1.0 INTRODUCTION

This Annual Radiological Effluent Release Report; for Fort Calhoun Station Unit No. 1; is submitted as required by Technical Specificaticm 5.9.4.a for the perlod January 1, 2017 through December 31, 2017. 1. 1 Executive Summary The Radioactive Effluent Monitoring program for the year 2017 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 airborne activity released from noble gas was 1.88 E-4 curies. This was a decrease from the 2016 activity of 1,,04 curies. This decrease was due to decrease in RCS source from plant shutdown. The total airborne activity from 1-131, 1-133, and particulates with half.-lives > 8 days in 2017 was 0.00 curies. This is a continuation from the 2016 activity of 0.00 curies. This remained constant from .2016. The total airborne ;activity from Tritium was 0.393 curies. This was a decrease from the 2016 activity of 2.99 curi.es. This decrease was dµe to not performing containment purges for c:iefueling actMtie$.

The total airborne activity from C-14 was 0.00 curies. This was the decrease from 2016 levels of 1.97 curies. Airborne activity from C-14 is included in the 2017 annual report, per Regulatory Guide 1 ;21, Re\liSion

2. This is a calculated value based on power generation and days of operation.

Critical organ doses from C-14 were calculated using a rati.o of 15% as CO2. This ratio was determined during an NRC in-plant *source term study conducted at ttle Fort Calhoun Station o.etween 1916 and t977, NUR~G/CR-0140. Sinc.e Fort Calhoun Station ceased power operations, C-14 is no longer being produ~d. Any C-14 rel~ased fn;>rrtgasJanks or decommissioning activities Wa$ previously accounted .for hi reports which had power history. Dose contributions from airborne effluents at the unrestricted area boundary were; 1.13E-09 mRad gamma air dose, 1.28E .. 07 mRad beta air dose, 5.47E-04 mRem total body dose, and 5.47E-04 mRem critical organ dose. Gamm.a and beta dose showed a decrease from 2016 levels of 1.28 E-'03 mRad gamma air dose and 5.70-.04 mRad beta air dose, from not re-leasing iodines and a 1-1 reduction in gas source term due to plant shutdown. Whole body and critical organ doses decreased from 2016 levels. of 8.68E-02 mRem total body dose and 4.20E-01 mRem critical organ dose. This decrease is attributed to the gas source term reduction previously mentioned. Total-water activity (excluding tritium, dissolved gases, and a*lpha) released in 2017 in. liquid effluents was 2.23E-03 curies. This was a decrease from the 2016 activity of 4.34E-02. curies. This decrease was due to a substantial decrease in liquid Waste generated and reduced source term from cessation of operations. The total water tritium activity released in 2017 in liquid effluents was 2.2 curies. This was a de.crease from the 2016 activity of 149 curies. This decreas_e was due to a sLJbstantlal decrease in liquid waste generated and reduced source term *trom cessation of operations, The calculated whole body dose due to liquid effluents at the site discharge from .all sources in 2017 was 2.80E-01 mRem which was 9.3-3% of the annual dose limit This was an. increase from the 2016 dose of 2 .. 11--01 mRem, which was 7,03% ofthe annual dose limit. Dose increased despite a significant decrease in volume and activity released. Since cessation of operations, dilution flow has decreased from a range t20,000-36Q,OOO gpm to 7200 gprn. Station procedures lin,it release flow rates, qt these lower dilution levels. The combinat_ion of lower flow and decreased dilutipn represents an increase ih coilcentratiohs being rel.eased offsite, The calculated critical organ dose due to liquid effluents at the site discharge from all sources in 2017 was 4.39E-01 mRem. This was an increase from the-2016 dose of 3.26E-01 mRem. This increase was previously described. The Fort Calhoun Station meteorological system had a cumulative recovery rate of 96A7% from the $talion meteorological tovver with th~ remaioing 3.,53% provided by the N~tionql W~att,er Service, for the joint frequency parameters required by Regulatory $uide 1.23 for wind speed, wirid qirection,.and delta temperature. There were no abnormal releases during 2017. During 2017 there were two changes to the Off-'site. Dose Calculations Manual (ODCM}, GH-ODCM-0001 and one change to the Process Control Program; RP-5101 .. For 2017, the total volume of solid radwaste released from the unit was 260.24 cubic meters. This was a increase from the 69.04 cubic meters of solid waste released from the unit in 20t6. The increase was attributed to thirteen shipments made in 2017 and two shipments in 2016. The total activity released from the unit for 2017 was 212.18 curies, 212.09 curies from spent resin, 7.93E-02 curies from dry compressables, and *8.11 E-03 curies from other. This Was an increase from the 2016 value of 2.16E..:02 curies. Overall, the effluent monitoring program was conducted in a manner to ensure the activity released and dose to the public were maintained as low as reasonably achievable; 2.0 SUPPLEMENTAL INFORMATION 2.1 Regulatory Limits The ODCM Radiological Effluent Control Specifications applicable to the release of radioactive material in liquid and gaseous effluents are described in the following sections. 2.1.1 Fission and Activation Gases, (Noble Gases) The release rate of radioactive material in airborne effluents shall be controlled such that the instantaneous conce.ntrations of radionuclides do not exceed the values specified

in 10 CFR 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 Specification 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, releas.ed in gaseous effluents to unrestricted areas conforming to ten times 10 CFR 20.1001-20.2401, Appendix 8, Table 2, Column 1.

The do.se to an individual or dose commitment to any organ of an individual in unrestricted areas due to the releas.e of 1-131, 1-133, C-14, H-3, and radioactive material in particulate form with half-lives greater than eight days .(other than noble gases) in airborne effluents shall not exceed 7.5 millirem from all exposure pathways during any calendar quarter. b. The dose to an individual or dose commitment to any organ of art individual. in unrestricted areas due to the reiease of 1-131, 1-133, 0-14, H-3, and radioactive materials in particulate form with half-lives greater than eight days (other than noble gases) in airborne effluents shall not exceed 15 millirem from. all exposure pathways during any .calendar year. 2.1.3 Liquid' Effluents The release rate of radioactive material. in liquid effluents shall be controlled such that the instantaneous concentrations for racJionuclides, other than dissolved or entrained noble gases, do not exceed the values specified in 10 CFR 20 for liquid effluents at site discharge. To support plant operations, the Supervisor -System Chemistry may increase this limit up to the limit specified in Technical Specifications 5.16.1.b. 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 20.1001-20.2401, Appendix B, Table 2, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-04 µCi/ml total activity. 1-4 The dose or qose commitment to a MEMBER OFTHE PUBLIC from radio~ctive materials in liquid eff11Jents released to.unrestricted areas $hall be limited to: a. During any calendar quarter: Less than or equal to 1.5 mReni to the whole body and less than or equal to 5 mRem to any organ.and b, During any calendar year: Less than or 'equal to 3 mRem to the whole body and less than or equal to 10 mRem tQ any organ.

2.1 .. 4 Total Dose-Uranium Fuel Cycle The dose to any individual from uranium fuel cycle *sources shall be limited* to s 25 mRem to the total body or any org~n (except thethyroid, which shall be limited to S.75 mRem) during each calendar year. 2.2 Effluent Concentration Limits (ECL) 2.2. 1 Liquid Effluents The values specified in 10 CFR Part 20, Appendix B, Column 2 are used as the ECL for liquid radioactive effluents released .fo.unrestricted areas. A value of2.0E-04

µCi/ml is .used as the EGL for dis.solvect and entrained noble. gases in liquid effluents. 2.2.2 Gaseous Effluents The values specified in 10 CFR Part 20, Appendix B, Column 1 a.re used as the ECL for gase6u$ radio~cti.ve effluents released to unrestricted areas. 2.3 Measurements .and Approximations of Total Radioactivity 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. 1-5 2.3.1 Liquid Radioactive Effluents E'.ach batch was sampled and analyzed for gamma emitting radionuclides using gamma spectroscopy, prior to release. Composite samples were analyzed monthly and quarterly for the Monitor 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, Fe-55, Ni-'63, and Gross Alpha by a contract laboratory (Teledyne Brown Engineering, Inc.). A software program was used to project the total body and critical organ dose contribution at the unrestricted area boundary for each release and the percent contribution to the annual objective dose. There were no releases from the Steam Generator blowdown during the reporting period. 2.3.2 Gaseous Radioactive Effluents Each gaseous batch release was sampled ~nd analyzed for radioactivity prior to release.. For release of Waste Gas Decay Tanks, noble gas grab*samples were analyzed for garnnia emitting radionuclides using gamma spectroscopy. 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 :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. Continuous release effluent pathways were continuously 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 laboratory using proportional counting techniques. Quarterly composites of particulate filters were analyzed for Sr-89, Sr-90, and Gross Alpha by a contract laboratory (Teledyne Brown Engineering, Inc.).

1-6 2.4 Estimation of Total Percent Error The estimated total percent error is calculated as follows: Total Percent Error = (E1 2 + E2 2 + E3 2 + ... + En 2)o.s Where En= percent error associated with each contributing parameter.

Sample counting error is estim~ted 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 A summary of information for liquid and gaseous batch releas~s is included in Table 111.1. 2.6 Abnormal Releases Abnormal Releases are defined as unplanned and unmonitored releases of radioactive material from the site. A summary of information for liquid and gaseous abnormal releases is included in Table 111.2. 3.0 GASEOUS EFFLUENTS The quantities of radioactive material released in gaseous effluents are summarized in Tables 111.3, 111.4 and 111.5. All radioactive materials released in gaseous form are considered to be ground level releases. 4.0 LIQUID EFFLUENTS The quantities of radioactive material released in liquid effluents are summarized in Tables 111.6; 111.7 and 111.8.

5,0 SOLID WASTES The quantities of radioactive material released as .solid effluents are summarized in Section VL 1-7 6.0 RELATED INFORMATION 6.1 Operabiiity of Liquid and Gaseous Monitoring Instrumentation During the reporting period there was 1 instrument used to monitor radioactive effluent releases that failed to meet the minimum reportable instrument operability requirements listed in the ODCM during the reporting period. RM-063, Post Accident Radiation Monitor, was inoperable for 1.00 days {9/22/2017-12/31/2017) due to a failure of a circuit board. Multiple attempts to obtain new and modified boards did not address the issue. The al:)ility to perform grab sampling per CH-SMP-PA-0005 in the event of an emergency was the required compensatory action during the monitor's unavailability.

6.2 Changes to the Offsite Dose Calculation Manual (ODCM) and/or Process Control Program (PCP) During 2017, two revisions were made to the ODCM and one change made to the PCP.

The following changes were made to the ODCM: o Added annual reporting methodology for the total dose as required by 10 CFR 72.104. o Revised the vegetation sampling location as determined by the 2016 Land Use Survey. o Removed reference to Technical Specifications 5.18 to ODCM Implementing Step 6.2.1 D, since Technical Specification was deleted. o Added twelve new TLD locations to allow for better tracking of dose to members of the general public to ensure compliance with 40 CFR 190.
The following change was made to the PCP: o The document number was revised from RW-AA-100, Process Control Program for Radioactive Wastes, to RP-5101, Process Control Program for Radioactive Wastes. o The format was revised, but the content remained unchanged.

Detailed documentation concerning the evaluations and corrective actions is maintained onsite; 6.4.1 Abnormal Gaseous and Liquid Releases Ne;> abnormal releases were made during the cc1lendar year of 2017. 6.4.2 Failure to Meet Specified Sampling Requirements During 2017, there were no instances in which specifie:d sampling requirements were not met. 6.5 Modifications to Liquid and Gaseous Waste Treatment and Ventilation Exhaust Systems During the reporting period no design modifications were approved nor implemented involving major changes to the Liquid and Gaseous Waste Treatment Systems.
1-9 6.6 Meteorological Monitoring Program A summary of hourly meteorological data, collected during 2017, is retained onsite and is maintained as documentation as required by Regulatory Guide 1.21 Rev 2. 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. 6. 7 Assessment of Doses 6. 7 .1 Doses Due to Liquid Effluents 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 950,006 within a 50-mile radius of the plant {based on the 2010 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. 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 configuration of the GASPAR II 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. The GASPAR II program in its annual configuration was also used to calculate the ALARA integrated population dose 1-10 summary for the total body, skin and organ doses in rem for all indivicluals within c1 50-mile radius. The results ,of the calculations are sh.own in Sectipn IV. The doses due to gaseous effluents for total body gamrna 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. 6.7.3 Doses Due to 1-131, h-133, C-14; H-.3, and Particulates with Half Lives Gr~ater than 8 days. The doses due to 1-131,.1-133, C-14, H-3, arid Particuiates with half.,lives greater than 8 days f<;>r tots.I pody ancJ 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 ~ackground ~t any TLD ,sample locations for this annualperiod.

6. 7 .5 40 CFR 190 Dose Evaluation ODCM Radiological Effluent Controls require dose evaluations and a special report 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 201'7 were ;:my of these lirnits exceeqed; therefore, no special report per Tech Specification 5.16 was required. 1-11 The external Total Body Dose is comprised of: t) Total Body Dose due to noble gas radionuclides in gaseous effluents

2) Dose dt,ie to radio.active waste and the ISFSI 3) Total Body Dose due to radioactivity deposited on the ground (this dose is accounted for in the determfnation of the non-noble gas dose and is not considered here) The Total Body Dose, external is given by: Oext = Dtb + Dosf Where Dext is the external dose Dtb i~ the total pody dpse t>osf is the .dose from on.site storage The Total Dose is then given by: Dtot = Dext + Dliq + Dnng Where Dtot is the total dose Dext is the external dose DHq i~ the d.ose from liquid effluents Dnng is the dose from non-noble ga$es Dose Limits 'Total Body, ,annual Thyroid, annual Other Organs, annual 1-12 2smrern 75 mrem 25mrem Calculation using REMP TLD Comparison Indicating TLD station {OTD-8-(1)}, closest to on site *storage, 1n mrem/week mim,Js REMP environmental control {OTD-L-{C)}, in mrem/week Dext = (1.40 -1.30)

Actual REMP TLD readings do not show any deviation from historical averages for this location, both pre and post construction of the SG storage mausoleum and ISFSI. On-site TLD's used for dose monitoring at onsite rad storage facilities do not have identical counterparts at the site boundary or actual offsite receptors. Additionally the liquid dose pathway, since it is downstream of the indicator location and is not hydro-geologically connected, would produce very conservative results compared to calculating ~ctual dose. 1-13 6.8 Groundwater Monitoring Program and Observations

OPPD. conducted groundwater sampling from 19. wells, 2 surface water sites, and 4 storm water h-eaders within the site property per NEI 07-07. Additionally Nebraska requirements regarding avoidance of snow runoff were deleted, so storm water sampling is now performed qu_arterly, if available.
No new monitoring wells were added to the sampling program during 2017. Additional rc1diological surveys were perfermedduring decommissioning characterization, no plant related nuclides were discovered in son, Ttle sallipling program consist$ of2 affected sectors per rain event, anct an upwind backgrounq test. Three rain sampling events were conducted.

No tritium activity in excess of the vertdor-'s Minimum Detectable Activity (MDA) Was reported. Fourth quarter had no rain or snow events significant enough fo coiled :storm water or rain samples. No tritium activity in *excess of the vendor's Minimum Detectable Activity (MDA) was reported in collected, storm water .or rain sampling.

One monitoring wen (MW-3A). had tritium in excess of the vendor's Minimum Oetectable:ActMty (MDA < 2*95 pCi/L) was reported in Table 111:9 at326, pCi/L'+/-205 pCi/L. MW--3A detection was below any reporting th.resholds.

This well is sampled quarterly* for the entire HTD suite of analyses. No oth_er analyses hPd detected activity. No other detections were presefit in this Well *on follow up* sc1mpli_ng. MW-6 had tritium identified with activity > 2 sigma but <MDA :(281 pCi/1-) .at 195 pCVL +/-192. This result was included based on *detections near MDA from station trends for this location. This well is hydrogeology connected to the Missouri River downstream of the plant discharge and is influenced by high river levels and station discharge. All listed :sr-90 results identified < MDA; but wer~ retained during statistical data review based on historical stati.on shallow well .trends. Some hard to detect nuciides, were reduced to an annual sample frequency ( Ni-63, Fe-55, Sr;,90 in deep wells) based on 2* years. of quc1rterly sa)Jiplir1g With no detections above MDA. 1-14 i-* The Fort Calhoun REMP sampling did not detect tritium in samples within the Missouri River downstream at the site boundary or at the nearest municipal drinking water facility. No groundwater drinking pathway exists on site. Groundwater monitoring of neighboring drinking wells is performed to have data, if a plume were identified on site. No state or federal drinking water limits, and no site groundwater protection program administrative limits were exceeded. 1-15 Sl;CTIQNJI

These calculations are performed to ensure the annual dose .limits delineated in Appendix I of 10 CFR 50 and implemented by RETS are not exceeded, If the result$ of the q1Jarterly*calcµlations.exceed fifty percent (50%) of the annual limits of Appendix I, actions are taken to reduce efflue11ts so that the resµltant doses do not exceed the annual limits during the remainder oftht;) year and a s*pecial report is submitteq to the Nuclear Regulatory Commission. No special reports were required for 2017 calculated doses. This. secticm presents the results of the quarterly dose calculations performed during the period January 1, 2011through Decem~r 31, 2017. Details are shown as to the types, sources and resultant doses from the effluents, the annual limits and a comparison to the annual limits. FOR'!'

The gross gaseous activity release rates were 1.46E-05 µCi/sec for the fi{st quarter, 9. 72E-06 µCi/sec for the second quarter, O.OOE+OO µCi/sec for the third quarter, and O.OOE+OO µCi/sec for the fourth quarter. No radioactive halogens releases were released (:luring the reporting period from gaseous effluent discharges. No radioactive particulates with half-iives greater that eight days were released during the reporting period from gaseous effluent discharges. Radioactive tritium released during the reporting period totaled 3.93E-01 curies. Carbon-14 released for the reporting period totaled 0.00 curies, this is a calculated value based on reactor power and days of operation. The Fort Calhoun estimate of 0.00 curies Carbon-14 with a normalized C-14 production rate and 15% carbon dioxide fraction. Qff..:site vendor analysis of weekly composite samples indicated that no gross alpha radioactivity was released during the reporting period, IV-2 POTENTIAL DOSES TO INDIVIDUALS AND POPULATIONS A Potential Annual Doses to Individuals from Gaseous Releases To.tat body; skin, and organ doses from .ground releases were catculated in mRem to an average adult, teenager, child, and infant using the annual configuration of the GASPAR ll program. Results to. each receptor are sh.own in Taoles IV-A-1 through IV-A-40. Also, the doses to the same groups, Table IV-B:..1, in units of mRad, d.ue to gamma and beta radiation carried by air, was computed using GASPAR IL In its annual Gbnfiguration, GASPAR ll 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, 2017 through December 31, 2017 were as follows: (1) (2) (3) (4) (5) (6) All gaseous effluents Entrained gases (Ar-41, Xe;.131 M, Xe-133M, Xe-133, .Xe-135M, Xe-135, Kr:..85M, Kr-87, and Kr-88,) from liquid effluents. Annual XJQ at the actual receptor locations., which are corrected for open terrain and plume depletion, ate. calculated according to Regulatory Guide 1.111. Also included are annual deposition rates corrected for the 0pen terrain factor. The production, intake and *grazing fractions were .as follows: 1.0 for leafy *vegetaJ:>!es grown in gard(:m of interest, 0.7'3 for prodtJce gr:own in garden of interest, O.S for the pasture grazing season of the miik animal, 1.0 for pasture grazing sea~on of'the rneatanirnal, c1nd a g/m 3*for the air water '(humic;Hty) conyentrations. All dose factors, transport times frorn rec~ptor to individual, and usage factors are defined by Regulatory Guide 1.109 and NUREG-0172. Site specific information, within a five-mile radius of the plant, en types of recept()rs: located in each sec.tor was used. That is, ifa cow was not present in a sector, then the 111ilk pathway for that sector was not c;;onsider:ed; If it was present, thentl;le actual sector distance was .used. (7) Using approved methodologies the C-14 doses to the site specific pathways (e.g. inhalation, milk, meat, and vegetation pathways) age group and organs are based upon airborne composition rather than ground deposition. For this reason, X/Q is utilized to calculate doses from Carbon-14 effluent releases These inputs introduce a most conservative approach for the following reasons: ( 1) The open terrain and deposition corrections increase annual X/Q by a 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. 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 rs the summation of the dose received by all individuals and has units of man-thyroid-rem when applied to the summation of thyroid doses., The same inputs were used as in the individual case with the addition of the following: (1) A total populat.ion of 950,006 (based on the 2010 census) was used to define the sector segments within a 50-mile radius of the plant. (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 IL IV-4 T.ABLE IV-A-1 FORT CALHOUN ANNUAL 2017, DOSE PROJECTIONS SPECIAL LOCATION NO.. 1 RES AT 4.36 MILES N ANNU:AL BETA AIR DOSE= 1.39E-09 MILLRADS ANNUAL GAMMA AIR DOSE= 1.23E-11 MILLRADS PATHWAY T.BODY GI-TRACT BONE LIVER KIDNEY THYROID LUNG SKIN ---------+----------+----------+----------+----------+----------+----------+----------+----------+ PLUME : 8.04E-12 : 8.04E-12 : 8.04E-12 : 8.04E-12 : 8.04E-12 : 8.04E-12 : 2,14E-11 : 9.66E-10 : ---------+----------+----------+----------+----------+----------+----------+----------+----------+ GROUND : O.DOE+OD : O.OOE+OO : O.OOE+OO : O.OOE+OO: O.OOE+OO : O.OOE+OO : O.OOE+OO : O.OOE+OO : ---------+----------+----------+----------+---

This represents 1.88E+01 percent of the limits specified in Appendix B to 1 O CFR 20 (1.0E-06 µCi/ml for unrestricted areas), 2.2 curies of tritium were discharged at an average diluted concentration of 1,856-04 µCi/ml or 1.85E+01 percent of ECL (1.0E-03 µCi/ml). No gross alpha radioactivity was identified by Off-site vendor analysis of quarterly liquid _ composites for the reporting period. Ni-63 was identified in the third quarterly composite, and Fe-55 was identified in the second *quarterly composite.

These Hard to detect nuclides represented 4.1 % of the total activity released. Dilution water during the period amounted to 3.60E+08 liters, while liquid waste discharges consisted of 6.01 E+05 liters of radioactive liquid waste. V-2 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 LADT AP 11 program. Tne inputs to LADTAP II for the annual period from January 1, 2017 through December 31, 2017 were as follows: (1) All liquid effluents were a$ 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 dilution stream flow during periods of release was 16.04 cubic feet per second (CFS) was utilized for 2017. The average discharge rate during release.s was 16.08 cubic feet per se.cond (CFS). (3) Dilution factors (inverse of the mixing i;atios) were computed based on Regulatory C3uide 1.113 ( equation 7 in Sectipn 2.a.1 of Appendix A) for a one dimensional transport model. (4) Drinking water transport times of 6.6 hours to the Omaha intake and 7.0 hours to the Council Bluffs intake were used for dose calculations. (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 pres_ent 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, l I _ _J B. Potential Annual Doses to Population from Liquid Releases The LADTAP II program in its annual configuration was also used to calculate to total body and organ doses for the population of 950,006 within a 50-mile radius of the plant (based on the 2010 census). The same input was used as in the individual cases with the addition of the following: (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. (2) The total fish harvest for both sport and commercial purposes was calculated using an average commercial fish catch for Nebraska. V-4

January 1, 2017 -December 3,1 ! 2017 Vll-1 FCS Radiation Protection Information Use RP-5101 Revision o Page 1 of 11 PROCESS CONTROL P'ROGRAM FOR RADIOACTIVE WASTES 1.0 PURPOSE AND SCOPE 1. 1 The purpose of the .Process Control Program (PCP) is to: 1.1.1 Establish the proce.ss and boundary conditions for the preparation of specific procedures for processing, sam*pling, analysis, packaging, storage, and shipment C)f solid radwaste in accordance With local, state, and federal requirements.

1.1.2 Establish parameters which will provide reasonable assurance thatall Low Level Radioactive Wastes (LLRW), processed by the in-plant waste process systems on-site OR by on-site vendor supplied waste processing systems 1 meet the acceptance criteria to a Licensed Burial Facility; as required by 1 OCFR Part 20, 1 OCFR Part 61, 1 OCFR Part 71, 49CFR Parts 171-172, "Technical Position on Waste Form (Revision 1)" [1/91), "Low~Level Waste Lfcensing Branch Technical Position on Radioactive Waste Classification" [5/a3J, and the Station Technical Specifications~

as* applicable. 1.1.3 Provide reasonable assurance that waste placed in "on-site storage" meets the requirements as addressed within the Safety AnaJysis Reports for the low level radwaste storage facilities for dry and/orprocessed wet waste. 2.0 DEFINITIONS 2.1 Blending: The mixing of LLRW with different concentrations of radionucUdes, typically in an effort to create a relatively homogeneous mixture for disposal. 2.2 Classification _Controlling Nuclides; One or more nµciides, listed in Table 1 or Table 2 of 10CFR61:55, whose concentration is the specific basisforthe classification of the Wc!lste container. This could be a single nuclide or mlJltiple nu elides th~t make up >50% of the sum of the fractic;ms. 2.;3 Compaction: When, dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor. 2.4 Conce-ntration Averaging: The averaging of'the radionuclide concentrations for specific wastes or mixture of waste over the volume or weight of the. waste. 2.5 Dewatering: The process of removing fluids from liquid waste streams to produce a waste form that meets the requirements of 10CFR Part 61 and applicable burial site criteria, ~0.5% by volume when the waste is packaged to .an llunstable" state; or ~1 % by volume when the waste is packaged to a "stable" form. 2.6 Encapsulation: Encapsulation is the surrounding of~ radioactive soi,.irce or component with a nonradioactive material. Encapsulation involves a radioactive core surrounded by a non-radioactive matrix. Process Control Program for Radioactive Waste RP-5101 Revision 0 Page 2 of 11 Information Use 2.7 High Integrity Container (HIC}: A disposable container that is approved to the Requirements of 1 OCFR61. The use of HIC's is an alternative to solidification or encapsulation in a steel container to meet burial stability. HIC's are used to package dewatered liquid wastes, (e.g. filter cartridges, filter media, resin, sludges, etc), or dry active waste. 2.8 Homogeneous Waste: Waste in which concentrations of radionuclides of concern are likely to approach uniformity in the context of reasonable foreseeable intruder scenarios (This is because hot spots are a concern with resp.act to protection of an individual who may inadvertently intrude into the burial site). 2.9 Incineration, RVR, and/or Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where the volume is reduced by thermal means meets 1 OCFR61 requirements. 2.10 Liquid Waste Processing Systems: In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, compression dewatering, solidification, or reverse osmosis (RO) for*the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs). 2.11 Mixable Waste: Waste that is amenable to physical mixing to create relatively uniform radionuclide concentrations. 2.12 Nuclides of Concern: A nuclide in the waste in concentrations greater than 1% of the concentration of that nuclide listed in Table 1 of 1 OCFR61.55 or 1 % of the applicable class-dependent concentration of that nuclide in Table 2 of 1 OCFR61.55, Column 2 or 3. 2.13 Process Control Program (PCP): The program which contains the current formulas, sampling, analysis, tests, and detenninations to be made to ensure tha,t.processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes Will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in 10CFR Parts 20, 61 and 71, state regulations, and burial site requirements. 2.14 Solidification: Liquid .waste processed to either an unstable. or stable form per 1 OCFR61 requirements. Waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas, samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability criteria (e.g. High Integrity Container). Process Control Program for Radioactive Waste RP-5101 Revision 0 Page 3 of 11 Information Use 2.15 Solidification Media: An approved media (e.g. Barnwell -vinyl ester styrene, cement, bitumen) when waste containing riuclides with greater than 5-year half-lives is solidified in a container with activity greater than 1 micro curie/cc. Waste solidified in a HIC is approved by the commission meeting the 1 OCFR61 stabilization criteria, including 1 % free standing liquids by volume when the waste is packaged to a "stable" form and 0.5% when waste is packaged to an "unstable" form. The formulas, sampling, an*alysis, and test do not require NRC approval, because the HIC meets the stability criteria. 2.15.1 Solidification to ah unstc1ble or $table state is performed by vendors, when applicable. Liquid waste solidified to meet stabilization criteria (1 OCFR61 and 01-91 Branch Technical Requirements) shall have documentation available that demonstrates that the process is approved by the NRC or disposal facility. 2.16 Stabilization: Liq1,Jid waste processed to a "stable state" per 1 OCFR61 Requirements. Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification "stabilization" criteria. This processing method is currently not available., because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples, tests, etc. 2.17 Waste Streams: Co_nsist of but are not limited to 2.17.1 Filter media (powdered, bead resin and fiber), 2.17.2 Filter cartridges, .2.17.3 Contaminated charcoal, 2.17.4 Fuel pool activated hardware, 2.17 .5 Oil Dry absorbent material added to a container to abs.orb liquids 2.17.6 Sump and tank sludges, *2.17. 7 High activity filter cartridges, 2.17.8 Con~ntrated liquids, 2.17.9 Contaminated waste oil, 2.17 .10 Dri.ed sewage or wastewater plant waste, 2, 17.11 Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities; 2.17 .12 Other radioactive waste generated from cleanup of inadvertent contamination. 3.0 RESPONSIBILITIES 3.1 Implementation of this Process Control Program (PCP) is described in procedures and is the responsibility of th.e Radiation Protection and Chemistry Departments to implement.

Specific requirements associated with the disposal shall be incorporated into station implementing procedures. Process Control Program for Radioactive Waste RP-5101 Revision 0 Page 7 of 11 lnfonnation Use 6.2.12 Concentration averag1ng may be PERFORMED to combine LLRW having different concentrations of radionuclides to form a homogeneous mixture in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation-1995, NRC-2011-0022: A. For homogeneous waste types such as resins and filter media, the concentration of the mixture for classification purposes may be based on either the highest radionuclide concentration in any of the individual waste types contributing to the mixture or the volumetric or weight-averaged nuclide concentrations in the mixture provided that the concentrations of the individual waste type contributors to the mixture are within a factor of 10 of the average concentration of the resulting mixture. (A designed collection of homogeneous waste types (from different sources within a facility) is not considered 'mixing' and the concentration for classification purposes may be the average concentration of the combination).

8. For non-homogeneous waste types such as activated metals, cartridge filters or components incorporating radioactivity in their design, the concentration should be determined from the total weight or displaced volume (excluding major void spaces) of the component.

Mixtures of components in a disposal container is permissible. Concentration averaging of a mixture of components of similar types can be performed in accordance with the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and any State or Disposal Site specific requirements. 6.2.13 Blending may be PERFORMED for routine LLRW such as resins and filter media in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation as further clarified in SECY 2010-0043. The concentration of the mixture may be determined based on the total activity of all components in the mixture divided by the total volume or mass of the mixture. Reasonable effort should be made to mix blended LLRW so that activity Is evenly distributed. 6.2.14 Encapsulation may be PERFORMED for routine wastes such as filters, filter cartridges, or sealed sources centered in an encapsulated mass, in accordance with the guidance in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation. Classification may be based on the overall volume of the final solidified mass provided that; A. The minimum solidified volume or mass should be reasonably difficult to move by hand. 8. The maximum solidified volume or mass used for determining concentration for any single discrete source, should be no more than 0.2 m 3 or 500Kg (typically 55-gallon drum). C. The maximum amount of gamma-emitting radioactivity or radioactive material is <0.02 mrem/hr on the surface of the encapsulatior:t over a 500-year decay period. ' Process Control Program for Radioactive Waste RP-5101 Revision O Page-8 of 11 Information Use D. The maximum amount of any radionuclide in a single encapsulation, when averaged over the waste and encapsulating media, does not exceed the maximum concentration limits for Class C waste. E. Written procedures should be established to ensure that the radiation source(s) is reasonably centered (or distributed) within the encapsulating media. F. All other disposal facility requirements for encapsulated material are met. 6.3 Burial Site Requirements 6.3.1 Waste sent directly to burial shall COMPLY with the applicable parts of 49CFR171-172, 10CFR61, 10CFR71, and the acceptance criteria for the applicable burial site. 6.4 Shipping and Inspection Requirements 6.4.1 All shipping/storage containers shall be INSPECTED, as required t>y stcltion procedures, for compliance with applicable requirements (Department of Transportation (DOT), Nuclear Regulatory Commission (NRC), station, on-site storage, and/or burial site requirements) prior to use. 6.4.2 Containers of solidified liquid waste shall be INSPECTED for solidification quality and/or dewatering requirements per the burial _site, offsite vendor acceptance, or station acceptance criteria, as applicable. 6.4.3 Shipments sent to an off-site processor shall be INSPECTED to ensure that the applicable processor's waste acceptance criteria are being met. 6.4,4 Shipments sent for off-site storage shall MEET the storage site's waste acceptance criteria. 6.5 Inspection and Corrective Action 6.5.1 Inspection results that indi_cate non-compliance with applicable NRC, State, vendor, or site requirements shall be IDENTIFIED and TRACKED through the Corrective Action Program. 6.5.2 Administrative controls for preventing unsatisfactory waste forms from being released for shipment are described in applicable station procedures. If the provisions of the Process Control Program are not satisfied, then SUSPEND shipments of defectively packaged radioactive waste from the site. 6.5.3 If freestanding water or solidification not meeting program requirements is observed, then samples of the particular serie.s of batches shall be TAKEN to detennine the cause.

The REMP is a requirement of the. Fort Calhoun Station (FC~) operating license. It was initiated prior to plant operation in 1973. The main purpose of the REMP is to ensure public safety by monitoring plant discharges and assessing the effect, if any, of plant operations on the environment.

Samples are collected that would account for various exposure pathways such as ingestion, inhalation, adsorption and direct exposure. Samples collected on a regular basis include: air, surface water; ground water, milk, vegetation, fish, sediment, and food crops. Direct radiation is measured by thermoluminescent dosimeters (TLDs ). These samples and TLDs are sent to an independent vendor laboratory for analysis. The vendor uses analytical methods that are sensitive. enough to detect a .level of activity far below that which would be considered harmful. Locations for sample collection are based on radiological. and meteorological data from the Annual Effluent Release Report and information obtained from the Environmental Land Use Survey. Most samples, particularly indicator samples, are collected in a circular area within a five-mile radius of plant containment. (However, control locations are usually outside of five miles.) This circle is divided into sixteen equal sectors, each assigned an identification letter "A" through "R" (note: letters "I" and "O" are not used, as they may be mistaken for the numbers "1" and "O"). Sector "A" is centered on Nor:th or zero degrees. Sectors are also given directional labels such as "West-Southwest" ("WSW"). Sample locations are listed by number atong with their respective distances and direction from plant containment, in the Offsit~ Dose Calculation Manual (ODOM). When assessing sample results, data from indicator locations (those most likely to be affected by plant operations) are compared to those from control locations (those least or not likely to be affected). Results from an indicator location which were significantly higher than those from a control location could indicate a attributable effect and could require additional investigation. The .results of the sample analyses, as required by the FCS Offsite Dose Calculation Manual (ODCM), are presented in the attached stc1tistical tables in accordance with Table 1 of Regulatory Guide4.8, "Environmental Technical Specifications for Nuclear Power Plants." Sample collection was conducted by plant chemistry/environmental staff. A contract vendor .(Environmental Inc,, Northbrook, .Illinois) performed sample analyses, preparation of monthly reports and the statistical evaluation of sample results. All vendor analysis techniques met the sensitivity requirements as stated in the ODCM. Results for 2017 were within expected ranges and compared closely with historical results. The result details and exceptions are listed in the following sections. Page 2 of 13.

1) Ambient Gamma Radiation Ambient gamma radiation is measured by thermoluminescent dosimeters (TLDs) provided by the vendor laboratory.

These dosimeters contain calcium sulfate phosphors and are processed quarterly. One incident condition report was documented in the Corrective Action Program in 2017 related to TLD sampling. Multiple TLD locations could not be accessed safely due to structural concerns with the site met tower. Repairs to the tower could not be made due to the presence of an active raptor nest on the tower. Once the nesting season had ended, the TLD's in question were obtained and counted. The reading period was extended and quality data was returned for the two quarters the TLD's were in the field. The samples were added to Table 3.0 to help reviewers of this report since the vendor attachments show that not all TLD's were collected/read. TLD OTD-1C was not recovered due to a local county road worker replacing the road sign/pole. (Condition Report 2017-01839). This sample was added to Table 3.0 All sample results are within the range of historical data and displayed less than 17% difference when compared to historical averages. All results were less than 3 sigma standard deviations from historical means. No discrepancy between released effluents and resultant radiation dose measured was observed. No changes in plant operation/procedures are required based upon observed impacts to the environment to date. Twelve TLD's were added to the station's ODCM. These TLD's were placed within the owner controlled area to assist with determination of 40 CFR 190 doses. These locations are not included in Table 1.0, but are being described to assist reviewers of vendor analysis records. 10-Year Trend Comparison of TLD Locations Location Avg. Dose (mr/week) 2017 Avg.

2) Milk/Pasture Milk samples or pasture grasses, if milk is temporarily unavailable, are collected every two weeks during the pasture season from the beginning of May through September, and monthlylhe test ofthe calendar year. Indicator samples are collected from a herd of milk, goats at a family farm located approximately 3-4 miles from the plant in Sector J (SQuth). The control samples are collected Jrom a commercial dairy cow herd located approximately 9.9 miles from the plant in Sector J (South). The indicator station and control location are unchanged from last year. No indicator milk samples were available until spring (May) due to the dairy owners suspending operations.

Late fall samples were nqt performed due to the does drying up before birthing. Pasture grass in lieu of milk was collected at the indicator location due to unavailability. All sample results for Cesium-134, Cesium-137 and other gammas were at the LLD for both indicatpr and control locations. No plant-related effects were observed.

3) Fish Fish are collected on an annual basis. Control samples are collected at a location approximately twenty miles upstream of the plant (river miles 665 -667). Indicator samples are collected in the immediate vicinity of the power plant (river miles 644 -646). Several species of fish, important to commercial and recreational interest, representing all levels of the aquatic food chain are collected at both locations.

All sample results are within the range of historical data. Results from both control and indicator locations were less than LLD for all gamma emitters, indicating no plant-related effects., 4) Food Crop Based on the results of the biennial Land Use Survey, the hearest high deposition pathway for food crops is the Alvin Pechnik Farm in Sector H {0.94111iles, 163°). Accorciingly, v~getable samples were coll_ected at Alvin Pechnik Farm for the purposes of the 2017 REMP. Samples were com.Parable. with historical results arid within the range of results reported from the control location garden at Mohr Dairy. Additional

special interest samples were obtained from on-site farm fields per plant TechnicaJ Specifications.

All results were at the LLD for all n*on-naturally occurring radionuclides. No plant-related effects were observed.

5) Sediment River s_ediment samples are collected twice *a year at an upstream control location and a downstream indicator location.

All results were at the LLD for all non-naturally occurring radionuclides. No related effects were observed. Page 4 of 13

6) 7) 8) Air Monitoring Air sample results for 2017 were well within historical limits for all locations.

Additionally, all indicator locations showed results very similar to the control locations. One incident was documented in the Corrective Action Program in 2017 related to air sampling. CR 2017-01904 Air Iodine (Al) sample did not meet the LLD due to less than adequate air sample volume after a sample pump failure .. Since identjfil3d activity was identified on the pre-filter the Gross Beta sample was not impacted. This sample is documented in Table 3.0. All sample results are within the range of historical data. All indicator locations displayed less than 15% difference when compared to historical average. All 2017 results when compared to historical averages are within the stated vendor error acceptance tolerance. Results from both control and indicator locations were less than LLD for gamma emitters and iodine. No changes in plarit operation/procedures.are required based upon observed impacts to the environment to date. 10-Ye.ar Trend Comparison of Air Sampling Locations Location Avg.

Environmental Inc. participates in inter-laboratory comparison check) programs as part of its quality control program. These programs are operated by such agencies as the Department of Energy, which supply blind-spike samples such as milk or water containing concentrations of radionuclides unknown to the testing laboratory. This type of program provides an independent check of the analytical laboratory's procedures and processes, and provides indication of possible weaknesses. In addition, Environmental Inc. has its own in-house QA program of blind-spike and duplicate analyses. Vendor in-house spike sampling was performed without a failure and in-house blank analyses were performed within acceptable ranges. Routine FCS REMP duplicates samples were performed by the vendor to verify reproducibility of results. All duplicates were within acceptance criteria. Three DOE MAPEP cross check samples failed in 2017. DOE water sample MAW-847 dated 2/1/2017, failed for Co-57. The laboratory report had a decimal point misplaced during unit conversion. The result was within control limits when the proper unit conversion was performed. Third quarter MAW testing for C0-57 was performed within acceptable limits. DOE air particulate sample, MAAP 907 failed high on its Am-241 results due to plating issues. Sample was reanalyzed in duplicate with acceptable results. The MAAP sample failed low during 3n1 quarter Am-241 testing, however the DOE is no longer offering Am-241 testing for air particulates, so this failure was not addressed. Testing on ERA air particulate for Am-241 ERAP-1112 was successfully completed by the vendor. Am-241 is currently not performed in the REMP program but performed in house as part of the REMP program. No Am-241 was detected in effluent releases, and FCS personnel passed its Analytics cross checks for Am-241. Environmental Resource Associates cross checks had four failures during 2017. ERA air particulate sample, ERAP-1112, failed high for Fe-55 on 3/20/2017. Insufficient sample existed to re-perform the analysis, so the sample was re-counted for an extended count and successful results were obtained. ERAP-1114 failed Gross Beta analysis high outside limits. The ERA samples appear to have been deposited in a pattern closer to the center of the filter changing the efficiency calculation (low) causing the report activity to be high. In house spiked samples had a test ratio 0.94 for sample prepared by Environmental Inc, Soil sample ERS0-1116 (low) on the following isotopes Pu-29, Pu-240, U-233 and U-234. These analytes passed after re-analysis. Poor electroplating was listed as a potential cause. Water sample, ERW-11120, failed high for Fe-55. Sample was recounted and acceptable resulted were generated. Insufficient sample was left after water testing to perform the entire analysis. The FCS REMP program does not perform Fe-55 or Transuranic analyses on its samples. Gross Beta results obtained were within historical means and did not show a high bias, No test results failed both the ERA and DOE methodologies for a given sample type. Reanalysis produced acceptable results. The ordering of additional tests and successful testing after corrections were applied, visibly demonstrates the vendor's commitment to reporting and resolving deficiencies. These results indicate the vendor's ability to self-identify and correct any deviations from acceptable or expected results. The test results had no impact on Fort Calhoun samples and were documented as such by the vendor. No changes are deemed necessary to the FCS REMP program due to vendor performance. Page 13 of 13

These programs are operated by ctgencies which supply eriVironmental .type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide en Independent check on a laboratory's analytical procedures and to alert it of any possible problems, Participant.laboratories measure the concentratlQn pf specified radionuclldes and report them to the issuing agency. Several mo.nths later, the agency reports the known values to the participant laboratories and specifies controt limfts. Results consistenUy higher or lower than the k.now*ri values or outside the control limits indicate a* need to check the Instruments or procedures used. Results in TableA-1 were obtained through participation in the RAD PT Study .Proficiency Testing Program administered by Environmental Resources Associates, serving as, a replacement for studies conducted previously by the v.s.

This likeiy caused the efficency used the calculation to be understated and the reault obtained by the laboratory to be overstated.

A7-2 ---l APPENDiXB DATA REPORTING CONVENTIONS Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period. 2.0. Single Measurements Each single measurement is reported as follows: x +/- s where: x = value of the measurement; s = 2S counting uncertainty (corresponding to the 95% confidence level). In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample. 3.0. Duplicate analyses 3.1 Individual results: For two analysis results; x1 +/- s1 and x2 +/- s2 Reported result: x +/- s; where x = (1/2) (x1 + x2) ands= (1/2) 3.2. Individual results: L2 3.3. Individual results: otherwise. X +/- S, <L Reported result: <L, where L = lower of L1 and Reported result: X +/- s if X .!: L; <L 4.0. Computation of Averages and Standard Deviations B-2 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements OVE!r the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviations of a set of n numbers x1, x2 ... xn are defined as follows: s= -~ -\J~ 4.2 Values below the highest lower limit of detection are not included in the average. 4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported. 4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported. 4.5 In rounding off, the following rules are followed: 4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanger;l. As an example, 11.:443 is rounded off to 11.44. 4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45. 4.6 Composite samples which overlap the next month or year are reported for the month or year in which most of the sample is "°llected.
