Surveillance Testing and Calibration Control Program The inspector reviewed documentation to ascertain whether the licensee had developed and effectively implemented programs for surveillance testing, calibration, and inspections required by section 4 of the plant Technical Specification (TS). The program for calibration of other safety-related
'
instrumentation, not covered by TS, was also examined for adequacy and effectiveness.
The inspector interviewed and held discussions with li-censee personnel and cognizant plant management to assess their knowledge and understanding of the program requirements, and to review responsi-bilities assigned to various departments and sections of the licensee's organizatio.
.
2.1 Program Review The inspector reviewed the licensee's management controls for Sur-veillance Test and Calibration (ST) program. The ST program is man-aged and controlled by a computer program called Surveillance Test And Records System (STARS).
This computte system is used to store and track instrument calibration and surveillance test information.
This information includes the last date that a ST was performed, the date of the next scheduled surveillance, whether the scheduled date has been met, and the base number of days between tests and calib-ration.
The inspector verified that access to the program is controlled by the surveillance test coordinator (STC), who alone possessed the program access code. The STC is responsible for entering data into the system.
The computer program has several features which minimize the possibility of introducing mistakes while entering data that would be carried into the next calibration period. Spot checks are also performed periodically by the I&C department as well as formal audits by Quality Assurance. These audits further ensure that cali-bration frequencies and other data are correct as stated on the com-puter program outputs.
The inspector also verified a change to the computer program which involved a proposed TS change and the associated calibration fre-quency change that would need to be reflected in the ST program.
The program was then initiated to calculate the next calibration date, the inspector verified that the new calculated dates were correct.
2.2 Findings Based on the above review, examination, and discussions with cogni-zant personnel, the inspector determined that:
1.
A master schedule for TS calibration and functional testing of instrumentation and systems was established; the schedule in-cluded frequency of each test / calibration and/or inspection, the responsibility for implementation, and the surveillance test /
calibration status of the item or system.
2.
The responsibility for maintaining and up-dating the schedule was established and assigned by procedure.
3.
The current master schedule reflected the TS requirements for such tests and/or calibration, and 4.
The responsibilities for review and evaluation of data, report-ing and controlling deficiencies, and ensuring the required surveillance test / calibration was satisfied had been established by procedure.
.
The inspector had no further questions in this area. No vio-lations were identified.
3.
Calibration of Safety-Related Components Not Covered by Technical Specification The inspector reviewed the program description and examined records to determine if calibration requirements had been established for components associated with safety-related systems and/or functions, but that were not specified in the TS and if a master schedule had been developed that included calibration frequency, responsibility for implementation, and the calibration status of each component.
The inspector determined that a calibration program had been established for such safety-related components. A master schedule had been developed to show the responsibility, frequency, and the status of calibration for each safety-related component not covered by the Technical Specification, as well as to ensure adequate records were maintained.
No violations were identified.
4.
Surveillance Procedure and Records The inspector reivewed procedures and records to verify that surveillance of safety-related systems and components was being conducted in accordance with approved procedures as required by TS; and also if these procedures were adequate to accomplish the safety intent of the TS requirement, thus
,
assuring operational safety of the plant.
The inspector selected at least two tests from each of the following areas to verify the adequacy of conformance to the above requirements.
The tests were randomly selected from the master schedule for surveillance tests.
Documents reviewed are listed in section 8 of this report.
Areas included were:
Reactivity Control and Power Distribution,
Emergency Core Cooling System,
Containment System,
Plant Electrical Power System, and
Intrumentation 4.1 Findings Based on the above review and examinations, the inspector determined that the procedures were adequate to direct and control surveillance testing.
Procedures included required prerequisites and preparations for test; acceptance criteria; instructions and steps to assure that the system or components were restored to an operating condition after the test; and responsibilities for review and approval for the test data.
Procedures appeared to meet the intent of the TS surveillance testing requirements.

The inspector also determined that the records maintained for these tests were adequate. They showed that the completed tests were reviewed for acceptability of results; met the testing frequency; and were in confor-mance with the TS requirements for the surveillance / tests.
No violations were identified.
5.
Quality Assurance Program for Measuring and Test Equipment The inspector reviewed the licensee's QA program to ascertain if the program adequately provided administrative controls over measuring and test equipment (M&TE); and if the controls provided were in conformance with regulatory requirements, commitments, and industry standards.
The program review consisted of verification of licensee's commitments in the Final Safety Analysis Report (FSAR) for conformance with regulatory requirements, and review of procedures for adequacy.
The inspector de-termined that the licensee's commitments in the FSAR were generally ade-quate to fulfill regulatory requirements.
The procedures contained criteria and responsibilities for calibration frequency, methods for plac-ing in or removing equipment from service, and the calibration status of the equipment.
The procedures also included methods of documenting calibration history of equipment, including:
Traceability to calibration source,
As-found and as-calibrated data, Identification of standards used,
Identification of calibration procedure used, and its traceability to a national standard,
Date of calibration, and
Name of person performing calibration.
The procedure also specified that M&TE equipment must have accuracy four times greater than the equipment which was being calibrated. A system, very similar to the master schedule used for TS calibration, was in use for controlling the calibration frequency and recall of equipment.
Re-quirements for the history of use, and controls to prevent inadvertent use of equipment beyond calibration frequency were also established. The procedure also required an investigation and evaluation of data recorded by the M&TE prior to scheduled calibration if the M&T Equipment was found to be out of calibration. The inspector also questioned the responsible
.
I&C supervisor to assess his knowledge and understanding of the program, and found him to be knowledgeable.
i No violations were identified.

Quality Assurance (QA) Department Involvement in Surveillance / Calibration Program The inspector examined documents, and held discussions with QA supervisors and cognizant personnel to assess the understanding of their responsibi-lities in this area, and their involvement in the implementation of this
program.
Based on the above discussions and the examination of QA records, the inspector determined that the plant QA department performed planned struc-tured program audits. Additionally, QA personnel perform surveillance inspections routinely. The surveillance inspections are not comprehen-sive, structured inspections, but are limited scope inspections covering individual items, activities or a small part of the program. These sur-veillance inspections are designed to verify the overall implementation of calibration and TS surveillance test program.
,
Based on the above examination and discussions, the inspector determined that Quality Assurance management and staff were aware of their respons-ibilities; the planned audits were comprehensive, and were well documen-ted.
'
No violations were identified.
7.
Management Meeting At the conclusion of the inspection, the inspector met with licensee
!
management (identified in paragraph I with a *), at which time the in-spectors summarized the purpose, scope, and the findings of the inspec-l tion. The licensee acknowledged the inspectors' findings.
At no time during this inspection, did inspectors provide written material to the licensee.
