PIPESTRESS - Integrated validation tool


An unusual feature of PIPESTRESS is that the validation tool implemented in PepS, permits the user to run a large subset of DST’s QA Verification Test Set of problems and compare the solutions with DST’s QA solutions. A comparison log is generated which indicates any unequal compares in the solutions which can then be investigated by the user.

Approximately 150 VTS problems are included in the validation tool which include the 14 NRC benchmark problems:
NUREG/CR-1677 Vol I (1980);
NUREG/CR-1677 Vol. II (1985); and
NUREG/CR6414 (1997).

The full validation tool procedure takes less than 30 minutes and thus can be performed regularly when modifications are made to the user’s computer configuration.
