SUMMARY
NJ The Brunswick Nuclear Plant is operated by Carolina Power & Light Company under a license granted by the Nuclear Regulatory Commission. Provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, Brunswick Nuclear Plant Technical Specifications, and the Brunswick Nuclear Plant Offsite Dose Calculation Manual establish the requirements of the Radiological Environmental Monitoring Program. This report provides the results of the Radiological Environmental Monitoring program from January 1,1996 through December 31, 1996.
The Radiological Monitoring program was established in 1973. Radiation and radioactivity in various environmental media have been monitored for more than 24 years, including more than a year prior to commencing operaion. Monitoring is also provided for controllocations which would not be impacted by operations of the Brunswick Nuclear Plant.
Using these control locations and data collected prior to operation allows comparison of data collected at locations near the Brunswick Nuclear Plant which could potentially be impacted by its operations.
Radiation levels show no measurable change from pre-operational radiation levels.
Monitoring results for environmental media are summarized as follows:
Air-monitoring results are similar or less than the concentrations of radioactivity from pre-operation monitoring. These observations are also consistent with past operational data.
(d,_s')
Milk was unavailable due to no milk animals (goat or cow) currently identified within the environs of the plant; therefore, no exposure pathway exists.
Terrestrial vegetation includes broadleaf vegetation. Results indicate no detectable activities were detected in this sampling media.
Aquatic organism monitoring includes fish and benthic organisms (organisms that live on the bottom of the ocean).
Surface water results indicate no detectable activity.
External radiation dose showed no measurable change from pre-operational data.
The continued operation of the Brunswick Nuclear Plant has not significantly contributed radiation or the presence of radioactivity in the environmental media monitored. The measured concentrations of radioactivity and radiation are well within applicable regulatory limits.

O INTRODUCTION TO NUCLEAR OPERATIONS Carolina Power & Light Company (CP&L) operates an integrated electrical system serving more than one million d, y.yp customers in North Carolina and South Carolina. A system mmh map is provided (Figure #1) that illustrates the area served W
and the location of the nuclear generating units including the Harris (Blue), Brunswick (Green), and Robinson j
(Brown) Nuclear Plants. The service area is more than 30,(XX) square miles and has a population of more than 3,5(X),(XX)
Figure 1: CP&L SERVICE AREA people, The energy sources for electrical generation include I ""*' l '
coal, fuel oil, natural gas, hydro-power, and nuclear fuel. No one energy source is best. Each fuel source has merits and disadvantages. Fossil fuels pose issues associated with clean air including emissions of sulfur dioxide and oxides of nitrogen. Both natural gas and hydro-power are in limited supply.
Nuclear energy is a vital component in a diversified energy mix. In 1996 nuclear energy supplied 38% of Nuclear CP&L's total electrical generation. This nuclear Coal component was generated from four units including the Brunswick Nuclear Plant. The remaining energy Oil & Natural Gas sources were primarily from coal-fired generation, Hydro Power and a very small contribution from oil, natural gas, Figure 2: 1996 ENERGY SOURCES and hydro-power.
BENEFITS OF NUCLEAR POWER Nuclear energy is a viable, clean, safe, and readily available source of energy. The operation of the Brunswick Nuclear Plant results in a very small impact on the environment. Nuclear generation serves a vital role in the operation of the Carolina Power & Light system as well as in the nations electrical needs. Nuclear energy currently supplies more than twenty percent of the nation's electrical energy. It is an important source of electrical energy now and is meeting the growing electrical needs for the future l

l f3 Nuclear energy has the following advantages over other fuel sources:
b The fuel is uranium which is relatively inexnensive when compared with the fuels of coal, o
natural gas, and fuel oil.
Emissions from nuclear stations do act include sulfur dioxide, oxides of nitrogen, or carbon dioxide. Sulfur dioxide is well known as a significant contributor to acid rain leading to acidification of strearns and lakes. Oxides of nitrogen play a key role in the formation of ozone which is a significant pollutant in urbanized air quality. Finally carbon dioxide is a significant green-house gas.
Nuclear energy is safe. Nuclear power in the United states has an excellent safety record, starting with the first commercial nuclear plant in 1957.
l To better understand this source of energy, a basic understanding of radiation, its effects, risk assessment, and reactor operation follow.
RADIATION AND RADIOACTIVITY The Atom All matter consists of atoms. An atom is the smallest unit into which an element can be divided
(~)N
(
and still retain its identity as that element. An atom is made up of a number of different particles. These
/q particles are protons, neutrons, and electrons. Each N
proton is positively charged (+). Each neutron has no
(',,
YN charge. And the electron is negatively charged (-). The
-d
__\\-
heavier particles including protons and neutrons are
/
found in the center of the atom in a very small cluster
[
/ *,
referred to as the nucleus. (The term nuclear refers to this nucleus.) Nearly all the mass of the atom is Figure 3: The Atom found in the nucleus. Electrons orbit the nucleus.
Since the atom is electrically neutral (no charge) the number of protons and electrons in the atom are equal. See Figure 3 a conceptional drawing of an atom. The electrons (red) are shown in orbit around the nucleus. The protons (green), and the neutrons (black) are shown in the nucleus at the center of the atom.
Elements, Isotopes, and Radionuclides Simple substances that cannot be decomposed in any chemical reaction are known as elenwnts.
U 3
Hydrogen, oxygen, iron, chlorine, and uranium are examples of elements. The atoms of such elements differ in the number of protons (also know as the atomic number) in their nucleus. For
)
\\
example the number of protons in each example above is 1 for hydrogen,8 for oxygen,26 for iron,17 for chlorine, and 92 for uranium. The number of neutrons in the nucleus may vary in atoms of the same element. Atoms that contain the same number of protons but a different number of neutrons are referred to as isotopes of that element. An example is the element hydrogen which has three isotopes--one with no neutrons, a second with one neutron, an the third with two neutrons. Isotopes can be unstable (also referred to as radioactive), which means they will readily transform to another isotope and are called radionuclides. Of more than one thousand known isotopes less than twenty-five percent are considered stable. It is important to remember that a significant number of radioactive isotopes occur naturally, When referring to isotopes of an element it is common to refer to the element by the symbol for its name (or the name) followed by the total number of protons and neutrons; for example H-3 or hydrogen-3 describing an atom with one proton and two neutrons.
Radiation Radiation is defined as the conveyance of energy through space. This conveyance may occur in the form of particles, waves, or photons. Some common forms of radiation are sunlight, microwaves or radio waves. These are all examples of non-ionizing radiation. Ionizing radiation differs in its interaction with matter because its energy is capable of removing an
(
clectron from the outer part of an atom resulting in the remaining atom being positively charged and a free electron. There are two types ofionizing radiation-first particulate radiation and electromagnetic radiation. Particulate radiations are energetic particles which will travelin a straight line if unhindered. Three types of particulate radiation of interest in nuclear energy, those being beta particles which are high-energy electrons (not part of an atom), neutrons, and alpha particles which consist of two protons and two neutrons. Electromagnetic Radiations are high-energy waves (or photons) which have no apparent mass (not a particle). There are two types of electromagnetic radiation of interest which are gamma rays and X-rays. Gamma rays have their origin in the nucleus of the atom. X rays have their origin in the stored energy of the electrons orbiting the nucleus. There are many important differences in the behavior of these radiations which will be discussed in the later sections.
Radioactivity Radionuclides are atoms that are unstable and will eventually reach a stable state through a process know as radioactive decay. This process results in the emis.sion of energy or energetic particles from the nucleus of the unstable atom. The process may occur in a single step or may be composed of a scrics of steps to various radioisotopes. When this process proceeds through a series of steps it is called a radioactive decay series.
There are at least three natural radioactive decay series which are the thorium, neptunium, and the uranium series. These radioactive-decay series as well as naturally occurring K(potassium)-

contributors to background radiation levels, which are addressed in greater detail later.
The rate at which atoms undergo radioactive decay xF varies greatly. A common expression of the 31/2 tendency for radioactive decay is the half-life 4
associated with a particular isotope. The half-life is 1/4 the amount of time required for one-half of the

n RADIATION INTERACTION WITH MATTER v
Ionization As alpha, beta, gamma, and X-ray radiation interact with matter they impart part or all of their energy to the matter in a single interaction. It may require many interactions to absorb the energy of a single particle or photon of radiation. One of the most common ways energy is dissipated is ionization. As N
we discussed earlier this results in the creation of a positively g
gtge7acu charged atom and a free electron. The positively charged atom e
and the free electron are referred to as a charged pair. The creation of the charged pair is one of the primary contributions to damage of biological systems.
Radiation Ranges Figure 5: Ionization Each type of radiation we have discussed interacts with the matter they travel thr,n a differently because of the different characteristics of each radiation.
Alpha particles are composed of two protons and two neutrons. This is the heaviest particulate radiation with a positive charge of two (two protons). The alpha i
O paiticle is the slowest of the radiations we will review U
with a speed of no more than 20,(XX) miles per second.
fflll_..
" - d... :.z _.
As a result of these characteristics the alpha travels only
=
a few centimeters (or inches) in air and is readily stopped by a sheet of paper. The alpha leaves its energy in a short distance characterized by a great many ionizations.
Beta particles are basically a very high-energy electron.
Beta particles have a negative charge. It is a very light particic, with a mass of about one two-thousandth of a proton (or about one eight-thousandth of an alpha particle). Beta particles are very fast, approaching the speed of light. Due to their speed and lower charge, the beta particles travel several meters (or yards) in air and are readily stopped by a small piece of metal or other dense material. The beta particle leaves its energy in many ionizations but with the ionizations distributed along a much longer path of travel.
Gamma rays are photons (or energy waves, not a charged particle). Like light (also a photon) it travels at a speed of approximately 186,(XX) miles per second. The gamma ray travels much larger distances without interacting. When the gamma ray interacts with matter it creates very high-energy electrons similar to beta particles which in turn create ionizations as their energy is dissipated. Due to these differences the gamma ray travels much greater distances before its energy is dissipated. To dissipate the energy of a gamma ray severalinches oflead are required.

- p" RADIATION QUALITIES AND UNITS OF MEASURE There are numerous qualities and units used to describe radiation and radioactivity and their l
cffects. Those used in this report relate to activity, absorbed dose, and dose equivalent. It is also common to express numbers in scientific notation or use prefixes with the number denoting the number of zeros (0) before or after the decimal. A few examples are provided below.

lx1(f Activity is the number of radioactive transformations (decays, disintegrations) that occur in a fixed time interval. The unit used to express activity is the curie. The curie is defined as b
37,(XX),(X)0,(XX) disintegrations per second; (also expressed as 3.7x10"'s-'). A curie is a unit of activity, not an amount of material or the number of atoms. The amount of material or number of atoms necessary to produce a curie of activity vary over a very wide range. Atoms with very long half-lives would require many more atoms to produce a curie of activity versus atoms with short half-lives.
Absorbed dose describes the energy absorbed per unit of mass of tissue. The unit used to express absorbed dose is the rad (radiation absorbed dose). One rad is an absorbed radiation dose of 100 crgs (a measure of a very small amount of energy) ner gram. The rad can be used with all types of radiation including X-rays, gamma-rays, and paniculate radiations. The absorbed dose can be measured with various radiation-detection instruments which allows the assessment of damage to biological systems subjected to radiation and radioactive materials.
Dose equivalent is an expression of the biological effect of the radiation on tissue. The unit used to express absorbed dose equivalent is the rem. Dose equivalent is obtained by multiplying the absorbed dose (expressed in rad) by a quality factor (QF) for the type of radiation being considered.
Dose equivalent = absorbed dose X anality factor Some types of radiation create more biolegical damage due to the extent of ionization in small j
areas. From our discussion of alpha particles, the intense ionizations caused by the alpha particle i
results in a much higher Quality Factor for this radiation. This relationship for quality factors and different radiations we have discussed is illustrated below 7

Alpha Particles 20 SOURCES OF RADIATION Background Radiation Radiation occurs naturally and is an everyday fact of our existence. Mankind has always lived with radiation and radioactive materials and will continue to in the future. The radiation that occurs naturally is referred to as background radiation. Mankind experiences two types of radiation dose: first is radiation that originates outside the body and is called external radiation, (O
and the second is radiation that originates inside the body and is called internal radiation.
t External radiation comes from the carth, the atmosphere, and every structure (buildings) around us as well as a source referred to as cosmic radiation which is generated in the stars throughout the galaxy including our own sun.
Cosmic radiation is composed of gamma-rays (some of very high energy) and many different types of energetic particulate radiation. Some of the particulate forms of radiation include neutrons, alpha particles, and heavy particles (including nuclei). These high-energy cosmic radiations have the capability to interact with other atoms on earth and generate new isotopes. As we have already discussed, some of these may be radioactive. Common examples of radionuclides formed from cosmic radiations are carbon-14 and tritium (H-3). The atmosphere around the carth serves as an effective shield causing much of the energy of cosmic radiations to be dissipated prior to reaching the surface of the earth. However, each of us may receive a dose equivalent, due to external cosmic radiation, to 20 to 50 mrem (.020 to.050 rem) annually. The actual dose is influenced by the elevation at which we live. Higher elevations provide less shielding and therefore the doses are higher. A single plane flight can also contribute to our dose from cosmic radiations. The average passenger could expect to receive a dose of 2.8 mrem
(.0028 rem) per flight.
Another important contributor to external absorbed dose is terrestrial radiation. This is the O
8
radiation from the earth itself, and the air around each Source of Radiation Dose of us. The sources of terrestrial radiation include the thorium, neptunium, and the uranium decay series as 4,,,,
well as potassium-40. The absorbed dose varies about 15 to 140 mrem (.015 to 140 rem) annually.
However there are a very few areas that these terrestrial absorbed doses exceed 800 mrem each year.
One of the most important sources of dose is that contributed by internal radiations. These radionuclides are part of our body, the air we have breathed, or the food we have consumed. One if the most significant Radon E Terrestrial contributors is radon. Radon is a radioactive gas that cosmic internal is part of the uranium decay series. Radon's J.

concentration varies greatly based upon the geology of cach community, but is found in soils and rock every-Figure 7: Radiation Sources ( BIER V) where. Ifit is allowed to concentrate in a building, the j
dose from radon can be increased significantly. Normally radon does not pose a significant health 1
threat. Since radon is an alpha particle emitter, inhaling radon gas makes the lung our greatest concern (IE the alpha does not travel far but has a high quality factor for the affected tissue)/ The l
health effect of breathing radon is an increased risk oflung cancer.
Man made radiations are important to i O Man-made Rad. tion radiation. An important aspect in discussing completing our understanding of sources of ia man-made radiation is the benefit man derives from the use of these. Medical uses of y,
radiation are the major contributor, including

q HEALTH EFFECTS OF RADIATION D
The effects ofionizing radiation has been of concern to the scientific community for several decades. The oldest body established to study radiations biological effects date from at least 1928 with the establishment of the International Commission on Radiological Protection. Much of our knowledge is based upon very high doses from animal experiments, accidents handling radioactive materials, and war time nuclear weapons use and its survivors. It has been a classical problem of how to relate doses at these levels to much lower medical use ( although some treatments are designed to deliver high dose) and occupational radiation levels. Environmental levels of radiation represent even greater challenges because of the extremely low doses compared with medical and occupational levels. Experiments with animals represent additional challenges because they may not accurately represent human biological responses to radiation.
Radiations biological effects are classified as somatic and genetic ( or hereditary). Somatic effects are observed in the individual receiving the radiation dose. Genetic effects are observed in the decedents of the individual receiving the radiation dose.
Somatic effects can be classified as acute or chronic. Acute effects occur within a short time (days) after the dose is received. Generally acute effects require very high doses. Blood changes have been observed in the range of 25 to 50 rem ( or 50,(XX) mrem). Other acute effects can be expected at even higher doses. Our knowledge of this level of dose are the survivors of nuclear weapons, accidents, and planned medical treatments. These dose levels are more than 500 times normal environmental background radiation. For this reason, these effects are not important to a discussion of environmental radiation.
Chronic effects are generally used to refer to effects that are observed a long period of time and these have also been referred to as delayed effects. The effects are also generally associated with radiation dose received over a long period know as chronic exposure. However is not necessary for the exposure to occur over a long period. The most important chronic effect is cancer. There are numerous forms of cancer. The rate of cancer in individuals at low doses ( at occupational or environmental levels) has not been observed directly. " Cancers induced by radiation are indistinguishable from those occurring naturally; hence, their existence can be inferred only on the basis of statistical excess above the natural incidence." The current practice is to use observations at much higher dose to establish the rate of cancers at that dose and then assume that the rate of cancers must be proportional to the lower dose. This has created a scientific disagreement, because some scientists believe this method over estimates the cancer risk from low doses of radiation. However this appears to be a conservative assumption. Some risk exists but it is believed to be a small risk of cancer at occupational levels. The Committee of the Biological Effect of Ionizing Radiation further states "It is by no means clear whether dose rates of gamma or X-rays of about 100 mrad per year are in any way detrimental to exposed people....." Environmental radiation levels are in the range of 100 mrad per year or less as we have discussed.
Genetic radiation effect occur when radiation changes the genetic material in cells. As we have discussed the process of ionization removes electrons from the atom. These electrons are 10
a l
l sometimes necessary in the creation of chemical bonds. If the bonds are part of the genetic material of the cell, it could result in changed genetic material ( mutations). Radiation is just ore l
of several agents that contribute to genetic change. Chemicals including those that occur i
L naturally are a significant contributor to genetic mutations. Background radiation levels only provide a minor contribution to total mutations. To double the general mutation (from all sources) rate would require a dose of 50 to 250 rem ( or 50,000 to 250,000 mrem). This is approximately 500 to 2,500 times the normal environmental background of about 100 mrem.
i GENERAL HEALTH RISK i
Every human activity has risk associated with it. The air we breath, the food we cat, where we live or work all have different risks. Many times our perception of these risks is quite different L
. than the real risk of an activity. There was widespread fear and misunderstanding regarding the fire and safety hazard from electricity early this century. Now electricity is accepted as part of our daily existence. Radiation is unique in that it can not be seen, felt, smelled, or detected by any of the human senses. It is detected by instruments or laboratory analysis specially designed to detect radiation. Thus it is understandable to be wary of something we can not readily sense and may not have a personal knowledge about. There are other similar hazards we tend to accept such as micro-wave radiations, carbor. monoxide in the operation of some furnaces and our vehicles due to our familiarity witn these.
A common was of expressing risk is a reduction of life expectancy from a particular activity.

NUCLEAR POWER PLANT OPERATIONS The primary difference between a nuclear generating station and fossil generating station is the source of heat or thermal energy. The steam turbine, condenser, condensate and feed water systems are much the same. The uranium fuel within the nuclear reactor is the source of heat or energy in the nuclear generating station.
l Nuclear Fission l
l Certain heavy radionuclides are known to naturally undergo a special form of radioactive decay, called spontaneous fission. Spontaneous fission means the nuclei of these radioisotopes literally l
split into two or three new nuclei ( also known a fission fragments) and a few free neutrons (not in a nucleus). The protons and neutrons are shared between these new nuclei. One isotope of Uranium known a U-235 is known to undergo fission. The other more common isotope of Uranium known as U-238 does not fission so easily.
Fission can also be stimulated by neutrons interacting with the nucleus of these atoms. Simply stated a neutron reaches the nucleus and produces fission fragments, free neutrons, and heat.
l Fission of Uranium produces more than one neutron per fission. Therefore; if there is enough uranium (especially U-235) present is it possible to produce more fissions and keep the process i
going or cause more and more fissions to occur. When the rate of fission initiated is self l
sustaining or increasing a chain reaction has been established. It is this sustained chain reaction and the energy produced that produces the heat needed to generate steam for electrical generation.

i Uranium Fuel 4 o Uranium is mined from the carth the same as many minerals are as an ore. This uramum ore is then taken to a mill to concentrate the uranium. The extraction process for uranium uses acids to dissolve the uranium and separate it from the ore. This uranium is then converted chemically to a gas " anium hexafloride (in chemical notation UF ) While in this form it is possible to 6
separate the lighter U-235 from the heavier U-238. This process of separation is called gaseous diffusion. The reason for NUCLEAR FUEL CYCLE separation is to allow more of the U-A 235 to be included in the fuels used in h
commercial reactors. We have already J

suppression chamber partially filled with water. This suppression chamber functions to suppress the energy of the reactor in conditions in which the condenser is not available to receive the steam or energy from the reactor. The steam produced by the reactor is transferred to the suppression chamber through pressure relief valves and piping.
The secondary containment is the reactor building itself. This secondary containment is maintained at a pressure lower than the pressure outside the building. This is accomplished by a system of fans and filter systems that treat the air inside the secondary containment; thus, any air leakage would be into the secondary containment from the outside. The air coming from secondary containment is all filtered and treated prior to discharge.

g REACTOR SAFETY m
There are several points regarding nuclear safety that are important to understand and these are:
+
Commercial nuclear generating station can not explode as a nuclear weapon. The uranium for weapons is highly enriched and must be carefully timed and configured to create an explosion. The uranium in commercial generating stations is low enrichment and can not be contigured to create a nuclear explosion.
+
The reactor control system regulates the power output of the reactor by controlling the rate of nuclear fission. This is accomplished by inserting or withdrawing control rods or by the addition of neutron absorbing materials. A special safety system is part of the reactor control system call the reactor protection system which will cause the control rods to be quickly inserted. This insertion causes to nuclear chain reaction to stop. There are numerous sensors that measure different plant conditions that would cause the reactor protection system to activate.
+
There are several emergency systems that provide adequate cooling and water to the reactor in the event these are required. Should there be breakage of piping carrying water to the reactor this is referred to as a Loss of Coolant. These systems are activated upon a drop in reactor pressure or a low level of water in the reactor. The exact activation vary by reactor type. These systems that delivery this supplemental source of water are referred to a the Emergency Core Cooling System. There are even backup systems to N
the individual Emergency Core Cooling Systems. This practice is referred to a defense in depth. Safety is not dependent on any one device but is a system of several backups.
The Brunswick Nuclear Plant is designed to be a safe means of generating electrical power. This level of safety is further enhanced through the discipline of operation provided by a well qualified and trained staff. Ongoing training is provided to the staff to ensure a high quality performance from each member of the plant staff. Although the requirements are high for the staff, reactor operators and senior reactor operators must also pass a rigorous license examination by the Nuclear Regulatory Commission on a regular basis. These examinations test knowledge of plant systems, design, procedures, problem solving, regulatory requirements, and the ability to function as a team responding to plant conditions.

' o RADIOLOGICAL ENVIRONMENTAL U
MONITORING PROGRAM PURPOSE AND REQUIREMENTS FOR THE RADIOLOGICAL MONITORING PROGRAM Although the operation of a nuclear generating station results in the raising of background ladiation only a small amount, it is important to measure these emissions of radioactivity and radiation to access their impact on the surrounding populations. The purpose of the radiological monitoring program is to measure accumulation of radioactivity in the environments, to determine whether this radioactivity is the result of operations of the Brunswick Plant, and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin. Radiological monitoring programs provide an additional verification of the containment and radiological controls of nuclear generating stations.
The radiological monitoring program was established in 1973 and continued to collect samples and evaluate them for twenty four (24) years.
Requirements are established for the radiological monitoring program as follows:

The Cape Fear River is cast of the plant and cooling water is drawn from the river through a canal. The cooling water is discharged to the Atlantic Ocean through a canal, pumping station, and piping. The discharge point is south of the town of Caswell Beach.
The plant site varies in elevation from sea level to thiny (30) feet above mean sea level (M.S.L.).
It is surrounded by extensive marshes. The lower Cape Fear River is an important nursery area for shell fish, and other marine species.
The local economy supports significant recreational, industrial, agricultural, and government contributions. There is well developed recreational use of the barrier islands south and east of the site. Fishing and boating are popular activities. Commercial fishing is also an important industry in the community. Agricuhure utilizes less than half ofland within 50 miles of the site.
Agricuhural activities are small truck farms, cattle, poultry, and row crops including corn, soybeans and tobacco. Industrial activity includes the Archer-Daniels-Midland Chemical Company, a manufacturer of citric acid located one and a half (1.5) miles southeast of the plant.
In conjunction with the citric acid plant is a small electrical generating station operated by Cogentrix, Inc. This coal fired station is composed of two units rated at 55 MWe each.
Transportation is a significant industry in the local economy with the Port of Wilmington north of the site. The ships channelis just east of the site in the Cape Fear River. Also the Sunny Point i
Military Ocean Terminal is located approximately four and one half (4.5) miles north of the plant i
site and on the Cape Fear River.

' o RADIOLOGICAL MONITORING PROGRAM V
l QUALITY ASSURANCE A required component of the environmental radiological monitoring program is the Quality Assurance Program. The standards for the quality assurance program are established in the NRC Regulatory Guide 4.15," Quality Assurance for Radiological Monitoring Programs." The purpose of the quality assurance program is "(1) to identify deficiencies in the sampling and measurement processes to those responsible for these operations so that corrective action can be taken, and (2) to obtain some measure of confidence in the results of the monitoring programs in order to assure the regulatory agencies and the public that the results are valid." NRC Regulatory Guide 4.15, Pg. 4.15-2. This provides the opportunity to implement corrective actions that address possible deficiencies. Examples of the activities of the quality assurance program include:
regular review of sample collection and records regular review oflaboratory procedures and methods participation in the Analytics, Inc., Environmental Cross-Check Program, which provides e
an independent assessment of the quality oflaboratory results.
the use of known concentrations of radioactivity in test samples by the laboratory to ensure consistent quality results on an ongoing basis.

l llp RADIOLOGICAL MONITORING PROGRAM V
GENERAL DESCRIPTION Although the contribution to background radiation is small, we have established this program to measure the exposure pathways to man. An exposure pathway describes the source of the radiological exposure. The primary forms of radiological emissions from the plant are airborne and liquid discharge. The following pathways are monitored external dose, ingestion of radioactive materials, and the inhalation of radioactive material. Specific methods and different environmental media are required to assess cach pathway. Below in Table 3 is a list of the media used to assess each of these pathways.

Shoreline Sediment Ingestion Broadleaf Vegetation Fish and Invertebrates AV Surface Water Inhalation Air Samples (Particulate & Radioiodine)
Sampling Locations Sampling locations are chosen based upon meteorological factors, preoperation monitoring, and results of the land use surveys. A number oflocations are selected as controls. Control stations j
are selected because they are very unlikely to be affected by operation of the plant. Sample i
locations may be seen in figures 16 and 17. A description of each sample location may be found in Table 4.

SUMMARY
OF RADIOLOGICAL MONITORING PROGRAM
( )/
This report presents the results of the Radiological Environmental Monitoring Piogram conducted during 1996 for the Brunswick Nuclear Plant (BNP). The program was conductec,in accordance with Technical Specification 4.12.1, the Off-site Dose Calculation Manual. and aoplicable procedures.
The 1996 Annual Radiological Environmental Operating Report (REOR) has been prepared in accordance with Technical Specification 6.9.1.7 and is being submitted in accordance with Technical Specification 6.9.1.6. The report applies to both BNP Units 1 and 2 (License Nos. DPR-071 and DPR-062, respectively).
Nearly 1,025 samples from six environmental media types were analyzed during the year. No detectable radioactivity (or radioactivity which did not differ significantly from the corresponding control) was observed in any of the 850 measurements taken at indicator locations. All samples analyzed met the LLD requirements as established by Technical Specification 6.9.1.7.h and Table 4.12.1-1.
D (O
A statistical summary of all the data gathered in 1996 has been compiled in Table 5.
The radiological environmental data indicates that BNP operations in 1996 had no significant impact on the environment or public health and safety. No measurable radiation exporare is attributed to any off-site member of the public due to the operations of BNP.
1 l
Comparison of the current data with preoperational (1973,1974) information (Tables 6 and 7) indicate that air particulate filter gross beta activity and ambient gamma radiation levels were lower in 1996.

i INTERPRETATIONS AND CONCLUSIONS i
I i
Air Monitorine l
l
. The average gross beta concentration measured in 265 air particulate samples collected at indicator stations during 1996 was 1.72 E-2 picoeuries per cubic meter (pCi/m'). The preoperational (1973-t 1974) average concentration was 8.2 E-2 pCi/m', while the average activity in the recent past (1992-1995) was 1.73 E-2 pCi/m'(Table 6). The airbome concentrations of gross beta activity in 1996 are indicative of natural background and do not indicate any abnormal activities originating from the I
nuclear olerations at the Brunswick Nuclear Plant (BNP). Figures 18 through 22 depict the monthly variations of these values.
Gamma analyses of the composited air particulate filters indicated that all of the radionuclides indicative of plant effluents were at concentrations less than their respective LLDs. All radionuclides positively identified by the radionuclide analyses were typical of naturally occurring materials.
Analyses of 265 indicator location air cartridges for the collection of radiciodines indicated that concentrations of those radionuclides, and particularly I-131, were less than the LLD.
O No milk sampling locations are currently identified in the BNP environs, and therefore no sampling of this media was available.
Veeetation l
Food crops were not grown in the vicinity of the plant in 1996 and this media was represented by l
mdigenous vegetation samples consisting primarily of wild cherry, wax myrtle, and sweetgum leaves along with fescue grass. Ninety-three samples were collected from indicator locations and 31 from the control location. No detectable activities relating to plant effluents were detected in this sampling media.
Fish and Invertebrates i
Fish and invertebrate samples are collected semiannually from two locations: (1) near the Atlantic Ocean discharge pipe at Caswell Beach and (2) a control location in the Atlantic Ocean not
}
influenced by plant operations. In all 12 samples, the radionuclide content was determined to be less than the respective LLDs for the gamma-emitting radionuclides.
30
Shoreline Sediments A
Two shoreline sediments are drawn from the beach area near the pumping station location at Caswell Beach. No detectable activities relating to plant effluents were detected in this sampling media.
Surface Water i
Surface water is sampled monthly from the intake and discharge canal. These samples are analyzed for gamma-emitting radionuclides and for tritium. Neither of these analyses indicated any detectable concentrations of radionuclides in the 12 indicator samples. Figure 23 depicts the observed tritium concentrations for 1996.
External Radiation Exposure The environmental data on external radiation exposure for 1996 was essentially unchanged from 1989-1995 with an average exposure for all indicator locations of 0.78 mR per week or 10.1 mR per quarter. The average exposure observed over the preoperational period was 1.02 mR per week observed from the fourth quarter of 1972 through the second quarter of 1975. Table 7 provides a j
comparison of recent data with the preoperational and historical data.
l The highest average exposure occurred at Fort Caswell Baptist Assembly 4.5 miles S. That dose was 12.0 mR per quarter. Figure 24 depicts average inner and outer ring TLD data for each quarter of 1996. This depiction does not indicate a signific ant higher exposure rate for the inner versus the outer ring. This is interpreted as demonstrating that no discernible off-site exposure arises from plant operations.

- TLD 72 was missing in the field.
Second Quarter
- TLD 72 was missing in the field.
Third Quarter
- TLDs 72 and 76 were missing in the field Fourth Quarter
- TLD 76 was missing in the field.
ANALYTICAL PROCEDURES Gross Beta Gross beta radioactivity measurements are made utilizing a Tennelec Low-Background Alpha / Beta Counting System. The LLD for air particulates is approximately 3.0 E-3 pCi/m'.
i Air particulate samples are mounted in 2-inch stainless steel planchets and counted directly for i
50 minutes.
Tritium Liquid samples requiring tritium analysis are treated with a small amount of sodium hydroxide and potassium permanganate crystals and then distilled. Five milliliters of the distillate are mixed with thirteen milliliters of liquid scintillation cocktail and counted in a liquid scintillation counter for 50 minutes. The LLD for this count time was approximately 1000 pCi/L through May 1996.
During June 1996, the sample count time was increased to 500 minutes with a LLD of approximately 325 pCi/L. This increase was established to compare our tritium LLDs and results with State Agency's reportable concentrations, in the Split Sample Program's Annual Report, as per plants' request.
Iodine-131 Iodine-131 airborne concentrations are analyzed by the intrinsic germanium (Ge) gamma spectrometry systems. The cartridges are placed on the detector and each charcoal cartridge is counted individually with an approximate LLD of 3.0E-2 pCi/m'.
j Gamma Spectrometry
/
Gamma spectrum analysis utilizes intrinsic germanium detectors with thin aluminum windows l-housed in steel and lead shields. The analyzer system is the Canberra Nuclear 9900 Gamma 34
l',m Spectroscopy System. Table 8 summarizes LLD values derived from instrument sensitivity based
(]
upon a blank sample background.
Air particulate filter quarterly composites are placed in a Petri dish and analyzed directly for 3,600 seconds.
Liquid samples are boiled down to reduce the volume, transferred to 1000-ml Marinelli beaker, and analyzed for 10,000 seconds.
Shoreline sediments are dried, ground, weighed, and then analyzed in a Marinelli beaker for 1,500 seconds.
Broadleaf vegetation is weighed wet and analyzed in a Marinelli beaker for 7,500 seconds.
Fish samples and edible portions of intervebrate organisms are cleaned, dressed, and placed in a Marinelli beaker for analysis for 1,500 seconds.
Thermoluminescent Dosimetry Each area monitoring station includes a TLD packet, which is a polyethylene bag containing three calcium sulfate phosphors contained in a Panasonic UD-814 badge. The TLD is lighttight and the fs(j bag is weather-resistant.
Dosimeters are machine annealed before field placement. Following exposure in the field, each dosimeter is read utilizing a Panasonic TLD reader. This instrument integrates the light photons emitted from traps as the dosimeter is heated above 150 C. The photons from the lower-energy traps are automatically eliminated through a preheat cycle. Calibration is checked regularly using dosimeters irradiated to known doses. Prior to the measurement of each dosimeter, the instrument is checked through use of an internal constant light source as a secondary standard.
The exposure reported is corrected for exposure received in transit and during storage through the use of control dosimeters.
Interlaboratory Comparison Program The Radiochemistry Laboratory at the llarris Energy & Environmental Center in New Hill, North Carolina, provides radioanalytical services for CP&L's nuclear plant radiological environmental monitoring programs. In fulfillment of Technical Specification 3/4.12.3, the laboratory is a i
participant in the Analytics, Inc.'s Environmental Cross-check Program and uses its performance in this program as a major determinant of the accuracy and precision of its analytical results. The lp change in vendors for the Interlaborator) Program was due to the EPA Environmental Cross-check l
Program's termination as of December 31,1995.
t 35
l i
During 1996,81 analyses were completed on 16 samples representing five major environmental
-l media (water, milk, and air filters, soil, and air cartridges). Data on the known activities and the standard deviations for the 81 analyses have been received from Analytics,Inc.. A comparison l
of the average of our reported values with Analytics, Inc. known activity and standard deviation is provided below:
1 1
Standard Deviation From Known Activity Percent of Analyses s 1 standard deviation 61 s 2 standard deviation 85 i
s 3 standard deviation 94
)
Five of 81 analyses exceeded the 3 sigma action level. This was a gross alpha / beta in water from First Quarter 19% Gross Alpha / Beta in Water (E0658-72) and three gammas from Second Quarter 19% Gamma in Water (E0734-72) and an Air Filter gamma (E0737-72).
The gross alpha / beta results were investigated by the following means: (1) rechecked counts and efficiency used, (2) instrument efficiency was verified and checked against 1995's efficiency, (3) samples had been disposed of so a recount was unobtainable, (4) reanalyzed an aliquot of remaining original sample, and (5) spiked the sample - recovery was also high; therefore, the investigation did not determine a reason for the erroneous result. The laboratory also participates in a Radiochemistry Effluent Interlaboratory Comparison Program (vendor - Analytics, Inc.)
which checks our performance (accuracy and precision) on Gross Alpha / Beta, Sr-89/90, and Fe-
- 55. The Gross Alpha / Beta results for 1996 were within Analytics, Inc.'s acceptable criteria range.
The three gamma results that exceeded the three sigma value in the Second Quarter were within -
acceptable range in the Third Quarter 1996 Cross-Check sample.
Lower Limits of Detection All samples analyzed met the LLD required by Technical Specification 6.9.1.7 and Table 4.12.1-
- 1. Typical "a priori" LLD values for the samples analyzed are listed in Table 8.

q LAND-USE CENSUS C/
PURPOSE OF THE LAND-USE CENSUS The land-use census identifies the pathways (or routes) that radioactive material may reach the general populations near commercial nuclear generating stations. This is accomplished by completing studies each year that identify how the surrounding lands are used by the population.
A comprehensive census of the use of the land within a five mile distance of the plant is completed during the growing season each year. This information is used for dose assessment and to identify changes to the stations sampled and the type of samples. These results ensure that the Radiological Environmental Monitoring Program (REMP) is based upon current data regarding human activity in the vicinity of the plant. Therefore the purpose of the land-use census is both to ensure the monitoring program is current as well as provide data for the calculation of estimated radiation exposure.
The pathways that are evaluated are:
+
Ingestion Pathway - Results from cating food crops that may have radioactive materials deposited on them, incorporated radioactive materials from the soil or atmosphere. Another pathway is through drinking milk from local cows or goats if these are present. The grass (w) used to feed these animals may have incorporated or had deposited on it radioactive i
\\
materials that can be transferred to the milk.
+
Direct Radiation Exposure Pathway-Results from deposition of radioactive materials on the ground or from passage of these radioactive materials in the air.
+
Inhalation Pathway-Results from breathing radioactive materials transported in the air.
Methodology 1
The following must be identified within the five (5) mile radius of the plant for each of the j
sixteen meteorological sectors (compass direction the winds may blow, for example NNE [ North North East]):
+
The nearest resident
+
The nearest garden of greater that 500 square feet, producing broadleaf vegetables
+
The nearest milk animal The primary method is visual inspection from roadside within the five (5) mile radius, with the l
exception of the Military Ocean Terminal. This information is supplemented with data from aerial photographs, information from county extension agents, and farm supply businesses.
,O v
39
i 1996 Land-Use Census Results The 1996 and 1995 results of the survey for the nearest resident, garden, milk and meat animals l
in each sector are compared in Table 9.
There was no change in the location of the nearest resident in each sector. The following changes in the status of the gardens occurred with the addition of gardens in the NNE sector at I
1.2 miles and in the ESE sector at 1.6 miles. There is no longer a garden at 0.8 miles in the NNW sector, but one was located at 4.4 miles in this sector. Neither milk nor meat animals are located within 5 miles of the plant.
