During his review of the event report and licensee
followup actions, the inspector determined that the
licensee had not prepared an investigative report for
review by the Operations Committee. .This was not in
accordance with requirements of Procedure SACD3.6,
Operating Occurrences and Events, which is an implement-
ing procedure for Section 18.2 of the licensee Quality
Assurance Plan, Revision 6, to ensure that event
investigation and reporting is timely.
Failure to prepare and' review an investigative report
for event P-RO-81-23 is considered to be a noncompli-
ance with 10 CFR 50, Appendix B, Criterion V, as
described in the Appendix of the-letter forwarding this
report.
b.
P-R0-81-27
No. 11 Shic'_d Building Vent System Inoperable (Closed)
The inspector reviewed the event report and the cor-
rective actions as stated in the event report. During
the review the inspector noted that the licensee had
identified an event where a system was returned to
service without performing all the necessary sur-
veillance requirements.
At approximately 0301 on November 21, 1981 the No. 11
Shield Building Ventilation System (SBVS) was taken
out of service for charcoal filter replacement of the
Pre, Absolute, and Charcoal (PAC) filter. Prior to
placing the No. 11 SBVS ("A" train) out of service
the No. 12 ("B" train) was tested satisfactorily for
operability.
Work Request Authorization (WRA) No. E6602-ZS-Q and
Radiation Work Permit (RWP) No. S-731 documented the
authorization to perform the actual work to replace
the charcoal filter trays. After completing the
charcoal filter replacement SP-1073 (Shield Building
Ventilation System Functional Test) was performed and
No. 11 SBVS raturned to service.
The WRA specifically noted in the Explanation and
Special Instructions section to perform SP-1080 (No.
11 Shield Building Ventilation System Charcoal Filter
Iodine Removal Efficiency, DOP and Freon Test) after
replacing the filters on the No. 11 SBVS PAC filter.
The filters were replaced on~ 11/12/81 but SP-1080 was
not performed until 11/16/81. Technically the No. 11
SBVS was not operable until the SP-1080 was performed.
However, the surveillance was completed satisfactorily
