REQUESTS FOR ADDITIONAL INFORMATION DAVIS-BESSE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION JUNE 15, 2011 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of FirstEnergy Nuclear Operating Company (FENOC or the applicant) held a telephone conference call on June 15,2011, to discuss and clarify the following responses to requests for additional information (RAls) concerning the license renewal application (LRA).

Response to RAls 2.3.3.11-01 and 2.3.3.12-01 on April 15, 2011 Discussion: The staff stated that, in the applicant's response to RAls 2.3.3.11-01 and 2.3.3.12-01 dated April 15, 2011, that fluid level gauge and sight glass components are excluded from aging management review (AMR) per 10 CFR 54.21(a)(1)(i), as "water level indicators." However, 10 CFR 54.21(a)(1)(i) specifies that AMR applies to components "that perform an intended function without moving parts or without a change in configuration or properties." The exclusions from AMR are intended for components that actively perform an intended function. The staff's expectation is that the fluid level gauge and sight glass perform their intended function without moving parts or a change in configuration, and additionally constitute part of the pressure boundary for their associated tanks. As such, they should have been included in the AMR.

The applicant stated that this was an error. The applicant stated that fluid level gauge and sight glass components should be included in the AMR. The staff agreed with the applicant, in that the applicant should revise its original response. A submittal date for the response will be discussed amongst the FENOC license renewal project manager and the NRC project manager on Friday, June 17, 2011.

Action: Applicant will supplement the response to RAls with a submittal date to be determined on June 17, 2011.

Response to RAI3.1.70-1 Discussion: The staff stated that by letter dated June 3, 2011, the applicant responded to RAI 3.1.1.70-1 and, in its response, confirmed that the Small Bore Class 1 Piping Inspection Program is credited to manage cracking due to flaw growth, stress corrosion cracking, and intergranular attack of the stainless steel and cast austenitic stainless steel (CASS) valve bodies less than 4 inches. The applicant also indicated that the Small Bore Class 1 Piping Inspection is a one-time inspection that will be designed to detect cracking of small bore ASME Code Class 1 piping less than 4 inches nominal pipe size (less than NPS 4) and greater than or equal to NPS 1, which includes pipe, fittings, and branch connections, and all full and partial penetration (socket) welds. However, the staff noted that neither the applicant's response to RAI 3.1.1.70-1 nor the technical information in the LRA addresses how the Small Bore Class 1 Piping Inspection Program manages the aging effect of the valve bodies less than 4 inches.

The applicant indicated that the original RAI was misinterpreted and the previous response needed correction in order to clarify that the small-bore valve bodies are not included in the ENCLOSURE 2

-2 scope of the Small Bore Class 1 Piping Inspection Program. The applicant also indicated that it uses the Inservice Inspection (lSI) Program to manage the aging effect of the small-bore valve bodies. In addition, the applicant confirmed that the "flaw" described in the terminology "flaw growth" refers to a hypothetical flaw, which might have a potential for further growth.

Action: The applicant will supplement its previous response to the RAI. The submittal of the supplemental information is scheduled for June 24, 2011.

There was no further discussion and the call was concluded.
