SQ 12/02/05 - deleted ", Section 2.8," from stem to avoid inference that memory or knowledge of the specific section was expected. Replaced "Drywell Fans and Drywell Coolers" with "Drywell Cooler and Fans" to conform with SSES vernacular and SSC configuration (generally consider a single component - original wording implied two separate components).SQ 12/06/05 - changed "Cooler" to "Coolers"SRONRC K/A GenericSystemNumberROCFR LinkSROAnswers: A B C DReferences Provided to A pplicant: GXJ THF RJCSSES 30Question Number:SSES Unit 1 is at full power.

VALID DISTRACTOR: Correct Power and Level changeCHOICE (D) - YESSteam Flow RISES cause HPCI Turbine Operating.Therefore, RPV pressure drops caused by ST rise.
Pressure drop causes power rises due to colder FW.
RPV Water Level will rise because FW now > ST. Stable when Level Error offsets Flow ErrorTotal Steam Flow will rise because now have additional steam flow pathIndicated FW Flow lowers to create the Flow Error that offsets Level Error.

CFR LinkComments and Question Modification History1. Gil 09/26/05 - could not validate with enclosed references. Note for justification "A" Power increases due to lowering feedwater temperature with HPCI injection.
R: Low risk of error because it is drawn from SSES Exam Bank and is theoretical rather than plant specific.2. Todd 09/30/05 - changed "INITIAL to FINAL" to "INITIAL change from SS"
: 3. SQ 10/14/05 - moved "Thermal Power will RISE" from choices to stem.
SQ 11/14/05 - no comments during validation week.SQ 12/02/05 - edited stem and distractors for better readability and accuracy. Specifics: added condition that FWLCS in 3-Element Average to ensure no argument over how FWLCS responds / asked condition of the plant 1 min after HPCI initiates to avoid arguments over ST v. LT changes and conditions / deleted "Thermal power will RIS and . . ." from stem / replaced verbs LOWER and RISE with adjectives be LOWER and be HIGHER / added "Actual" to each choice specify which steam flow.SQ 12/05/05 - SSES Training Staff confirmed that the simulator response supports the correct answer.

CThe Rod Worth Minimzer (RWM) permits withdrawal of multiple rods if the Control Room Operator selects "Rod Test" at the RWM Main Display.
D#5729719 SRO ROQuestion ID:NewOri gin:Memory Level 57Question Number:
JustificationCHOICE (A) - NoWRONG: This is NOT an automatic bypass VALID DISTRACTOR: Applicant could reasonably believe this to be true given that a "Refuel Position One-Rod-Out" interlock exists.CHOICE (B) - YESRWM Keylock Bypass Switch can only be used in the following two instances:The RWM Bypass Switch can be used by the operator to override active RWM rod blocks during any operating condition. There are administrative controls regarding the use of the RWM Bypass function in NDAP-QA-0338 (Reactivity Management and Control Program), Technical Specifications and Emergency Operating Procedures (EOPs). NDAP-QA-0338 permits bypassing for Special Tests. This is not a Special Test.Per SSES, this is not true - showed NRC where in SO-156-001, BYPASS is permitted.During a failure to SCRAM (ATWS) condition, execution of EOPs EO-000-113, "Level/Power Control" in the section for Control Rod Insertion, there is a step requiring this switch to be placed in the bypass position. This is not an EOP directed activityVALID DISTRACTOR: This would work but is ADMINISTRATIVELY impermissible.CHOICE (C) - NO CHOICE (D) - NOCauses a SELECT ERROR, INSERT BLOCK, WITHDRAW BLOCK - only works for ONE rod.
References TM-OP-031D TS 3.9.2 OP-131-001 NDAP-QA-0338
 
SO-156-003
 
GO-100-006Comments and Question Modification HistoryGil 09/26/05 - K/A mismatch. The question is about system interlocks, not administrative requirements.  "A" and "D" look implausible to me. RWM has to work in RUN. Everyone should know only one rod can be withdrawn in REFUEL.
R: need to beef up link to Administrative requirements. Disagree on plausibility of A and D. AUTO bypass is plausible if you understand that the RWM is not the primary means of enforcing the one rod out requirement. D is weaker but permits psychometric balance. Also somewhat plausible if you know that the RWM can be bypassed and that bypassing it allows multiple rods to be moved. Only error is method of bypassing.Satisfied with "A". Gil is not satisfied that this addresses the "administrative requirements" associated with refueling. However, the K/A requires a nexus between the RWM and refueling administrative requirements. The ROD TEST function is the only nexus I am aware of. Therefore, added second part of question concerning ONE-ROD-OUT Interlock functional test.09/28/05: SSES is considering how to better include administrative requirements.
Todd 10/05/05 - may not be RO unless L.O. exists to memorize test frequency. R - deleted second part of question concerning TSS frequency.Returning to original concept - nexus between RWM and Refueling Admin - this hits it by testing the Applicant's knowledge of the RWM Keylock Bypass Switch. Use of the keylock is ADMINSTRATIVELY prohibited.SQ 11/14/05 - inserted "only" into distractor "C".SQ 12/02/05 - substantive changes that may drive the question off the original K/A. Saved original as 571. Saved distractor "C" from "The Rod Worth Minimzer (RWM) permits withdrawal of only a single rod if the Control Room Operator selects "Rod Test" at the RWM Main Display." to "The Tod Worth Minimzer (RWM) is AUTOMATICALLY BYPASSED when the Reactor Mode Switch is in REFUEL."SQ 12/06/05 - change "The Tod Worth Minimzer" to "The Rod Worth Minimzer "Answers: A B C DReferences Provided to A pplicant: GXJ THF RJCSSES 57Question Number:2010 06NRC K/A S ystem/E/ASystemNumberROCFR LinkSRO2.2Equipment Control2.2.262.53.7Knowledge of refueling administrative requirements.NRC K/A GenericSystemNumberROCFR LinkSRO}}

JustificationCHOICE (A) - NoWRONG: This is NOT an automatic bypass VALID DISTRACTOR: Applicant could reasonably believe this to be true given that a "Refuel Position One-Rod-Out" interlock exists.CHOICE (B) - YESRWM Keylock Bypass Switch can only be used in the following two instances:The RWM Bypass Switch can be used by the operator to override active RWM rod blocks during any operating condition. There are administrative controls regarding the use of the RWM Bypass function in NDAP-QA-0338 (Reactivity Management and Control Program), Technical Specifications and Emergency Operating Procedures (EOPs). NDAP-QA-0338 permits bypassing for Special Tests. This is not a Special Test.Per SSES, this is not true - showed NRC where in SO-156-001, BYPASS is permitted.During a failure to SCRAM (ATWS) condition, execution of EOPs EO-000-113, "Level/Power Control" in the section for Control Rod Insertion, there is a step requiring this switch to be placed in the bypass position. This is not an EOP directed activityVALID DISTRACTOR: This would work but is ADMINISTRATIVELY impermissible.CHOICE (C) - NO CHOICE (D) - NOCauses a SELECT ERROR, INSERT BLOCK, WITHDRAW BLOCK - only works for ONE rod.

GO-100-006Comments and Question Modification HistoryGil 09/26/05 - K/A mismatch. The question is about system interlocks, not administrative requirements. "A" and "D" look implausible to me. RWM has to work in RUN. Everyone should know only one rod can be withdrawn in REFUEL.

R: need to beef up link to Administrative requirements. Disagree on plausibility of A and D. AUTO bypass is plausible if you understand that the RWM is not the primary means of enforcing the one rod out requirement. D is weaker but permits psychometric balance. Also somewhat plausible if you know that the RWM can be bypassed and that bypassing it allows multiple rods to be moved. Only error is method of bypassing.Satisfied with "A". Gil is not satisfied that this addresses the "administrative requirements" associated with refueling. However, the K/A requires a nexus between the RWM and refueling administrative requirements. The ROD TEST function is the only nexus I am aware of. Therefore, added second part of question concerning ONE-ROD-OUT Interlock functional test.09/28/05: SSES is considering how to better include administrative requirements.

Todd 10/05/05 - may not be RO unless L.O. exists to memorize test frequency. R - deleted second part of question concerning TSS frequency.Returning to original concept - nexus between RWM and Refueling Admin - this hits it by testing the Applicant's knowledge of the RWM Keylock Bypass Switch. Use of the keylock is ADMINSTRATIVELY prohibited.SQ 11/14/05 - inserted "only" into distractor "C".SQ 12/02/05 - substantive changes that may drive the question off the original K/A.
