Licensee Action on Previous Irspection Findings (Closed) Infraction (317/78-22-03, 318/78-16-03): The inspector verified that a training session was held on August 14, 1978, during which Rad-Chem technicians were re-instructed in the use of procedure RCP-2-402.

Special emphasis was placed on the use of rejection stickers and the prevention of use of instrumentation that is out-of-calibration.

In addition, instruments which have been rejected are now segregated and not accessible for use.

(Closed) Infraction (317/78-22-04, 318/78-16-04): The licensee has prepared procedure RCP-3-605 " Supply and Utilization of Quality Breathing Air," Revision 0, November 16, 1978, which provides for the control and maintenance of respirable air.

(Closed) Infraction (318/78-19-03): Disciplinary action was taken with personnel involved in the event where the SIT was at a level greater than allowed by T.S. and a letter reviewing this event and reminding them of their responsibilities in operating the facility in strict compliance with Technical Specification requirements was sent to all Shift Supervisors and Senior Control Room Operators (See Details, Paragraph 3).

.

.

.

(Closed) Infraction (318/78-20-01): This item describes the failure by the licensee to obtain grab samples of the containment atmosphere while the containment particulate radioactivity monitoring system was out of service. The licensee issued a letter to all Control Room Operators with copies routed to Shift Supervisors and Senior Control Room Operators emphasizing the responsibilities of all licensed operators to be aware of Limiting Conditions for Operation and verifying compliance with action statements of the Technical Specifications (See also Details, Paragraph 3).

3.

Failure to Comoly with Technical Specifications During a routine reactor trip recovery, the reactor was made critical with Technical Specification action statements 3.7.3.1 and 3.7.5.1 in effect. The No. 11 component cooling system and the No.11 saltwater sub-system were inoperable.

The operators' actions taken in this event are in violation of Technical Specification 3.0.4 Limiting Condition for Operation.

Similar events involving the operation of the facility in violation of Technical Specification requirements have been cited previously in NRC inspections 50-317/

78-26; 50-318/78-20; and 50-317/78-25; and, 50-318/78-19 conducted on September 5-8, 1978, and September 12-15, 1978, respectively.

This item of noncompliance is categorized as an Infraction (78-38-09).

c.

During the review of Maintenance Requests (MR) it was determined that certain M. R.'s:1) did not include or reference instructions for equipment return to normal operating status, and/or 2) did not contain documentation of equipment functional acceptability for the operations departmen.

'

.

.

The following M. R. 's did not contain documentation of functional acceptability, 'and no record substantiating the completion of the operability test could be located: M. R. 0-78-765 (Maintenance Foreman's instructions required a one hour trial run prior to return of equipment to service), and M. R. M-78-2128 (did not include or reference instructions for equipment return to normal operating status).

The following M. R.'s did not include or reference instructions for returning equipment to normal operating status, and did not contain documentation of equipment functional acceptability.

However, test acceptability was substantiated through review of completed surveillance tests: 0-78-3217, 0-78-3218, M-77-2295, M-77-2296, M-77-2297, M-78-4058, 0-78-620, and M-78-4058.

The following M. R.'s did not include or reference instructions for equipment return to normal operating status; however, functional acceptability was documented as required: 0-78-2132, 0-78-2349, and M-78-188.

The above conditions represent an apparent noncompliance (deficiency) with T.S. 6.8.1; ANSI N18.7-1972, section 5.3.5; CCI-200B, August 1977 (317/78-38-01 and 318/78-34-01).

During discussions, the licensee stated that the above problem was considered documentary in nature, and that post maintenance testing was accomplished concerning the M. R. 's in question.

Based on conversations with Maintenance and Operations personnel, the inspector noted that there appears to exist, in some cases, a difference of opinion between the two departments as to whether a post maintenance test is required, and if so, the type of test required depending on the kind of maintenance performed.

The licensee acknowledged the inspector's comment.

d.

Associated with the review of M. R.'s, reference was made to various logs in an effort to verify that post maintenance testing was accomplished satisfactorily. Through this process it was determined that the Unit 1 control room log, dated May 11, 1978 through November 6, 1978, could not be located.

This item is unresolved pending completion of actions by the licensee to locate the 109. book and subsequent NRC:RI review (317/78-34-02).

.

.

7.

Administrative Controls for Calibration Administrative controls were reviewed to determine the licensee's program for implementing requirements associated with the control of safety related calibrations, as specified in Technical Specifi-cations, Section 6, Regulatory Guide 1.33, Quality Assurance Require-ments; and, ANSI N18.7, Administrative Control for Nuclear Power Plants.

During the review it was determined that the Preventive Main-tenance (PM's) Card and Functional Test Instructions (FTI's)

constitute the procedure for control of the calibrations of these type instruments. However, these two documents collectively lack certain procedural aspects for the calibration of in-line instruments / gauges.

Specifically, the PM card and the FTI do not provide for on-shift operations personnel formal release of the equipment for preventive maintenance and for the documen-tation of functional acceptability by the on-shift operational personnel.

In some instances, it was noted that a maintenance request (MR) number (which does provide for the operation department interface as discussed above) was documented on the calibration data sheet or the MR was attached to th data sheet. However, this was done primarily in cases for corrective maintenance and not for routine calibrations.

The licensee representative acknowledged the above and stated that this issue had been addressed previously and it appeared to be resolved through.the use of PM weekly schedules.

However, the inspector stated that these schedules do not appear to schedule PM's on a shift basis.

It was noted that administrative

.

controls for the PM system require the permission'of the shift supervisor prior to the performance of a PM but these controls do not provide for documentation of this release of equipment.

The licensee representative stated that this area warranted further review. This is unresolved pending review by the licensee and subsequent NRC:RI inspection in this area (317/78-38-03 and 318/78-34-02),

d.

It was determined that certain instruments could not be cali-brated due to physical restrictions.

Specifically, for Pressurizer Temperature, tap-in points for the loop calibra-tions are physically inaccessible.

This is being reviewed to determine the feasibility of establishing a support structure in the area or to use other instrumentation, that is accessible for calibration, to comply with the TS limit on Pressurizer Temperature heatup rate and Spray Line Differ-ential Temperatur.

.

.

Also, the pressure gages for the Cable Spreading Room Halon System are unisolable from the respective storage bottles.

The licensee representative stated that this system is under review by the Office of Nuclear Reactor Regulation (NRR)

and that modifications may be warranted in which consideration will be given to isolable pressure gages.

In the interim, the Fire Inspector has been notified to provide bottle fittings with isolable pressure gages when these bottles are sent off site for recharging through vendor services.

This area is unresolved pending the calibrations of instruments used to comply with the Limiting Conditions of Operations in TS for the Halon System Pressure and Pressurizer Temperature, and subsequent NRC:RI review (317/78-38-04 and 318/78-34-03).

e.

The suction gages (not ambered) for the Boric Acid Pumps do not have corresponding PM cards for periodic calibrations.

However, these gages are temporary and have been calibrated in tie past on a periodic basis.

The licensee representative stated that all gages associated with Inservice Inspection (ISI) Surveillance Procedures are being reviewed under a Facility Change Request and that a result of this review will be to assure PM's exist for periodic calibrations of these gages.

This is unresolved pending the incorporation of all ISI gages into the PM system and subsequent review by NRC:RI (317/78-38-05 and 318/78-34-04).

f.

During the review of calibration data it was noted that several records for these calibrations were stamped with 1 year retention periods. This was observed for calibration records gages /!r.stru-ments in the Fire Protection System and Boric Acid System.

The Technical Specifications, Section 6, requires a 5 year retention for such records.

The licensee representative acknowledged the above and stated that the present Quality Assurance System for maintaining plant records is keeping all documents on a permanent basis.

It was indicated that this may not be true in the future.

The inspector did not notice any instance of missing calibration records since the establishment of this calibration program.

The inspector stated this area will be reviewed in a subsequent inspection (317/78-38-06 and 318/78-34-05).

Performance of Calibration / Functional Tests The inspector witnessed the performance of Unit 1, M-210-B-2, Revision 7. September 6,1978, Reactor Protection System Functional Test,Section II (Power Range) on December 14, 1978.

This was to verify performance consistent with approved procedure and to verify the implementation aspects for the control of test equipment.

No items of noncompliance were identified.

12. Technician Qualification The inspector reviewed the qualification records of selected personnel having responsibility for calibration and maintenance of safety related systems and components to verify that the individuals experience level and training were in accordance with ANSI N18.1, Selection and Training of Nuclear Power Plant Personnel, Section 4.

During this review, it was determined that one individual assigned to the Instrument and Control (I&C) Group (employed by the licensee August, 1978) lacks the required 2 years working experience in the I&C specialty. This person was qualified by the licensee to per-form certain Technical Specification Surveillance Procedures at a Level I capability in accordance with ANSI 4.5.2.6, Draft 3, October,1974, Qualification of Inspection, Examination, and Testing Personnel for the Construction Phase of Nuclear Power Plants.

ANSI 4.5.2.6 provides for optional experience requirements other than the 2 years working experience.

Based on a review of the individual's background records, it appeared to the inspector that the Level I requirements of ANSI 4.5.2.6 were met for this employee.

However, the inspector emphasized that Technical Specifications reference ANSI 18.1-1971 for the qualifications of onsite organization personnel and the Operational Quality Assurance Program (FSAR Section 1.c) commits to both ANSI Standards.

Further, ANSI 4.5.2.6 sddresses primarily the quality assurance experience levels for quality assurance personnel and it is, therefore, inappropriate to use ANSI 4.5.2.6 to qualify onsite organization personnel not in the quality assurance area. This position is consistent with previous guidance from NRR on the same issue.

Based on a review of selected records of calibratic safety e

related instruments and on discussions with licenses asentatives, it appeared the subject individual has not performed 1 ourveillance Procedures above, even those for which the person is qualified as documented on Certificate of Qualificatio.

.

-

.

The licensee representative acknowledged the above and stated that this area will be reviewed.

It was also stated that until resolution of this issue, the subject individual will not be permitted to per-form any TS Surveillance Procedures or other safety related functions in other than a training capacity.

Further, it was stated that upon completion of the above review appropriate programmatic changes will be made.

This is unresolved pending completion of action by the licensee as stated above and subsequent NRC:RI review (317/78-38-07 and 318/78-34-06).

13.

Personnel Identification and Dosimetry On December 13, 1978, during discussions with personnel, the inspector observed that one individual (A) was wearing another individual's (B) identification badge.

Both individuals are members of the onsite organization with the same protected and vital area access eligibility.

However, along with the badge, individual A was wearing individual B's personnel dosimetry (Thermoluminescent Dosimeter - TLD).

The wrong badge /TLD had been issued approximately 7:00 a.m. that day and individual A returned to the guard house at approximately 11:00 a.m.

for the proper badge /TLD.

Subsequently, the licensee conducted an analysis of the event with the following conclusions.

No other employees were involved in the mix-up.

Individual B

--

had not reported to the site that day; but had he reported, the error probably would have been caught.

Individual A had not gone into any radiation areas and, therefore,

--

there would be no reason to suspect erroneous dosimetry readings on either individual A's or B's TLD.

The cause appears to be an error on the part of the guard who

--

issued the wrong badge.

Both badges were in close proximity to each other in the file rack.

The licensee representative stated that security procedures are being revised in this area to preclude recurrence of this event.

However, no definite plan could be presented to the inspector at the time of the inspection since review by both the onsite organiz-ation and security organization is warranted.

This is unresolved pending completion of action by the licensee as stated above and subsequent NRC:RI review (317/78-38-08 and 318/78-34-07).
