! 3.0 Quality Assurance Program Review

,

3.1 Audits Program l '~,

The licensee's Operations Quality Assurance procedure 0QA-XVIII-3,

! In-Plant Audit Program delineates methods and process for conducting

'

audits at Vermont. Yankee Nuclear Plant. Accordingly, the Yankee Nuclear Service Division QA Audit Group prepares audit schedule, and conducts QA program audits of operational activities. The auditors are qualified and certified-in.accordance with the procedure OQA-XVIII-1. The auditors prepare a comprehensive audit checklist to insure depth and continuity of audits. Subsequent to the conclusion of the audit, an audit report is

. generated and any'nonconformances are documented as audit findings. The audit group manager reviews and approves audit reports. The audit i

_

'

.

..

reports are then distributed to audited organization, cognizant plant disciplines, and the upper management, as applicable. The Operations-QA

-

. Group at the site conducts surveillances, and reaudits'to verify the implementation of audit finding correction action for the previously identified deficiencies. The Operation QA Group updates and issues Plant Audit' Discrepancies Status Reports bimonthly to the Yankee Nuclear Service Division QA Audit Group to indicate the status of the action item The inspector reviewed the QA audit schedule for the current calendar

~

year. 'The schedule covered all major QA-related activities such as design, modifications, purchase,' refueling, preventive maintenance,-

in-service testing, inspection, storage and handling, and corrective action. A review of the~ completed audit reports indicated that they were adequately planned, and conducted within_the targeted schedule. The audit checklists'were comprehensive and covered applicable aspects of 10 CFR 50, Appendix B criteria, other applicable-industry standards, and the licensee's commitments. The following completed audits were reviewed and found to be in compliance with the facility's procedural requirements:

VY-85-088,. Procurement / Material Control VY-85-11, Inspection and Test In accordance with the procedure OQA-XVIII-2, the-licensee is required to issue, within 30 days of the receipt of the audit report, a plant positio : report, and Manager of'0peration (M00) implementation directive to resolve audit finding and implement corrective action. The Audit VY-85-08B indicated 5 programmatic. discrepancies and 1 observation in the audited areas of~ station procurement, receipt' inspection, material control, and trainin It was noted that the manager of operation neither issued the implementation directive within 30 days, nor: requested an extension to the effect. As a result, the-audit finding corrective action was not implemented as of the conclusion of this inspection. The licensee's implementation of the corrective action-for the above audit finding is an unresolved item (50-271/86-20-01).

The audit finding corrective action implementation for audit VY-85-11 was adequate and timely. Three other audits are discussed in Section .2 QA/QC Interface The licensee is in the process of restructuring the station organizatio Accordingly, the plant services (previously administrative services)

department has been assigned to the plant technical services superinten-dent. This necessitated the move of store QA Technicians from the-plant services department to the QA Group under Engineering Support Superviso The reorganization will provide effective communication and prompt exe-

.cution of plant directives and activitie .

.

The inspector also reviewed administrative procedure AP-0021, Maintenance Requests, and safety-related MRs 86-1303, 86-1359 and 86-1386.Section IV.2.g of this procedure states that the plant personnel who are assigned to perform the repair shall " document completion of QC hold points and any special inspections in the appropriate blank". Accordingly, the specific section for QA/QC hold point on the MRs was signed by an indivi-dual other than the-inspecting individuals assigned to witness the hold points and witness steps. However, the inspecting individual did issue his own inspection reports indicating witness of the hold points and the result thereof. The licensee agreed to review the aaequacy of procedure for lack of clarity for verification of witness and hold points remains unresolve (50-271/86-20-02).

4.0 Non-Licensed Staff Training 4.1 General The purpose of this portion of the inspection was to assess the effectiveness of the non-licensed training program implementation. As a representative sample, the inspectors chose the training programs for instrumentation and control (I&C)' technicians, electrical and mechanical maintenance personnel, Auxiliary Operators (AO) and Peer Inspector The A0 Training is the only non licensed staff tra1ning program that is INPO accredited. The licensee is committed and expects to have the other five non-licensed training programs INP0 accredited by December 31, 1986.

'

The effectiveness of the existing program was determined by reviewing the following to the requirements of the applicable procedures listed i Attachment Shift turnover for NP0 (0630,1530, 2315)

-

A0 activities on day shift (conducting nuclear roving rounds; and system and equipment verification).

Quality Assurance (QA) Audits and Surveillance Audits 4.2 Details of the Review For each of the job functions identified in paragraph 3.1, the inspector reviewed the established training program, implementing procedures, qualification, and experience of personnel, qualification and training of instructors, quality of on-the-job (0JT) or Job Performance Measure (JPM)

training,-and the effectiveness of training as evidenced in daily activitie The comments and evaluations from the trainees, line supervisors, and instructors were also reviewed to establish how this feedback was factored into future training. Management and Quality Assurance (QA) involvement in the training area'were assessed for effectivenes .3 Observation of Work Activities The ins'pector witnessed the work activities identified in Section above. The activities were conducted in accordance with the~ procedures by personnel knowledgeable in the requirements of the procedures and technical specifications. This was especially evident in the following:

During the nuclear rounds, the A0 noted that the Clean Up Differential Gage for.the.Demineralizer Pump was reading zero rather than 3.7 psi He immediately notified the control room and recorded the event in'the site log and his rounds log (VYAPF 0150.02, Rev 23).

MR 86-1879 required that the solenoid valve internals be replaced in accordance with ASCO Bulletin 8210. When the internals were removed it was noted that the diaphragm sealing area was " crushed". The new internals were installed and the valve assembly was to be torqued to 144115 in-lbs. in accordance with the Bulletin. When the torque value

,

reached 100 in-lbs, the I&C quality control (QC) inspector (peer l inspector) notified the I&C Supervisor and they agreed to torque to 129

in-lbs. With the lower limit value the valve did not' fail and the l licensee will be advising ASCO of the results.

!

Special training was conducted by the assistant foreman in accordance with the Limitorque letter for installing spring pack grease release j tubing, and OP 5220. Thi5 training was performed prior to conducting work in accordance with MR 86-123 Assurance of the need for peer inspections to be " independent" was demon-strated during the processing of the QC Inspection Report No.86-147 of MR 86-1781. The QC Inspection Report contained the signatures of three l individuals performing peer inspection. The first inspector had a minor I part in the job and supervision replaced him. The second inspector had l not completed his qualifications for peer inspector and was also replaced.

! The third inspector verified the previously inspected work prior to pro-l ceeding with the completion of the inspection.

4.4 Training Policy and Progress The inspector reviewed selected proce'dures, to understand the documented training program. The key procedures are the Training Program Management Plan (TPMP) and Administrative Procedure (AP) 0700 for Training Policy; AP 0715 for A0 Training, Department Procedure (DP) 0204 for Maintenance Training and DP0303 for I&C; these documents establish the bases for and the commitment to training, 0JT/JPM and measuring program effectivenes The training for A0's is conducted by two instructors at the new Training Center located in Brattleboro, Vermont. The inspector reviewed the lesson plans, student evaluations, and the instructor continued training. These were complete and processed in accordance with procedures. To obtain end of course or session evaluations, a program specialist meets with the students without the instructor being present. The specialist provides and discusses the results of the meeting with the instructor. In addition to this evaluation and periodic appraisals, unscheduled " class room observations" by peers are also conducted. Student critique sheets are evaluated and actions, if required, are taken in a timely manne Training for example, added a CDR Hydraulics course, and a Simulator -

Training for A0s course in' response to student critiques. They are also preparing a Heat Transfer and Fluid Flow course in response to student request All Licensee Event Reports (LERs) were reviewed and one (LER 86-04) will be incorporated in the next requalification session. To measure effectiveness, the instructors visit the plant at least once per wee These visits included review of training adequacy with supervision, review of recent hardware and procedure changes at the plant and discussions with student Th2 Maintenance Department training for foremen, assistant foremen, lead plant mechanics, assistant mechanics, utility men, and engineers is being revised for INPO accreditation. A training coordinator spends two days per week at the Training Center to assist the training experts in developing a training program for INP0 accreditation. The present training is in accordance with DP 0204. The procedures states that the training "will consist of a on-the-job training, on-site training by j vendor representatives, and off-site training at vendor schools. DP 0204 further states "All department personnel have exhibited proficiency in one or more trades prior to being hired." DP 0204 intends "to demonstrate that department personnel are trained in the application of their trade as it applies to the plant equipment." The inspector reviewed the implementation of the department training through MR 85-1977, MR 86-1236, and MR 86-178 The personnel involved in the work were journeyman prior to being hired and were qualified. They had spent 8-18 months as assistant plant mechanics learning the plant specific Upon completing the requirements

,

listed on form VYDPF 0204.02 of OP0204, they were given a written

'

examination. Upon passing the examination they were promoted to plant

mechanic. Continued training is provided on an as needed basis at vendor and/or.off-site schools". They'are also required to review annually subjects such as LERs, technical specification, safety manual, the emergency plans, and review of plant modifications as they apply to the Maintenance Departmen Like the Maintenance Department, the I&C Department is revising it's training program for INPO accredition. The I&C training coordinator is spending two days per week to develop a program for the department supervisor, foremen, engineering assistants, and the technicians. The present-training is in accordance with DP 0303. .The training includes a three week systems course for I&C personnel given at the Training Center by licensee personnel, as well as the regular 0JT, required reading, in-house lectures, and vendor training. Again like the Maintenance Department, all I&C personnel were hired with prior experience, trained on the plant specifics and promoted to technician Peer inspection was formally instituted in January 1986 by the issuance of AP 6.025. With the outage underway, the peer inspection was conducted by qualified contractor QC inspector personnel. After the outage, I&C Department continued to use a contractor QC inspector to perform peer inspections under the direction of the I&C Department Supervisor. Post Maintenance Department peer inspection was conducted by supervisory personnel until recently when-the inspector reviewed the peer inspection for MR 86-1781, (see paragraphs 4.3 and 4.5).

The inspector reviewed the training records of those personnel who conducted the activities identified in paragraph The records were complete, easily accessible, properly filed and in compliance with Regulatory Guide (RG) .5 Findings Peer inspection is not addressed in the General Employee Training (GET)

or in the new employee indoctrination course Senior personnel qualify as peer inspectors by reading AP 6025 and passing a test regarding'the contents of the AP. The inspector discussed the training question with supervisory personnel and two peer inspector They all agreed that additional training was required. Concerns discussed included: acceptance criteria, (e.g. how clean is clean); communications; and writing credible reports. This is an unresolved item pending the development and implementation of additional training. (50-271/86-20-03).

4.6 QA/QC Interface with Non Licensed Staff Training The inspector reviewed three audit reports conducted in 1984-86 that I involved training. The audits were thorough, and the files contained the

.

.

checklists and the audit responses. In one case, audit report VY-86-18 noted that the Engineering Support Department personnel had not received peer inspection training in accordance with AP 6025. The response was being prepared by the audited organization at the time of this inspectio The Operations Quality Group (0QG) was tasked by the Plant Manager to perform extensive surveillance audits during the periods of July 1 through October 22, 1985, and April 7-11, 1986. The results of the surveillances did not deal with any training problem No violations were identifie .0 Unresolved Items Unresolved Items are matters about which more information is required to ascertain whether they acceptable items or violations. Unresolved items are discussed in paragraphs 2, 3, and .0 Management Meetings Licensee management was informed of the scope and. purpose of the inspec-tion'at the entrance interview on August 25, 1986. The findings of the inspection were discussed with licensee representatives during the course

, of the inspection and presented to licensee management at the August 29, 1986 exit interview (see paragraph 1 for attendees).

At no time during the inspection was written material provided to the licensee by the inspectors. The licensee indicated that no proprietary information was involved within the scope of this inspection.
