Letter from hir. D. G. hicDonald, Jr. (NRC) to hir. G. C. Creel (BG&E), dated June 18,1991, Deletion of Containment Vent System Technical Specification 3/4.6.1.8 Gentlemen:
Reference (a) reported the status of the containment vent paths for Calvert Cliffs Units 1 and 2. The status was acknowledged in Reference (b). This letter updates that status and confirms the telephone notification made to your staff on June 24,1991, that we had, on that date, completed installation of a containment high radiation isolation signal on the containment vent line (htOV-6900 and 6901) for Unit 1. With the completion of this work, we have satisfied the Technical Specification requirements for operability of this system.
The footnote associated with Technica' Specification 3.6.1.8 allows the deletion of the limiting condition of operation and its associsice surveillance requirement.
Now that work is complete on both Units, we will request a i administrative Technical Specification change to delete this page as part of a future submittal.
'Ihe containment vent valves will now isolate upon receipt of either a safety injection actaation signal or a high radiation signel. By completion of thi; modification, we have establishe( a containment vent path for Unit I which is in full compliance with Thfi Action Item II.E.4.2. This complete
- the required actions for both Units in conjunction with this issue.
