I. PREFACE The following sections of the preface are meant to help define key concepts, provide clarity, and give context for the readers of this report .
A. Annual Reports The Nuclear Regulatory Commission (NRC) is the federal agency which has the role of protecting the health and safety of the public as it relates to nuclear energy. Nuclear Power Plants provide two reports annually to the NRC; these reports address how the station's operation impacts the environment of the local community. The NRC then reviews these reports and makes them ava il able to the public . The names of the reports are the Annual Radioactive Effluent Release Report (ARERR) and the Annual Radiological Environmental Operating Report (AREOR).
The AR ERR reports the results of a station' s effluent monitoring program . An effluent is a liquid or gaseous waste containing plant-related radioactive material emitted at the boundary of the facility.
The AREOR reports the results of samples obtained in the environment surrounding the station; these sample are analyzed for radioactivity. Environmental samples include air, water, vegetation, and other sample types that are identified as potential pathways through which radioactivity can reach humans .
Graph ic 1. Examples of Gaseous and Liquid Effluent Pathways Graphic 1 demonstrates some potential exposure pathways from Calvert Cliffs Nuclear Power Plant. The ARERR and AREOR together ensure Nuclear Power Plants are operating in a manner that is within established regulatory commitments meant to adequately protect the public.

CAL VERT CLIFFS NUCLEAR POWER PLANT AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOACTIVE EFFLUENT RELEASE ANNUAL REPORT - 2018 B. Understanding Rad iation Generally radiation is defined as emitted energy in the form of waves or particles. If radiation has enough energy to displace electrons from an atom it is termed " ionizing" , otherwise it is " non-ionizing" . Non-Ionizing radiation includes light, heat given off from a stove, radiowaves and microwaves . Ionizing radiation occurs in atoms, particles too small for the eye to see . So, what are atoms and how does radiation come from them?

Builclnga
~ &~ AIOmie Grains Protozoans BacfBria Molecules Atoms of suga r nu clei An atom is the smallest part of an element that maintains the characteristics of that element. Atoms are made up of three parts : protons, neutrons, and electrons .
Graphic 3. Structure of on Atom Electron The number of protons in an atom determines the element. For example, a hydrogen atom w ill always have one proton while an oxygen atom will always have eight protons . The protons are clustered with the neutrons forming the nucleus at the center of the atom . Orbiting around the nucleus are the relatively small electrons.
Isotopes are at oms that have the same number of protons but different numbers of neutrons. Different isotopes of an element wi ll al l have the same chem ical properties and many isotopes are radioact ive wh ile other isotopes are not rad ioactive . A radioactive isotope can emit radiation because it contains excess energy in its nucleus . Radiactive atoms and isotopes are also referred to as radionuclides and radioisotopes .
There are two basic ways that rad ionuclides are produced at a nuclear power plant. The first is fission, which creates radionucides that are called fission products. Fission occurs when a very large atom, such as uranium-235 (U-235) or 3
ENCLOSURE (1)
CAL VERT CLIFFS NUCLEAR POWER PLANT AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOACTIVE EFFLUENT RELEASE ANNUAL REPORT - 2018 plutonium -239 (Pu-239), absorbs a neutron into its nucleus making the atom unstable. The unstable atom can then split into smaller atoms . When fission occurs there is a large amount of energy released in the form of heat. A nuclear power plant uses this heat to produce steam . The steam is directed toward a turbine, forcing it to spin . The spinning of the turbine is used to produce electricity.
The second way a rad ionuclide is produced at a nuclear power plant is through a process called activation. The radionuclides produced in this method are termed activation products. Pure water that is used to cool the reactor and also to produce steam to turn the turbines . Although this water is considered to be very pure, there are always some contam iniants within the water, either from material used in the plant's construction or from the operation of the plant .
These contaminants are exposed to the fission process and may become activation products . The atoms in the water itself can also become activated and create rad ionuclides .
Over time, radioactive atoms will reach a stable state and no longer be radioactive . To do this they must release their excess energy. Th is release of excess energy is called rad ioactive decay. The time it takes for a radionuclide to become stable is measured in units called half-lives. A half-life is the amount of t ime it takes for half of the original rad ioactivity to decay. Each radionuclide has a specific half-life. Some half-lives can be very long and measured in years while others may be very short and measured in seconds .

We are mostly concerned about man-made rad ionuclides because they can be produced as by-products when generating electricity at a nuclear power plant. It is important to note that there are also ot her ways man-made radionucl ides are produced, su ch as detonating nuclear weapons . Weapons t esti ng has deposited some of the same man-made rad ionuclides into the environment as those generated by nuclear power, and some are still present today because of long half-lives.

CALVERT CLIFFS NUCLEAR POWER PLANT AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOACTIVE EFFLUENT RELEASE ANNUAL REPORT - 2018 C. Measuring Radiation There are four different but interrelated units for measuring radioactivity, exposure, absorbed dose, and dose equivalent. Together, they are used to report amounts of radiation and quantify its effects on humans .
- Radioactivity refers to the amount of ionizing radiation released by a material. The units of measure for radioactivity used within the AREOR and ARERR are the curie (Ci) . Small fractions of the Ci often have a prefix, such as the microcurie (µCi) , which means 1/1 ,000,000 of a Curie.
- Exposure describes the amount of radiation traveling through the air. The units of measure for exposure used within the AREOR and ARERR are the roentgen (R) . Traditionally direct radiation monitors placed around the site are measured milliroentgen (mR) , 1/1 ,000 of one R.
- Absorbed dose describes the amount of radiation absorbed by an object or person . The units of measure for absorbed dose used within the AREOR and ARERR are the rad . Noble gas air doses reported by the site are measured in millirad (mrad) , 1/1,000 of one rad.
- Dose equivalent (or effective dose) combines the amount of radiation absorbed and the health effects of that type of radiation. The units used within the AREOR and ARERR are the roentgen equivalent man (rem) . Regulations require doses to the whole body, specific organ , and direct radiation to be reported in millirem (mrem) , 1/1 ,000 of one rem .
D. Sources of Radiation People are exposed to radiation every day of the ir lives and have been since the dawn of mankind . Some of this radiation is naturally occurring while some is man-made . There are many factors that will determine the amount of radiation individuals will be exposed to such as where they live, medical treatments, etc. The average person in the United States is exposed to approximately 620 mrem each year. 310 mrem comes from natural sources and 310 from man-made sources. The Graphic 5 shows what the typical sources of rad iation are for an individual over a calendar year :

Radiation Risk Current science suggests there is some risk from any exposure to radiation. However, it is very hard to tell whether cancers or deaths can be attributed to very low doses of radiation or by something else . U.S. radiation protection standards are based on the premise that any radiation exposure carries some risk.
The following graph is an example of one study that tries to relate risk from many different factors. This graph represents risk as "Days of Lost Life Expectancy" . All the categories are averaged over the entire population except Male Smokers, Female Smokers, and individuals that are overweight. Those risks are only for people that fall into those categories. The category for Nuclear Power is a government estimate based on all radioactivity releases from nuclear power, including accidents and wastes .

III. MAXIMUM PERMISSIBLE CONCENTRATIONS A. Fission and Activation Gases Prior to the batch release of gaseous effluents, a sample of the source is collected and analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. The identified radionuclide concentrations are evaluated and an acceptable release rate is determined to ensure that the 4ose rate limits of ODCM 3 .11.2.1 are not exceeded.
B. Iodines and Particulates with Half Lives Greater than Eight Days Compliance with the dose rate limitations for iodines and particulates is demonstrated by analysis of the charcoal and particulate samples of the station main vents. The charcoal samples are analyzed by gamma spectroscopy for quantification of radioiodine. 'fhe particulate samples are analyzed by gamma spectroscopy for quantification of particulate radioactive material. Monthly composites of the main vent particulate filters are analyzed for gross alpha. Quarterly composites are analyzed for Sr-89 and Sr-90. All of the above parameters are calculated according to the methodology specified in the ODCM. Additionally, two quarterly composites are analyzed for Fe-55; the Fe-55 analysis is not required by the ODCM, but is driven by site procedure.
C. Liquid Effluents )
The Maximum Permissible Concentrations (MPCs) used for radioactive materials released in liquid effluents are in accordance with ODCM 3 .11.1.1 and the values from 10 CPR Part 20, Appendix B, Table II, Column 2 including applicable table notes. In all cases, the more restrictive (lower) MPC found for each radionuclide is used regardless of solubility.

- 1. The waste gas RMS, O-RE-2191, exceeded the 30 days inoperable time period allowed in ODCM section 3.3.3.9. The monitor was declared inoperable on 7/12/13, and has remained inoperable since that time. The RMS is scheduled to be replaced in the year 2020.
- 2. The unit 1 steam generator blowdown effluent line radiation monitors exceeded the 30 days inoperable time period allowed in ODCM section 3.3.3.10. Compensatory grab samples were performed at least once per 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> during discharges. One channel of radiation monitors was restored on January 27th, 2018 when 1RIC4014 was returned to service. 1RIC4014 went out of service on December 13th, 2017. 1RIC4095 was retroactively declared inoperable from November 22nd, 2017 through the entire calendar year due to a missed surveillance test (calibration).
- 3. The unit 2 steam generator blowdown flow rate measurement exceeded the 30 days inoperable time period allowed in ODCM section 33.3.10. Compensatory flow estimates were performed once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> during releases. The indication issue occurred on November 24th, 2018. The flow indicator 2Ff4089 required corrective maintenance that could not be completed within 30 days due to parts availability.

VI. MEASUREMENTS AND APPROXIMATIONS AND TOTAL RADIOACTIVITY A. Fission and Activation Gases
- 1. Batch Releases Prior to each batch release of gas from a pressurized waste gas decay tank or containment, a sample is collected and analyzed by gamma spectroscopy using a germanium detector for the principal gamma emitting noble gas radionuclides. The total activity released is based on the pressure/volume relationship (gas laws). The Plant Vent Stack Radiation Monitor and the Wide Range Gas Monitor typically monitor containment releases, and the values from the radiation monitor may be used to assist in the calculation of activity discharged from containment during venting. Carbon-14 is estimated using methodology from EPRI Technical Report 1021106, as described in section IV .A. l.
- 2. Continuous Releases A gas sample is collected at least weekly from the main vents and analyzed by gamma spectroscopy using a germanium detector for the principal gamma emitting noble gas radionuclides. The total activity released for the week is based on the total sample activity decay corrected to the sample time multiplied by the main vent flow for the week. The Plant Vent Stack Radiation Monitor continuously measures routine plant vent stack releases, per design, and the values from the radiation monitor may be used to assist in the calculation of activity discharged in routine plant vent stack discharges.
During each containment purge, a gas sample is collected and analyzed by gamma spectroscopy using a germanium detector to determine the concentration of principal gamma emitting noble gas radionuclides inside containment. Total activity released during a containment purge is based on continuous radiation monitor responses, grab samples, and purge fan flow rate.
A monthly composite sample is collected from the main vents and analyzed by liquid scintillation for tritium. The total tritium release for the month is based on the sample analysis and the main vent flow.

CALVERT CLIFFS NUCLEAR POWER PLANT AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOACTIVE EFFLUENT RELEASE ANNUAL REPORT - 2018 Carbon-14 is estimated using methodology from EPRI Technical Report 1021106, as described in sec ti on IV .A. l.
B. Iodine and Particulates
- 1. Batch Releases The total activities of radioiodines and particulates released from pressurized waste gas decay tanks, containment purges, and containment vents are accounted for by the continuous release methodology discussed in section Vl.B.2.
- 2. Continuous Releases During the release of gas from the main vents, samples of iodines and particulates are collected using a charcoal and particulate filter, respectively. The filters are removed weekly (or more often) and are analyzed by gamma spectroscopy using a germanium detector for significant gamma emitting radionuclides. The total activity released for the week is based on the total sample activity decay corrected to the midpoint of the sample period multiplied by the main vent flow for the week. A plate-out correction factor is applied to the results to account for the amount of iodine lost in the sample lines prior to sample collection. The weekly particulate filters are then combined to form monthly composites for gross alpha analysis. The weekly particulate filters are also combined to form quarterly composites for strontium-89 and strontium-90 analyses. Two quarterly composites per year are analyzed for Iron-55; the Iron-55 analysis is not required by the ODCM, but is driven by site procedure.
C. Liquid Effluents
- 1. Batch Releases Prior to the release of liquid from a waste tank, a sample is collected and analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. To demonstrate compliance with the concentration requirements addressed in Section II.C.1 above, the measured radionuclide concentrations are compared with the allowable MPCs; dilution in the discharge conduit is considered, and an allowable release rate is verified.
The total activity released in each batch is determined by multiplying the volume released by the concentration of each radionuclide. The actual volume released is based on the difference in tank levels before and after the release. A proportional composite sample is also withdrawn from each release. These composite samples are used for monthly tritium and gross alpha analyses. The composite samples are also used for Iron-55, Nickel-63, Strontium-89, and Strontium-90 analyses that are performed quarterly by an offsite laboratory.
Batch discharges of secondary (normally uncontaminated) waste streams are also monitored for radioactivity. No activity (excluding tritium) is normally detected in these secondary waste streams.
- 2. Continuous Releases To account for activity from continuous releases, a sample is collected and analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. The measured radionuclide concentrations are compared with the allowable MPC concentrations in the discharge conduit, and an allowable release rate is verified.
When steam generator blowdown is discharged to the circulating water conduits, it is sampled and gamma isotopic analysis is performed at a minimum once per week. These results are multiplied by the actual quantity of blowdown to determine the total activity released. The weekly sample is also used to prepare monthly composites for tritium analysis.
During the monitoring for primary-to-secondary leakage low levels of tritium have been detected in the Turbine Building sumps. This water is sampled and analyzed for principal gamma emitting radionuclides weekly and composited. The composite sample is analyzed at least monthly for tritium.

CALVERT CLIFFS NUCLEAR POWER PLANT AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOACTIVE EFFLUENT RELEASE ANNUAL REPORT - 2018 The results are multiplied by the actual quantity of liquid released to determine the total activity released.
D. Estimation of Total Error Total error for all releases was estimated using, as a minimum, the random counting error associated with typical releases. In addition to this random error, the following systematic errors were also examined:
- 1. Liquid
- a. Error in volume of liquid released prior to dilution during batch releases.
- b. Error in volume of liquid released via steam generator blowdown.
- c. Error in amount of dilution water used during the reporting period.
- 2. Gases
- a. Error in main vent release flow.
- b. Error in sample flow rate.
- c. Error in containment purge release flow.
- d. Error in gas decay tank pressure.
Where errors could be estimated they are usually considered additive.
E. Meteorological Data A summary of required meteorological data is included in the Annual Radiological Environmental Operating Report and is not included in this report.
F. Reporting and Recordkeeping for Decommissioning In accordance with 10 CFR 50.75.g, each licensee shall keep records of information important to the safe and effective decommissioning of the facility in an identified location until the license is terminated by the Commission. If records of relevant information are kept for other purposes, reference to these records and their locations may be used. Information the Commission considers important to decommissioning consists of records of spills or other unusual occurrences involving the spread of contamination in and around the facility, equipment, or site. These records may be limited to instances when significant contamination remains after any cleanup procedures or when there is reasonable likelihood that contaminants may have spread to inaccessible areas as in the case of possible seepage into porous materials such as concrete. These records must include any known information on identification of involved nuclides, quantities, forms, and concentrations.
To assist in the decommissioning, and to provide early and advance detection of any unmonitored releases of radioactive material from the site, groundwater is routinely sampled. These groundwater samples are analyzed for gamma and tritium activity. Sample size and/or count times are adjusted to achieve analytical sensitivities lower than the environmental LLDs for gamma emitters (listed in ODCM Table 4.12-1 ). The established LLD limit for tritium is 200 pCi/1. The 2018 analysis results for tritium and gamma are listed in the Annual Radiological Environmental Operating Report and are not included in this report.
