ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT EXECUTIVE

SUMMARY

The Annual Environmental and Effluent Release Report (AEERR) details the results of environmental and effluent monitoring programs conducted at the Perry Nuclear Power Plant (PNPP) from January 01 through December 31, 2001. This report meets all of the requirements in PNPP Technical Specifications, the Environmental Protection Plan (EPP), and Regulatory Guide 1.2 1. It incorporates the requirements of the Annual Radioactive Effluent Release Report (ARERR),

the Annual Radiological Environmental Operating Report (AREOR) and the Annual Environmental Operating Report (AEOR). Report topics include radioactive effluent releases, radiological environmental monitoring, land use census, clam/mussel monitoring, herbicide use, and special reports. The results of the environmental and effluent programs, for 2001, indicate that the operations of the Perry Nuclear Power Plant did not result in any significant environmental impact.

RADIOACTIVE EFFLUENT RELEASES During the normal operation of a nuclear power plant, small quantities of radioactivity may be released to the environment in liquid and gaseous effluents. Radioactive material may also be released as solid waste. PNPP maintains a comprehensive program to control and monitor the release of all radioactive materials from the site in accordance with all Nuclear Regulatory Commission (NRC) release regulations.

The dose to the general public from the plant's liquid and gaseous effluents was below the applicable regulatory limits. The calculated hypothetical maximum individual whole body dose potentially received by an individual resulting from PNPP liquid effluents was 2.3 IE-03 mrem (0.077 % of the applicable limit). The calculated hypothetical maximum individual whole body dose potentially received by an individual resulting from PNPP gaseous effluents was 6.16E-03 mrem (0.12% of the applicable limit). The summation of the hypothetical maximum individual dose from effluents in 2001 is equivalent to < 0.1 % of the total dose an individual living in the PNPP area receives from all sources of radiation.

Shipments of solid waste consisted of waste generated during water treatment; radioactive material generated during normal daily operations and maintenance, and irradiated components. PNPP complied with all regulations governing radioactive shipments in 2001, making shipments of solid radioactive waste to a licensed burial site.

During 2001, there were two (2) ODCM Controls non-compliance conditions and two (2) abnormal releases:

On March 15, 2001, the liquid radwaste discharge high flow monitor was inoperable for greater than 30 days as a result of a bad micrometer switch connector. Since this connector was not expected to fail, it was not maintained as a spare part. The monitor was out of service for 34 days. Compensatory measures, as required by ODCM Table 3.3.7.9-1, Action 112, were implemented, until the flow monitor was returned to service on March 22, 2001.

On June 02, 2001, the Emergency Service Water total flow monitor, 1P45-N0271, was out of service for greater than 30 days. Erratic flow indications resulted in the monitor being out of service for 48 days. Compensatory measures, as required by ODCM Table 3.3.7.9-1, Action 113, were implemented, until the flow monitor was returned to service on June 19, 2001.

On August 20, 2001, tritium was detected in the Turbine Building I-VAC (M35) condensate drains system effluent. The most probable cause for this abnormal release was the recycling of radioactive gaseous treatment system effluent vent discharges back into the M35 system via the air intake. There was minimal dose consequence to the any member of the general public.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT

On December 03, 2001, a Unit I containment vacuum breaker was inadvertently opened during the performance of a surveillance. The inadvertent opening of the vacuum breaker resulted in a potential airborne radioactive effluent release to the environment. The dose contribution as a result of this abnormal release had minimal consequence to any member of the general public.

RADIOLOGICAL ENVIRONMENTAL MONITORING The Radiological Environmental Monitoring Program (REMP) was established in 1981 to monitor the radiological conditions in the environment around PNPP. The REMP is conducted in accordance with PNPP Technical Specifications and the Offsite Dose Calculation Manual (ODCM). This program includes the collection and analysis of environmental samples and evaluation of results.

The REMP was established at PNPP six (6) years before the plant became operational. This pre operational program was designed to provide data on background radiation and radioactivity normally present in the area. PNPP has continued to monitor the environment during plant operation by collecting and analyzing samples of air, precipitation, milk, fish, produce, water and sediment, as well as by measuring radiation directly. [

Of the 1376 radiological environmental samples collected in 2001, there were approximately 3300 radioactivity analyses performed. The results of the REMP indicate the adequacy of the control of the release of radioactivity in the effluents from PNPP. These results also demonstrate that PNPP complies with all applicable federal regulations. The REMP results are divided into four sections:

atmospheric monitoring, terrestrial monitoring, aquatic monitoring, and direct radiation monitoring:

Samples of air were collected to monitor the radioactivity in the atmosphere. The 2001 results were similar to those observed for the pre-operational and operational programs from prior years. Only natural background environmental radioactivity was detected.

Terrestrial monitoring included the analysis of milk, produce, and vegetation. The PNPP ODCM does not require vegetation or soil samples to be included in the monitoring program.

The results of the sample analyses in 2001 indicated concentrations of radioactivity similar to that found in previous years. Analyses of other terrestrial samples also detectedL concentrations of radioactivity similar to those observed in previous years, and indicated no build-up of radioactivity attributable to the operation of PNPP.

I

Aquatic monitoring included the collection and analyses of water, fish, and shoreline sediments. The 2001 analytical results for water and fish sample showed normal background radionuclide concentrations. The results of sediment sample analyses indicated that the cesium radioactivity was similar to previous years. The average concentration of cesium-137 in the sediment was 611.91 pCi/kg, which is within the maximum value of 864 pCi/kg I

established since 1981. In 1999, a sediment sample of the northwest drain impoundment (sampling location #64) was analyzed to contain 62 pCi/kg of cobalt-60. During 2001, enhanced monitoring activities continued within the boundaries of the impoundment. The I

cobalt-60 remained centered within the organic material located at the top of the spillway, with little or no activity found farther upstream.

Direct radiation measurements showed no change from previous years. The indicator locations averaged 56.26 mrem/year and control locations averaged 54.92 mrem/year. In 2001, radiation dose in the area of PNPP was statistically similar to the radiation dose measured at locations greater than ten (10) miles away from the Plant.

I Based on these results, during 2001, the operation of the PNPP resulted in no significant increase in the radionuclide concentrations observed in the environment. L Executive Summary Page 2

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT LAND USE CENSUS In order to estimate radiation dose attributable to the operation of PNPP, the potential pathways through which public exposure can occur must be known. To identify these exposure pathways, an Annual Land Use Census is performed as part of the REMP. During the census, PNPP personnel travel every public road within a five (5) mile radius of the plant to locate key radiological exposure pathways. These key pathways include the nearest resident, garden, and milk animal in each of the sixteen meteorological sectors. The information obtained from the census is entered into a computer program, which is used to assess the hypothetical dose to members of the public.

CLAMIMUSSEL MONITORING Clam and mussel shells can clog plant piping and components that use water from Lake Erie. For this reason, sampling for clams and mussels has been conducted in Lake Erie in the vicinity of PNPP since 1971. The monitoring is specifically for Corbicula (Asiatic clams),. since their introduction into the Great Lakes, in 1981, and for Dreissena (zebra mussels), since their discovery in Lake Erie, in 1989. Since no Corbicula have ever been found at PNPP, routine Corbicula monitoring will provide early detection capability, when this pest species arrives at PNPP. The Dreissena program includes both monitoring and control and is directed at minimizing the mussel's impact on plant operation. As in past years, this program has successfully prevented Dreissena from causing any operational problems at PNPP.

HERBICIDE USE The use of herbicides on the PNPP site is monitored to ensure compliance with Ohio Environmental Protection Agency (OEPA) requirements and to protect the site's natural areas. Based on the results of on-site herbicide applications, and weekly general site inspections, herbicide use has not had a negative impact on the environment around the plant.

SPECIAL REPORTS Significant environmental events (for example, spills, releases), noncompliance with environmental regulations [e.g., Ohio Environmental Protection Agency (OEPA) discharge limits], and changes in plant design or operation that affect the environment are reported to regulatory agencies as they occur. These special reports are also summarized annually in this report.

On February 19, 2001, the OEPA was notified of a leak from the Circulating Water (CW) system.

This leak was in an underground pipe, which released approximately 15,000 gallons to the environment. This water contained Ferroquest LP7202 at concentrations greater than the discharge limits. The CW system was shut down for repairs and the Ferroquest LP7202 was neutralized to meet Permit limits.

On October 02, 200 1, the OEPA was notified that the permitted discharge limit for Clam-Trol was exceeded during a planned zebra mussel chemical treatment. The chemical injection rate was reduced and detoxification was increased to return the Clam-Trol to within the Permit limit. The zebra mussel chemical treatment test procedure was revised to improve the detoxification method and to require more detoxification chemical during future treatments.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT INTRODUCTION Nuclear energy provides an alternative energy source, which is readily available and has very limited impact upon the environment. To more fully understand nuclear energy as a source of generating electricity, one must understand basic radiation concepts and its occurrence in nature.

I RADIATION FUNDAMENTALS Atoms are the basic building blocks of all matter. Simply described, atoms are made up of positively and negatively charged particles, and particles which are neutral. These particles are called protons, electrons, and neutrons, respectively. The relatively large protons and neutrons are packed together in the center of the atom called the nucleus. Orbiting around the nucleus are one or more smaller electrons. In an electrically neutral atom, the positively-charged protons in the nucleus balance the negatively charged electrons. Due to their dissimilar charges, the protons and electrons have a strong attraction for each other, which helps hold the atom together. Other attractive forces between the protons and neutrons keep the densely packed protons from repelling each other, and preventing the nucleus from breaking apart.

Atoms with the same number of protons in their nuclei make up an element. The number of neutrons in the nuclei of an element may vary. Atoms with the same number of protons but different numbers of neutrons are called isotopes. All isotopes of the same element have the same chemical properties and many are stable or non-radioactive. An unstable or radioactive isotope of an element is called a radioisotope, or radionuclide. Radionuclides contain an excess amount of energy in the nucleus, which is usually due to an excess number of neutrons. L Radioactive atoms attempt to reach a stable, non-radioactive state through a process known as radioactive decay. Radioactive decay is the release of energy from an atom's nucleus through the emission of radiation. Radionuclides vary greatly in the frequency with which their atoms release radiation. The length of time an atom remains radioactive is defined in terms of its half-life. Half life is defined as the time required for a radioactive substance to lose half its activity through the process of radioactive decay. Half-lives vary from millionths of a second to millions of years. The typical half-life for radionuclides released from the plant is approximately five years.

RADIATION AND RADIOACTIVITY Radioactive decay is a process in which the nucleus of an unstable atom becomes more stable by spontaneously emitting energy. Radiation refers to the energy that is released when radioactive decay occurs within the nucleus. This section includes a discussion on the three (3) primary forms of radiation produced by radioactive decay. [

Alpha Particles Alpha particles consist of two protons and two neutrons and have a positive charge. Because of their /

charge and large size, alpha particles do not travel very far when released (less than 4 inches, in air).

They are unable to penetrate any solid material, such as paper or skin, to any significant depth.

However, if alpha particles are released inside the body, they can damage the soft internal tissues because they deposit all their energy in a small area.

Beta Particles Beta particles are essentially free electrons, which usually carry a negative electrical charge. They are much smaller than alpha particles and travel at nearly the speed of light. Thus they can travel for L

longer distances than alpha particles. External beta radiation primarily affects the skin. Because of their electrical charge, paper, plastic or thin metals can stop beta particles.[

Radiological Effluent Releases Page 4

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Gamma Rays Gamma rays are bundles of electromagnetic energy, called photons, which behave as though they were particles. They are similar to visible light, but of a much higher energy. Gamma rays can travel long distances in air and are often released during radioactive decay, along with alpha and beta particles. Potassium-40 is an example of a naturally occurring radionuclide found in all humans that decays by emitting a gamma ray.

Interaction with Matter When radiation interacts with other materials, it affects the atoms of those materials principally by knocking the negatively charged electrons out of orbit. This causes an atom to lose its electrical neutrality and become positively charged. An atom that is charged, either positively or negatively, is called an ion and the radiation is called ionizing radiation.

UNITS OF MEASURE Some of the units of measure used in this report require explanation.

Activity Activity is the number of atoms in a material that decay per unit of time. Each time an atom decays, radiation is emitted. The curie (Ci) is the unit used to describe the activity of a material and indicates the rate at which the atoms are decaying. One curie of activity indicates the decay of 37 billion atoms per second. Smaller units of the curie are often used in this report. Two common units are the microcurie (taCi), one millionth of a curie, and the picocurie (pCi), one trillionth of a curie. The mass, or weight, of radioactive material, which would result in one (1) curie of activity, depends on the disintegration rate. For example, one gram of radium-226 is equivalent to one (1) curie of activity. It would require about 1.5 million grams of natural uranium, however, to equal one (1) curie.

Dose Biological damage due to alpha, beta, and gamma radiation may result from the ionization caused by these types of radiation. Some types of radiation, especially alpha particles, which causes dense local ionization, can result in much more biological damage for the same energy imparted than does gamma or beta radiation. Therefore, a quality factor must be applied to account for the different ionizing capabilities of various types of ionizing radiation. When the quality factor is multiplied by the absorbed dose, the result is the dose equivalent, which is an estimate of the possible biological damage resulting from exposure to any type of ionizing radiation. The dose equivalent is measured in terms of the Roentgen Equivalent Man (rem). When discussing environmental radiation effects, the rem is a large unit. Therefore, a smaller unit, the millirem (mrem) is often used. One mrem is equivalent to 1/1000 of a rem.

LOWER LIMIT OF DETECTION Sample results are often reported as below the Lower Limit of Detection (LLD). The LLD for an analysis is the smallest amount of radioactive material that will show a positive result for which there can be a 95% confidence that radioactivity is present. This statistical parameter is used as a measure of the sensitivity of a sample analysis. When a measurement is reported as less than the LLD

(<LLD), it means that no radioactivity was detected. Had radioactivity been present at (or above) the stated LLD value, it statistically would have been detected. The NRC has established LLD values for environmental and effluent sample analyses.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT BACKGROUND RADIATION Background radiation is a natural part of nature. Natural radioactive decay also occurs in the soil, water, air, and space. Common sources of radiation that contribute to the natural background radiation includes: the decay of radioactive elements in the earth's crust, a steady stream of high energy particles from space (called cosmic radiation), naturally-occurring radioactive isotopes in the human body like potassium-40, phosphate fertilizers (phosphatesthe decay and of radioisotopes uranium are often foundusedtogether in medical procedures, in nature), falloutman-made fo nuclear weapons testing, and even household items like smoke detectors. In the United States, a person's average annual exposure from background radiation is 360 mrem, and is due to the sources shown in Figure 1 [Source: National Council on Radiation Protection and measurements].

Many radionuclides are present in the environment due to sources such as cosmic radiation and fallout from nuclear weapons testing. These radionuclides are expected to be present in many of the environmental samples collected in the vicinity of PNPP. Some of the radionuclides normally present include:

Beryllium-7, present as a result of the interaction of cosmic radiation with the upper atmosphere, I

Potassium-40, a naturally occurring radionuclide normally found in humans and throughout the environment, and 3

Radionuclides from nuclear weapons testing fallout, including tritium and cesium-137. These radionuclides may also be released in minute amounts from nuclear facilities.

Beryllium-7 and potassium-40 are especially common in REMP samples. Since they are naturallyU occurring and are expected to be present, positive results for these radionuclides are not discussed in the section on the 2001 Sampling Program results. These radionuclides are included, however, in Appendix A, 2001 Inter-Laboratory Cross-Check Comparison Program Results.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT RADIOACTIVE EFFLUENT RELEASES INTRODUCTION The source of radioactive material in a nuclear power plant is the generation of fission products (e.g., noble gas, iodine, and particulate) or neutron activation of water and corrosion products (e.g., tritium and cobalt). The majority of the fission products generated remain within the nuclear fuel pellet and fuel cladding. Fission products that escape from the fuel cladding, as well as the majority of the activated corrosion products, are removed by plant processing equipment.

During the normal operation of a nuclear power plant, small amounts of radioactive material are released in the form of solids, liquids, and gases. PNPP was designed, and is operated in such a manner as to control and monitor these effluent releases. Effluents are controlled to ensure any radioactivity released to the environment is minimal and within all regulatory limits. Effluent release programs include the operation of monitoring systems, in-plant sampling and analysis, quality assurance, and detailed procedures covering all aspects of effluent monitoring.

The liquid and gaseous radioactive waste treatment systems at PNPP are designed to collect and process these wastes in order to remove most of the radioactivity. Effluent monitoring systems are used to provide continuous indication of the radioactivity present and are sensitive enough to measure several orders of magnitude lower than the applicable release limits. This monitoring equipment is equipped with alarms and indicators in the plant control room. The alarms are set to provide warnings to alert plant operators when radioactivity levels reach a small fraction of actual limits. The waste streams are sampled and analyzed to identify and quantify the radionuclides being released to the environment.

Gaseous effluent release data is coupled with on-site meteorological data in order to calculate the dose to the general public. Devices are maintained at various locations around PNPP to constantly sample the air in the surrounding environment. Frequent samples of other environmental media are also taken to determine if any radioactive material deposition has occurred. The REMP program is described in detail in the next section.

Generation of solid waste is carefully monitored to identify opportunities for minimization. Limiting the amount of material taken into the plant, sorting material as radioactive or non-radioactive, shredding and compacting, or incinerating waste once it is identified help to lower the volume of radioactive solid waste generated. Solid waste is shipped to a licensed burial site.

REGULATORY LIMITS The Nuclear Regulatory Commission has established limits for liquid and gaseous effluents that comply with:

Title 10 of the Code of Federal Regulations, Part 20 (Standards for Protection Against Radiation)

[10CFR20], Appendix B; Title 10 of the Code of Federal Regulations, Part 50 (Domestic Licensing of Production and Utilization Facilities) [IOCFR50], Appendix I; and Title 40 of the Code of Federal Regulations, Part 190 (Environmental Radiation Protection Standards for Nuclear Power Plants) [40CFR 190].

These limits were incorporated into the PNPP Technical Specifications, and subsequently into the PNPP Offsite Dose Calculation Manual (ODCM). The ODCM prescribe the maximum doses and dose rates due to radioactive effluents resulting from the operation of PNPP. These limits are defined in several ways to limit the over-all impact on persons living near the plant. Since there are Radiological Effluent Releases Page 7

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT no other fuel cycle sources near the PNPP the 40CFRl190 limits, which are described below, were not exceeded in 2001.

The 40CFR190 limit for total direct-radiation dose is 25 mrem. For 2001, the total whole body dose to a member of the general public, considering all sectors, was 4.3E-01 mrem. This value was determined by summing the annual whole body doses from liquid and gaseous radioactive effluents, the annual gaseous organ dose (refer to Table 8) and the maximum, direct-radiation dose. Since the direct radiation dose, as determined by TLD, was indistinguishable from natural background (refer to Figure 8), it was not included in the calculation.

Liquid Effluents The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to the concentrations specified in 10CFR20, Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases, as required by the ODCM. For dissolved or entrained noble gases, the concentration shall be limited to 2.OE-04 gCi/mL of total activity. These values are the maximum effluent concentrations.

The dose or dose commitment to a member of the public from radioactive materials in liquid effluents released to unrestricted areas shall be limited to the following:

During any calendar quarter:

Less than or equal to 1.5 mrem to the whole body, and Less than or equal to 5 mrem to any organ.

During any calendar year:

Less than or equal to 3 mrem to the whole body, and[

Less than or equal to 10 mrem to any organ.

Gaseous Effluents Dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site boundary shall be limited to the following:

Noble gases:

Less than or equal to 500 mrem per year to the whole body, and Less than or equal to 3000 mrem per year to any organ.'

Iodine-13 1, iodine-133, tritium, and all radionuclides in particulate form with half lives greater than eight days:

Less than or equal to 1500 mrem per year to any organ Air dose due to noble gases to areas at, and beyond the site boundary, shall be limited to the following: L During any calendar quarter:

Less than or equal to 5 mrad for gamma radiation, and Less than or equal to 10 mrad for beta radiation.

During any calendar year:

L Less than or equal to 10 mrad for gamma radiation, and Less than or equal to 20 mrad for beta radiation.

Radiological Effluent Releases Page 8

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Dose to a member of the public from iodine-131, iodine-133, tritium, and all radionuclides in particulate form with half lives greater than eight days in gaseous effluents released to areas at and beyond the site boundary shall be limited to the following:

Less than or equal to 7.5 mrem to any organ per any calendar quarter, and Less than or equal to 15 mrem to any organ per any calendar year.

The PNPP ODCM does not contain a concentration reference for gaseous effluents. For this reason, effluent concentrations are not used to calculate maximum release rates for gaseous effluents.

RELEASE

SUMMARY

Effluents are sampled and analyzed to identify both the type and quantity of radionuclides present.

This information is combined with effluent path flow measurements to determine the composition, concentration, and dose contribution of the radioactive effluents.

Liquid Effluents The PNPP liquid radioactive waste system is designed to collect and treat all radioactive liquid waste produced in the plant. The treatment process used for radioactive liquid waste depends on its physical and chemical properties. It is designed to reduce the concentration of radioactive material in the liquid by filtration to remove suspended solids and demineralization to remove dissolved solids. Normally, the effluent from the liquid radioactive waste system is returned to plant systems.

To reduce the volume of water stored in plant systems, however, the processed liquid effluent may be discharge from the plant via a controlled release. In this case, effluent activity and dose calculations are performed prior to, and after discharging this processed water to Lake Erie to ensure regulatory compliance and dose minimization principals are maintained. This section does not include information on the abnormal tritium release related to the Turbine Building HVAC Condensate Drains (M3 5) System. The abnormal release is fully discussed under the "Special Reports" section.

Liquid radioactive waste system effluents may be intermittently released, which are considered to be "batch" releases. Table I provides information on the number and duration of these releases for 2001.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Gaseous Effluents Gaseous effluents are made up of fission and activation gases, iodine and particulate releases. The fission and activation gas releases are primarily a result of containment purge operations, small steam leaks, and off-gassing during plant start up and shut down operations. The iodine and particulate releases are primarily a result of small steam leaks. Gaseous effluents from PNPP exit the plant via one of four effluent vents. Each of these four effluent vents contains radiation detectors that continuously monitor the air to ensure that the levels of radioactivity released are well below regulatory limits. Samples are also collected and analyzed on a routine basis to ensure regulatory compliance and dose minimization principals are maintained. The majority of gaseous effluents released from PNPP are considered continuous and at ground level.

A summation of all gaseous radioactive effluent releases is given in Table 4. If a radionuclide was not present at a level "greater than or equal to the LLD" (>_LLD), then the value is expressed as "less than the LLD" (<LLD). In each case, the measured LLDs either met or were below the levels required by the PNPP ODCM.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT METEOROLOGICAL DATA The Meteorological Monitoring System at PNPP consists of a 60-meter tower equipped with two independent systems for measuring wind speed, wind direction, and temperature at both 10-meter and 60-meter heights. The tower also has instrumentation to measure dew point and barometric pressure. Data is logged from the tower through separate data loggers, and transmitted to a common plant computer. This system compiles the data and calculates a variety of atmospheric parameters, communicates with the Meteorological Information Dose Assessment System (MIDAS), and sends data over communication links to the plant Control Room.

DOSE ASSESSMENT The maximum concentration for any radioactive release is controlled by the limits set forth in Title 10 of the Code of Federal Regulations, Part 20 (10CFR20). Sampling, analyzing, processing, and monitoring the effluent stream ensures compliance with these concentration limits. Dose limit compliance is verified through periodic dose assessment calculations. Some dose calculations are conservatively performed for a hypothetical individual who is assumed to reside on the site boundary at the highest potential dose location all year. This person, called the "maximum individual", would incur the maximum potential dose from direct exposure (air plus ground plus water), inhalation, and ingestion of water. vegetation, and fish. Because no one actually meets these criteria, the actual dose receivw a real member of the public is significantly less than what is calculated forI this hypothetical inr ,dual.

Dose calculations for this maximum individual at the site boundary are performed for two cases.

First, they are performed using data for a 360' radius around the plant site (land and water based meteorological sectors), even though some of these sectors are over Lake Erie, which has no permanent residents. The second calculation is performed considering only those sectors around the plant in which people reside (land-based meteorological sectors).

The calculated hypothetical, maximum individual dose values at the site boundary are provided in Table 7. This table considers all meteorological sectors around PNPP and provides either the whole body or worst-case, organ dose values. If any radionuclide was not present at a level greater than the

LLD, it was not used in the dose calculations.

This person would receive the maximum dose during the time spent inside site boundary. Because no one actually meets the criteria established for these conservative calculations, the actual dose received by a real member of the public is significantly less than what is calculated for this hypothetical individual. This dose is assessed relative to the offsite dose, and considers dilution, dispersion, and occupancy factors.

The highest hypothetical dose from liquid effluents to a member of the public inside the site boundary is to a person who is fishing on Lake Erie from the shore on PNPP property. The calculations assume that this person will spend 60 hours6.944444e-4 days 0.0167 hours 9.920635e-5 weeks 2.283e-5 months per year fishing, with a liquid dilution factor of 10. The ratio of the exposure pathway to the doses calculated for offsite locations yields the dose values shown in Table 10.

The dose from gaseous radiological effluents is based upon the population that lives within 50 miles of PNPP (2,420,000 people). The dose from liquid radiological effluents is determined for the population that receives drinking water from intakes within 50 miles of PNPP (1,820,000 people).

Annual 9.5E-10 2.5E-09 (1) -- No liquidradioactiveeffluent releases during thisperiod ABNORMAL RELEASES There were two abnormal radioactive release events, during 2001.

Turbine Bldg. HVAC (M35) System Condensate Drains Effluent Tritium Release During routine monitoring of the Turbine Building HVAC (M35) system condensate drains on August 20, 2001, tritium was detected in the effluent. This system was not expected to contain radioactivity, nor was the discharge from this system a radioactive liquid effluent discharge point.

The condensate drains collected condensed moisture entrained in the intake air to the M35 system.

[

By plant design, the condensed moisture from the outside air was discharged to the plant's storm drains as radiologically-clean effluent. The routing of the M35 system condensate drains to the plant's storm drains was implemented to remove a "radioactively clean" source of water from the radioactive liquid treatment system.

In accordance with the PNPP ODCM, this incident was considered an abnormal release. Although believed to be only a few days, the exact duration for the release could not be determined. The I

release was estimated to have started after August 13, 2001, which was the last time the M35 system was sampled and analyzed to have no detectable radioactivity. The immediate corrective action was to route the M35 drains to the radioactive liquid treatment system for processing.

Radiological Effluent Releases Page 16

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT The measured tritium activity of 9.73E-07 J.Ci/mL was 9.7E-02 % of the 10CFR20, Appendix B, Table 2, Column 2, limiting effluent concentration limit. The amount of tritium released over seven (7) days was calculated to be 3.1E-04 Ci. Since these dose values are well below any regulatory limits, this abnormal release (refer to Table 13) had minimal dose consequence to the general public.

Table 13: Turbine Bldg. HVAC Condensate Drain System Abnormal Release ESTIMATED DOSE, ANNUAL % OF ORGAN mrem LIMIT LIMIT Liquid Effluent Whole body 6.30E-05 3.OE+00 2.1E-03 Liver 6.30E-05 1.OE+01 6.3E-04 The most probable cause for this event was the recycling of the radioactive gaseous treatment system effluent vent discharges back into the plant as part of the air intake. Four factors combined to contribute to the apparent causes associated with this event: 1) the gaseous treatment system effluent vents are considered ground-level release points; 2) the atmospheric high humidity and stability (very little wind); 3) tritium build-up in the plant; and 4) the near "zero discharge" policy for radioactive liquid discharges. It is postulated that the low levels of tritium in the effluent vents being short-cycled back into the M35 system intakes, combined with the contributing factors, resulted in the tritium being concentrated in the M35 drains.

The routing of the M35 drains to the storm drains system was to remove a "radioactively clean" source of water from the radioactive liquid treatment system. By reducing the input of "radioactively clean" water into the radioactive liquid treatment system, the need for discharges is significantly reduced, thus reducing the dose impact on the general public. At the time, engineering recognized the potential for radioactive material to enter the storm drains via this path. Monitoring was implemented, and corrective actions put in place should radioactivity be detected.

Unit 1 Containment Vacuum Breaker Inadvertent Opening On December 03, 2001, at 06:58, the Unit 1 containment vacuum breaker 1M17-F0010 was inadvertently opened, which resulted in a potential airborne radioactive effluent release to the environment. The duration of the release was estimated to be 15 seconds, but for calculational purposes, a release duration of 60 seconds was used. This incident was considered an abnormal release in accordance with the PNPP ODCM. As required by the PNPP ODCM, a grab sample was obtained of the Unit I Containment Building atmosphere and analyzed for principal gamma emitters.

Based on the analytical results and an estimated volume released of 4263 cu ft, compliance with the limits for Derived Air Concentration (0.0148 ýXCi/cc) and 10CFR50 (1.19E-04 pCi/cc) was verified.

The dose contributions from this event (refer to Table 14) had minimal dose consequence to the general public. Refer to Appendix D, 2001 Abnormal Gaseous Release Dose Summary and Meteorological Data for compliance data, dose summaries and meteorological data.

the switch for containment vacuum breaker 1M 17-F0040. Opening valve IM 17-FOO10 resulted in an unmonitored release path to the environment. The apparent cause of this event was the result of aI human performance error related to attention to detail. The plant operator was not focused on the required switch manipulations prior to actually performing the evolution.

NON-COMPLIANCES There were two (2) non-compliance to the ODCM Controls requirements in 2001:

Radwaste Discharge Header High Flow Monitor Inoperable Greater Than 30 Days [

The liquid radwaste discharge to ESW header high flow monitor was inoperable for greater than 30 days as a result of a hardware failure. The flow monitor failed on 02/16/2001 due to a bad micrometer switch connector. This connector was not expected to fail, therefore, it was not considered a "critical" spare part or maintained in stock. The replacement connector arrived on-site on 03/17/01, with the monitor being returned to service on 03/22/01. The monitor was inoperable for 34 days. In accordance with Control 3.3.7.9, Action b, the flow monitor was declared inoperable

[

and the compensatory requirements of Table 3.3.7.9-1, Action 113, were implemented.

ESW Total Flow Monitor Inoperable Greater Than 30 Days The Emergency Service Water flow monitor 1P45-N0271 was out-of-service for greater than 30 days as a result of excessive turbulence in the monitor's stillwell, when two ESW pumps are operating.

On 5/02/01, the flow monitor was declared inoperable, when a satisfactory channel check could not be obtained. At that time, the monitor was declared inoperable and Control 3.3.7.9, Action b, was implemented. On 06/19/01, the total flow monitor was declared operable, which meant the flow monitor was inoperable for 48 days. /

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT RADIOLOGICAL ENVIRONMENTAL MONITORING INTRODUCTION The Radiological Environmental Monitoring Program (REMP) was established at PNPP for several reasons. First, it verifies the adequacy of plant design and operation to control radioactive materials and limit effluent releases. Second, it assesses the radiological impact, if any, that the plant has had on the surrounding environment. Third, it ensures compliance with regulatory guidelines. The REMP is conducted in accordance with the PNPP Operating License, Appendix B, Technical Specifications and the ODCM. The Nuclear Regulatory Commission (NRC) established the REMP requirements.

A wide variety of samples are collected as part of the PNPP REMP. The selection of sample types, sampling locations, and sample collection frequency are based on many things. Potential pathways for the transfer of radionuclides through the environment to humans, sample availability, local meteorology, population characteristics, land use and NRC requirements are all considered.

To ensure that the REMP data are meaningful and useful, detailed sampling methods and procedures are followed. This ensures that samples are collected in the same manner and from the same locations each time. All samples are packaged on site, then shipped to an independent vendor laboratory for analysis. The vendor laboratory analyzes the samples and reports results to the PNPP Chemistry Unit staff, the Lake County General Health District, and the State of Ohio Department of Health.

The REMP began in 1981 with 24 direct radiation monitoring locations, four sediment locations, and two fish sampling locations. In 1982, collections of air, water, milk, food products, and feed/silage were added. Vegetation, precipitation and soil were added in 1985. Although the NRC did not require these last three media, they were incorporated into the program to establish baseline data. In 1993, feed/silage sampling was dropped from the program, based on ten years worth of data. For the same reason, strontium analyses were deleted from the program in 1994, gross beta and tritium were deleted from precipitation analyses in 1995, and precipitation sampling was deleted entirely in 1996.

In 1999, grass and soil sampling were dropped from the program. Although not required, the grass, soil and precipitation sampling sites remain available, if future sampling is desired.

SAMPLING LOCATIONS REMP samples are collected at numerous locations, both on site and up to 22 miles away from the plant. Sampling locations are divided into two general categories: indicator and control. Indicator locations are those which would be most likely to display effects caused by plant operation. They are relatively close to the plant. Control locations are those which are considered to be unaffected by plant operation. Typically, they are a greater distance from the plant, in the least prevalent wind directions. Data obtained from the indicator locations are compared with data from the control locations. This comparison allows naturally occurring background radiation to be taken into account when evaluating any radiological impact PNPP may have had on the environment. Table 15, Figure 2, Figure 3 and Figure 4 identify the PNPP REMP sampling locations.

Many REMP samples are collected in addition to those required by the PNPP ODCM. The ODCM requirements for each sample type are discussed in more detail below. Sample types and locations required by the ODCM are shown in Bold in Table 15.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Sample Analysis When environmental samples are analyzed for radioactivity, several types of measurements are performed to provide information about the types of radiation and radionuclides present. The major analyses that are performed are discussed below.

Gross beta activity measures the total amount of beta-emitting radioactivity present in a sample, and acts as a tool to identify samples that may require further analysis. Beta radiation may be released by many different radionuclides. Since beta decay results in a continuous energy spectrum rather than the discrete energy levels, or "peaks", associated with gamma radiation, identification of specific beta-emitting nuclides is much more difficult. Therefore, gross beta activity only indicates whether the sample contains normal, or abnormal amounts of beta-emitting radioactivity; it does not specifically identify the radionuclides present.

Gamma spectral analysis provides more specific information than does the analysis for gross beta activity. Gamma spectral analysis identifies each radionuclide, and the amount of radioactivity, I

present in the sample emitting gamma radiation. Each radionuclide has a very specific "fingerprint" that allows for accurate identification and quantification.j Iodine activity analysis measures the amount of radioactive iodine present in a sample. Some media (for example, air sample charcoal cartridges) are analyzed directly by gamma spectral analysis. With other media (for example, milk), the radioiodines are extracted by chemical separation before being analyzed by gamma spectral analysis.

Tritium activity analysis measures the amount of the radionuclide tritium (H-3) present in a sample.

Tritium is an isotope of hydrogen that emits low-energy beta particles. Tritium occurs naturally and is also man-made.

I Gamma doses received by Thermoluminescent Dosimeters (TLD) while in the field are determined by a special laboratory procedure. Thermoluminescence is a process by which ionizing radiation interacts with the sensitive phosphor material in the TLD. Energy is trapped in the TLD material and can be stored for months or years. This capability provides an excellent method to measure the dose received over long periods of time. The amount of energy that was stored in the TLD as a result ofL interaction with radiation is released by a controlled heating process and measured in a calibrated reading system. As the TLD is heated, the phosphor releases the stored energy as light. The amount of light is directly proportional to the amount of radiation to which the TLD was exposed. The reading analysesprocess alsoon zeroes the TLD and prepares it for reuse.

performed environmental samples collected for theTable PNPP16REMP provides a list of the in 2001.

Sample results are often reported as less than the lower limit of detection (< LLD), which is defined as the smallest amount of radioactive material that will show a positive result for which there can be confidence that radioactivity is present. This statistical parameter is used as a measure of the sensitivity of a sample analysis. When a measurement is reported as < LLD, it means that noI radioactivity was detected at a value above, or equal to the appropriate ODCM table value. The NRC has established LLD values for REMP sample analyses. The vendor laboratory for REMP sample analyses was able to comply with those values in 2001.

operational data from previous years, and control location data. The results for each sample type are discussed below and compared to historical data to determine if there are any observable trends. All results are expressed as concentrations. Refer to Appendix B, 2001 REMP Data Summary Reports for a detailed listing of these results. The NRC requires special reporting whenever sample analysis results exceed set limits. No values exceeded these reporting levels in 2001.

Program Changes There were no changes to the REMP Program during 2001.

Missed Samples On occasion, samples cannot be collected. This can be due to a variety of events, including equipment malfunction, animal husbandry practices, or lost shipments. Events may also occur which prevent a sample from being collected in the normal way, or prevent a complete sample from being collected. The drying period for goats is an annual occurrence, since unlike cows, goats cannot produce milk year-round. Missing TLDs may be the result of vandalism. When vandalism has been identified as a recurring problem, the TLD is relocated. If the loss of a TLD is determined to be a single or unusual event, it is not normally relocated. Table 17 provides information on samples missed during 2001.

The PNPP ODCM requires five locations (four indicator and one control). Air sampling pumps are used to draw continuous samples at a rate of approximately two cubic foot per minute. The air is drawn through glass fiber filters (to collect particulate material) and a charcoal cartridge (to adsorb iodine).

The samples are collected on a weekly basis, 52 weeks a year, from each of seven air sampling stations. Six (6) of these locations are within four miles of the plant site; the seventh is used as a control location and is eleven miles from PNPP.

On occasion, air sample locations can experience power losses associated with storms and/or malfunctioning equipment. On September 08, 2001, location # 35 experienced such a power loss, which required the complete replacement of the underground transformer that powered the sample station. Although the sample station was without power for 4 days, the sample collected was sufficient to provide the required analytical results.

Air samples are -zed weekly for gross beta activity and radioiodine activity. The air samples are also analyzed b-, na spectral analysis quarterly. A total of 364 for air particulate and 364 air radio-iodine samp*.., were collected and analyzed in 2001.

Gross beta activity was detected in all air samples and ranged up to 0.06 pCi/mi3. The annual average gross beta activity at both indicator and control locations was 0.02 pCi/m 3. Historically, the concentration of gross beta in air has been essentially identical at indicator and control locations.

Figure 5 reflects the average gross beta activity for 2001 and the previous years.

Except for naturally occurring beryllium-7, no radionuclides were identified in the gamma spectral analysis above the LLD values. Iodine- 131 was not detected in any sample above the LLD of 0.05 pCi/m3 .

Year 0 Indicator *Control Terrestrial Monitoring Collecting and analyzing samples of milk, food products and vegetation provides data to assess the build-up of radionuclides that may be ingested by humans. The historical data from soil and vegetation samples provides information on the atmospheric radionuclide deposition. The PNPP ODCM requires neither vegetation nor soil samples.

Milk Samples of milk are collected once each month from November through March, and twice each month from April through October. Sampling is increased during the summer because animals usually feed outside on pasture and not on stored feed. The PNPP REMP includes three (3) milk locations (two within five miles of the plant, and one control). Since the milk sampling locations did not meet the requirements of the ODCM (no milk-producing animals located within the required areas), food product sampling (discussed below) was performed. Milk was collected from the available locations, even though they did not meet the ODCM requirements. If new locations that meet the ODCM requirements are identified in the future, they will be added to the program.

Milk samples are analyzed by gamma spectral analysis for radioiodines and other radionuclides. A total of 51 milk samples were collected in 2001. Iodine was not detected above the LLD of 0.75 pCiIL in any of the samples. The concentrations of all radionuclides, except naturally occurring potassium-40, were below LLDs in all samples collected. The results for potassium-40 were similar at indicator and control locations, as expected.

Food Products Food products can provide a direct pathway to humans by ingestion. They can absorb radionuclides from atmospheric deposition on soil or from irrigation water drawn from a lake or pond receiving airborne or liquid effluents. Also, radionuclides in the soil may be absorbed by the roots of the plants and become incorporated into the edible portions. Because there is not a sufficient number of milk sampling locations, the PNPP REMP is required to include two food product indicator locations and one control location. Food products are collected monthly during the growing season from five farms in the vicinity of PNPP. The control location for food products is 16.2 miles from PNPP.

A total of seventy-seven (77) food product samples were collected and analyzed by gamma spectral analysis in 2001. Five (5) food products were collected which included: beet greens, turnip greens, chinese cabbage, swiss chard and kale. Beryllium-7 and potassium-40, naturally-occurring Radiological Environmental Monitoring Page 27

I ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT radionuclides, were found in several samples, as expected. No other radionuclides were detected above the required LLDs.

Aquatic Monitoring Radionuelides may be present in Lake Erie from many sources other than the PNPP. These sources include atmospheric deposition, run-off/soil erosion, and releases of radioactivity in liquid effluents from hospitals, universities or other industrial facilities. These sources provide two forms of potential radiation exposure, external and internal. External exposure can occur from contact with water or shoreline sediments, while internal exposure can occur from either direct ingestion of radionuclides or the transfer of radionuclides through the aquatic food chain. Direct ingestion can occur from drinking the water, while the transfer via the aquatic food chain occurs from the eventual consumption of aquatic organisms, such as fish. To monitor these pathways, PNPP samples water, shoreline sediments, and fish.

Water I Water is sampled from five locations along Lake Erie in the vicinity of the PNPP as required by the PNPP ODCM. Samples from three locations are collected using composite sample pumps. The pumps are designed to collect water at regular intervals and composite it in a sample container. The containers are emptied monthly and the samples shipped to the laboratory for analysis. Samples I

from two locations are collected weekly and combined. Each month the combined sample is shipped for analysis.

Fifty six (56) water samples were collected and analyzed for gross beta activity and gamma spectral analysis in 2001. From these monthly samples, a quarterly composite sample was obtained and analyzed for tritium activity. 5 Gross beta activity was detected in nine (9) of the fifty-six (56) samples collected. None (0) of the twelve (12) control samples, however, were above the LLD values listed in the ODCM. The detectable (i.e., above the lab LLD value) gross beta activity ranged from 3.06 pCi/L to 4.15 pCiL.

Referring to Figure 6, the annual average gross beta activity was 3.67 pCi/L at the indicator locations I

and 3.32 pCi/Lat the control location, using the mean of values >LLD. The significant difference between the pre- 1988 data and post-1988 data has been attributed to a change in vendor laboratories in 1987/1988. A comprehensive explanation for the observed difference is provided in the 1988 I

Radiological Environmental Monitoring Page 28

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT There were no radionuclides detected by gamma spectral analysis above the LLD. Tritium was not detected above the LLD value in any of the twenty (20) samples analyzed. These results are well within the range of those measured in previous years, which have ranged from below the LLD to 2,200 pCi/L.

Sampling lake bottom sediments can provide an indication of the accumulation of particulate radionuclides which may lead to internal exposure to humans through the ingestion of fish, the re suspension into drinking water, or as an external radiation source to fishermen and swimmers from shoreline exposure. Although the PNPP ODCM requires only one location, sediment is sampled twice each year from seven (7) locations. Two (2) of the sampling locations are also fish sampling locations. Sediment samples from offshore are collected using a hand dredge. Near shore samples are collected using a scoop. Fourteen (14) sediment samples were collected in 2001 and analyzed by gamma spectrometry.

The predominant radionuclide detected by gamma spectral analysis was naturally-occurring potassium-40. Potassium-40 has been detected in all samples, since the program began in 1981.

Cesium- 137 activity was detected in five (5) of the fourteen (14) samples collected and ranged from 210.75 pCi/kg to 1388.10 pCi/kg. The annual average cesium-137 activity was 486.90 pCi/kg at the indicator locations and 799.43 pCi/kg at the control location.

Year-to-year variations in the lake bottom sediment sample activities is expected and beyond the control of PNPP. For example, cesium-137 activity variations (refer to Figure 7) in the control locations from year-to-year may be contributed to:

1. The movement of sediment on the lake bottom due to wave action and currents, and

2. Sampling in nearly the same location approximately 41/2 miles off-shore, even with GPS, is extremely difficult.

In 1999, a sediment sample from sample location #64 (northwest drain impoundment) was analyzed to contain 62.00 pCi/kg of cobalt-60. This activity was just above the detection limit. In 2000, ten (10) additional sample locations were established within the impoundment to identify the boundary of the cobalt-60 activity and to support supplemental monitoring activities. For 2001, sampling activities were performed on May 3 0 ", June 6t, October 8 " and October 15". Referring to Radiological Environmental Monitoring Page 29

<10.0 pCi/kg to 267.0 pCi/kg. The cobalt-60 activity at sampling location #64 continues to be centered within the organic material at the top of the spillway, with little or no activity found farther upstream.

Fish Fish are analyzed primarily to quantify the dietary radionuclide intake by humans, and secondarily to serve as indicators of radioactivity in the aquatic ecosystem. Fish are collected from two locations, twice each year as required by the ODCM. Important sport and commercial species are targeted, and only the fillets are sent to the laboratory for analysis. A scientific collecting permit is obtained annually from the Ohio Department of Natural Resources for fish sampling.

Twenty-eight (28) fish samples were collected and analyzed by gamma spectral analysis in 2001.

Fourteen (14) species of fish were represented, including walleye, drum, carp, white and redhorse sucker, steelhead, stone and channel catfish, white perch, gizzard shad, smallmouth bass, rock bass, white bass and coho salmon. As expected, naturally occurring potassium-40 was found in all samples. No other radionuclides were detected above the LLD.

Direct Radiation Monitoring Thermoluminscent Dosimeter (TLD)

Environmental radiation is measured directly at twenty-eight locations around the PNPP site, two of which are control locations. The locations are positioned in two rings around the plant as well as at the site boundary. The inner ring is within a one-mile radius of the plantsite; the outer ring is four to five miles from the plant. The control locations are over ten miles from the plant in the two least prevalent wind directions. Each location is equipped with three TLDs, two of which are changed quarterly and one is changed annually.

A total of 251 TLDs were collected and analyzed in 2001. This includes all 224 collected on a quarterly basis and twenty seven (27) of (28) collected annually. During the 4 th quarter collection of TLDs on 1/3/02, all TLDs (quarterly and annual) were collected with the exception of the annual TLD for location #55. A search of the immediate area was performed but possible recovery was hampered by deep snow. It was determined that the location had not been vandalized, but that strong Radiological Environmental Monitoring Page 30

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT winds had dislodged the TLD from its mounting point. Annual TLDs are not required per the ODCM and are used for supplemental data only.

In 2001, the annual average dose for all indicator locations was 56.26 mrem, and 54.92 mrem for all control locations. Referring to Figure 8, the average quarterly dose for all indicator locations was 15.95 mtem, and 15.97 mrem for all control locations. Prior to 1988, the TLD results were higher due to a change in the vendor laboratory services. A comprehensive explanation of this difference was provided in the 1988 Annual Environmental Operating Report.

A typographical error was discovered in the 2000 report between Figure 8 and its respective text (refer to Appendix E, 2000 AEERR Corrections). Figure 8 reflected that the 2000 average quarterly TLD control dose was 15.2 mrem vs. the text reference of 9.1 mrem. The correct value was 15.2 mrem, as reflected in the graph.

ca5 (3indicator Year *Control Conclusion Sediment samples continue to confirm cobalt-60 in the northwest drain impoundment. The activity level wasjust above the detection limits. Samples taken upstream did not find any additional activity or the source. Additional monitoring is being performed to monitor this location. An environmental evaluation determined that there would be less impact upon the environment by leaving this material in place. Atmospheric monitoring results were consistent with past results. The prevalent radionuclide in air was beryllium-7 which is naturally occurring. Naturally occurring potassium-40 was detected in all terrestrial samples, as expected. Cesium-137 was detected in sediment samples and is the result of fallout from weapons testing. The concentrations were similar to those measured in previous years and are not related to plant operation.

Finally, direct radiation measurements are consistent with past data.

Radiological Environmental Monitoring Page 31

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT j Inter-Laboratory Cross-Check Comparison Program Introduction The purpose of the Inter-laboratory Cross-Check Comparison Program (ICCCP) is to provide an independent check on the vendor laboratory's analytical procedures. Samples with a knownI concentration of specific radionuclides are provided to the vendor laboratory. The vendor laboratory measures and reports the concentration of specified radionuclides. The known values are then compared to the vendor results. Results consistently outside established acceptance criteria indicate a need to check instruments or procedures. Regulatory Guide 4.15 specifically required that I

contractor laboratories that performed environmental measurement participate in the EPA's Environmental Radioactivity Laboratory Inter-Comparison Studies Program, or an equivalent program.

I The EPA's program is not longer funded and no longer offered. The reason that the EPA program was referenced in the regulatory guide is that the EPA standards were traceable to National BureauL of Standards (now known as National Institute Standard Technology). In response to this problem, Teledyne (our vendor lab) incorporated a program offered by Environmental Resource Associates (ERA Company), which covered the same analyses in the same matrix at the same frequency as the EPA program. The ERA Company has received NIST accreditation for its program, as an equivalent program. In addition to comparison cross checks performed with the ERA Company, the vendor laboratory routinely monitors the quality of their analyses by:

Analyzing "spiked" samples (samples with a specific quantity of radioactive material present in them),

Participating in the Department of Energy's Mixed Analyte Performance Program (MAPEP),

and

+ Participating in the Environmental Measurements Laboratory Quality Assessment Program (EML).

In the 2000 Annual Report, Table A- I (refer to Appendix E, 2000 AEERR Corrections), the "spiked" water sample STW-868 referenced the vendor laboratory results for Ra-228 as 5.6+/-1.0 pCi/L vs. the control limit of 1.3-3.2 pCi/L. Although re-analysis results were identified, no explanation was given for the reason the control limit was not met. Per the vendor lab (Environmental Inc.), the chemistry reanalysis results and the gamma spectroscopy results confirmed that their detectors were functioning properly. The vendor's investigation determined that the probable cause was a possible error in dilution. Sufficient spiked sample was not available to have the dilution steps re-performed. 4 Conclusion Appendix A, 2001 Inter-Laboratory Cross-Check Comparison Program Results, includes results from both the above referenced programs and the ERA Company cross-check program. One (1)I water sample analyzed for Sr-89 was determined to be outside the ERA program control limits.

Delay in processing possibly caused the resulting analysis. Reanalysis determined that the Sr-89 sample was within program control limits. Referring to the In-house "spike" sample results, one (1) /

water sample analyzed for Ra-228 was lost during the analysis, causing the results to be outside the control limits on the low side. Insufficient sample remained to perform a re-analysis. One other "spiked" sample, Cs-137 in milk, was suspect due to its results being outside the control limits on the high side. A new Cs-137 spike was prepared and analyzed the following month. This value was within the accepted criteria. Two (2) In-house "blank" milk samples analyzed for Sr-90 were found to be outside the program control limits of<1.0 pCi/L liquid. Low levels of Sr-90 remain in the environment and concentrations of (1-5 pCi/I) found in milk is not unusual. The sample's results of Radiological Environmental Monitoring Page 32 l

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT 1.18+/- 0.35 pCi/i and 1.09+/- 0.36 pCi/l respectively, fall within these parameters. For the MAPEP Program, one (1) soil sample analyzed for Am-241 was included as a "false positive" with no activity expected. The resulting analysis was <0.8 Bq/l. In the ERL program, a soil sample analyzed for Bi-212 was found outside the control limits on the high side. The Vendor Laboratory determined that naturally occurring radium and thorium daughters contained in the shield background contributed to the slightly elevated results. To adjust for these occurrences, the vendor lab performs quarterly background readings and calibrates its equipment accordingly. All other analysis results performed under these programs were within the control limits established.

LAND USE CENSUS Introduction Each year a land use census, which is required by Section 3/4.12.2 of the PNPP ODCM, is conducted to identify the locations of the nearest milk animal, garden (of greater than 500 square feet), and residence in each of the meteorological sectors that is over land. Information gathered during the Land Use Census is used for off-site dose assessment and to update sampling locations for the Radiological Environmental Monitoring Program. The census is conducted by traveling all roads within a five-mile radius of the plant site, and recording and mapping the location of the nearest resident, milk animal, and vegetable garden. The 2001 Land Use Census, which was conducted August 8 th and 9 th, provided the garden, residence and milk animal locations tabulated in Table 19 and depicted in Figure 9. Note that the W, WNW, NNW, NW, N, and NNE sectors extend over Lake Erie, and therefore, are not included in the survey.

Discussions and Results In general, the predominant land use within the census area continues to be rural/agricultural. The 2001 Land Use Survey used the 1999 survey map produced by the Commercial Survey Co. of Cleveland. GPS units were used for a more accurate and detailed identification of media locations.

Table 19 identifies the nearest residences, by sector, to the PNPP. The table is updated annually to reflect any changes identified during the annual Land Use Census. For 2001, there was only one change required. This change identified the construction of a new home, which resulted in a new "nearest residence" in the ESE sector.

ANNuAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT CLAM/MUSSEL MONITORING INTRODUCTION I

Sampling for benthic macro-invertebrates (clams and mussels) has been conducted in Lake Erie in the vicinity of PNPP, since 1971. The clam/mussel program currently focuses on two species:

Corbiculafluminea(Asiatic clam) and Dreissenapolymorpha(zebra mussel).

CORBICULA PROGRAM Monitoring specifically for Corbicula was initiated in response to a NRC bulletin and concerns of the I

Atomic Safety and Licensing Board. The 2001 monitoring was done as part of the Environmental Protection Plan (Operating License, Appendix B). The program consists of visually inspecting the raw water systems, whenever they are opened for maintenance. The purpose of this program is to detect Corbicula, should it appear at PNPP.

No Corbicula have ever been found in any sample collected from PNPP or from Lake Erie in the vicinity of PNPP. Two Corbicula were found in a sample collected from the Eastlake plant in June, 1987. No Corbicula have been found in any other sample collected since that time. A more detailed program history can be found in the 1986 and 1987 PNPP Annual Environmental Operating Reports.

Monitoring In 2001, samples were collected from the Service Water (SW), Emergency Service Water (ESW) and Circulating Water (CW) systems at PNPP. All samples were collected by Ponar hand dredge, I

hand scoop, or scraper. They were examined for asiatic clam shells and fragments. In addition to sample collections, plant components that use raw water are inspected whenever opened for maintenance or repair. Sample collection/inspection dates are listed in Table 22.

Clam/Mussel Monitoring Page 36 -I

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Conclusions The sample collected in June, 1987, was the only indication of Corbicula in the vicinity of PNPP.

Although the presence of Corbicula was detected at the Eastlake Power Plant, it has not been demonstrated that their presence has created any operational problems there, or at PNPP.

DREISSENA PROGRAM Dreissena, or Zebra mussels were first discovered at PNPP in September, 1988. The initial collection of 19 mussels was made as part of the Corbicula monitoring program. The Dreissena monitoring program began in 1989, with monitoring and testing. The current control program was designed and implemented in 1990.

Monitoring In addition to visually inspecting the plant's raw water systems when they are opened for maintenance or repair, monitoring methods include the use of commercial divers, side-stream monitors, and plankton nets. Commercial divers monitor mussel infestation during the inspection of forebays, basins, and the intake and discharge structures. Divers have also been used to take underwater videotapes of the water basins and intake tunnel. Sidestream monitors are flow-through containers that receive water diverted from plant systems, and are normally used in three in-plant locations during the mussel season. The sidestream monitors are fitted with slides and inspected for veliger settlement. A plankton net was used on a limited basis in 2001 to help trend veligers during the spawning season.

Treatment Chemicals used for mussel control in 2001 included chlorine and a commercial molluscicide. The chlorine is intermittently injected into the plant service water, emergency service water, and circulating water systems by metering sodium hypochlorite into each system's influent. Sodium sulfite is added at the plant discharge structure for dechlorination prior to entry into Lake Erie.

The use of a commercial molluscicide requires approval by the Ohio Environmental Protection Agency (OEPA). The chemical selected for use at the PNPP in 2001 was alkyl-dimethyl-benzyl ammonium chloride. One treatment was applied in October, 2001. The active ingredients were detoxified by adsorption onto bentonite clay, prior to discharge into Lake Erie.

Results The effectiveness of the intermittent chlorination treatment has been determined in several ways.

First, visual inspections of raw water-system components are conducted when systems are open during maintenance or repair. In addition, settlement monitors were inspected for new settlement.

No live settlement has been found in any plant component to date.

The effectiveness of the application of the commercial molluscicide was measured by observing mortality of mussels placed in a flow-through container placed in plant service water and subjected to the chemical treatment. The observed mortality rate in the flow-through container was >99%. To date, PNPP has had no problems related to zebra mussels.

CONCLUSIONS Perry Nuclear Power Plant has taken the approach that the best method for avoiding problems with zebra mussels is preventive treatment of plant water systems. The current program of monitoring and chemical treatment will be continued to minimize the possibility that PNPP will experience future problems due to zebra mussels.

I ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT HERBICIDE APPLICATIONS [

Herbicides are used sparingly on the PNPP site. A request must be made to, and approved by the PNPP Chemistry Unit prior to spraying to ensure that only approved chemicals are used, and only in approved areas.

In 200 1, three (3) general herbicide requests were initiated for spraying applications. Each application was in compliance with the Ohio Environmental Protection Agency's rules and1 regulations. There were no adverse environmental impacts observed during weekly site environmental inspections as a result of these applications. The only herbicide approved for use in the Owner-Controlled Area was Round-Up. For each application, the type of weed to be treated dictated the herbicide concentration to be used. Table 23 provides detailed documentation for each h

application in 2001. The volume represents the quantity of herbicide applied, after dilution.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT SPECIAL REPORTS NON-COMPLIANCES NPDES Permit The National Pollutant Discharge Elimination System (NPDES) permit is issued by the Ohio Environmental Protection Agency (OEPA). It establishes monitoring requirements and limits for discharges from the PNPP. It also specifies the locations from which the plant is allowed to discharge.

On February 19, 2001, the OEPA was notified of a leak from the Circulating Water (CW) system.

This leak was in an underground pipe, which released approximately 15,000 gallons to the environment. This water contained Ferroquest LP7202 at concentrations greater than the discharge limits. The CW system was shut down for repairs and the Ferroquest LP7202 was neutralized to meet Permit limits.

On October 02, 2001, the OEPA was notified that the permitted discharge limit for Clam-Trol was exceeded, during a zebra mussel chemical treatment evolution. The chemical injection rate was reduced and detoxification was increased to return the Clam-Trol to within the Permit limit. The zebra mussel chemical treatment test procedure was revised to improve the detoxification method and to require more detoxification chemical during future treatments.

Environmental Protection Plan The Environmental Protection Plan (EPP), which is a part of the PNPP Operating License, requires a non-radiological environmental monitoring and reporting program be established at the PNPP.

There were no instances of an EPP non-compliance identified in 2001.

UNREVIEWED ENVIRONMENTAL QUESTIONS All proposed changes to the PNPP design or operation, as well as tests or experiments, must be evaluated for potential environmental impacts in accordance with the EPP and administrative quality assurance procedures. In 2001, these reviews ensured that no changes to the facility or programs were performed, which could have resulted in an adverse environmental impact. Therefore, there were no potentially significant unreviewed environmental questions identified.

NON-ROUTINE REPORTS There were two (2) non-routine reports submitted in 2001.

On March 13, 2001, the OEPA was contacted to request permission to bypass Circulating Water in accordance with NPDES permit requirements.

On June 14, 2001, the OEPA was notified that a bypass had occurred during routine maintenance of the Emergency Service Water System. This caused untreated Lake Water to flow to the ground.

Authorization was given by the OEPA to continue the bypass for maintenance.

Al Appendix A Page 40

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services, Midwest Laboratory has participated in inter-laboratory cross-check comparison programs since the formulation of it's quality control program in December, 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher, or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

The results in Table A-I were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request. The U.S. Environmental Protection Agency, Office of Research and Development, National Exposure Research Laboratory, Characterization Research Division-Las Vegas, Nevada, conducted this program.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of cross-check testing with Teledyne Brown Engineering are also listed.

Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years is available upon request.

Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years is available upon request.

Table A-5 lists results of the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years is available upon request.

The results in Table A-6 were obtained through the participation in the Mixed Analyte Performance Evaluation Program.

The results in Table A-7 were obtained through the participation in the Environmental Measurement Laboratory Quality Assessment Program.

ANNUAL ENVIRONMENTAL AND EFFLUENT RELEASE REPORT Twenty-seven (27) fish samples were collected and analyzed by gamma spectral analysis in 2000.

Sixteen (16) species of fish were represented, including walleye, drum, carp, quilback sucker, spotted sucker, white sucker, redhorse sucker, round gobi, steelhead, catfish, yellow perch, white perch, gizzard shad, smallmouth bass, rock bass and white bass. As expected, naturally occurring potassium-40 was found in all samples. No other radionuclides were detected above the LLD.

Direct Radiation Monitoring Thermoluminscent Dosimeter (TLD)

Environmental radiation is measured directly at twenty-eight locations around the PNPP site, two of which are control locations. The locations are positioned in two rings around the plant as well as at the site boundary. The inner ring is within a one-mile radius of the plant site; the outer ring is four to five miles from the plant. The control locations are over ten miles from the plant in the two least prevalent wind directions. Each location is equipped with three TLDs, two of which are changed quarterly and one is changed annually.

A total of 252 TLDs were collected and analyzed in 2000. This included 224 collected on a quarterly basis, and twenty-eight (28) collected annually. In 2000, the annual average dose for all indicator locations was 59.59 mrem, and 56.97 mrem for all control locations. Referring to Figure 8, the average quarterly dose for all indicator locations was 15.2 mrem, and F1 15.2 mrem for the control locations. Prior to 1988, the TLD results were higher due to a change in vendor laboratory services. A comprehensive explanation of this difference was provided in the 1988 Annual Environmental Operating Report.

Ž5 20-m lý dia r Yea ar C o ntrolI Conclusion Sediment samples continue to confirm cobalt-60 in the northwest drain impoundment. The activity level was just above the detection limits. Samples taken upstream did not find mny additional activity or the source. Additional monitoring is being performed to monitor this location. An environmental evaluation determined that there would be less impact upon the environment by leaving this material in place. Atmospheric monitoring results were consistent with past results. The prevalent radionuclide in air was beryllium-7 which is naturally CindAppendi YEa occurring. Naturally occurring potassium-40 Pager57 was detected in all terrestrial samples, as expected. Cesium- 137 was detected in sediment samples and is the result of fallout from weapons testing. The concentrations were similar to those measured in previous years and are not related to plant operation.

Finally, direct radiation measurements are consistent with past data.
