Subject:
Byron Generating Station Units 1 and 2 Braidwood Generating Station Units 1 and 2 Emergency Operating Procedures WC Docket Nos. 50-454/455 and 50-456/457 References (a): December 14, 1983 letter from T. R.
Tramm to H. R. Denton.
(b): January 5, 1984 letter from T. R. Tramm Tramm to H. R. Denton.
(c): September 24, 1984 letter from T. R.
Tramm to H. R. Denton.
Dear Mr. Denton:
This letter provides the Procedures Generation Packages (PGP), one each for Byron and Braidwood, which are being used to upgrade each station's emergency operating procedures. These procedure changes are being made to satisfy the requirements of NUREG-0737, Supplement 1, regarding Revision 1 of the Westinghouse Owners Group (WOG) Emergency Procedure Guidelines (EPG's).
As indicated in references (a) and (b), the present Byron emergency operating procedures (EOP's) are based upon the Rev-Basic EPG's. In reference (c) we indicated that our PGP's for the Revision 1 EPG's would be provided within 3 months of the W C's approval. We understand that Revision 1 was approved on December 27, 1984.
The enclosed Byron PGP contains all the guidance used to draft Byron 1 E0P's. This drafting process is complete and the upgraded E0P's are in the review process. The upgraded E0P's will be implemented by December 27, 1985. The initial Byron 2 E0P's will be identical to the upgraded Byron 1 E0P's, except for minor changes necessary to correctly reflect the Byron 2 component identification and equipment configuration.

H. R. Denton March 26, 1985 The enclosed Braidwood PGP is nearly identical to the Byron PGP.
The differences are described in the attachment to this letter. As with Byron, the Braidwood PGP contains all of the guidance used to draft the Braidwood 1 E0P's. Most of the E0P's have been drafted and are in review.
The drafting process will be completed in a few weeks. The revisions will be implemented by Unit 1 fuel load. Braidwood Unit 2 E0P's will be identical to the completed Braidwood Unit 1 E0P's except, as at Byron, for minor changes necessary to reflect Braidwood Unit 2 component identification and equipment configuration.
Close coordination has been maintained between Byron and Braidwood to ensure that the Braidwood E0P's are as nearly identical to Byron's as the station configuration permits. Byron's E0P's were actually used as a first draft from which Braidwood's E0P's grew. This similarity makes it possible to reduce the effort involved in validation and verification of the upgraded E0P's. We intend to take advantage of this close coupling by allowing Braidwood to take credit for Byron procedure validations.
In a similar fashion, Byron will take credit for Braidwood's verification of its E0P's.
The basis for concluding that the E0P's are sufficiently similar will be established by a documented comparison study.
Please address further questions regarding this matter to this One signed original and fifteen copies of this letter and the enclosures are provided for WC review.
