1. PURPOSEIOBJECTIVE The objective of this calculation is to determine the radiological consequences of a Steam Generator Tube Rupture (SGTR) accident at the Byron and Braidwood Generating Stations, based on the use of Alternative Source Terms (AST) as defined in Regulatory Guide fRG) 1.1831<Ref. 1).

This re-analysis of the design basis tube rupture accident, using the RG 1.183 methodology, seeks to achieve an increase in existing operating margin that can be distributed to various plant systems. Specific design basis changes that are being sought include:

An increased allowance in the amount of time required for the Control Room (CR) to be isolated (i.e., Mode 2), to 30 minutes,

Control Room Intake charcoal adsorber filter credit reduction from 99% to 95%, and

An increase in the maximum allowable unfiltered inleakage into the Control Room, from 100 cfm to 1000 cfm.

Each of these new design basis assumptions will have the benefit of allowing for relaxation in the current plants licensing basis; in terms of testing, surveillance, and other requirements.

This analysis is performed using governing methodologies" assumptions, and inputs for both the Byron and Braidwood plants, and is therefore conservative and applicable to all four units.

2. METHODOLOGY AND ACCEPTANCE CRITERIA R2.1. GeneralDescription The SGTR accident is' postulated as a complete severance of a single S&eamsGenerator<SG) tube.

-This is conservative because the tube material is Inconel, a highlyductile metal alloy, and the most probable mode of failure would be one or more minor tube leaks of varying sizes and undetermined origin.

The tube rupture results in the release of radioactive material from the Byron and Braidwood 4811)

Containment system. For the 3 intact S~s, primary to secondary coolant leakagecontinues to transfer activity into the Secondary Coolant side. This makes it available for release into the environment via steaming through the SG Power-Operated Release Valves 4PORV). For the SG with the ruptured tube, referred to as the ruptured SG, coolant release will take two forms:

Break Flow - un-flashed release of RCS coolant directly into the secondary loop, and made available for steaming release to the environment through the PORV.

Flashed Break Flow - RCS coolant that flashes directly to steam when released from the ruptured tube, and issent through the PORV to the environment.

Based on the extensive derivation of mass releases from this accident for the recentpower uprate calculation effort, and because these releases are unaffected by any of the reference I AST assumption, the bounding Unit 2 power uprate calculation releases for this accident are utilized directly.

SGTR accident mitigation can be described in recovery phases. The majorphases that this analysis uses to model the dose consequences from this event are shown below, along with the time increments that are associated with the sequence of events:

Start of event until Reactor trip; 0- 445 seconds

Reactor Trip until ruptured SG PORV is opened; 445 - 465 seconds

Ruptured SG PORV opening until ruptured SG PORV is isolated; 465 - 1700 seconds

- Ruptured SG PORV Isolation until RCS cooldown isinitiated; 1700 -28600-seconds

. RCS cooldown initiation until Break Flow flashing ceases; 2800 - 300-seconds

End of Break Flow flashing until RCS depressurization initiation; 3000 - 350 seconds

RCS depressurization initiation until all Break Flow ceases; 3500 - 35910seconds

-The calculation of release rates from reference 6 -that will be applied to -eachof these inOrements is discussed in Section 2A4 below. This sequence of events timing does not exactly match he detailed time increment data of reference 6. So the release rates from that reference, which approximately correspond to times in the sequence of events will be used.

Consistent with'RG 1.183 (Ref. 1), two reactor transients that maximize the-radioactivity available for release, were modeled.; In addition to these two transients, the release of the maximum allowed operational concentration of iodine activity in the secondarycooolant system, 0.1 pCi/gm

..... (Ref. 2), is analyzed. This Case simulates the relase of secondary ooolant activity existingpriorlo the SGTR accident.' The dose consequence of this simulation is added to each of the other modeled cases.

NO.ro 6 I CLCUATIN BW-0-002-M IBRO4048& N. I RV.N. I1 2.1.1. Case 1: Dose CDue to Pre-aocident Iodine Spike The first case involves a 60 pCi/gm pre-accident Iodine spike. This'60 pCi/gm spike isconsistent with the B/B Technical Specification operational Reactor Coolant System (RCS) activity concentration limit for a postulated spike. In this scenario, it is assumed that all of the spike activity is homogeneously mixed in the primary coolant, prior to accident initiation.

2.1.2. Case 2: Dose Due to Accident Initiated Concurrent Iodine Spike The second case involves an accident initiated iodine spike that occurs concurrently with the release of fluid from the primary and secondary coolant systems. Regulatory guidance specifies that this spike should result in a release rate from the operating limit defective fuel fraction (-1 %)

that is 335 times the normal rate, and lasts for an 8-hour duration.

2.1.3. Case 3: Dose Due to Equilibrium Secondary Coolant System iodine As discussed, the dose contribution that results from the PORV release of secondary coolant through the SGs. This release of specifically secondary coolant activityexisting prior to 4heSGTR accident, is analyzed, and the dose is added to each of the other modeled cases.

The doses from either accident scenario should not exceed the acceptance shown in -Section 2-8.

2.2. Fuel Damage and Core Source Term The historical design basis at the Byron and Braidwood generating -stations assumes no fuel damage for the postulated steam generator tube rupture event. For this STR accident, the source terms are defined by the Tech Spec (Ref. 2) activity release rates from a maximum failed fuel fraction allowed during operation, which are characterized by the equilibrium 1.0 #Ci/gm Dose Equivalent (DE) 1-131 iodine activity concentration in the primary reactor coolant system. The noble gas inventory in the RCS is based on operation with a conservative worst-case 1% core fuel defects. Because no fuel damage is assumed for this accident, only iodine and noble gas isotopes are modeled to contribute to dose. To identify the worst-caseSGTR accident, however, two different cases of iodine spiking are analyzed, per regulatory guidance (Ref. 1).

2.2.1. Case 1: Pre-Accident Iodine Spike Source Terms The first case- is simply identified as a reactor-pre-accident, transient induced, iodine spike, which raises the primary coolant iodine concentration to the maximum 60 pCi/gmr DE 1-131 value permitted by the BI/B Tech Specs (Ref. 2) at full -power operations, prior to the initiation of the accident. Therefore this case is termed the pre-accident iodine spikecase, and the-derivatiornof the isotopic specific activities input to RADTRAD- are shown in Attachment A.-

2.2.2. Case 2: Concurrent Iodine Spike Source Terms The second case considers that the postulated SGTR event-causes a primaryreactorsystem transient. This transient, in turn, is associated with an iodine spike which increases the iodine release rate from the fuel rods to the primary cooWant to a value 335 times greater than the reease rate corresponding to the 1.0 pCi/gmOE 1-131 equilibrium iodine-conoentrati6nasgiven in the Tech Specs (Ref. 2). As specified by AST guidance, this 335 times activityrelease ratespike is assumed to occur for a duration of 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months (Ref. 1). InRAOTRAD a Nuclide Inventory FileNIF)

(see Attachment D) is designed to input the total isotopic iodine activity that is associated with 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months of activity release at the 335 times rate specified. Then this NIF is used inwcnjunction with a modifiedRelease-Fraction and Timing (RFT)file (see Attachment E), which defines the compoete release of this activity over an 8-hour period. The actual derivation of Wopic specific activity inputs to the NIFPs are shown in Attachment A.

I CALCULATION NO. BYR4-048 & BRW-04-0042-M EV. NO. 1 I PAGE NO. 7 l 2.2.3. Case 3: Equilibrium Secondary Coolant System Iodine Source Terms The case 3 source-term consists simply of the 0.1 pCVgm 1E)1-131 equilibrium secondary coolant activity concentration, as taken from the B/B Tech Specs (Ref. 2}. The total activity availabte for release from both the 'intact SGs and faulted SG are shown in Attachment A (Ref. 5).

-23. Activity Removal Mechanisms in Containment-The design basis SGTR at B/B releases activity directly into the primary RCS, therefore no plateout, or other activity deposition, is credited.

2.3.1. Decay Credited Decay of radioactivity is credited in all compartments, prior to release. This is implemented in RADTRAD using the half-lives in the NIF's. The RADTRAD decay option is used.

2.3.2. Depletion from Leakage Credited For analyses of doses due to release from the RCS volume, the dose results from leakage. It is reasonable to credit the small amount of depletion from the available RCS activity inventory associated with this leakage. This is calculated inherently by the RADTRAD code.

2.4. Release Rates and Partitioning Factors As discussed above, a number of modes of release are indicative of this particular accident scenario. Therefore the varying releases associated with the timing and sequence of everts of this accident have been derived in reference 6. Attachment A to this analysis shows the unit conversion and derivation of the calculated reference 6 values into usable release rates for input to the RADTRAD code. With reference to the coolant masses used in this analysis, minimum masses are conservative because they maximize the concentration of activity available for release from the Steam Generators. As calculated and shown in reference 6, the initial SG coolant masses are smaller than the coolant mass at break flow termination, therefore these initial masses are implemented in this accident analysis. Sections 4.2 and 6.2 document the use of these values.

Activity that originates in the primary RCS is released to the secondary coolant by means of the primary-to-secondary coolant teak rate. This design basisteakrate value is 0.218 gp'm, per intact

SG, totaling 0.654 gpm (Ref. 5). For input into RADTRAD this rate was converted from-gallons per minute to cubic feet per minute, making it 0.02914 cfm, per intact SG, totaling 0.08743 cfdl, as shown in Section 4.2.

The methodology used to modet steaming of activity through PORVs, following the postulated

-SGTR event, is based on an average cumulative release rate through theSG valves. The above

-discussed partitioning factors are applied to these release rates, which were derived in leference 6

-arnd shown in Attachment A. XReference 6 data gives incremental steam mass release rates in pounds per second. For the time increments used in this accident scenario, release rates were derived by taking the averages of these rates over each specified time increment. Then these mass flow rates were converted to volumetric low rates using a basis of cooled liquid-oonditions (i e., 62.4 Ibmf 3 density), as specified by the applicable guidance of RG 1.183 (Ref. 1).

Attachment A details all flow rate values that were used to simulate the SGTR accident as shown in Section 6.

-The ruptured steam generator sees two simultaneous release mechanisms. Primary to secondary coolant leakage through the ruptured tube of the faulted SG that flashes conservativelyooes

-directlyto the environment, without mixing with anysecondarycoolant. Therefore, with this release mechanism, no partitioning of iodine is expected to occur in this 4elease. However, leakagethat does mix with the volume of coolant in the ruptured SG is feteased -by flashing 4o the environment,

I CALCULATION NO. BYR04-048 & BRW-04-0042-M REV. NO. I I PAGE NO. 8 and the applicable partition factor is applied, as discussed below. Reference *6-shows 4hereleases

--that were converted to release rates in Attachment A to model these phenomena..

For all post-accident releases through the SG PORVs, the mechanism forrelease to the environment is steaming of the coolant in the secondary system. Because of this rlease dynamic, RG 1.183 (Ref. 1)allows for a reduction in the amount of activity released to the environment based on partitioning of nuclides between the liquid and gas states of water. For Iodinethe partitioning factor of 0.01 was taken directly from the suggested guidance of reference 1, and applied as shown in Attachment A. Reviewing the specified AST release fractions of reference 1, it is concluded that the only nuclides to be released from the core source term, other~than iodines, are Noble CGas nuclides, and because of the volatility of noble gases, no partitioning is credited for any such isotopes.

In addition to the steam released through the SG PORVs, the steamrelease through the Condenser until the time of Reactor trip and loss of offsite power must also be aocounted for. The total full power steam flow is 16.04E6 lb/hr; therefore the total full power steam flow in the 3 intact SGs is 12.03E6 lb/hr. For steam flow that is released through the Condenser from the 3 intact SGs, an additional 0.01 factor is applied to model partitioning in this pathway.

2.5. Dose Conversion Factors The revised Dose Conversion Factors (DCFs) from the U.S. Federal Guidance Report 11 & 12 (Ref. 16,17) are used for this analysis. The RAOTRAD code inputs these values directly from its internal database.

2.6. Control Room Dose Model For this analysis, as performed using the RADTRAD code, the air volumes characterizing the Control Rooms (CR) at the Byron and Braidwood plants are found to be 230,630 f 3 and 232,872 ft3, respectively (Ref.5, 10). These volumes exclude the Upper Cable SpreadingRooms, which do not have return air flow, and do not require occupancy during post-accident conditions (Ref. 5).

For conservatism and simplicity, these volumes are conservatively modeled as one characteristic 200,000-ft3 volume applied universally for AST analysis.

Using this smaller value, associated with the high flow rates discussed below, is conservative because it leads to the CR reaching its maximum activity concentration faster than if the actual, 3

substantially larger, volume were used. This volume is also well above the 70,275 ft Main Control Room shield volume. Therefore, internal cloud shine dose remains-conservatively-calculated.

As seen in reference 5, Byron and Braidwood plants have a recirculation flow of 43,500 cfm and make-up airflow of 6000 cfm (+/- 10%), totaling 49,500 cfm of total combined flow to-theControl Room volume. However, as per reference 13, there-could be a failure scenario where open inlet and outlet dampers on the unused CR makeup train result in an additional 1500 cfm of filtered intake into the CR during Mode 2 operation. Therefore, for conservatism, asstated in refefence 13, this 1500 cfm was rounded up to 2000 cfm, and is added to the 49,500cfm total combined flow during Mode 2. Of this 51,500 cfm, a separate volume designated as the "opperlcable spreading room", or upper CSR, receives an un-recirculated intake flow of 1319 cfm at Byrron, and 2430 cfm at Braidwood (Ref.-11). Because they are un-recirculated, these flows are -subtracted from the 51,500 cfm total combined flow, making the Mode 2 adjusted combined flows to the Byron and Braidwood Control Rooms 50,181 cfm and 49,070 cfm, respectively. To then calculate the Mode 2 adjusted make-up flow to the CR volume, the ratios of these adjusted combined flows to the CR volume, over the total combined flow, are multiplied by the 000 dm make-up flow. This

I CALCULATION NO. BYR04-048 & BRW-04-042-M REV. NO. I I PAGE NO.9 respectively results in Mode 2 make-up flows of 7795 cfm (+/-10%) and 7623 cfm (+/-10%) to the Byron and Braidwood Control Rooms.

Following CR Mode 2 isolation, the credited CR filtration is 99% for the HEPA and 95% for the charcoal filters, and the intake flow rate is 8575 cfm, which is the upper 10% bound of the Byron 7795 cfm make-up flow shown above. The charcoal filtration efficiency of 95% reflects a reduction (from the Ref. 5 value of 99%) in the filter credit taken. This intake rate is used because, with the specified intake, inleakage, and recirculation flow rates, filter efficiencies, and CR volume, sensitivity analyses have shown for this analysis that it is conservative to maximize the Mode 2 airflow into the Control Room.:

The CR intake is assumed to be unfiltered for the Mode 1 first 30 minutes of the accident, to simulate'a newly analyzed allowance for manual CR Mode 2 isolation. During this 30-minute period, it is conservative to assume that the possible 2000 cfm of filtered intake does not flow through the Control Room. This is because this filtered flow would act to "clean" the unfiltered air being brought in by the other unfiltered flows (i.e., normal intake and unfiltered inleakage) during these 30 minutes.- Sensitivity analyses using RADTRAD confirmed that such additional filtered intake during Mode I would lower the CR dose consequences. Therefore, before CR emergency Mode 2 isolation the adjusted combined flows to the Byron and Braidwood Control Rooms become 48,181 cfm and 47,O70 cfm, respectively, and subsequently actual make-up flows become 5840 cfm (+/-10%) and 5705 cfm (+/-10%) to Byron and Braidwood, respectively. So, the unfiltered intake flow rate into-the CR during this initial 30-minute period is assumed to be 6424 cfm; the upper 10%

bound of the Byron 5840 cfm make-up flow shown above.

As the BIB Control Rooms are modeled, a conservatively reduced (by the - 10% lower bound) recirculation train flow rate of 39,150 cfm is used<Ref. 5, 11). This recirculation train is filteredby an 80% aerosot particulate (pre-filter) and 90% elemental and organic iodine (charcoal) filters. No reduction in the efficiency of these filters was sought.

For additional conservatism and to allow for margin in future analyses, an unfiltered inleakagerate allowance of 1000 cfm is modeled for the accident duration.

Any air that enters the CR originates from a source that is characterized by a dispersion factor, calculated using ARCON96, in reference 12. The total dose in the Control Room over the 720-hour period is the result of the released activities that enter through the air intake, either filtered or unfiltered.

2.7. EAB and LPZ Dose Model Between the Byror and Braidwood plants, the Exclusion Area Boundary (EAB) and LowPopulation Zone (LPZ) VIo's have been determined in reference 12, and at worst-case, awe respectively located 445m and 181Om from the postulated release locations.

2.8. Acceptance Criteria Radiological doses resulting from a design basis SGTR for a control roomoperator and aperson located at EAB or- LPZ are to be less than the regulatory dose limits as-given in Table 2.

3. ASSUMPTIONS

1. Core inventory was based on a DBA power level of 3658.3 MWthi which is t102% of the Rated Thermal Power Level of 3586.6 MWth, to account for measurement uncertainty.

2. There is no fuel damage as a result of the postulated steam generator tube rupture accident at Byron and Braidwood Generating stations (Ref. 5).

3. In the case of a postulated iodine activity release rate spike, the spike release is assumed to occur for a period of 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , when the activity available -or release from the fuel has been conservatively depleted (Ref. 6).

4. The activity released from the fuel in the case of a pre-accident spike is assumed to be instantaneously and homogeneously mixed with the RCS (Ref. 1).

5. All iodine released from the SGs is assumed to be of the elemental species. This is done for RADTRAD simulation considerations, and isconsistent with the RG 1.183 specification of 97% elemental and 3% organic, because elemental and organic iodine are identically treated by the computer model Ref. 1).

6. The Control Room HVAC emergency Mode 2 at B/B is initiated 30 minutes after the start of this design basis accident.

7. The ruptured S steam release of 9.42E4 -Ibm given in reference 6 forthe time period 0 to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months will be modeled from time the ruptured SG PORVopens <465 seconds), which is 20 seconds after reactor trip, until the ruptured SiG PORV is isolated (1700 seconds). The 2 to 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months steam release is used as given in reference 6-for 2 to 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months (Ref 6).

8. The intact SG steam release of 5.44E5 Ibm given in reference 6 for the time period 0 to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months will be modeled from time of RCS cooldown initiation 9600 seconds) until the RCS cooldown is terminated and RCS depressurization is initiated (3500 seconds). The 2 to 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months steam release is used as given in reference 6 for2 to 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months (Ref 6).

9. In addition to PORV steam releases, the full power steam release through the Condenser-(16.04E6 1b/hr) until the time of reactor trip and loss of offstepower will be accounted for (Ref. 5).

12). The x/a's used are, conservatively, the worst-casecombination of values from each Unit of each respective plant; whether it be Byron or Braidwood.

All releases from PORVs to the Environment utilize the l/ associated with release ; from the PORV/Safety Valve house to either the normal Control Room Fresh Air Intake or t0e Control Room Turbine Building Emergency Air Intake. Activity released during the initial 30 minul es of the accident goes to the normal CR fresh air intake; after this period, when the CR is assurned to have been isolated, the emergency air intake located in the Turbine Building is used.

All releases from the PORV/Safety Valve house are considered elevated releases iue to the high steaming rates, therefore per regulatory guidance, the associated Va's have been reduced by a factor of 5, as justified below.

4.1.1. Justification for Application of Elevated Release Credit Regulatory guidance of RG 1.194 (Ref. 4), indicates a factor of 5 reduction in the ground level X/Q value calculated with ARCON96 isjustified for energetic releases from steam relief valves or atmospheric dump valves, if (1)the release point is uncapped and vertically oriented and (2) the time-dependent vertical velocity exceeds the 95th-percentile wind speed (at the release point height) by a factor of 5.

As a precedent for such a factor of 5 credit applied to a plant similar to Byron and Braidwood, the Virginia Electric and Power Company letter to the NRC of November 20, 2003 (Ref. 14) was reviewed. This letter shows PORV steam exhaust releases are uncapped, vertically oriented, and, have vertical-velocities about an order of magnitude above the thresboldneeeded ito qualify for the factor of 5 reduction, for the bounding .choked sonic flow conditions of the saturated steam release.

Like North Anna, the Byron and Braidwood PORVs are uncapped and vertically oriented. The 95th-percentile wind speeds for Byron are 7.61 meters per second at Byron or6.89 meters .per second at Braidwood for the 30 foot tower level, and 11.26 meters per second at Byron and 10.92 meters per second at Braidwood for the 250 foot tower level. These wind speeds are -comparable to those provided for North Anna in the referenced letter. The Byron and Braidwood PORV release rates for all steam release accidents are greater than those developed for North Anna in the referenced letter.

Therefore, it is concluded that the factor of 5 reduction is acceptable atByron and Braidwood for all steam release accidents involving PORV release from the steam generators.

6. CALCULATIONS 6.1. Source Term Calculation For the RADTRAD calculation, a list of 60-core isotopic nuclides and their activities were extracted from Attachment'A of Design Analyses BYR04-047 &BRW-04-0041-M, Rev. 1 (Ref.-9) for input into the RADTRAD NIF (see Attachment D). However', forthis analysis only the iodine and noble gas activities, which are conservatively characterized by operation with 1%core fuel defects and the equilibrium and spiked release rates from that fuel, define the source terms, as discussed in Section 2.2 above. The derivation of the specific activity inputs to the RADTRAD NIF for calculational purposes for each case is shown Attachment D. RADTRAD uses these activities, in curies per megawatt, and then applies nuclide release fractions and a specified core power to calculate the source term for a given case. The AST release fraction associated with lodines and noble gases is assumed to be 100%, and for Case 2.only, iodine is released over an 8-hourperiod.

6.2. Dose Calculations The RADTRAD v. 3.03 computer code is used to determine B/8 Units I & 2 SGTR accident doses at the three dose points cited in Reg. Guide 1.183 (Ref. 1); the Exclusion Area Boundary <EAB),

Low Population Zone (LPZ), and Control Room. fRADTRAD is a simplified model of RADionuclide Transport and Removal And Dose Estimation developed for, and endorsed by, the NRC as an acceptable methodology for reanalysis of the radiological consequences of design basis accidents.

In this analysis RADTRAD is used to estimate- the releases using the reference Alternative Source Term source terms and assumptions. The RADTRAD code uses a combination -of tables andlor numerical models of source term reduction phenomena to-determine the time-dependent dose at user-specified locations for a given accident -scenario. The code system also provides the inventory, decay chain, and dose conversion.4actortables needed forthedosecalcutation. The technical basis for the RADTRAD code is documented in NUREGtCR-64Ref. 15).

See Section 2 and subsequent sections for descriptions of the calculational simulations'detaied in the tables that follow.

SUMMARY

AND CONCLUSIONS Table 7.1 below provides the results from the Case 1 and Case 2 simulations that were modeled using the RADTRAD 3.03 code. The total dose for the two cases includes the dose result from the Case 3 simulation, therefore for convenience, the doses shown in the Table include the Case 3 dose.

Using the design basis assumptions, described methodology, and credited margin relaxation of this analysis, the limiting CR dose is 0.76 rem TEDE. This limiting dose, and all other doses, are well below their respective acceptance criteria, so it is verified that this design basis Steam Generator Tube Rupture accident is sufficiently mitigated at both Byron and Braidwood Generating Stations.

Attachment E Demonstration that Smaller Control Room Volume Used in Analysis Bounds Actual Byron and Braidwood Control Room Volumes I. Purpose The purpose of this attachment is to demonstrate that using a smaller value of 200,000 ft3 to bound both the Byron and Braidwood Control Room (CR) volumes of 230,830 ft3 and 232,872 ft3 , respectively, provides the conservative approach to modeling of CR doses in this accident analysis.

II. Approach Shown in this attachment, is a re-evaluation of this worst-case design basis accident using a Control Room volume of 240,000 ft3 instead of the 200,000 ft3 volume used in the analysis. It is intended to show that the implementation of the larger Control Room volume leads to a lower end-of-accident dose consequence than that which is calculated when implementing the smaller volume. For this particular AST Steam Generator Tube Rupture (SGTR) accident analysis, CR doses from the two runs shown in this attachment are summed to give the re-evaluated CR dose from the worst-case DBA-SGTR, for comparison to the same dose calculated in the analysis.

III. Results Shown below is a table comparing the dose from the bounding design basis accident case as compared to the test case of this attachment that uses the larger Control Room volume.

It is clearly shown that the dose assessment calculated in the Control Room using a smaller volume of 200,000 ft3 is more conservative than that using a larger volume of 240,000 ft3 .
