DAVIS BESSE POWER UPRATE (IP 71004) INSPECTION DOCUMENT REQUEST Importance: High
- Tej, The following information (paper copy if practicable, unless otherwise indicated) is requested to be available in Region III on January 19, 2009. If you have any questions regarding this information, please call J. Bozga (630-829-9613) as soon as possible.
- 1. Engineering evaluations performed to determine the impact of the measurement uncertainty power uprate on HELB.
- 2. Changes to controls, displays, and alarms including:
Setpoint changes made in the Reactor Protection System (RPS) for establishing trip parameters to ensure that safety margins are maintained during normal and transient plant operations.
Changes to the plant computer software for the Incore Monitoring Detector System.
Revisions to SPDS to display the trending performance of the Caldon LEFM system parameters.
Annunciator alarm(s) and procedure changes added to alert the operators when the Caldon LEFM system has self-diagnosed a condition that has resulted in an internal alert or failure.
- 3. All changes to the operator training program resulting from the measurement uncertainty power uprate.
- 4. Setpoint calculation changes made for, or resulting from, the measurement uncertainty power uprate.
- 5. Preventive maintenance program changes due to the measurement uncertainty power uprate, especially in regards to the LEFM.
- 6. Any information demonstrating that the LEFM system measures the FW flow and temperature consistently with the [existing FW] venturies and [resistance temperature detectors]
RTDs.
- 7. Operator training specific to the LEFM and analyses used to develop the training.
- 8. A list of any EOP and/or AOP changes (include any other procedure changes due to the measurement uncertainty power uprate also).
- 9. List any changes to the plant simulator and have the verification/validation available for review.
- 10. List all corrective action documents associated with the measurement uncertainty power uprate especially in regards to transducer failures.
- 11. Safety Evaluations (50.59 evaluations and screenings) performed to determine the impact of measurement uncertainty power uprate on systems, structures or components.
- 12. An electronic copy of Davis Besse UFSAR.
- Thanks, John V. Bozga
