Inspector Observations The following are observations the NRC inspectors discussed with the licensee during the inspection and at the exit briefing on October 3, 1986. These observations are neither violations nor unresolved items.
These items were recommended for licensee consideration for program improvement, but they have no specific regulatory requirement.
The licensee stated these items would be reviewed.
a.
Chemistry / Radiochemistry Training Records - The backlog of themistry/ radiochemistry training records needs to be transmitted to the nuclear training dersrtment for permanent record storage (see paragraph 5).
b.
Documentation of Corporate Reviews - The licensee should document the performance of technical reviews performed by the radiological services section (see paragraph 6).
c.
Contractor Laboratory Analytical Results - The licensee should followup on contractor laboratory analytical results which are in disagreement with known isotopic concentrations (see paragraph 12).
3.
Chemistry / Radiochemistry Organization and Management Controls The NRC inspectors reviewed the licensee's corporate and WCGS organizations and staffing regarding chemistry / radiochemistry activities to determine adherence to commitments in Chapter 13 of the Final Safety Analysis Report (FSAR) and requirements in Section 6.2 of the Technical Specifications (TS).
The NRC inspectors verified that the organizational structures of the
,
j corporate radiological services nuclear chemistry section and the WCGS chemistry / radiochemistry section (C/RS) were as defined in the FSAR and TS l
and unchanged from previous NRC inspections.
The corporate and C/RS staff l
assignments, management controls, and position descriptions were reviewed i
for the assignment of responsibilities for the management and l
implementation of the corporate radiological services nuclear chemistry section and the WCGS chemistry / radiochemistry programs.
It was verified that the administrative control responsibilities specified by the WCGS procedures were being implemented.
l The NRC inspectors reviewed the staffing of the corporate radiological l
services nuclear cher..istry section and the WCGS C/RS and noted that the l
corporate nuclear chemistry section was fully staffed and the two staff members were the same as reported in previous NRC inspection reports.
Since the previous NRC inspection in October 1985, the WCGS C/RS had lost and replaced two chemistry technicians.
The corporate and WCGS C/RS organizational structures and staffing were determined to be in accordance with licensee commitments.

Chemistry / Radiochemistry Personnel Qualifications The NRC inspectors reviewed the qualifications of the corporate radiological services nuclear chemistry personnel and WCGS C/RS personnel to determine adherence to commitments in Chapter 13 of the FSAR and requirements in Section 6.3 of the TS.
The NRC inspectors reviewed the education and experience backgrounds of the present corporate nuclear chemistry personnel and verified that they met the required qualifications specified in the FSAR and position descriptions.
Based on the review of the WCGS C/RS staff resumes, It was determined that all the supervisor staff and 9 of 14 chemistry technician positions were filled with personnel who satisfied the ANSI /ANS 3.1-1978 qualifications.
The C/RS has 12 shift qualified technicians and two recently hired technicians who were presently in qualification training.
The NRC inspectors reviewed the six-shift rotation schedule and determined that each shift was composed of at least one ANSI and shift qualified person.
,
No violations or deviations were identified.
5.
Chemistry / Radiochemistry Training Program The NRC inspectors reviewed the licensee's chemistry / radiochemistry training program to determine adherence to commitments in Chapter 13.2 of the FSAR and the requirements in Section 6.4 of the TS.
The NRC inspectors discussed the training program for C/RS personnel with the chemistry training program coordinator.
The nuclear training department had recently expanded its staff and added a training instructor in chemistry who had formerly been a technician in the WCGS C/RS.
The NRC inspectors reviewed the training department organization, chemistry training staff qualifications, position assignments, classroom and laboratory facilities, implementing procedures, initial chemistry technician training program outline, and C/RS training schedule.
Lesson plan development was reviewed and it was determined that the identified lesson plans were approximately 85 percent complete overall with 30 percent of the lesson plans finished and available for teaching.
The NRC inspectors also reviewed the development of the on-the-job (0JT)
training / qualification cards and found them based on objectives as determined by tasks analyses and approximately 85 percent complete.
The chemistry training program coordinator indicated that the goal was to complete the identified course lessons plans and 0JT training /
qualification cards by the end of 1986.
The NRC inspectors reviewed selected nuclear training department procedures which had been completed and approved since the previous NRC inspection in October 1985.
The NRC inspectors also reviewed WCGS Procedure ADM-04-004, " Chemistry Group Training Program," Revision 7, September 19, 1986, and found it

It was noted that the licensee was in the process of preparing a self evaluation report describing the chemistry training program and objectives based on position task analyses to be submitted to the Institute of Nuclear Power Operations (INPO) as part of the INP0 training accreditation program.
The NRC inspectors reviewed the C/RS individual staff training records and 1985 and 1986 requalification cards and found that training was being completed and documented in accordance with procedure.
It was noted that there was still a backlog of training records which need to be transmitted to the nuclear training department to be incorporated into the C/RS individual training records and microfilmed for permanent QA records.
The NRC inspectors discussed this observation with the licensee during the inspection and at the exit briefing.
The licensee agreed to evaluate this observation and transmit the training records as soon as possible.
No violations or deviations were identified.
6.
Chemistry / Radiochemistry Program The NRC inspectors reviewed the licensee's chemistry / radiochemistry program to determine adherence to commitments in Chapters 5, 3, and 11 of the FSAR and in Section 3/4.4.7 of the TS.
The NRC inspectors' review of the chemistry / radiochemistry program found that the licensee had revised and approved administrative procedures, surveillance procedures, chemical control procedures, instrument calibration and quality control procedures, sampling procedures, and analytical procedures.
A review of selected procedures revised and written since the previous NRC inspection in October 1985, daily logs, and analytical data indicated that the C/RS had established sufficient programmatic procedures to meet the requirements of the FSAR and TS.
The NRC inspectors reviewed chemistry and radiochemistry logs and records of completed chemical and radiochemical analyses and completed surveillance test records since the previous NRC inspection in October 1985 and determined that the required analyses were being performed.
The review also included discussions of the recorded trends of the secondary water quality data and reactor coolant chemistry parameters with the C/RS personnel.
The NRC inspectors reviewed the effectiveness of the secondary water chemistry program to measure and prevent the introduction of chemical containments into the secondary water systems and found the licensee's limits were established according to the Electric Power Research Institute owner's group guidelines for pressurized water reactor secondary water chemistry.
Interviews were held with C/RS personnel and it was determined that the staff at all levels understood the importance and need for water chemistry control.
The occupational exposure (person-rem) to plant personnel was reviewed as it relates to water chemistry control and found no evidence of increased occupational exposure as a result of poor water chemistr.
-7-The NRC inspectors verified that the secondary chemistry laboratory instruments and the primary chemistry laboratory instruments had been calibrated in accordance with procedures and an instrument quality control program had been implemented.
The licensee had implemented an inter-laboratory crosscheck program with several other utilities as well as an internal laboratory analytical accuracy crosscheck program to verify performance of C/RS technicians on analytical procedures.
The NRC inspectors reviewed the 1986 results of the two crosscheck programs and found that they demonstrated a high quality analytical capability.
The NRC inspectors reviewed the semiannual chemistry reports for the periods July through December 1985 and January through June 1986 produced by the nuclear chemistry radiological services section.
The reports included analyses trends of important chemical parameters in both the secondary and primary water systems.
The graphs and narrative portions of the reports indicated where specific problem areas may be developing, when out-of-specification conditions existed, and corrective actions which were taken to reestablish normal chemical parameters.
The chemistry reports were complete and helpful in evaluating plant chemistry performance.
The NRC inspectors reviewed several corporate procedures used to describe and implement the radiological services section nuclear chemistry program.
It was noted that not all aspects of technical review of the WCGS chemistry program were being routinely performed and the reviews documented.
These reviews of chemistry specifications, chemistry analytical procedures, chemistry quality control program, chemistry personnel training, and chemistry department activities, if performed, were not readily available for review.
This observation was discussed with the licensee during the inspection and at the exit briefing.
The licensee agreed to evaluate this observation and provide better documentation of chemistry reviews performed by the radiological services section in the future.
No violations or deviations were identified.
7.
Quality Assurance Program The NRC inspectors reviewed the licensee's QA organization and audit / surveillance program regarding chemistry / radiochemistry activities to determine adherence to commitments in Chapter 17 of the FSAR and the requirements in Section 6.5.2.8 of the TS.
The NRC inspectors reviewed the QA department organization, selected QA audit and surveillance procedures, audit schedule for 1986, QA auditor qualifications, and audit and surveillance reports. Audit and surveillance reports generated from QA activities during the period from August 1985 through September 1986 in the areas of chemical / radiochemical control, indoctrination and training, chemistry instrument calibration, chemistry sampling and analyses, and chemistry technical specifications surveillance were reviewed for scope to ensure thoroughness of chemistry / radiochemistry program evaluation and timely follow-up of
