This regeneration of time history thermal hydraulic loads subsequent to the Electric Power Research Institute (EPRI) testing and the analyses to determine the impact on previous analyses has been completed.

As a result of this analysis, it has been determined that the follow-ing activities are necessary:
tensioning of anchor bolts reposition of a snubber clamp maintaining an increased loop seal temperature These activities will be completed prior to start-up from our currcnt refueling outage and will ensure the operability and structural integrity of the system for all applicable loadings and load combinations l
including all pertinent safety and relief valve discharge cases.
Should you have any questions pertaining to the above, please do not hesitate to contact myself or members of my staff.
Very truly yours, i
