V&V ISSUES REGARDING DIGITAL UPGRADES TO EMERGENCY CONTROL ROOM AIR TREATMENT SYSTEM
- 1. The NRC staff does not have a copy of the Software Requirements Specification.
- 2. There is no Software Validation and Verification, only a validation test. It appears that no verification was done at all. This means there is no record if the system specification was compared to the software requirements, if those were compared to the code or the test requirements, or if the code was reviewed.
- 3. The Software Validation Test Procedure # 9405603 has not been verified. How does the staff know that everything was covered?
- 4. The Software Validation Test Procedure # 9405603 seems incomplete. Throughout the test there are requirements to see if xxx relay is energized, without any hint as to how to determine this. The staff could not run the test from this test procedure.
- 5. The completed Software Test Data Sheets have a pass, the testers name (not readable) and the date (10-29-02) written in on the first test of the first page. All other tests, 55 pages worth, have a vertical line on the page for results, tester and date. Is the staff to assume that all tests were done on the same day?
- 6. There was one Test Incident Report attached to the Software Test Data Sheets. There is no indication of corrective action.
- 7. The staff does not understand how the digital system works. There does not seem to be a theory of operations section. There is much discussion on various features, but not on how the system operates, such as a signal flow walk through.
- 8. The Installation, Operation & Maintenance Instruction Manual is for an Area Monitoring System Model 955A Ginna is using a model 956. Is the 955 manual applicable?
- 9. The block diagram on pages 4-24, 25, and 26 of the Installation, Operation &
Maintenance Instruction Manual seems incomplete, i.e., where does the control signal bus come from, and how do the sensor values get into the system?
