FW: Peer Review of SE Input for Vermont Yankee Core Plate Bolt Analysis (ME6248)6 Pani, attached is my input to the SE for the areas that I reviewed

-specifically, the determination of theamount of preload loss and the adequacy of the proposed inspection plan. Ganesh peer reviewed for me, seeemail below.I'm not sure how you structured your SE, so feel free to move things around and cut and paste my sections asneeded. We probably should meet to discuss.

I'll be in the office tomorrow and Thursday.

Peer Review of SE Input for Vermont Yankee Core Plate Bolt Analysis (ME6248)Ganesh,As discussed yesterday, please peer review (technical only) my SE input for Vermont Yankee. Use TACME6248. Note that it is not a complete SE because Pani has the lead on the SE. He can integrate my inputsinto the structure of his SE.If you.can give me comments by the end of the week that would be fine.Pat, I copied you so if you have time to review your comments would also be appreciated.

Thanks,Jeff7
