ABSTRACT 

This report describes radioactive effluents from commercial nuclear power plants (NPPs) in the 

United States. This information was reported by the licensees for radioactive discharges that 

occurred in 2007. The report provides information relevant to the potential impact of NPPs on 

the environment and on public health. The report includes information on: 

• radionuclides in liquid and gaseous effluents from NPPs and 

• radiation doses to the public from NPP effluents. 

This report is a summary of the effluent data reported by the NPPs. To view all the information 

contained in the Annual Radioactive Effluent Release Reports from each NPP, visit the Nuclear 

Regulatory Commission (NRC) Web site at http://www.nrc.gov/about-nrc/radiation.html. 

The radionuclide and radiation dose data in this report are intended to provide the reader with a 

means to quickly characterize the effluents from any NPP. The data presented are considered 

by the NRC to be particularly relevant to the potential impact of NPPs on public health and the 

environment. The radionuclides selected for inclusion are either the most predominant in 

radioactive effluents or are particularly useful indicators of overall releases. The radiation doses 

in the report are those most directly associated with potential public health impact. 

For purposes of comparison, the data also include the median (midpoint) radionuclide 

concentrations, as well as the applicable NRC dose limits and design objectives. Finally, the 

results of the National Council on Radiation Protection’s assessment of radiation exposure to 

the U.S. population also are included so the reader can compare the dose from NPP effluents 

relative to natural background and other sources of radiation exposure.

INTRODUCTION 

1.1 PURPOSE 

This report describes radioactive effluents from commercial nuclear power plants (NPPs) in the 

United States during calendar year 2007. It is based on an extensive amount of information 

submitted to the Nuclear Regulatory Commission (NRC) by all U.S. NPP licensees. The original 

information was submitted by the NPPs in their Annual Radioactive Effluent Release Reports 

(ARERRs) and comprises several thousand pages of data. These reports may be viewed in 

their entirety on the NRC Web site (http://www.nrc.gov/about-nrc/radiation.html). 

For the years between 1972 and 1993, this type of annual information was condensed in a 

tabular format and published as a large volume of raw information (Ref. 1-22). An evaluation of 

the practice of generating annual reports revealed the need for a more concise summary report 

that presented the information in a more intuitive, graphic format (Ref. 23). 

The purpose of this report is to condense an extremely large volume of technical information 

into a few graphs and tables from which the reader can quickly, if broadly, characterize the 

effluents from any U.S. NPP. These graphs and tables are designed to provide easily 

understandable information for the public at large, while also providing experienced 

professionals with enough information to evaluate trends in industry performance and to identify 

potential performance issues for individual power plants. Those users wanting more extensive 

and detailed information are encouraged to retrieve the original ARERRs from the NRC Web 

site. 

1.2 SCOPE 

This report summarizes data from all NPPs that were in commercial operation between 

January 1, 2007 and December 31, 2007. A list of NPPs for which information is included in this 

report is provided in Table 1.1.

1-6 Annual Report 2007

The NRC uses the information on radioactive releases to ensure NPPs are operated within 

regulatory requirements and consistent with the objective of maintaining radiation doses as low 

as is reasonably achievable (ALARA). For this summary report, only information submitted with 

regard to NRC reporting requirements and guidance is included. 

The Big Rock Point, Haddam Neck, Humboldt Bay, Lacrosse, Maine Yankee, Rancho Seco, 

Trojan, Yankee-Rowe and Zion 1 and 2 reactor sites are shutdown and are not collocated with 

an operating reactor. The data from these shutdown reactors are not included in the tables in 

this report. The Dresden 1, Millstone 1, and Three Mile Island 2 reactors are shutdown and are 

collocated with one of more operating reactors. For these shutdown reactors, the licensee 

reports data for the shutdown unit separately from the operating units, and the results from 

these shutdown reactors are not included in this report. For the Indian Point 1 and San Onofre 1 

reactor sites, which are shutdown and collocated beside two operating units, the licensee 

reports the sum of the effluents from the shutdown unit with one (or both) of the operating units. 

For these shutdown reactors, the effluent data are included with (and attributed to) one or more 

of the operating units in this report. 

1.3 SOURCE OF DATA 

Each commercial nuclear power plant in the United States is authorized by the NRC to release 

small amounts of radioactive materials to the environment as specified in the licensing 

documents for the plant. NRC regulations require each NPP to establish and maintain a 

program for monitoring radioactive effluents (10 CFR 50.36 and 10 CFR 50, Appendix I, Section 

IV.B) and to report these effluents in an Annual Radioactive Effluent Release Report (10 CFR 

50.36a) (Ref. 24). Licensees submit their reports to the NRC with content and format in 

accordance with Regulatory Guide 1.21 (Ref. 25). 

The information included in this document was obtained from the licensees’ ARERRs. Individual 

licensee reports are available in the NRC Public Document Room, One White Flint North, 11555 

Rockville Pike (first floor), Rockville, Maryland 20852, phone 1-800-397-4209 or 301-415-4737; 

in local Public Document Rooms located near each licensed facility; and on the Internet as 

posted on the NRC’s public Web site at http://www.nrc.gov/about-nrc/radiation.html. 

The data from these reports are entered into a database that is maintained by the NRC. The 

public may access this database through an NRC Web site (http://www.reirs.com/effluent/). The 

data are entered into the database as they are reported by each site. 

1.4 LIMITATIONS OF THE DATA 

Some NPPs have more than one reactor unit located at a site. If the licensee reports data 

separately for each reactor unit, those data are reflected in this report as reported by the 

licensee. Because some licensees are allowed to operate multi-unit sites with a common 

radioactive waste processing system, the NRC allows these licensees to report total effluents 
Radioactive Effluents from Nuclear Power Plants 1-7 

from the site instead of reporting the totals from each reactor unit. This complicates the task of 

presenting the effluent information in a manner that allows both (1) a direct comparison of one 

reactor unit to another, and (2) a direct comparison of each reactor unit to NRC limits and 

regulations. 

For purposes of presentation in this report, the data are normalized on a per-unit basis. For 

multi-unit sites where the effluents are from a common radioactive waste system, the effluents 

are divided equally between the units in operation during that year. For example, Calvert Cliffs 

has two units (1 and 2) with a common radioactive waste processing system. For this report, the 

total effluents for Calvert Cliffs were split equally between Unit 1 and Unit 2. In the case of 

Beaver Valley, the licensee reports gaseous effluents from four sources: Unit 1, Unit 2, a 

common plant vent, and a common building vent. In this case, the releases from the common 

vents are split equally between Unit 1 and Unit 2, and the totals for each unit then are 

calculated. In those cases where the licensee does not report unit-specific data, the NRC has – 

for purposes of presentation in this report – split the data on a unit-specific basis. This may 

affect either the radionuclide data or the dose data (or both). The affected NPPs and the type of 

data affected are listed in table 1-2. 

Although there are other methods of normalizing effluent data (e.g., on the basis of thermal or 

electrical power generation), the unit-based method selected (1) is most intuitive, (2) is most 

directly comparable with the NRC required design objectives, and (3) is easily derived from the 

effluent data supplied by the licensee. This approach satisfies a primary objective for this report: 

to allow the reader to quickly formulate reasonable comparisons between reactors and with the 

regulatory limits. It should be noted, however, that the actual unit contributions to a common 

multi-unit release might be different than the equal distribution calculated with this approach. 

Care has been taken to assure that the information contained in this report accurately reflects 

the information provided by the licensees. The report includes licensees’ corrections submitted 

to the NRC up to the time of publication. However, if licensees submit amendments to the data 

in accordance with NRC regulatory guidance, the NRC reserves the right to update the data in 

future reports. For the most current data, the reader should use the most recent versions of the 

NPPs’ ARERRs and the NRC’s annual summary report, which are available on the NRC Web 

site.

DESCRIPTION OF THE DATA 

2.1 AIRBORNE AND LIQUID EFFLUENTS 

The effluent data are presented in Section 4 as tables and graphs. Tables 4.1 through 4.12 list 

the total measured activities of selected radionuclides in gaseous and liquid effluents during 

2007. These data are illustrated in Figures 4.1 through 4.12. If there is no value listed in a 

particular cell in a table, it is because the licensee indicated the radionuclide was not detected at 

that NPP. In those cases, the corresponding graph will not contain information on that 

radionuclide at that NPP. 

For comparison purposes, median values are included on some tables and graphs. The median 

is a statistical estimate of the midpoint of the data. It is a method of estimating a central or 

typical value while avoiding bias caused by extremely high or low values in the data set. All sites 

are included when calculating the medians, even those sites for which no measurable release of 

a particular radionuclide is reported. If the majority of reactors did not detect a nuclide, the 

median will be blank. 

The tables and graphs are organized by reactor type: boiling water reactors (BWRs) and 

pressurized water reactors (PWRs). The tables and graphs are further subdivided into liquid and 

gaseous effluents. Finally, the data are subdivided into effluent radionuclide categories. 

In order to present the airborne and liquid effluent data in a manner that is both useful and 

concise, only selected radionuclides are included in the tables and graphs of this report. The 

radionuclides included are listed by effluent category in Tables 2.1 and 2.2. 

The unit used for calculating and reporting effluent activity is the curie (Ci), a traditional unit for 

reporting radioactivity in the United States. Other countries report radionuclide activity in units of 

becquerels (Bq). One curie equals 3.7E+10 (3.7 x 1010) becquerels.

Not Presented in this Report 

The radionuclides highlighted in this report are good indicators of total radioactive releases from 

the site, and they can provide additional information about operational practices at the site. For 

example, although there are more than 11 radionuclides in the category of “fission and 

activation gases,” only 3 (Kr-85, Xe-133, and Xe-135) were selected for inclusion in this report. 

These three were chosen because as their activity increases, the activity of other fission and 

activation gases typically increases as well. Conversely, if the activity of these three 

radionuclides is very low, the activity of other fission and activation gases tends to be low also. 

In addition, the ratios of the activities of selected radionuclides can provide insights into fuel 

performance, radioactive waste system operation, and general radioactive waste handling 

practices at a site. The interested reader wanting to see all radionuclides released from NPPs is 

encouraged to review the detailed, site-specific ARERRs on the NRC Web site.

2.2 RADIATION DOSE TO THE PUBLIC 

Each licensee calculates radiation doses from radioactive effluents in accordance with 

requirements of 10 CFR 50, Appendix I, (Ref. 24) based on: 

1. actual measurements of the radioactive materials released to the environment, 

2. models of how radionuclides are dispersed and diluted in the environment, 

3. models of how radionuclides are incorporated into animals, plants, and soil, and 

4. biokinetic models of human uptake and metabolism of radioactive materials. 

These models are designed to calculate the doses to the individuals closest to the NPP or the 

individuals who may be exposed to the highest concentrations of radioactive materials from 

radioactive effluents. This is often referred to as the maximum exposed individual. The 

parameters and assumptions used in these calculations typically include conservative 

assumptions that tend to overestimate the calculated exposures. As a result, the actual doses 

received by real individuals are often much less than those calculated. Guidance for these 

calculations is provided in NRC Regulatory Guide 1.109, and licensees have incorporated this 
2-4 Annual Report 2007

guidance into their Offsite Dose Calculation Manuals (ODCM) (Ref. 26). ODCMs are available in 

the NRC Public Document Room and in local Public Document Rooms (e.g., public libraries) 

located near each NPP. The interested reader may refer to these documents for additional 

information about dose calculations. 

The traditional unit for reporting radiation dose in the United States is the millirem (mrem). Other 

countries report radiation dose in units of sieverts (Sv). One millirem equals 0.00001 sievert. 

The number 0.00001 is often represented in scientific notation as 1 x 10-5 or 1E-05. 

Once the doses are calculated as described in the preceding paragraphs, the calculated doses 

are compared to the operating limits for a NPP. Licensees have established operating limits for 

plant systems to control the amounts of radioactive materials released from NPPs. The NRC 

requires these operating limits to be established in accordance with the design objectives in 10 

CFR 50, Appendix I (Ref. 24). These operating limits are designed to ensure radioactive 

effluents from NPPs are kept as low as is reasonably achievable (ALARA). It should be 

understood that these are operating limits for plant systems and are not safety limits. If a 

licensee would exceed one of these operating limits, they are required to take corrective actions 

to ensure the plant systems are functioning as designed. Maintaining the design functions of 

plant systems is critical to ensure radioactive releases do not exceed the dose limits in 10 CFR 

20 (which are federal safety limits) (Ref. 27). For purposes of comparison, the operating limits 

are set to a small fraction (typically about 3%) of the federal safety limits. Licensees have 

incorporated several different operating limits into their ODCMs as required by their Technical 

Specifications to satisfy NRC regulatory requirements. 

Radiation doses from plant effluents are summarized in Section 4 (Tables 4.13 through 4.16

and Figures 4.13 through 4.16). These graphs and figures contain the annual organ doses (for 

gaseous and liquid effluents), the annual total body doses (for liquid effluents), and the 

corresponding operating limits. These doses are measures of the potential impact of NPP 

effluents on public health and the environment. For multi-unit sites, the operating limits are 

established on a per-unit basis. If there is no value listed in a particular cell of a table, it is 

because the value was not reported by the licensee. In such cases, the corresponding graph will 

not contain dose information for that NPP. Although only the annual organ doses and the annual 

total body doses are included in this report, other doses calculated by the NPPs are included in 

the individual NPP ARERRs, available on the NRC Web site. 

2.3 OTHER SOURCES OF RADIATION DOSE TO THE U.S. POPULATION 

For comparison with NPP effluents, this section provides a perspective on the doses that 

Americans typically receive on average from natural and background radiation. 

In March 2009, the National Council on Radiation Protection and Measurements (NCRP) 

published Report No. 160 as an update to the 1987 NCRP Report No. 93, Ionizing Radiation 

Exposure of the Population of the United States (Refs. 28, 29). Report No. 160 describes the 
Radioactive Effluents from Nuclear Power Plants 2-5 

doses to the U.S. population from all sources of ionizing radiation for 2006, the most recent data 

available at the time the report was written. The report also includes information on the 

variability of those doses from one individual to another. The NCRP estimated that the average 

person in the United States receives the equivalent of about 620 mrem of radiation dose each 

year. NCRP Report No. 160 describes each of the sources of radiation that contribute to this 

dose, including: 

1. naturally-occurring sources (natural background) such as cosmic radiation from space, 

terrestrial radiation from radioactive materials in the earth, and naturally occurring 

radioactive materials in food people eat and air people breathe; 

2. medical sources from diagnosis and treatment of health disorders using radioactive 

pharmaceuticals and radiation-producing equipment; 

3. consumer products; 

4. industrial processes, security devices, educational tools, and research activities; 

5. exposures of workers that result from their occupations. 

Figure 2.1 is a pie chart showing the relative contributions of these sources to radiation dose to 

the U.S. population. Larger relative contributors to dose are represented by proportionally larger 

slices of the pie. Doses to the public from nuclear power generation are included in the industrial 

category; doses to workers from nuclear power generation are included in the category of 

occupational dose. 

Doses to the public due to effluents from NPPs are less than 0.1% of what the average person 

receives each year from all sources of radiation. Doses to workers from occupational 

exposures, including those received from work at NPPs, also are less than 0.1% of the average 

dose to a member of the public from all sources.

Section 3 

SUMMARY 

The effluent data from 2007 have been compiled and reported in the following section. The 

information contained in this report characterizes liquid and gaseous effluents from all United 

States nuclear power plants (NPPs) in commercial operation for calendar year 2007. Although 

all NPPs released some amount of radioactive materials in 2007, none of the effluents from any 

NPP exceeded any NRC limit, any NRC design objective, or any of the licensees’ operating 

limits for radioactive effluents. 

The effluent data provided in this report are considered by the NRC to be particularly relevant to 

the potential impact of the NPPs on public health and the environment. The radionuclides 

highlighted in this report are good indicators of the total radioactive releases from the site and 

they provide additional information about operational practices at a site. The radiation doses in 

this report are those most directly associated with potential public health impact from radioactive 

effluents. 

The statistical medians of the effluent values, the corresponding operating limits, and the results 

of NCRP’s assessment of radiation exposure to the U.S. population are provided for comparison 

to the effluent data. Comparisons between NPPs should be approached with caution because 

differences in fuel conditions, fuel cycle length, radwaste processing equipment, reactor types, 

reactor ages, electrical outputs, and operating conditions can have an effect on radioactive 

effluents. 

More complete and detailed information, including copies of the NPP Annual Radioactive 

Effluent Release Reports, is available to the public on the NRC Web site.

Radioactive Effluents from Nuclear Power Plants 6-1 

Section 6 

GLOSSARY 

Activity or radioactivity: The rate of radioactive decay of a radionuclide, measured in the 

traditional unit of the curie (Ci) or the international standard unit of the becquerel (Bq). 

Background (radiation): Radiation from cosmic sources; naturally occurring radioactive material, 

including radon (except as a decay product of source or special nuclear material); and global 

fallout as it exists in the environment from the testing of nuclear explosive devices and from past 

nuclear accidents such as Chernobyl that contribute to background radiation and are not under 

the control of the licensee. Background radiation does not include radiation from source, 

byproduct, or special nuclear materials regulated by the Nuclear Regulatory Commission. 

Effluent discharge, radioactive discharge: The portion of an effluent release that reaches an 

unrestricted area. 

Effluent release, radioactive release: The emission of an effluent. 

Exposure pathway: A mechanism by which radioactive material is transferred from the (local) 

environment to humans. There are three commonly recognized exposure pathways: inhalation, 

ingestion, and direct radiation. 

Fission and activation gases: The noble (chemically non-reactive) gases formed from the 

splitting (fission) of the uranium-235 isotope in a nuclear reactor or the creation of radioactive 

atoms from non-radioactive atoms (activation) by the capture of neutrons or gamma rays that 

were released during the fission process. 

Gaseous effluents: Airborne effluents. 

Iodines/Halogens: The measured radioactive isotopes of iodine or of other non-metal elements 

in group 17 of the Periodic Table of Elements. Licensees might report any combination of the 

iodine isotopes I-131, I-132, I-133, I-134, and I-135, as well as other halogens such as bromine82 (Br-82). 

Maximum exposed individual: Individuals characterized as maximum with regard to food 

consumption, occupancy, and other usage of the region in the vicinity of the plant site. As such, 

they represent individuals with habits that are considered to be maximum reasonable deviations 

from the average for the population in general. Additionally, in physiological or metabolic 

respects, the maximum exposure individuals are assumed to have those characteristics that 

represent the averages for their corresponding age group in the general population. 
6-2 Annual Report 2007

Member of the public (10 CFR 20): Any individual except when that individual is receiving an 

occupational dose. 

Monitoring: The measurement of radiation levels, concentrations, surface area concentrations or 

quantities of radioactive material and the use of results of these measurements to evaluate 

potential exposures and doses. 

Noble gas: One of six noble gases (helium, neon, argon, krypton, xenon and radon) with an 

oxidation number of 0 that prevents it from forming compounds readily. All noble gases have the 

maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), 

making them stable. 

Particulates: Radioactive materials entrained in the gaseous effluent that are not included in any 

other effluent category. 

Site boundary: That line beyond which the land is neither owned, nor leased, nor otherwise 

controlled by the licensee. 

Tritium: The radioactive isotope of hydrogen (H-3).
