Subject:

Crystal River Unit 3 Docket No. 50-302 Operating License No. DPR-72 NUREG-0737, Item III.D.l.1 Integrity of Systems Outside Containment Containing Radioactive Material

Dear Mr. Stolz:

In partial response to the subject item, Florida Power Corporation (FPC) committed to install an auxiliary building cubicle door and ventilation louver (letter dated December 15, 1980). The installation of the door and louver was completed in October,1981, and February,1982, respectively. The delay in installation was due to field construction problems and manufacturer's delivery date of redesigned equipment.

An analysis of the effectiveness of the auxiliary building cubicle door and louver was requested of Gilbert Associates, Inc., on March 1,1982. gal's review of the previous ~

study, received March 23,1982, indicates that the door opening was the only penetration Oh G10 G204070252 820331 PDR ADOCK 05000302 p

A Mr. John F. Stolz March 31,1982 Page 2 considered and that proper operation of the installed louver will require the sealing of all compartment piping and electrical penetrations.

FPC is currently reviewing gal's recommendations and will ' complete any actions determined necessary by this review prior to December 31,1982.

If you have any questions regarding this item, please contact this office.
