Docket Nos. 50-327 Tennessee Valley Authority
)
50-328 In accordance with our commitment to Regulatory Guide 1.68.2 and Regulatory Positions C.2.a and C.2.b of Regulatory Guide 1.108, as documented in response to question 17.78 in the Sequoyah Nuclear Plant (SNP) Final Safety Analysis Report (FSAR), enclosed are revi-siens to FSAR Tables 14.1-1 and 14.1-2.
These revisions to the diesel generator preoperational and startup tests will be incor-parated into the SNP FSAR by Amendment 62.
The requirements of Regulatory Guide 1.108 not covered in the preoperational and startup test programs are met by the surveillance requirements of technical specification 4.8.1.1.
Very truly yours, TENNESSEE VALLEY AUTHORITY
