Dear Mr. Stolz:
Your letter of November 16, 1976, transmitted the NRC summary Enclosure of our meeting in Bethesda on October 28, 1976, regarding Davis-Besse Nuclear Power Station Unit I separation criteria for wireways and conduit. You also reques:ed that we amend the FSAR to conform with resolutions scated in the summary, and respond by November 30.

2.
Addressed on page 8-22, section 8.3.1.2.21 of FSAR Rev. 23 3.
To be addressed by revised Figure 8-20D in FSAR Rev. 24.
Please note that in item 3a, our comitment was to "42 inches" rather than the listed "46 inches".
Also, in item 3b, our commitment was to provide the fire barrier

Revised Figure 8-21C of FSAR Rev. 23 addresses our commitment.
