L-2013-278 Enclosure Page I of 2 Reply to Request for Additional Information - License Amendment Request and 10 CFR 50.46 and 10 CFR 50 Appendix K Exemption Request - M5 Fuel Rod Cladding The US NRC issued the following RAI:

Generic Letter (GL) 88-16 "Removal of Cycle-Specific Parameter Limits from Technical Specifications [TSs]" provides guidance for the preparation of a license amendment request to modify TSs that have cycle-specific parameter limits. An acceptable alternative to specifying the values of cycle-specific parameter limits in TSs consists of: (1) the addition of the definition of a named formal report that includes the values of cycle-specific parameter limits that have been established using a Nuclear Regulatory Commission (NRC) approved methodology and consistent with all applicable limits of the safety analysis, (2) the addition of an administrative reporting requirement to submit the formal report on cycle-specific parameter limits to the Commission for information, and (3) the modification of individual TSs to note that cycle-specific parameters shall be maintained within the limits provided in the defined formal report. GL 88-16 further clarifies that in Core Operating Limits Report (COLR) TS [6.9-x] core operating limits shall be established and documented in the COLR before each reload cycle or any remaining part of a reload cycle. The analytical methods used to determine the core operating limits shall be those previously reviewed and approved by NRC.

Based on the GL 88-16 guidance, TS 6.9. 1.1 1.b listed all approved methodologies to support all cycle-specific core operating parameters listed in TS 6.9. 1.11.a. Therefore, both TSs 6.9. 1. 11.a and 6.9. 1.11. b in COLR TSs establish a part of an acceptable alternative as stated in item (1) above. Please provide a description and the rationale for the parameters that will be detailed by BAW-1 0240(P)(A) Revision 0, "Incorporation of M5 Properties in Framatome ANP Approved Methods" in the TSs.

FPL RAI Response The rationale for including BAW-10240(P)(A), Revision 0 (Reference 1), in the list of Core Operating Limits Report (COLR) methodologies in TS 6.9.1.11.b is as follows:

1. NRC Final Safety Evaluation (SE) for Topical Report BAW-10240(P) (Reference 2) approved the incorporation of M5 properties in Framatome ANP approved methods, namely the mechanical analysis methodology (Reference 3), the Small Break LOCA (SBLOCA) methodology (Reference 4) and the non-LOCA methodologies (References 5 and 6).

BAW-10240(P)(A) provides the basis for using these methodologies for the applicable analyses to support the COLR limits, stated below in Item 3, for the fuel with M5 cladding.

2. The methodologies in References 3, 4, 5 and 6 are currently listed in TS 6.9.1.11.b (as stated below in References 3, 7, 8 and 6, respectively) as approved in the Extended Power Uprate (EPU) Amendment # 213. These methodologies are used to support the cycle-specific limits for the COLR parameters (see Item 3) listed in TS 6.9.1.11.a.

L-2013-278 Enclosure Page 2of 2

3. The methodologies in References 3, 6, 7 and 8 are used to verify or establish limits for the following COLR parameters:
a. Shutdown Margin,
b. Moderator Temperature Coefficient,
c. DNB Parameters,
d. Total Integrated Radial Peaking factor,
e. Linear Heat rate,
f.

CEA Insertion Limits.

4. Based on the GL 88-16 guidance, TS 6.9.1.11.b listed all approved methodologies to support cycle-specific COLR limits listed in TS 6.9.1.11.a. Since the Reference 1 Topical Report, BAW-10240(P) Revision 0 will be used in conjunction with the above specified COLR methodologies, to support the cycle-specific COLR limits for the parameters stated in Item 3 above, it is considered appropriate to include the Reference 1 Topical Report in the list of COLR methodologies in TS 6.9.1.11.b.
