RE: Changed the Fatigue monitoring Write-up Except for the minor point: the inspector could not have reviewed the usage of the FatiguePro program ... they ate not using it.

Changed the Fatigue monitoring Write-up Importance: High Is this OK and accurate ??

3.19 Fati-que Monitoring Program

a. Scope of Inspection Proposed SER Appendix-A Item 44, Metal Fatigue of Reactor Coolant Pressure Boundary, stated, in part:

The program will be enhanced to use the EPRI-licensed FatiguePro cycle counting and fatigue usage factor tracking computer program.

The inspectors reviewed Exelon's -IPROPOSSE-D usage of the FatiguePro software program, reviewed the list of high cumulative usage factor components, and interviewed the fatigue program manager.

b. Observations The inspectors noted that the FatiguePro program, although in place and ready-to-go, had not been implemented. Exelon stated the FatiguePro program will be implemented after final industry resolution of a concern regarding a mathematical summation technique used in FatiguePro.
