Containment Purging During Normal Plant Operations R. E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Nr. Crutchfield:
Your letter of October 23,'979 requested that Rochester Gas and Electric Corporation (RG&E) commit to an interim position on containment purging.
As a guideline, the Staff's interim position was enclosed.
Our letter of December 14, 1979 presented RG&E's com-mitments based on the Staff's guidelines.
Following Staff review of those commitments, we were requested to revise our commitments by members of the Staff.
Accordingly, the following commitments are provided using the paragraph numbering of the October 23, letter.
Whenever the containment integrity is required, emphasis will be placed on operating the containment in a passive mode as much as possible and on limiting all purging and venting times to as low as achievable.
To justify venting or purging, there must be an established need to improve working conditions to perform a safety related surveillance, safety related maintenance procedure, or inspections re-quired to facilitate design or installation of safety re-lated modifications.
(Examples of improving working con-ditions would include reducing temperature,
- humidity, and airborne activity sufficiently to permit efficient performance or to significantly reduce occupational radia-tion exposures.)
This commitment supersedes our prior 90 hour0.00104 days <br />0.025 hours <br />1.488095e-4 weeks <br />3.4245e-5 months <br /> per year purge limit.
It should be noted that considerable judgment may be required in some instances to balance the goal of main-taining purging to as low as achievable and the goal of maintaining occupation radiation exposures as low as reasonably achievable.
- Further, judgment, may be re-quired in evaluating the need for purge while at hot shut-R006030~q P

down while performing cleanup following an outage when such cleanup is rectuired for safe operation of the plant.
2a.
Commitment number 2.a. is not revised.
The mechanical stops which limit purge valve opening were installed in December 1979.
2b.
Commitment number 2.b. is not revised.
As discussed with your Staff, our commitment 2.b.
meets your interim posi-tion.
