The review by CSB of the Unit 2 containment purge and vent system was completed ih October 1978 (Reference 2).
CSB concluded that Unit 2 (1)
- should be permitted to u'se the upper compartment purge system, lower compartment purge system, instrument room purge system, and containment pressure relief system, individually, but not concurrently, as frequently as needed dur ing all plant operating modes and (2) should be required to leak test the containment isolation valves for the above systems following each use of a system.
I Due to the fact that the Unit 1 purge and vent system has been confirmed to be identical with the Unit 2 system, the Plant Systems Branch, Section B, agrees with the licensee that the conclusions of the safety evaluation of Unit 2 are directly applicable to Unit 1.
The Safety Evaluation Report
-issued 'by CSB on the Unit 2 containment purge and vent system (Reference
- 2) should, therefore, be expanded to include the acceptability of -the
- Unit, 1 system.
The PSB, Section B review of the Unit 1 system acceptability did not address the electrical aspects of the containment purge system at the D.C. Cook Nuclear Plant, nor did it address concerns that other branches
~ involved in this generic issue (e.g.,
EB/DOR, EEB/DOR) might have.
We, therefore, do. not'lan to conduct any non-elected review of this matter.
Please advise me if you are not in agreement with this approach.
