SUBJECT:
SAFETY ANALYSIS REPORT - AMENDMENT APPLICATION TO AUTHORIZE FAN SHUT 0FF, SEPTEMBER 21,1978, AS MODIFIED DECEMBER 12 AND 22,1978, PC N0. 79028A, MC REVIEWER:
Robert L. Stevenson
Background
By letter dated September 21, 1978, UNC requested approval of a
=
change in the health physics procedures (Section 400 of the license conditions for SNM-777) to allow planned shutdown of ventilation equipment. The superseding application of December 12 provided additional information to show that there would be no backflow of air through the system under the proposed shutdown conditions, m
information requested in a telecon to UNC on November 27. The transmittal of December 22, 1978, was necessitated by a typographical L
omission in the information sent December 12.
Discussion m
The UNC amendment application concerns the planned shutdown of ventilation equipment for such operations as repairs or maintenance, and hence concerns the control of radioactive contamination and exposure of plant personnel to airborne material. The application of September 21, 1978, indicated that airborne radioactivity levels would be monitored but it was not clear how possible backflow would be prevented. The revised (December 12) superseding application states that flow reversal will be prevented by positive action such as capping the stack or other appropriate means.

- During a discussion of the proposed amendment as revised December 12 with the principal I&E inspector for the Wood River Junction Plant (Mr. J. Roth of Region I), it was noted that paragraph 2.4 of Section 404 had been omitted. Mr. Roth noted that the missing paragraph had included significant requirements applicable to the operation, but otherwise had no objection to the proposed amer dment as revised. The omission was corrected in the December 22, 1978, application.
Conclusion and Recommendation Based on the facts summarized above, the proposed procedure for ventilation shutdown could be enaugurated without undue risk to the health and safety of the operating personnel or to the public.
Further, the procedure authorized by this license amendment would not result in a significant effect to the environment.
Approval of the authorizing amendment is recommended.
