Catawba Nuclear Station, Unit 2 Docket No. 50-414
Dear Sir:
On September 10, 1985, the NRC transmitted the results of the Staff's audit of the i
Catawba Unit 2 Safety Parameter Display System (SPDS). Section 4.6 of the audit results requested that Duke submit the Verification and Validation (V&V) Summary Documents describing both the V&V process followed and the results. As noted in our November 27, 1985 response, the V&V summary documents were scheduled for
-completion on July 1, 1986. The following summary packages are attached:
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,
'[
