Additional Utility Support for NEDE-33766P, GEH Simplified Stability Solution (GS3)

As noted in Reference 1, GE-Hitachi Nuclear Energy Americas LLC (GEH) is transmitting two additional letters from utilities documenting support for the review of licensing topical report (LTR) NEDE-33766P, Revision 0, GEH Simplified Stability Solution (GS3) and documenting the intent to implement the GS3 solution when approved by the U.S. Nuclear Regulatory Commission.

Specifically, Southern Nuclear Operating Company (SNC) has indicated a desire to implement GS3 in concurrence with the Hatch 2 Reload 23 in the Spring of 2015, pending successful approval of GS3 by the NRC. This is similar to the request stated in the Exelon letter contained in Reference 1 regarding the implementation at the Clinton plant in Spring of 2015.

If you have any questions, please contact me.

Sincerely, James F. Harrison Vice President, Fuel Licensing Regulatory Affairs GE-Hitachi Nuclear Energy Americas LLC Project No. 710

Subject:

Fermi 2 Intention to Implement GE Hitachi Simplified Stability Solution Mr. Downs, I am writing you to communicate DTE Energy Companys interest in the review of Licensing Topical Report NEDE-33766P for the GE Hitachi Simplified Stability Solution (GS3). At DTE Energys Fermi 2 Power Plant, we believe that GS3 represents a significant improvement over the current stability methodology and plan to implement this new stability option as soon as final NRC approval is obtained. GS3 will have a positive impact on simplified reactor operation. Additionally, a lower stability based Operating Limit Minimum Critical Power Ratio can be leveraged to reduce fuel cost which benefits our ratepayers.

It is our desire that the review of this submittal receive an appropriately high level of priority by the NRC.
