SUMMARY

I This Annual Monitoring Report for the period of January 1, 2001, through December 31, 2001, is submitted in accordance with Point Beach Nuclear Plant (PBNP) Units 1 and 2 Technical Specification 5.6.2 and filed under Dockets 50-266 and 50-301 for Facility Operating Licenses DPR-24 and DPR-27, respectively.

The report presents the results of effluent and environmental monitoring programs, solid waste shipments, non-radioactive chemical releases, and circulating water system operation.

During 2001, the following amounts of radioactive material were released via the liquid and atmospheric pathways:

Liquid Atmospheric Tritium (Ci) 588 79.6 Particulate (Ci) 0.14 0.002 Noble Gas (Ci) -3.0 (-) Noble gases in the liquids are added to the atmospheric release totals. For the purpose of regulatory compliance with the effluent design objectives of Appendix I to 10 CFR 50, doses from effluents are calculated for the hypothetical maximally exposed individual (MEI) for each age group and compared to the Appendix I objectives.

Doses less than or equal to the Appendix I values are considered to be evidence that PBNP releases are as low as reasonably achievable (ALARA). The maximum annual calculated doses are shown below and compared to the corresponding design objectives of 10 CFR 50, Appendix I. LIQUID RELEASES Dose Category Calculated Dose Appendix I Dose Whole body dose 0.006 millirem 6 millirem Organ dose 0.009 millirem 20 millirem ATMOSPHERIC RELEASES Dose Category Calculated Dose Appendix I Dose Organ dose 0.03 millirem 30 millirem Noble gas dose to the skin 0.0006 millirem 30 millirem Noble gas dose to the whole body 0.0004 millirem 10 millirem Noble gas beta air dose 0.0002 millirad 40 millirad Noble gas gamma ray air dose 0.0004 millirad 20 millirad The results show that during 2001, the doses from PBNP effluents were a small percentage

(- 0.1% at the most) of the Appendix I design objectives and therefore operation of PBNP continues to be ALARA.1 In addition to collecting and analyzing environmental samples, a survey of land use with respect to the location of dairy cattle was made pursuant to Section 2.5 of the Environmental Manual. As in previous years, no dairy cattle were found to be grazing at the site boundary.

Therefore, the assumption that cattle graze at the site boundary used in the evaluation of doses from PBNP effluents remains conservative.

The 2001 Radiological Environmental Monitoring Program (REMP) collected 464 samples for radiological analyses and 144 sets of thermoluminescent dosimeters (TLDs) to measure ambient radiation in the vicinity of PBNP and the Independent Spent Fuel Storage Installation (ISFSI).

Air monitoring from six different sites showed only background radioactivity from naturally occurring radionuclides.

Terrestrial monitoring consisting of soil, vegetation, and milk found no influence from PBNP. Similarly, samples from the aquatic environment, lake and well water, fish, and algae, revealed no buildup of PBNP radionuclides released in liquid effluents.

The data analysis shows no plant effect on its environs.

As of December 2001, the ISFSI contained a total of 13 ventilated storage casks (VSC-24).

During 2001, one cask was transferred to the ISFSI. The subset of the PBNP REMP samples used to evaluate the environmental impact of the PBNP ISFSI showed no environmental impact from its operation.

The environmental monitoring conducted during 2001 confirms that the effluent control program at PBNP ensures that its operations minimally impacts the environs.2

1.0 INTRODUCTION

The PBNP effluent monitoring program is designed to comply with federal regulations for ensuring the safe operation of PBNP with respect to releases of radioactive material to the environment and its subsequent impact on the public. 10 CFR 50.34a states that operations should be conducted to keep the levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA). In 10 CFR 50, Appendix I, the Nuclear Regulatory Commission (NRC) provides the numerical values for what it considers to be the appropriate ALARA design objectives to which the licensee's calculated effluent doses may be compared.

These doses are a small fraction of the dose limits specified by 10 CFR 20.1301 and lower than the Environmental Protection Agency (EPA) limits specified in 40 CFR 190. 10 CFR 20.1302 directs PBNP to make the appropriate surveys of radioactive materials in effluents released to unrestricted and controlled areas. Liquid wastes are monitored by inline radiation monitors as well as by isotopic analyses of samples of the waste stream prior to discharge from PBNP. Airborne releases of radioactive wastes are monitored in a similar manner. Furthermore, for both liquid and atmospheric releases, the appropriate portions of the radwaste treatment systems are used as required to keep releases ALARA. Prior to release, results of isotopic analyses are used to adjust the release rate of discrete volumes of liquid and atmospheric wastes (from liquid waste holdup tanks and from gas decay tanks) such that the concentrations of radioactive material in the air and water beyond PBNP are below the PBNP Technical Specification concentration limits for liquid effluents and release rate limits for gaseous effluents.

Solid wastes are shipped offsite for disposal at NRC licensed facilities.

The amount of radioactivity in the solid waste is determined prior to shipment in order to determine the proper shipping configuration as regulated by the Department of Transportation and the NRC. Also operated at PBNP under the General License granted pursuant to 10 CFR 72.210 is an Independent Spent Fuel Storage Installation (ISFSI). The release of radioactive materials from the operation of the ISFSI must also comply with the limits of part 20 and the part 50 Appendix I design objectives.

Per 10 CFR 72.44(d)(3), the results of radiological effluent monitoring are to be reported annually.*

The dose criteria for effluents and direct radiation specified by 10 CFR 72.104 states that during normal operations and anticipated occurrences, the annual dose equivalent to any real individual Holders of a Part 72 license are allowed to submit the report required by 72.44(d)(3) concurrent with the effluent report required by 10 CFR 50.36a (a)(2). (

Reference:

64 FR 33178)3 beyond the controlled area must not exceed 25 mrem to the whole body, 75 mrem to the thyroid, and 25 mrem to any other organ. The dose from naturally occurring radon and its decay products are exempt. Because the loading of the storage casks occurs within the primary auxiliary building of PBNP, the doses from effluents due to the loading process will be assessed and quantified as part of the PBNP Radiological Effluent Control Program.

2.0 RADIOACTIVE

LIQUID RELEASES The release path to the environment contributing to radioactive liquid releases is circulating water discharge.

A liquid waste treatment system in conjunction with administrative controls are used to minimize the impact on the environment and maintain doses to the public ALARA from the liquid releases.

2.1 Doses

From Liquid Effluent Doses from liquid effluent are calculated using the methodology of the Offsite Dose Calculation Manual (ODCM). These calculated doses use factors such as the amount of radioactive material released, the total volume of liquid, the total volume of dilution water, and usage factors (e.g., water and fish consumption, shoreline and swimming factors).

These calculations produce a conservative estimation of the dose. For compliance with 10 CFR 50, Appendix I design objectives, the annual dose is calculated to the hypothetical maximally exposed individual (MEI). The ME1 is assumed to reside at the site boundary in the highest X/Q sector and is maximized with respect to occupancy, food consumption, and other uses of this area. As such, the MEI represents an individual with reasonable deviations from the average for the general population in the vicinity of PBNP. A comparison of the calculated doses to the 10 CFR 50, Appendix I design objectives is presented in Table 2-1. The conservatively calculated dose to the MEI is a very small fraction of the Appendix I design objective.

This sewage sludge, which may contain trace amounts of radionuclides, are to be applied in accordance with methodologies approved by the NRC on January 13, 1988, pursuant to 10 CFR 20.302(a).

The approved methodology requires analyses prior to every disposal.

Based upon an investigation of the source of the radionuclides, a combination of engineering modifications and administrative controls have eliminated plant generated radiological inputs to the sewage. This was verified by sludge analyses using the environmental lower level of detection (LLD) criteria, which found no byproduct radionuclides in the sludge after the controls and modifications were completed.

Sludge is routinely monitored and no radionuclides attributable to PBNP have been found. There was no disposal of sewage by land application during 2001. All disposals were done at Green Bay Metropolitan Sewage Treatment Plant.8

3.0 RADIOACTIVE

AIRBORNE RELEASES The release paths to the environment contributing to radioactive airborne release totals during this reporting period were the Auxiliary Building Vent Stack, Drumming Area Vent Stack, Unit 1 Containment Purge Stack, and Unit 2 Containment Purge Stack. A gaseous radioactive effluent treatment system in conjunction with administrative controls are used to minimize the impact on the environment from the airborne releases and maintain doses to the public ALARA. 3.1 Doses From Airborne Effluent Doses from airborne effluent are calculated for the maximum exposed individual (MEI) following the methodology contained in the PBNP ODCM. These calculated doses use factors such as the amount of radioactive material released, the concentration at and beyond the site boundary, the average site weather conditions, the locations of the exposure pathways (e.g., cow milk, vegetable gardens and residences), and usage factors (e.g., breathing rates, food consumption).

In addition to the MEI doses, the energy deposited by beta particles and gamma rays in air is calculated and compared to the corresponding Appendix I design objectives.

A comparison of the annual Appendix I design objectives for atmospheric effluents to the highest organ dose and the noble gas doses calculated using ODCM methodology is listed in Table 3-1. The doses demonstrate that releases from PBNP to the atmosphere continue to be ALARA. 3.2 Radioactive Airborne Release Summary Radioactivity released in airborne effluents for 2001 are summarized in Table 3-2. 3.3 Isotopic Airborne Releases The monthly isotopic airborne releases for 2001, from which the airborne doses were calculated, are presented in Table 3-3.9 Table 3-1 Comparison of 2001 Airborne Effluent Calculated Doses to 10 CFR 50 Appendix I Design Objectives Category Annual Appendix I Design Objective January-December Calculated Dose Percent of Appendix I Design Objective Particulate 30 mrem/organ 0.03 mrem 0.1 % Noble Gas 40 mrad (beta air) 0.0002 mrad 0.0005 % Noble Gas 20 mrad (gamma air) 0.0004 mrad 0.002 % Noble Gas 30 mrem (skin) 0.0006 mrem 0.002 % Noble Gas 10 mrem (whole body) 0.0004 mrem 0.004 %0 Table 3-2 Radioactive Airborne Effluent Release Summary January 1, 2001, through December 31, 2001 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Total Total Noble Gases' (Ci) 1.77E-01 1.41E-01 1.49E-01 2.85E-01 9.36E-02 1.14E-01 9.64E-02 7.91E-02 5.32E-02 1.25E-01 9.16E-02 6.42E-02 1.47E+00 Total Radioiodines (Ci) 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 2.67E-10 0.OOE+00 0.OOE+00 1.15E-09 0.OOE+00 0.OOE+00 1.41E-09 Total Particulates 2 (Ci) 5.66E-11 9.49E-04 0.OOE+00 0.OOE+00 0.OOE+00 5.08E-14 2.85E-09 6.22E-04 1.03E-06 7.58E-08 2.50E-09 0.OOE+00 1.57E-03 Alpha (Ci) 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 Strontium (Ci) 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 0.OOE+00 Gamma Emitters (Ci) 5.66E-11 9.49E-04 0.OOE+00 0.OOE+00 0.OOE+00 5.08E-14 2.85E-09 6.22E-04 1.03E-06 7.58E-08 2.50E-09 0.00E+00 1.57E-03 Total Tritium (Ci) 7.82E+00 5.34E+00 6.09E+00 1.04E+01 5.11 E+00 3.77E+00 4.03E+00 4.16E+00 1.14E+01 1.41E+01 3.91E+00 3.55E+00 7.96E+0I Max Hourly Release (Ci/sec) 1.83E-07 1.08E-07 9.56E-08 9.80E-08 7.80E-07 2.20E-07 1.38E-07 2.14E-07 9.32E-08 1.45E-07 9.83E-08 9.59E-08 (-) 1 Includes noble gas contribution form liquid releases.

R O IPart C RADIOLOGICAL ENVIRONMENTAL MONITORING

8.0 INTRODUCTION

The objective of the PBNP Radiological Environmental Monitoring Program (REMP) is to measure ambient radiation levels and to collect air, water, vegetation, fish, and soil samples and analyze them for radionuclide content in order to determine whether the operation of PBNP or the ISFSI has radiologically impacted the surrounding environment.

These measurements also serve as a check of the efficacy of PBNP effluent controls.

The REMP fulfills the requirements of 10 CFR 20.1302, PBNP General Design Criterion (GDC) 17, GDC 64 of Appendix A to 10 CFR 50, and Sections IV.B.2 and IV.B.3 of Appendix I to 10 CFR 50 for the operation of the plant. Therefore, the REMP collects samples from various environmental media in order to provide data on measurable levels of radiation and radioactive materials in the principal pathways of environmental exposure.

A subset of the PBNP REMP samples, consisting of air, soil, and vegetation, also fulfills 10 CFR 72.44(d)(2) for operation of the ISFSI. Additionally, thermoluminescent dosimeters (TLDs) provide the means to measure changes in the ambient environmental radiation levels at sites near the ISFSI and at the PBNP site boundary to ensure that radiation levels from the ISFSI are maintained within the dose limits of 10 CFR 72.104. Because the ISFSI is within the PBNP site boundary, radiation doses from PBNP and the ISFSI, combined, must be used to assess compliance with 10 CFR 72.122 and 40 CFR 190. Therefore, radiological environmental monitoring for the ISFSI is provided by selected sampling sites, which are part of the PBNP REMP. For the aquatic environment, the samples include water as well as the biological integrators, such as fish and filamentous algae. Because of their migratory behavior, fish are wide area integrators.

In contrast, the filamentous algae periphyton are attached to shoreline rocks and concentrate nuclides from the water flowing by their point of attachment.

Grab samples of lake water provide a snapshot of radionuclide concentrations at the time the sample is taken, where as analysis of fish and filamentous algae yield concentrations over time. The air-grass-cow-milk exposure pathway unites the terrestrial and atmospheric environments.

This pathway is important because of the many dairy farms around PBNP. Therefore, the REMP includes samples of air, general grasses, and milk from the PBNP environs.

An annual land use survey is made to determine whether the assumptions on the location of dairy cattle remain conservative with respect to dose calculations for PBNP effluents.

The dose calculations assume that the dairy cattle are located at the 20 south site boundary, the highest depositional sector. In addition, soil samples are collected and analyzed in order to monitor the potential for long-term buildup of radionuclides in the vicinity of PBNP. For the measurement of ambient environmental radiation levels that may be affected by direct radiation from PBNP or by noble gas effluents, the REMP employs a series of TLDs situated around PBNP and the ISFSI. 9.0 PROGRAM DESCRIPTION

9.1 Results

Reporting Convention The PBNP REMP results in this report are reported directly as measured by a detector which can meet the required lower level of detection (LLD) as specified in Table 2-2 of the Environmental Manual. If all of the measured values with their respective uncertainties are not statistically different from zero, the result is reported as "Not Detectable" (ND), indicating no detectable level of activity present in the sample. If one or more result is statistically greater than zero, all the generated data is used to determine the statistical parameters.

The lower limit of detection (LLD) is an a priori concentration value that specifies the performance capability of the counting system used in the analyses of the REMP samples. The parameters for the a priori LLD are chosen such that only a five percent chance exists of falsely concluding a specific radionuclide is present when it is not present at the specified LLD. Based on detector efficiency and average background activity, the time needed to count the sample in order to achieve the desired LLD depends upon the sample size. Hence, the desired LLD may be achieved by adjusting various parameters.

When a suite of radionuclides are required to be quantified in an environmental sample such as lake water, the count time used is that required to achieve the LLD for the radionuclide with the longest counting time. Therefore, in fulfilling the requirement for the most difficult to achieve radionuclide LLD, the probability of detecting the other radionuclides is increased because the counting time used is longer than that required to achieve the remaining radionuclide LLDs. When the radionuclide of interest is not present in the sample, the statistical nature of radioactive decay will produce negative and positive results centered about zero. Excluding validly measured concentrations, whether negative or as small positive values below the LLD, artificially inflates the calculated average value. Therefore, all generated data are used to calculate, when applicable, the statistical parameters (i.e., average, standard deviation) presented in this report. In interpreting the data, effects due to the plant must be distinguished from those due to other sources. A key interpretive aid in assessment of these effects is the 21 design of the PBNP REMP, which is based upon the indicator-control concept.

Most types of samples are collected at both indicator locations (e.g., nearby, downwind, or down stream) and at control locations (e.g., distant, upwind, or upstream).

A plant effect would be indicated if the radiation level at an indicator locations was significantly larger than that at the control location.

The difference would have to be greater than could be accounted for by typical fluctuation in radiation levels arising from other sources.

9.2 Sampling

Parameters Samples are collected and analyzed at the frequency indicated in Table 9-1 from the locations described in Table 9-2 and shown in Figures 9-1, 9-2, and 9-3. (The latter two figures show sampling locations not shown in preceding figures due to space limitations.

The PBNP REMP sampling site used to determine environmental impact around the ISFSI are found in Table 9-3. The minimum acceptable sample size is found in Table 9-4. In addition, Table 9-1 indicates the collection and analysis frequency of the ISFSI fence TLDs. 9.3 Deviations from Required Collection Frequency Deviations from the collection frequency given in Table 9-1 are allowed because of hazardous conditions, automatic sampler malfunction, seasonal unavailability, and other legitimate reasons (Section 2.2.6 of the Environmental Manual). Table 9-5 list deviations from the scheduled sampling and frequency which occurred during the reporting period. 9.4 Assistance to the State of Wisconsin The Radiation Protection Unit of the Wisconsin Department of Health and Family Services maintains a radiological environmental monitoring program in order to confirm the results from the Kewaunee Nuclear Power Plant and PBNP REMPs. As a courtesy and a convenience to the State of Wisconsin, PBNP personnel also collect certain environmental samples (Table 9-6) for the State from sites which are near PBNP sampling sites or are co-located.

The results of the State monitoring program are available from the Radiation Protection Unit of the Wisconsin Department of Health and Family Services.22

9.6 Analytical

Parameters The types of analyses and their frequencies are given in Table 9-1. The LLDs for the various analyses are found in the Section 10 (Table 10-1) with the summary of the REMP results. All environmental LLDs listed in Table 2-2 of the Environmental Manual (also in Table 10-1) were achieved during 2001. 9.7 Brief Description of Analytical Parameters in Table 9-1 9.7.1 Gamma isotopic analysis Gamma isotopic analysis consists of a computerized scan of the gamma ray spectrum from 80 keV to 2048 keV. Specifically included in the scan are Mn-54, Fe-59, Co-58, Co-60, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. However, any other nuclear power plant produced radionuclides, which are detected, also are noted. Naturally occurring radionuclides such as Ra-226, Bi-214, Pb-212, T1-208, Ac-228, Be-7, and K-40 are frequently detected in soil, sediment, and vegetation but are not normally reported.

All radionuclides detected by gamma isotopic analysis are decay corrected to the time of collection.

9.7.2 Gross

Beta Analysis Gross beta analysis is a non-specific analysis that consists of measuring the total beta activity of the sample. No individual radionuclides are identifiable by this method. Gross beta analysis is a quick method of surveying samples for the presence of elevated activity that may require additional, immediate analyses.

9.7.3 Water

Samples Water samples include both Lake Michigan and well water. The Lake Michigan samples are collected along the shoreline at four locations north and south of PBNP. The well water is sampled from the on-site PBNP well. Gross beta and gamma isotopic analytical results for water are obtained by measurements on the solids remaining after evaporation of the unfiltered sample to dryness. Hence, the results are indicated as "on total solids" in Table 10-1. 9.7.4 Air Samples Particulate air filters are allowed to decay at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> before gross beta measurements are made in order for naturally occurring radionuclides to become negligible part of the total activity.

Gross beta measurements serve as a quick check for any unexpected activity that may require 32 immediate investigation.

The particulate air filters are composited quarterly for analyses of long-lived radionuclides such as Cs-134 and Cs-137. Charcoal filters are counted as soon as possible so the 1-131 will undergo only minimal decay prior to analyses.

In order to ensure that the air sampling pumps are operating satisfactorily, a gross leak check is performed weekly. On a quarterly frequency, a reference flow meter is connected across the face of the sampling pump with the particulate and charcoal filter in place. As necessary, the pump's flow rate is adjusted to correspond to that of the flow meter. The pumps are changed out annually for calibration and maintenance beyond what can be accomplished in the field. 9.7.5 Vegetation Vegetation samples consist predominantly of green, growing plant material (grasses and weeds most likely to be eaten by cattle if they were present at the sampling site). Care is taken not to include any dirt associated with roots by cutting the vegetation off above the soil line. 9.7.6 Environmental Radiation Exposure Environmental radiation exposure measurements for the first and second quarter were made with thermoluminescent dosimeters (TLDs). These TLDs consisted of three lithium fluoride chips sealed in black plastic. The TLDs absorb the energy deposited in them by gamma rays. The gamma rays may originate from PBNP produced radionuclides or from naturally occurring radionuclides.

The TLDs remain at the monitoring site for roughly three months prior to analyses and the results are reported as mrem per 7 days. Because the TLDs are constantly bombarded by naturally occurring gamma radiation, even during shipment to and from PBNP, the amount of exposure during transportation is measured using transportation controls with each shipment of TLDs to and from the laboratory.

The doses recorded on the transportation controls are subtracted from the monitoring TLDs in order to obtain the net in situ dose. Third and fourth quarter measurements were made with TLD cards. The TLD card is a small passive detector which integrates exposure through the use of a crystalline phosphorus material, calcium sulfate containing dysprosium.

Each TLD consists of a single Teflon sheet coated with calcium sulfate, which is read in four distinct quadrants to yield four values of exposure.

This dosimeter design provides more precise exposure information by utilizing average of four values. The field exposure reported is the arithmetic average of the four exposure values obtained 33 minus the exposure received while the field TLD is in storage and transit.

The TLD cards will be used in place of the TLD chips. 9.7.7 ISFSI Ambient Radiation Exposure Although the ISFSI fence TLDs are not considered part of the REMIP because of their location directly on site, their results can be used indirectly to determine whether the operation of the ISFSI is having an impact on the ambient environmental radiation beyond the site boundary.

Impacts are determined by comparison of fence TLD results to the results of the monitoring at PBNP site boundary and other selected locations.

10.0 RESULTS Summary of 2001 REMP Results Radiological environmental monitoring conducted at PBNP from January 1, 2001, through December 31, 2001, consisted of analysis of air filters, milk, lake water, well water, soil, fish, shoreline sediments, algae, and vegetation as well as TLDs. The results are summarized in Table 10-1. Table 10-1 contains the following information:

For certain analyses, an LLD which is lower than that required by REMP is used because the lower value derives from the counting time required to obtain the LLDs for radionuclides that are more difficult to detect. For these analyses, both LLDs are listed with the REMP LLD given in parentheses.

The results are discussed in the narrative portion of this report (Section 11). Blank values have not been subtracted from the results presented in Table 10-1. A complete listing of all the individual results obtained from the contracted analytical laboratory and the laboratory's radioanalytical quality assurance results and Interlaboratory Crosscheck Program results are presented in the Appendix.34 Table 10-1 Summary of Radiological Environmental Monitoring Results for 2001 Average +/- Standard Sample Description N LLD (a) Deviation (b) High +/- 2 sigma Units TLD Environmental Radiation 124 1 mrem 1.06 +/- 0.19 1.76 +/- 0.04 mR/7days Control (E-20) 4 1 mrem 1.03 +/- 0.1 1.18 +/- 0.03 mR/7days Air Gross beta 252 0.01 0.023 +/- 0.01 0.059 +/- 0.005 pCi/m3 Control (E-20) Gross beta 52 0.01 0.024 +/- 0.01 0.060 +/- 0.005 pCi/m3 1-131 304 0.030 (0.07) ND -pCi/m3 Cs-134 24 0.05 ND -pCi/m3 Cs-137 24 0.06 ND -pCi/m3 Other gamma emitters 24 0.1 ND -pCi/m3 Milk Sr-89 36 5 ND -pCi/L Sr-90 36 1 1.2 +/- 0.5 2.7 + 0.6 pCi/L 1-131 36 0.5 ND -pCi/L Cs-134 36 5(15) ND -pCi/L Cs-137 36 5(15) ND -pCi/L Ba-La-140 36 5 (15) ND -pCi/L Other gamma emitters 36 15 ND -pCi/L Well Gross beta 4 4 ND -Ci/L Water H-3 4 500 (3000) ND pCi/L Sr-89 4 10 ND pCi/L Sr-90 4 1(2) ND pCi/L 1-131 4 0.5 (2) ND pCi/L Mn-54 4 10(15) ND pCi/L Fe-59 4 30 ND pCi/L Co-58 4 15 ND pCi/L Co-60 4 15 ND pCiiL Zn-65 4 30 ND pCiiL Zr-Nb-95 4 15 ND pCi*L Cs-134 4 15 ND pCi/L Cs-137 4 18 ND pCi/L Ba-La-140 4 15 ND pCi/L Other gamma emitters 4 30 ND pCi/L Algae Gross beta 6 0.25 2.71 +/- 1.05 4.65 +/- 0.44 pCi/g Co-58 6 0.25 ND pCi/g Co-60 6 0.25 ND pCilg Cs-134 6 0.25 ND pCi/g Cs-137 6 0.25 ND pCi/g (a) The required LLD per the PBNP REMP is enclosed in the parentheses.

The average of these TLD results is 1.06 mR/7 days (indicator TLDs, all sites but the Control) and 1.03 mR/7 days at the control location.

These results are not significantly different from each other nor from those observed from 1993 through 2000 (tabulated below in Table 11-1). Therefore, the operation of the plant has had no effect on the ambient gamma radiation.

Table 11-1 Average Indicator TLD Results from 1993 -2001 Year TLD Average Units 1993 0.82 mR/7 days 1994 0.90 mR/7 days 1995 0.87 mR/7 days 1996 0.85 mR/7 days 1997 0.87 mR/7 days 1998 0.79 mR/7 days 1999 0.79 mR/7 days 2000 0.91 mR/7 days 2001 1.06 mR/7 days The annual ISFSI fence TLD results listed in Table 11-3 show the anticipated slow trend upward due to the cask additions each year (one added in December 2001). The North and West fence TLDs continue to record higher doses than the S and E fence TLDs corresponding to the location of the storage units at the NW comer of the site (see Table 11-3). The overall increase in the West Fence TLD for the ISFSI was about 20%. Most of the indicator sites for the ISFSI (Table 11 2) show increases within the expected statistical variation, except E-03. A review 37 of the quarterly data for this sampling site show no appreciable variation for the first two quarters of 2001. However, the third quarter result for E-03 was 1.76 mR/7 days, which is outside of its average range. It appears that this noticeable change is due to the change in TLD types, because no additional casks were placed during the 3 rd quarter of 2001 and indicator site E-30 (located close to the ISFSI) did not see the same increase magnitude.

No impact on the ambient gamma radiation at or beyond the site boundary due to the operation of the ISFSI is indicated.

This radionuclide as well as Cs-137, which are still cycling through the environment, can be attributable to the large-scale atmospheric weapons tests of the 1960s, to 38 Sampling Site Sampling Site the less frequent testing in the 70s and 80s, as well as the Chernobyl accident.

These results are common throughout the Great Lakes region and North America.

The PBNP 2001 average Sr-90 of 1.2 +/- 0.5 pCi/L compares favorably with the 2000 average of 1.2 +/- 0.6 pCi/L, 1999 average of 1.0 +/- 0.3 pCi/L and with the 1997 and 1998 averages, 1.2 +/- 0.5 pCi/L and 1.1 +/- 0.5 pCi/L, respectively, indicating little change. The milk data for 2001 show no radiological effects of the plant operation.

11.3 Air The average annual gross beta concentrations in weekly airborne particulates were within uncertainty at the indicator and control locations (0.023 +/- 0.01 and 0.024 +/- 0.01 pCi/m 3 , respectively) and are similar to levels observed from 1993 through 2000. The results are tabulated below. Table 11-4 Average Gross Beta Measurements in Air Year Average (pCi/m3) 1993 0.022 1994 0.022 1995 0.021 1996 0.021 1997 0.021 1998 0.022 1999 0.024 2000 0.022 2001 0.023 No detectable amounts of 1-131 were found. Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations.

Neither the indicator nor control locations show results, which on average, are significantly different than zero. Be-7, a naturally occurring radionuclide, was measured in quarterly composites of all samples with an average of 0.062 pCi/m 3.This is comparable to the average of 0.064 pCi/m 3 at the control site. Naturally occurring radionuclides are not required to be measured by the PBNP REMP, however, quantification of such nuclides serve as a means to monitor the internal consistency of the vendor's analytical program.

In summary, the air data for 2001 show that the operation of PBNP did not have an impact.39 11.4 Lake Water For the suite of REMP-specified gamma emitting radionuclides, measured concentrations continue to occur as small negative and positive values scattered around zero, indicating no radiological impact from the operation of PBNP. Sr-90 still persists from radioactive fallout. Tritium, in addition to being produced by water-cooled reactors such as PBNP, also is a naturally occurring radionuclide.

The lake water samples collected and analyzed in 2001 for H-3 range from ND (non-detectable) to 227 pCi/L. 11.5 Alae Filamentous algae attached to rocks along the Lake Michigan shoreline are known to concentrate radionuclides from the water with concentration factor over a thousand for certain radionuclides.

Typically, the only fission product observed is Cs-137 with averages over years 1995 -2000 of 0.034, 0.050, 0.030, 0.027, 0.031, and 0.027. No observations above the LLD were made in 2001. The occurrence of Cs-137 in the environment can also be attributed to the fallout of events from the past such as weapons testing and nuclear accidents.

Massive resuspension events due to wind stress redistributes Cs-137 throughout Lake Michigan and makes the Cs-137 more available to the algae. These events are visible on satellite photographs of the Lake. In 1976 after a Chinese weapons test, Cs-137 concentrations in algae reached 1.2 pCi/g. The concentrations of the naturally occurring radionuclides K-40 and Be-7 in the algae continue to be about 100 times higher than the Cs-137. The algae data indicate no plant effects during 2001. 11.6 Fish No specified fission/corrosion radionuclide concentrations in fish greater than the required LLD were found in 2001. Positive results for Cs-137 was identified at the low levels in the edible portions of all 15 fish. The highest value of 0.069 pCi/g is considerably less than the high of 2.8 pCi/g as seen in PBNP samples obtained in the mid-1970s during the Chinese weapons tests. The concentration of naturally occurring K-40 is about 50-100 times higher than the highest Cs- 137 concentration.

There is no indication of a plant effect. 11.7 Well Water All of the isotopic well water results are less than the required LLD. This indicates that PBNP effluents are not getting into the aquifer supplying drinking water to PBNP.40 11.8 Soil Cs-137 from weapons testing and the Chernobyl accident fallout continue to be present in soil samples at about 1% of the levels of naturally occurring K-40. As seen in the following table the average gross beta result is not significantly different from those values observed in the past. There is no indication of a plant effect. Table 11-5 Average Gross Beta Concentrations in Soil Year Activity (pCi/g) 1993 23.6 1994 19.4 1995 18.0 1996 19.4 1997 22.8 1998 20.0 1999 23.1 2000 22.1 2001 23.5 11.9 Shoreline Sediment Shoreline sediment consists of beach sand and other sediments washed up on the Lake Michigan shore. As in soil samples, the only non-naturally occurring radionuclide found in these samples is Cs-137 and its concentration (pCi/g) is at 1% or less of the naturally occurring concentrations of K-40. The Cs-137 concentrations of the shoreline sediment are about one-tenth of that found in soils. The shoreline sediment data indicate no radiological effects of the plant operation.

11.10 Vegetation Although the naturally occurring radionuclides Be-7 and K-40 are found in all of the vegetation samples, the programmatically specified radionuclides are all below the required LLD. The Be-7 and K-40 concentrations are about 100 times higher than the Cs-137 concentrations.

The sampling data gives no indication of a plant effect.41 11.11 Land Use Census In accordance with the requirements of Section 2.5 of the Environmental Manual, a visual verification of animals grazing in the vicinity of the Point Beach Nuclear Plant site boundary was completed on July 24, 2001, to ensure that the milk sampling locations remain as conservative as practicable.

No significant change in the use of pasture lands was noted. Therefore, the existing milk sampling program continues to be acceptable.

12.0 REMP CONCLUSION Based on the analytical results from the 464 environmental samples and from 144 sets of TLDs that comprised the PBNP REMP for 2001, PBNP effluents had no discernable, permanent effect on the surrounding environs.

These results demonstrate that PBNP continues to have good controls on fuel integrity and the waste processing, and the control of effluents from PBNP continues to be acceptable pursuant to the ALARA criteria of 10 CFR 50.34a.42 Environmental, Inc.

1.0 INTRODUCTION

The following constitutes the final 2001 Monthly Progress Report for the Environmental Radiological Monitoring Program conducted at the Point Beach Nuclear Plant, Two Rivers, Wisconsin.

Results of analyses are presented in the attached tables. Data tables reflect sample analysis results for both Technical Specification requirements and Special Interest locations and samples are randomly selected within the Program monitoring area to provide additional data for cross-comparisons.

For gamma isotopic analyses, the spectrum covers an energy range from 80 to 2048 KeV. Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected in soil and sediment samples. Specific isotopes listed are K-40, T1-208, Pb-212, Bi-214, Ra-226 and Ac-228. Unless noted otherwise, the results reported under "Other Gammas" are for Co-60 and may be higher or lower for other radionuclides.

All concentrations, except gross beta, are decay corrected to the time of collection.

All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.1 POINT BEACH NUCLEAR PLANT 2.0 LISTING OF MISSED SAMPLES Expected Collection Sample Type Location Date Reason LW E-01 2/14/01 Sample not received.

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported.

Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.January, 2001 through December, 2001 Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) 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-1 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.

This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada. 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 crosscheck 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 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 available upon request.

Table A-5 list 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 available upon request.

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

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

Attachment A lists acceptance criteria for "spiked" samples.

Out-of-limit results are explained directly below the result.Al 12-31-01 ATTACHMENT A ACCEPTANCE CRITERIA FOR "SPIKED" SAMPLES LABORATORY PRECISION:

All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period. 2.0. Single Measurements Each single measurement is reported as follows: x +/- s where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level). In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for:a background sample. 3.0. Duplicate analyses 3.1 Individual results: For two analysis results; xl+/- sl and X2 +/- S2 Reported result: x s; where x = (1/2) (xi + x2) and s = (1/2) V i + 3.2. Individual results: <LI, <L2 Reported result: <L, where L = lower of LI and L2 3.3. Individual results: x +/- s, <L Reported result: x +/- s if x > L; <L otherwise.

4.0. Computation

of Averages and Standard Deviations

4.1 Averages

and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations.

The average x and standard deviation s of a set of n numbers xi, x 2..* Xn are defined as follows: n n-i 4.2 Values below the highest lower limit of detection are not included in the average.

4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.

4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.

4.5 In rounding off, the following rules are followed:

4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged.

As an example, 11 A43 is rounded off to 11.44. 4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.B-2 POINT BEACH NUCLEAR PLANT APPENDIX C Sampling Program and Locations C-1 POINT BEACH NUCLEAR PLANT Locations Collection Type Analysis Sample Type No. Codes (and Type), (and Frequency)' (and Frequency)b Airborne Filters Airborne Iodine Ambient Radiation (TLD's) Lake Water Well Water Vegetation Shoreline Silt Soil Milk Algae Fish 6 E-1-4, 8,20 6 E-1-4, 8, 20 22 E-1-9, 12, 14-18, 20, 22-32, 34-36, 38,39 5 E-1, 5, 6, 33 1 E-10 8 E-1-4, 6.9,20 5 E-1, 5, 6, 8, 9, 12 8 E-1-4, 6, 8, 9, 20 3 E-11, 19, 21 2 E-5,12 1 E-13 Weekly Weekly Quarterly Monthly Quarterly 3x / year as available 2x / year 2x / year Monthly 3x / year as available 3x / year as available GB, GS, on QC for each location 1-131 Ambient Gamma GB, BS, 1-131 on MC H-3, Sr-89-90 on QC GB, GS, H-3, Sr-89-90, 1-131 GB, GS GB, GS GB, GS GS, 1-131, Sr-89-90 GB, GS GB, GS (in edible portions)SPECIAL COLLECTIONS AND ANALYSES Airborne Filters Liquid Subsoil Water Miscellaneous Water Samples 4 per month 1 per quarter 1 per month 4 per quarter 4-5 per year Sr-89, Sr-90 Sr-89, Sr-90 (comp.)
