Dear Mr. Nellis:

In answer to your inquiry of August 15, 1979, there are approximately-205 uranium' dioxide pellets in each Z.ircaloy fuel rod at TMI-2. The exact number for any individual rod may vary by plus or iginus a few pellets since the fabricated pellet length dimension is not a rigid specification. The 205 value is based on a uniform pellet length of 0.700 inches. Enclosed is a copy of Figure 4.2-2 from the TMI-2 Final l

Safety Analysis Report that shows the fuel rod design. The dirnensions for the various components were provided in our previous letter of

. July 20,1979.

I trust that the above information satisfies your inquiry. Please let me know if additional information is needed.

Sincerely,

(.N Frank Schroeder, Acting Director Division of Systems Safety
