g Analysis 5 - Page 2 of 20 1.0 PURPOSE The 09/25/2011 dc panel ED-11-2 fault isolated letdown flow and increased charging flow. This resulted in rising pressurizer level and represented a potential challenge to pressurizer safety relief valves. Steam and/or water release from pressurizer safety relief valves could result in a stuck open relief valve and subsequent above-core, vapor-space loss of coolant accident.
This evaluation investigates the integrated plant response to a stuck open safety relief valve within the context of the loss of dc event. Theis attachment evaluation is a margin evaluation of employing the charging pumps as a makeup source. The results are provided as information, only.
The current event tree success criteria require HPSI as the makeup source. No changes to this criterion have been made.provides a basis for the event tree structure and success criteria used in the logic model.
This evaluation uses the Modular Accident Analysis Program (MAAP) model for Palisades.
2.0 CONCLUSION
Thermal-hydraulic analysis in this evaluation demonstrates the success criteria for above-core, vapor-space LOCAs can be satisfied with two charging pumps providing makeup..
As long as secondary side cooling is available for decay heat removal, the transient does not require high pressure safety injection to preclude core damage, apart from additional failures that once-through-cooling would be required to mitigate the event.
Long term heat removal via the steam generators or transition to shutdown cooling could then become a success path, even when a SRV sticks open - provided inventory makeup is available.
For example, charging with safety injection refueling water tank (SIRWT) inventory, conserved by terminating sprays, or via HPSI in recirculation mode would maintain adequate core cooling.
3.0 INPUT 3.1 MAAP 4.0.6 Model The baseline model is developed and documented in the MAAP 4.0.6 model parameter file [1] and thermal hydraulic analyses [2]. The baseline model is used as the starting point for this evaluation.
MAAP is a computer code that simulates the response of light water reactor power plants during severe accidents. Given a set of initiating events and operator actions, MAAP predicts plant response as a function of time.
Plant response under severe accident scenarios is complex and is best evaluated in an integrated manner. The primary system and containment responses are sensitive to the calculated pressures, temperatures, flows, and event timings. These parameters also affect operator action timings, the radionuclide release timings, and the mitigating system performance assessments.
Proper plant-specific characterization of the severe accident progression is important to the realistic representation of the plant and highly desirable for a PRA assessment.
3.2 Event-Specific Plant Data The timeline in Attachment 01 considered the best available information, including PI data, PPC data, control room recorder data, operator logs, procedures filled-out during the event, and interviews and discussions with operations.
Inputs to this evaluation are based on and consistent with the results of the timeline construction, to the greatest extent possible. Specific data sources are given below.

g Analysis 5 - Page 3 of 20 3.2.1 Process Information (PI) Data Event-specific plant data for various plant parameters are obtained from the PI data archive. PI is software quality assurance (SQA) category "C" (important to business) per Entergy SQA procedure EN-IT-104. The plant process computer (PPC) provides data to the PI system. PPC is SQA category "B" (regulatory commitments). Most PPC points are calibrated via technical specification surveillance procedure or by preventive maintenance and controlled calibration sheets.
Part of the PI server system runs on the PPC. This portion monitors selected points every second to test against the exception threshold change value.
If the change value is exceeded, the data is passed to the PI server and recorded. The PI server also compares the new value against previous values to see if it still fits on a line within the compression limit. If yes, the data is discarded, otherwise it is added to the archive. For pump starts, the compression limit is simply a change in state (on-off or start-stopped),
if 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> have passed without an archive update, one is made regardless. PI provides generally accurate long term values and greater amounts of data when events are changing rapidly.
Since the event resulted in the loss of two preferred ac buses, various PPC/Pl data points were unavailable and not recorded in the PPC/Pl systems.
This evaluation uses PI data both directly and in support of other data sources for:
steam generator level steam generator pressure auxiliary feedwater flow pressurizer level pressurizer pressure charging flow primary coolant system average temperature 3.2.2 Control Room Recorder Data Event-specific plant data for various plant parameters are obtained from control room recorder data.
Certain Yokagawa-type control room indicators have the ability to record and store data. Plant instrumentation and control engineers collected post-event data from these recorders and provided both display screen shots and data to the PRA group.
This evaluation uses Yokagawa recorder data both directly and in support of other data sources for:

Analysis 5 - Page 4 of 20 3.2.3 Operator Logs Event-specific plant data for various parameters and events are obtained from electronic operator round (eSOMS) logs.
This evaluation uses eSOMS logs mainly in support of other data sources.
3.3 Condensate Storage Tank The condensate storage tank (T-2) was 87°F as recorded in the electronic operator rounds (eSOMS) at 0752 on 9-25-2011.
3.4 Atmospheric Dump Valves (ADVs)
Operation of the atmospheric dump valves (CV-0779, CV-0780, CV-0781, and CV-0782 ) via quick open and manual control is unavailable until power is restored to preferred ac bus EY-10.
The loss of dc event resulted in loss of power to the inverter that supplies preferred ac bus EY-1 0. Power can be restored by restoring power to the dc bus and re-energizing the inverter or aligning the bypass regulator to re-energize the preferred ac bus. EY-10 was placed on bypass regulator at 16:46, one hour forty minutes into the event.
For cases where ADVs are restored, valve operation to achieve decay heat removal and plant cooldown in accordance with technical specification limits on cooldown rate is used.
In nearly all the MAAP cases reported herein, the ADV's are modeled as "failed closed".
3.5 Auxiliary Feedwater Auxiliary feedwater pump P-8A does not start on auxiliary feedwater actuation signal due to loss of preferred ac buses EY-10 and EY-30. However, P-8A remains available to be started from the control room or locally. After restoration of power to ED-11-1 and EY-10 or EY-30, P-8A is capable of automatic start should steam generator levels fall to the auxiliary feedwater actuation signal setpoint.
The loss of dc event de-energized left channel dc power. This results in automatic start of P-8B (mechanical governor maintains normal turbine/pump speed) with flow control valves wide open. Steam supply to P-8B was manually isolated at 16:03. P-8B flows to each steam generator are given in 0. Attachment 04 provides an accounting of AFW delivered to the steam generators during the event.
Right channel dc power remained available. Auxiliary feedwater pump P-8C starts on auxiliary feedwater actuation signal given P-8A failure to deliver required flow (due to loss of EY-10, EY-30 and loss of left channel dc). Flow control valves set to 165 gpm to each steam generator. P-8C flow to E-50A was isolated due to overfill concerns at 15:44. P-8C flow to E-50B was isolated at 16:09 due to adequate E-50B level.

The loss of dc event resulted in failure of the in-service channel A pressurizer level and heater control circuit. With no power to channel A the control program defaulted to maximum flow from the operating pumps (93 gpm: P-55A - 53 gpm; P-55B - 40 gpm).
At approximately 31 minutes into the event operators switched pressurizer level control to channel B to enable pressurizer spray. With channel 'B' in service charging flow reduced to the minimum flow from operating pumps (73 gpm: P-55A - 33 gpm; P-55B - 40 gpm).
Had channel 'B' been in service at the time of the event, charging flow rate would have been at minimum flow from the operating pumps from time zero.

0 4.0 ASSUMPTIONS 4.1 Major Assumptions 4.1.1 AFW flow delivery is under predicted.
Basis: AFW flow is limited based on S/G level control. Therefore, the Table 3.5-1 data is automatically throttled to match decay heat.
Bias:
Conservative, as the calculated primary system pressure is greater.
4.1.2 MAAP S/G Modeling Limited Basis: The Palisades MAAP model runs hotter than the RELAP Version 3 Mod 2 model.
Comparisons
[3] between MAAP and RELAP have shown that for station blackout sequences with subsequent once-through -cooling (OTC), that the comparative behavior between the codes for the most part, is very similar.
The single biggest difference is the more rapid steam generator dryout calculated by MAAP. This is considered due to the MAAP S /G modeling limitations.
Below, the MAAP hot core node temperature peaks at about 1200°K. No peak is exhibited from the RELAP results.
Bias:
Conservative, as the MAAP results produce higher pressures and temperatures for above core breaks.

_y Ent^r,o g
Analysis 5 - Page 7 of 20 4.2 Minor Assumptions 4.2.1 The onset of core damage has been defined as the time when peak core temperature reaches 1800 F.
Basis:
The onset of core damage should be developed consistent with the desire to be as realistic as possible and consistent with current best practice.
If the MAAP code is used to predict core response, it is recommended that core damage be defined as the time when peak core temperature reaches 1800°F.
This is based on the characteristics of the MAAP code and the guidance provided in the MAAP4 applications guide. A peak core temperature of 1800°F is also consistent with the general guidelines for the definition of core damage provided in the EPRI Probabilistic Safety Assessment (PSA) Applications Guide [4].
Bias:
This is considered conservative per Assumption 4.1.2 and given that the fuel design limit is 2200°F.
4.2.2 Quench Tank Model Disabled Basis: The PORV discharge model to the quench tank was disabled, to improve code execution time.
Bias:
This is considered neutral as it results in a slightly higher early containment heat load and somewhat slows the PCS blowdown transient.
5.0 ANALYSIS Illustrative and/or important MAAP cases are described below. Not all MAAP cases are explicitly discussed. The case name (prefix of the input file name) indentifies the specific MAAP run. The purpose, description and conclusion of each run are provided; selected plots follow.
Two basic types of cases are analyzed:
n Cases utilizing event-specific timing and/or plant response n
Cases utilizing bounding timing and/or plant response.
The first set of cases is meant to envelope the actual event to ensure the actual plant response is bounded by the second set of cases. No cases have been performed to precisely match actual event plant response in all respects. Various model conservatisms add margin to the bounding case results.
Following each case the selected plot results are presented following by the specific MAAP input file is listed.

The peak temperature of 1650°F remained less than the success criteria limit of 1800°F.
Figure 5.2.1-2 displays the primary coolant system pressure (PCS).
Figure 5.2.1-3 presents the unsecured charging flow dropping from 93 gpm to 73 gpm at 36 minutes into the event.
Figure 5.2.1-4 shows the safety injection refueling water storage tank (SIRWT) dropping about 8 feet during the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period.
Figure 5.2.1-5 demonstrates that 1 containment air cooler (CAC) is sufficient to keep containment pressure less than the 55 psig design value.
Figure 5.2.1-6 indicates that the condensate storage tank (T-2) dropped from about 72 feet to 26 feet during the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> duration.

In summary, Case 11 results show that if 2 charging pumps, SIRWT water and AFW are available then HPSI injection is not required.
However, the logic model as described in Section 6.2 conservatively requires HPSI for success in all RAS sequences, to achieve a safe and stable state for the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> mission.
