• Mr. Edson G. Case, Acting Director Serial No. 045A/020177 Nuclear Reactor Regulation PO&M/RWC:das U. S. Nuclear Regulatory Commission Docket Nos. 50-280 Washington, .D. C. 20555 50-281 License Nqs. DPR-32 DPR-37 Attn: Mr. Albert Schwencer, Chief Operating Reactor Branch 1

Dear Mr. Case:

This is a status report on the auxiliary building ventilation system modifi-cations. The preliminary design is complete and follows the framework presented in our May 9,' 1977 letter (re:sponse to questions .1114 and. //16).

The exhaust from all ECCS equipment areas is reduced to within the capacity of a single filter train while the second.train is reserved as standby. A new nonsafety related filter train is provided to allow continuous filtration of ex-haust from most of the auxiliary building cubicles.

The final design work has begun and construction is scheduled to commence early in 1979. We will continue to keep you informed of our progress in this matter.
