1.0 INTRODUCTION

This Annual Radiological Effluent Release Report, for Fort Calhoun*Station Unit No. 1, is submitted as required by Technical*Specification 5.9.4.a for the period January 1, 2008 through December 31, 2008.1.1 Executive Summary The Radioactive Effluent Monitoring program for the year 2008 was conducted as described in the following report.* Major efforts were made to maintain the release of* radioactive effluents to the environment as low as*reasonably achievable.

The total gaseous activity released for 2008 was 3.78 curies.*This was an increase from the 2007 activity of 2.81 curies,*due to the 2008 refueling outage and limited gas decay tank space.* Dose contributions from gaseous effluents at theunrestricted area boundary were 1.98-03 mRad maximum*gamma air dose and 1.48E-03 mRad maximum beta air dose. This was an increase from the 2007 activity of 1.83E-*03 mRad and 1.24E-03 mRad, respectively.

Total activity (excluding tritium, dissolved gases, and alpha)released in 2008 in liquid effluents was 1.10E-02 curies.*This was an increase from the 2007 activity of 5.35E-03* curies due to the 2008 refueling outage.0 The total tritium activity released in 2008 in liquid effluents was 176.5 curies. This was an increase from the 2007* activity of 164.7 curies due to the 2008 refueling outage.0*The calculated whole body dose due to liquid effluents at the site discharge from all sources in 2008 was 2.39E-02 mRem. This was an increase from the 2007 dose* of 1.68E-02 mRem. The increase is attributed to the 2008*refueling outage.0 0 0l 0 0 0 0* -i1 0 O 0 0 0 The calculated critical organ dose due to liquid effluents at the site discharge from all sources in 2008 was 3.50E-02 mRem. This was an increase from the 2007 dose 0 of 2.01 E-02 mRem. The increase is attributed to the 2008 refueling outage.The Fort Calhoun Station meteorological system achieved a cumulative availability rate of 94.68% for the joint frequency parameters required by Regulatory Guide 1.23 of wind speed, wind direction, and delta temperature.

There were no abnormal releases during 2008. 0 During 2008 there was one change to the Offsite Dose Calculations Manual (ODCM) and no changes to the Process Control Program (PCP).For 2008, the total volume of buried solid radwaste was 70.12 cubic meters. This was a decrease from the 142.09 cubic meters of solid waste buried in 2007 due to *reduced waste shipments during 2008.The total buried activity for 2008 was 39.79 curies, 39.2 0 curies came from spent resin. This was an increase from the *2007 value of 12.94 curies due to higher curie loading of 0 stored spent resin.Overall, the radioactive effluent monitoring program was conducted in a manner to ensure the activity released and O associated dose to the public were maintained as low as O reasonably achievable.

0 2.2.2 Gaseous Effluents* The values specified in 10 CFR Part 20, Appendix B,* Column 1 are used as the ECL for gaseous radioactive

effluents released to unrestricted areas.* 2.3. Measurements and Approximations of Total Radioactivity 0 0 Measurements of total radioactivity in liquid and gaseous radioactive effluents were accomplished in accordance with the sampling and analysis requirements of Tables 3.1 and 3.2 of* Part I of the ODCM.* 2.3.1 Liquid Radioactive Effluents* Each batch was sampled and analyzed for gamma O emitting radionuclides using gamma spectroscopy, prior*to release. Composite samples were analyzed monthly* and quarterly for the Monitor and Hotel Waste Tanks.Composite samples were analyzed monthly in the onsite* laboratory for tritium and gross alpha radioactivity, using* liquid scintillation and proportional counting techniques

respectively.

Composite samples were analyzed* quarterly for Sr-89, Sr-90, and Fe-55 by a contract 1 0* 1-5 0 S S laboratory (Teledyne Brown Engineering).

A software program was used to project the total body and critical organ dose contribution atthe unrestricted area boundary for each release and the percent contribution to the annual objective dose.For continuous releases from the Steam Generator blowdown, daily grab samples were obtained for weekly, monthly and quarterly composites, in proportion to the rate of blowdown.

Samples were analyzed using gamma spectroscopy techniques weekly. Composites were also analyzed monthly in the onsite laboratory for tritium and gross alpha radioactivity using liquid scintillation and proportional counting techniques, respectively.

5 Composite samples were analyzed quarterly for Sr-89, Sr-90, and Fe-55 by a contract laboratory (Teledyne Brown Engineering).

S 2.3.2 Gaseous Radioactive Effluents Each gaseous batch release was sampled and analyzed for radioactivity prior to release. For release of Waste Gas Decay Tanks, noble gas grab samples were analyzed for gamma emitting radionuclides using gamma spectroscopy.

For releases from the Containment S Building, samples were taken using charcoal and S particulate filters, in addition to noble gas and Tritium grab samples, and analyzed for gamma emitting radionuclides prior to each release. The results of the analysis and the total volume of effluent released were used to determine the total amount of radioactivity released in the batch mode. A software program was developed and installed that can project the total body and critical organ dose contribution at the unrestricted area boundary for each release and the percent S contribution to the annual objective dose. This program also adds the projected dose to the current actual dose totals in a temporary file, until it is updated with actual release data at the completion of a purge.S Continuous release effluent pathways were continuously 5 sampled using charcoal and particulate filters and analyzed weekly for gamma emitting radionuclides using gamma spectroscopy.

Weekly particulate filters were analyzed for gross alpha radioactivity in the onsite 5 laboratory using proportional counting techniques.

1 S 1-6 5 S 0* Quarterly composites of particulate filters were analyzed for Sr-89 and Sr-90 by an offsite laboratory (Teledyne* Brown Engineering).

S 2.4 Estimation of Total Percent Error* The estimated total percent error is calculated as follows:* Total Percent Error =(El2 + E 2 2 + E 3 2 + En2)0.5 5 Where En = percent error associated with each contributing

parameter.

Sample counting error is estimated by the Canberra Genie System Software for samples analyzed by gamma*spectroscopy.

This calculation can include the error associated

with peak area determination, gamma ray abundance, efficiency

and half-life.

Systematic error is estimated for gaseous and liquid effluent analyses and dilution and wastewater volume.2.5 Batch Releases 0 A summary of information for liquid and gaseous batch releases is included in Table 111.1.* 2.6 Abnormal Releases Abnormal Releases are defined as unplanned and unmonitored

This data is available for review by the Nuclear Regulatory Commission upon request. Joint Frequency tables are included in Section VII, Attachment 2.Real time hourly meteorological data is used to calculate the annual air effluent dose to individuals.

For quarterly estimates during the year an annual average X/Q is used, which is an average of the highest X/Q's calculated for each of the previous two years.0 6.7 Assessment of Doses 6.7.1 Doses Due to Liquid Effluents 0 Total body, skin, and organ dose for liquid releases were calculated in mRem for all significant liquid pathways using the annual configuration of the LADTAP II program. The site discharge location was chosen to present a most conservative estimate of dose for an average adult, teenager, child and infant. A conservative approach is also presented by the assumption that Omaha and Council Bluffs receive all drinking water from the Missouri River.The LADTAP II program in its annual configuration was also used to calculate the total body and organ doses for the population of 853,274 within a 50-mile radius of the plant (based on the 2000 census). The results of the calculations are listed in Section V.The doses due to liquid effluents for total body and critical organ are also calculated quarterly using the methods in the ODCM. The results are listed in Section II.0 6.7.2 Doses Due to Gaseous Effluents Total body, skin and organ doses from ground releases were calculated in mRem to an average adult, teenager, child, and infant in each receptor using the annual 0 configuration of the GASPAR il program. Also, the doses to the same groups, in units of mRad due to gamma and beta radiation carried by air, were computed using GASPAR II.1 0 1-10 0 0 0* The GASPAR II program in its annual configuration was*also used to calculate the ALARA integrated population

dose summary for the total body, skin and organ doses in person-rem for all individuals within a 50-mile radius.The results of the calculations are shown in Section IV.*The doses due to gaseous effluents for total body*gamma and beta noble gas air dose are calculated quarterly using the methods in the ODCM with an annual average X/Q. The results are listed in Section II.0*6.7.3 Doses Due to 1-131, Tritium and Particulates with Half Lives Greater than 8 days.*The doses due to 1-131, Tritium and Particulates with half* lives greater than 8 days for total body and critical organ dose are calculated quarterly using the highest of infant or child dose factors and an annual average X/Q. The*results are listed in Section II for inhalation, ground and* food.6.7.4 Direct Radiation Dose to Individuals and Populations

Direct radiation doses attributed to the gamma radiation*emitted from the containment structure were not observed above local background at any TLD sample locations for this annual period.6.7.5 40 CFR 190 Dose Evaluation 0 ODCM Radiological Effluent Controls require dose evaluations to demonstrate compliance with 40 CFR Part*190 only if calculated yearly doses exceed two times the*annual design objectives for liquid and/or gaseous effluents.

At no time during 2008 were any of these limits exceeded; therefore, no evaluations were required.0 0 6.8 Groundwater Monitoring Program and Observations

OPPD conducted groundwater sampling from 15 wells and 2*surface water sites within the site property per NEI 07-07. One*well, MW-8, near a containment footing, had activity identified

from these analyses.

Activity was consistent with historical trends. To date, no groundwater pathway is present.S 0* I-11 0 S 0 0 S 0 0 0 0 S S 0 0 0 0 S 0 S 0 0 0 0 0 0 0 S 0 S S S S 0 SECTION II QUARTERLY DOSES FROM EFFLUENTS* Offsite Dose Calculation Manual January 1, 2008 -December 31, 2008 I1-1 Quarterly Dose Calculation Results 6 6 0 January 1, 2008 through December 31, 2008 0 0 With the implementation of the Fort Calhoun Station Radiological Effluent Technical Specifications (RETS) on October 1, 1985, radiation doses in the unrestricted area from liquid and gaseous effluents must be calculated on a quarterly basis in accordance with the Offsite Dose Calculation Manual (ODCM). These calculations are performed to ensure the annual S dose limits delineated in Appendix I of 10 CFR 50 and implemented by RETS are not exceeded.

If the results of the quarterly calculations exceed fifty percent (50%) of the annual limits of Appendix I, actions are taken to reduce effluents so that the resultant doses do not exceed the annual limits during the remainder of the year and a special report is submitted to the Nuclear Regulatory Commission.

No special reports were required for 2008 calculated doses.0 This section presents the results of the quarterly dose calculations performed during the period January 1, 2008 through December 31, 2008.Details are shown as to the types, sources and resultant doses from the -effluents, the annual limits and a comparison to the annual limits.0 0 0 0 0 0 0 0 0 0 0 0 0 0 11-2 0 0 FORT CALHOUN STATION CHEMISTRY FORM FC-421 R6 QUARTERLY CUMULATIVE DOSE CONTRIBUTION FROM RADIOACTIVE EFFLUENTS FORT CALHOUN FIRST QUARTER 2008 DOSE PROJECTIONS 0 0 S 0 0 0 0 0 0 0 0 0 0 0 0 0 0 I.

A. Potential Annual Doses to Individuals from Gaseous Releases* Total body, skin, and organ doses from ground releases were calculated in mRem to an average adult, teenager, child, and infant using the annual* configuration of the GASPAR II program. Results to each receptor are shown in* Tables IV-A-1 through IV-A-39. Also, the doses to the same groups,* Table IV-B-1, in units of mRad, due to gamma and beta radiation carried by air, were computed using GASPAR I1. In its annual configuration, GASPAR II assumes that all release rates are entered in curies per year (Ci/yr).* .The inputs to GASPAR Ii for the annual period from January 1, 2008 through December 31, 2008 were as follows:* (1) All gaseous effluents* (2) Entrained gases (Ar-41, Xe-131M, Xe-133M, Xe-133, Xe-135M, Xe-135, Kr-85M, Kr-87, and Kr-88) from liquid effluents.

(3) Annual X/Q at the actual receptor locations, which are corrected for open* terrain and plume depletion, are calculated according to Regulatory Guide 1.111. Also included are annual deposition rates corrected for the open terrain factor.* (4) The production, intake and grazing fractions were as follows: 1.0 for leafy* vegetables grown in garden of interest, 0.76 for produce grown in garden of interest, 0.5 for the pasture grazing season of the milk animal, 1.0 for* pasture grazing season of the meat animal, and 8 g/m 3 for the air water* (humidity) concentrations.

(5) All dose factors, transport times from receptor to individual, and usage factors are defined by Regulatory Guide 1.109 and NUREG-0172.

0* (6) Site specific information, within a five-mile radius of the plant, on types of* receptors located in each sector was used. That is, if a cow was not present in a sector, then the milk pathway for that sector was not considered.

If it was present, then the actual sector distance was used.0 0 0 0 0 0 0 0 V-0 6 O O These inputs introduce a most conservative approach for the following reasons: (1) The open terrain and deposition corrections increase annual X/Q by a O factor ranging between 1.0 and 4.0 (2) The production, intake, and grazing fractions, as defined in the input definition statement, represent the environment in an extremely conservative manner.O B. Potential Semiannual Doses to Population from Gaseous Releases The GASPAR II program in its annual configuration was also used to calculate

the ALARA integrated population dose summary for the total body, skin, and organ doses in man-rem for all individuals within a 50-mile radius.. The population-integrated dose is the summation of the dose received by all individuals and has units of man-thyroid-rem when applied to the summation of O thyroid doses. The same inputs were used as in the individual case with the O addition of the following:

(1) A total population of 853,274 (based on the 2000 census) was used to define the sector segments within a 50-mile radius of the plant. 0 O (2) Production of milk, meat, and vegetation is based on 1973 annual data for Nebraska as recommended by the Nuclear Regulatory Commission for use in GASPAR I1.0 0 0 0 0 0 0 0 O 0 0 0 O O 0 0 0 O IV-4 *O 0 TABLE IV-A-1 FORT CALHOUN ANNUAL 2008, DOSE PROJECTIONS SPECIAL LOCATION NO. 1 RES AT 4.36 MILES N ANNUAL BETAAIR DOSE = 1.96E-05 MILLRADS ANNUALGAMMAAIRDOSE

This represents 3.74E-02 percent of the 0 limits specified in Appendix B to 10 CFR 20 (1.0E-06 pCi/mL for unrestricted areas), 176.50 curies of tritium were discharged at an average diluted concentration of 1.57E-05 pCi/mL or 1.57 percent of ECL (1.OE-03 pCi/mL). Gross alpha radioactivity released during the reporting period total 2.01 E-04 curies. Off-site vendor reanalysis of 0 samples indicated that the reported concentration was attributed to short lived, naturally 0 occurring alpha emitters.Dilution water during the period amounted to 1."! 3E+12 liters, while liquid waste discharges consisted of 3.68E+06 liters of radioactive liquid waste and 1.47E+08 liters 0 of non-radioactive steam generator blowdown.0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 V-2 0 0 0 0 0 S A. Potential Annual Doses to Individuals from Liquid Releases*Total body, skin, and organ mRem for liquid releases were calculated for all*significant liquid pathways using the annual configuration of the LADTAP II program.*The inputs to LADTAP II for the annual period from January 1, 2008 through*December 31, 2008 were as follows:* (1) All liquid effluents were as described in Section IV except for entrained noble gases (Ar-41, Xe-131M, Xe-133M, Xe-133, Xe-135M, Xe-135,*Kr-85M, Kr-87, and Kr-88).(2) An average plant discharge rate of 641.1 cubic feet per second (CFS) was*utilized for 2008. The average discharge rate during releases was 435.52*cubic feet per second (CFS).(3) Dilution factors (inverse of the mixing ratios) were computed based on*Regulatory Guide 1.113 (equation 7 in Section 2.a.1 of Appendix A) for a*one dimensional transport model.(4) Drinking water transport times of 6.6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months to the Omaha intake and 7.0 hours0 days 0 hours 0 weeks 0 months to the Council Bluffs intake for the ALARA doses were used. A*transport time of 0.0 was used from the plant to the discharge site.(5) A shorewidth factor of 0.2 was used.* (6) All dose factors, transport times from receptor to individual, and usage*factors are defined by Regulatory Guide 1.109 and NUREG-0172.

The discharge site was chosen to present the most conservative estimate of* mRem dose for an average adult, teenager, child, and infant. A conservative

approach is also presented by the assumption that Omaha and Council Bluffs*receive all drinking water from the Missouri River.0 0 0 0 0 0 0 0 0 0 0* V-3 0 0 0 0 0 B.

The same input was used as in the individual cases with the addition of the following:

0 (1) Dilution factors and transport times for the pathways of sport fish, commercial fish, recreation and biota were calculated based on a distance of two miles downstream as approximately the distance to the nearest recreation facility -DeSoto National Wildlife Preserve.0 (2) The total fish harvest for both sport and commercial purposes was calculated using an average commercial fish catch for Nebraska.0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 V-4 0 0

The waste airborne radioactive material is treated in these gas decay tanks by holding for radioactive decay prior*to final controlled release to the environs.

In order to provide*conformance with the dose design objectives, gas decay tanks*are normally stored for approximately 30 days and thus achieve decay of short half-life radioactive materials, e.g., 1-131,*Xe-133. Earlier release is allowed when a plant need exists* and analytical results are in accordance with ALARA release*objectives.

If the radioactive airborne wastes from the gas decay tanks are discharged without processing in accordance

with the above conditions, and it is confirmed that one half of*the annual dose objective will be exceeded during the calendar*quarter, a special report shall be submitted to the Commission pursuant to Section 3.2.4A.* *b) Ventilation Exhaust Systems The radioactive effluents from the controlled access area of the*auxiliary building are filtered by the HEPA filters in the auxiliary*building ventilation system.

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 0 provisions of 40 CFR Part 190.11 and 10 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 0 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 10 CFR Part 50 will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR Part 20.1301.0 0 0 0 0 0 0 0 R19 0 0 0 S* FORT CALHOUN STATION CH-ODCM-0001

6.3.1 Monitoring Program 0 The radiological environmental monitoring program required by this* specification provides measurements of radiation and radioactive materials in* those exposure 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.

6.3.2 Land Use Survey 0 .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 best survey* information from door to door, aerial'or consulting with local agricultural authorities, or equivalent, shall be used. This survey satisfies the requirements of Section IV.B.3 of Appendix I to 10 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 2.0 For milk, the survey is restricted to only milk animals (cow or goat) producing* 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.

EFFLUENT MONITOR SETPOINTS 1.1 Liquid Effluents 0 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.

The flowrate for dilution water varies with the number of circulating water pumps in 0 service, the number of raw water pumps in service, and with the operation of the warm water recirculation.

Some warm water from the condenser outlet is diverted from the circulating water discharge to 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.

The concentration at the unrestricted area boundary, due to airborne effluent* releases, will be limited to less than Appendix B, Table 2, Column 1, values.* Radiation monitor alarm setpoints are established to ensure that these release limits are not exceeded.

In the event an airborne effluent release from the station result in an alarm setpoint being exceeded, an evaluation of the unrestricted area boundary* concentration resulting from the release will be performed:

0 To determine the concentration and air effluent concentration (aec) fraction summation at the unrestricted area boundary, the following equations will be used: 0 A, AK 0 Q,(XIQ)0 n A* andy <1 j= ECL, 0 Where:* Ai = Concentration of radionuclide (I) at the unrestricted area boundary* K 0 = Constant of unit conversion.

(1.OE-6 m 3/cc)ECLj = Effluent concentration limit (10 CFR Part 20, Appendix B, Table 2, Column 1 value for radionuclide(l))

SQ0 = The release rate of radionuclide (I) in airborne effluents from all* vent releases (in ýtCi/sec.)(y/Q) = Annual Average Dispersion Factor at the Unrestricted Area Boundary from ODCM Part II, Table 4 As appropriate, simultaneous releases from the Auxiliary Building'Ventilation Stack, Laboratory and Radwaste Building Stack and condenser off gas will be considered in evaluating compliance with the release rate limits of 10 CFR Part 20. 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.* 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 10 CFR Part 20 limits. Provided actual releases do not result in radiation* monitor indications exceeding alarm setpoint values based upon the above criteria,* no further analyses are required for demonstrating compliance with 10 CFR Part 20.R S* R19 0 0 6 FORT CALHOUN STATION CH-ODCM-0001 0 OFF-SITE DOSE CALCULATION MANUAL REFERENCE USE PAGE 83 OF 125 0 0 3. RADIOACTIVE EFFLUENT DOSE CALCULATIONS 3.1 Liquid Effluent Dose Calculations 0 Three pathways for human exposure to liquid releases from FCS to the Missouri River exists: 1) fish, 2) drinking water, and 3) Shoreline deposition.

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 4-29 and 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.0 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 the following limits: 0* during any calendar quarter<1.5 mrem to total body<5.0 mrem to any organ and 0* during any calendar year< 3.0 mrem to total body< 10.0 mrem to any organ Q0 The following calculational methods shall be used for determining the dose or dose commitment from liquid effluents.

LLD verifications will be performed on a periodic basis. This determination is to ensure that the counting system is able to detect levels of radiation at the LLD values for the specific type of analysis required.

They will be performed with a blank (non-radioactive) sample in the same counting geometry as the actual sample.R19 FORT CALHOUN STATION -OFF-SITE DOSE CALCULATION MANUAL REFERENCE USE CH-ODCM-0001 PAGE 99 OF 125 Table 2 -Dose Factors for Exposure to a Semi-Infinite Cloud of Noble Gases Nuclide P3-Air 1 13-Skin 2 (DFSi) y-Air 1 (Dfv) y-Body 2 (DFBi)Kr-83m 2.88E-04 --- 1.93E-05 7.56E-08 Kr-85m 1.97E-03 1.46E-03 1.23E-03 1.17E-03 Kr-85 1.95E-03 1.34E-03 1.72E-05 1.61 E-05 Kr-87 1.03E-02 9.73E-03 6.17E-03 5.92E-03 Kr-88 2.93E-03 2.37E-03 1.52E-02 1.47E-02 Kr-89 1.06E-02 1.01E-02 1.73E-02 1.66E-02 Kr-90 7.83E-03 7.29E-03 1.63E-02 1.56E-02 Xe-131m 1.11 E-03 4.67E-04 1.56E-04 9.15E-05 Xe-133m 1.48E-03 9.94E-04 3.27E-04 2.51 E-04 Xe-133 1.05E-03 3.06E-04 3.53E-04 2.94E-04 Xe-135m 7.39E-04 7.11 E-04 3.36E-03 3.12E-03 Xe-135 2.46E-03 1.86E-03 1.92E-03 1.81E-03 Xe-137 1.27E-02 1.22E-02 1.51 E-03 1.42E-03 Xe-138 4.75E-03 4.13E-03 9.21 E-03 8.83E-03 Ar-41 3.28E-03 2.69E-03 9.30E-03 8.84E-03 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 mrad- m 3 pCi -yr mrem -m3 pCi- r 3 2.88E- 04 = 2.88 x 10-4 R19 S S 0 0 0 S 0 0 0 0 0 0 6 0 0 0 0 0 0 0 FORT CALHOUN STATION OFF-SITE DOSE CALCULATION MANUAL REFERENCE USE CH-ODCM-0001 PAGE 100 OF 125 Table 3 -Bioaccumulation Factors (pCilkg per pCi/liter)

Meteorological Data Recovery Data availability from the on-site weather tower for the period January 1, 2008 through December 31, 2008 was less than the previous 12 months. The regulatory guide recovery was met with a cumulative recovery rate of 94.68% from the meteorological tower with the remaining 5.32% provided by the National Weather Service. The following table is a summary of the parameters and their respective recovery rates for the period.Hourly meteorological data used to replace missing tower data for the period January 1, 2008 through December 31, 2008 originated at Eppley Airfield Weather Station, a branch of the National Weather Service. The hourly data was treated in accordance with monthly correction factors and a proceduralized Pasquill-Turner transformation which utilizes solar angle, time of day, cloud cover, and wind speed to determine the Pasquill Class.0 The tabulations of the Weather Tower Data for the period January 1, 2008 through December 31, 2008 look appropriate for the season indicated.
