-General Information CY-LA-170-301 Revision 6 Part II, Offsite Dose Calculation Manual This section reviews the offsite radiological limits applicable to the LaSalle Station and presents in detail the equations and procedures used to assess compliance with these limits. This calculational approach uses the methodology of NUREG-0133 (Reference 14), and incorporates certain simplifications such as the use of average meteorology.

4.1.1 Pre-calculated atmospheric transport parameters are based on historical average atmospheric conditions.

These historical meteorological conditions have resulted J.ci.i-l in the dispersion parameters shown in Table 4-2 through Table 4-6, and Table 4-I -z.o\'5 9 through Table 4-11. 4.1.2 The equations and parameters of this section are for use in calculating offsite radiation doses during routine operating conditions.

They are not for use in calculating doses due to non-routine releases (e.g., accident releases).

4.1.3 An overview of the required compliance is given in Table 1-1. The dose components are itemized and referenced, and an indication of their regulatory application is noted. Additionally, the locations of dose receivers for each dose component are given in Table 1-2. 4.1 .4 Airborne Release Point Classifications The pattern of dispersion of airborne releases is dependent on the height of the release point relative to adjacent structures.

Each release point is classified as one of the following three height-dependent types:

  • Stack (or Elevated)

Release Point (denoted by the letter Sor subscripts)

  • Ground Level Release Point (denoted by the letter G or subscript g)
  • Vent (or Mixed Mode) Release Point (denoted by the letter V or subscript v) 4.1 .5 Operability and Use of Gaseous Effluent Treatment Systems 1 OCFRSO Appendix I and ODCM Part I (RECS) require that the ventilation exhaust treatment system and the waste gas holdup system be used when projected offsite doses in 31 days, due to gaseous effluent releases, from each reactor unit, exceed any of the following limits:
  • 0.2 mrad to air from gamma radiation.
  • 0.4 mrad to air from beta radiation.

11.4-1 LASALLE ODCM PART II SECTION 4.doc CY *LA* 170-301 Revision 6 Part II, Offsite Dose Calculation Manual

  • 0.3 mrem to any organ of a member of the public.

z.e'? The station must project doses due to gaseous releases f ram the site at least once per 31 days. The calculational methods shown in sections 4.2.2.1 and 4.2.2.2 are used for this dose projection.

4.1 .6 For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. 4.2 Gaseous Effluents

zc,-:> To comply with this specification, gaseous effluent radiation monitors have setpoints corresponding to an offsite skin dose rate at or below the limit (see Part II Section 2.6). In addition, compliance is assessed by calculating offsite skin dose rate based on periodic samples obtained per station procedures.

4.2.1.3 Non-Noble Gas Radionuclides:

Organ Dose Rate RECS limits the dose rate to any organ, due to radioactive materials in gaseous effluents released from a site to areas at and beyond the site boundary, to less than or equal to a dose rate of 1500 mrem/yr (See Part I Section 12.4.1) Typically the adult is considered to be the limiting receptor in calculating dose rate to organs due to inhalation of non-noble gas radionuclides in gaseous effluents.

RECS requires the dose rate due to non-noble gas radioactive materials in airborne effluents be determined to be within the above limit in accordance with a sampling and analysis program specified in Part I Table R12.4.1-1.

The adult organ dose rate due to inhalation is calculated in each sector at the location of the highest offsite xJQ (see Table 4-3). The result for the sector with the highest organ inhalation dose rate is compared to the limit. 4.2.2 Time Averaged Dose from Noble Gas 4.2.2.1 Gamma Air Dose RECS limits the gamma air dose due to noble gas effluents released from each reactor unit to areas at and beyond the unrestricted area boundary to the following:

Beta air dose is calculated for the sector with the highest offsite (x/Q) and is compared with the RECS limit on beta air dose. For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. 4.2.2.3 Whole Body Dose The total (or whole) body dose, to any receiver is due, in part, to gamma radiation emitted from radioactivity in airborne effluents.

This component is added to others to demonstrate compliance to the requirements of 40CFR190 and 1 OCFR20. In accordance with NUREG 0133 Methodology, the total body dose component due to gamma radiation from noble gases released in gaseous effluents is calculated by the following expression:

Dre= 3.17E*08

  • t
  • D TB where: Dre is the total (or whole) body dose due to gamma radiation from noble gas radionuclides released in gaseous effluents (mrem) 3.17E-08 is a conversion constant (yr/sec).

t is the number of seconds in the period of interest (sec) Dre is the instantaneous dose rate to the total body due to radioactive materials (noble gasses) released in gaseous effluents from the site (mrem/yr)

The total body dose is also calculated for the 40CFR190 and 1 OCFR20 compliance assessments.

In some cases, the total body dose may be required in 1 OCFR50 Appendix I assessments (See Part II Table 1-1 ). 11.4-8 LASALLE ODCM PART II SECTION 4.doc CY-LA-170-301 Revision 6 Part 11, Offsite Dose Calculation Manual 4.2.2.4 Skin Dose

'2,o\-S There is no regulatory requirement to evaluate skin dose. However, this component is evaluated for reference as there is skin dose design objective contained in 1 OCFR50 Appendix I. Note that in the unlikely event that if beta air dose guideline is exceeded, then the skin dose will require evaluation.

In accordance with NUREG 0133 Methodology, the part of skin dose due to noble gases released in gaseous effluents is calculated by the following expression:

Dskln = 3.17E*08

  • t
  • D Skin where: Dskln is the skin dose due to beta and gamma radiation from noble gas radionuclides released in gaseous effluents (mrem) 3.17E*08 is a conversion constant (yr/sec).

t is the number of seconds in the period of interest (sec) D Skin is the instantaneous dose rate to the total body due to radioactive materials (noble gasses) released in gaseous effluents from the site (mrem/yr) 4.2.3 Time Averaged Dose from Non-Noble Gas Radionuclides RECS provides the following limits, based on 10CFR50 Appendix I, on the dose to a member of the public from specified non-noble gas radionuclides in gaseous effluents released f ram each reactor unit to areas at and beyond the unrestricted area boundary:

  • Less than or equal to 7.5 mrem to any organ during any calendar quarter
  • Less than or equal to 15 mrem to any organ during any calendar year The individual dose components are also required as part of the 40CFR190 assessments and combined as part of the 1 OCFR20 assessment (Part II Table 1-1 ). The dose due to radionuclides deposited on the ground is considered to be a component of the deep dose equivalent for 1 OCFR20 and 40CFR190 compliance and an organ (and total body) dose component for 1 OCFR50 Appendix I compliance.

The dose is calculated for releases in the time period under consideration.

11.4-9 LASALLE ODCM PART II SECTION 4.doc CY-LA-170-301 Revision 6 Part II, Offsite Dase Calculation Manual In accordance with NUREG-0133 methodology, time averaged dose from non noble gas radionuclides can be calculated using the following equation and the pathway specific "R" dose factor defined in the subsections below: Where: oNNG is the committed dose equivalent (COE) due to non noble gas radionuclides in gaseous effluents (mrem) 3.17E-08 is a conversion constant (yr/sec).

R1 is the dose factor for each identified radionuclide, i (m 2*mrem*sec/yr*µCi for (D/Q) calculations, or mrem*m 3/yr*µCi for (x/O) calculations)

W is the dispersion parameter for estimating the dose to an individual at the controlling location for long term (greater than 500 hr/yr) releases:

W = (x/O) for the inhalation pathway (sec/m 3) W = (D/Q) for the food and ground pathways (m" 2) a, is the release of radionuclides, radioactive materials in particulate form, and radionuclides other than noble gasses in gaseous effluents, i, for long term (greater than 500 hr/yr) releases (µCi). w is the dispersion parameter for estimating the dose to an individual at the controlling location for long term (equal to or less than 500 hr/yr) releases:

w = (x/q) for the inhalation pathway (sec/m 3) w = (D/q) for the food and ground pathways (m" 2) -q1 is the release of radionuclides, radioactive materials in particulate form, and radionuclides other than noble gasses in gaseous effluents, i, for short term (equal to or less than 500 hr/yr) releases (µCi). RECS Section 12.4.3, RSA 12.4.3.1, and Section 12.4.5, RSA 12.4.5.1 require cumulative and projected dose contributions for the current calendar quarter and the current calendar year for the specified non-noble gas radionuclides in airborne effluents to be determined at least once per 31 days. To comply with this specification, each nuclear power station obtains and analyzes samples in accordance with the radioactive gaseous waste or gaseous effluent sampling and analysis program in its RETS. For each organ of each age group considered (adult/teenager/child/infant), the dose for each pathway is calculated in every sector (except for sectors over water bodies). The calculation is based on the 11.4-10 LASALLE ODCM PART 11 SECTION 4.dac CY-LA-170-301 Revision 6 Part II, Offsite Dose Calculation Manual location assumptions discussed below in conjunction with the pathway equations.

For each organ of each age group, the doses are summed in each sector over all pathways.

The result for the sector with the highest total dose is compared to the limit. The values used for (X/Q) and (D/Q) are shown in Table 4-3 through Table 4-5 and correspond to the applicable pathway location.

For a release attributable to a processing or effluent system shared by more than one reactor, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. The dose evaluated is also included as part of the 10CFR20 and 40CFR190 assessment (See Part II Section 5). 4.2.3.1 Ground Plane The dose due to ground deposition of radioactivity is considered to be a total body dose component.

Dose due to the ground plane pathway can be calculated using the methodology described in 4.2.3 and the ground plane dose factor (RGi) defined below: RG 1 = K'*K"*SF*DFG1*(1-exp(-Ai*t))/A.1) where: RG1 is the ground plane dose factor for each identified radionuclide, i (m 2*mrem*sec/yr*µCi)

K' is a constant of unit conversion

= 1 E+06 (pCVµCi) K" is a constant of unit conversion

= 8760 (hr/yr) SF is the shielding factor (dimensionless)

DFG1 is the ground plane dose conversion factor for the ith radionuclide (mrem*m 3/hr*pCi) A.1 is the decay constant for the ith radionuclide (sec*1) t is the exposure time (sec) Note that ground plane dose factors are only given for the total body and no age group. Doses to other organs are assumed to be equal to the total body dose. All age groups are assumed to receive the same dose. 11.4-11 LASALLE ODCM PART II SECTION 4.doc CY -LA-170-301 Revision 6 Part 11, Offsite Dose Calculation Manual The deep dose equivalent (DOE) due to ground deposition is determined for each sector using the highest calculated offsite value of D/Q for that sector. The ground plane exposure pathway is considered to exist at all locations.

4.2.3.2 Inhalation The committed dose equivalent (COE) due to the inhalation pathway can be calculated using the methodology described in 4.2.3 and the inhalation dose factor (R 1 1) defined below: R 1 1 = K'*(BR)a*(DFA1)a where: R 1 1 is the inhalation dose factor for each identified radionuclide, i (mrem*m 3/yr*µCi) K' is a constant of unit conversion

= 1 E+06 (pCi/µCi) (BR)a is the breathing rate of the receptor age group (a) (m 3/yr) (DFA1)a is the organ inhalation dose factor for the receptor of age group (a) for the ith radionuclide (mrem/pCi)

The inhalation exposure pathway is considered to exist at all locations.

The CDE due to inhalation is determined for each sector using the highest calculated offsite value of X/Q for that sector. 4.2.3.3 Ingestion:

Vegetation Food ingestion pathway doses are calculated at locations indicated by the land use census survey. If no real pathway exists within 5 miles of the station, the cow-milk pathway is assumed to be located at 5 miles. Food pathway calculations are not made for sectors in which the offsite regions near the station are over bodies of water. Dose due to the vegetation ingestion pathway can be calculated using the methodology described in 4.2.3 and the vegetation dose factor (Rv1) defined below: Rv, = K'*[r/(Yv

If desired, more realistic parameters could be used in place of these to refine the estimate.

For example, one could determine whether the nearest resident really fishes the specified number of hours at the specified location.

Notes: a b c The amount of time in a year that a maximally exposed fisherman would spend fishing near the site is estimates as 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> per week for 8 months per year. This yields an estimate of: (months) (12 Hours) _8 .......... ( weeks) lzo11rs 52--=416--Week (months) year year 12--year Distance to nearest residence. (See Table 4-1) The OFk is the quotient of the number of hours a location is occupied and the number of hours in a year. Thus, OHk /8760 hours = OFk rounded to the nearest O.Q1 digit. In determining the maximally exposed individual, the following possibilities were considered:

the nearest resident, fisherman, and persons at the National Guard facility north of the site. The annual exposre time and .location of a maximally exposed fisherman were estimated on the basis of discussion with a member of the station staff. The nearest resident was found to have the greatest exposure to skyshine.

-General Information CY-LA-170-301 Revision 6 Part II, Offsite Dose Calculation Manual This section reviews the offsite radiological limits applicable to the LaSalle Station and presents in detail the equations and procedures used to assess compliance with these limits. This calculational approach uses the methodology of NUREG-0133 (Reference 14), and incorporates certain simplifications such as the use of average meteorology.

4.1.1 Pre-calculated atmospheric transport parameters are based on historical average atmospheric conditions.

These historical meteorological conditions have resulted J.ci.i-l in the dispersion parameters shown in Table 4-2 through Table 4-6, and Table 4-I -z.o\'5 9 through Table 4-11. 4.1.2 The equations and parameters of this section are for use in calculating offsite radiation doses during routine operating conditions.

They are not for use in calculating doses due to non-routine releases (e.g., accident releases).

4.1.3 An overview of the required compliance is given in Table 1-1. The dose components are itemized and referenced, and an indication of their regulatory application is noted. Additionally, the locations of dose receivers for each dose component are given in Table 1-2. 4.1 .4 Airborne Release Point Classifications The pattern of dispersion of airborne releases is dependent on the height of the release point relative to adjacent structures.

Each release point is classified as one of the following three height-dependent types:

  • Stack (or Elevated)

Release Point (denoted by the letter Sor subscripts)

  • Ground Level Release Point (denoted by the letter G or subscript g)
  • Vent (or Mixed Mode) Release Point (denoted by the letter V or subscript v) 4.1 .5 Operability and Use of Gaseous Effluent Treatment Systems 1 OCFRSO Appendix I and ODCM Part I (RECS) require that the ventilation exhaust treatment system and the waste gas holdup system be used when projected offsite doses in 31 days, due to gaseous effluent releases, from each reactor unit, exceed any of the following limits:
  • 0.2 mrad to air from gamma radiation.
  • 0.4 mrad to air from beta radiation.

11.4-1 LASALLE ODCM PART II SECTION 4.doc CY *LA* 170-301 Revision 6 Part II, Offsite Dose Calculation Manual

  • 0.3 mrem to any organ of a member of the public.

z.e'? The station must project doses due to gaseous releases f ram the site at least once per 31 days. The calculational methods shown in sections 4.2.2.1 and 4.2.2.2 are used for this dose projection.

4.1 .6 For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. 4.2 Gaseous Effluents

20' is the highest calculated annual average relative concentration for areas at or beyond the unrestricted area boundary for vent releases (sec/m 3). is the release rate of radionuclides, i, in gaseous effluents from all vent releases (µCi/sec).

RECS requires the dose rate due to non-noble gas radioactive materials in airborne effluents be determined to be within the above limit in accordance with a sampling and analysis program specified in Part I Table R12.4.1-1.

The adult organ dose rate due to inhalation is calculated in each sector at the location of the highest offsite xJQ (see Table 4-3). The result for the sector with the highest organ inhalation dose rate is compared to the limit. 4.2.2 Time Averaged Dose from Noble Gas 4.2.2.1 Gamma Air Dose RECS limits the gamma air dose due to noble gas effluents released from each reactor unit to areas at and beyond the unrestricted area boundary to the following:

Gamma air dose is calculated for the sector with the highest offsite (xf O) and is compared with the RECS limits on gamma air dose. For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. 4.2.2.2 Beta Air Dose RECS limits beta air dose due to noble gases in gaseous effluents released from each reactor unit to areas at and beyond the unrestricted area boundary to the following:

Beta air dose is calculated for the sector with the highest offsite (x/Q) and is compared with the RECS limit on beta air dose. For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. 4.2.2.3 Whole Body Dose The total (or whole) body dose, to any receiver is due, in part, to gamma radiation emitted from radioactivity in airborne effluents.

This component is added to others to demonstrate compliance to the requirements of 40CFR190 and 1 OCFR20. In accordance with NUREG 0133 Methodology, the total body dose component due to gamma radiation from noble gases released in gaseous effluents is calculated by the following expression:

Dre= 3.17E*08

  • t
  • D TB where: Dre is the total (or whole) body dose due to gamma radiation from noble gas radionuclides released in gaseous effluents (mrem) 3.17E-08 is a conversion constant (yr/sec).

The total body dose is also calculated for the 40CFR190 and 1 OCFR20 compliance assessments.

In some cases, the total body dose may be required in 1 OCFR50 Appendix I assessments (See Part II Table 1-1 ). 11.4-8 LASALLE ODCM PART II SECTION 4.doc CY-LA-170-301 Revision 6 Part 11, Offsite Dose Calculation Manual 4.2.2.4 Skin Dose

'2,o\-S There is no regulatory requirement to evaluate skin dose. However, this component is evaluated for reference as there is skin dose design objective contained in 1 OCFR50 Appendix I. Note that in the unlikely event that if beta air dose guideline is exceeded, then the skin dose will require evaluation.

In accordance with NUREG 0133 Methodology, the part of skin dose due to noble gases released in gaseous effluents is calculated by the following expression:

Dskln = 3.17E*08

  • t
  • D Skin where: Dskln is the skin dose due to beta and gamma radiation from noble gas radionuclides released in gaseous effluents (mrem) 3.17E*08 is a conversion constant (yr/sec).

t is the number of seconds in the period of interest (sec) D Skin is the instantaneous dose rate to the total body due to radioactive materials (noble gasses) released in gaseous effluents from the site (mrem/yr) 4.2.3 Time Averaged Dose from Non-Noble Gas Radionuclides RECS provides the following limits, based on 10CFR50 Appendix I, on the dose to a member of the public from specified non-noble gas radionuclides in gaseous effluents released f ram each reactor unit to areas at and beyond the unrestricted area boundary:

  • Less than or equal to 7.5 mrem to any organ during any calendar quarter
  • Less than or equal to 15 mrem to any organ during any calendar year The individual dose components are also required as part of the 40CFR190 assessments and combined as part of the 1 OCFR20 assessment (Part II Table 1-1 ). The dose due to radionuclides deposited on the ground is considered to be a component of the deep dose equivalent for 1 OCFR20 and 40CFR190 compliance and an organ (and total body) dose component for 1 OCFR50 Appendix I compliance.

The dose is calculated for releases in the time period under consideration.

11.4-9 LASALLE ODCM PART II SECTION 4.doc CY-LA-170-301 Revision 6 Part II, Offsite Dase Calculation Manual In accordance with NUREG-0133 methodology, time averaged dose from non noble gas radionuclides can be calculated using the following equation and the pathway specific "R" dose factor defined in the subsections below: Where: oNNG is the committed dose equivalent (COE) due to non noble gas radionuclides in gaseous effluents (mrem) 3.17E-08 is a conversion constant (yr/sec).

R1 is the dose factor for each identified radionuclide, i (m 2*mrem*sec/yr*µCi for (D/Q) calculations, or mrem*m 3/yr*µCi for (x/O) calculations)

W is the dispersion parameter for estimating the dose to an individual at the controlling location for long term (greater than 500 hr/yr) releases:

W = (x/O) for the inhalation pathway (sec/m 3) W = (D/Q) for the food and ground pathways (m" 2) a, is the release of radionuclides, radioactive materials in particulate form, and radionuclides other than noble gasses in gaseous effluents, i, for long term (greater than 500 hr/yr) releases (µCi). w is the dispersion parameter for estimating the dose to an individual at the controlling location for long term (equal to or less than 500 hr/yr) releases:

RECS Section 12.4.3, RSA 12.4.3.1, and Section 12.4.5, RSA 12.4.5.1 require cumulative and projected dose contributions for the current calendar quarter and the current calendar year for the specified non-noble gas radionuclides in airborne effluents to be determined at least once per 31 days. To comply with this specification, each nuclear power station obtains and analyzes samples in accordance with the radioactive gaseous waste or gaseous effluent sampling and analysis program in its RETS. For each organ of each age group considered (adult/teenager/child/infant), the dose for each pathway is calculated in every sector (except for sectors over water bodies). The calculation is based on the 11.4-10 LASALLE ODCM PART 11 SECTION 4.dac CY-LA-170-301 Revision 6 Part II, Offsite Dose Calculation Manual location assumptions discussed below in conjunction with the pathway equations.

For each organ of each age group, the doses are summed in each sector over all pathways.

The result for the sector with the highest total dose is compared to the limit. The values used for (X/Q) and (D/Q) are shown in Table 4-3 through Table 4-5 and correspond to the applicable pathway location.

For a release attributable to a processing or effluent system shared by more than one reactor, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. The dose evaluated is also included as part of the 10CFR20 and 40CFR190 assessment (See Part II Section 5). 4.2.3.1 Ground Plane The dose due to ground deposition of radioactivity is considered to be a total body dose component.

Doses to other organs are assumed to be equal to the total body dose. All age groups are assumed to receive the same dose. 11.4-11 LASALLE ODCM PART II SECTION 4.doc CY -LA-170-301 Revision 6 Part 11, Offsite Dose Calculation Manual The deep dose equivalent (DOE) due to ground deposition is determined for each sector using the highest calculated offsite value of D/Q for that sector. The ground plane exposure pathway is considered to exist at all locations.

4.2.3.2 Inhalation The committed dose equivalent (COE) due to the inhalation pathway can be calculated using the methodology described in 4.2.3 and the inhalation dose factor (R 1 1) defined below: R 1 1 = K'*(BR)a*(DFA1)a where: R 1 1 is the inhalation dose factor for each identified radionuclide, i (mrem*m 3/yr*µCi) K' is a constant of unit conversion

If no real pathway exists within 5 miles of the station, the cow-milk pathway is assumed to be located at 5 miles. Food pathway calculations are not made for sectors in which the offsite regions near the station are over bodies of water. Dose due to the vegetation ingestion pathway can be calculated using the methodology described in 4.2.3 and the vegetation dose factor (Rv1) defined below: Rv, = K'*[r/(Yv

Fishina 400 0.05 1.0 2100 Living at National Guard 2500 0.7 2400 Facility K = 2.28 E-5 mrem I (MWe-hr) These parameters are used to obtain an initial estimate of skyshine dose to the maximally exposed member of the public using ODCM Part 11, Section 5, Equation 5-1. If desired, more realistic parameters could be used in place of these to refine the estimate.

For example, one could determine whether the nearest resident really fishes the specified number of hours at the specified location.

Notes: a b c The amount of time in a year that a maximally exposed fisherman would spend fishing near the site is estimates as 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> per week for 8 months per year. This yields an estimate of: (months) (12 Hours) _8 .......... ( weeks) lzo11rs 52--=416--Week (months) year year 12--year Distance to nearest residence. (See Table 4-1) The OFk is the quotient of the number of hours a location is occupied and the number of hours in a year. Thus, OHk /8760 hours = OFk rounded to the nearest O.Q1 digit. In determining the maximally exposed individual, the following possibilities were considered:

the nearest resident, fisherman, and persons at the National Guard facility north of the site. The annual exposre time and .location of a maximally exposed fisherman were estimated on the basis of discussion with a member of the station staff. The nearest resident was found to have the greatest exposure to skyshine.
