South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 5.9 Ex-Vessel Downstream Effects Components and Systems downstream of the sump strainers were evaluated to assess the effects of debris-laden fluid on the ability of the ECCS and CSS components and systems to perform their post-LOCA, design basis functions (88; 89; 90).
The evaluations were developed in accordance with WCAP-16406-P (91) and the accompanying NRC SER (92). No exceptions were taken to the WCAP-16406-P methodology. Note that the WCAP methodology is a deterministic approach that evaluates ex-vessel downstream effects in a conservative and bounding manner.
5.9.1 Pump, Valve, Component Wear Concerns with wear due to ingested debris were evaluated for pumps, valves, heat exchangers, orifices, and spray nozzles within the ECC and CS systems.
ECCS and CS Pump Wear Evaluation The HHSI, LHSI, and CS pumps were evaluated in accordance with the methodology established in WCAP-16406-P. The pumps were evaluated based on three aspects of operability: hydraulic performance, mechanical performance (vibration) and mechanical shaft seal assembly performance.
The WCAP evaluation concluded that no effect on hydraulic performance is expected.
The HHSI, LHSI, and CS pumps are multi-stage and were evaluated for mechanical (vibration) performance. In accord with WCAP-16406-P, the abrasive, erosive, and Archard wear models were used to calculate the amount of wear (mils) on the suction and discharge sides of each stage of the pumps.
The evaluation showed that the combined stiffness of the suction and discharge wear rings after being asymmetrically worn by free flowing abrasive wear and Archard wear, respectively, is less than the stiffness provided by both the suction and discharge wear rings being symmetrically worn to 2 times the design clearances for the HHSI, LHSI, and CS pumps. Therefore, the HHSI, LHSI, and CS pumps pass the mechanical (vibrations) evaluation and are acceptable The mechanical shaft seal assembly performance evaluation suggested replacing the LHSI, HHSI and CS pumps' carbon/graphite packing assemblies with a more wear resistant material. However, STP has an Engineered Safety Feature (ESF) atmospheric filtration system for the building where the pumps are located. Therefore the current the carbon/graphite seal bushings are acceptable as-is.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GS1191-V03 Revision 2 Valve Wear Evaluation Valve evaluations were performed in accordance with the criteria in WCAP-16406-P. The evaluations determined that the wear impact was not critical and in no need of further evaluation.
Heat Exchanger Wear Evaluation:
Plant heat exchangers were evaluated in accordance with WCAP-16406-P. Tube failure for heat exchangers will occur when the resultant wall thickness after erosion is less than the required wall thickness to retain internal and external pressures. The evaluation concluded that the minimum wall thickness required to retain both internal and external pressures is less than the resultant wall thickness after erosion. Therefore, the heat exchangers are not expected to fail.
Orifice Wear Evaluation ECC and CS System orifices were evaluated in accordance with the methodology established in WCAP-16406-P. WCAP-16406-P states that if the orifice inside diameter is changed by less than 3% due to erosive wear, the system performance may be considered negligible. The evaluation shows that the inside diameters of all orifices change by less than 3% and is therefore acceptable.
Spray Nozzle Wear Evaluation The CS system spray nozzles were evaluated in accordance with the methodology established in WCAP-16406-P. WCAP-16406-P concluded that un-acceptable wear is when the wear of the nozzle results in an expected system flow increase greater than 10%. The STP evaluation concludes that CSS flow is changed by less than 2% and is therefore acceptable.
5.9.2 System and Component Clogging/Blockage ECC and CS system and component clogging/blockage were evaluated in accordance with the methodology established in WCAP-16406-P. The evaluation showed that the following ECCS and CSS components can accommodate penetrated particles without clogging, restricting or blocking flow:

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 5.10 In-Vessel Downstream Effects In-vessel effects include issues with impaired heat transfer on the fuel rods due to debris buildup on the cladding, as well as core blockage due to debris that penetrated through the strainer. Also, in January 2012, the NRC requested that the generic boron precipitation issue be considered as part of the overall scope of GSI-191. Boron precipitation is discussed in more detail in Section 5.11.
5.10.1 Fuel Rod Debris Deposition (LOCADM)
When debris laden water is circulated through the core, it is possible that some of that debris may be deposited on the fuel rods resulting in a layer of debris that reduces heat transfer. This buildup process is illustrated in Figure 5.10.1.
The issue of impaired heat transfer due to debris deposition on the fuel rods has been evaluated by the PWROG in WCAP-16793-NP, and a tool called LOCADM was developed to calculate the maximum thickness of debris and maximum temperature of the cladding based on plant-specific inputs (63). The acceptance criteria for this evaluation are that the peak cladding temperature must be less than 800 °F, and the total deposition thickness must be less than 50 mils. Based on an STP-specific evaluation using the conservative WCAP-16793-NP methodology, the maximum cladding temperature was calculated to be 368.90 "F, and the maximum deposition thickness was calculated to be 13.64 mils (93). These values are well within the acceptance criteria. Therefore, since the deterministic evaluation for STP shows that there are no issues with debris deposition on the fuel rods, this issue was not explicitly evaluated in CASA Grande.

Medium and large breaks are similar in terms of core blockage (the main difference being the total SI flow rate as shown in Section 2.2.8). However, for a small break, the break size is small enough to allow the RCS to fill with water and enable natural circulation. This would be true for breaks on either the hot or cold leg side. For medium and large breaks, however, the flow path through the core is highly dependent on the location of the break (cold leg or hot leg side breaks) and the injection path (cold leg or hot leg injection).

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Following a LOCA at STP, water would initially be injected from the RWST to three out of four of the cold legs (see Figure 5.10.2). Since the water from the RWST is free of debris, there would be no potential for core clogging during this phase. After the RWST has been drained (30-44 min for an LBLOCA, 44-79 min for an MBLOCA, and up to several hours for an SBLOCA (5)), the SI and CS pumps would be realigned to take suction from the ECCS sumps. At this point, some fine debris could start to pass through the strainers. Due to potential issues with boron precipitation, two of the three trains would be realigned from cold leg injection to hot leg injection approximately 6.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> after the start of the accident 26 (see Assumption 1.j). The third train would remain aligned on cold leg injection. In the unlikely event that only one train is operating, the realignment to hot leg injection would not occur since the emergency operating procedure (EOP) requires that one train be left on cold leg injection (36).

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Medium and Large Hot Leg Breaks For a medium or large hot leg break, the SI flow would initially be injected in the cold legs forcing the flow to pass through the core and then spill out the break. After the start of recirculation, but before hot leg switchover (HLSO), debris that penetrates the strainer would transport with the flow and accumulate in the core. The head loss due to the debris would result in a compensating rise in the steam generator water level. Eventually, given sufficient head loss, a portion of the SI flow could pass over the steam generator tubes reducing the flow through the core. This scenario is illustrated in Figure 5.10.3.
Driving Head Hot Leg
)~~~I L-eg-Hot Leg Figure 5.10.3 - Large or medium hot leg break during cold leg injection with partial core blockage There are two potential concerns that have been raised with the hot leg break/cold leg injection scenario: 1) if flow starts spilling over the steam generator tubes, it may cause a siphon to form that would suck all of the SI flow over the tubes and directly out the break (94), and 2) core blockage may be large enough to prevent sufficient decay heat removal from entering the bottom of the core and the remaining SI flow may preferentially spill over the steam generator on the broken loop where it could pass directly out the break.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 A siphon is essentially an inverted U-shaped tube where the weight of the water on the discharge side of the tube creates a low pressure region at the top of the tube that sucks water up from the suction side of the tube. However, if the pressure at the top of the tube falls below the vapor pressure, the siphon will break. At standard conditions, the maximum possible height of a siphon (neglecting frictional losses) is approximately 33 ft. In general, since the temperature (and the corresponding vapor pressure) in the steam generator tubes would be significantly higher than standard conditions, the siphon would break at an elevation less than 33 ft. Elevated containment pressure could increase the maximum height of a siphon, but elevated pressure generally trends with elevated temperature, and the containment pressure drops quickly during the RWST injection phase (5). At STP, the lowest steam generator tubes are over 40 ft above the bottom of the hot legs (95). Therefore, flow over the steam generator tubes would not result in a siphon effect. This conclusion is further supported by the results of thermal-hydraulic simulations (29). Thermal-hydraulic simulations also showed that water would not preferentially flow over the steam generator tubes on the broken loop (29)27. This is discussed in more detail below.
After switchover to hot leg injection, two trains of SI flow would be injected in two of the hot legs, while the third train of SI flow would continue to be injected in one of the cold legs. The water injected through the cold leg would continue flowing through the same path (through the core and out the break and/or over the steam generator tubes if partial or full blockage has occurred). The water injected in the hot legs would pass through the upper plenum providing coolant at the top of the core, and exit through the broken loop. This is illustrated in Figure 5.10.4. Note that the simultaneous cold leg injection flow is not shown in this figure, but would tend to enhance mixing and the total flow through the core (unless the bottom of the core was fully blocked by debris during the cold leg injection phase).
27 Note that preliminary results from additional thermal-hydraulic modeling have indicated that under very specific conditions, it may be possible for a siphon to occur. However, the siphon effects were temporary and did not result in unacceptable peak cladding temperatures.

-A Figure 5.10.4 - Large or medium hot leg break during hot leg injection Although it is possible that debris could continue to penetrate the strainer later in the event (after HLSO), it is not likely that the debris would cause any significant blockage issues during hot leg injection (see Assumption 10.a).
Medium and LarRe Cold LeR Breaks For a medium or large cold leg break, the SI flow would initially be injected in the cold legs, and the majority of the flow would bypass the core spilling directly out the break. However, a portion of the injected water would flow into the core to makeup the water lost due to boil-off. The debris that penetrates the strainer after the start of recirculation would transport with the flow, and a portion of the debris could accumulate in the core. Unlike the hot leg break scenario, however, the head loss due to the debris would result in a decrease in the core water level rather a rise in the steam generator water level. Eventually, given sufficient head loss, a portion of the core could be uncovered resulting in potential core melt. The cold leg break during cold leg injection scenario is illustrated in Figure 5.10.5.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Figure 5.10.5 - Large or medium cold leg break during cold leg injection with partial core blockage There are two potential concerns that have been raised with the cold leg break/cold leg injection scenario: 1) core blockage may be large enough that the water level cannot be maintained above the top of the core, and 2) debris buildup at the bottom of the core may prevent mixing with the lower plenum volume resulting in a more rapid onset of boron precipitation. The core blockage issue is discussed in more detail in the remainder of Section 5.10, and the boron precipitation issue is addressed in Section 5.11.
After switchover to hot leg injection, two trains of SI flow would be injected in two of the hot legs, while the third train of SI flow would continue to be injected in one of the cold legs. The water injected through the cold leg would flow directly out the break. The water injected in the hot legs would pass from the upper plenum, down through core and lower plenum, and exit through the broken loop. This is illustrated in Figure 5.10.6. Note that the simultaneous cold leg injection flow is not shown in this figure, but would have minimal effect since it would bypass the core and spill directly out the break.

Although it is possible that debris could continue to penetrate the strainer later in the event (after HLSO), it is not likely that the debris would cause any significant blockage issues during hot leg injection (see Assumption 10.a).
Small Hot and Cold Lee Breaks For a small break, the capacity of the SI pumps is significantly higher than the flow that would be spilling out the break. Early in the event when the decay heat is still relatively high, the required flow to cool the core can be higher than the SI flow rate. In this scenario, however, the RCS would be mostly full of water and natural circulation would circulate sufficient flow to cool the core. This is illustrated in Figure 5.10.7.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Figure 5.10.7 - Small hot leg break during cold leg injection Thermal-Hydraulic Simulations A series of RELAPS simulations were run to investigate the effects of full blockage at the bottom of the core following the start of recirculation to determine which scenarios would proceed to core damage (29). The six scenarios that were modeled included small (2-inch), medium (6-inch), and large (DEGB) breaks on both the hot leg and cold leg piping. The results of the simulations showed that if the core is fully blocked for a hot leg break (of any size), the water would spill over the steam generator tubes and pass through the upper plenum before spilling out the break. The simulations showed that this alternate flow path is sufficient to remove decay heat from the core and prevent the peak cladding temperature from exceeding 800 °F (29). Similarly, for the small (2-inch) cold leg break scenario, the break is small enough that the SI flow would fill the RCS above the top of the steam generator tubes allowing the SI flow to reach the core through the upper plenum, and prevent subsequent core damage (29). Out of the six scenarios that were run, only the medium and large cold leg breaks proceeded to core damage following the simulated blockage at the bottom of the core.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 5.10.3 Decay Heat Boil-Off Flow Rate For cold leg breaks during cold leg injection, the portion of the SI flow entering the lower plenum and core depends on the boil-off rate. The boil-off rate can be calculated based on the decay heat curve. As shown in Section 2.2.30, the 1979 ANS plus 2 sigma uncertainty heat generation rate was used. The actual flow into the core required to remove the decay heat is dependent on the temperature of water entering the core, the saturation temperature (i.e., the RCS pressure), and the decay heat curve. All three of these parameters can change significantly over time. The time-dependence of the decay heat is defined by the 1979 ANS curve, and the time-dependence of the inlet temperature and RCS pressure is dependent on the break size, pool temperature, etc.
The boil-off flow rate can be calculated using the following equations:
Qboil =
Equation 97 Pin' (AHtemp + AHvap)
AHtemp = HIsat -
Hin Equation 98 AHvap = Hv,sat - Hl,sat Equation 99 where:
Oboi, = Boil-off flow rate Pcore = Power introduced from the core Pin = Density of SI flow as a function of the inlet temperature AHtemp = Change in enthalpy required to raise the temperature to saturation AHvap = Change in enthalpy required to change phases from liquid to vapor Hin = Enthalpy of SI flow entering the vessel as a function of the inlet temperature Hi,sat = Saturated liquid enthalpy as a function of the RCS pressure Hv,sat = Saturated vapor enthalpy as a function of the RCS pressure The enthalpies and inlet density were determined based on standard water properties assuming that the RCS pressure is 14.7 psia, and the SI flow is saturated liquid at 212 °F (see Assumption 10.b). These pressure and temperature values were conservatively used for all break scenarios and treated as constants over the duration of the event. Table 5.10.1 and Figure 5.10.8 show the calculated boil-off rate as a function of time.

A fraction of the debris that penetrates the strainer can be split off to the spray pumps, and a fraction of the debris transported with the SI flow can bypass the core and spill directly out the break (see Section 5.8).

Based on the thermal-hydraulic modeling, which showed that full blockage at the bottom of the core would not result in core damage for hot leg breaks, the acceptance criterion was set to essentially an infinite fiber quantity.
For cold leg breaks, an acceptance criterion of 15 g/FA was used based on the conservative results of testing by the PWROG (see Section 2.2.31).
Note that the core blockage acceptance criteria are bounded by the boron precipitation acceptance criteria (see Section 5.11.2).
5.11 Boron Precipitation Boric acid precipitation can occur in cases where there is boiling in the core. The water entering the core has a given boron concentration. As the water boils, the boron becomes more concentrated and eventually can reach the solubility limit and begin to precipitate. Figure 5.11.1 shows an example of boron precipitation during a test.

Significant boron precipitation is most likely to occur for a medium or large cold leg break during cold leg injection. In this scenario the water in the core would be boiling and the net flow entering the core would be equivalent to the decay heat boil-off rate (see Section 5.10). To prevent boron precipitation in these scenarios, the SI flow is switched from cold leg injection to hot leg injection. The required switchover timing is dependent on the concentration of boron in the RCS/RWST/accumulators, the decay heat level, and natural mixing processes within the reactor vessel based on temperature and/or density gradients. The generic methodology used for evaluating boron precipitation has been questioned by the NRC (96), and the PWROG is currently addressing these concerns to determine whether the physical phenomena associated with temperature or density driven mixing have been appropriately modeled. The reason that boron precipitation was included in the overall GSI-191 issue, however, is that even if the physical phenomena for temperature and density driven mixing was appropriately modeled previously, the formation of a debris bed at the bottom of the core may interrupt these natural mixing processes and accelerate the onset of boron precipitation.
Based on an STP-specific evaluation using the old methodology, it was determined that boron precipitation would not occur until at least 7.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> after the initiation of the event (97). For the risk-informed GSI-191 evaluation, it was assumed that the previous methodology was appropriate, and that boron precipitation would not occur unless a significant debris bed builds up on the bottom of the core that could disrupt the natural mixing processes that were credited (see Assumption 11.a).

5.11.2 Acceptance Criteria: Debris Loads As discussed in Assumption 11.d, boron precipitation is not considered to be an issue for hot leg breaks.
For medium and large cold leg breaks, the acceptance criterion for boron precipitation was assumed to be 7.5 g/FA of fiber debris on the core (see Assumption 11.b).
5.12 Parametric Evaluations One of the greater values that accrue from building a comprehensive system analysis platform like CASA Grande lies in the ability to conduct parameter studies and comparative examinations to help prioritize plant operation strategies, risk mitigation investment, and research and development activities.
Within this version of the analysis, it was not possible to run an extensive suite of parametric evaluations. However, one scenario of particular interest was a quantitative risk-benefit assessment of the strainer replacement project at STP.
Strainer replacement was performed at STP Unit 1 in October 2006 and Unit 2 in April 2007 (98). The original strainers were a flat-plate box design as shown in Figure 5.12.1. The strainer area was only 155.4 ft2 per train (99). The ECCS suction strainers were upgraded to a total of 1,818.5 ft2 per strainer using a PCI SureFlow T
M design (see Section 2.2.22). The strainer upgrade increased the capacity for fibrous debris loading per unit area by almost a factor of 12, but may have concurrently increased the vulnerability to debris penetration for small debris loads that do not fully cover the surface of the new design.28 28 There may be some other variations between the strainers that could affect some aspects of the analysis, but the most important difference is the strainer area.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GS1191-V03 Revision 2 Figure 5.12.1 - STP ECCS strainer prior to upgrade The test-validated filtration and penetration model implemented in CASA now enables a comparison of competing effects like enhanced debris penetration from low debris areal densities on a large strainer compared to higher pressure drops caused by large debris areal densities on a small strainer. To quantify the net benefit of strainer replacement, the CASA analysis was repeated under the same set of parameter assumptions and conservative uncertainty factors for chemical effects and pressure-drop prediction, by simply changing the clean strainer surface area.
Results for LBLOCA conditional failure probabilities are presented in Table 5.12.1 to compare the previous plant condition to the present plant condition. Note that these results represent comparative trends between self-consistent calculations where strainer area was the only difference in input. As described in the revision history log, there were several changes to the input parameters and source code for CASA, which resulted in new conditional failure probabilities for the current strainer configuration. Therefore, the results in Table 5.12.1 should only be used as a qualitative indication of the effects of the strainer replacement. The final results for pump-state failure probabilities used for risk-region assessment are presented in Section 6. Replacement of the ECCS strainers resulted in a minimum reduction factor in conditional failure probability for LBLOCA of approximately 100 (see highlighted cell).
More significantly, strainer replacement eliminated vulnerabilities to small and medium break events that trigger a large fraction of failure events when analyzed with the old strainer area. No failures are recorded for small and medium-break scenarios using the current ECCS strainer specifications.
Page 229 of 248
South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Trends in Table 5.12.1 also confirm that the models implemented in CASA for debris filtration/penetration and circulation through the plant are behaving intuitively. For example, small strainers will load rapidly and limit debris penetration primarily to the shedding phase of debris-bed behavior. This is indicated by the absence of boron-related core-fiber load failures. All failure modes for the smaller strainers are related to higher head loss that is induced both by thicker beds and by much higher flow velocities.
The reductions in conditional failure probability shown in Table 5.12.1 cannot be equated directly with the same reduction in ACDF risk without a complementary RISKMANTM analysis, but preliminary indications are that significant risk reductions were achieved through the strainer replacement campaign. These risk reductions are likely to have been significant enough to move STP from Regulatory Guide 1.174 Region II down to the current quantified status in Region III (73). Thus, proactive compliance with NRC regulation through strainer upgrade achieved an important and quantifiable improvement in plant safety. Note that the core blockage failures all have a zero failure probability. This is due to the fact that the core blockage acceptance criteria are bounded by the boron precipitation acceptance criteria. It doesn't mean that it is not possible for core blockage to occur.

Results One of the primary functions served by CASA Grande in the risk-informed resolution process is quantifying conditional failure probabilities related to GSI-191 phenomena for various states of plant operability. Failure probabilities are passed to the plant-wide PRA, which determines the incremental risk associated with GSI-191 failure modes. In this role, CASA serves very much like an elaborate fault tree that informs top-event branch fractions that are built-in to the event tree. Three new top events have been added to the PRA to accommodate composite GSI-191 failure processes: (1) failure at the sump strainer, (2) boron precipitation in the core, and (3) blockage of the core.
CASA compiles the three composite failure probabilities needed for the PRA by testing the outcome of every postulated break scenario against seven performance thresholds: (1) strainer AP __ NPSH margin, (2) strainer AP _> structural margin, (3) strainer void fraction > 0.02, (4) core fiber load > cold leg break fiber limit for boron precipitation, (5) core fiber load > hot leg break fiber limit for boron precipitation, (6) core fiber load > cold leg break fiber limit for flow blockage, and (7) core fiber load > hot leg break fiber limit for flow blockage. Failure Modes 1-3 are counted as failures if any single operable strainer exceeds the thresholds at any time during the 36-hr calculation. Failure Modes 4-7 are assessed against the accumulated fiber penetration from all operable strainers, and they must exceed the threshold before switchover to hot leg injection to be counted as failures. For the present quantification, thresholds for modes 5-7 were set infinitely high so that only exceedance of the cold leg break boron precipitation loading (Failure Mode 4) was recorded as failure. This approach is reasonable because the threshold for Failure Mode 4 is substantially lower than the others, and all depend on the same internal flow distribution and fiber accumulation processes.
In the present quantification, violation of any of the seven performance thresholds is counted as an independent failure. Thus, it is possible that a single scenario can contribute both a strainer-related failure tally, and a core fiber load failure tally. After a suite of scenarios is evaluated, the sum of probability weights for failed scenarios within each LOCA category is divided by the sum of probability weights for all scenarios within each LOCA category to generate the conditional failure probabilities needed for the PRA. Table 6.1 reports the mean conditional failure probability associated with each composite failure mode for each of five pump state combinations. No failures were recorded for small or medium-break events, and later discussion will explain that only the higher range of large-break events contributed to failure.

Table 6.1 results can be interpreted in the following ways: Design basis accident response with three trains operable (Case 1) is estimated to incur a total failure probability of 0.47% given that an LBLOCA occurs (approximately 5 failures in every 1,000 large-break events). If only one train is operable (Case 43), this estimate increases to 1.9% (approximately 2 failures in every 100 large-break events). The primary reason for the increase is the additional head loss incurred at the single strainer by collecting all of the debris that is distributed in proportion to flow across three strainers under Case 1. Conversely, failures incurred by exceeding the boron fiber load are reduced (compare first and last columns of second row), because less cumulative fiber is penetrating the single, highly loaded strainer. Blockage failure is reported as zero probability because the thresholds were set very high, partly to avoid double counting blockage failures for events that first exceed the bounding low value for fiber load thresholds related to boron precipitation.
Conditional failure probabilities reported in Table 6.1 are described as "mean" or "expected" values because 15 point estimates associated with independent samples of the NUREG-1829 break frequency envelope have been averaged for use in the PRA. The following discussion explains the origin and the mechanics of this averaging process.
Recall that the NUREG-1829 tables assign confidence-levels to estimates of annual occurrence frequency as a function of break size. This assignment of confidence level defines an envelope of epistemic uncertainty that was fit using bounded Johnson probability density functions at each discrete break size for which percentiles of confidence were tabulated. The purpose of these fits was to enable interpolation of the confidence bands at any intermediate break size of interest. The relationship defined by NUREG-1829 between annual occurrence frequency (events per year) and break size is presented in terms of complementary cumulative distribution functions (CCDFs). This format implies that underlying probability density functions (PDFs) have been integrated, and it is important to 31 Case 1 = Full three-train operation; Case 9 = Dual LHSI pump failures; Case 22 = Single train failure; Case 26 =
Single train failure with an additional LHSI pump failure; Case 43 = Dual train failure.
32 The boron precipitation evaluation for Case 43 assumes that hot leg switchover will occur at approximately 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. However, if only one train is operating, it is likely that hot leg switchover would not occur and medium and large cold leg breaks are likely to have boron precipitation. This is not reflected in the value specified for Case 43, but is explicitly evaluated in the PRA model.
33 The residual sampling precision is shown for each total as the ratio of standard deviation to the mean.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 consider the form of the PDFs before selecting an interpolation scheme that will be applied to the CCDFs. Conversely, any presumption about interpolation of the CCDF has implications for the implied form of the PDF.
A PDF defined for break size must define the probability per unit of size that a break occurs within the interval between the discrete sizes tabulated in NUREG-1829. Without knowing the details of how fracture mechanics processes were treated during compilation of the NUREG-1829 table, it is difficult to defend any assumption other than uniform probability density between the tabulated discrete sizes.
Uniform probability density means that any break size within the interval is equally likely. Uniform (constant) break-size probability density between two CCDF values is easily calculated as the positive difference between the complementary cumulative annual frequencies divided by the positive range of size across the interval divided by the total annual exceedance frequency for the smallest break size. The integral of a constant PDF needed to form a CCDF is a straight line, and this implies that linear-linear interpolation of the NUREG-1829 table is the only treatment consistent with the assumption of constant underlying probability density. Alternative treatments may be justified, but insufficient evidence was available to defend them for use in this quantification. Formal mathematical proof can be provided to support this discussion.
Linear-linear interpolation of the NUREG-1829 table values leads to an interesting visual effect when plotted on log-log axes. As shown in Figure 6.1, the piecewise linear CCDF appears as a periodically looping curve on a logarithmic scale. The practical effect of linear interpolation is that break frequency (and probability) remains conservatively high across most of each size range, and only descends to match the tabulated CCDF values near the end of each interval. Figure 6.1 illustrates the extreme endpoints of the bounded Johnson fits (solid lines) and several typical random samples of the break-frequency profile that were used in this assessment (dashed lines).
Non-uniform stratified random sampling of break-frequency profiles from the Johnson PDF envelope are performed in exactly the same manner as for all other random variables. Non-uniform probability bins are predefined based on the desired number of samples and on the direction of presumed conservatism, then random percentiles are chosen from within each bin to represent, or "carry", the associated probability weights. For this study, 15 independent random samples were extracted from the Johnson envelope for each plant state, with an emphasis on upper percentiles of the break-frequency uncertainty envelope. Given a sample of 15 percentiles, the Johnson fits are then inverted to find the corresponding annual frequencies. It is important to note that all Johnson fits are perfectly correlated by using the same fixed values of the sampled percentiles. Finally, the set of annual frequencies from each Johnson fit is linearly interpolated to create the break-frequency profiles shown as the dashed lines in Figure 6.1.
Each break-frequency profile is fully analyzed in CASA using a set of 20 batch replicates containing approximately 2,250 break scenarios each to obtain a point estimate of failure probability for the Page 234 of 248
South Texas Project Risk-informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 composite modes. (Residual sampling precision of -5% between the 20 replicates is typical of this scenario sampling size. Better precision can be obtained using larger sample sizes or more replicates as time permits.) Probability weights from stratified sampling of the Johnson envelope are then used to form the weighted conditional means reported in Table 6.1 above.

Table 6.2 below reports the 15 point estimates and their associated probability weights generated for the total failure probability under plant operability Case 43 (single train operable). The weighted mean is formed simply by multiplying each point estimate by its probability weight and adding the products.
Similar distributions were formed for all composite failure modes and for all plant operability states, but only the weighted means are presented in Table 6.1 above.

This distribution reflects only the uncertainty inherent to the estimation of annual break frequency. All other random variability, including ranges on physical phenomena and decision criteria, has been integrated into each point estimate. As shown in Table 6.2 and Figure 6.2, typical variation in failure probability estimates spans a factor of 4 between the minimum and maximum values (0.051/0.012 = 4.3). This variation is caused solely by the shape of the randomly selected break-frequency profiles, which dictates the relative proportion of break frequency by size.
It is important to reemphasize that CASA Grande never makes any direct use of the annual break frequency as a time-rate quantity. All analyses proceed conditioned on the assumption that a break has already occurred. Sample profiles taken from the break-frequency envelope then describe how to partition the relative occurrence of breaks by size. CASA further redistributes the relative probability by size across weld types in order to map the cumulative probability of a break as a function of size to discrete locations in the plant (see Section 5.3).

That is why it is important for CASA and the PRA to use exactly the same representation of the Johnson PDF fits. The Johnson fits are evaluated analytically in CASA to generate a table of empirical PDFs that are manually passed to RISKMAN for repeated sampling in the risk quantification. While RISKMAN may generate thousands of samples from the annual frequency uncertainty envelope, CASA is not computationally efficient enough to match that resolution. It is much more important to place available sampling resolution on the physical variables that drive the outcome of each break scenario, and to rely on non-uniform sampling for generating unbiased estimates of the mean failure probability. At the beginning of this quantification, it was presumed that failure distributions like that shown in Figure 6.2 would be sampled by the PRA to generate distributions of incremental risk attributable to GSI-191 phenomena. Under this assumption, additional sampling resolution was placed in the high-percentile tails of the Johnson distributions so that the distribution of failure probability associated with the highest annual frequencies would be the most accurate. Practical experience with the PRA sampling process now emphasizes the mean failure estimate, so CASA sampling strategies may be changed in the future to provide more accurate estimates of mean failure probability.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 One other key piece of information that is passed from CASA back to the PRA is the conditional split fraction for cold leg breaks in each LOCA category. Recall that CASA distributes total break-size probability for a single NUREG-1829 profile across all welds in containment. This process uses the hybrid weighting scheme (described in Section 5.3) to account for the contributions of small breaks on large pipes to the small and medium LOCA categories. Each break scenario sampled from this process carries a specific size and location and a fractional weight of the total break-size probability. Before any other physical parameters are considered, the distribution of probability weight can be partitioned into hot leg and cold leg events and by LOCA size.
Table 6.3 itemizes cold leg split fractions obtained for the 15 break frequency profiles associated with Case 43. These values were obtained by dividing the sum of probability weights for cold leg breaks in each LOCA category by the sum of probability weights for all breaks in the LOCA category. Hot leg split fractions are simply the complement of any single entry in the table. Recall that 20 replicates of 2,250 scenarios are evaluated for each of 15 break frequency profiles for a total of 20 x 2,250 x 15 = 675,000 scenarios per plant state. Cold leg split fractions are mildly dependent on the break frequency profile shape (15 samples), but they are independent of plant operability state (5 states) and scenario replicates (20 replicates) for any given sample of the break-frequency envelope. It is interesting to note that the proportion of large cold leg breaks is substantially smaller than the 50% proportion assumed in the preliminary quantification in December 2011.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 The fact that no small or medium break events have been recorded as failure for any scenario evaluated in this quantification is a strong indication that there is a minimum size break below which insufficient debris can be formed to challenge the safety systems.
More detailed information regarding weld location and debris compositions that lead to failure can be extracted from the CASA analysis to help prioritize risk mitigation strategies such as local insulation replacement, additional ISI requirements on risk-dominant welds, plant cleanliness actions, etc.

Conclusions The CASA Grande program provides an integrated framework for comprehensively evaluating GSI-191 phenomena based on plant-specific inputs. The STP evaluation showed that the likelihood of failure associated with GSI-191 for the current plant conditions is very low. Based on the inputs and models used, long-term core cooling was not predicted to fail for any of the small or medium break LOCAs evaluated, and was predicted to fail for only a small fraction of the large break LOCAs. It should be noted that this evaluation included significant conservatisms to address the uncertainties associated with chemical effects.
Some significant plant modifications have been made previously to address GSI-191 concerns-most notably the ECCS strainer replacement project in 2006 and 2007. The STP strainer upgrade was achieved at a cost on the order of $6.3M (98). This modification resulted in a safety improvement where the number of cases predicted to fail decrease by a factor on the order of 100 times. This reduction very possibly resulted in the desired shift from Regulatory Guide 1.174 Region II to Region III (73). Safety improvement actions exceeding a factor of 100 are difficult to find in any mature engineered system, and the next proposed GSI-191-related major upgrade involves insulation replacement. The cost and radiological exposure estimates for replacement of insulation are significant, approaching tens of millions of dollars and hundreds of person-Rem per unit, depending on the scope of the modifications.
These comparisons suggest that STP has achieved a condition of decreasing marginal safety benefit where the costs of dramatic design changes may exceed the net risk-benefit that would be gained. With the availability of the coupled CASA Grande/RISKMAN analysis framework, dominant residual risk contributors can now be managed in a fiscally sound manner to progressively and continually improve plant safety in a quantifiable risk-management context.

South Texas Project Risk-Informed GSI-191 Evaluation Volume 3: CASA Grande Analysis RI-GSI191-V03 Revision 2 Appendix 1 This appendix contains each of the CASA Grande input decks used for the risk-informed GSI-191 evaluation. A detailed explanation is not provided here, but variable names are largely mnemonic, and the information is grouped in associated blocks, so even a casual reader will recognize much of the information and the intent of the data. A reader with some experience with MATLAB programming constructs will immediately recognize the syntax used to define lists (vectors) and tables (arrays) of input values.
Many of the figures presented in the main body of this report can be reproduced using values specified in this input deck. Of particular interest are the random values that that can be sampled during the course of each analysis. It is relatively trivial to add new random variables to the analysis, so eventually most (if not all) of the input parameters will be handled generically as random variables. When point values are desired, the standard deviations of the associated probability distributions are set equal to 0 so that the probability distribution collapses to a point and random sampling simply returns the mean for every sample.
The input decks illustrate that a CASA analysis is data intensive, but all of the input information derives from engineering calculations and from test data that are readily available to plant engineers and analysts. There is very little information here that would not be found in a detailed hand calculation of similar complexity.
The differences between each input deck are described below:
Case 1 is the base case with all trains/pumps operating.
Case 9 is identical to Case 1 except that two LHSI pumps were assumed to have failed.
Case 22 is identical to Case I except that one train was assumed to have failed.
Case 26 is identical to Case 1 except that one train and one additional LHSI pump were assumed to have failed.
Case 43 is identical to Case 1 except that two trains were assumed to have failed and the distribution of spray flow rates was increased from 1,932-2,350 gpm to 2,080-2,600 gpm.
