NRC Introduction By letter dated March 5, 2018, Tennessee Valley Authority (TVA), the licensee for Watts Bar Nuclear Plant, Unit 2 (WBN 2) requested to modify Condition 2.C(4) to Facility Operating License No. NPF-96 (Agencywide Document Access and Management System (ADAMS) Accession No. ML18064A192). The request was supplemented by letter dated April 27, 2018 (ML18137A193).
The NRC staff is reviewing the request and determined that additional information is required to complete its review.
The licensees April 27, 2018 letter referred to a proprietary evaluation, which was performed by Westinghouse Electric Company (WEC), and which the licensee stated was applicable to WBN Unit 2. This evaluation, included as Appendix B to LTR-NRC-12-18, is referenced in the below request (ML12053A105).
Regulatory Basis Because the simulation of the fuel element is an integral part of plant safety analyses, the NRC staff review of the proposed license condition revision is based on numerous General Design Criteria (GDCs) set forth in Appendix A to title 10 of the Code of Federal Regulations, part 50 (10 CFR 50). The NRC staff review is based on guidance and acceptance criteria provided in specific sections of Chapters 4, Reactor, and 15, Transient and Accident Analysis, of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Reactors, Light Water Reactor Edition.
The regulatory requirements in aggregate generally require the reactor fuel, coolant, and protection systems to be designed and operated with sufficient margins to safety to limit the postulated consequences of anticipated operational occurrences and infrequent events. The following GDC are applicable:
- GDC 20 requires automatic initiation of the reactivity control systems (RCSs) to assure that acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences and to assure automatic operation of systems and components important to safety occurs under accident conditions.
- GDC 25 requires that no single malfunction of the RCSs, excluding ejection or dropout, causes violation of the acceptable fuel design limits.
- GDC 26 requires that two independent RCSs of different design be provided, and that each system have the capability to control the rate of reactivity changes resulting from planned, normal power changes. One of the systems must be capable of reliably controlling anticipated operational occurrences. In addition, one of the systems must be capable of holding the reactor core subcritical under cold conditions.
CNL-18-116 Page E2-1 of 7
Enclosure 2
- GDC 28 requires that the effects of postulated reactivity accidents neither result in damage to the reactor coolant pressure boundary greater than limited local yielding, nor cause sufficient damage to impair significantly the capability to cool the core.
NRC RAI 1. Fuel Rod Cladding Stress and Strain
Background
Fuel rod design is addressed in Chapter 4.2 of the WBN dual-unit FSAR. The design criteria are discussed in Section 4.2.1.1.1, and a design description is provided in Section 4.2.1.2.1. Notably, the design description concludes with the safety objectives for fuel rod design. Among other things, the fuel rods are designed such that the cladding stress-strain limits are not exceeded for Condition I and II events.
In Appendix B to WEC Letter LTR-NRC-12-18, WEC notes that ((
))
The evaluation described above indicates several ways, in which TCD effects may be accommodated with respect to cladding stress and strain limits. However, it provides no specific or quantitative information to indicate that the evaluation would apply to WNB Unit 2. It also does not indicate the means by which TCD would be accommodated with regard to the WBN Unit 2 licensing basis, including the acceptance criteria applicable to that plant.
Request Demonstrate that, when accounting for the effects of TCD on fuel rod cladding stress and strain, the current acceptance criteria continue to be met, or that the application of newer, less-restrictive acceptance criteria provides sufficient margin to offset the effects of TCD.
TVA Response to RAI 1 Section 7.4.1 of Reference 1 discusses the new cladding stress criterion, which is based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) guidelines. As shown in Table 7.4.1-2, [
] The new cladding stress criterion is not affected by TCD.
Section 7.4.2 of Reference 1 discusses the new cladding strain criterion. The acceptance limit for cladding strain is that the total tensile strain, elastic plus plastic, due to uniform cylindrical fuel pellet deformation during any single Condition I or II transient shall be less than one percent (%) from the pre-transient value. Transient cladding strain margins were evaluated for WBN Unit 2 using PAD5, which was generically approved and explicitly accounts for the effects of TCD. [

NRC RAI 2. Main Steamline Break
Background
The main steamline break (MSLB) event is described in Section 15.4.2 of the Watts Bar Nuclear (WBN) Dual-Unit Updated Final Safety Analysis Report (UFSAR). The MSLB involves the rupture of a main steamline, followed by overcooling of the reactor coolant system (RCS). If the MSLB occurs at hot zero power (HZP) conditions, the core can return to power conditions, and if the MSLB occurs at hot full power (HFP) conditions, the core can enter an overpower condition. The licensing basis analysis for WBN Unit 2 assumes the plant is initially in a HZP condition, and departure from nucleate boiling (DNB) is evaluated at the limiting statepoint associated with that condition. The analysis confirms that DNB ratio (DNBR) remains above the applicable limit and fuel integrity is maintained throughout the event. Page 15.4-35 of the UFSAR notes that:
Both [analyzed MSLB cases] assume initial hot shutdown conditions at time zero since this represents the most limiting initial condition. Should the reactor be just critical or operating at power at the time of a steam line break, the reactor will be tripped by the normal overpower protections system when power level reaches a trip point. Following a trip at power the reactor coolant system contains more stored energy than at no load, the average coolant temperature is higher than at no load and there is appreciable energy stored in the fuel. Thus, the additional stored energy is removed via the cooldown caused by the steam line break before the no load conditions of RCS temperature and shutdown margin assumed in the analyses are reached.
As to the MSLB analyses, WEC stated in Table B.1 of LTR-NRC-12-18 that ((
))
The WBN2 licensing basis indicates that the results of an HFP MSLB would be bounded by the HZP event that is explicitly analyzed as described in UFSAR Section 15.4.2. However, the rationale reflects consideration of thermal energy sources like core stored energy that would be increased when TCD is taken into account. The information that TVA referenced in the WEC letter also indicates that (( )). In CNL-18-116 Page E2-3 of 7
Enclosure 2 Supplement 24 to NUREG-0847, Safety Evaluation Report Related to the Operation of Watts Bar Nuclear Plant, Unit 2, the NRC staff noted that the basis for not analyzing an HFP MSLB included the NRC-approved topical report WCAP-8745-P-A, Design Bases for the Thermal Overpower T and Overtemperature T Trip. This topical report includes information indicating that the OPT trip provides adequate protection for an MSLB event from HFP conditions.
Request Provide information to demonstrate that the OPT trip provides adequate protection from unacceptable consequences, such as fuel melt, following a postulated MSLB from HFP conditions.
Consider specifically that TCD has two effects: increasing stored energy in the core as discussed in WBN FSAR Section 15.4.2, and increased (( )) as discussed in Table B.1 of WEC letter LTR-NRC-12-18. Describe the extent to which existing or additional margin offsets, such as peaking factor burndown limits, are necessary to ensure (( ] is precluded.
TVA Response to RAI 2 Although a full power steamline break event is not presented in the WBN dual-unit Updated Final Safety Analysis Report (UFSAR), the event is analyzed for WBN Unit 2 to address the concerns outlined in Reference 1 related to non-safety grade equipment being subjected to an adverse environment from high-energy line breaks inside or outside containment. Specifically, Reference 1 postulated that a high-energy steamline break could cause the automatic rod control system cabling and/or related equipment to fail and subsequently cause the rods to withdraw from the core. Such a rod withdrawal, along with the reactor coolant system cooldown due to the steamline break, would lead to a rapid power excursion in which the overpower T (OPT) reactor trip setpoint would be reached. Therefore, an analysis of a steamline break at power with coincident rod withdrawal (SLB w/ RWAP) is performed for WBN Unit 2 to confirm that the OPT reactor trip function provides adequate protection from unacceptable consequences during a steamline break event from hot full power conditions.
The WBN Unit 2 SLB w/ RWAP event was reanalyzed using the revised LOFTRAN code input to account for the effects of fuel TCD. Fuel TCD has the effect of [
] through a reduction in uranium dioxide (UO2) conductivity with burnup. This effect was accounted for in the LOFTRAN analysis through the use of revised inputs for [
]
generated by the PAD5 fuel performance code (Reference 2). Cases were analyzed at [
] to ensure that the limiting case was identified. However, no credit was taken in the LOFTRAN analysis for [
].
The event was analyzed to demonstrate that the peak fuel linear heat generation rate remained below a value that would cause fuel melting (i.e., power-to-melt limit expressed in terms of [ ]),
and that the minimum departure from nucleate boiling ratio (DNBR) remained above the applicable safety analysis limit (SAL) value. For this analysis, the power-to-melt limit was redefined as a
[ ].
Specifically, the power-to-melt limit is [
] The DNBR SAL of [ ].
CNL-18-116 Page E2-4 of 7
Enclosure 2 The limiting results from the revised analysis are presented in Table 2. Confirmations that no fuel centerline melt occurs and that the DNBR SAL is met for the SLB w/ RWAP event are typically performed on a reload basis by [
], and consistent with the current core design methodology in Reference 3. Cycle specific analyses for Cycles 1 and 2 showed that with consideration of the models and methods in Reference 2 the [
]. The fuel melt limit for SLB w/ RWAP was met with consideration of the fuel TCD, using the models and methods defined in Reference 2 [
]. The minimum DNBR values calculated for the [ ]
cases remained well above the DNBR SAL.
Therefore, the effects of fuel TCD can be accommodated for the SLB w/ RWAP accident for WBN Unit 2.

Background
The control rod ejection accident is described in Section 15.4.6 of the Watts Bar UFSAR. Section 15.4.6.1.2 provides the acceptance criteria for the event, which include the following:
- The average fuel pellet enthalpy at the hot spot must be below 225 calories per gram for unirradiated fuel, and below 200 calories per gram for irradiated fuel.
- The peak reactor coolant pressure must not exceed the faulted condition stress limits,
- Fuel melting must be less than the innermost 10-percent of the fuel pellet at the hot spot.
The event is analyzed for WBN using the TWINKLE spatial kinetics code for the average core transient analysis, and the hot spot analysis is performed using FACTRAN. The hot spot analysis, in particular, has the potential to be affected by TCD. Specifically, ((
)) affected by TCD, according to LTR-NRC-12-18.
CNL-18-116 Page E2-5 of 7
Enclosure 2 Request Provide updated analyses of the hot spot rod ejection event for end-of-life conditions to show that the licensing basis acceptance criteria remain satisfied when accounting for the effects of TCD.
TVA Response to RAI 3 The WBN Unit 2 end-of-cycle-life (EOL) rod ejection cases were reanalyzed using TWINKLE and FACTRAN. The FACTRAN code inputs were revised to account for the effects of fuel thermal conductivity degradation (TCD) in the hot spot analysis. The revised inputs were based on the models and methods defined in Reference 1. Specifically, the input changes included [
] for both the HFP and hot zero power (HZP) cases. For the HFP case, [
].
The HZP case was based on the [
.]
The results from the revised analysis are compared to the results of the UFSAR analysis in Table 3. The peak reactor coolant pressure criterion was generically addressed in Reference 2, as noted in UFSAR Section 15.4.6.1.2. Based on the generic work, TVA concluded that the rod ejection event is not limiting with respect to reactor coolant pressure. [
] For this reason, the reactor coolant pressure criterion is not explicitly included in Table 3. The results from the revised analysis demonstrate that all licensing basis acceptance criteria continue to be satisfied. Therefore, TVA concluded that the effects of fuel TCD can be accommodated for the rod ejection accident for WBN Unit 2.

3 CAW-18-4813 (1) I am Manager, Fuels Licensing and Regulatory Support, Westinghouse Electric Company LLC (Westinghouse), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of Westinghouse.
(2) I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Nuclear Regulatory Commissions (Commissions) regulations and in conjunction with the Westinghouse Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.
(3) I have personal knowledge of the criteria and procedures utilized by Westinghouse in designating information as a trade secret, privileged or as confidential commercial or financial information.
(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of the Commissions regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.
(i) The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.
(ii) The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine when and whether to hold certain types of information in confidence. The application of that system and the substance of that system constitute Westinghouse policy and provide the rational basis required.
Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows:
(a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of

4 CAW-18-4813 Westinghouses competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.
(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage (e.g., by optimization or improved marketability).
(c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.
(d) It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.
(e) It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.
(f) It contains patentable ideas, for which patent protection may be desirable.
(iii) There are sound policy reasons behind the Westinghouse system which include the following:
(a) The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors. It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.
(b) It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.
(c) Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.
- This record was final approved on 9/28/2018 8:56:49 AM. (This statement was added by the PRIME system upon its validation)
5 CAW-18-4813 (d) Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage. If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.
(e) Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.
(f) The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.
(iv) The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Section 2.390, is to be received in confidence by the Commission.
(v) The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.
(vi) The proprietary information sought to be withheld in this submittal is that which is appropriately marked in WAT-D-12464 P-Attachment, Westinghouse Responses to NRC Request for Additional Information Regarding the Application to Revise Watts Bar Nuclear Plant Unit 2 - License Condition 2.C(4) PAD4TCD (391-WBN-TS-18-03), EPID L-2018-LLA-0051 (Proprietary), for submittal to the Commission, being transmitted by Tennessee Valley Authority (TVA) letter. The proprietary information as submitted by Westinghouse is that associated with NRCs review of TVAs application to revise the Watts Bar Nuclear Plant Unit 2 License Condition 2.C(4), and may be used only for that purpose.
(a) This information is part of that which will enable Westinghouse to support the NRCs review of TVAs application to revise License Condition 2.C(4).
- This record was final approved on 9/28/2018 8:56:49 AM. (This statement was added by the PRIME system upon its validation)
6 CAW-18-4813 (b) Further, this information has substantial commercial value as follows:
(i) Westinghouse plans to sell the use of similar information to its customers for the purpose of future NRC reviews regarding thermal conductivity degradation.
(ii) Westinghouse can sell support and defense of industry guidelines and acceptance criteria for plant-specific applications.
(iii) The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by Westinghouse.
Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar technical evaluation justifications and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.
The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.
In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.
Further the deponent sayeth not.
