SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos.1 & 2; Docket Nos. 50-317 & 50-318 Request for Additional Information Regarding Baltimore Gas and Electric Company Toxic Gases Calculations for Control Room Habitability

REFERENCE:

(a)

Telephone Conference between Mr. G. E. Gryczkowski, et al. (BGE) and Mr. A. W. Dromerick, et al. (NRC), dated July 13,1999, same subject Attached is information we agreed to provide you in Reference (a). As discussed during the telephone conference, the attached calculations are the bounding cases for toxic gases. We will make a final submittal for toxic gases after you have completed your review of ARCON96.

Should you have questions regarding this matter, we will be pleased to discuss them with you.

Very truly yours, jy y
