Dear Mr. Denton:

During the NRC staff's review of the Shearon Harris Nuclear Power Plant Technical Specifications, a Plant System Branch reviewer requested that the FSAR description of the hydrogen recombiners be expanded to include a discussion of the automatic controls that prevent oxygen concentrations from reaching the flammability limits. Marked-up pages of the FSAR are attached and willbe formally incorporated into the FSAR in a future amendment.

If you have any questions, please contact Mr. Gregg A. Sinders at (919) 836-8168.

Yours very truly, GAS/pgp (3910GAS)
