DATE ISSUED: l 9/10/87 Advisory Comittee on Reactor Safeguards oe ypM Regional Programs Subcommittee Meeting Minutes August 28, 1987 Walnut Creek, CA PURPOSE: The purpose of the meeting was to review the activities under the control of the NRC Region V Office.
ATTENDEES: Principal meeting attendees included:
ACRS NRC F. Remick, Chairman R. Faulkenberry, Region V C. Michelson, Member K. Hamel, Region V D. Moeller, Member D. Kirsch, Region V G. Reed, Member R. Scarano, Region V C. Wylie, Member A. Chaffee, Region V P. Boehnert, DF0 J. Crews, Region V R. Fish, Region V A. Johnson, Region V R. Montgomery, Region V R. Pate, Region V R. Thomas, Region V G. Yukas, Region V R. Hernan, NRR MEETING HIGHLIGHTS, AGREEMENTS AND REQUESTS
- 1. The meeting was convened at 8:30 am. Dr. Remick expressed the Subcomittee's appreciation for the invitation to the Region V Office. He also noted that the Comission had asked the ACRS to become mora cognizant of the operation of nuclear power plants. In response to this request, and with the realization that the regional offices are a prime source of information on operating DESIGNATED ORIGINAL 2S22 Cert' .d By _

- ,e Regional Programs Mtg Minutes August 28, 1987 plants, the Regional Programs Subcommittee was established and held its first meeting at the Region III Offices. The Chairman said the Subconunittee is here to learn and no "hidden agenda" for this Meeting exists.
Mr. R. Faulkenberry (Region V Deputy Director) welcomed the Subcom-mittee to Region V. He discussed the first agenda topic on Region V Operations. The Region V. geographic region was noted (Fig.1).
With the exception of Alaska and Hawaii, all states are Agreement I States. The Region also has responsibility for the Pacific Trust l
Territories. In response to Dr. Remick, Mr. Faulkenberry said the Region is not involved with regulation of the Beatty Nevada low level waste site. It was also noted that the proposed California LLW site will be a State License. Figure 2 lists the number and type of Licensees. In response to Dr. Remick, NRC said the Region does oversee the "mothballed" status of the WPPSS Units.
Figure 3 details the responsibilities of Region V. Mr.
Faulkenberry noted that additional activity on licensing actions for operating plants may be transferred to the Regions. Mr. Reed i expressed concern with the AIT process, noting that there is a lack of diligence in identifying the real root cause(s) of incidents.
Mr. Michelson asked what the Region saw the mission of an AIT to be. Mr. J. Crews indicated that the goal was to determine root cause and corrective actions for a given event. Mr. Michelson said the AITs he's seen didn't leave the above impression, i.e., they're more like inspection reports. Mr. Faulkenberry agreed the AITs may look like inspection reports, but the Region believes they should be similar to the IIT approach.
Figure 4 outlines the Region V organization. For FY 88, they are allotted 102 FTE's.
, ..a '
Regional Programs Mtg Minutes August 28, 1987 Mr. Faulkenberry discussed the activities unique to Region V.
These activities include:
(1) Heavy load of resident sites with inspectors.
(2) Increased use of team inspections.
(3) Routine meetings with Licensee Management.
(4) Strong promotion of problem identification:
- Weekly Sr. Resident call to Regional Administrator
- Inspector / supervisor identified independent inspection.
(5) Strong dedication to use of operating plans, master inspection plans and management information reports.
Referring to Item 1, Mr. Michelson asked how Resident Inspector (RI) "capture" (loss of objectivity) is avoided. NRC said the use of a "buddy system" and close oversight of the RI's by the Reg. ion avoids this. The key means to avoid capture is by good supervision of each RI. In response to Mr. Reed, Mr. Faulkenberry said RI's have been recruited from Officers of the nuclear navy, college graduates, etc. All Region V inspectors are college degreed. Mr.
Reed expressed concern with the emphasis on college degreed individuals. In response to Mr. Michelson, Region V said the RI turnover rate is low ( ~ 3%).
Current Region V initiatives include: (1) improve overall perfor-mance of power reactor licensees /e.g., reduce number of scrams, (2) promote. licensee implementation of thorough, high quality events review programs (e.g., root cause analysis and correction program
e 1
(
s Regional Programs Mtg Minutes August 28, 1987 including human factors considerations), (3) encourage licensee self-critical attitude and assessment toward plant operations, and (4) improve overall quality of engineering support activities. Mr.
Michelson asked how the Region keeps abreast of problems in other Regions. Mr. Faulkenberry said they and the other Regions parti-cipate in the weekly Operator Reactor Events Briefing phone con-ference with Headquarters to discuss issues / events of concern.
Regarding Item 4 above, the Region indicated that the Agency has (belatedly) come to realize the importance of plant engineering support activities. In response to Mr. Wylie, Mr. Faulkenberry said NRC believes they have captured the Licensee's attention in this matter. Many Licensees have taken actions in response to Region concerns to tighten up their activities here. In response to Mr. Michelson, Mr. Crews indicated that the Licensees have taken steps to utilize feedback from operating experience vis-a-vis the AEOD Report on this Issue. Mr. Xirsch noted that plant technical specifications require Licensees to evaluate operating experience, though he acknowledged the lack of vigor on the Licensees' part in the past for this activity.
Major ongoing Issues at Region V are shown on. figure 5. Addressing :
the issue of QA concerns, Mr. Faulkenberry said he believes the real issue is a lack of technically competent people in the QA area. In response to Mr. Reed's concern that QA inspectors can (and should) be production personnel, Mr. Kirsch said he would be concerned with an arrangement where the QA inspector is not di-vorced from production activities (i.e., the opportunity for "cheating" is too great).
Addressing concerns with regulatory consistency among Regions, Mr.
Faulkenberry said there is some inconsistency and its unavoidable.
But through a series of actions (Fig. 6), steps are taken to assure that the Region is reasonably consistent in its activities. Mr.
Regional Programs Mtg Minutes August 28, 1987 Michelson noted a particular problem with lack of guidance on inspection of chillers (chilled water systems). Mr. Kirsch agreed there's a lack of guidance here but said the Region has had in-stances where a bad situation with a Licensee's (SCE) chiller system was found on inspection. The Licensee corrected the problem and the Region is disseminating this event to the other sites in the Region for followup. Mr. Michelson asked how fire protection is handled. Mr. Kirsch said Region V has a dedicated inspector for fire protection activities who rotates among the plants.
- 2. The status of Region V Reactor Operations Branch activities was reviewed by D. Kirsch. He began by discussing the Region's problem plant - Rancho Seco. Figures 7-9 detail the problems and correc- l tive changes underway. Mr. Kirsch said the key problem was the management's willingness to do only the absolute minimum necessary l to meet NRC requirements. They were also not aggressive in ad-dressing operational problems as they arose. Mr. Reed, citing TVA's problems, asked if the Region could give any insight to the problems seen in public vs private utilities. Mr. Kirsch indicated j that often the line responsibilities at public utilities are not as well defined as at private ones but that doesn't explain the whole I problem. Further discussion brought out the po, int that at SMUD, ,
there were competent people but their numbers were so few that the workload overwhelmed them.
Dr. Moeller asked if J. Martin's management conferences helped get to the above problems. Mr. Kirsch said Martin did get their attention, particularly at a NRC/SMUD Board meeting in late 83 -
early 84. Asked why the Region took no action between 1984 and late 1986 (cooldown transient). Mr. Scarano noted that absent a specific violation or incident, the SMUD Board's attitude was "we don't have a problem," and the Region felt they really couldn't move on them. Mr. Reed asked if NRC had made SMUD aware of the
e e Regional Programs Mtg Minutes August 28, 1987 challenge of B&W plant operation. Mr. Scarano indicated that there was an attitude of superiority at the Utility that prevented good communication.
Turning to the issue of plant maintenance programs, Mr. Kirsch said the Agency is drafting a Commission policy Paper on this topic, and a PI for Maintenance is being developed. INP0 and NUMARC are also active in this area. In response to Mr. Reed, Mr. Kirsch noted some Licensees (e.g., PG&E & SCE) are using aptitude testing in the hiring of maintenance and other personnel.
Chief maintenance related problems seen at Region V plants that were noted included: (1) No reliable, objective measures of plant-specific maintenance performance, therefore needed maintenanceisoftennotaccomplishedorperformedeffectively,(2) failures resulting from improper maintenance, (3) frequently inadequate maintenance / operations interface which contributes to personnel error, (4) maintenance activities and component failures which result in safety system challenges, and (5) maintenance is a major contributor to personnel occupational radiation exposure.
M.r. Michelson asked what actions the Region has taken vis-a-vis -
valve problems. Mr. Kirsch said a Contractor has been hired to inspect Licensees actions vis ASME Section 11 requirements. In addition, the "lessons learned" from valve related incidents have been incorporated into the agenda of Team Inspections for plants in the Region. Dr. Remick asked if Region V Licensees are using M0 VATS testing. Mr. Kirsch said PG&E is using a Program similar to M0 VATS, others are using it directly. The Region is favorably impressed with this technique.
l Regional Programs Mtg Minutes August 28, 1987 l l
l I
Dr. Remick asked how the maintenance backlog of Region V plants compares with other US plants. Region V said a big backlog isn't necessarily bad - unless there is a big backlog in safety related systems. If a careful priority of needed maintenance is developed, l
then the Region is comfortable. Dr. Remick noted the concept of '
maintenance backlog is unheard of at Japanese plants, but also said l that the cost for this approach is substantial. In response to Mr.
Michelson, Mr. Kirsch indicated that routine tours of a plant !
generally give one an impression of the overall status of their maintenance Program. The PI Program also helps here.
l Dr. Remick asked the Region to address the issue of safety con-science for a plant and where this conscience would (should) reside. He noted the result of a Human Factors Subconnittee meeting on this issue and asked if the Region feels comfortable !
that there is such a conscience at Region V plants. Mr. Kirsch said he believes the Licensees do put "safety first", albeit the problems seen at Ranch Seco. SCE also had problems here very early on. Mr. Kirsch said that unless the Licensees are being self critical, and are asking tough questions of themselves, the right attitude isn't there. Region V relies largely on the periodic NRC/ Licensee Management meetings to assure the proper attitude is -
evident. The Region's experience is that a safety conscience must be evident down through the entire Organization. Key to this, is clear lines of communication and feedback on job tasks. Mr. Crews echoed the belief that top /down feedback is essential to assure safety conscience.
- 3. R. Pate reviewed the operator licensing Program. The emphasis of his presentation was on the impact of the new 10 CFR Part 55 revision, and the consistency of examination among the Regions.
Key points noted were:
l Regional Programs Mtg Minutes August 28, 1987
- Until fairly recently, little attention was given to operator requalification examinations by either NRC or the Licensees.
- Region V has met all requirements for requalification exams.
With the exception of Palo Verde, all exams given in FY 87 to the Region V Licensees resulted in satisfactory pass / fail rates. The Palo Verde Training Program is now under NRC review for corrective action.
l
- In response to Dr. Remick, Mr. Pate said NRC has not been able l to attract SR0 experienced operator examiners because of government salary limitations and working conditions (e.g.,
extensive travel). NRC's goal is to have all exams conducted by NRC personnel. Currently, 10% of this effort is conducted by Contractor personnel.
- Appeals by operators failing exams have been increasing.
Appeals are coming from people even if they badly fail an l exam. Subsequently, the appeal process has become lengthly and complex. In response to Dr. Remick, Mr. Pate said the Region V pass rate has been running about the national average. Mr. Pate also said the impact of the new Part 55 and the INP0 Accreditation Program have been positive for Licensee's training Programs (i.e., programs have been upgraded). Dr. Remick said he has heard the operator exam Programs have been used to "punish" recalcitrant Licensees and asked for coment. Mr. Pate indicated that the exam form used should preclude such a problem.
Dr. Moeller noted that his experience in developing examina-tions showed that an evaluation of a prospective candidate's educational background was helpful in evaluating the value of the educational institution the person attended. He asked if
- l l
l Regional ~ Programs Mtg Minutes August 28, 1987 NRC reviews their exams for such information. NRC responded in the negative but said they do monitor for any perjorative 1 trends seen in the exams (e.g., all or most testees fail a givenquestionorsetofquestions).
- In response to Mt . Michelson, Mr. Pate said there is no effort made to try to correlate a given operator's error rate on the job with examination performance.
- Region V suggestions for improvement of the examination procedure included:
- Increased facility participation in development of the exam question bank
- Reduce the number of repeat questions on examination
- Improve the quality of questions (e.g. more objective questions)
- Clearer definition of pass / fail criteria for the oral examination (currently, it relies on the judgment of the examiner). !
- 4. The status of radiation protection programs at Region V Licensee i plants was reviewed by G. Yukas. Points noted include:
- Analysis of Licensee's fuel performance indicates that CE fuel has evidenced problems via-a-vis fuel failures (Figs.10-12).
Generally though, most Region V Licensees are operating within the radiological release limits. It was also noted that in 1986 the I-131 dose-equivalent for BWR's was a factor of 10 less than for PWR's. Details of the Rancho Seco effluent I
Regional Programs Mtg Minutes August 28, 1987 release incident were cited to illustrate the fact that substantial dose pathways to man can exist through the lack of responsible management.
- The recent concern with hat fuel particles was noted. Events were cited at Trojan and San Onofre to illustrate the problem.
' Palo Verde has an occupational dose problem due to high amounts of activated antimony from the RCP bearings. A signi', want faction (N60%) of their occupational dose is l
being attributed to this problem. I i
- Key conclusions cited were:
l l
- The nuclear powr industry can do a better job of con-trolling radioactive material.
- Utilization of new technologies, while providing better information and control, requires careful review and independent verification.
l
- The NRC inspection process is a critical element in the safety conscience of the industry.
- In response to Mr. Reed, Mr. Yakas said the Region V orga-nization does challenge the Licensee's plant design basis if evidence points to this as a problem,
- 5. The topic of plant Safeguards Programs was addressed in a question I and answer format by Mr. R. Montgomery (Region V).
Mr. Reed said he feels the issue of plant security has resulted in an adversarial atmosphere at many plants, due to the distrust of security people and the "militarilization" of plant security.
I
a **
l Regional Programs Mtg Minutes August 28, 1987 i
Montgomery agreed and said he had seen an attitude of "us vs them" -
at some plants. In his opinion, the management were seen to blame for this. The Region has fostered the attitude among the Licensees i that "security is everyone's problem." Mr. Reed also opined that the "military mind" needs to be tempered by real world considerations of workplace relationships.
Mr. Michelson asked for connent on the tradeoffs on plant security i versus access to vital equipment in emergencies. The Region noted that this issue has been studied and Licensees are evaluated on steps they have taken to assure timely access to needed equipment.
Mr. Michelson noted the incident at Surry (feedline rupture) which caused a plant-wide failure in the access card reader system and !
asked if the Region had evaluated the lessons learned here. The Region was unable to determine what actions (if any) had be :n taken. Mr. Faulkenberry said he would research this question to determine what action (s) is needed.
- 6. The fitness for duty (FFD) issue for Licensees was reviewed by R.
Scarano. He noted that this Program is under development for Licensees, and the Commission has deferred Rulemaking pending ;
evaluation of Industry efforts. The Comission is scheduled to l review this Issue in Spring 1988.
I Figures 13-14 show the results of FFD drug tests for the Region V plants. Discussion indicated that the specifics of each Licensees' !
program varies significantly, particularly in the area of disci-plinary actions taken for instances of drug use. None of the Licensees' Programs have true random testing procedures- (i.e.,
l scheduling of the tests is always known before hand). The pervasive use of drugs in our society means that there is almost continuous investigation of drug use at some U.S. plant. !
l l
, - I l
Regional Programs Mtg Minutes August 28, 1987 In response to Dr. Remick, Mr. Faulkenberry said implementation of the Commission's FFD program has been delayed for v 6 months until the Department of HHS guidelines on drug testing procedures are received and implemented.
- 7. D. Moeller noted for the issue of emergency preparedness that a recent study has shown that sheltering is usually preferable over evacuation, given a ma,jor release. He asked if the Region had any comment. Mr. R. Fish said he was unaware of this information. He I further noted NRC urges precautionary evacuation if possible. Mr.
Fish agreed that if the situation arose, and sheltering appeared that best option, they would so recommend.
In response to Dr. Moeller, the Region indicated that ACRS Letters are not widely disseminated in the Office.
Mr. Fish noted that nuclear emergency plans have been used for other emergency incidents (heavy snow, brush fires, etc.). Dr.
Moeller asked if the Region has ever had any input into the NRC i research Program. The Region responded that they have had input to j
the occupational health and radiation protection Program specif-ically, and there have been RES inquires to the Region in other '
areas as well.

- 8. J. Crews discussed the AIT conducted at Diablo Canyon following the loss of RHR on April 10, 1987 at Unit 2. Mr. Crews was a member of the AIT that investigated the incident. Key points noted were: ,
- Details of the event were noted and the scope of the AIT's activities were detailed. The AIT concluded that mid-loop operation was not considered in the plant's RCS design bases; nor was mid-loop operation analyzed in this (or any) plant's SAR. A 50.54(f) Letter has been issued to address the concern of an unanalyzed operational mode.
Regional Programs Mtg Minutes August 28, 1987
- Mr. Reed noted that earlier plants were equipped with vents on the SG tubesheets which allow one to avoid half loop opera-tion. Mr. Crews noted that they ~also could have avoided half-loop operation if the geometry of the RCS has been better considered. (Diable's RCS geometry prohibits a controlled SG tubedrain-down.) Mr. Reed urged the Region to require design changes in cases like this to avoid potentially unsafe modes:
of operation.
- 9. The SALP and PI Programs were discussed by A. Chaffee. Details of theSALPeffortwerenoted(Figures'15-19). While the SALPs are considered useful as a motivator to Licensees (primarily because the results are made public), they are quite resource intensive for NRC('v300 manhours / site). It was also noted that'the number of voting Members on the SALP Board may be reduced.
In response to Dr. Remick, Mr. Chaffee said that a Licensee's attitude is generally taken into account when assigning SALP ratings.
The history of the SALPs for Region V plants shows the plants with the best and worst SALPs are Diablo Canyon and Rancho Seco, respec- -
tively. In response to Dr. Remick, Mr. Xirsch indicated that Licensees in Region V are very supportive of SALP. They see it as an effective tool to help improve performance. Mr.Hernan(NRR) said his experience is that most Licensees respect the SALP. process as being fair.
In response to Dr. Moeller, Mr. Kirsch indicated that he takes pains to assure the Region V SALPs are in basic conformance with the SALPs of other Regions.
Regional Programs Mtg Minutes August 28, 1987 Mr. Chaffee discussed the Performance Indicator (PI) Program.
Currently, there are seven PIs (Fig. 20). Region V has a procedure for process and review of the PIs for their plants. If one of their plants is in the "worst 10" category, the Regional Adminis-trator is apprised, and the affected Licensee is called in for a consultation as well.
- 10. The impact of PVC actions on Region V Licensee performance was discussed. Figures 21-23 provide details. The California Plants (Diablo Canyon and SONGS) have been significantly impacted. Diablo may be disallowed a significant fraction of its costs ($4 B of $5 +
B). The PVC is squeezing them vis-a-vis operating costs as well.
NRC has not seen any adverse impact on Diablo's operations to date.
SONGS has had $265 M of its $2.5 B capital cost disallowed. In addition & 10% of Units' 2 and 3 operating budget has been disal-lowed for the coming year. Unit 1 was limited to a $200 M expendi-ture for capital expenses over the next three operating cycles.
This squeeze on costs has resulted in the Licensee's balking on installation of a dedicated HPCI system via a prior comitment to do so.
- 11. Prior to adjournment, Dr. Remick thanked Mr. Faulkenberry and the Region V representatives for a set of excellent presentations. He said the meeting was very interesting and hoped the Region found the meeting as useful as did the Subcomittee. Mr. Reed said he was impressed with the knowledge and competence of the presenters.
Mr. Faulkenberry said the meeting was indeed worthwhile from the Region's standpoint and suggested that the Subcommittee visit again in the not-too-distant future.
- 12. The meeting was adjourned at 4:50 p.m.
