| ENCLOSURE 1 RESPONSE TO NRC QUESTION REGARDING WATTS BAR NUCLEAR PLANT UNIT 1 REVISED CONTAINMENT ANALYSIS
| |
| | |
| Enclosure 1 Response to NRC Question Regarding Watts Bar Nuclear Plant Unit 1 Revised Containment Analysis NRC Question TVA Jetter dated September 11, 2015, Enclosure 1 (Westinghouse report WCAP-17834-P, Revision 1), Section 4.2, input assumption 12 states:
| |
| "The initial conditions in the containment are a temperature of 100°F in the lower compartment and dead-ended compartment, a temperature of 80°F in the upper compartment, and a temperature of 27°F in the ice condenser. The B0°F temperature in the upper compartment is a reduction from the 85°F technical specification limit to account for the upper plenum volume of the ice condenser which is included in the upper compartment volume for the analysis. .. ."
| |
| The NRG supplemental information request dated July 9, 2015, included the following request:
| |
| "The analysis for Unit 1 should also provide information consistent with the licensee's December 17, 2014, response to Request for Additional Information (RAJ) regarding Watts Bar Unit 2 Final Safety Analysis Report (FSAR), Amendment 112, Chapter 6, RAJ Number SCVB-RAl-3 (ADAMS Accession Number ML14352A248). In addition, consistent with Watts Bar Unit 2, please revisit the initial containment temperatures stated in assumption number (10) in Section 6.2.1.3.3 of the Watts Bar Unit 1 FSAR, and revise the containment analysis for conservatism based on the maximum containment air temperatures specified in TS 3.6.5. " [emphasis added]
| |
| It is not clear whether the sensitivity of initial upper, dead-ended, and lower compartment temperatures on the containment peak pressure is addressed in the TVA September 11, 2015, letter and enclosure. Did Westinghouse perform a sensitivity analysis by conservatively biasing the initial containment upper and lower compartment temperatures similar to the analysis performed for Unit 2, in which it was determined that using the initial temperature specified in TS 3. 6. 5 of 120°F for the lower and dead-ended compartments, and 110°F for the upper compartment resulted in higher containment peak pressure?
| |
| TVA Response A teleconference was held on September 17, 2015 between NRC and TVA to discuss the question. TVA was supported on the call by Westinghouse Electric Company (Westinghouse).
| |
| After discussion, TVA committed to provide the technical response provided by Westinghouse.
| |
| The following provides TVA's response to the NRC question regarding the Watts Bar Nuclear Plant (WBN) Unit 1 Revised Containment Analysis.
| |
| Although not stated in WCAP-17834-P Revision 2 [Reference 2 of cover letter],
| |
| containment initial temperature studies were performed for the WBN Unit 1 containment integrity analysis. The result is that minimum upper, lower, and dead-ended compartment temperatures were limiting with respect to peak containment pressure. The result of this sensitivity study is consistent with the containment initial conditions presented in WCAP-17834-P Revision 2 Section 4.2, which reflect technical specification minimum upper, lower, and dead-ended compartment temperatures.

| ==SUMMARY==
| |
| | |
| Long-term Loss-of-Coolant-Accident (LOCA) Mass and Energy (M&E) Release and Containment Integrity Analyses have been performed to support plant operation at Watts Bar Unit 1. The M&E releases were calculated for a spectrum of cases using the WCOBRA/TRAC LOCA M&E methodology, which was submitted to the NRC in May 2013 as WCAP-17721-P [1] and the final safety evaluation was received in August 2015 [21]. The containment responses were calculated with the LOTIC1 ice condenser containment code, documented in WCAP-8354-P-A [2].
| |
| The objective of this effort was to provide revised containment mass and energy release data using current Watts Bar Unit 1 specific information and more realistic models to support the containment integrity pressure response. The analyses used the WCAP-17721-P [1] mass and energy release model which yielded a maximum containment peak pressure of 9.36 psig (relative to the containment design pressure of 13.5 psig) for the double ended pump suction break with a loss of offsite power and an assumed failure of an emergency diesel generator. The assumed ice mass in containment was the current technical specification analytical minimum ice mass of 2.26x106 lbm (WBT-D-2751 [14]). In addition, the limiting mass and energy releases were input to a containment response calculation assuming an initial ice mass of 2.0x106 lbm initial ice mass. This yielded a peak containment pressure of 10.44 psig.
| |
| This revision includes the removal of revision bars and the addition of proprietary brackets throughout the document. No technical changes from Revision 1 of this report have been made.

| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-1 2 INTRODUCTION The design and licensing of nuclear power plants require that the containment be analyzed for pressure and temperature effects. The analyses include pressure and temperature transients which the containment might be exposed to as a result of postulated reactor coolant system (RCS) pipe break during plant operation. Containment integrity analyses are performed for ice condenser containment designs to determine the minimum analytical initial ice mass required, and to demonstrate the acceptability of the containment safeguards equipment to mitigate the postulated transient without exceeding the containment design pressure acceptance criteria (13.5 psig).
| |
| | |
| ==2.1 BACKGROUND==
| |
| | |
| In 2011, NSAL-11-5 [4] was issued to plants which use the Westinghouse WCAP-10325-P-A [5]
| |
| methodology to calculate LOCA mass and energy releases. NSAL-11-5 [4] identified penalties associated with various errors related to the mass and energy releases, and all errors affecting the Watts Bar Unit 1 analysis were (informally) evaluated. The result was an estimated ice mass penalty of approximately 140,000 lbm (WAT-D-11922 [6]). Further work showed that the current technical specification ice mass of 2.26x106 lbm (WBT-D-2751 [14]) could be maintained if containment spray switchover times occurred earlier in the transient. This work is documented in CN-CRA-11-32 [7].
| |
| In parallel with the work described in the paragraph above, Westinghouse has been actively developing a new LOCA M&E methodology using the WCOBRA/TRAC computer code. An overview of the WCOBRA/TRAC code is provided in WCAP-17721-P [1]. The new methodology mechanistically releases the stored RCS and steam generator (SG) energy. These new releases will delay ice bed meltout relative to the WCAP-10325-P-A [5] methodology at a given ice mass, thus reducing the calculated peak containment pressure.
| |
| Tennessee Valley Authority (TVA) requested an operability analysis using the WCOBRA/TRAC methodology in its current development state in 2012. This work is documented in CN-CRA-12-14 [8],
| |
| and the results were transmitted to TVA via WAT-D-11961 [18]. The result of the WCOBRA/TRAC operability analysis was that the current technical specification ice mass of 2.26x106 lbm is sufficient to meet all key acceptance criteria.
| |
| Understanding that the WCOBRA/TRAC LOCA M&E methodology was still under development, TVA contracted Westinghouse to perform the work scope defined in LTR-AMER-MKG-12-1181, Revisions 2 [9] and 3 [10]. This work scope was to perform a new analysis of record (AOR) for Watts Bar Unit 1 (as opposed to the operability analysis described above) using WCOBRA/TRAC and LOTIC1.
| |
| The WCOBRA/TRAC analysis for Watts Bar Unit 1 was to be done consistent with the as developed and submitted WCOBRA/TRAC LOCA M&E methodology that is documented in WCAP-17721-P [1].
| |
| While the AOR work was underway, it was agreed that the Watts Bar Unit 1 analysis would be used to support the WCOBRA/TRAC LOCA M&E topical report, WCAP-17721 [1]. This work has been completed and is captured in the Electronic Document Management System (EDMS) as CN-CRA-12-31, Revision 0 [11].
| |
| WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-2 This analysis was further updated to account for the shared component cooling system and updates which were needed as a result of RAIs and the finalization of the WCOBRA/TRAC LOCA M&E topical report.
| |
| This included updated material properties, additional uncertainty included in the fuel temperatures, and turning on critical heat flux flags [21]. This work has been completed and is captured in EDMS as CN-CRA-15-2, Revision 0 [20].
| |
| 2.2 PURPOSE OF ANALYSIS The purpose of this analysis was to calculate the long-term LOCA mass and energy releases and the subsequent containment integrity response in order to demonstrate support for plant operation at the current Watts Bar Unit 1 technical specification minimum ice mass of 2.26x106 lbm. In addition, sensitivity studies were included to determine the magnitude of potential ice mass reductions. The conclusions demonstrated, with respect to LOCA, that containment integrity has not been compromised.
| |
| In addition, since the LOCA event requires the greatest amount of ice compared to other accident scenarios, the initial ice mass, based on the LOCA results, is also acceptable for the other accident scenarios.
| |
| Rupture of any of the piping carrying pressurized high-temperature reactor coolant water, termed a LOCA, will result in a release of steam and water into the containment. This, in turn, will result in an increase in the containment pressure and temperature. The mass and energy release rates described in this document form the basis for further computations to evaluate the containment response following a postulated accident to satisfy the Nuclear Regulatory Commission (NRC) acceptance criteria, General Design Criterion 38. Section 3 presents the long-term mass and energy release analysis for the containment pressurization evaluations. Section 4 presents the results of the containment response calculations. Section 5 provides containment response results with a reduced initial ice mass of 2.0x106 lbm. The list of references is provided in Section 7.
| |
| 2.3 SYSTEM CHARACTERIZATION AND MODELING ASSUMPTIONS The mass and energy release analysis is sensitive to the assumed characteristics of various plant systems, in addition to other key modeling assumptions. Some of these items are related to the RCS initial conditions, core decay heat, safety injection flow, and metal and steam generator heat release modeling.
| |
| These key characteristics and modeling assumptions are discussed below. Tables 3.8-1 through 3.8-3 present key data used in the analysis.
| |
| CN-CRA-12-14 [8] describes the steady state modeling in detail, and then the model was further updated in CN-CRA-15-2 [20]. The rated core thermal power includes an [
| |
| ]a,c in the analysis. The initial fluid energy is based on coolant temperatures that are at the maximum levels attained in steady state operation. Additionally, an [
| |
| ]a,c The initial RCS pressure
| |
| [
| |
| ]a,c The selection of 2320 psia as the limiting pressure primarily affects the blowdown phase results. The RCS rapidly depressurizes from this value until the point at which it equilibrates with the containment pressure. The rate at which the RCS depressurizes is WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-3 initially more severe at the higher RCS pressure. Additionally the RCS has a higher fluid density at the higher pressure (assuming a constant temperature) and subsequently has a higher RCS mass available for releases. Thus, the 2320 psia initial pressure has been selected as the limiting case for the long-term mass and energy release calculations. These assumptions conservatively maximize the initial mass and energy in the RCS.
| |
| The fuel design features assumed for the long-term LOCA mass and energy release calculation conservatively maximize [
| |
| ]a,c Because of the change to the new WCOBRA/TRAC methodology, the entire break spectrum was reanalyzed. This included full double ended guillotine breaks in both the cold leg and pump suction leg, with both maximum and minimum safety injection flow rates. In the case of minimum safety injection flow rates, the assumed single failure was loss of a diesel generator. In the case of maximum safety injection flow rates, the assumed single failure was the loss of a containment spray pump. In all cases, a loss of offsite power at event initiation was assumed.
| |
| The following list summarizes the assumptions that were employed to ensure that the mass and energy releases were conservatively calculated, thereby maximizing the release to containment. [

| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-1 3 LONG TERM LOCA MASS AND ENERGY RELEASE ANALYSIS
| |
| | |
| ==3.1 INTRODUCTION==
| |
| | |
| The evaluation model used for the long-term LOCA mass and energy release calculations is described in WCAP-17721-P [1]. This evaluation model has been reviewed and the methodology has received the final safety evaluation report from the NRC in August 2015.
| |
| This report section presents the long-term LOCA mass and energy releases that were generated in support of Watts Bar Unit 1 for operation at the current technical specification minimum ice mass of 2.26x106 lbm. In addition, included in the reanalysis are containment integrity sensitivities intended to provide an approximation of the benefits to potential ice mass reductions provided by moving to the WCOBRA/TRAC M&E methodology. In all cases, LOTIC1 was used to calculate the LOCA containment response.
| |
| 3.2 LOCA MASS AND ENERGY RELEASE PHASES The containment system receives mass and energy releases following a postulated rupture in the RCS.
| |
| These releases continue over a time period, which, for the LOCA mass and energy analysis, is typically divided into four phases:
| |
| : 1. Blowdown: The period of time from accident initiation (when the reactor is at steady state operation) to the time that the lower plenum begins to re-pressurize after initial coolant evacuation.
| |
| : 2. Refill: The period of time when the reactor vessel lower plenum is being filled by accumulator and emergency core cooling system (ECCS) water. The WCOBRA/TRAC code mechanistically calculates this phase.
| |
| : 3. Reflood: The period of time that begins when the water from the reactor vessel lower plenum enters the core and ends when the core is completely quenched.
| |
| : 4. Post-Reflood: The period of time following the reflood phase. It is during this portion of the transient that (for the double ended cold leg (DECL) and double ended pump suction (DEPS) breaks) a two phase mixture exiting the core enters the steam generators, resulting in reverse heat transfer from the secondary side to the primary side. Heat transfer from the steam generator secondary metal to the fluid, and then from the fluid to the tubes, is accounted for in a mechanistic fashion.

| Unlike the currently approved Westinghouse LOCA M&E methodology, WCAP-10325-P-A [5], the WCAP-17721-P [1] methodology uses a single code for all phases of the LOCA transient through the time of peak containment pressure. After the peak pressure has occurred, a two-step approach is used to calculate the long term mass and energy releases.

| ]a,c 3.2.1 WCOBRA/TRAC Computer Code WCOBRA/TRAC consists of two primary source codes, COBRA-TF and TRAC-PD2. COBRA-TF is a three dimensional thermal hydraulic code that is used to model the vessel in detail, and TRAC-PD2 is a one dimensional code that is used to model loop piping, pumps, steam generators, and various boundary conditions. The two codes interface in the nozzle region where the vessel transitions to the hot and cold legs, as well as with the 1-D pipes used to model core bypass. The WCAP-17721-P [1] mass and energy release evaluation model is based on the WCOBRA/TRAC computer code. The WCOBRA/TRAC computer code is currently used as the pressurized water reactor (PWR) ECCS evaluation model by Westinghouse; it is fully capable of calculating the thermal/hydraulic RCS response to a large pipe rupture. The use of WCOBRA/TRAC for this application has been qualified by comparison with scalable test data covering the expected range of conditions and important phenomena. Modifications to WCOBRA/TRAC were required to model the specifics of importance to the LOCA M&E analysis, and these updates are discussed below.

| The WCOBRA/TRAC steam generator, modeled in accordance with the ECCS evaluation model, [
| |
| ]a,c The result is a computer code capable of modeling phenomena associated with the large break LOCA conditions that provides significant margin relative to the current WCAP-10325-P-A methodology [5] because the stored RCS and SG energy is released at a mechanistically calculated rate instead of forced out over a conservatively short duration.
| |
| WCOBRA/TRAC was modified to produce output better tailored for the LOCA M&E applications. This included updates to print stored RCS and SG metal and fluid energy levels, used as input to the enhanced steaming calculation. Mass and energy releases are written at user specified intervals. WCOBRA/TRAC was also modified to interface with the GOTHIC computer code, allowing the coupling of the mass and energy release code directly to the containment response code. At this time, Westinghouse does not currently have an NRC approved GOTHIC ice condenser model, but the capability exists to couple one to WCOBRA/TRAC should one ever be developed. The coupling would allow real time communication of containment backpressure and safety injection recirculation temperatures, avoiding bounding assumptions that are applied in the standalone cases discussed in this report.

| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-3 3.3 RCS MODEL DESCRIPTION Following the methodology outlined in WCAP-17721-P [1], the WCOBRA/TRAC ECCS evaluation model for Watts Bar Unit 1 was modified to function as a LOCA M&E analytical tool. This was a multi-step process that resulted in a balanced steady state model from which the transient runs could be initiated. The work was documented in CN-CRA-12-14 [8] and further updated in CN-CRA-15-2 [20].

| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-5 3.4 ACCEPTANCE CRITERIA FOR ANALYSIS A large-break LOCA accident is classified as an ANS Condition IV event, an infrequent fault. To satisfy the NRC acceptance criteria presented in the Standard Review Plan (SRP), Section 6.2.1.3 [12], the relevant requirements are documented in:
| |
| x 10 Code of Federal Regulations (CFR) 50, Appendix A x 10 CFR 50, Appendix K, Paragraph I.A To meet these requirements, the following must be addressed:
| |
| x Sources of energy x Break size and location x Calculation of each phase of the accident x Mass and energy release data Each of these items is addressed in the following sections.
| |
| 3.5 SOURCES OF MASS AND ENERGY The sources of mass and energy in the WCOBRA/TRAC M&E analysis are the following:
| |
| : 1. RCS water
| |
| : 2. Accumulator water
| |
| : 3. Pumped safety injection water
| |
| : 4. Decay heat
| |
| : 5. Core stored energy
| |
| : 6. RCS metal (including the SG tube metal)
| |
| : 7. Steam generator metal (including shell, wrapper, and internals)
| |
| : 8. Steam generator secondary fluid energy (liquid and steam)
| |
| All sources of mass and energy listed above are considered in the WCOBRA/TRAC portion of the analysis. The water in the RCS, accumulators, safety injection boundary conditions, and SG secondary is explicitly modeled. Core decay heat (including feedback effects during blowdown) is included in the WCOBRA/TRAC fuel rod model. The fuel rod model also includes an energy term to represent core stored energy. The RCS and SG metal, and the associated heat transfer from these sources, is modeled in the WCOBRA/TRAC analysis. [
| |
| ]a,c WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-6 3.6 BREAK SIZES AND LOCATIONS Three distinct locations in the RCS loop can be postulated for pipe rupture:
| |
| : 1. Hot leg (between vessel and steam generator),
| |
| : 2. Cold leg (between pump and vessel), or
| |
| : 3. Pump suction (between SG and pump).
| |
| The double ended pump suction guillotine break is analyzed for Watts Bar Unit 1 (using the current WCAP-10325-P-A [5] methodology). This break is limiting for the long term response and defines the current minimum ice weight. Moving to the WCAP-17721-P [1] WCOBRA/TRAC methodology, full double ended ruptures were analyzed in the cold leg and the pump suction leg, each with 1 and 2 trains of safety injection, to cover the spectrum of possible limiting break locations for Watts Bar Unit 1 in the context of the new methodology.
| |
| Full double ended double ruptures of the cold leg and pump suction leg behave similarly, or more specifically, both behave dissimilarly from a double ended rupture of the hot leg. This is because the hot leg break provides a direct vent path to containment for the core exit flow during the post-blowdown phases. This has the effect of allowing the two phase mixture to bypass the steam generators, yielding significantly reduced integrated energy release in the long term. While the blowdown has the potential to be more severe for the hot leg break, ice condenser plants are inherently limited by the long term mass and energy releases after the ice bed is depleted. Therefore, the hot leg break has been excluded from the spectrum of runs. The double ended pump suction and double ended cold leg breaks both provide a mechanism to transport a two phase mixture to both the intact and broken steam generators, and so both have been analyzed with WCOBRA/TRAC.
| |
| 3.7 APPLICATION OF SINGLE FAILURE CRITERIA An inherent assumption in the generation of the mass and energy releases is that offsite power is lost. This results in the actuation of the emergency diesel generators, required to power the safety injection system.
| |
| This is not an issue for the blowdown period, which is limited by the compression peak pressure.
| |
| In the case of minimum safeguards, the single failure postulated to occur is the loss of an emergency diesel generator. This results in the loss of one pumped safety injection train (ECCS pumps and heat exchangers) thereby minimizing the safety injection flow. Assumptions relative to refueling water storage tank (RWST) drain down and subsequent ECCS switchover are biased to achieve the earliest switchover of the ECCS relative to a single-train failure scenario. Early switchover of the ECCS results in a higher core decay heat at the switchover time. Since recirculation cooling is limited by cooling of the ECCS water via the residual heat removal (RHR) heat exchangers, an earlier switchover time is considered to be conservative for LOCA mass and energy releases.
| |
| In the case of maximum safeguards, the single failure postulated to occur is the failure of a containment spray pump to start. This results in only a single train of containment spray being available (i.e., no change to containment spray flow from the minimum safeguards case). The safety injection flow rates are based upon operation of two trains of pumps and heat exchangers. The operation of two trains of safety injection increases the drain rate of the RWST, and the switchover to recirculation times for the pumps are WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-7 correspondingly earlier compared to the minimum safeguards case. The maximum safeguards cases were not updated as they have been shown to be non-limiting with respect to containment peak pressure in previous analyses [11].
| |
| 3.8 MASS AND ENERGY RELEASE DATA The LOTIC1 containment analysis methodology treats blowdown mass and energy releases separate from the long term post-blowdown releases. Sections 3.8.1 and 3.8.2 address the blowdown and long term WCOBRA/TRAC mass and energy releases, respectively. Table 3.8-9 contains the sequence of events for the DEPS LOCA event.
| |
| 3.8.1 Blowdown Mass and Energy Release Data The blowdown mass and energy releases from each of the WCOBRA/TRAC runs were extracted from the code output. The blowdown mass and energy releases for each of the cases are shown below in Table 3.8-4 through Table 3.8-5. The end of blowdown, as defined in the context of the WCOBRA/TRAC LOCA M&E methodology, is defined as the point in time at which the vessel lower plenum begins to re-pressurize.
| |
| 3.8.2 Long Term WC/T Mass and Energy Release Data The WCOBRA/TRAC mass and energy release calculation was run through 20,000 seconds for each of the break cases. Twenty thousand seconds was long enough to melt the ice bed, calculate a containment peak pressure, and establish a substantial period of containment depressurization. WCOBRA/TRAC allows the user to select intervals at which [ ]a,c These data are then rearranged into columns of mass and energy rates for each side of the break. The long term M&E data for each of the cases are presented in Table 3.8-6 through Table 3.8-7.
| |
| 3.8.3 Decay Heat Model The Nuclear Power Plant Standards Committee (NUPPSCO) of the American Nuclear Society (ANS) issued ANS Standard 5.1 [19] in August 1979 for the determination of decay heat. This standard was used in the LOCA mass and energy release model in the approved topical report, WCAP-10325-P-A [5]. This decay heat curve is presented in Table 3.8-2. This curve was used in the final and most limiting minimum safeguards DEPS WCOBRA/TRAC run. Also important to note is that early in the transient, during blowdown, there are moderator feedback effects that need to be accounted for. Therefore, during blowdown, the WCOBRA/TRAC calculated core power was used.
| |
| Significant assumptions in the generation of the decay heat curve are listed below.
| |
| : 1. The highest decay heat release rates come from the fission of U-238 nuclei. Thus, to maximize the decay heat rate a maximum value (8%) has been assumed for the U-238 fission fraction.
| |
| : 2. The second highest decay heat release rate comes from the fission of U-235 nuclei. Therefore, the remaining fission fraction (92%) has been assumed for U-235.
| |
| WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-8
| |
| : 3. The factor which accounts for neutron capture in fission products has been taken directly from Table 10 of the standard.
| |
| : 4. The number of atoms of Pu-239 produced per second has been assumed to be 70% of the fission rate.
| |
| : 5. The total recoverable energy associated with one fission has been assumed to be 200 MeV/fission.
| |
| : 6. The fuel has been assumed to at full power for 108 seconds.
| |
| : 7. 2 uncertainty has been applied to the fission product decay. This accounts for a 98% confidence level.
| |
| 3.8.4 Long Term Steaming Calculations The limiting break location and single failure scenario was determined to be the double ended pump suction break with the failure of an emergency diesel generator to start. Minimum safety injection flows were conservatively assumed. This combination produced the highest containment peak pressure at the current technical specification minimum ice mass of 2.26x106 lbm. After the 20,000 second period with WCOBRA/TRAC mass and energy releases, it was necessary to [

| |
| | |
| ==4.1 DESCRIPTION==
| |
| OF LOTIC1 MODEL Early in the ice condenser development program it was recognized that there was a need for modeling of long-term ice condenser performance and that the model would have to have capabilities comparable to those of the dry containment (COCO) model. These capabilities would permit the model to be used to solve problems of containment design and to conservatively model the containment and safeguards systems. This has been accomplished in the development of the LOTIC1 computer code, described in WCAP-8354-P-A [2]. LOTIC1 has previously been applied to containment analyses for Watts Bar Unit 1, including the initial licensing.
| |
| The model of the containment consists of five distinct control volumes: the upper compartment, the lower compartment, the portion of the ice bed from which the ice has melted, the portion of the ice bed containing unmelted ice, and the dead-ended compartment. The ice condenser control volume with unmelted and melted ice is further subdivided into six sub-compartments to allow for maldistribution of break flow to the ice bed.
| |
| The conditions in these compartments are obtained as a function of time by the use of fundamental equations solved through numerical techniques. These equations are solved for three phases in time. Each phase corresponds to a distinct physical characteristic of the problem. Each of these phases has a unique set of simplifying assumptions based on results from the ice condenser test facility. These phases are the blowdown period, the depressurization period, and the long-term period.
| |
| The most significant simplification of the problem is the assumption that the total pressure in the containment is uniform. This assumption is justified by the fact that after the initial blowdown of the RCS, the remaining mass and energy released from this system into the containment is small and very slowly changing. The resulting flow rates between the control volumes will also be relatively small. These flow rates are unable to maintain significant pressure differences between the compartments.
| |
| In the control volumes, which are always assumed to be saturated, steam and air are assumed to be uniformly mixed and at the control volume temperature. The air is considered a perfect gas, and the thermodynamic properties of steam are taken from the American Society of Mechanical Engineers (ASME) steam table.
| |
| The condensation of steam is assumed to take place in a condensing node located, for the purpose of calculation, between the two control volumes in the ice storage compartment. The exit temperature of the air leaving this node is set to a specific value that is equal to the temperature of the ice-filled control volume of the ice storage compartment. Lower compartment exit temperature is used if the ice bed section is melted.

| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 4-2 4.2 CONTAINMENT PEAK PRESSURE CALCULATION The following are the major input assumptions used in the LOTIC-1 analysis for the limiting DEPS minimum safeguards break. With the exception of the mass and energy release updates, the limiting DEPS minimum safeguards LOTIC1 model input has been updated from the WCAP-10325-P-A analysis of record, CN-CRA-10-16 [3] based on the updated input request response documented in W-8218 [23].
| |
| The updated calculation is documented in CN-CRA-15-2 [20]. The results of this analysis were transmitted to TVA via WBT-D-5427 [24].
| |
| : 1. Minimum safeguards are assumed, that is, a single train of emergency core cooling and a single train of containment spray is assumed to be available as a result of the failure to start of an emergency diesel generator (See Table 4.5-5).
| |
| : 2. 2.26x106 lbm of ice is initially in the ice condenser.
| |
| : 3. The DEPS minimum safeguards mass and energy releases described in Section 3.8 are used.
| |
| : 4. The blowdown period mass and energy from Table 3.8-4 is conservatively compressed into a 10-second period in order to melt an amount of ice consistent with the Waltz Mill ice condenser test, WCAP-8110 [13].
| |
| : 5. Blowdown and post-blowdown ice condenser drain temperatures of [ ]a,c are used, respectively. These values are based on the Waltz Mill ice condenser test data described in WCAP-8110 [13].
| |
| : 6. Nitrogen from the accumulators in the amount of 3961 lbm is included in the calculations.
| |
| : 7. Hydrogen gas was added to the containment in the amount of 25,230 standard cubic feet over 24 hours. Sources accounted for were radiolysis in the core and sump post-LOCA, corrosion of plant materials (aluminum, zinc, and painted surfaces in containment), reaction of 1% of the Zirconium fuel clad, and hydrogen gas dissolved in the RCS water. This bounds the Watts Bar Unit 1 tritium producing core design, WCAP-15699, Rev. 1 [16].
| |
| : 8. Essential service water temperature of 88°F is used for the spray heat exchanger and the component cooling heat exchanger.
| |
| : 9. The air return fan is effective 600 seconds after the transient is initiated.
| |
| : 10. No maldistribution of steam flow to the ice bed is assumed. This assumption is conservative and contributes to early ice bed melt out time.
| |
| : 11. No ice condenser bypass is assumed. This assumption depletes the ice in the shortest time and is thus conservative.
| |
| : 12. The initial conditions in the containment are a temperature of 100oF in the lower compartment and dead-ended compartment, a temperature of 80qF in the upper compartment, and a WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 4-3 temperature of 27qF in the ice condenser. The 80°F temperature in the upper compartment is a reduction from the 85°F technical specification limit to account for the upper plenum volume of the ice condenser which is included in the upper compartment volume for the analysis. The volume is adjusted to maximize air mass and the compression ratio. All containment volumes are at a pressure of 0.3 psig and 10% relative humidity, except the ice condenser which is at 100% relative humidity.
| |
| : 13. The operation of one containment spray heat exchanger (UA = 2.44x106 BTU/hr-°F, including margin for 10% tube plugging, no change from WBT-D-2751 [14]) for containment cooling and the operation of one RHR heat exchanger (UA = 1.496x106 BTU/hr-°F) for core cooling are assumed. The component cooling water heat exchanger UA was modeled as 3.17 x106 BTU/hr-°F.
| |
| : 14. The containment spray system flow start time was modeled as 234 seconds, with completion of switchover to recirculation modeled as 2719 seconds.
| |
| : 15. Containment structural heat sinks are assumed with conservatively low heat transfer rates. See Tables 4.5-1 and 4.5-2. Note that dead end compartment heat sinks were conservatively neglected.
| |
| : 16. The containment compartment volumes are 645,818 ft3 for the upper compartment, 221,074 ft3 for the lower compartment and 146,600 ft3 for the dead-ended compartment (WBT-D-2751 [14]).
| |
| : 17. The air return fan returns air at a rate of 40,000 cfm from the upper compartment to the lower compartment.
| |
| : 18. An active sump volume of 51,000 ft3 is assumed.
| |
| : 19. The RWST is assumed to be at a temperature of 105ºF.
| |
| : 20. 100.6% of 3459 MWt power is used in the calculations.
| |
| : 21. Sub-cooling of ECCS water from the RHR heat exchanger is assumed.
| |
| : 22. The decay heat curve conservatively used to calculate mass and energy releases after the termination of the enhanced steaming calculation is presented in Table 3.8-2. This decay heat curve represents the ANS 1979 + 2 model.
| |
| 4.3 STRUCTURAL HEAT REMOVAL A provision is made in the containment pressure analysis for heat storage in interior and exterior walls.
| |
| Each wall is divided into a number of nodes. For each node, a conservation of energy equation expressed in finite difference forms accounts for transient conduction into and out of the node and temperature rise of the node for the containment structural heat sinks used in the analysis. The heat sink and material property data is presented in Tables 4.5-1 and 4.5-2.
| |
| WCAP-17834-NP Revision 2
| |
| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 4-4 The heat transfer coefficient to the containment structure is based primarily on the work of Tagami [15]
| |
| and has been described in the LOTIC-1 model topical report (WCAP-8354-P-A [2], page 8-1). When applying the Tagami correlations, a conservative limit was placed on the lower compartment stagnant heat transfer coefficients. They were limited to a steam-air ratio of 1.4 according to the Tagami correlation.
| |
| The imposition of this limitation is to restrict the use of the Tagami correlation within the test range of steam-air ratios used in the derivation of the correlation.
| |
| With these assumptions, the heat removal capability of the containment is sufficient to absorb the energy releases and still keep the maximum calculated pressure below the design pressure.
| |
| 4.4 ANALYSIS RESULTS The results of the analysis show that, for a given ice mass, the calculated containment pressure is dependent upon the break location and single failure assumptions. CN-CRA-12-31 [11] contains the runs which support the ice condenser runs in the submitted WCOBRA/TRAC methodology, WCAP-17721-P
| |
| [1]. CN-CRA-12-31 [11] was subsequently updated to include the effects of the shared component cooling system and other various changes in CN-CRA-15-2 [20]. From CN-CRA-15-2 [20], the containment peak pressure results were as follows:
| |
| x DEPS Minimum Safeguards: 9.36 psig at 8959 seconds x DECL Minimum Safeguards: 8.17 psig at 5386 seconds The limiting case was the pump suction break with minimum safeguards (see Figure 4.5-1 below). Break cases with maximum safeguards (2 trains of safety injection) provide sufficient flow to the core to produce the least limiting mass and energy releases. These cases were not updated in CN-CRA-15-2 [20].
| |
| The highest calculated containment pressure was just after blowdown for the maximum safeguards cases, largely due to the compression peak. The compression peak is a separate calculation from LOTIC1, and involves a hand calculation for determining containment pressure during blowdown as lower compartment air is forced into the upper compartment during blowdown (not changing as result of the WCOBRA/TRAC methodology). The DECL minimum safeguards case also produced a low post ice bed meltout containment peak pressure. This is attributed to the fact that this particular break location and safety injection flow combination removed steam generator energy relatively early, meaning that there was relatively little SG energy contribution after the ice bed melted. The DEPS minimum safeguards case, on the other hand, produced the highest containment pressure, and it was calculated to occur after the ice bed melted. The break location produced the greatest long term steam contribution to containment, and thus the highest containment peak pressure.
| |
| FINAL DEPS Minimum Safeguards Peak Pressure: 9.36 psig at 8959 seconds Figures 4.5-2 through 4.5-6 are included for the following transients:

| | |
| WESTINGHOUSE NON-PROPRIETARY CLASS 3 4-5 Tables 4.5-3 and 4.5-4 present the containment energy accounting at key points in the containment calculation transient (end of blowdown, ice bed meltout, and peak pressure).
| |
| As described in detail in Section 3.8, the WCOBRA/TRAC DEPS minimum safeguards mass and energy releases are terminated at 20,000 seconds. In addition to providing the peak containment pressure via the 20,000 second WCOBRA/TRAC and LOTIC1 runs described above, a long term case was run to determine the equipment qualification temperature profile associated with the WCOBRA/TRAC methodology. The long term LOTIC1 run uses the DEPS minimum safeguards through 20,000 seconds, then switches to enhanced steaming calculation mass and energy releases through 400,000 seconds, and the LOTIC1 steaming calculation provides mass and energy releases for the remainder of the 30 day containment calculation.
| |
| WCAP-17721-P [1] discusses the enhanced steaming calculation. The enhanced steaming calculation
| |
| [
| |
| ]a,c Minimum safety injection flows were conservatively assumed. The results of the EQ containment LOTIC1 run are shown in Figures 4.5-7 through 4.5-10.
| |
| | |
| ==4.5 CONCLUSION==
| |
| S Based upon the information presented in this report, it has been concluded that operation with the analyzed plant conditions is acceptable at the current Watts Bar Unit 1 technical specification minimum containment ice mass of 2.26x106 lbm. Long term (30 day) containment temperature and pressure data have been provided for TVA to assess the impact on the equipment qualification (EQ) program.

| WESTINGHOUSE NON-PROPRIETARY CLASS 3 5-1 5 2.0E6 LBM INITIAL ICE MASS CONTAINMENT RESPONSE TVA requested Westinghouse to complete a LOTIC1 DEPS MIN run with an assumed ice mass of 2.00E6 lbm. This was the result of a meeting between TVA and Westinghouse on October 16, 2013 at the Westinghouse Chattanooga office. The following subsections relate to the peak containment pressure run and equipment qualification run, respectively. The mass and energy releases are the same as those in the 2.26 Mlbm LOTIC1 run, and the only change to the LOTIC1 containment model is the updated 2.0 Mlbm initial ice mass. This section presents the tabular and graphic results for both a 20,000 second peak containment pressure run and a 30 day EQ run.

| WESTINGHOUSE NON-PROPRIETARY CLASS 3 6-1 6 ADDITIONAL ICE MASS SENSTIVITY STUDIES CN-CRA-15-2 [20] includes sensitivity studies to determine the magnitude of possible future ice mass reductions at Watts Bar Unit 1. At the current technical specification analytical minimum ice mass of 2.26x106 lbm, the DEPS minimum safeguards configuration was limiting relative to containment peak pressure. Per a request from TVA, the ice mass in containment was reduced incrementally to determine the effect on containment pressure. Understanding that the DECL minimum safeguards case had the potential to become limiting at lower initial ice mass values, the DECL minimum safeguards mass and energy were also included as the ice mass approached values below 2.0x106 lbm. It is necessary to caveat these results and claim that they are not fully representative of a pedigreed analysis, and they should be used only as an indicator of potentially available reductions in the Watts Bar Unit 1 technical specification minimum ice mass. A future ice mass reduction program would need to consider possible operation of the RHR spray system, and detailed examination of results to ensure that all possible feedback effects are accounted for between the LOCA M&E and containment response (i.e., recirculation temperatures, containment backpressure assumptions, delays between ice bed meltout and initiation of containment spray recirculation).
| |
| The results indicated that reducing the assumed ice mass from the current value of 2.26 Mlbm results in ever decreasing transient times to ice bed meltout (Figure 6-1), and a correspondingly higher containment peak pressure. Results start to near the containment peak pressure limit in the 1.86 Mlbm range, and the DECL MIN case with 1.96 Mlbm does rise above 13.5 psig. Particularly noteworthy for this case is that the ice bed melts at 2368 seconds, and this is prior to the containment spray interruption during switchover to recirculation. The interruption in spray flow without the presence of ice yields a spike in containment pressure that is quickly reversed when containment spray flow is restored.

| CAW-15-4255 September 18, 2015 AFFIDAVIT COMMONWEALTH OF PENNSYLVANIA:
| |
| SS COUNTY OF BUTLER:
| |
| I, James A. Gresham, am authorized to execute this Affidavit on behalf of Westinghouse Electric Company1 LLC (Westinghouse), and that the averments of fact set forth in this Affidavit are true and correct to the best of my knowledge, information, and belief.
| |
| | |
| 2 CAW-15-4255 (1) I am Manager, Regulatory Compliance, 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 Commission's 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 Commission's 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
| |
| | |
| 3 CAW-15-4255 Westinghouse's 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.
| |
| | |
| 4 CAW-15-4255 (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, it 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 WCAP-17834-P, Revision 2, "Watts Bar Unit 1 WCOBRA/TRAC Long Term LOCA M&E and Containment Integrity Analysis" (Proprietary), dated September 2015, for submittal to the Commission, being transmitted by Tennessee Valley Authority letter and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk. The proprietary information as submitted by Westinghouse is that associated with Westinghouse's request for NRC approval of WCAP-17834, and may be used only for that purpose.
| |
| | |
| 5 CAW-15-4255 (a) This information is part of that which will enable Westinghouse to:
| |
| (i) Obtain NRC approval of WCAP-17834-P, Revision 2, "Watts Bar Unit 1 WCOBRA/TRAC Long Term LOCA M&E and Containment Integrity Analysis."
| |
| (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 design basis containment licensing analysis.
| |
| (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 calculations 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.
