Docket No. 50-302

Dear Sir:

Attached for the staff's review are three (3) copies of the hydrogen generation calculations for each battery room and the control room complex at our Crystal River Nuclear Gen-erating Plant.

This information is being submitted in accordance with Mr. Schwencer's letter of May 6, 1974, concerning the dis-tribution of supplementary detailed data.

If further clarification or discussion of the above informa-tion is desired, please do not hesitate to contact us.

Very truly yours, J.
