==1.0      INTRODUCTION==
 
This report summarizes the Realistic Large Break Loss-of-Coolant Accident (RLBLOCA) analysis for Callaway Nuclear Plant Unit 1 (Callaway). The purpose of the RLBLOCA analysis is to support the Vendor Qualification Program (VQP) for Callaway with the Framatome GAIA fuel design. This analysis was performed in accordance with the U.S.
Nuclear Regulatory Commission (NRC)-approved S-RELAP5-based methodology described in Reference 1 with the noted exception in Section 3.3.
Callaway is a 4-loop, Westinghouse-designed Pressurized Water Reactor (PWR). The Framatome GAIA fuel design with M5Framatome cladding for Callaway consists of a 17x17 array with GAIA and Intermediate GAIA Mixing (IGM) grids, a lower High Mechanical Performance (HMP) grid and an upper HMP grid. The fuel assembly includes a MONOBLOC guide tube design, M5Framatome fuel rod design and a GRIP lower nozzle.
The fuel is standard UO2 fuel with 2, 4, 6, and 8 weight-percent Gadolinia (Gd2O3) rods included.
The analysis assumes full-power operation at a core power level of 3636 MWt (including measurement uncertainty), a maximum-allowed total peaking factor (FQ) of 2.50 (represents total peaking with an axial-dependent factor k(z) set to 1.0), a radial peaking factor (FH) of 1.65 (includes uncertainty), and up to 5% steam generator (SG) tube plugging per SG. This analysis also addresses typical operational ranges or technical specification (TS) limits (whichever is applicable) with regard to [
              ]. The analysis explicitly analyzes fresh and once-burned fuel assemblies.
The plant parameter specification for this analysis is provided in Table 4-1. The analysis uses the Fuel Swelling, Rupture, and Relocation (FSRR) model to determine if cladding rupture occurs and evaluate the consequences of FSRR on the transient response.

==SUMMARY==
OF RESULTS The UTL results providing 95/95 simultaneous coverage from this evaluation meet the 10 CFR 50.46(b) criteria with a PCT of 1561°F, a maximum local oxidation of 2.35 percent and a total core-wide oxidation of 0.028 percent. The PCT of 1561°F occurred in a once-burned 2 weight-percent Gadolinia rod with an assembly burnup of 26.2 GWd/mtU. The results of the analysis demonstrate the adequacy of the ECCS to support the 10 CFR 50.46(b) (1-3) criteria (Reference 2).

==3.0      DESCRIPTION==
OF ANALYSIS 3.1      Acceptance Criteria The purpose of the analysis is to verify the adequacy of the Callaway ECCS by demonstrating compliance with the following 10 CFR 50.46(b) criteria (Reference 2):
: 1. The calculated maximum fuel element cladding temperature shall not exceed 2200°F.
: 2. The calculated total oxidation of the cladding shall nowhere exceed 0.17 times the total cladding thickness before oxidation.
: 3. The calculated total amount of hydrogen generated from the chemical reaction of the cladding with water or steam shall not exceed 0.01 times the hypothetical amount that would be generated if all of the metal in the cladding cylinders surrounding the fuel, excluding the cladding surrounding the plenum volume, were to react.
The final two criteria, coolable geometry and long-term cooling, are treated in separate plant-specific evaluations.
Note: The original 17% value in the second acceptance criterion for MLO was based on the usage of the Baker-Just correlation. For present reviews on ECCS Evaluation Model (EM) applications, the NRC staff imposed a limitation specifying that the equivalent cladding reacted (ECR) results calculated using the Cathcart-Pawel correlation are considered acceptable in conformance with 10 CFR 50.46(b)(2) if the ECR value is less than 13% (Section 3.3.3, NRC Final Safety Evaluation (SE) for EMF-2103(P) Rev. 3).
The limitation is addressed in Table 3-1.
 
Framatome Inc.                                                                  ANP-3944NP Revision 0 Callaway Realistic Large Break LOCA Analysis with GAIA Fuel Design Licensing Report                                                                    Page 3-2 3.2        Description of LBLOCA Event A Large Break Loss-of-Coolant Accident (LBLOCA) is initiated by a postulated rupture of the Reactor Coolant System (RCS) primary piping. The most challenging break location is in the cold leg piping between the reactor coolant pump and the reactor. The plant is assumed to be operating normally at full power prior to the accident and the break is assumed to open instantaneously. A worst case single-failure is also assumed to occur during the accident. The single-failure for this analysis, as defined in the EM, is the loss of one ECCS pumped injection train without the loss of containment spray.
The LBLOCA event is typically described in three phases: blowdown, refill, and reflood.
Following the initiation of the break, the blowdown phase is characterized by a sudden depressurization from operating pressure down to the saturation pressure of the hot leg fluid. For larger cold leg breaks, an immediate flow reversal and stagnation occurs in the core due to flow out the break, which causes the fuel rods to pass through critical heat flux (CHF), usually within one second following the break. Following this initial rapid depressurization, the RCS depressurizes at a more gradual rate. Reactor trip and emergency injection signals occur when either the low pressure setpoint or the containment high-pressure setpoint are reached. However, for LBLOCA, reactor trip and scram are essentially inconsequential, as reactor shutdown is accomplished by moderator reactivity feedback. During blowdown, core cooling is supported by the natural evolution of the RCS flow pattern as driven by the break flow.
When the system pressure falls below the accumulator pressure, flow from the accumulator is injected into the cold legs ending the blowdown period and initiating the refill period. Once the system pressure falls below the respective shutoff heads of the safety injection systems and the system startup time delays are met, flow from the pumped safety injection systems is injected into the RCS. While some of the ECCS flow bypasses the core and goes directly out of the break, the downcomer and lower plenum gradually refill until the mixture in the lower head and lower plenum regions reaches the bottom of the active core and the reflood period begins. Core cooling is supported by the natural evolution of the RCS flow pattern as driven by the break flow

Towards the end of the refill period, heat transfer from the fuel rods is relatively low, steam cooling and rod-to-rod radiation being the primary mechanisms of core heat removal.
Once the lower plenum is refilled to the bottom of the fuel rod heated length, refill ends and the reflood phase begins. Substantial ECCS fluid is retained in the downcomer during refill. This provides the driving head to move coolant into the core. As the mixture level moves up the core, steam is generated and liquid is entrained, providing cooling in the upper core regions. The two-phase mixture extends into the upper plenum and some liquid may de-entrain and flow downward back into the cooler core regions. The remaining entrained liquid passes into the steam generators where it vaporizes, adding to the steam that must be discharged through the break and out of the system. The difficulty of venting steam is, in general, referred to as steam binding.
It acts to impede core reflood rates. With the initiation of reflood, a quench front starts to progress up the core. With the advancement of the quench front, the cooling in the upper regions of the core increases, eventually arresting the rise in fuel rod surface temperatures. Later the core is quenched and a pool cooling process is established that can maintain the cladding temperature near saturation, so long as the ECCS makes up for the core boil off.
3.3        Description of Analytical Models The NRC-approved RLBLOCA methodology is documented in EMF-2103(P)(A)
Realistic Large Break LOCA Methodology for Pressurized Water Reactors (Reference 1). The methodology follows the Code Scaling, Applicability and Uncertainty (CSAU) evaluation methodology (Reference 3) and the requirements of the Evaluation Model Development and Assessment Process (EMDAP) documented in Reference 4. The CSAU method outlines an approach for defining and qualifying a best-estimate thermal-hydraulic code and quantifies the uncertainties in a Loss-of-Coolant Accident (LOCA) analysis.

x      COPERNIC for computation of the initial fuel stored energy, fission gas release, and the transient fuel-cladding gap conductance.
x      S-RELAP5 for the thermal-hydraulic system calculations (includes ICECON for containment response).
The methodology (Reference 1) has been reviewed and approved by the NRC to perform LBLOCA analyses. However, a difference from the approved Reference 1 LBLOCA methodology was included in this analysis, as described below. This difference has been presented in recent NRC-approved RLBLOCA analyses (References 5 and 6).
The governing two-fluid (plus non-condensable) model with conservation equations for mass, energy, and momentum transfer is used. The reactor core is modeled in S-RELAP5 with heat generation rates determined from reactor kinetics equations (point kinetics) with reactivity feedback, and with actinide and decay heat.
 
Framatome Inc.                                                                    ANP-3944NP Revision 0 Callaway Realistic Large Break LOCA Analysis with GAIA Fuel Design Licensing Report                                                                      Page 3-5 The two-fluid formulation uses a separate set of conservation equations and constitutive relations for each phase. The effects of one phase on the other are accounted for by interfacial friction and heat and mass transfer interaction terms in the equations. The conservation equations have the same form for each phase; only the constitutive relations and physical properties differ.
The modeling of plant components is performed by following guidelines developed to ensure accurate accounting for physical dimensions and that the dominant phenomena expected during the LBLOCA event are captured. The basic building blocks for modeling are hydraulic volumes for fluid paths and heat structures for heat transfer. In addition, special purpose components exist to represent specific components such as the Reactor Coolant Pumps (RCPs) or the SG separators. All geometries are modeled at the resolution necessary to best resolve the flow field and the phenomena being modeled within practical computational limitations.
The analysis considers blockage effects due to clad swelling and rupture as well as increased heat load due to fuel relocation in the ballooned region of the cladding in the prediction of the hot fuel rod PCT.
A typical calculation using S-RELAP5 begins with the establishment of a steady-state initial condition with all loops intact. The input parameters and initial conditions for this steady-state calculation are chosen to reflect plant technical specifications or to match measured data. Additionally, the COPERNIC code provides initial conditions for the S-RELAP5 fuel models. Specific parameters are discussed in Section 3.6.
Following the establishment of an acceptable steady-state condition, the transient calculation is initiated by introducing a break into one of the loops. The evolution of the transient through blowdown, refill, and reflood is computed continuously using S-RELAP5. Containment pressure is calculated by the ICECON module within S-RELAP5.
 
Framatome Inc.                                                                  ANP-3944NP Revision 0 Callaway Realistic Large Break LOCA Analysis with GAIA Fuel Design Licensing Report                                                                    Page 3-6 A detailed assessment of the S-RELAP5 computer code was made through comparisons to experimental data. These assessments were used to develop quantitative estimates of the ability of the code to predict key physical phenomena in a PWR LBLOCA. The final step of the best-estimate methodology is to combine all the uncertainties related to the code and plant parameters and estimate values for the first three criteria of 10 CFR 50.46(b) with a probability of at least 95 percent with 95 percent confidence. The steps taken to derive the uncertainty estimate are summarized below:
: 1. Base Plant Input File Development First, base COPERNIC and S-RELAP5 input files for the plant (including the containment input file) are developed. The code input development guidelines documented in Appendix A of Reference 1 are applied to ensure that model nodalization is consistent with the model nodalization used in the code validation.
: 2. Sampled Case Development The statistical approach requires that many sampled cases be created and processed. For every set of input created, each key LOCA parameter is randomly sampled over a range established through code uncertainty assessment or expected operating limits (provided by plant technical specifications or data). Those parameters considered "key LOCA parameters" are listed in Table A-6 of Reference 1. This list includes both parameters related to LOCA phenomena, based on the PIRT provided in Reference 1, and to plant operating parameters. The uncertainty ranges associated with each of the model parameters are provided in Table A-7 of Reference 1.
: 3. Determination of Adequacy of ECCS The RLBLOCA methodology uses a non-parametric statistical approach to determine that the first three criteria of 10 CFR 50.46(b) are met with a probability higher than 95 percent with 95 percent confidence.

Framatome Inc.                                                                ANP-3944NP Revision 0 Callaway Realistic Large Break LOCA Analysis with GAIA Fuel Design Licensing Report                                                                  Page 3-8 3.6        Plant Description The plant analyzed is the Callaway Nuclear Plant Unit 1, Westinghouse-designed PWR, which has four loops, each with a hot leg, a U-tube steam generator, and a cold leg with an RCP. The Reactor Coolant System (RCS) includes one pressurizer connected to a hot leg. The ECCS provides injection to each of the four loops via the centrifugal charging/high head safety injection (HHSI) system, SI/intermediate head safety injection (IHSI) system, residual heat removal (RHR)/low head safety injection (LHSI) system, and accumulators. The RLBLOCA transients are of sufficiently short duration that the switchover to sump cooling water for ECCS pumped injection does not need to be considered.
The RCS, reactor vessel, pressurizer, and ECCS are explicitly modeled in the S-RELAP5 model. For the LOCA analysis, IHSI and HHSI are modeled as a combined system and identified as HHSI. For each RCS loop, the ECCS model includes an injection connection to the cold leg for the accumulator, another connection for HHSI, and another connection for LHSI. The ECCS injection connections to the cold leg pipes are downstream of the RCP discharge. The ECCS pumped injection is modeled as a table of flow versus backpressure. Also modeled is the secondary-side steam generator that is instantaneously isolated (closed main steam isolation valve and feedwater trip) at the time of the break. The primary and secondary coolant systems for Callaway were nodalized consistent with code input guidelines in Appendix A of Reference 1. System nodalization details are shown in Figure 3-1 through Figure 3-3.

However, the analysis includes considerations for the mixed core scenario.        [
                                  ]
As described in Section 3.3, many parameters associated with LBLOCA phenomenological uncertainties and plant operation ranges are sampled. Values for process or operational parameters, including ranges of sampled process parameters, and fuel design parameters used in this analysis are given in Table 4-1. Table 4-2 presents a summary of the uncertainties used in the analysis. Two parameters (refueling water storage tank temperature and diesel start time) are set at conservative bounding values for all calculations. The passive heat sinks and material properties used in the containment input model are provided in Table 4-3.

The fraction of total hydrogen generated was not directly calculated; however, it is conservatively bounded by the calculated total core wide percent oxidation, which is well below the 1 percent limit.
A summary of the major input parameters for the demonstration case is provided in Table 4-5. The sequence of event times for the demonstration case is provided in Table 4-6. The heat transfer parameter ranges for the demonstration case are provided in Table 4-7. Table 4-8    [

Figure 4-1 shows linear scatter plots of the key parameters sampled for all cases.
These figures illustrate the parameter ranges used in the analysis. Visual examination of the linear scatter plots demonstrates that the spread and coverage of all of the values used is appropriate and within the uncertainty ranges listed in Table 4-2. Appendix A provides a listing of all the sampled input values for each case. Key results such as the PCT and event timings are also listed for the case set.
Figure 4-2 and Figure 4-3 show PCT scatter plots versus the time of PCT and versus break size, respectively. The scatter plots for the maximum local oxidation and total core-wide oxidation are shown in Figure 4-4 and Figure 4-5, respectively.
Figure 4-2 shows about 26% of cases have PCT during the blowdown phase (PCT time less than ~30 seconds). The next cluster of PCTs occurs during the early to late reflood period. Blowdown PCT cases are dominated by rapid RCS depressurization and stored energy content. Reflood PCT cases are dominated by decay heat removal capacity. In general, plants with high pressure accumulators inject early in the transient when the break flow is still high. The high pressure and high break flow drive some of this fluid to bypass the core, retarding the progression of the core reflood. This results in cases with PCTs in the reflood phase of the transient.
The high PCT cases in the upper part of Figure 4-2 are mainly influenced by the area of the break. This is demonstrated in Figure 4-3 which shows a general increasing trend in PCT with break size. From all sampled parameters, the break size is a dominant effect on PCT because of its influence on the rate of primary depressurization.

Since the MLO includes the pre-transient oxidation, the MLO is not only a function of cladding temperature but also of time in cycle (burnup).    [
                          ]  The CWO also shows a strong correlation to PCT as demonstrated in Figure 4-5, as higher PCT cases would have higher oxidation throughout the core.
The demonstration case is a reflood peak case with a PCT timing of 76 seconds.
Figure 4-6 through Figure 4-17 show key parameters from the S-RELAP5 calculations for the demonstration case. The transient progression for the demonstration case follows that described in Section 3.2.
