SUMMARY

RELATED TO AMENDMENT REQUEST REGARDING INSTALLATION OF THE UPPER CONTAINMENT POOL GATE IN MODES 1, 2, OR 3 AND THE DRAIN-DOWN OF THE UPPER CONTAINMENT POOL DURING MODE 3 (CAC NO. MF7476) (L-16-083)

Dear Mr. Hamilton:

By letter to the U.S. Nuclear Regulatory Commission (NRC) dated March 15, 2016, FirstEnergy Nuclear Operating Company (FENOC) submitted a license amendment request that proposed changes to the technical specifications to permit the installation of the upper containment pool gate in MODES 1, 2, or 3, and the drain-down of the reactor well portion of the upper containment pool during MODE 3, for the Perry Nuclear Power Plant, Unit No. 1.

To enhance the NRC review of the request, the staff conducted an audit of supporting documents during the week of September 6, 2016. The staff reviewed the documents and held discussions with members of FENOC and its contractor, Zachry Group. The regulatory audit summary is enclosed.

While the NRC review team did not identify any significant issues during its audit or during the discussions with FENOC and its contractor, the team indicated that the review was ongoing and that any additional information necessary to support the review would be formally requested.

D. Hamilton If you have any questions, please contact me at (301) 415-1627.

Sincerely, Kimberly J. Green, Senior Project Manager Plant Licensing Branch 111-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-440
