l Region IV U.S. Nuclear Regulatory Commission LU W 611 Ryan Plaza Drive, Suite 1000 Arlington, Texas 76012 RE: Reportable Occurrence: Non-Compliance with NSCR Technical Specification Requirements in Conducting Confinement System Surveillance

Dear Mr. Johnson:

In accordance with the Nuclear Science Center (NSC) Technical Specification reporting requirements (section 6.6.2) for the reportable occurrence of 19 March 1984, I am submitting the final report dealing with this matter. You will note, as I dis-cussed in our telephone conversation of 22 March, that I did not include the pro-cedural non-compliance involving the Weekly Intrusion Checks in the report. This item is addressed in the NSC Security Plan and is scheduled and performed on a weekly basis in much the same manner as the Weekly Electronic Maintenance Checks.

It is the determination of the NSC staff that this does not constitute a reportable occurrence as the NSC provides physical protection of SNM in accordance with 10 CFR 73.67(f).

Sincerely,

/ 602fd Barry Willits, Manager Reactor Operations BW/ym i

1 Reportable Occurrence Non-Compliance With NSCR Technical Specification Requirements in Conducting Confinement System Surveillance i Reportable Occurrence On 19 March 1984 during preparations to conduct the Weekly Electronic Maintenance Checks (NSC Form 316) it was discovered that the performance of this surveillance was not accomplished during the previous week of operation. The performance of this check includes the weekly surveillance of the Nuclear Science Center Reactor (NSCR) confinement system ventilation. This surveillance is addressed in section i 4.4 of the NSC Technical Specifica^tions. The objective is to assure proper operation

! of the equipment necessary to achieve confinement. The surveillance is specified as being performed on a weekly basis and basically involves a check of the various automatic and manual modes of ventilation system shutdown, such that any release

+

of radioactive airborne contamination would be controlled.

The timely completion of this surveillance is the responsibility of the Reactor Supervisor (normally day shift). The surveillance is routinely performed by the Reactor Operations support personnel of the electronics maintenance shop. During the operation week of 12 through 16 March 1984, this check was not performed, despite the fact that the NSCR was operated and normal business was conducted on just two

days (12 through 13 March). This surveillance was performed satisfactorily during i the previous week on 9 March, and again performed satisfactorily on 20 March, once j it was verified that the check had not been performed the previous week.

The NSC staff and management has determined that the failure to perform this sur-3 '

veillance does not constitute a safety question-or directly violate a limiting condition for operation. The report of this non-compliance with Technical Specifi-

?

cations is being submitted as it involves an inadequacy in procedural controls j that could conceivably have developed into an unsafe condition. This report is

, submitted as specified in section 6.6.2 of the NSC Technical Specifications involving a reportable occurrence, as were the initial mailgram and telephone report, to the USNRC Region IV.

I Corrective Action The completion of a satisfactory surveillance check following the week of r;on-compliance is considered adequate by the NSC staff as initial correctlye action.

As a long term solution, the staff of the NSC feel that the performance of this surveillance should be made more visible as far as completion or non-completion 4 is concerned. A maintenance and surveillance master schedule or planning sheet

_ is to be developed and placed in a location where a review can be readily accom-4 plished by the Reactor Supervisor and Manager of Reactor Operations. Until such a schedule is developed and as a temporary measure, the Manager of Reactor Operations will review and sign the weekly check sheet upon completion by the assigned personnel.
