Gentlemen:
In our effort to respond to the requirements of Reference (a),
Baltimore Gas and Electric, Northeast Utilities and the Omaha Public Power District' hereby sutnits ten (10) copies of Revision 1 to Appendix E of the Corbustion Engineering Owners Group Final Report submitted in Reference (b).
One of these copies is being forwarded directly to your Mr. Steve Hosford for reviev.
The revised Appendix E presents a detailed description of the analysis used to demonstrate acceptable ECCS performance with reduced area
- coolant channels in the peripheral fuel assemblies. The results of this analysis show that the. current licensing audysis pertaining to the hottest
. fuel rod in the core is more limiting than that for the hottest rod in a
' peripheral l assembly with reduced area coolant channels.
We' believe that on the basis of these results and the results submitted in ' Reference (b) that continued operation of Calvert Cliffs Units 11and.2, Fort Calhoun and Millstone Unit 2 is justified.
Very truly yours, i
