PALISADES PLANT DOCKET NO. 50-255

1.0 INTRODUCTION

By letter to the Nuclear Regulatory Commission (NRC, the Commission) dated November 6, 2006, as supplemented by letters dated August 10, 2007, and December 20, 2007 (Agencywide Documents and Access Management System (ADAMS) Accession Nos. ML063180359, ML072260542, and ML080080470, respectively), Entergy Nuclear Operations, Inc. (the licensee), requested changes to the technical specifications (TSs) for the Palisades Nuclear Plant (PNP). The proposed changes would revise Appendix A, TS, Core Operating Limits Report (COLR) analytical methods referenced in TS 5.6.5.b to add EMF-2103 (P)(A), Realistic Large Break LOCA Methodology for Pressurized Water Reactors. The licensees submittal contained the technical report BAW-2501 (P) Revision 1 Reference (Ref. 3) describing PNPs Large Break Loss-of-Coolant Accident (LBLOCA) analyses performed using the EMF-2103 best estimate (BE) LBLOCA methodology. The supplements to the application provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the NRC staffs original proposed no significant hazards consideration determination as published in the Federal Register on December 19, 2006 (71 FR 75995).

2.0 REGULATORY EVALUATION

Section 50.46 of Title 10 of the Code of Federal Regulations (10 CFR), Acceptance criteria for emergency core cooling systems for light-water nuclear power reactors, specifies requirements for the acceptability of the emergency core cooling system. Paragraphs 50.46(a)(1)(i) and 50.46(a)(1)(ii) of 10 CFR specify alternative approaches to show compliance with the acceptance criteria of 10 CFR 50.46(b). Part 50 of 10 CFR, Appendix K, requires it to be assumed in the emergency core cooling system evaluation models that the reactor has been operating continuously at a power level at least 1.02 times the licensed power level (to allow for instrumentation error), with the maximum peaking factor allowed by the technical specifications.

Appendix K permits a lower assumed power level (but not less than the licensed power level) to be used provided the proposed alternative value has been demonstrated to account for uncertainties due to power level instrumentation error. A licensees compliance with the above criteria demonstrates the acceptability, following a LOCA, of (1) the peak calculated cladding temperature, (2) the maximum cladding oxidation, (3) the maximum hydrogen generation, and (4) the capability to maintain a coolable geometry, and (5) the capability to maintain long-term core cooling.

As explained below, the NRC staff used these acceptance criteria in assessing the acceptability of the AREVA realistic LBLOCA (RLBLOCA) methodology for PNP. In its analysis of the licensees request, the NRC staff also reviewed the limitations and conditions stated in its previous safety evaluation dated April 19, 2003, (Ref. 2) in which the NRC staff approved the general AREVA RLBLOCA methodology and the range of parameters described in the AREVA RLBLOCA methodology topical report.

3.0 TECHNICAL EVALUATION

The licensees BE LBLOCA analyses were performed to demonstrate that the ECCS design would provide sufficient ECCS flow to transfer the heat from the reactor core following a LBLOCA and at a rate such that (1) fuel and clad damage that could interfere with continued effective core cooling would be prevented, and (2) the clad metal-water reaction would be limited to less than the amounts that would compromise cladding ductility and result in excessive hydrogen generation.

The NRC staff reviewed the analyses to assure that the safety functions could be accomplished, with appropriate consideration of single-failure, containment capabilities and loss of onsite or offsite electric power (i.e., assuming offsite electric power is not available, with onsite electric power available; or assuming onsite electric power is not available, with offsite electric power available).

The NRC staff reviewed the licensees demonstration evaluations of the ECCS performance analysis, done in accordance with the AREVA BE LBLOCA methodology, for PNP operating at its currently licensed core power of 2565.4 MWt. These specific analyses were performed to demonstrate the suitability of the AREVA methodology for application to PNP. Accordingly, it should be noted that this SE and the associated amendment apply only to use of the AREVA RLBLOCA methodology at PNP at the plants currently licensed power; the analysis herein does not address any future PNP power uprate. The staff also determined the specific analyses discussed herein to be acceptable and specifically applicable to PNP with respect to the fuel(s) identified in the Table 1 that follows. The BE LBLOCA analyses for PNP were conducted assuming that the plant uses cores containing M5 clad uranium oxide fuel assemblies.

In its November 6, 2006, submittal (Ref. 1), the licensee [NMC, Nuclear Management Company, LLC, licensee at the time of the submittal] stated, NMC and AREVA NP have ongoing processes that assure the ranges and values of input parameters for the Palisades RLBLOCA analysis bound those of the as-operated plant values. As discussed below, the staff finds that this statement, along with the NRC staffs prior generic approval of the AREVA RLBLOCA analysis methodology, provides assurance that the AREVA RLBLOCA analysis methodology and its LBLOCA analyses apply to PNP operated at its current licensed power level.

In its submittal, the licensee provided the results for the PNP RLBLOCA analyses (Ref. 3),

operating at the rated power of 2565.4 MWt (performed in accordance with the AREVA RLBLOCA methodology). The licensees results for the calculated peak cladding temperatures (PCTs), the maximum cladding oxidations (local), and the maximum core-wide cladding oxidations for PNP are provided in the following table along with the acceptance criteria of 10 CFR 50.46(b).

  • DEG/PD is a double ended guillotine break at the pump discharge.

In conjunction with the review of the licensing action request, the NRC staff noted that the licensees LBLOCA analyses for PNP ranged reactor core power. The NRC staff was concerned that the licensees approach was not consistent with 10 CFR Part 50, Appendix K, Section I.A in two respects: (1) the power was ranged to values lower than 100 percent of core power, and (2) the ranging of power incorrectly mixed two different statistical distributions, which adversely impacts the assumed power and the measurement uncertainty distribution associated with the licensed power. However, in its response, dated December 20, 2007 (Ref. 5), to a NRC question, the licensee noted that the peak cladding temperature case (and therefore the licensing basis case) identified in the analyses was calculated assuming a higher reactor power than required by the nominal peaking factor range approved in the NRC SER (Ref. 2). The NRC staff finds the use of this assumption to be conservative, and therefore concludes that the analysis is acceptable and in accordance with Appendix K.

The analyses also ranged the availability of offsite power, which is inconsistent with 10 CFR Part 50, Appendix A, General Design Criteria (GDC) 35. Pursuant to GDC 35, loss of on-site power and loss of off-site power should be analyzed independently. However, the NRC staff noted that PNP is not a GDC plant and reviewed the analysis accordingly. The NRC staff noted that, historically, the Palisades plant LBLOCA analyses have been performed using models conforming with the provisions of 10 CFR Part 50, Appendix K. Appendix K methodologies are more conservative than best estimate LOCA methodologies and assume loss of offsite power. Therefore, previous Palisades LOCA analyses using Appendix K methodologies provide qualitative support for the adequacy of the presently proposed BE LBLOCA analyses using the AREVA RLBLOCA methodology.

In another component of its review, the NRC staff noted that in its analyses the licensee did not address the concern that the fuel cladding may have pre-existing oxidation that must be considered in its LOCA analyses. In its November 6, 2006 submittal (Ref. 1), the licensee stated: The AREVA NP RLBLOCA methodology explicitly analyzes only fresh fuel assemblies.... Previous analyses showed that once-and twice-burnt fuel is not limiting up to peak rod average exposures of 62,000 Mwd/MTU.

As such, NRC staff considers the licensees estimate of oxidation resulting from the postulated LBLOCA alone to be very low for Zr-4 cladding (0.87 percent, without considering pre-LOCA oxidation and without considering oxidation on both inside and outside surfaces). Another factor that may contribute to the licensees low calculated oxidation level is the low calculated LBLOCA peak cladding temperature (PCT) 1751 o F. The low PCT for LBLOCA is, in turn, most likely the result of the accumulator pressure assumed in the analyses, the LBLOCA analysis methodologys use of the Forslund-Rohsenow heat transfer model, and the treatment of radiation heat transfer.

Nevertheless, the NRC staff considers that even if the calculated PCT were greater (by less than 50 oF) and local oxidation were reasonably greater, the total expected oxidation, including accounting for all factors discussed above, would still be less than the 17 percent limit specified in 10 CFR 50.46(b)(2).

The need to analyze core-wide oxidation relates to the amount of hydrogen generated during a LOCA. However, because hydrogen that may have been generated pre-LOCA (during normal operation) will be removed from the reactor coolant system throughout the operating cycle, the NRC staff noted that pre-existing oxidation does not contribute to the amount of hydrogen generated post-LOCA and, therefore, it does not need to be addressed further when determining whether the calculated total core-wide oxidation meets the 1.0 percent criterion of 10 CFR 50.46(b)(3).

The NRC staff review also focused on radiation heat transfer because PNP has cruciform control rods that are located outside the fuel assembly. The hottest fuel rods in this design radiate only to other hot fuel rods. In contrast, S-RELAP, the thermal hydraulic code used by the licensee, has been only shown to apply to fuel assemblies with control rods, water-filled hollow rods, and structural components that are internal to the assemblies, and can also act as heat sinks for the hottest rod(s). Therefore, the S-RELAP treatment of core radiative heat transfer is non-conservative for the PNP core design. However, based on the significant margins to limits for PCT, oxidation and hydrogen shown in the table above, the NRC staff finds that the limits specified in 10 CFR 50.46(b) are met.

As discussed previously, the licensee had AREVA conduct BE LBLOCA analyses for PNP operating at the current licensed power level of 2565.4 MWt using an NRC approved AREVA BE LBLOCA analysis methodology. Based on its independent review, the NRC staff concludes that the results of these analyses demonstrate that the acceptance criteria of 10 CFR 50.46(b)(1) through (b)(3) would not be exceeded during a LBLOCA for licensed power levels of up to 2565.4 MWt. Meeting these criteria provides reasonable assurance that at the current licensed power level the PNP core will be amenable to cooling as required by 10 CFR 50.46(b)(4). The capability of PNP 1 & 2 to satisfy the long term cooling requirements of 10 CFR 50.46(b)(5) is unaffected by this amendment.

3.1 Palisades Technical Specifications Change In support of its November 6, 2006, License Amendment Request (LAR) (Ref. 1) the licensee proposed to make amendments to the PNP Core Operating Limits Report (COLR) for the plant to reflect use of a new LBLOCA analysis methodology to perform LBLOCA analyses in support of PNP operation. The licensee also provided a proposed page TS 5.6.5 COLR, amended to reflect the implementation of EMF-2103 (P)(A) as the licensing basis LBLOCA methodology for

the PNP plant. The NRC staff reviewed the TS provision, assessed it for consistency against NUREG-1432, Revision 3 (Ref. 4), and found its content acceptable and compatible with a proposed COLR.

Proposed TS change:

The following reference is added:

20. EMF-2103 (P)(A), Realistic Large Break LOCA Methodology for Pressurized Water Reactors. (LCOs 3.1.6, 3.2.1, & 3.2.2)

This methodology was found to apply to all conventional Westinghouse, Combustion Engineering, and Babcock and Wilcox Pressurized Water Reactor (PWR) designs in the NRC generic SE of the EMF-2103 (P)(A) Revision 0 methodology. Therefore, the NRC staff concludes that the realistic LBLOCA methodology described in EMF-2103 (P)(A) Revision 0 is acceptable for application to PNP, which is a PWR of Combustion Engineering design, and for inclusion in TS for PNP. The above listed TS Ref. 20, was presented in the licensees submittal as a TS addition. This reference does not include the EMF-2103 revision number; nor does it include the date of approval for the methodology. The licensee will list the topical report, including the latest revision number (used at Palisades), and date of approval in the COLR for the PNP plant consistent with guidance provided in NUREG-1431.

The NRC staff finds that the EMF-2103 (P)(A) Revision 0 methodology is applicable to PNP, and that the limitations and conditions of the NRCs SE approving the EMF-2103 (P)(A) Revision 0 methodology were satisfied, for the present Palisades operating power. The NRC staff concludes that the proposed addition of EMF-2103 (P)(A) Revision 0 to Palisades TS is acceptable.

3.2 Summary Based on its review as discussed above, the NRC staff concluded that the AREVA BE LBLOCA analyses methodology, as described in EMF-2103 (P)(A) Revision 0 (Ref. 2), is acceptable for use by PNP in demonstrating compliance with the requirements of 10 CFR 50.46(b). The NRC staffs conclusion is based on having verified that the PNPs design is among the designs for which AREVA BE LBLOCA application was approved.

The NRC staffs review of the acceptability of the AREVA BE LBLOCA methodology for PNP focused on assuring that the licensee and its vendor have processes to assure that specific input parameters or bounding values and ranges (where appropriate) are used to conduct the PNP LBLOCA analyses, that the analyses will be conducted within the conditions and limitations of the NRC approved AREVA BE LBLOCA methodology, and that the results will satisfy the requirements of 10 CFR 50.46(b) for Palisades operating at its present licensed power.

This SE documents the NRC staff review and acceptance of the AREVA BE LBLOCA analysis methodology for application to PNP, for inclusion in the PNP TS 6.2.C and COLR, and of the specific LBLOCA analyses discussed above that were performed with the AREVA BE LBLOCA methodology for PNP operated at powers up to its licensed power level of 2565.4 MWt.

As noted above, this SE and the associated approvals apply only to using the AREVA Realistic LBLOCA methodology at PNP at the present power; the analysis does not address any future PNP power uprate.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Michigan State official was notified of the proposed issuance of the amendment. The Michigan State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (71 FR 75995). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
