered ifReactorcoolant temperature islessthan 2120F anda Reactor startup orshutdown isNOTinprogress. Since theplant isin Mode 5,Reactorcoolant temperature isless than 2120F,anda Reactor or startup shutdown isNOT inprogress. Therefore EOP-5entry isNOTrequired.
| |
| Note: While the question deals with EOPentry, it rises tothe SROlevel because itisnot straight memory ofEOP entry condition, but also knowledge ofbases behind EOPentry requirements ("knowledge of administrative procedures that specify hierarchy,implementation, and/or coordination ofplantnormal, abnormal, andemergency procedures").
| |
| A. Incorrect -
| |
| Since theplant isin Mode 5,Reactor coolant temperature isless than212oF and a Reactor startup orshutdown is NOT inprogress. Therefore EOP-5entry isNOTrequired.
| |
| C.Incorrect -
| |
| EOP-5 bases statethatthe purpose of thehigh area radiation levelentry condition istodetect anddeal with a leak from a primary system dischargingintothe Reactor Building. However, there isnoguidance to NOTenter theEOP this if cause canbe ruled out.
| |
| D. Incorrect -
| |
| EOP-5 bases doNOTspecificallycover a dropped fuel bundle, howeverthereis noguidance toNOTenter theEOPduetoadropped fuelbundle.If the droppedfuelbundle occurred inthe Spent FuelPool andcaused thishigh radiation while level theplant was operating atpower, EOP-5 entry would berequired.AOP-44 wouldthen beexecuted in parallel with EOP-5.
