DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT MAXIMUM PERMISSIBLE CONCENTRATIONS Dose rates, rather than effluent concentrations, are used to calculate permissible release rates for gaseous effluents. The maximum pem1issible dose rates for gaseous releases are defined in Duane Arnold Offsite Dose Assessment Manual (ODAM). ODAM Limiting Condition for Operation (OLCO) 6.2.2. Liquid effluent concentrations are limited per ODAM OLCO 6.1.2 to ten times (lOx) the concentration specified in 10CFR20 Appendix B, Table 2, Column 2. A VERAGE ENERGY The ODAM limits dose rates at or beyond the site boundary due to the release of noble gases to less than or equal to 500 mrem per year to the total body and less than or equal to 3,000 mrem per year to the skin, and average energy is not used to determine dose to the public. Compliance with these limits is demonstrated based on dose calculations using measured isotopic concentrations of effluent streams and not based on gross count rate measuring systems.

Therefore, the average beta and gamma energies (E-BAR) for gaseous effluents as described in Regulatory Guide 1.21 "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," are not applicable.

MEASUREMENTS OF TOTAL RADIOACTIVITY Gaseous Effluents

Gaseous Effluents from the Offgas Stack, Reactor Building Vents, Turbine Building Vent and the Low Level Radwaste Storage and Processing Facility (LLRPSF) are continuously sampled for iodines and particulates. Sample media is changed weekly and analyzed by gamma spectroscopy. The gross alpha analyses are performed onsite. The particulate filters are composited on a quarterly basis and sent to a vendor for Sr-89, Sr-90, Fe-55 and Ni-63. Total error is calculated based on stack flow error, sample flow error, and analytical error.
Noble gas grab samples of the same four release points are obtained monthly and analyzed by gan11Tia spectroscopy. Total error is based on stack flow error, analytical error, and calculated sampling error.
Tritium samples from all four release points are obtained quarterly and analyzed by liquid scintillation. Total error is based on stack flow error, analytical error, and calculated sampling error.
A beta sensitive radiation detector provides for continuous monitoring at each of the above described release points. For the year 2016, there were no instances where ODAM required gaseous radiation monitoring or sampling systems were inoperable on an active release point for a period of 30 (contiguous) days or more. (ODAM OLCO 6.2.1.1 A.2)

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT Liquid Effluents

Service water systems are sampled once per week for gamma emitters. Portions of the weekly service water samples are composited for a monthly analysis for tritium and gross alpha. If there is a positive identification ofreactor by-product radioactivity in these samples, analysis for Sr-89, Sr-90 and Fe-55 are performed. Total error is based on the volume discharge error and analytical error.
ODAM defined "Clean" Systems are sampled prior to free release. Samples are collected prior to release and analyzed for gamma emitters and tritium. If reactor byproduct gamma emitters are identified, analyses for Si-89, Sr-90 and Fe-55 are performed. "Clean Systems" include: CST Containment Pit, Transformer Pit, Neutralizing Tank 1T022, and FRAC tanks. Total error is based on the volume discharge error, dilution flow error and analytical error.
No radioactive batch releases ofliquids from plant radwaste systems were perfom1ed in 2016. There were 97 radioactive batch releases of tritiated groundwater and rainfall recapture from catch basins.

All releases were less than 6,000 pCi/L. The DAEC Groundwater Protection Plan Administrative Control Procedure, ACP 1411.35, tritium limit is 20,000 pCi/L, which is identical to the EPA drinking water limit for tritium.

Continuous monitoring with gamma sensitive radiation detectors is provided for plant service water systems. For the year 2016, there were no instances where these liquid radiation monitoring systems were inoperable on an active release point for a period of 30 (contiguous) days or more. (ODAM OLCO 6.1.1.1 A.2)

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT GASEOUS EFFLUENTS There were no radioactive gaseous batch releases from the Duane Arnold Energy Center during this report period. All gaseous effluent releases were continuous and resulted in a small fraction of the 10 CFR 50, Appendix I dose objectives. For all release points, quarterly average gross alpha concentration of radioactivity measured less than 4.IOE-09 µCi/cc. There were no Abnormal releases of gaseous effluents during the period.

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT Estimated Release of Gaseous ofCarbon-14 The estimate of gaseous carbon-14 (C-14) released from the Duane Arnold Energy Center was derived using the EPRI document, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents", Report

1021106, issued December 2010. The site specific source term for the DAEC was estimated using the proxy generation rate values from Table 3-1 and the actual 2016 power history for the site.

The total amount of C-14 released from the site in 2016 was estimated to be 8.64 Curies. Using the dose calculation methodology from Regulatory Guide 1.109, the resultant maximally exposed receptor organ from C-14 is the bone of a child, located 2,470 meters towards the East-Northeast. The dose is 1.13E-01 mRem (0.113 mrem). This is a fraction of the l 1mem annual whole body dose received to the average US citizen from natural occurring carbon-14, primarily generated through cosmogenesis in the terrestrial biosphere. (

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT RADIOLOGICAL IMPACT ON MAN The annual offsite radiation dose to a member of the public was determined by assessment of environmental dosimetry results, by calculations based on monitored effluent releases and by estimating the release of gaseous carbon-14. Dose Contribution from Direct Radiation Direct radiation dose from the operation of the DAEC was reported by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM). Pre-operational and 2016 TLD results were evaluated with a paired difference statistical test. The evaluation concluded that there were no significant differences in the TLD populations for the 0.5 mile, 1 mile and control TLD populations. Estimated Offsite Dose from Effluent Releases The contribution of dose to a member of the public most likely to be exposed from liquid and gaseous effluent releases was calculated using the Meteorological Information and Dose Assessment System (MIDAS) computer program in accordance with the ODAM. The calculation methods follow those prescribed by 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". Dose to members of the public from carbon-14 in gaseous effluent is calculated separately and is described below. Results of the MIDAS dose calculations are displayed here: 1.) There were 97 batch releases of radioactive material to liquid effluents (groundwater mitigation) in 2016. 2.) The maximum dose to air at the site boundary from noble gases released was 0.00162 mrad from gamma radiation at 936 meters towards the Northwest. 3.) The maximum dose to air at the site boundary from noble gases released was 0.00213 mrad beta radiation at 1176 meters towards the North. 4.) The whole body dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.0032 mrem, at 2120 meters towards the Northwest. 5.) The skin dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.0038 mrem, at 2120 meters towards the North. 6.) The hypothetical maximally exposed organ due to airborne iodines and particulates with half-lives greater than eight days (excluding carbon-14) was the lungs of a child at 805 meters towards the West, with an estimated dose equivalent of0.00617 mrem. 7.) The hypothetical maximally exposed organ due to airborne carbon-14 was the bone of a child located 2470 meters to the North of the site. The dose was 0.113 mrem. Page 20

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT Conclusion No measurable dose due to the operation of the DAEC was detected by environmental TLDs in 2016. The calculated doses are below the regulatory limits stated in Appendix I to 10CFR50 and in 40CFR190.

DUANE ARNOLD ENERGY CENTER 2016 ANNUAL RADIOACTIVE MATERIAL RELEASE REPORT

SUMMARY

OF GROUNDWATER PROTECTION INITIATIVE ISSUES The Duane Arnold Energy Center has committed to the Nuclear Energy Institute's Industry Groundwater Protection Initiative - NEI 07-07. Per NEI 07-07, the following information is presented:

Ground Water Protection Program (GWPP) samples were collected and analyzed in accordance with the requirements and guidance of the site procedure ACP 1411.35.

Program results are presented in Attachment 1.

No reactor-by-product gamma emitting isotopes were identified.
In February 2016, the GWPP routine sampling identified a contaminate plume in the shallow aquifer (less than 25 feet deep). Release standards are set forth in Section 6.0, Radiological Liquid Effluent Release 0.6.1.2, Table 7.1-2. In accordance with GWPP Administrative Control Procedure (ACP) 1411.35 and Environmental Protection Agency (EPA) drinking water standards for tritium, 20,000 pCi/L, groundwater batch and continuous releases are expected less than (<) 20,000 pCi/L.
Tritium concentrations range from non-detectable at less than 180 pCi/L to 296,589 pCi/L from monitoring well MW-22A (D-66). No site or neighboring drinking water wells are installed in this shallow aquifer and no tritium has been identified in neighboring drinking water wells or onsite drinking water (deep aquifers). The EPA Drinking Water Standard for tritium is 20,000 pCi/L and equates to an annual dose of 4 mrem/yr. Using extraction well EW-OlA (D-68) discharge water with an average concentration of 3,070 pCi/L and assuming EW-OlA is the only drinking water source for an entire year, the maximum dose consequence would be approximately 0.614 mrem/yr.

The highest concentration from EW-OlA was 5,860 pCi/L and equates to approximately 1.172 mrem/yr.

In 2016, there was one instance where state and local officials were notified of a spill of radioactive liquid.

COURTESY OFFSITE NOTIFICATION MADE TO STATE AND COUNTY OFFICIALS "On April 12, at 1235 CDT, Duane Amold Energy Center contacted officials with the State oflowa (Bureau of Radiological Health and Department of Natural Resources) and Linn County Public Health Department in accordance with the nuclear industry voluntary reporting criteria contained in NEI 07-07

      'Industry Ground Water Protection Initiative'. The site contacted the agencies as courtesy to notify them about the identification of low levels of tritium found within the site's protected area from a potential new source. Samples were taken, and no regulatory limits were exceeded. The site team is working with industry experts on pinpointing the cause and installing an extraction well to remediate the situation.
      "This report is being made in accordance with 10 CFR 50.72(b)(2)(xi), as a result of notification to offsite agencies.
      "The Licensee has notified the NRC Resident Inspectors.
      "There is no risk to plant employees, the public or drinking water."

See Attachment IA and lB for analyses results from samples collected for the GWPP.
