Purpose The purpose of this calculation is to document the logic and assumptions used in choosing the Emergency Action Level (EAL) threshold values for Containment Radiation Monitor Readings corresponding to a Loss of the Reactor Coolant System Fission Product Barrier.

Background

To support the implementation of NEI 99-01 Revision 4 methodology for development of Emergency Action Levels for Exelon stations, it was deemed beneficial to provide additional technical documentation describing the methodology for determining the containment radiation monitor values indicating a loss of the RCS barrier.

The generic guidance provided in NEI 99-01, Revision 4 is not intended to be used by plants as is. The generic guidance is intended to give the logic for developing site-specific IC/EALs (Section 5.3 of NEI 99-01). Plant specific wording and values must be developed. If specific guidance provided in NEI 99-01 Revision 4 cannot be used as presented, documentation must be provided to show how Exelon Corporation implemented the intent of the guidance.

Discussion The Loss of the RCS Fission Product Barrier as indicated by Containment Radiation Monitoring NEI 99-0 1 Revision 4 provides the following guidance:

The (site-specific) reading is a value which indicates the release of reactor coolant to the containment. The reading should be calculated assuming the instantaneous release and dispersal of the reactor coolant noble gas and iodine inventory associated with normal operating concentrations (i.e., within T/S) into the containment atmosphere. This reading will be less than that specified for Fuel Clad Barrier EAL #5. Thus, this EAL would be indicative of an RCS leak only. If the radiation monitor reading increased to that specified by Fuel Clad Barrier EAL #5, fuel damage would also be indicated.

However, if the site specific physical location of the containment radiation monitor is such that radiation from a cloud of released RCS gases could not be distinguished from radiation from nearby piping and components containing elevated reactor coolant activity, this EAL should be omitted and other site specific indications of RCS leakage substituted.

EP-EAL-06 1 1, Rev 1 Page 3 of 4 Calculations were performed to estimate the containment radiation dose rates resulting in a release of all the RCS inventory to the containment atmosphere with the Maximum Technical Specification coolant activity. See Attachment 1 (B WR) and Attachment 2 (PWR) for all assumptions and calculation results.

EP-EAL-06 1 1, Rev 1 Page 1 BWR Assumptions:

RCS Liquid and Free-Air volumes were obtained from the BWR Core Damage Assessment Model (CDAM) Requirements Specification:

o Mid-Atlantic Version 1.1, Section 7.2.2, Normal System Volumes o Mid-West Version l.O/l.l, Section 7.2.2 Normal System Volumes with the following exceptions:

o None It is assumed the entire Liquid RCS volume is instantaneously released to the Drywell and all entrained Iodine immediately disperses homogeneously throughout the free air space.

Only the Drywell volumes are used in the calculation. Although some of the released material may ultimately find its way into other areas such as the Suppression Pool air volumes, it is assumed the initial release will be confined to only the Drywell space.

The RCS Dose Equivalent 1-131 values of interest (0.2 uCi/gm and 4.0 uCi) were obtained from the sites Technical Specifications and were specifically requested by the Revision 4 EAL implementation team for this calculation. These are standard Technical Specification values for Boiling Water Reactors.

Only isotopes of Iodine were used in the calculation. Although noble gasses will be released to the containment atmosphere, their dose rate contribution is small compared to that of the Iodines because noble gasses in a BWR are only contained within the steam space of the RCS and are continuously being off-gassed. As such, the calculated dose rate will be conservative.

Dose Conversion factors used to calculate Isotopic Concentrations were obtained from FGR 11. Though these factors are for Alternative Source Term (AST) calculations, when normalized to I-13 1 they adequately represent the mixture of Iodines in the coolant. The Dose Conversion Factors from FGR 11 were obtained from Table 2.1, column Effective. The choice of using values from the Effective column was based on the methodology used for AST calculations and section 4.1.2 of Regulator Guide 1.183 which states:

The exposure-to-CEDE factor for inhalation of radioactive material should be derived from data provided in ICRP Publication 30, Limits for Intakes of radionuclides by Workers (Ref. 19). Table 2.1 of Federal

EP-EAL-06 1 1, Rev 1 Page 2 Guidance Report 11, Limiting values of Radionuclide Intake and Air Concentration and Dose Conversion factors for Inhalation, Submersion, and Ingestion (Ref. 20), provides tables of conversion factors acceptable to the NRC staff. The factors in the column headed Efective yield doses corresponding to the CEDE.

Since only the Normalized ratios are used in the calculation, unit conversion is not required, however the international units of SvBq were converted to RedCi for ease of understanding.

Additional calculations were performed using the FGR 1 1 Table 2.1, column Thyroid Dose Conversion Factors for comparison purposes. The calculations were limited to the 4.0 uCi/gm DEI-13 1 values. The results of these calculations are included in the Results table at the end of this attachment.

Microshield Model:

A generic approach was taken when constructing the MicroShield model since each sites actual configuration is different. Even though the entire free air space volume is available for dilution of the released radioactive isotopes, the radiation detectors located within the drywell are not exposed to the entire volume. Therefore a cylindrical source representing the entire drywell was not used. Instead, a box was constructed in the Microshield model that approximates the size of the area that a detector would be exposed to. The box measured 20 feet in depth (distance from the vessel support wall to the drywell wall), 40 feet tall, and 40 feet wide.

Forty feet square is considered a reasonable representation of the free air space around the detector. A dose receptor point, representing the detector, was placed on the outer edge of the box (representing the drywell wall) halfway up and across the box. This best represents the location of a radiation detector within the drywell mounted on the outer or inner wall.

No attempt was made to simulate shielding from components within the drywell nor was any credit taken for backscatter from the surrounding walls or components. The box was then filled with the calculated isotopic concentrations to determine a dose rate at the given point.

Methodology:

Microshield requires a given concentration in uCi/cc or uCi/gm for each isotope of interest. To obtain those concentrations requires converting the I-13 1 Dose Equivalent concentration (0.2 uCi/gm and 4.0 uCi/gm) to their individual isotopic components. In this case an equivalent for I-131,I-132,I-133,I-134 and 1-135.

Individual calculation sheets, Microshield runs and supporting documents are included in this attachment for reference purposes for each site. The following provides an explanation of the calculations performed.

EP-EAL-06 1 1, Rev 1 Page 3 Normalized I-13 1 Equivalent Activity Distribution A normalized I-13 1 equivalent activity distribution for each isotope was calculated using the relative mix of the isotopes of interest for each facility.

These ratios vary from site to site and are listed on the individual sites calculation spreadsheets. Copies of the source documents are contained within this calculation. The normalized value is calculated using the following equation:

Where:

DCF(i) = Isotopes FGR-11 Dose Conversion Factor (See Assumptions for details)

DCF(1-131) = 1-131 FGR-11 Dose Conversion Factor (See Assumptions for details)

NDCF(i) = The Isotopes ratio normalized to the I-13 1 DCF.

Since only the normalized DCF values are used in the calculation, no unit conversion is necessary.

The second is based on assumptions considered ta provide a realistic conservative estimate of the radiological consequences. This analysis is referred to as the "realistic analysis".

A schematic of the release path is shown in Figure 15.6.4-1.

'l5.6.4.5.1 Desinn Basis Analysis The design basis analysis is based on NRC Standard Review Plan 15.6.4 and NRC Regulatory Guide 1.5. The specific models, assumptions and the program used for computer evaluation are described in Reference 2. Specific values of parameters used in the evaluation are presented in Table 15.6.4-2.

15.6.4.5.1.1 Fission Product Release from Fuel There is no fuel damage as a result of this accident. The only activity available for release from the break is that which is present in the reactor coolant and steam lines prior to the break. This level of activity is consistent with an offgas release rate of IOU pCilsec - M W T after 30 minutes delay (approximately 300,000 pCilsec). The iodine concentrations in the reactor coolant are three times the design basis concentrations which are given by (FCilgrn):

The MStlV detection and closure time of 5.5 sec results in a discharge of 42,500 lb of steam and 53,750 lb of liquid from the break, The mass release is limited by choked flow through the main steam line flow restrictors and the MSLIV closure time, Neither of the limitations are power related, so the mass refease is applicabfe at both the original and current ficensed power. Assuming ail the activity in this discharge becomes airborne, the release of activity to the environment is presented in Table 15.6.4-3.

DRESDEN - UFSM Rev. 5 January 2003 The MCHFR throughout the transient was calculated using a digital computer code. The code calculates the thermal hydraulic response of a single nuclear reactor coolant channel, consisting of an array of cylindrical he1 rods surrounded by channel walls. The code includes provisions for pressure losses, fluid expansion, inlet flow variations, axial power shape, and various heat transfer modes. The MCHFR throughout the transient was calculated fur the case OE normal ac power available and the degraded case of simultaneous loss of normal ac power, which would cause a recirculation pump trip. The core flowrates both with and without recirculation pumps were calculated using the five-node digital computer code used to calculate internal forces. These results atre shown on Figure 55.6-3 which includes the sweep time of the core. The calculated hZCHFII.

wodd not go below 2.0 (figure 15.6-3) throughout the transient even if the isolation valves were closed at the longest time; therefore, core integrity is maintained throughout the accident and no fuel I damage should result. (MCHFR has been replaced in later analyses by MCPR. Since these quantities are not interchangeable, the terminology in this analysis has not been revised.)

15.6.43 Radiolorzical Conseauences The following section describes main steam line break radiological dose analysis performed for t.he initial licensing of the plant, i.e., 1x7 fuel arrays.

The predominant activity in the discharged coolant would be N-16, which would be significantly reduced by decay due to its short half-life (about 7 seconds). If the reactor contained fuel with cladding leaks, the water released through the break would contain some fission products.

During 1964, the Dresden Unit 1 reactor was operated with a significant number of cladding leaks.

Analysis of reactor water samples indicated the following yearIy average ission product contents:

for computer evaluation are described in Reference 4. Specific values of parameters used in the evaluation are presented in Table 15.6-5.

3-135 There is no fuel damage as a result of this event. The only activity available for release from the break is that which is present in the reactor coalant and steamlines prior to the break. The iodine concentration in the reactor coolant is then given by (pCilgm):

0.390 1-131 I

0.039 1-132 0.360 Because of i t s short half-life, N-16 is not considered in the analysis.

The transpart pathway is a direct, unfiltered release to the stearn tunnel, which is a part of the secondary containment. The MSZV detection and closure time of 5.5 seconds results in a discharge of 14,000 pounds of steam and 86,000 pounds of liquid from the break, Assuming all the activity in this discharge becomes airborne, the release of activity to the environment is presented in Table 15.6-6.

This level of activity is consistent with an uff-gas release rate of 300,000 pCilsec after a 30-minute delay.

The calculated exposures for the design-basis analysis are presented in Table 15.6-8 and are a small fraction of the guidelines of 10 CFR 100.

Realistic Analysis The realistic analysis is based an a plausible but still conservative assessment of this event. The specific models and assumptions and the program used for computer evaluation are described in Reference 2. Specific values of parameters used in the evaluation are presented in Table 15.6-5.

Since there is no fuel rod damage as a consequence af this event, the only activity released to the environment is that associated with the steam and liquid discharged from the break.

The activity released from the event; is a function of the coolant activity, valve closure time, and mass of coolant released. A portion of the released coolant exists as steam prior to the blowdown, and as such does not contain the same concentration per unit of mass as does the steam generated as a consequence of the blowdawn. Therefore, it is necessary to subtract the initial steam mass from the 15.6-12 REV. 13

LGS UFSAR 15.6.4.5.1 Design Basis Analysis The design basis analysis is based on SRP 15.6.4 and Regulatory Guide 1.5.

The specific models and assumptions and the program used for computer evaluation are described in Section 15.10.

Specific values of parameters used in the evaluation are presented in Table 15.6-9.

The only activity released from the reactor vessel is that contained in the coolant as a result of normal operation.

The integrated mass leaving the RPV through the steam line break is 108,785 lb, including 20,452 lb in the initial steam that existed prior to the blowdown.

All activity in the discharge becomes airborne. It is assumed that an equilibrium coolant concentration consistent with a 30 minute offgas release rate of 0.35 Ci/sec exists prior to the accident.

Although there will be some activation and corrosion products released, the isotopes of primary importance are the iodine isotopes. The iodine isotopes and noble gas activity released from the break and to the environment prior to isolation valve closure time are presented in Table 15.6-10.

The iodine concentration in the reactor coolant is given below:

ACTIVITY ISOTOPE 1-131 1-132 1-133 1-134 1-135 0.420 0.3115 0.84 0.455 Because of its short half-life, N-16 is not considered in the analysis.

15.6.4.5.2 Realistic Analysis This information has not been updated to reflect updated to reflect the current licensing design basis. The information should be used for historical reference only and not to support the design basis of the plant.

The realistic analysis is based on a realistic but still conservative assessment of this accident. The specific models and assumptions and the program used for computer evaluation are described in Reference 15.6-3. Specific values of parameters used in the evaluation are presented in Table 15.6-9. The leakage path used in these calculations is shown in Figure 15.6-2.

Using the most probable operating condition prior to the postulated break and realistic assumptions, the calculated mixture level in the RPV does not reach the steam line before isolation is complete.

Therefore, only steam will issue from the break during the entire transient. The total integrated mass leaving the break is 37,548 15.6-11 Rev. 11 9/02 I

1) Average of Minimum and Maximum from referenced calculation A. Volume Corrections A volume correction is necessary whenever a single sample is taken and the two locations (Reactor Coolant and Containment Sump) are not in a state of equilibrium (when the released activity is not assumed to be spread throughout both sample locations). The volume correction is as follows:

Volume Sampled Location Volume 60th Locations 7.2.3 Pressu re/Tem Derature Correction The pressure/temperature correction is applied to gaseous samples and is used to account for differences between system pressure and temperature, and sample pressure and temperature. The pressure/temperature correction is as f 01 lows:

PBAPS After the MSIV's close (10.5 sec), depressurization stops and natural convection is established through the reactor core. No fuel cladding perforation occurs even if the stored thermal energy in the fuel were simply redistributed while natural convection is being established; cladding temperature would be about l,OOO°F, well below the temperatures at which cladding can fail. Thus, it is concluded that even for a 10.5-sec MSIV closure, fuel rod perforations due to high temperature do not occur. For shorter valve closure times, the accident is less severe. After the MSIV's are closed, the reactor can be cooled by operation of any of the normal or standby cooling systems.

Reference 14.6.18 shows that adequate core cooling can be accomplished with no high pressure injection, manual initiation of ADS 10 minutes after MSIV closure, and either LPCI or Core Spray injection. The core flow and MCHFR during the first 10.5 sec of the accident are shown in Figures 14.6.17 and 14.6.18.

Since the MCHFR never drops below 1.0, the core is always cooled by very effective nucleate boiling.

14.6.5.2 Radioactive Material Release (See note at the beginning of Section 14.6.5.)

I 14.6.5.2.1 Assumptions The following assumptions are used in the calculation of the quantity and types of radioactive material released from the nuclear system process barriers outside the secondary containment.

1.

The amounts of steam and liquid discharged are as calculated from the analysis of the nuclear system transient.

2.

The concentration of biologically significant radionuclides contained in the coolant are as follows and are based on an off-gas release rate of 0.35 Ci/sec:

Iodine 131 Iodine 132 Iodine 133 Iodine 134 Iodine 135 0.17 pCi/cc 1.02 pci/cc 1.04 pCi/cc 1.47 pCi/cc 1.30 pCi/cc Because the steam-to-water halogen concentration ratio is on the order of 3 x lQ-5(8), only the halogens carried out of the reactor vessel by the liquid phase during the discharge of the steam-water mixture are significant. Because the coolant activity contents are based on data derived from reactor operation with an unusually large number of cladding failures, and because high normal stack gas discharge rate is assumed, considerable conservatism is inserted into the analysis.

UFSAR 15'6. $5 Radiological C onseque ncc s The fullowing describes main steam line break radiological dose analyses performed for the initial licensing of the plant, ia., 7x7 fuel arrays.

The predominant activity in the discharged coolant would be N-16, which would be significantly reduced by decay due to its short half-life (about 7 seconds). If the reactor contained fuel with cladding leaks, the water released through the break would contain some fission products. [15.6-18]

During 1964 the Dresden Unit 1 reactor was operated with a significant number of cladding leaks. Analysis of reactor water sample8 indicated the following yearly average fission product content:

Activity Fission Product i i k Cilcc)

I-13 2 0.025 I-133 0.1 Other halogens 0.25 Other fission products 0.25 With a separate reactor cleanup system for each unit, it is estimated that the maximum coolant activity would be approximately 2.3 pCilcc at 100,000 pCi/s release rate, and would have the following fission product contents:

Fission Product 1-132 I-133 1-134 Other halogens Other fission products 1-131 1-135 Activity 0.067 0.38 0.40 0.53 0.49 0.14 0.28 IpCilcc)

Measurements of halogen concentrations in the Dresden Unit 1 reactor water and condensate showed that the steam to water halogen concentration ratio was in the range of 3 x fO'3 to 1 x 10'". The only halogens carried out through the break would therefore be those absorbed in the water, Thus, 116 curies, including 3.4 curies of 1-131, 19.1 curies of 1-132, 20.2 curies of1-33, 27.0 curies of 1-134, and 24.9 curies of 1-135 would be carried out through the break.

Based on operating experience, the above fission product concentrations in the reactor coolant would occur when the off-gas emission was at about 100,000 pCi/s measured after 30 minutes decay in the off-gas system. The noble gas activity discharged from the break, assuming a l U. 5 seconds MSfV closure time, would be 5.4 Ci (calculated for 2 minutes decay time).

EP-EAL-0611, Rev 1 Page 1 PWR Assumptions:

RCS Liquid and Free-Air volumes were obtained from the PWR Core Damage Assessment Model (CDAM) Requirements Specification o Mid-Atlantic Version 1.O, Section 7.2.2, Sample Volume Calculations and Corrections o Mid-West Version 1.0, Section 7.2.2 Sample Volume Calculations and Corrections with the following exceptions:

o None It is assumed the entire Liquid RCS volume is instantaneously released to the Containment volume and all entrained Iodine and Noble Gas immediately disperses homogeneously throughout the free air space.

Free Air Volumes are as described in the CDAM documentation included in this calculation.

The RCS Dose Equivalent 1-131 values of interest (0.35 uCi/gm and 60.0 uCi/gm) were obtained from the sites Technical Specifications and were specifically requested by the Revision 4 EAL implementation team for this calculation. These are standard Technical Specification values for Pressurized Water Reactors.

Isotopes of Iodine and Noble Gas were used in the calculation. Unlike BWRs, which are constantly degassing, a considerable amount of Noble Gas is entrained within the Reactor Coolant that will be released to the free air volume upon depressurization. RCS Noble Gas concentrations are based on 1% failed fuel and will remain constant despite changes in the Dose Equivalent Iodine values Dose Conversion factors used to calculate Isotopic Concentrations were obtained from FGR 11. Though these factors are for Alternative Source Term (AST) calculations, when normalized to 1-13 1 they adequately represent the mixture of Iodines in the coolant. The Dose Conversion Factors from FGR 11 were obtained from Table 2.1, column Effective. The choice of using values from the Effective column was based on the methodology used for AST calculations and section 4.1.2 of Regulator Guide 1.183 which states:

EP-EAL-06 1 1, Rev 1 Page 2 The exposure-to-CEDE factor for inhalation of radioactive material should be derived from data provided in ICRP Publication 30, Limits for Intakes of radionuclides by Workers (Ref. 19). Table 2.1 of Federal Guidance Report 1 1, Limiting values of Radionuclide Intake and Air Concentration and Dose Conversion factors for Inhalation, Submersion, and Ingestion (Ref. 20), provides tables of conversion factors acceptable to the NRC staff. The factors in the column headed EJScective yield doses corresponding to the CEDE.

Since only the Nomalized ratios are used in the calculation, unit conversion is not required, however the international units of Sv/Bq were converted to RedCi for ease of understanding.

Additional calculations were performed using the FGR 1 1 Table 2.1, column Thyroid Dose Conversion Factors for comparison purposes. The calculations were limited to the 60.0 uCi/gm DEI-13 1 values. The results of these calculations are included in the Results table at the end of this attachment.

Microshield Model:

A generic approach was taken when constructing the Microshield model since each sites actual configuration is different. Even though the entire air space volume is available for dilution of the released radioactive isotopes, the radiation detectors located within the containment are not exposed to the entire volume. Therefore a cylindrical source representing the entire containment was not used. Instead, a box was constructed in the Microshield model that approximates the size of the area that a detector would be exposed to. The box measured 30 feet in depth (distance from the mounted wall to the closest significant wall), 40 feet tall, and 40 feet wide. A dose receptor point, representing the detector, was placed on the outer edge of the wall halfway up and across the box.

This best represents the location of a radiation detector within the containment mounted on a wall. No attempt was made to simulate shielding from components within the containment nor was any credit taken for backscatter from the surrounding walls or components. The box was then filled with the calculated isotopic concentrations to determine a dose rate at the given point.

Me thodology :

Microshield requires a given concentration in uCi/cc or uCi/gm for each isotope of interest. To obtain those concentrations requires converting the given I-13 1 Dose Equivalent concentration (0.35 uCi/cc and 60.0 uCi/cc) to their individual isotopes components. In this case an equivalent for I-13 1, I-132, I-133, I-134 and I-135. Noble Gas concentrations are independent of I-13 1 Dose Equivalent Concentrations and were calculated with a different methodology then Iodines.

EP-EAL-06 1 1, Rev 1 Page 3 Iodine Conversion Calculations Normalized I-13 1 Equivalent Activity Distribution A normalized I-13 1 equivalent activity distribution for each isotope was calculated using the relative mix of the isotopes of interest for each facility.

These ratios vary from site to site and are listed on the individual spreadsheets.

Copies of the source documents are contained within this calculation. The normalized value is calculated using the following equation:

Where:

DCF(i) = Isotopes FGR-1 1 Dose Conversion Factor (See Assumptions for details)

DCF(1-131) = 1-13 1 FGR-11 Dose Conversion Factor (See Assumptions for details)

NDCF(i) = The Isotopes ratio normalized to I-13 1.

Since only the normalized DCF values are used in the calculation, no unit conversion is necessary.

US. NUCLEAR REGULATORY COMMISSION SPR aGb REGULATORY GUIDE July 2000 OFFICE OF NUCLEAR REGULATORY RESEARCH REGULATORY GUIDE 1.183 (Draft was issued as DG-1081)

ALTERNATIVE RADIOLOGICAL SOURCE TERMS FOR EVALUATING DESIGN BASIS ACCIDENTS AT NUCLEAR POWER REACTORS Regulatory guides are issued to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRCs regulations, techniques used by the staff in evaluating specific problems or postulated accidents, and data needed by the NRC staff in its review of applications for permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions different from those set out in the guides will be acceptable if they provide a basis for the findings requisite to the issuance or continuance of a permit or license by the Commission.

This guide was issued after consideration of comments received from the public. Comments and suggestions for improvements in these guides are encouraged at all times, and guides will be revised, as appropriate, to accommodate comments and to reflect new information or experience. Written comments may be submitted to the Rules and Directives Branch, ADM, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001,

Regulatory guides are issued in ten broad divisions: 1, Power Reactors; 2, Research and Test Reactors: 3, Fuels and Materials Facilities; 4, Environmental and Siting; 5, Materials and Plant Protection: 6, Products: 7, Transportation; 8, Occupational Health; 9, Antitrust and Financial Review; and 10, General.

Single copies of regulatory guides (which may be reproduced) may be obtained free of charge by writing the Distribution Services Section, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, or by fax to (301)415-2289, or by email to DISTRlBUTlONQNRC.GOV. Electronic copies of this guide are available on the internet at NRCs home page at <WWW.NRC.GOV> in the Reference Library under Regulatory Guides and through the Electronic Reading Room, as Accession Number ML003716792, along with other recently issued guides, at the same web site.

i 3.6 Fuel Damage in Non-LOCA DBAs The amount of fuel damage caused by non-LOCA design basis events should be analyzed to determine, for the case resulting in the highest radioactivity release, the fraction of the fuel that reaches or exceeds the initiation temperature of fuel melt and the fraction of fuel elements for which the fuel clad is breached. Although the NRC staff has traditionally relied upon the departure from nucleate boiling ratio (DNBR) as a fuel damage criterion, licensees may propose other methods to the NRC staff, such as those based upon enthalpy deposition, for estimating fuel damage for the purpose of establishing radioactivity releases.

The amount of fuel damage caused by a FHA is addressed in Appendix B of this guide.

DOSE CALCULATIONAL METHODOLOGY The NRC staff has determined that there is an implied synergy between the ASTs and total effective dose equivalent (TEDE) criteria, and between the TID-14844 source terms and the whole body and thyroid dose criteria, and therefore, they do not expect to allow the TEDE criteria to be used with TD-14844 calculated results. The guidance of this section applies to all dose calculations performed with an AST pursuant to 10 CFR 50.67. Certain selective implementations may not require dose calculations as described in Regulatory Position 1.3 of this guide.

4.1, Offsite Dose Consequences The following assumptions should be used in determining the TEDE for persons located at or beyond the boundary of the exclusion area (EAB):

4.1.1 The dose calculations should determine the TEDE. TEDE is the sum of the committed effective dose equivalent (CEDE) from inhalation and the deep dose equivalent (DDE) from external exposure. The calculation of these two components of the TEDE should consider all radionuclides, including progeny from the decay of parent radionuclides, that are significant with regard to dose consequences and the released radioactivity. l3 4.1.2 The exposure-to-CEDE factors for inhalation of radioactive material should be derived from the data provided in ICRP Publication 30, Limits for Intakes of Radionuclides by Workers (Ref. 19). Table 2.1 of Federal Guidance Report 1 1, Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation, Submersion, and Ingestion (Ref. 20), provides tables of conversion factors acceptable to the NRC staff. The factors in the column headed effective yield doses corresponding to the CEDE.

4.1.3 For the first 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, the breathing rate of persons offsite should be assumed to be 3.5 x lo-cubic meters per second. From 8 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following the accident, the breathing rate should be assumed to be 1.8 x l 0-4 cubic meters per second. After that and until the end of the accident, the rate should be assumed to be 2.3 x cubic meters per second.

l3 The prior practice of basing inhalation exposure on only radioiodine and not including radioiodine in external exposure calculations is not consistent with the definition of TEDE and the characteristics of the revised source term.
