Purpose This calculation is prepared by Polestar Applied Technology, Inc. for Vermont Yankee (VY) to determine the offsite and control room doses following a DBA Loss of Coolant Accident (LOCA).

It evaluates the radiological impact at the Exclusion Area Boundary (EAB), Low Population Zone (LPZ) and control room (CR). The analysis includes three release pathways (or cases) as follows:

Case 1: Leakage from Primary Containment (PC) directly to the environment (Secondary Containment (SC) or Reactor Building (RB) bypass);

Case 2: Leakage from the PC into the RB and subsequent release to the environment via the Standby Gas Treatment System (SGTS) and the plant stack; Case 3: Leakage from the PC via the Main Steam Isolation Valves (MSIVs) to the Main Condenser (MC) and subsequent release to the environment.

All of these pathways are analyzed for two accident scenarios: one in which the failure of an SGTS train delays drawdown of the SC (affecting Cases 1 and 2) and one in which an MSIV fails to close (affecting Case 3). Summaries of the results are presented in Table 1.

These doses provided for information only - no limits apply

PSAT 3019CF.QA.08 Pg 4 of 58 Rev 0 This table shows that all cases meet the applicable limits at all locations (Exclusion Area Boundary or EAB, the Low Population Zone outer boundary or LPZ, and the Control Room or CR).

Methodology This dose analysis was conducted to fully comply with NRC Regulatory Guide 1.183 (Reference 1).

The calculation determines the offsite and control room doses due to a DBA-LOCA. The computer code RADTRAD 3.02a (Reference 2) was used to determine the activity releases, offsite dose and CR dose. Verification of the RADTRAD runs was performed using the STARDOSE 1.01 computer code (Reference 3) and is documented in Appendix B.

Assumptions Assumption 1: The Case 1 and 3 releases are from either the RB (Case 1) or the MC/turbine stop valves (Case 3), both at ground level. The Case 2 releases are from the plant stack.

Justification:

The exact leak location for the release from the MC is not known, but it is assumed to be at the location of the turbine stop valves where the leakage bypassing the MC is also assumed to occur. The RB bypass is also treated as a ground-level release. It may occur from two locations: the RB siding on the refueling elevation during drawdown (i.e., the establishing of a stable negative pressure in the RB at the beginning of SGTS operation) or at the RB penetration for the nitrogen system.

Assumption 2: Event timing is as follows:

LOCA occurs at t = 0 minutes. Degraded core cooling leads to core damage.

Release from core to PC begins at t = 2 minutes. A drainline pathway is established from the main steam lines to the MC.

SGTS starts automatically and RB drawdown is achieved by t = 10 minutes.

Drywell sprays are initiated at t = 15 minutes.

Further core damage and associated activity releases are terminated at t = 122 minutes by assumed restoration of core cooling. Drywell and torus airspace become well-mixed at that time.

Within several hours, Standby Liquid Control (SLC) is initiated and the contents of the SLC system have become mixed with the suppression pool water.

By t = 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , the containment pressure has decreased to less than 5.5 psig, and the PC leak rate has become a factor of two less than the maxium PC leak rate (except for Engineered Safety Feature (ESF) liquid leakage).

By t = 720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months , essentially all particulate activity has been leaked or deposited and gaseous I-131 (the principal dose contributor excluding particulate I-131) has gone through nearly four half-lives. The dose calculation is terminated in accordance with Reference 1.

Justification:

The timing of all of these events is based on Reference 1 except for establishing the drainline pathway, drawdown, drywell spray initiation, drywell and torus mixing, SLC injection, and containment leak rate reduction justification. These are covered in the following justification.

Establishing the DrainLine Pathway

PSAT 3019CF.QA.08 Pg 5 of 58 Rev 0 The drainline pathway to the MC is expected to be established very early in the accident response. Even if such a response were delayed for half an hour, the dose impact would be minimal (less than two percent of the CR dose limit).

Therefore, the exact timing of this action is not considered critical.

Drawdown Time The time at which the SC pressure becomes sufficiently low to justify no further outleakage is an important parameter of the DBA-LOCA analysis. The value used is that specified in Reference 4, Item 8.11.

Drywell Spray Initiation Drywell spray initiation is called for in the plant procedures. For an accident involving the degree of core damage postulated in Reference I for the DBA-LOCA (and used herein), the plant procedures would be called upon to guide operator actions. This guidance calls for drywell spray operation if the radiation level in the drywell exceeds 4000 rads/hour (Reference 4, Item 9.4) and, for conservatism, a minium 10-minute operator response time is provided for (Reference 4, Item 9.1).

Based on Reference 5, the release of the noble gas and iodine gap activity to the PC using shutdown core inventory (i.e., early in the accident) will yield an indication on the containment high-range monitor of nearly 6000 rads/hour in about five minutes. This can be determined by (1) noting that the high range monitor response would indicate 6.05E5 rads/hour for 100% noble gas release and 5.89E5 rads/hour for 100% halogen release and (2) recognizing that the gap release rate for both noble gas and halogens is assumed to be 0.1 core inventory per hour or 0.00 167 per minute (Reference 1). Before sprays are started, natural removal is minimal (it is neglected in this analysis); and, therefore, the dose rate is accumulating at the rate of 0.00167(6.05E5 + 5.89E5) = 1994 rads/hour/minute once the release begins at t = 2 minutes. By t = 5 minutes, the indicated dose rate will be at least 5.98E3 rads/hour, well in excess of the 4000 rads/hour calling for spray operation and well before the assumed spray actuation time of t = 15 minutes (accident time) or 13 minutes after the start of the gap activity release.

The VY sprays are designated Safety-Related and their availability is governed by the Technical Specifications.

Drywell and Torus Mixing Reference 1 establishes that only the drywell volume should be credited for diluting the activity release from the core for a BWR. For Mark ml containment designs, specific instructions are then provided as to how to subsequently treat mixing between the drywell and the remainder of the containment. For Mark I and Mark II plants, however, no specific guidance is provided. Instead, the general guidance is that the torus airspace "... may be included provided there is a mechanism to ensure mixing... ".

Polestar is aware that AST applications have been accepted by the NRC in which the full containment volume (drywell + torus airspace) has been credited from t = 0 with no apparent explanation or justification of the mixing credit (i.e.,

the justification for mixing does not appear to have been addressed in either the submittal or in the NRC Safety Evaluation; e.g., Reference 6). However,

PSAT 3019CF.QA.08 Pg 6 of 58 Rev 0 Polestar believes that mixing will be limited between these two volumes during the fission product release phase because of the generally quiesent state of the drywell during core degradation; and, therefore, it is inappropriate to include the torus airspace volume initially (per NRC guidance) without actually analyzing the drywell-to-torus flow.

Following the restoration of core/core debris cooling, considerable thermal-hydraulic activity in the PC will result, and the drywell and torus airspace volumes will become well-mixed. Beyond t = 122 minutes, therefore (the end of the release phase), a mechanism does exist to mix these two volumes; and that assumption has been made in this analysis.

SLC Injection The injection of the SLC sodium pentaborate is justified by the plant procedures (as with drywell sprays). If core damage is expected or identified as a result of normal and emergency core cooling not being available or sufficient, the plant procedures provide guidance for injecting all available water sources into the reactor vessel. This would include SLC injection. Therefore, SLC injection is expected for this event.

The VY SLC system is designated Safety-Related and its availability is governed by the Technical Specifications.

Per Reference 6, SLC injection will maintain the suppression pool pH above 7.0 for 30 days, and radioiodine re-evolution does not need to be considered.

u Containment Leak Rate Reduction Justification Reference 1 requires justification for implementing a factor of two reduction in PC leak rate at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months after the start of the accident. No such justification is required for PWRs.

Typically, PWR containment pressures are reduced rapidly by the use of containment sprays, while BWRs have not credited containment sprays in accident analysis (although they are generally Safety-Related, and the impact of their use on containment pressure is generally described in the plant FSAR).

The use of sprays for VY is already discussed above. With sprays in operation, the drywell pressure is reduced to -20 psia (5.3 psig) at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months (Reference 4, Item 8.10) from a peak value of 58.7 psia (44 psig), a ratio of 0.12 based on the gauge pressure.

Polestar has reviewed a number of PWR FSARs, and the containment pressure ratio at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months (gauge pressure at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months divided by the peak calculated gauge pressure) is typically about 0.3 or less. If the leak path is sufficiently restrictive so that choked flow is not occurring and the problem may be treated as incompressible flow (low Mach Number), a factor of 3.33 reduction in containment pressure will yield a reduction in volumetric flow of about 1.8 (approximately a factor of two) if the density is assumed constant. Since the containment is a closed system, the density of the non-condensables will not change during depressurization (the pressure decrease being the result of a temperature reduction) except for steam condensation. However, the steam condensation effect cannot be neglected, and the chart on the following page (Figure 1) shows the relationship of leakage fraction vs. gauge pressure for incompressible flow with the density effect taken into account.

PSAT 3019CF.QA.08 Pg 7 of 58 Rev 0 The chart shows that for VY's peak pressure of about 44 psig (see Reference 4, Item 8.3), the factor of two reduction in volumetric leak rate is not achieved until a pressure of about 5.5 psig is attained, about a factor of eight reduction in containment pressure. Polestar believes that NRC has previously given credit for a factor of two reduction in containment leak rate at 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months in some BWR AST applications with apparently as little as a factor of two reduction in containment pressure (Reference 7); however, a factor of eight seems to be a more sound technical basis. VY meets this basis at approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months since the pressure reduction for VY (with spray credit) is more than a factor of eight; i.e., it is a factor of 44/5.3 or 8.3.

Operation of the CAD actually reduces the doses because activity is removed from the PC atmosphere (where it is vulnerable to release via RB bypass and MSIV leakage) and released via the plant stack with relatively little dose impact. CAD operation actually acts as a removal mechanism.

Justification:

This assumption was identified as a result of the independent review of this calculation and a further discussion of this point is provided in Appendix B.

Assumption 4: Iodine resuspension in the main steam lines is neglected.

Justification:

PSAT 3019CF.QA.08 Pg 8 of 58 Rev 0 Proprietary Material Removed Assumption 5: Accident time = time after release + two minutes.

Justification:

Unless otherwise stated, all times given in this calculation are accident times, beginning at t = 0 with the assumed DBA-LOCA leading to core damage. Even for the largest LOCA, there is a two-minute delay for BWRs between the start of the accident and the start of release.

PSAT 3019CF.QA.08 Pg 12 of 58 Rev 0 Dose Conversion Factors: Default FGRI 1&12.INP file from Reference 2 Calculation As previously described, the three cases included in the overall RADTRAD model are the RB bypass (two releases directly from the PC to the environment), the RB releases via the SGTS and the plant stack (including ESF leakage), and MSIV leakage (via the main steam lines employing an Alternative Leakage Treatment or ALT scheme to collect MSIV leakage and direct it to the main condenser). The RADTRAD model is shown on Figure 2.

Figure 2 - RADTRAD Model Case I - Leakage from Primary Containment Directly to the Environment (Bypass Pathway)

This is the first pathway that makes a significant contribution to the DBA-LOCA doses. There are two components of this pathway. The first is pre-drawdown PC leakage (0.8 %/day). This is leakage from the PC that occurs prior to establishing a sustained negative pressure in the SC; and, therefore, it is assumed to leak directly to the environment from the refueling elevation via sheet-metal siding.

The second component is the nitrogen supply which penetrates the PC and then penetrates the RB on the RB's south side. Leakage from the PC through this system's closed containment

PSAT 3019CF.QA.08 Pg 13 of 58 Rev 0 isolation valves (CIVs) could bypass the SC and the SGTS filters and could also result in a ground-level release.

Pathway Assumptions The drawdown bypass occurs during the first 10 minutes of the DBA-LOCA, accident time. Even though there is a period during this 10 minutes when the RB pressure is actually subatmospheric, the full 10 minutes is used.

The release from the core is assumed to enter the drywelH only. Mixing within the entire PC is not assumed to occur until after the end of the release (see Assumption 2).

No credit is taken for natural deposition in the drywell during the drawdown period; credit for drywell deposition does not begin until drywell sprays start at t = 15 minutes. Nor is any credit for deposition taken in the unspecified leak path(s) that lead to this bypass.

The sustained bypass through the nitrogen system is treated very conservatively. No credit is taken for deposition in piping or components (either inside or outside the PC), and this includes the nitrogen heater. Both this release and the drawdown bypass are assumed to be released at ground level.

The drawdown bypass corresponds to the PC leak rate of 0.8 G/day. The sustained bypass via the nitrogen supply pathway has an assumed leak rate of 5 scfh which (using the same conversion as that of Appendix A for the maximum per line MSIV leak rate of 62 scfh) is 5 x (23/62) = 1.85 cfh =

0.031 cfm. For the minimum drywell volume of 1.284E5 ft3, this is 0.035 %9/day. After the PC is assumed to become well-mixed at the end of the release (2.033 hours3.819444e-4 days 0.00917 hours 5.456349e-5 weeks 1.25565e-5 months ), this changes to 0.019 %/day.

Finally, beyond 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , this leak rate becomes 0.010 %/day (see Assumption 2).

For this case, the two parallel main steam line flowpaths to the ALT volume (see Appendix A for definition and discussion) are included in the model as well as the pathway to the RB. These are discussed in more detail for the MS1V leakage pathway RADTRAD model and the RB/SGTS/plant stack pathway RADTRAD model, respectively. They are included in this model only so that the associated leakage out of the PC is properly accounted for.

RADTRAD Analysis The 60 radionuclides in the default RADTRAD.nif file are used; however, the file is modified to include the core inventories from Reference 4.

The worst two-hour EAB dose interval for this pathway begins at t = 0.00333 hours.

Single-Failure Considerations If there is not a single-failure of a SGTS train, there will not be a positive pressure period for the RB and there will not be any drawdown bypass. There will continue to be a RB bypass associated with the nitrogen system. To analyze this event, it is only necessary to change the first two junctions as follows and to dispense with the weighted average CR X/Q for the bypass pathways during the drawdown period (i.e., to use only the X/Q for the N2 supply):

PSAT 3019CF.QA.08 Pg 35 of 58 Rev 0 Case 2 - Leakage from Primary Containment to the Environment via the Reactor Building, SGTS, and Plant Stack (RB/SGTS/Plant Stack Pathway)

For this pathway, a single junction is provided from the "Drywell" control volume (before 2.033 hours3.819444e-4 days 0.00917 hours 5.456349e-5 weeks 1.25565e-5 months ) and a single junction is provided from the "DW and WW" control volume (after 2.033 hours3.819444e-4 days 0.00917 hours 5.456349e-5 weeks 1.25565e-5 months ) to represent the 0.8 %lday PC leakage to the RB. Added to this is the ESF leakage which is modeled as a continuous 1 gpm (0.134 cfm) volumentric flow from the "Pool" control volume to the RB.

Pathway Assumptions Airborne releases from the PC to the RB begin after the drawdown period. ESF leakage is assumed to begin immediately.

Since the "Pool" control volume receives the full release in parallel with the "Drywell" and the "DW and WW" control volumes, five percent of the iodine (total) is in elemental and organic form. If the particulate were filtered out entirely in the junction from the "Pool" to the RB, only 5% of the iodine would be released to the RB. Ten percent is required. Therefore, the particulate filter is set at 94.74% permitting another 5% of the iodine to become airborne. This iodine does not have the correct chemical form; but since the SGTS filter efficiencies are all 95% and since the CR has no incoming air filtration, the dose calculation for radioiodine is correct.

This approach to ESF leakage also "inadvertently" permits 100% of the noble gas and slightly more than five percent of the particulate in the one gpm "Pool" control volume leakage to be released to the RB along with the intended 10% of the radioiodine. This is conservative.

The RB releases its activity to the environment through the SGTS filters and the plant stack. The RB volume is set numerically (and artificially) equal to the nominal SGTS flow rate (in cfm).

This provides essentially zero holdup for the RB.

RADTRAD Analysis The 60 radionuclides in the default RADTRAD.nif file are used; however, the file is modified to include the core inventories from Reference 4. The nif file used to analyze this pathway is identical to that used for the bypass pathway model discussed above.

The standard BWR DBA-LOCA release fraction and timing file is used. It is identical to that used for the bypass pathway model discussed above.

Single Failure Considerations If there is not a single-failure of a SGTS train, there will not be a positive pressure period for the RB, and there will not be any drawdown bypass. To analyze this event, it is only necessary to change the first junction as follows:

0. 0000E+00 Case 3 - Leakage from Primary Containment to the Environment via the Main Steam Lines and the Main Condenser (MSIV Pathway)

For this pathway, two junctions are provided from the "Drywell" control volume and two from the "DW and WW" control volume to represent the two leaking steam lines. These junctions all terminate in the "ALT' control volume. The "ALT" control volume represents the isolated main steam lines out to the turbine stop valves. This control volume can leak directly to the environment (representing main condenser bypass), and it can leak to the main condenser (drain line connection). The main condenser can then leak to the environment.

The RADTRAD model for this pathway also includes leakage from the PC to the RB so that the PC activities are determined correctly. However, no leakage to the environment is permitted other than that through the MSMVs. Drywell sprays are modeled in an identical manner to that described for the bypass pathways above.

Pathway Assumptions The details for developing the RADTRAD modeling of the MSIV leakage pathway are covered in Appendix A. The removal efficiency summary is as follows:

Even though this reduction in MSIV leak rate would increase the filtration efficiencies, that benefit is conservatively omitted.

End of Scenario File Note that for this file, the X/Qs are shifted from those in the Design Inputs section. This is because the worst two-hour EAB dose was identified as being from 3.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months to 5.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months (using a constant X/Q); and therefore, the X/Qs for all pathways were adjusted to place the highest value at 3.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months .

Single Failure Considerations To consider a single failure of an MSIV to close, Appendix A considers two MSIV leakage pathway models. The first (using the terminology of Appendix A) is "A" in which the space between the MSIVs is ignored. This would correspond to a failure of one MSIV to close. Under that condition, the space between the MSIVs could be considered part of the drywell (inboard MSIV fails to close) or part of the control volume defined by the closed inboard MSIV (outboard MSIV fails to close) and the turbine stop valves. The former is the more conservative assumption, and it is on that basis that the "A" removal efficiencies were calculated; i.e., they were kept the same as "B2".

The second pathway model considered in Appendix A consists of control volumes "B 1" and "B2" in series. This pathway model is for lines with both MSIVs closed. To model a single failure of an MSIV, it is only necessary (1) to use the average particulate DF for the two Appendix A models (instead of that for the B 1IB2 models alone) for the RADTRAD input for the pathways from the ALT volume to the main condenser and to the environment and (2) to reduce the ALT volume by the volume of one line between the MSIVs corrected for the

PSAT 3019CF.QA.08 Pg 56 of 58 Rev 0 expanded flow in the ALT as compared to that in the space between the two MSIVs. This is explained more fully in Appendix A. The changes in the RADTRAD input are as follows:

PSAT 3019CF.QA.08 Pg 58 of 58 Rev 0 Conclusions For control room operators and for the general public, the radiation dose acceptance criteria for all design-basis accidents are as defined in Reference 1. For the DBA-LOCA, the limits are 5 rem TEDE for Control Room and 25 rem TEDE for offsite locations. (For the control Room, the exposure interval is 30 days with allowance for partial occupancy after the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . The EAB dose is based on the worst 2-hour exposure, and the LPZ dose is based on 30-day exposure just as for the Control Room.) The analysis shows that a DBA-LOCA will result in Control Room operator doses and offsite doses to the general public that are below the stated limits.

PSAT 3019CF.QA.08 APPENDIX A Page Al of 18 Table of Contents for Appendix A Determination of Volumetric Flows and Removal EfficiencieslDFs For Alternative Leakage Treatment (ALT) 1.0 Purpose Al 2.0 Introduction Al 3.0 Design Input Data Al 4.0 Assumptions Al 5.0 Computations and Analyses A2 6.0 References A12 Figure Al A13 Figure A2 A14 Figure A3 A15 Spreadsheet Al A16 1.0 Purpose The purpose of this appendix is to determine aerosol and elemental iodine removal coefficients in the main steam lines and main condenser to be used in Alternate Source Term dose calculations as an Alternative Leakage Treatment (ALT) for MSIV Leakage.

2.0 Introduction Aerosol and elemental iodine removal due to sedimentation and adsorption, respectively, is credited in the main steam lines and in the main condenser. It is possible that an inboard or an outboard MSIV of one main steam line may fail to close. The other three main steam lines are assumed to be normally isolated.

In these lines, sedimentation will be credited in the inboard-to-outboard MSIV volumes and in the volumes from the outboard MSIVs to the points where the drainlines tap off. Finally, sedimentation will be credited in the main condenser, where activity leaking out of the main steam lines is collected.

Removal coefficients will be independently calculated for aerosols and elemental iodine.

3.0 Design Input Data Design input data is taken from Ref Al (item numbers provided below). They are as follows:

1.

DW sprays assumed to start at t = 15 minutes accident time (Item 9.1)

2. MSIV leakage: 124 scfh total, 62 scfh max per line at peak accident pressurefemperature(ltem 3.17)

3.

Peak accident conditions: P = 58.7 psia (44 psig), T = 338 F (Item 8.3)

4.

Steam line temperature: 550 F (Item 8.4)

5. Volume from inboard to outboard MSIV (for each main steam line): 26 cuft (18 ft long from Item 7.3,16.124" ID from Item 7.2)

6.

Volume from Outboard MSIV to Stop Valve (for each main steam line): 263 cuft (206.1 ft long from Item 7.3, horizontal runs only, 16.124* ID from Item 7.2, for conservatism and to account for bends, use 90%)

7.

Main Condenser Leakage Bypass: 0.8% (Item 7.5)

8.

Main Condenser Volume: 107,000 ft3 (Item 3.5) 4.0 Assumptions

PSAT 3019CF.QA.08 APPENDIX A Page A2 of 18 Proprietary Material Removed Assumption 2:

Justification 2:

It is assumed that the actual representative droplet size for the VY spray nozzles in the drywell would be between 1000 and 1500 m.

These are typical values for mass mean droplet diameters for BWR spray systems. Two diameters are used to demonstrate that the results for main steam line/condenser deposition are not sensitive to a particular value.

5.0 Computation and Analysis Three main steam lines are assumed to be intact and unfaulted up to the turbine stop valves, while either an inboard or an outboard MSIV is assumed to be failed open in the remaining main steam line (practically eliminating consideration of any portion of the piping between the reactor vessel and the closed MSIV for that line).

Proprietary Material Removed As for the main steam line with the failed open MSIV, removal is being credited in only one single piping volume between the outboard MSIV and turbine stop valve.

5.1 Leakage Rate into the Main Steam Lines 5.1.1 Mass Flow Rate Section 3.0 provides mass leak rates into the steam lines. One assumes that one-half of the total drywell to steam lines leakage enters one failed line (one MSIV open, referred to as line A") and one-half leaks into one other line ("B", assumed to be intact), which means that the two other intact lines ("C" and U0")

are assumed to be leak tight.

The MSIV leakage partitioning for analysis is, therefore, as follows:

Faulted Line A Intact Line B Intact Line C Intact Line D 62 scfh 62 scfh No Leakage No Leakage

PSAT 3019CF.QA.08 APPENDIX A Page A3 of 8 Note that line B is made up of two sub control volumes: (i) B1, inboard MSIV to outboard MSIV and (ii)

B2, outboard MSIV to turbine stop valve.

The case matrix for the aerosol removal analysis in the steam lines is then:

Case Leakage Volume where Aerosol Removal Occurs A:

62 SCFH Outboard MSIV to Turbine Stop Valve B:

BI 62 SCFH Inboard to Outboard MSIV B2 62 SCFH Outboard MSIV to Turbine Stop Valve 5.1.2 Volumetric Flow Rate Since Section 3.0 provides MSIV leakage only in terms of mass flow rates, one needs to convert these SCFH values into volumetric flow rates (CFH) based on the actual conditions in the drywell. The mass flow rate of 62 scfh is already at peak accident conditions, so the conversion is straightforward. The pressure decrease is a factor of four from 58.7 psia to 14.7 psia, and the temperature decrease from 338 F to standard conditions (70 F) is a factor of (798 R/530 R). The pressure factor tends to make the volumetric flow from the drywell less than the specified (and tested) SCFH and the temperature factor tends to make it greater.

The overall decrease is a factor of 2.7; i.e., from 62 scfh to 23 cfh or 0.383 cfm. In terms of the fractional leakage of drywell volume for each of the two leak paths, the result is (0.383 cfm)(60 min/hour)(24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/day)/128,370 ft3 = 0.43 0/o/day. In terms of combined drywell and torus airspace volume, it is (0.383 cfm)(60 min/hour)(24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/day)/(1 28,370 + 103,932) ft3= 0.24 0//day.

5.2 Leakage Rate out of Each Steam Line Volume Volume B1 The volumetric flow in the space between closed MSIVs is assumed to be the same as that leaving the drywell.

Leak Rate (B1) = 23 cfh

= 23/26 = 0.885 vol/hour Volumes A and B2 The volume between the outboard MSIV and the turbine stop valves in a single main steam line is 263 ft3 (see Section 3.0). In this space, the pressure is assumed to be atmospheric, with a temperature of 550 F (see Section 3.0). Therefore, one needs to apply a temperature correction to calculate the volumetric flow rates out of that space. One will find:

Leak Rate (A)

= 62 scfh x (460 + 550)/(530)

= 118.2 cfh = 1.97 cfm per line

= 118.2/263/2 = 0.225 vol/hour*

Assuming two main steam line volumes per leaking line because of cross-connections Leak Rate (2) = Leak Rate (A) 5.3 Leakaae in and out of the Main Condenser Volume The total mass flow rate entering the main condenser from the two upstream control volumes A and B2 is the total MSIV tested leak rate (124 scfh) decreased by 0.8% to account for condenser bypass; i.e., to 123 scfh.

PSAT 3019CF.QA.08 APPENDIX A Page A4 of 18 In terms of volumetric flow entering the condenser, it amounts to (1 - 0.008) times the sum of the volumetric flows leaking out of the two steam lines, that is to say 0.992 x (118.2 + 118.2) = 234.5 cfh =

3.91 cfm. The leakage bypassing the condenser is 0.008 x 234.5/0.992 = 1.9 cfh = 0.032 cfm.

In the condenser, the pressure is assumed to be atmospheric (as it is in the A and B2 main steam line control volumes) and the temperature is assumed to be standard (compared to 550 F in the main steam lines). Consequently, the volumetric flow rate going out of the main condenser equals the volumetric flow rate leaking out of the steam line volumes A and B2 but converted to standard temperature (i.e., multiplied by the ratio 530 Rl/ 010 R). One obtains a volumetric flow rate of 123 cfh or 2.05 cfm. This is conservative in that no steam condensation in the main condenser is credited, only a decrease in the temperature of the leakage. The leakage of 2.05 cfm is about three percent per day of the 107,000 ft3 main condenser volume or 1.15E-3 volumes per hour.

Main Condenser Volume:

For the VY main condenser, it is about 8 meters from the elevation of the condenser centerline (237.47')

to the center of the main condenser bellows (average of 265.75' and 262' or 263.88' - see Section 3.0).

The primary drain pathway enters the main condenser at about the same elevation as the condenser centerline (at 237.04'). With a main condenser volume of 107,000 ft3 (see Section 3.0) and a sedimentation height in the main condenser of 8.0 meters, one calculates a sedimentation area of about 4,078 ft2 (ratio of the volume to the sedimentation height). This is very conservative. The total tube area is 3.15E5 t2, and dividing by ic to relate the horizontal projected area of the tubes to the surface area of the tubes, the result is about 1 E5 ft2. This is almost 25 times the credited sedimentation area. While it is unreasonable to expect that the entire projected surface area of the tubes would act as a surface for sedimentation, using only four percent of that projected surface is clearly conservative.

Therefore, one has:

Settling Area:

5.6 Calculation of the Elemental Iodine Removal Coefficients in the Steam Lines and Main Condenser The model used in the main steam lines is the Bixler Model from NUREG/CR-6604 (Ref A5, Equation 29

p. 212).

[Note that the Cline correlation mentioned in Ref A5 was reviewed, and this review confirmed that the expression of the elemental iodine deposition velocity, U,1, contains an exponential, unlike what Ref A5 shows. Therefore, the following expression for elemental iodine deposition velocity, Ui, has been modified from Ref A5 to include the exponential.]

Volume B1:

Elemental iodine removal in B1 is neglected.

Volume B2:

Same as Volume A:

IleI =58 %

The model used in the main condenser is taken from SRP 6.5.2 (Ref A4).

Per Ref A4, the removal coefficient Xw for elemental iodine in the containment (applied here to the main condenser) is obtained as follows:

= KWA, V

where K, is the deposition velocity (K, = 4.9 m/hr per Ref A4), Ak is the surface area for elemental iodine deposition in the main condenser, and V is the volume of the main condenser.

Surface Area:

4078 ft2 (from Section 5.5)

Volume:

107,000 ft3 (from Section 3.0)

This surface area is the same as the main condenser sedimentation area, and it is very conservative to use such an area for elemental iodine deposition.

Knowing that Kw = 4.9 m/hr = 16.1 ft/hr one obtains:

kw= 0.61 /hr With 74.k Mc = 1.155E-3/hr, one calculate an efficiencyn, using equation 13, rI = 99.8 %

PSAT 3019CF.QA.08 APPENDIX A Page Al I of 8 For comparison, if one were to use the Bixler deposition velocity (assuming standard conditions in the main condenser):

K = exp(2809/295K - 12.5) = 5.1 E-2 cm/sec = 1.8 m/hr Knowing that Ki = 1.8

/hr = 5.9 ft/hr one obtains:

X,= 0.225 /hr With

,4eakMC

= 1.155E-3/hr, one calculate an efficiencyil, using equation 13, T1w = 99.5 %

It is believed that the containment conditions more closely approximate the main condenser conditions than do the main steam line conditions; and given the conservatism of the deposition area, it is acceptable to use the higher removal efficiency.

One may notice that the elemental iodine removal efficiency in the condenser is greater than the corresponding removal efficiency for particles; i.e., 99.8% > 95.1%. In this regard, it is important to note that very small particles are actually removed more readily by diffusion than by sedimentation and that when the removal process becomes dependent on diffusion, the smaller the particle, the better the removal. In the limit, gases diffuse more readily than particles; and, therefore, it is not inconsistent that gases would be removed more readily than very small particles in the main condenser.

One may also take note of the fact that in the main body of the calculation, the spray removal rate in the drywell for elemental iodine was set equal to that for particulate because of the large amount of surface area presented by the particulate for elemental iodine adsorption. The decision as to whether to use the particle removal efficiency or the elemental iodine removal efficiency from SRP 6.5.2 when quantifying elemental iodine removal in the condenser needs to be based on the surface area of the airborne particulate compared to the surface area of the structures since airborne elemental iodine would tend to adsorb on airborne particles and be removed with it.

In containment, even during spray operation, particles are plentiful. Therefore, it is correct and also conservative (since the rate is limited) to assume that elemental iodine will be removed at the same rate as particles.

In the condenser, the situation is different as there is very little particle airborne (due to efficient removal processes upstream). Thus, only a limited fraction of the airborne elemental iodine will be removed at the same rate as that of the airborne particles, the rest being removed on the condenser surfaces, at the rate calculated using the SRP 6.5.2 model.

5.7 Calculation of Combined Removal Efficiencies/DFs to be used in RADTRAD Model Having calculated removal efficiencies for each main steam line control volume and the main condenser, one needs to develop combined removal efficiencies to be used directly in the plant RADTRAD model for purpose of dose calculation. In the piping mode of RADTRAD, DFs are used instead of efficiencies.

As discussed in the main body of the calculation, VY makes use of the Alternative Leakage Treatment of ALT concept of managing MSIV leakage. In this concept, the main steam lines beyond the MSIVs are isolated post-LOCA and treated as a holdup volume. One or more drainline pathways are provided to direct MSIV leakage from this volume to the main condenser for additional holdup.

The RADTRAD model creates a control volume ALT" which represents the volume of four steam lines (since they are cross-connected) from the outboard MSIVs to the turbine stop valves. Added to this volume is the volume of two steam lines between the two MSIVs. These two steam lines are each

PSAT 3019CF.QA.08 APPENDIX A Page A 12 of 8 assumed to be leaking at 62 scfh with a volumetric flow of 0.383 cfm. Beyond the outboard MSIVs, the 0.383 cfm is assumed to expand to 1.97 cfm (23 cfh to 118.2 cfh). Since the RADTRAD model uses the expanded volumetric flow for the junction from main steam line volume to the main condenser and since the volume of the main steam lines are to be added to it, the volume between the MSIVs is increased by the ratio of 1.97/0.383 to preserve the correct holdup time. Therefore, the ALT control volume has the volume 4 x 263 ft3 + 2 x 26 ft3 (1.97/0.383) = 1319 ft3. If one MSIV is assumed to be failed open, the volume becomes 4 x 263 ft3 + 26 ft3 (1.97/0.383) = 1185 ft3.

Volumetric flow rate to Cond:

234.5/2 cfh = 117.3 cfh = 1.96 cfm Removal Efficiency for Particles:38% in B1, 71 % in B2, 82% for two control volumes in series; i.e., series efficiency = 1 - (1 - 0.38) x (1 - 0.71)

DF for Particles = 1/(1 - 0.82): 5.56 Removal Efficiency for Elem i:

58% (Bl ignored for elemental iodine)

DF for Elem I = 1/(1 - 0.58):

2.38

For one pathway with one closed MSIV and one pathway with two closed MSIVs, the average DF of 4.51 should be used for particles. The total flow to the main condenser is 234.5 cfh.

Condenser Bypass Leakage:

Bypass of the main condenser may occur due to direct leakage from the main steam lines to the HP turbine. The fractional bypass is 0.8% or (2 x 118.2) - 234.5 cfh = 1.9 cfh = 0.032 cfm. This bypass will experience removal in the main steam lines, but not in the main condenser. The removal DFs for this bypass will be the same as those above.

Condenser Leakage:

Volumetric flow rate from Cond: 123 cfh = 2.05 cfm Removal Efficiency for Particles: 95.1%

Removal Efficiency for Elem : 99.8%

The Design Input Data and Assumptions are the same as those used in the main body of the calculation.

The AST application for the LOCA is consistentent with Reference B-2.

STARDOSE Calculation The STARDOSE LIBFILEI.TXT file is included as Attachment B-1. Common to all AST STARDOSE runs, it contains the radionuclide input data. The core inventories listed in Column 5 of the LIBFILE1.TXT are from Reference B-3. The Dose Conversion Factors (Column 8 for whole body and Column 12 for CEDE) are the same as in the main body of the calculation.

Decay constants (per second) come from Reference B-4.

Input data files are provided as Attachments B-2 and B-3.

Attachment B-2 corresponds to RADTRAD Cases B + 2B + 3A (Primary Containment Leakage Direct to Environment (With SGTS Failure) + Release Via RB and Plant Stack (With SGTS Failure) + Release via Main Steam Lines and MC (No MSIV Failure)).

Attachment B-3 corresponds to RADTRAD Cases A + 2A + 3B (Primary Containment Leakage Direct to Environment (No SGTS Failure) + Release Via RB and Plant Stack (No SGTS Failure)

+ Release Via Main Steam Lines and MC (With MSIV Failure).

In conducting the RADTRAD analysis, Containment Atmospheric Dilution System (CAD) operation was neglected as mentioned in Assumption 3 contained in the main body of the calculation. However, its operation was evaluated using STARDOSE to determine its effect on radiation dose.

According to the Vermont Yankee FSAR, if hydrogen is detected in the primary containment as a result of a LOCA, the CAD would be used to maintain oxygen concentrations below 5%. After the LOCA, the primary containment would be pressurized at a rate of approximatley 40 scfm until the pressure reached 28 psig. The CAD system at VY is designed to allow pressurization to be initiated within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of the LOCA. The containment would then be isolated until hydrogen generation by radiolysis caused the oxygen/hydrogen concentration to approach the flammable region. At that time, the containment would be vented at a rate of 20 scfm (treated in this analysis as 20 cfm). As venting would progress, the hydrogen concentration would increase because its generation would exceed its removal by venting. As containment pressure decreased,

PSAT 3019CF.QA.08 Page B2 of 3 Rev 0 repressurization would begin and continue until the pressure returned to 28 psig. This process of continuous venting, with pressurization cycling as required, would continue as long as necessary (Reference B-5). It is assumed that the CAD purge begins at t = 192 hours0.00222 days 0.0533 hours 3.174603e-4 weeks 7.3056e-5 months (Reference B-6).

STARDOSE was utilized to determine the radiation dose impacts of the CAD system venting.

Attachment B4 contains an input data file that includes CAD venting along with the DBA-LOCA with SGTS Failure scenario. The results show that the radiation doses at the EAB, LPZ and Control Room are relatively unaffected, actually decreasing for the limiting Control Room dose while increasing somewhat for the LPZ dose. The two-hour EAB dose is unaffected. Therefore, venting resulting from CAD operation does not create a case that requires further analysis.
