Review Status:
Compl ete In response to Technical Assistance Request TACS 48377 (Task Interface Agrement TI A 82-16), regarding the evaluation of Tec hnical Specification 3.3.b.2 as it relates to' contairr.ent cooling system operability for the Kewaunee plant, the Contairnent Systems Branch has completed its review and furnishes the enclosed Safety Evaluation Report.
The need for this review resulted from a recommendation by a reactor inspector from Region l
111.
In the enclosed SER, we conclude that the current Technical Specification 3.3.b.2 is deficient in that it allows combinations of inoperable contain-ment heat removal eouipment that could result in accident conditions less conservative than specified in the facility's Updated f5AR.
We have also suggested a revised Technical Specification that would correct these de-ficiencies.
This completes our review as called for in TACS 48377.
