EXECUTIVE SUMMARY This Annual Monitoring Report for the period of January 1, 2000, through December 31, 2000, is submitted in accordance with Point Beach Nuclear Plant (PBNP) Units 1 and 2 Technical Specification 15.7.8.4 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, new fuel shipments, non-radioactive chemical releases, circulating water system operation, and leak testing of radioactive sources. During 2000, the following amounts of radioactive material were released via the liquid and atmospheric pathways: Liquid Atmospheric Tritium (Ci) 804 88.1 Particulate (Ci) 0.34 0.0001 Noble Gas (Ci) - 2.82 - Noble gases in the liquids are added to the atmospheric. For the purpose of regulatory compliance with the effluent dose 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 limits. 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 dose objectives of 10 CFR 50, Appendix I. LIQUID RELEASES Dose Category Calculated Dose Appendix I Dose Whole body dose 0.008 millirem 6 millirem Organ dose 0.009 millirem 20 millirem ATMOSPHERIC RELEASES Dose Category Calculated Dose Appendix I Dose Organ dose 0.04 millirem 30 millirem Noble gas dose to the skin 0.001millirem 30 millirem Noble gas dose to the whole body 0.0007 millirem 10 millirem Noble gas beta air dose 0.0003 millirad 40 millirad Noble gas gamma ray air dose 0.0007 millirad 20 millirad The results show that during 2000, the doses from PBNP effluents were a small percentage (~ 0.15% at the most) of the Appendix I dose objectives and therefore continue 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 2000 Radiological Environmental Monitoring Program (REMP) collected 470 samples for radiological analyses and 142 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 2000, the ISFSI contained a total of 12 ventilated storage casks (VSC-24). During 2000, 4 casks were 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 2000 confirms that the effluent control program at PBNP ensures that its operations minimally impacts the environs. 2

Part A EFFLUENT MONITORING 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 dose 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 dose 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 (RECM). Leakage of radionuclides from the fuel storage containers at the ISFSI is not expected due to the design of the containers. 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 (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, the annual dose is calculated to the hypothetical maximally exposed individual (MEI). The MEI is assumed to reside at the site boundary in the highest χ/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 dose objectives is presented in Table 2-1. The conservatively calculated dose to the MEI is a very small fraction of the Appendix I dose objective. 4
