Dear Sir:

On September 10, 1985, the NRC transmitted the results of the Staff's audit of the i

1 - SPDS Design Basis 2 - SPDS Critical Safety Function Selection 3 - SPDS Status Trees Development 4 - SPDS Logic Generation 5 - SPDS Logic Verification 6 - SPDS Human Factors Program 7 - SPDS Software Verification and Validation 8 - SPDS Maintenance Very truly yours,
