SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos. 1 & 2; Docket Nos. 50-317 & 50-318 Emergency Response Data System The attached revision to the Emergency Response Data System (ERDS) Data Point Library for the Calvert Cliffs Nuclear Power Plant is provided pursuant to 10 CFR Part 50, Appendix E, Section VI.3.a.

The table below provides a brief summary of the changes:

Previous Sensor New Sensor Point Identifier Unit Description Range Range X2433 I Wind Speed 0-100 mph 0-50 m/s X2367 I Wind Direction 0-1080 deg. 0-540 deg.

X2433 2 Wind Speed 0-100 mph 0-50 m/s X2367 2 Wind Direction 0-1080 deg. 0-540 deg.

The "before" and "after" ERDS Data Point Library sheets are attached.

Should you have questions regarding this matter, please contact Mr. Jay S. Gaines at (410) 495-5219.
