EXECUTIVE SUMMARY Limerick Generating Station Examination Report No. 50-352,353/99-301
Operations l e Five RO applicants and four SRO applicants were administered initial licensing exams.
One SRO applicant failed the written test but passed all other portions of the exam. One RO applicant failed the category B operating test but passed all other portions of the exam. All other applicants successfully passed all portions of the exam.
. e Positive observations were noted on the simulator test in the area of communications and teamwork. However, three of nine applicants exhibited unsatisfactory individual knowledge of the reactor automatic depresssurization system indicating a potential problem in the initial operator program.
i e Overall, the as-submitted examination material was acceptable with some exceptions.
Five of 125 written exam questions required revision due to either being too easy or not evaluating at the appropriate licensed level. Additionally, the operating test contained one JPM out of 20 which was also too easy and required replacement. Facility personnel subsequently incorporated changes in the final exams. Post-exam facility comments reflected needed technical corrections for five of the written exam questions, and also indicated a lack of thorough review on those questions by the facility during the examination preparation phase.
e The facility used an examination preparation team of experienced instructors who assisted the NRC examiners in an exceptional manner.

l Report Details Operations 06 Operator Training and Qualifications 05.1 Reactor Ooerator and Senior Reactor Ooerator initial Exams a. Scope The NRC examiners reviewed the written and operating initial examinations submitted by the facility staff to ensure that they were prepared and developed in accordance with the guidelines of the " Examination Standards for Power Reactors"_ (NUREG-1021, interim Revision 8). The review was conducted both in the Region 1 office and at the Limerick training facility. The NRC examiners administered the operating portion of the exam to all candidates. c The written exams were administered by the facility's training organization.
b. Observations and Findinos Gradino and Results The results of the exams are summarized below: SRO RQ Pass Fail Pass Fail ; i Written 3 1 5 0 Operating 4 0 4 1 Overall 3 1 4 1 The facility provided post-examination comments reflected technical corrections to five of j the written exam questions. The NRC accepted four of the comments and revised the answer key accordingly. The changes indicated also a lack of thorough review on those questions by the facility during the exam preparation phase. Attachment 1 is the NRC l staff resolution of facility post-examination comments (Attachment 2).
Examination Preoaration and Quality The written exams, job performance measures (JPMs) and simulator scenarios were developed by the facility using the guidelines of the examination standards. The exam development team was comprised of training and operations representatives. All individuals signed onto a security agreement once the development of the exam commenced. The NRC subsequently reviewed and approved all portions of the q proposed exams. '
I i
Five of 125 written exam questions required revision due to either being too easy or not evaluating at the appropriate licensed level. The operating test contained one JPM out I of 20'which was replaced also due to being too easy. In response to the written and I operating test comments, facility personnel subsequently incorporated changes in the final exams.
The facility used an examination preparation team of experienced instructors who j assisted the NRC examiners in an exceptional manner, Written Test Performance l The facility training department performed an analysis of questions missed on the written exam for generic weaknesses. The facility noted seven examples where four of the applicants missed the same question. The training staff subsequently determined the quedions met the guidance of NUREG 1021, Appendix B, and were technically . accurate. Facility staff stated they would review these questions with the applicants.
i This action was determined to be acceptable.
Operatina Test Administration and Performance l The applicants demonstrated good communications and teamwork during the simulator l !: exercises in both the routine and emergency portions of the exercise. Briefings were routinely conducted by the applicants when in the control room supervisor position. The briefings were well controlled and ensured that all personnel knew the plant (simulator) status. One RO applicant failed the category B operating portion of the exam and all other applicants performance were acceptable.
I One question on the operating test dealing with the reactor automatic depressurization system (ADS) was missed by three applicants out of nine. This question failure rate indicated a potential problem with the initial operator program dealing with knowledge of the ADS logic for opening the ADS valves. This issue was discussed with the licensee and they agreed to review the area, c. Conclusions Five RO applicants and four SRO applicants were administered initial licensing exams.
One SRO applicant failed the written examination but passed all other portions of the exam. One RO applicant failed the category B operating examination but passed all other portions of the exam. All other applicants successfully passed all portions of the exam.
Positive observations were noted on the simulator test in the area of communications and teamwork. However, three of nine applicants exhibited unsatisfactory individual knowledge of the reactor automatic depresssurization system indicating a potential problem in the initial operator program.

Post-exam facility
- comments reflected needed technical corrections for five of the written exam questions, and also indicated a lack of thorough review on those questions by the facility during the examination preparation phase.-
The facility used an examination preparation team of experienced instructors who assisted the NRC examiners in an exceptional manner.
08 ' Miscellaneous Operations issues During a review of the candidates' applications, the examiners determined that: 1) the candidates had performed the required number of significant reactivity control manipulations; 2) the candidates met eligibility guidelines of NUREG 1021 and Reg.
Guide 1.8 as applicable; and 3) the licensing basis documents for eligibility requirements (i.e., the Quality Assurance Plan, Technical Specifications, the Final Safety Analysis Report, and the licensed operator program requirements as accredited) were consistent.
The licensee is committed to ANSI /ANS 3.1-1978.
The eligibility requirements of one senior reactor operator instant (SROI) applicant were ; reviewed. With the assistance of the NRC program office regarding the acceptance of military reactor operator experience to fulfili experience requirements, the NRC staff ,
' determined that the eligibility requirements were met for the SROI in question.
X1 Exit Meeting Summary On March 19,1999, exam-related observations were discussed with the manager of Operations Training. The NRC expressed appreciation for the cooperation and assistance that was provided during both the preparation and exam week by the licensee's examination team.
There were no observed discrepancies between the simulator and the plant. Therefore, simulator fidel?y was not discussed at the exit meeting or in this report.

Attachment 1 - NRC RESOLUTION OF FACILITY COMMENTS SRO/RO #54 l Summary of Facility Comment The question asked which SRV's were available for pressure control given the conditions that the Unit 2 remote shutdown panel (RSP) was manned due to a fire in the MCR, high ' - drywell pressure existed, and Division 3 DC power was lost.
The facility stated that the question stem did not discriminate between automatic pressure control (overpressure lift setpoint reached) or manual pressure control.
Additionally, the facility stated, if the candidate assumed automatic pressure control,' then instrument air backup would not be required for any SRV's. Consequently, the facility recommended accepting either "a" or "c" as the correct answer.
Resolution of Facility Comment The NRC staff agreed with the facility's comment that, if the candidate assumed l automatic pressure control, SRV's are operable at their respective overpressure lift setpoints. The setpoint for the "N" SRV is 1170 psig. This SRV has controls at the remote shutdown panel. The other SRVs listed have a higher setpoint and some are not , controlled at the remote shutdown panel. With the reactor shut down, the heat removal capacity of the "N" SRV exceeds the decay heat load, and would be the controlling SRV in the automatic mode of operation. This would make answer"a" correct. If only manual controlis assumed, answer"c"is correct. Therefore, NRC staff accepted answers "a" and "c".
SRO/RO#58 Summarv of Facility Comment I The question asked why the Recirc pumps are required to be tripped during a loss of instrument air.
The facility provided the basis document for the loss of instrument air off-normal procedure, ON-199 Rev.14. The procedure stated that, upon the loss of instrument air, recire pump seal purge and motor airspace cooling will be lost; and, therefore, the recirc pumps must be tripped per procedure step 2.6.1. Consequently, the facility recommended accepting either "a" or "c" as the correct answer.
Resolution of Facility Comment The NRC staff accepted the facility's comment and revised the answer key to accept answers "a" and "c" as correct because the facility training staff provided a technical basis to support the recommendation.
__
Attachment 1 (Cont'd) NRC Resolution of Facility Comments RO #94 Summary of Facility Comment The question asked the MCR response to an alarming overhead a'nnunciator caused by an ongoing l&C test. Specifically, the performance of Main Steam Line Flow H gh channel B calibration functional test (ST-2-041-425-2) caused overhead annunciator ? MAIN STEAM LINE Hi FLOW" to alarm.
The facility stated that operations procedure OM-L-7.1, step 5.1.2, indicates that it is at ' the operator's discretion to permit non-operators to acknowledge MCR alarms, in which case, answer "c" is correct. The procedure also states an exception to this step in which only licensed personnel shall be permitted to acknowledge alarming RPS annunciators.
The " MAIN STEAM HI FLOW " trip units provide a Group 1 isolation signal which results in a RPS trip signal. Because of this relationship, a RO who treats the this alarm in the same fashion as an RPS alarm is taking reasonable and conservative action. Therefore, answer "a" is also correct.
Resolution of Facility Comment The question asks what is the _" required MCR response." In this case, the alarming annunciator is not a RPS alarm (defined as an overhead alarm tile with a RED triangle in the corner) and, therefore, by procedure can be acknowledged by other non-operations personnel with RO concurrence (answer"c"). While the RO is taking reasonable and conservative action by treating the main steam line alarm in the same fashion as a RPS alarm, it is NOT a requirement that only the RO be permitted to acknowledge the alarm (answer "a"). By procedure, the alarm may still be acknowledged by the l&C technician with RO concurrence, making answers "a" and "c" mutually exclusive. Therefore, the NRC staff denies the facility comment and accepts answer "c" as the only correct answer.
RO#96 Summary of Facility Comment The question asked to describe the status of core alterations if the refuel bridge has lost communications with the MCR RO while removing a bundle from the core.
The facility stated that the question stem did not stipulate at what point in the fuel movement sequence the communications failure occurred. Therefore, answer "d," that stated " core alterations must be suspended immediately and the bundle must not be raised or lowered," would also be correct, if the candidate assumed the failure occurred I just after grappling the bundle in the core.
i
Attachment 1 (Cont'd) NRC Resolution of Facility Comments Resolution of Facility Comment The NRC staff accepted the facility's comment and revised the answer key to accept answers "b" and "d" as correct because the facility training staff provided a procedural basis to support the recommendation.
RO #98 Summarv of Facility Comment The question asked to describe the action to be taken after exiting a posted contamination area and observing during a whole body frisk that your highest reading was 120 cpm above background readings.
The facility stated that an additional correct answer would be to reperform the frisk, and if readings are unchanged, contact HP. This answer, as well as the original correct answer, is supported and described in procedure HP-C-818-1, Whole Body Frisking Method. Therefore, answers "b" and "d" are correct.
Resolution of Facility Comment The NRC staff reviewed Exhibit HP-C-818-1, Rev.4. A note at the top of procedure HP-C-818-1 and steps E. and F. suppo-t answer "b." Therefore, the NRC staff accepted the facility's comment and revised the answer key to accept answers "b" and "d" as correct.

a. *2A", *2C', or *2N' SRV b. *2S". *2M*, or *2K" SRV
'
c. *2N, MC", or *2N' SRV only after instrutnent Air backup d. *2S", *2M*, or *2K* SRV only after instrument Air backup
,
ANSWER: C REFERENCE: LOT-1563 FACILITY RECOMMENDATION: Accept A or C as correct JUSTIFICATION: Under the given conditions, SRVs 'A,* 'C," and *N* are operable for automatic (pressure) actuabon and will be ope.rable for manual operation from the Remote Shutdown Panel (RSP) after restoration of pneumatics. The question provides no restriction on the mode of pressure control to be consdered, and A or C is correct.
SRVs "S," "H," and *M* are also operable for pressure actuaten; however, choices "B," and *D* are incorrect for the following reasons 1. The stem of the question restricts the candidates' responses to those SRVs associated with the RSP. Only SRVs *A." *C," and *N* are associated with and indicate at the RSP, 2. The setpoet for the *N" SRV is 1170 psig and the setpont for the *S,""H," and *M" 4 SRVs is 1180 psig. With the reactor shut down, the heat removal capacity of the "N* SRV (870,000 LB/hr or 5.8%) exceeds the ex.WM decay heat load, it will lift and reduce pressure; preventing the *S,Q* and *M* SRVs from controlling pressure, and 3. Procedure SE-1. * REMOTE SHUTDOWN * stipulates in Step 4A.1 that the "A," *C," and 'N' SRVs ane the mode of pressure control.
~~ Choices "N and 'C' are the only correct answers.

.ON-119 LOSS OF INSTRUMENT AIR - BASES cu-1 i 1.0 SYMPTOMS 1.1 Both Instrument Air Header low pressure alarms.
BASIS Both Instrument Air Header. Iow pressure annunciators alarming (*18-B(C)-2) indicates 1 that both the *A and *B Instrument Air Headers are less than the alarm setpoint of 85 psig. Air systems redundancy has failed to maintain at least one source of Instrument I Air at normal pressure to critical plant valves and instrumentation. Consequently, plant stability is threatened.
1.2 Scram pilot air header low pressure alarm.
BASIS This alarm (*08-D-5) is indicative of a low Instrument Air header pressure. Pressure is sensed downstream of a pressure control valve which reduces normal Instrument Air pressure to 70 to 75 psig. 'This alarm annunciates at 65 psig.
2.0 OPERATOR ACTIONS, 2.1 -lE any of the follow'.ng compressors are not running, THEN START thom:
- *A Ins'trument Air Compressor l - *B instrument Air Compressor
-
Service Air Compressor BASIS These compressors should be running and loaded (automatically) at receiver pressures less than 97 psig. A compressor not running may be a failure to auto start, and a manual start could restore Instrument Air pressure.
i
l ON-119 BASES, Rsv.14 Page 2 of 13 l DJD/RCB/BJL/ALC:cer 2.2 MONITOR the following instrument air pressure indications:
-
PI-15 *20A, "* A instrument Air Header Pressure" (PX), at *0C655
-
PI-15 *208, "*B Instrument Air Header Pressure" (PX), at *0C655 BASIS Pressure indicators PI-15 *20A(B) indicate instrument air pressure downstream of the instrument air dryers and are indicative of actual pressure on the instrument air header.
- Computer point G500 (C*130), "*A Instrument Air Receiver Lower Pressure"
-
Computer point G501 (C*131), "*B instrument Air Receiver Low Pressure" BASIS G500 and G501 change from NORMAL to LO at 80 psig as measured at the instrument air receivers. . These computer points can help determine if the loss of instrument air is resulting from a problem with the instrument air dryers or the instrument air compressor.

BASIS Reducing reactor power will reduce feedwater flow rate and provide the feed pump control system greater margin to maintain adequate feed to the reactor should feed pump or condensate pump minimum flow valves start to drift open on low instrument operating air pressure. Also, a reactor scram, should it occur, would be a less severe transient when initiated at a lower reactor power.

2.5.3 JE 'A(B) Instrument Air Dryer prefilter QB after filter differential pressures are greater than 5 psid, THEN PLACE appropriate standby filter in service per S15.6.E BASIS Clogged air dryer filters could be at fault. Valving into service the standby filters takes relatively little time.
2.5.4 CLOSE 15 *042, " Service Air Comp Air Receiver Outlet" (328-T1-217/357-T5-217).
BASIS Both Instrument Air receivers less than 70 psig should cause the automatic Service Air header isolation valve to close, dedicating the output of the Service Air compressor to the Instrument Air system. Should a fault exist downstream of the automatic isolation valve and that valve not fully close, Service Air system capacity as a backup source of air could be degraded.

l ON-119 BASES, Rav.14 Page 6 of 13 l DJD/RCB/BJL/ALC:eer NOTE 1. Following step assumes Service Air was backing up "A" instrument Air Header at time of pressure loss.
2. E Service Air was backing up "B" instrument Air header, THEN 15 *009A, " Service Air To "A" Inst Air Tie Viv," would be closed AND 15 *0098, " Service Air To "B" Inst Air Tie Vlv," would be opened.
2.5.5 E Service Air compressor is still operating AND both Instrument Air headers are depressurized, THEN PERFORM the following: 1. CLOSE 15 *009A(B), " Service Air To A(B) Inst Air Tie Viv" (328-T1-217/357-T5-217).
2. OPEN 15 *009B(A), " Service Air To B(A) Inst Air Tie Viv", in an attempt to repressurize the header (328-T1-217/357-TS-217).
I BASIS ] in the case of a failure of B(A) Instrument Air compressor and a coincident failure of A(B) j
. Instrument Air header (i.e. line break), it would be appropriate to isolate Service Air to !
the A(B) header and to valve it into the B(A) header. l
2.5.6 E Service Air compressor discharge pressure is greater than Instrument Air compressor discharge pressures, THEN OPEN 15 *027, " Service Air to Inst Air Tie Viv" (328-T1-217/357-T5-217).
BASIS Service air pressure should not be significantly greater than Instrument Air header pressure since the Service / Instrument Air header cross-tie check valve augments Service Air to the instrument Air header. However, if the cross-tie check valve was to malfunction (not open), Service Air pressure could be greater than Instrument Air pressure. Only in this situation should the cross-tie check valve be bypassed to restore the backup air supply to instrument Air.

BAS!S If all previous efforts to restore Instrument Air have failed, cross connection between the two Units may be considered. The possible adverse consequences to the non-affected
- Unit need to be carefully considered prior to cross connecting air systems. An operating Unit could be inadvertently tripped or otherwise unfavorably affected. The malfunction in the affected Unit air system must be identified and understood prior to considering this corrective action. Slowly opening cross connection valves while monitoring the non affected Unit air system performance should allow termination of the evolution if significant pressure losses or other non-desirable events occur.

Should the determination be made that instrument Air cannot be restored, the plant should be shutdown in a controlled fashion before Instrument Air loss degrades plant systems in a random unpredictable manner.
2.6.1 WHEN all control rods are inserted per GP-4, THEN TRIP both reactor recirculation MG sets.
BASIS The,drywell chilled water system shuts down, and the reactor recirculation pump mechanical seal purge supply isolation valves fail closed on a loss of Instrument Air. The i reactor recirc pumps are not needed when the reactor is shut down and should not be l operated without seal purge and motor airspace cooling. Also, the turbine building i
! - ventilation system shuts down on a loss of Instrument Air. This, in turn, would cause the reactor recirculation MG sets to trip on high air temperature.

BASIS The main condenser is not a maintainable heat sink without Instrument Air. The auxiliary boilers become inoperable, the offgas system drain valves fail closed, and the mechanical vacuum pump suction isolation valve fails closed on a loss of instrument Air. Isolating reactor pressure vessel steam protects the main turbine, condenser and associated auxiliary systems by forcing decay heat to be deposited in the suppression pool where the energy can be dissipated by systems not dependent upon Instrument Air.

BASIS Reactor building ventilation supply and exhaust dampers fail closed on a loss of instrument Air, tripping their respective fans. The recirculation and standby gas treatment systems should still function to maintain proper negative secondary containment pressure. The operator should monitor secondary containment pressure to ensure pressure is controlled within Technical Specifications requirements. ON-111, Loss Of Secondary Containment, provides the operator actions in the event secondary containment pressure can not be maintained.

This information is relevant as follows: e if the communications failure occurred just after grappling in the core or seating in the fuel pool, then the appropriate action is to stop all motion and not raise the bundle (canr.ot be lowered), and D is correct.
- If the communications failure occurred with the bundle hanging from the grapple between the core and fuel pool, then the appropriate action could be to maintain the current position or to continue to the fuel pool, and B or D is correct.
The action of placing a bundle in the safe condition does not exclude halting all bridge and mast movement and awaiting further direction. In comparing the actions in B and D for the given scenario, there are no adverse consequences for the additional restrictions imposed in D, and both B and D are correct.
