Let.ter,'J. H. Nordahl (SPC) to Director, Office of Enforcement (NRC), "Siemens f
' Power. Corporation-Nuclear.Divis' ion Responses to the Demand for Information,
' Notice of Nonconformance, and Unresolved items (Inspection. Report 199900081/97-01)," February 24,1998.
Ref.: K. Letter, J.. H. Nordahl (SPC) to.Mr. Samuel J. Collins (NRC), " Additional Inforrnation 2
- for;SPC Responses to Non-Coriformances 97-01-02 and 97-01-04," NRC:99:005, February 4,1999.:
i This. letter provides the status of the commitments made by Siemens Power Corporation (SPC) related to our computer code documentation upgrade program. The two commitments of '
interest are 24 and 25, which are listed in Reference 1 and are further discussed in Reference
- 2. These commitments involve the c'onduct of. validation and verification and the' development
~,of user, theory, and programmer's ' manuals for numerous computer codes.' I had previously provided similar statu's reportRto the NRC in August and November 1998.
x Since my'last report of November.1998,'SPC'has completed 11 additional tasks: five user's
- manuals, four the'ory manuals, a programmer's' manual, and one V&V activity. In addition, it was determined that existing documentation adequately fulfilled compliance requirements for
~
.15 tasks.L A' number of computer codes that have been relied on' by SPC in the past are being replaced by codes that already meet the requirements for V&V and for supporting manuals.
~
LThis replacementfeffort will eliminate the need for 17 tasks.
- The remaining work' to be a'ccomplished 'ncludes
- (1f V&V on 12 codes and the preparation of i
- five user's manuela (all scheduled for completion by;the end of 2001) and (2) the development i f 26 theory and programmes's manuals,'which will be available by the end of 2002.
o
' Because'the~ current effort involves work on several lengthy tasks, the completion rate will be
~
lrelatively low for the next several months. I plan to provide the next status report in six -
4 months; that'is,.in October 1999.-
