88 CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) 1.0 PURPOSE AND SCOPE 1.1 Purpose Page 6 of 134 Revision 27 1.1.1 Contains methodologies for and parameters necessary for calculating offsite doses, determination of gaseous and liquid radiation monitor set points, and administrative controls for effluent instrumentation, Radiological Effluent Tech Specs (RETS), and the Radiological Environmental Monitoring Program (REMP}. 1.2 Scope 1.2.1 Radioactive effluents are generated from station operations.

These controls provide methodologies ensuring these effluents are properly monitored and quantified to promote accurate dose reporting.

Additional controls ensure station equipment and processes are used to minimize release to the environment.

The combination of minimizing release, accurately reporting dose, and monitoring the plant environs provides the basis for ensuring that station operation is not negatively impacting public health and the environment.

CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) Page 7 of 134 Revision 27 2.7 Operable-Operability-A system, subsystem, train, component or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified safety function(s) and when all necessary attendant instrumentation, controls, nonnal or emergency electrical power sources, cooling and seal water, lubrication, and other auxiliary equipment that are required for the system, subsystem, train, component, or device to perform its specified safety function(s) are also capable of perfonning their related support function(s).

2.8 Purge-Purging

-PURGE or PURGING shall be any controlled process of discharging air or gas from a confinement to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is required to purify the confinement.

2.9 Residual

Radioactivity

-Residual radioactivity means radioactivity in structures, materials, soils, ground water, and other media at a site resulting from activities under the licensee's control. This includes radioactivity from all licensed and unlicensed sources used by the licensee, but it excludes background radiation.

It also includes radioactive materials remaining at the site as a result of routine or accidental releases of radioactive material at the site and previous burials at the site, even if those burials were made in accordance with the provisions of 10 CFR Part 20. 2.10 Site Boundary -The Site Boundary is the line beyond which the land is neither owned, or leased, nor controlled by the licensee.

2.11 Source Check -A SOURCE CHECK shall be the qualitative assessment of channel response when the channel sensor is exposed to a source of increased radioactivity.

2.12 Special Liquid -Non-routine release pathway in which normally non-radioactive liquid streams (such as Raw Water) found to contain radioactive material, are non-routine, and will be treated on a case specific basis if and when this occurs. 2.13 Unrestricted Area -An UNRESTRICTED AREA shall be any area at or beyond the SITE BOUNDARY access to which is not controlled by the licensee for purposes of protection of individuals from exposure to radiation and radioactive materials, or any area within the SITE BOUNDARY used for residential quarters or for industrial, commercial, institutional, and/or recreationa.1 purposes.

CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) 6.2.4 EPA 40 CFR Part 190 Reporting Requirements Page 56 of 134 Revision 27 With the calculated dose from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of dose from specifications 4.1.2A, 4.2.2A, or 4.2.3A, calculations shall be made including direct radiation calculations, to prepare and submit a special report to the Commission within 30 days and limit the subsequent releases such that the dose to any real individual from uranium fuel cycle sources is limited to s 25 mrem to the total body or any organ (except thyroid, which is limited to s 75 mrem) over the calendar year. This special report shall include an analysis which demonstrates that radiation exposures to any member of the public from uranium fuel cycle sources (including all effluent pathways and direct radiation) are less than the 40 CFR Part 190 standard.

Otherwise, obtain a variance from the Commission to permit releases which exceed the 40 CFR Part 190 standard.

The submittal of the report is to be considered a timely request and a variance is granted pending the final action on the variance request from the Commission.

6.2.5 ISFSI

10 CFR Part 72.104 Reporting Requirements The regulatory requirements of 10CFR20, 10CFR72 and 40CFR190 each limit total dose to individual members of the public without regard to specific pathways.

The only significant exposure pathways for light water reactors included in 10CFR20, 10CFR72 and 40CFR190 not addressed by 10CFR50 Appendix I are the direct radiation pathway and exposure from on-site activity by members of the public. The 10CFR72.104 dose limits are the same as those specified in 40CFR190.

ISFSI dose contribution is in the form of direct radiation as no liquid or gas releases are expected to occur. If the dose limits of 40CFR190 or 1OCFR72.104 are exceeded, a special report to the NRC, as well as an appropriate request for exemption/variance, is required to be submitted to the NRC. The requirement that the dose limits of 1OCFR72.104 apply to any 'real individual' is controlled for ISFSI activities in the ISFSI 72.212 report. Therefore, for the purposes of analyzing dose from the ISFSI, the member of the public as defined in 40CFR190 is the same as for the 'real individual'.

The report of the annual direct radiation required by 1 OCFR72 shall be submitted prior to 60 days from January 1 of each year. The external Total Body Dose is comprised of: 1) Total Body Dose due to noble gas radionuclides in gaseous effluents

2) Dose due to radioactive waste and the ISFSI CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) Page 57 of 134 Revision 27 3) Total Body Dose due to radioactivity deposited on the ground (this dose is accouhted for in the determination of the non-noble gas dose and is not considered here) The Total Body Dose, external is given by: D,ext = O,tb + D,osf WhereD,ext is the external dose D,tb is the total body dose D,osf is the .dose from on-site storage The Total Dose is then given .by: D,tot = D,ext + D,liq + D,nng Dose Limits Where D,tot is the total dose D,ext is the external dose P,liq is the dose from liquid effluents D,nng is the dose from non-noble gases Total Body, annual Thyroid, annual Other Qrgans, annual 25 mrem 75 mrem 25 mrem 6.3 Change Mechanism The Off-Site Dose Calcu.lation Manual is the controlling document for all radioactive effluent releases.

It Js defined as a procedure under the guidance of Technical Specification 5.8. It will be revised and reviewed by the Plant Operations Review Committee and approved by the Plant Manager in accordance with Technical Specification 5, 17. All changes to the Off-Site Dose Calculation Manual will be forwarded to the. Nuclear Regulatory Commission during the next reporting period for the Annual Radioactive Effluent Release Report in accordance with the requirements ofTechnical Specification 5.17.

CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) 6.4 Meteorological Data Page 58 of 134 Revision 27 The Annual Average x/Q is utilized to determine the concentrations of radionuclides at the unrestricted area boundary.

It is also the factor used in conjunction with the parameters and methodologies in Part II, of the Off-Site Dose Calculation Manual to determine unrestricted area dose on a quarterly bases or as needed. It is based on an average of the highest calculated sector xta values, using all 16 sectors for each of the three previous year Annual Radioactive Effluent Release Reports, and the XOQDOQ plume trajectory model. An additional 1 O percent will be added to the average for unrestricted area dose estimates performed quarterly or as needed for conservatism.

When calculating xta data for the Annual Radiological Effluent Release Report, if the highest calculated x/O for the reporting period is observed to be greater than +/- 10% of the Annual Average x/Q previously calculated, contact the -Supervisor-System Chemistry for further instructions.

This model conforms with the Nuclear Regulatory Commissions Regulatory Guide 1.111. Current year meteorological data will be utilized in the preparation of the Annual Radioactive Effluent Release Report. This data is used to calculate the joint frequency table, the dispersion coefficients and deposition factors in all 16 sectors. These are used in the calculation of doses to individuals in unrestricted areas as a result of the operation of Fort Calhoun Station. The models used, GASPAR 2 and LADTAP 2, meet the intent of Nuclear Regulatory Commissions Reg. Guide 1.109 and 1.21 for the reporting of doses due to routine radioactive effluent releases.

The Alarmn-rip setpoints for these instruments shall be calculated in accordance with Part II of the Offsite Dose Calculation Manual to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50. 7 .2 Radioactive Effluents 7 .2.1 Radioactive Liquid Effluents A. Concentration This specification is provided to ensure that the concentration of radioactive materials released in liquid waste effluents from the site to unrestricted areas will be less than 10 times the concentration levels specified in 10 CFR Part 20, Appendix 8, Table II, Column 2. This limitation provides additional assurance that the levels of radioactive materials iri bodies of water outside the site will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, and (2) the limits of 1 O CFR Part 20.1001-20.2401 to the population.

The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-133 is the controlling isotope and its effluent concentration in air (submersion) was converted to an equivalent concentration in water.

B. Dose Page 61 of 134 Revision 27 This specification is provided to implement the requirements of Sections II.A, Ill.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable".

Also, with fresh water sites with drinking water supplies which can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR Part 141. The dose calculation methodology and parameters in Part II of the Off-Site Dose Calculation Manual, implement the requirements in Section Ill.A that conformance with the guides of Appendix I is to be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated.

The equations specified in Part II of the Off-Site Dose Calculation Manual, for calculating the doses due to the actual release rates of radioactive material in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix l, 11 Revision 1, October 1977, and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977. C. Liquid Waste Treatment System The OPERABILITY of the liquid radwaste treatment system ensures that this system will be available for use Whenever liquid effluents require treatment prior to release to the environment.

The requirement that appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable".

This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix I to 10 CFR Part 50 and design objective and in Section 11.D of Appendix A to 10 CFR Part 50. The specified limits governing the use 9f appropriate portions of the liquid radwaste treatment system were specified to ensure the design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50 for liquid effluents are not exceeded.

D. Liquid Holdup Tanks Page 62 of 134 Revision 27 Restricting the quantity of radioactive material contained in the specified tanks provides assurance that in the event of an uncontrolled release of the tanks' contents, the resulting concentrations would be less than the limits of 10 CFR Part 20, Appendix B, Table II, Column 2, at the nearest potable water supply and the nearest surface water supply in an unrestricted area. 7.2.2 Radioactive Gaseous Effluents A. Concentration This specification, in conjunction with Steps 4.2.2A and 4.2.3A, is provided to ensure that the dose at or beyond the Site Boundary from gaseous effluents will be within the annual dose limits of 10 CFR Part 20 for MEMBERS OF THE PUBLIC. The release rate of radioactive material in airborne effluents shall be controlled such that the instantaneous concentrations for these radionuclides do not exceed the values specified in 10 CFR Part 20 for airborne effluents at the unrestricted area boundary.

To support plant operations, Supervisor-System Chemistry may increase this limit up to the limits specified in Technical Specifications 5.16.1.g.

Technical Specification 5.16.1.g.

establishes the administrative control limit on the concentration resulting from radioactive material, other than noble gases, released in gaseous effluents to unrestricted areas conforming to ten times 10 CFR Part 20.1001-20.2401, Appendix B, Table 2, Column 1. For noble gases, the concentration shall be limited to five times 10 CFR Part 20.1001-20.2401, Appendix B, Table 2, Column 1. Because these concentrations are applied on an instantaneous basis and because of the overriding 10 CFR Part 50 Appendix I cumulative dose limitations, these limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC either within or outside the Site Boundary, to annual average concentrations that would result in exceeding the annual total effective dose equivalent limit specified in 10 CFR Part 20.1301 (a).

The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I assure that the releases of radioactive material in gaseous effluents will be kept as low as is reasonably achievable.

The surveillance requirements implement the requirements in Section Ill.A of Appendix I that conform with the guides of Appendix I to be shown by calculational procedures based on models and data such that the actual exposure of an individual through the appropriate pathways is unlikely to be substantially underestimated.

The dose calculation methodology and parameters established in Part II of the Site Dose Calculation Manual, for calculating the doses due to actual release rates of radioactive noble gases in gaseous effluents are consistent with the methodology provided in Regulatory Guide 1.109, Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I, Revision 1, October 1977 and Regulatory Guide 1.111, Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors, Revision 1, July 1977.

Page 64 of 134 Revision 27 C. Dose 131, Radioactive Material in Particulate Form with Half-Lives Greater than Eight Days (Other than Noble Gases) and Tritium This specification is provided to implement the requirements of Sections 11.C, Ill.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition For Operation implements the guides set forth in Section 11.C of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I assure that the releases of radioactive material in gaseous effluents will be kept as low as is reasonably achievable.

The surveillance requirements implement the requirements in Section II I.A of Appendix I that conform with the guides of Appendix I to be shown by calculational procedures based on models and data such that the actual exposure of an individual through the appropriate pathways is unlikely to be substantially underestimated.

ihe dose calculation methodology and parameters established in Part II of the Site Calculation Manual, for calculating the doses due to actual release rates of radioactive noble gases in gaseous effluents are consistent with the methodology provided in Regulatory Guide 1.109, Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I, Revision 1, October 1977 and Regulatory Guide 1. 111, Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors, Revision 1, July 1977. The release rate specification for 1-131, radioactive material in particulate form with half-lives greater than eight days (other than noble gases) and tritium are dependent on the existing radionuclide pathways to man in the areas at or beyond the site boundary.

The pathways that were examined in the development of these calculations were: 1 ) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

D. Gaseous Waste Treatment Page 65 of 134 Revision 27 The OPERABILITY of the gaseous radwaste treatment system and the ventilation exhaust treatment systems ensures that the systems will be available for use whenever gaseous effluents require treatment prior to release to the environment.

The requirement that appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in gaseous effluents will be kept as low as is reasonably achievable.

This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix I to 1 O CFR Part 50 and design objective and in Section 11.D of Appendix A to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specifi~d to ensure the design objectives set forth in Section 11.B and 11.C of Appendix I, 10 CFR Part 50 for gaseous effluents are not exceeded.

E. Total Dose -Uranium Fuel Cycle Page 66 of 134 Revision 27 This specification is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 1 o CFR Part 20.1301 (d). This requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mRems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mRems. It is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the plant remains within twice the dose design objectives of Appendix I, 10 CFR Part 50, and if direct radiation doses (including outside storage tanks, etc.) are kept small. The Special Report shall describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered.

If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report, with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 1 O CFR Part 20.2203(a)(4) and 20.2203(b) is considered to be a timely request and fulfills the requirements 40 CFR Part 190 until NRC staff action is completed.

The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle. Demonstration of compliance with the limits of 40 CFR Part 190 or with the design objectives of Appendix I to 1 O CFR Part 50 will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR Part 20.1301.

CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) 7 .3 Radiological Environmental Monitoring 7 .3.1 Monitoring Program Page 67 of 134 Revision 27 The radiological environmental monitoring program required by this specification provides measurements of radiation and radioactive materials in those e>eposure pathways and for radionuclides which lead to the highest potential radiation exposures of individuals resulting from the station operation.

This monitoring program thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways.

The initially specified monitoring program was effective for at least the first three years of commercial operation.

Following this period, program changes are initiated based on operational experience.

7.3.'2 Land Use Survey This specification is provided to -ensure that changes in the use of unrestricted areas are identified and that modifications to the monitoring program are made if required by the results of this survey. The frequency of the Land Use Survey has been reduce-0 to a biennial requirement in site procedures because persons knowledgeable in land use census monitor usage characteristics perform routine REMP sampling, This approach allows knowledge gained during sample collect{on to be integrated into the program, maintaining its effectiveness.

The best survey informatjon from door to door, aerial or consulting with local agricultural authorities, or equivalent, shall be 1.1sed. This survey satisfies the req1.1irements of $ectio11 IV.B.3 <>f Appendix I to 1 O CFR Part 50. Restricting the survey to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used, 1) that 20% of the garden was used for growing broad leaf vegetation (i.e.; similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/m 2* For milk, the survey is restricted to only milk animals (cow or goat) procjucing milk for human consumption.

Air monitoring stations are strategically located to monitor the resident receptors who could potentially receive the highest doses from airborne radioactive material.

For groundwater, samples Shall be taken when sources are determined to potentially be affected by plant operations, and when sources are tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination.

Guidance provided in the Branch Technical Position and Technical Specification 5.16.2 is used to meet the intent of NUREG-1301.

CH-ODCM-0001 Reference Use Off-Site Dose Calculation Manual (ODCM) 7.3.3 lnterlaboratory Comparison Program Page 68 of 134 Revision 27 The requirement for participation in an lnterlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of a quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid for the purposes of Section IV.8.2 of Appendix I to 1 O CFR Part 50. 7.4 Abnormal Release or Abnormal Discharge Reporting

7.4.1 Specific

information should be reported concerning abnormal (airborne and/or liquid) releases on site and abnormal discharges to the unrestricted area. The report should describe each event in a way that would enable the NRC to adequately understand how the material was released and if there was a discharge to the unrestricted area. The report should describe the potential impact on the ingestion exposure pathway involving surface water and ground water, as applicable.

The report should also describe the impact (if any) on other affected exposure pathways (e.g., inhalation from pond evaporation).

7.4.2 The following are the thresholds for reporting abnormal releases and abnormal discharges in the supplemental information section: A. Abnormal release or Abnormal Discharges that are voluntarily reported to local authorities under NEI 07-07, Industry Ground Water Protection Initiative.

Abnormal release or Abnormal discharges estimated to exceed 100 gallons of radioactive liquid where the presence of licensed radioactive material is positively identified (either in the on-site environs or in the source of the leak or spill) as greater than the minimum detectable activity for the laboratory instrumentation.

C. Abnormal releases to on-site areas that result in detectable residual radioactivity after remediation.

D. Abnormal releases that result in a high effluent radiation alarm without an anticipated trip occurring.

E. Abnormal discharges to an unrestricted area.

1.1 Liquid

Effluents Page 71 of 134 Revision 27 1.1.1 There are two liquid discharge pathways to the Missouri River. These pathways originate with the radioactive liquid waste processing system (monitor or hotel tanks) and the steam generator blowdown system. Both of these pathways empty into the circulating water system which discharges to the Missouri River (see Figure 1 ). Figure 2 depicts the liquid discharge pathways and associated radiation monitors.

Figure 3 depicts the methods of liquid effluent treatment.

1. 1.2 The flowrate for dilution water varies with the number of circulating water pumps in service, the number of raw water pumps in service, and with tile operation of the warm water recirculation.

Some warm water from the condenser outlet is diverted from the circulating water discharge t9 upstream of the intake structure to help prevent ice from forming on the circulating water pump intakes during winter months. The varying dilution flowrate and utilization of warm water recirculation is accounted for in the dilution calculations for monitor tank and stream generation releases.

1.1.3 Technical

Specification 5.16.1.b establishes the administrative control limit on concentration of radioactive material, other than dissolved or entrained noble gases, released in liquid effluents to unrestricted areas conforming to ten times 10 CFR Part 20.1001-20.2401, Appendix 8, Table 2, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2.0 E-04 µCi/ml total activity.

1.1.4 The liquid effluent monitoring instrumentation ALERT setpoints shall be established low enough to ensure that the concentration of radioactive material released in liquid effluents at site discharge will be less than the concentrations specified in 10 CFR Part 20, Appendix 8, Table 2, Column 2. 1.1.5 The liquid effluent monitoring instrumentation HIGH ALARM setpoints shall be established low enough to ensure that the concentration of radioactive material released in liquid effluents at site discharge will be less than 10 times the concentrations specified in 10 CFR Part 20, Appendix 8, Table 2, Column 2. 1.1.6 Cs-137 is used to calibrate the liquid effluent monitors.

1.1. 7 Liquid Effluent Radiation Monitors A. Steam Generator Slowdown Monitors (RM-054A and B) 1. These process radiation detectors monitor the flow through the steam generator blowdown lines and automatically close the blowdown isolation valves if the monitor high alarm setpoint is reached. The monitor controls liquid effluent releases so that 10 times the 10 CFR Part 20 limit at the unrestricted area boundary of 1.0E-06 µCi/cc, is not exceeded at the site discharge.

2. The following calculations for maximum concentration and alarm setpoints are valid for simultaneous radioactive liquid releases of steam generator blowdown and monitor tank discharge.

3. The maximum allowable concentration in the blowdown line is calculated as follows: (1.0E -05µCi/ml)(F)

CMAX = f Where: 1.0E-05 µCi/ml = Ten times 10 CFR Part 20 Limit for unidentified radionuclides at site discharge (1 O CFR Part 20, Appendix B, Note 2).

An airborne radioactive waste flow diagram with the applicable, associated radiation monitoring instrumentation and controls is presented as Figure 4. The airborne waste disposal system is presented in Figure 5.

Auxiliary Building -The Auxiliary Building Exhaust Stack receives discharges from the waste gas decay tanks, containment purge, containment vent systems and the auxiliary building ventilation system. Radiation Monitor RM-062 provides noble gas monitoring and iodine and particulate sampling for the Auxiliary Building Exhaust Stack. Backup noble gas mpnitoring and iodine and particulate sampling is provided by RM-052. Ventilation Isolation Actuation Signal {VIAS) is actuated by exceeding a monitor's alarm setpoint.

Actuation of VIAS will isolate releases from containment and waste gas decay tanks. The Auxiliary Building Exhaust fans will remain in operation.

Laboratory and Radioactive Waste Processing Building (LRWPB)-Noble gas monitoring and particulate and iodine sampling is provided by RM-043. This radiation monitor/sampler does not serve a control function. (

Condenser Off-Gas Monitors -Noble gas activity is monitored by RM-057. The condenser off-gas is discharged directly to the environment.

Exceeding the high alarm setpoint on RM-057 will activate isolation of main steam to the Auxiliary Steam System. Technical Specification 5.16.1.g.

1. Either of these monitors may be used to measure the noble gas activity in the exhaust stack. The noble gas is monitored after passing through a particulate filter, and charcoal cartridge.

The monitor controls airborne releases so that five times the 10 CFR Part 20 limit at the unrestricted area boundary of 5.0E-07 µCi/cc, based upon Xe-133, is not exceeded.

The Ventilation Isolation Actuation Signal is initiated when the high alarm setpoint is reached. 2. The following calculations for maximum release rate and alarm setpoint are valid for simultaneous airborne releases from Auxiliary Building Exhaust Stack, Condenser Off-gas and the LRWPB Exhaust Stack. 3.

Monitor indications (readings) may be averaged over a time period not to exceed 15 minutes when determining noble gas release rate based on correlation of the monitor reading and monitor sensitivity.

Historical annual average dispersion parameters, as presented in 'Table 4, may be used for evaluating the airborne effluent dose rate. 2.2.4 For administrative purposes, more conservative alarm setpoints than those as prescribed above may be imposed. However, conditions exceeding those more limiting alarm setpoints do not necessarily indicate radioactive material release rates exceeding 1 O CFR Part 20 limits.

Fish are considered to be taken from the vicinity of the plant discharge.

The drinking water for Omaha is located 19 miles downstream from FCS. The dilution factors for these pathways are derived from the Revised

Environmental Report for FCS, (1974), (page 4-2e c;1nd 4-31'). This report *states that during Low-Low river conditions, the concentration at Omaha's water intake will be ::,14% of the concentration at discharge from FCS and will average 3%. This equates to a dilution factor of 7.14, which is used to calculate the maximum dose to an individual from liquid pathways and a dilution factor of 33.33, for calculating the average dose. All pathways combine to give the dose to an individual in unrestricted areas. 3.1.2 10 CFR Part 50, Appendix I restricts the dose to individuals in the unrestricted areas from radioactive materials in liquid effluents from the Fort Calhoun Station to th.e following limits:
