18 November 2005 From: Harry Balian To: File Subj: Record Retention of Rejected Questions These documents are the questions rejected during development of the Susquehanna Steam Electric Station December 2005 Operator Licensing Examination.
These documents are retained because some entries in the Comments and Question Modification History were not always carried over to the replacement questions.
Question Number: 21
- 2 1 1RO CSRO QwstionID: 29662 Origin: Mod Memory Level Given the following conditions:
- SSES Unit 1 recently entered Mode 4 to start a refueling outage following a 500 day run.
- SSES Unit 2 is in mode 1 at full power and flow.
- The station experiences a loss of Startup Transformer T-20.
- the Shift Manager has just declared an UNUSUAL EVENT.
Why has Shift Manager declared an UNUSUAL EVENT?
A CUI : Loss of All Offsite Power to Essential Busses for Greater than 15 Minutes.
B CU2: UNPLANNED Loss of Required DC Power for Greater than 15 Minutes.
C CU3: UNPLANNED Loss of Decay Heat Removal Capability with Irradiated Fuel in the RPV.
D MU1: Loss of all Offsite Power to Essential Busses for Greater than 15 Minutes.
Question Number: 21 References Provided to ADDliCant: J Justification CHOICE (A) - NO I
WRONG, requires loss of both T-10 AND T-20.
VALID DISTRACTOR: Loss of power c/b reasonable cause for entering the EAL CHOICE (6) - NO WRONG: requires loss of ALL vital DC power for >15 minutes.
VALID DISTRACTOR: Applicant may believe loss of T-20 causes loss of DC power.
CHOICE (C) - YES Applicant must recognize that loss of T-20 causes RPS Bus "8"to deenergize on SSES Unit 1. This causes PClS initiation which, subsequently, isolates the RHR SDC drop line. Finally, Applicant should recognize that decay heat load is high and an uncontrolled heat up could cause RCS temperature to rise above 200 degrees Fahrenheit. This is the entry condition for EAL CU3 per EP-TP-001 CHOICE (D) - NO WRONG: requires loss of both T-10 AND T-20.
VALID DISTRACTOR: Loss of power c/b reasonable cause for entering the EAL.

- 3. Gil 09/09/05 - concerned about WA match
- 4. Gil 09/26/05 - WA mismatch. Relationship between containment isolation and EAL?
R: on a loss of T-20, RPS buss "6"is deenergized. This causes Primary CTMT isolation including isolation of RHR in SDC mode. The successful Applicant must recognize the reason PClS isolated is the loss of RPS buss "B"and that the isolation interrupted SDC which must be restored to prevent entry into an EAL. If SDC not restored, the threshold for an EAL will be crossed.

- AR-106-001 (A08) GEN LOCKOUT RELAYS TRIP
- AR-106-001 (C04) STATOR COOLING WATER PUMP 1A-1B TRIP
- Generator Stator Cooling Water Pumps 1A and 1B are NOT running (both AMBER lights energized)
- Generator Stator Cooling Water control switch is selected to "1A-START 1B-RESERVE" What AUTOMATIC action will occur and why?
A Main TURBINE trip due to Generator negative phase sequence.
B Main TURBINE trip due to Generator Stator Cooling Water high conductivity.
C Main GENERATOR trip due to Generator Stator Cooling Water low pressure.
D Main GENERATOR trip due to Generator Neutral Overvoltage (59GN) fault.
Question Number: 52 Answers: I A IE d - 1 CJ-J References Provided to ADolicanI: 1-1 Justification
_ _ _ _ _ _ ~
I CHOICE (A) - NO WRONG: This will cause Generator trip but not the Stator Cooling water pump trips.
VALID DISTRACTOR: Plausible because a Negative Phase Sequence will cause GENERATOR trip.
CHOICE (B) - NO WRONG: No automatic turbine trip on high conductivity.
VALID DISTRACTOR: Plausible because Operators are expected to perform reactor scram / turbine trip if conductivity can not be maintained below 9.9. However, there is no automatic stator cooling or turbine trip on stator water conductivity. Moreover, the question calls for what would cause a GENERATOR trip v. TURBINE trip.
CHOICE (C) - NO WRONG: This is a TURBINE, not GENERATOR trip.
VALID DISTRACTOR: Plausible because low stator cooling water pressure (< 44 psig) will cause a TURBINE trip after a 70 second time delay (normal pressure is 50 to 65 psig). However, a simple pump trip is not expected to cause this condition because the resewe pump should start if low discharge pressure (first signal at < 102 psig, second signal at <
92 psig) is sensed at the discharge of the running pump. The stem indicates that the resewe pump would have started.
Moreover, the question calls for what would cause a GENERATOR trip v. TURBINE trip.

'_SRO QuestionID: 29584 Origin: New iIMemory Level Residual Heat Removal (RHR) loop "B" is running in the Suppression Pool Cooling mode of operation per EO-100-103, PC CONTROL. The Reactor Operator notices significant fluctuations in flow rate and motor amps on both RHR Pumps "B" and "D".
Which ONE of the following caused this?
A Minimum flow valve HV-151F0007B failed open.
B Safety Relief Valve (SRV) "S" stuck open.
C RHR Pump "B" discharge flow orifice FO-15100B is blocked.
D Clogged RHR Loop "B" suction strainer..
Question Number: 141 Justification I
Surveillance Requirement SR 3.5.1.7 Need to verify the procedure .done 09/07/05 by email DISTRACTOR (A):
Plausible because a failed open min flow valve will affect the pump by increasing flow rate and NPSH requirements. The pumps are rated at 3175 gpm @ at 290 psig. The rnin flow line is designed to pass the full rated flow of two pumps (6350 gpm). Therefore, opening the min flow line during a test could cause pump RUNOUT. However, the stem conditions describe CAVITATION.
DISTRACTOR (C):
Plausible because blocking the discharge path will affect the pump by increasing discharge pressure and reducing flow rate. However, this effect is inconsistent with indications of cavitation.
DISTRACTOR (D):
Plausible because this was a recent industty event. However, each pump has its own suction strainer. Therefore, two clogged strainers are required to make this true.

Surveillance Requirement SR 3.5.1.7 Need to verify the procedure - done 09/07/05 by email.
Plausible because a failed open min flow valve will affect the pump by increasing flowrate and NPSH requirements. The pumps are rated at 3175 gpm @ 290 psig. The min flow line is designed to pass the full rated flow of two pumps at I (6350 gpm). Therefore, opening the min flow line during a test could cause pump RUNOUT. However, the stem conditions describe CAVITATION.

Question Number: 181
- 18 I [ RO PSRO QuestknID: 29579 Origin: New Memory Level SSES Unit 1 has an Anticipated Transient Without Scram (ATWS). The control room operating crew initiate Standby Liquid Control (SBLC) per LQ/Q-3. You observe the following:
- 1P208A SBLC Pump RED indicating light ILLUMINATES,
- 1 P208B SBLC Pump RED indicating light does NOT illuminate,
- ONE SBLC SQUIB READY A-B White indicating light extinguishes,
- ONE SBLC SQUIB READY A-B White indicating light remains energized,
- SBLC SQUIB VALVES LOSS OF CKT CONTINUITY (A03) Energizes.
If initial SBLC Tank Level was 4742 gallons, what is the SHORTEST time until STANDBY LIQUID TANK HVLO LEVEL (C03) energizes at its setpoint of 4587 gallons?
A 2 minutes B 4 minutes C 8 minutes D 16 minutes
Question Number: 181 References Provided to ADDlicant: I
~
Justification I New - inspired by Browns Ferry 2 exam of September 2001 (Question ID 21039)
SSES requires both SBLC pumps to start to ensure reactor safety following an ATWS. The expected flowrate is approximately 86 gpm. In this case, the flowrate is one-half of expected (43 gpm) because one SBLC pump failed to start. The alarm will energize when 4742 less 4587 (1 55) gallons have been injected. This will occur in 155 divided by 43 or 3.6 minutes.
The failure of one SQUIB Valve to fire has no effect on the solution because the pumps discharge to a common header.
The common header then flows through two parallel SQUIB valves.
A - Plausible because this is the expected answer if both pumps inject through both SQUIB valves at 86 gpm
- Plausible if the Applicant believes that the failed SQUIB valve blocks SBLC flow to the RPV C - Plausible if the Applicant somehow concludes that the failed pump halves flowrate and that the failed SQUIB valve halves flowrate again.
D - Plausible if Applicant misapplies Pump laws to this problem References I

- / 43 I CRO CSRO QuestknID: 29613 Origin: New 3 MemoryLevel SSES lost all offsite power (LOOP). During the transient, a Main Steam (MS) line on SSES Unit 2 broke and caused Main Steam Isolation Valves (MSIV) to CLOSE. Subsequently, the control room is EVACUATED and you go to the SSES Unit 2 Remote Shutdown Panel (1C201). The following conditions now exist:
- BOTH the Upper and Lower Relay rooms are inaccessible.
- Drywell Pressure is 1.9 psig.
- Reactor Pressure Vessel (RPV) Pressure is cycling between 1,180 psig and 1,150 psig.
(1) What functional mode are the Safety Relief Valves (SRV) operating in?
(2) Which SRVs can be operated from the Remote Shutdown Panel given these conditions?
A (1) Overpressure SAFETY operation (2) PSV-241-FO13A, B and C B (1) Overpressure RELIEF operation (2) None C (1) Overpressure RELIEF operation (2) PSV-241-FO13A, B and C D (1) Overpressure SAFETY operation (2) None
Question Number: 431 Answers: 1 A 4;- D JL References Provided lo Amticant: I[_
Justification CHOICE (A) - NO I
WRONG: PSV-241-F013A, B and C not available because no CIG.
VALID DISTRACTOR: PSV-241-F013A, B and C are the three SRVs that can be operated at the RSD.
CHOICE (B) NO -
WRONG: RELIEF mode is incorrect - pressures too high VALID DISTRACTOR: mirror imaging CHOICE (C) - NO WRONG: RELIEF mode is incorrect - pressures too high VALID DISTRACTOR: PSV-241-F013A, B and C are the three SRVs that can be operated at the RSD.
CHOICE (D) - YES There are 16 SRVs. In the SAFETY mode, two SRVs open at 1175. six SRVs open at 1195 and eight SRVs open at 1205 psig. In the SAFETY mode, the SRVs close at 97% of set pressure. 97% of 1175 is 1140. 97% of 1195 is 1160.
Therefore, 1180 to 1150 is a reasonable expectation for RPV pressure in this condition.
That the SRVs are operating in the SAFETY mode is the first clue that the RELIEF mode of operation is not available.
The RELIEF mode requires 90#CIG and an electrical signal. For whatever reason, the RELIEF mode is not working because pressure is cycling well above the Relief Setpoints (2-1106, 4-1116, 4-1 126, 3-1 136, 3-1 146). DW pressure is above the 1.72 psig CTMT isolation setpoint. Therefore, the 90# CIG header is isolated and CIG is not available to operate the SRVs in the Relief mode. This fact gives the Applicant a conclusive explanation as to why the Relief mode is not working References TM-OP-083 1

- 1. Gil 09/26/05 - believes SRVs always operate in Overpresssure Relief mode before safety relief mode. This will deplete the air supply. Question may have NO correct answer if this is true.
R: The stem conditions state that pressure is cycling between 1180 and 1150. At these higher values, the SRVs have to be in the Safety mode because RPV pressures would be lower in the Relief mode. Applicant should be sufficiently familiar with the setpoints to recognize this.

WRONG. CLASS 1E buses are energized because EDGs are powering the ES buses.
VALID DISTRACTOR: Both NON-CLASS 1E have dedicated batteries but they are only good for 20 minutes CHOICE (B) - YES The 1E buses are energized from the EDGs via 4kV and 480VAC CHOICE (C) - No WRONG. Class 1 E buses are energized VALID DISTRACTOR: This IShow the NON-CLASS 1E buses respond to a loss of the preferred 480-VAC MCC CHOICE (D) - NO WRONG: NON-CLASS 1 E are NOT powered from station batteries (they have dedicated batteries)
VALID DISTRACTOR: Both 1E buses are energized and station batteries do have 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of power.

Comments and Question Modification History 1c 6XJ 0SSES Gil 09/26/05 - "A" and "C" not plausible with "all ...components operate as designed". That is, everyone should know 1E equipment will be energized.
Use a different term (RPS MG Set or Instrument AC Distribution Panel 1 Y216, etc) rather than "CLASS 1 E".
Answer B does not appear correct. The way I read the references the preferred will be lost for about 10 seconds and the UPS will run on DC. Then when the EDG energizes the bus the UPS will automatically shift back to preferred.
R: will revisit this question.
Added "one minute after" to expressly show question is asking for conditions after the transient.

During the ensuing transient, Reactor Recirculation Pump "B" trips. After the plant stabilizes, the following conditions exist:
- Reactor Power is 51%.
- Loop "A" total Jet Pump flow is 55E6 Ibm/hr (55,000,000 Ibm/hr).
- Loop "B" total Jet Pump flow is 20E6 Ibm/hr (20,000,000 Ibm/hr).
- Core Plate differential pressure (d/p) on NJP51 is 2.0 psid.

ON-104-203 Comments and Question Modification History 4 6XJ RJC Compare to question 29 - power supplies to RHR valves. May be redundant. However, kept both WAS because they were randomly selected and the pumps and valves are unique components.
Gil 09/26/05 - "A" does not appear correct per references. HV-1F024A is not on list in Attach C If all "A" designated Class 1E buses ONLY supply " A components (which is expected), then "B" and "D" are implausible.
R: will re-verify. Concerning plausibility, observe that the Loop A valves are powered from 18237.
HV-Ell-lF024A does appear in ON-104-203, Attachment E, Page 2 of 7 (page 19 of the procedure) as a load on MCC 18237.

For SSES Unit 2, the MSBWP is 02.
CHOICE (A) - NO WRONG: SSES Unit 2 MSBWP is 02. Here, 24 rods are at position 04.
VALID DISTRACTOR: Applicant could erroneously apply Unit 1 data to Unit 2. Good question on unit differences.
CHOICE (B) - NO WRONG: the Reactor can NOT be deemed shutdown under all conditions. . .
VALID DISTRACTOR: Applicant could erroneously believe that the Reactor is S/D but not assured to remain shutdown under all conditions . . .
CHOICE (C) - NO WRONG: the reactor can NOT be deemed to be SHUTDOWN.
VALID DISTRACTOR: Applicant could erroneously believe that the Reactor will remain S/D even though it's not currently declared S/D with more than rod above 00.

A RClC operation may continue to operate because the RClC turbine exhaust is within the Primary Containment Vent capacity.
B RClC operation must be isolated at the same time as HPCl to minimize Primary Containment pressure rise.
C RClC operation may continue ONLY if it is the LAST available source of high pressure coolant injection to ensure adequate core cooling.

Tough WA match. Alternative may be to present sequence of events and ask what could have caused it Gil 10/16/05 - Question is about what happens with decreasing vacuum. NOT a match to WA. Suggest a table of absolute pressure readings with time and ask when the various things wiull happen. In any event, RX will Scram on Turbine Trip >30% power.
R - This was an acceptable K/A match on another NRC exam. I see no difference between asking for the correct sequence of events and the suggested fix. Agree that the Rx will scram upon Turbine Trip. Question is asking if the Applicant recognizes that the heat sink is about to be lost and, therefore, it is best to preemptively stop the heat source .
