1. PURPOSE/OBJECTIVE The objective of this calculation is to determine the radiological consequences of a Control Rod Ejection Accident (CREA) at the Byron and Braidwood Generating Stations, based on the use of Alternative Source Terms (AST) as defined in Regulatory Guide (RG) 1.183 (Ref. 1).

This re-analysis of the design basis rod ejection 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 increase in the Containment leakage rate, from 0.1 percent per day to 0.2 percent per day,

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 2.1. General Description 2.1.1. Case 1: Containment Leakage CREA For Case 1, the ejected control rod is postulated to breach the reactor pressure vessel <RPV),

effectively causing the equivalent of a small break loss of coolant accident. In this case, all activity from damaged fuel that has been mixed with the primary coolant of the Reactor Coolant System (RCS) leaks directly to the containment volume. This flashed release will instantaneously and homogeneously mix with the containment atmosphere (Ref. 1), and subsequently, be available for release to the environment via a Containment leak rate limit, or La, conservatively increased from 0.1% per day to 0.2% per day for this accident analysis. As is historically the case at Byron and Braidwood (B/B), and as per RG 1.183 (Ref. 1)guidance, the leak rate is conservatively reduced by 50% after 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , based on the Containment pressure decreasing over time.

2.1.2. Case 2: Steam Generator PORV Release CREA For Case 2, no breach of the RPV is postulated following the rod ejection. In this case, reactor coolant system (RCS) integrity is maintained and all activity from damaged fuel that has been mixed with the RCS leaks to the secondary side coolant through the Steam Generator (SG) tubes via the Tech. Spec. primary to secondary coolant leakage rate of 1.0 gpm. From here, activity is available for release to the environment by steaming of the SG Power-Operated Relief Valves (PORVs). An average rate of release is used, and has been calculated in reference 7. In addition to the activity released from the primary to secondary coolant, pre-existing Tech. Spec. iodine activity in the secondary coolant system is postulated to also be released.

The doses from either accident scenario should not exceed the acceptance shown in Section 2.9.

2.2. Fuel Damage and Core Source Term For conservatism, the CREA core source terms are those associated with a DBA power level of 3658.3 MWth, as per reference 6, which includes an additional 2% power over that of the full licensed power to account for uncertainty.

The sudden rod ejection and localized temperature spike associated with the CREA results in the damage of less than 10% of the core (Ref. 6). The TODI No. BYR-04-020 8 BRW-2004-0029 of reference 6 shows that only 2.5 % of the damaged core releases melted fuel activity, i.e., a 0.00375 fraction of the total core melts. Therefore for both cases, the source term available for release is associated with this fraction of melted fuel and the fraction of core activity existing in the gap.

In addition, to comply with the guidance of reference 1, peaking was addressed. Historically at 6BlB no peaking factor was applied to core activity for the CREA analysis; this was likely'due to the conservative factors applied to fuel burnup and damage assumptions. As indicated in the 8/8 UFSAR Section 15.4.8.2.2 (Ref. 2), only 10% of the fuel rods enter into the DNB phase following a design basis CREA, therefore only 10% will be damaged. However, historical analyses assumed 15% of the fuel is damaged, thereby assuming a 1.5 factor of additional activity. As also stated in the B/B UFSAR (Section 15.4.8.3), the assumption of 15% damaged fuel was 'to provide additional conservatism inthe radiological consequence analysis". For this analysis, to satisfy the guidance of R.G. 1.183 (Ref. 1), the 1.7 radial peaking factor, used for the conservative single assemblyB/B Fuel Handling Accident (FHA) analyses is added to the activity available for release during this

CALCULATION NO. BYR04-045 & BRW-04-0039-M REV. NO. I PAGE NO. 6 accident. This approach conservatively accounts for any radial peaking the core may have experienced.

2.3. Activity Release Fractions Release fractions and transport fractions are per Regulatory Guide 1.183, Appendix H and Table 3 (Ref. 1). To comply with this regulatory guidance, 10% of the core inventory of iodine and noble gas is assumed to be in the fuel-clad gap. Additionally, Table 3 of reference 1 shows that 12% of the core cesium and rubidium should be assumed to be in the fuel-clad gap and postulated to be released in its entirety from the damaged 15% of the total core. However, to accommodate the consideration of extended fuel burnup, in excess of the reference 1 assumptions, the cesium and rubidium release fraction is doubled. Although analyses have shown that isotopic activity fractions in the fuel-clad gap may in fact decrease when 'burning" the fuel longer than the 62 GWd/MTU specified in reference 1, this 100% increase in the gap fractions is used as an accepted and conservative means of bounding all extended burnup phenomena. With regard to the fraction released from melted fuel, it is assumed that 90% of the core inventory of iodine and noble gas, and 76% of the core cesium and rubidium remain available for release due to melting (these are the remaining fractions of activity that are not in the fuel-clad gap). Again in compliance with RG 1.183 (Ref. 1), it would be assumed that 100% of the noble gases, 25% of the iodines, and 50% of the cesium and rubidium (considered particulate/aerosol nuclides) released from the melted fuel would be available for release from containment. However, for this analysis the assumption of 25% of the iodines being available for release was increased to 50%. This was done to prevent a

'double counting" of the iodine removal due to plate-out in containment, because this analysis credits Powers' Natural Deposition model for plateout (Ref. 15), as opposed to the historically assumed 50% plateout. See Attachment D for the detailed derivation of the release fraction values.

These activity release fractions are input to the RADTRAD code through the use of the Release Fractions and Timing (RFT) file.

2.4. Airborne Activity Removal Mechanisms in Containment As discussed below only natural deposition, decay, and leakage are credited.

2.4.1. Natural Deposition RG 1.183 (Ref. 1) guidance on this issue is:

"Reduction in airborneradioactivityin the containment by naturaldeposition within the containment may be credited.Acceptable modelsfor removal of iodine and aerosols are describedin NUREG/CR-6189, "A Simplified Model of Aerosol Removal by Natural Processesin Reactor Containments". The loater model is incorporatedinto the anahlsiscode RADTRAD. The priorpractice of deterministicallyassuming thata 50% plateout of iodine is releasedfrom the fuel is no longer acceptableto the NRC staffas it is inconsistentwith the characteristicsof the revised source terms."

For B/B, the RADTRAD computer program, including the Powers Natural Deposition algorithm based on NUREG/CR-6189, is used for modeling aerosol deposition in Containment. No natural deposition is assumed for elemental or organic iodine. The lower bound (10%) level of deposition credit is used.

CALCULATION NO. BYR04-045 & BRW-04-0039-M REV. NO. ] PAGE NO.7 2.4.2. Decay Credited Decay of radioactivity is credited in all compartments, prior to release. This is implemented in RADTRAD using the half-lives in the Nuclide Inventory File (NIF). The RADTRAD decay plus daughter option is used. In reality, daughter products such as xenon from iodines or iodines from tellurium are unlikely to readily escape from the matrix in which the parent iodine or tellurium is contained. Nevertheless, the RADTRAD feature to include daughter effects is selected for conservatism.

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

2.5. Steaming Release Rates and Partitioning Factors Activity that originates in the primary RCS is released to the secondary coolant by means of the primary-to-secondary coolant leak rate. This design basis leak rate value is a total of 1.0 gpm {Ref.

6). For input into RADTRAD this rate is converted from gallons per minute to cubic feet per minute, making it equal to 0.1337 cfm, as shown in Section 4.2.

For Case 2, the release to the environment is associated with the secondary coolant steaming from the Steam Generators. Because of this release 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 Iodine, the partitioning factor of 0.01 was taken directly from the suggested guidance of reference 1. However, there is no explicit guidance with regard to other particulate nuclides. Reviewing the specified AST release fractions of reference 1,it is concluded that the only nuclides other than lodines to be released from the core source term are Cesiums, Rubidium, and Noble Gases. For cesiums and rubidium, a partitioning factor of 0.0055 is used, bounding the applicable ANSI Standard, ANS/ANSI-18.1-1999 (Ref. 14). This value bounds the actual 0.00529 factor that is shown for Cs-1 34 in reference 14, which has the largest partitioning factor of these such isotopes. Because of the volatility of noble gases, no partitioning is postulated for any such isotopes.

Based on the extensive derivation of mass releases from this accident for the recent-power uprate calculation effort, and because these releases are unaffected by any of the reference 1 AST assumptions, the bounding power uprate calculation releases for this accident are utilized directly.

The methodology used to model steaming of activity through PORVs, following the postulated CREA event of Case 2, uses an average cumulative release rate through the SG valves that, for simplicity and conservatism, is reduced in steps. The above discussed partitioning factors are applied to these release rates, which were derived from the total time increment mass releases in reference 7. The following table shows the time steps, isotopic partitioning factors, end associated release rates; conversion of this data was performed using a basis of cooled liquid conditions (i.e.,

62.4 Ibm/ft3 density), as specified by the applicable guidance of RG 1.183 (Ref. 1).:

I CALCULATION NO. BYR04-045 & BRW-04-0039-M I REV. NO. I I PAGE NO. 8 l 2.6. 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 RADTRAD code inputs these values directly from its internal database.

2.7. 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 ft3 and 232,872 ft3 (Refs. 5, 8), respectively. These volumes exclude the Upper Cable Spreading Rooms, 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-ft 3 volume applied universally for AST analyses.

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, substantially larger, volume were used. This volume is also well -above the 70,275 ft 3 Main Control Room shield volume. Therefore, internal cloud shine dose remains conservatively calculated.

As seen in reference 6, 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 the Control Room volume. However, as per reference 12, there could be a failure scenario where open inlet and outlet dampers on the unused CR make-up train result in-an additional 1500 cfm of filtered intake into the CR during Mode 2 operation. Therefore, for conservatism, as stated in reference 12, this 1500 cfm was rounded up to 2000 cfm, and is added to the 49,500 cfm total combined flow during Mode 2. Of this 51,500 cfm, a separate volume designated as the 'upper cable spreading room", or upper CSR, receives an un-recirculated intake flow of 1319 cfm at Byron, and 2430 cfm at Braidwood (Ref. 10). 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 8000 cfm make-up flow. This 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 rnot 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 1 would lower the CR dose consequences. Therefore, before CRemergency Mode 2 isolation the adjusted combined flows to the Byron and Braidwood Control Rooms become

I CALCULATION NO. BYR04-045 & BRW-04-0039-M R EV. NO. I I PAGE NO. 9 48,181 cfm and 47,070 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 B/B Control Rooms are modeled, a conservatively reduced (by the - 10% lower bound) recirculation train flow rate of 39,150 cfm is used (Refs. 6,10). This recirculation train is filtered by an 80% aerosol 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 inleakage fate 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 11. 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.

2.8. EAB and LPZ Dose Model Between the Byron and Braidwood plants, the Exclusion Area Boundary (EAB) and Low Population Zone (LPZ) "/O's have been determined in reference 11, and at worst-case, are respectively located 445m and 1810m from the postulated release locations.

2.9. Acceptance Criteria Radiological doses resulting from a design basis CREA for a control room operator and a person 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 MWth, which is 102% of the Rated Thermal Power Level of 3586.6 MWth, to account for measurement uncertainty.

2. 10% of the fuel is damaged during the initiation of this accident, and is assumed to have failed (Ref. 6).

3. 10% of the core inventory of noble gases and iodines are released from the fuel gap (Appendix H of Ref. 1). Release fractions of other nuclide groups contained in the fuel gap are detailed in Table 3 of Regulatory Guide 1.183 (Ref. 1), and to account for gap fraction uncertainty due to expected extended fuel burnup, fractions from the referenced table are doubled.

4. 2.5% of the failed fuel rods will melt during the CREA, as per reference 6.

5. 100% of noble gases and 50% of the iodines contained in the melted fuel fraction are assumed to be released to the reactor coolant (Appendix C of Ref. 1). Fractions of other nuclides released from the melted fuel are used from Table 1of Regulatory Guide 1.183 (Ref. 1). Though these are described as LOCA values for fuel melt release, they are used to conservatively supplement for "silent" guidance in regards to the other nuclide groups.

6. The activity released from the fuel from either the gap or from fuel pellets is assumed to be instantaneously mixed with the reactor coolant within the pressure vessel (Ref.

1).

7. All iodine released from the SGs is assumed to be of the elemental species. This is done for RADTRAD simulation considerations, and is consistent 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).

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

9. For the Containment leakage case, all leakage is assumed to be at an increased La of 0.2% per day for the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months and 0.1% per day thereafter.

10. For conservatism, a peaking factor of 1.7, based on the FHA single fuel assembly radial peaking factor, is added to the activity available for release, in order to account for any operational radial peaking the core may have experienced.

4. DESIGN INPUT 4.1. Z/Q Calculations(Meteorology)

The CR x/O values input to RADTRAD were taken from the ARCON96 results of the B/B Design Analyses BYR04-050 & BRW-04-0044-M, as performed by Washington Group International (Ref.

11). The '/O's used are, conservatively, the worst-case combination of values from each Unit of each respective plant; whether it be Byron or Braidwood.

All releases from PORVs to the Environment utilize the x/O associated with releases from the PORV/Safety Valve house to either the normal Control Room Fresh Air Intake or the Control Room Turbine Building Emergency Air Intake. Releases from Containment utilize a 'diffuse" source x/o from the Containment Building to the respective CR intakes, as described in reference 11. Activity released during the initial 30 minutes of the accident goes to the normal CR fresh air intake; after this period, when the CR is assumed 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 due to the high steaming rates, therefore per regulatory guidance, the associated x/o'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. 5), indicates a factor of 5 reduction in the ground level X/Q value calculated with ARCON96 is justified 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 (lRef. 13) was reviewed. This letter shows PORV steam exhaust releases are uncapped, vertically oriented, and have vertical velocities about an order of magnitude above the threshold needed to 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 or 6.89 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 at Byron and Braidwood for all steam release accidents involving PORV release from the steam generators.

The CR atmospheric relative concentrations used for PORV releases are as follows:

x/I =1.77E-03 sec/mi (0-0.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months ) (2-hr limiting CR Fresh Air Intake VO)

The release fractions associated with all of these nuclide groups, as detailed in Regulatory Guide 1.183, were applied to their given groups, and input into the RADTRAD 'RTF" files, as seen in Attachment C. RADTRAD uses these two files combined with the power of 3658.3 MWth (Ref. 6) to develop the source terms for this CRDA.

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 B/B Design Analyses BYR04-047 & BRW-04-0041-M, Rev. 1 (Ref. 8) for input into the RADTRAD NIF (see Attachment B). RADTRAD uses these activities, in curies per megawatt, then applies nuclide release fractions and a specified core power to calculate a core source term. The AST release fractions associated with all of these nuclide groups are derived using guidance outlined in Regulatory Guide 1.183, as described in Section 2.3 above. The final gap release and fuel melt release fractions are then input into the RADTRAD 'RTF", as seen in Attachment C. RADTRAD applies the input core power of 3658.3 MWth XRef. 6) to these two input files to develop the core source term activities for this CREA.

6.2. Dose Calculations The RADTRAD v. 3.03 computer code is used to determine BIB Units I & 2 CREA 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. RADTRAD is a simplified model of RADionuclide Iransport 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.

RADTRAD estimates the releases using the reference Alternative Source Term source terms and assumptions. The RADTRAD code uses a combination of tables and/or 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 factor tables needed for the dose calculation. The technical basis for the RADTRAD code is documented in NUREG/CR-6604 (Ref. 15).

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

Using the design basis assumptions, described methodology, and credited margin relaxation of this analysis, the limiting CR dose is 2.55 rem TEDE. This limiting dose, and all other doses, are well below their respective acceptance criteria, so it is verified that this design basis Control Rod Ejection 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

1. 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 ftW 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 using the smaller volume.

m. 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 CR dose assessment using a smaller volume of 200,000 ft3 is more conservative than that using the larger volume of 240,000 ft3 .
