SUMMARY

l l Pursuant to Part 50.34a of Title 10 of the Code of Federal Regulations (10 CFR 50.34a), the operation of the Point Beach Nuclear Plant (PBNP) should be conducted so as to keep the levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable !

(ALARA). Furthermore,10 CFR 20.1302 directs PBNP to make the appropriate surveys of j radioactive materials in effluents released to unrestrictee ud controlled areas and of the environs I around PBNP. Therefore, in addition to monitoring effluents, PBNP has a Radiological l Environmental Monitoring Program (REMP) in order to verify that the appropriate controls have !

been applied to effluents prior to release. This Annual Monitoring Report for the period of )

January 1,1998, through December 31,1998, is submitted in accordance with Point Beach j Nuclear Plant Unit Nos. I and 2 Technical Specification 15.7.8.4 and filed under Docket Nos. j 50-266 and 50-301 for Facility Operation License Nos. DPR-24 and DPR-27, respectively. The j 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, j During 1998, liquids containing 299 curies of tritium and 0.377 curies of other radionuclides were released from PBNP. Airborne releases consisted of 73.4 curies of tritium,6.46 curies of noble gases, and 0.295 millicuries of particulate radioactive material. For the purpose of regulatory compliance with the effluent dose objectives of Appendix I to 10 CFR 50, doses from j effluents are calculated for the hypothetical maximally exposed individual (MEI) and compared '

to the Appendix Ilimits. Doses less than or equal to the Appendix I values are considered to be evidence that PBNP releases are ALARA. As such, the radiation exposure to the MElis maximized with respect to occupancy, food consumption, and other uses of this area so that the MEI represents an individual with reasonable deviations from the average for the general _

population in the vicinity of PBNP. Doses are calculated for the adult, teen, child, and infant age groups. 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 1 Dose I Whole body dose 0.004 millirem 6 millirem Organ dose 0.004 millirem 20 millirem i

Noble gas dose to the skin 0.003 millirem 30 millirem Noble gas dose to the whole body 0.002 millirem 10 millirem Noble gas beta particle air dose 0.001 millirad 40 millirad Noble gas gamma ray air dose 0.002 millirad 20 millirad The results show that during 1998, the doses from PBNP effluents were a small fraction of the Appendix I dose objectives and therefore continue to be ALARA.

The 1998 REMP collected 808 samples for radiological analyses and 126 sets of thermoluminescent dosimeters were used to measure ambient radiation in the vicinity of PBNP.

Samples collected consisted of lake and well water, soil, vegetation, milk, soil, shoreline sediments, algae, fish, as well as particulate and radioiodine air samples. 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.

Two lake water samples had higher than normal tritium concentrations. These samples were obtained during periods which coincided with the discharge of waste holdup tanks. Although the tritium results from these samples were higher than normal H-3 concentrations in the water, the results verified that the controls PBNP applies to discharges, to keep the resulting effluent concentrations to a small fraction of the applicable 10 CFR 20 limit, had been applied correctly.

The highest measured concentration was at C.1 % of the applicable limit. Fallout radionuclides from atmospheric weapons testing and from Chernobyl still are present at very low concentrations in some samples: Sr-90 in milk and Cs-137 in soil, vegetation, and fish.

Therefore, based on the REMP radioanalytical results, PBNP effluents had a minimal impact upon the environment during 1998.

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

1.0 BASIS The Point Beach Nuclear Plant's (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 so as 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) l 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) limit 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. This monitoring requirement (also found in General Design Criterion (GDC) 64 of Appendix A to 10 CFR 50 and in PBNP ,

GDC 17) is implemented in order to control effluent releases as required by PBNP GDC 70 and GDC 60 of Appendix A to 10 CFR 50. PBNP GDC 70 and GDC 60 of Appendix A to 10 CFR 50 also address the need for control of solid waste material.

In order to accomplish the required monitoring, PBNP monitors liquid, airborne, and solid waste streams. 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. Results ofisotopic analyses are used to adjust the release rate of discrete volumes ofliquid and atmospheric wastes (from liquid waste holdup tanks and from gas decay tanks) so that the concentrations of radioactive material in the air and water beyond PBNP are below the ,

regulatory concentration limits in Appendix B to 10 CFR 20. Solid wastes are shipped offsite for disposal at an NRC licensed facility. The amount of radioactisity in the solid waste is determined prior to shipment so that the material will comply with the applicable Department of Transportation regulations as well as NRC regulations.

2.0 RADIOACTIVE LIQUID RELEASES The total radioactive liquid release, excluding tritium for this reporting period, was 3.77E-01 curies. This consisted entirely of processed radioactive waste. There were no detectable curies in either Unit I steam generator blowdown and in Unit 2 steam generator blowdown. The retention pond had a small amount of Sr-90 in March and some Na-24 in June. ;

The total tritium release for this reporting period was 2.99E+02 curies. This consisted entirely of processed radioactive waste. There was no detectable tritium measured either in Unit 1 steam generator blowdown, in Unit 2 steam generator blowdown, or in retention ,

pond effluent. I V

. 2.1 1998 Circulating Water Radionuclide Release Summary i

Radioactive liquid releases _via the circulating water discharge are summarized by I individual source and total curies released on a monthly basis and presented in Table 2-1 2.2 1998 Isotopic Composition of Circulating Water Discharges The isotopic composition of circulating water discharges during the current reporting period is presented in Table 2-2.

2.3 Subsoil Drain System Releases of Tritium The quarterly and annual results of monitoring the subsoil or " beach" drains is presented in Table 2-3. For the first time since 1986, tritium (1E-05 Ci/cc) was found in one of the monthly samples. No tritium was observed in any of the other drains during the same month or in the same drain the preceding and following' months. These drains include rainwater runoff as well as ground water drainage.

Therefore, it is unlikely that tritium would occur in only one drain if it were actually present. However, because we have no other data to refute the presence of tritium, the total amount,2.87E-03 Ci, from this drainage system for a August 1998 is reported in Table 2-3. This small amount is 9.6E-04 percent of the total tritium released in PBNP liquids. .

- Indicates no sample to analyze because of zero flow.

2.4 Doses From Liauid Effluent Doses from liquid effluent are calculated using the methodology of the Offsite

! Dose Calculation Manual (ODCM). The ODCM methodology is based on the guidance of Regulatory Guide 1.109," Calculation of annual doses to man from

routine releases of reactor effluents for the purpose of evaluating compliance with L 10 CFR Part 50, Appendix I." For compliance with 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 x/Q sector and is'

. maximized with respect to occupancy, food consumption, and other uses of this L 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

l. the calculated doses to the 10 CFR 50, Appendix I dose objectives is presented in Table 2-4.

1 2.5 Land Application of Sewage Sludge i

The Wisconsin Department of Natural Resources has approved the disposal of PBNP !

sewage by land-application on various Wisconsin Electric Power Company properties l surrounding the Point Beach Nuclear Plant. These sewage sludges, which may contain

. trace amounts of radionuclides, are applied in accordance with methodologies approved by the NRC on January 13,1988, pursuant to 10 CFR 20.302(a). The approved j methodology required 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 radiological inputs to the sewage system for all but naturally occurring radionuclides. This was verified by sludge analyses, using the environmental LLD criteria, which found no byproduct radionuclides in the sludge after the controls and modifications were completed. Currently, the sludge is routinely monitored and no radionuclides attributable to PBNP have been found. There were no disposals of sewage by land application during 1998.

3.0 RADIOACTIVE AIRBORNE RELEASES I The release paths contributing to radioactive airborne release totals during this reporting period were the auxiliary building vent stack, drumming area vent stack, gas stripper building vent stack, Unit I containment purge stack, Unit 2 containment purge stack, combined air ejector decay duct exhaust and turbine building ventilation exhaust.

3.: Radioactive Airbome Release Smumary Radioactivity released in airborne effluents for 1998 are summarized in Table 3-1.

3.2 Doses From Airbome Effluent Doses from airbome effluent are calculated for the MEI following the methodology of Regulatory Guide 1.109. In addition to the MEl doses, the energy deposited by beta particles and gamma rays in air also is calculated and compared to the corresponding Appendix I dose objectives. A comparison of the annual Appendix I dose limits for atmospheric effluents to the highest organ dose and the noble gas doses calculated using ODCM methodology is found in Table 3-2. The doses demonstrate the releases from PBNP to the atmosphere continue to be ALARA.

10.0 BASIS FOR RADIOLOGICAL ENVIRONMENTAL MONITORING I

The objective of the PBNP REMP is to measure ambient radiation levels and to collect and analyze air, water, vegetation, fish, and soil samples for their radionuclide content in order to determine whether the operation of the PBNP has radiologically impacted the surrounding environment. These measurements also serve as a check of the efficacy of PBNP effluents controls. The REMP fulfills the requirements of 10 CFR 20.1302, PBNP l General Design Criterion (GDC) 17, GDC 64 of Appendix A to 10 CFR 50, and Sections '

I . IV.B.2 and IV.B.3 of Appendix I to 10 CFR 50. 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.

For the aquatic environment, the samples include water as well as the biological integrators, 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 oflake 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 terrestrial and atmospheric environments are united by the air-grass-cow-milk exposure pathway. 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 remains conservative with respect to dose calculations for PBNP effluents. The dose calculations assume that the dairy cattle are located at the 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.

11.0 PROGRAM DESCRIPTION 11.1- Results Reportine Convention The PBNP REMP results in this Annual Report are reported directly as measured by a detector which can meet the required Lower 12 vel of Detection (LLD) as specified in Table 2-2 of the Environmental Manual, whether positive, negative or zero. No results are reported as <LLD. This reporting convention follows the recommendation made in NUREG-0475 (1978) " Radiological Environmental 20

p l

Monitoring by NRC Licensees for Routine Operations of Nuclear Facilities Task Force Report," and in Health Physics Society Committee Report HPSR-1 (1980)

" Upgrading Environmental Radiation Data" released as document EPA 520/1 012 and in more recent documents such as ANSI N42.23-1996, " Instrument Quality Assurance for Radioassay Laboratories;" ANSI N13.30-1996,

" Performance Criteria for Radiobioassay;" and DE91-013607," Environmental

, Regulatory Guide for Radiological Effluent Monitoring and Environmental Surveillance."

The LLD or Lower Limit of Detection 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 tu count the sample in order to ;

achieve the desired LLD depends upon the sample size. Hence, the desired LLD _

l 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 the statistical parameters (i.e., average, standard deviation) presented in this report.

I1.2 Samoling Parameters Samples are collected at the frequency indicated in Table Il-1 from the locations described in Table Il-2 and shown in Figures I l-1,11-2, and Il-3. (The latter two figures show sampling locations not shown in preceding figures due to space limitations. The minimum acceptable sample size is found in Table Il-3.

11.3 Deviations from Reauired Collection Freauency Deviations from the collection frequency given in Table 11-1 are allowed because of hazardous conditions, automatic sampler malfunction, seasonal unavailability, and other legitimate reasons (Section 2.2.6 of the Environmental Manual). The following deviations from the scheduled sampling and frequency occurred during 199fs:

21 i

i Two TLDs placed at E-28 and E-32 were lost in the field during the first quarter of1998.

I1.4 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 I l-4) for the State from sites which are near PBNP sampling sites or are co-located. A typical, co-located sampling site (E-04) where air particulate and iodine as well as vegetation samples are collected is shown in Figure 11-4. This also is a site where precipitation samples are collected for the State. The results of the State monitoring program are available from the Radiation Protection Unit of the WI Department of Health and Family Services.

I 11.5 Analytical Parameters The types of analyses and their frequencies are given in Table Il-5. The LLDs for the various analyses are found in the Results Section (12) of this report (Table 12-

1) with the summary of the REMP results. All environmental LLDs listed in Table 2-2 of the Environmental Manual (and also in Table 12-1) were achieved during 1998.

I1.6 Brief Description of Analytical Parameters in Table i1-5 I1.6.1 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, I-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, TI-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.

I1.6.2 Gross Beta Analysis Gross beta analysis is a non-specific analyses which 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 which may require additional, immediate analyses.

I1.6.3 Water Samples Water samples include both Lake Michigan and well water. The Lake Michigan samples are collected along the shoreline (Figure I l-5) at five locations north and south of PBNP. The well is 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 11-5.

to become negligible part of the total activity. Gross beta measurements serve as a quick check for any unexpected activity that may require further, immediate investigation. The particulate air filters are composited

( . quanerly for analyses oflong-lived radionuclides such as Cs-134 and Cs-137. Charcoal filters are counted as soon as possible so that the I-131 will

. undergo only minimal delay prior to analyses.

In order to insure 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 I with the particulate and charcoal filter in place (Figure 11-6). 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 that which can be accomplished in the field.

I1.6.5 Vegetation Vegetation samples consist predominantly of green, growing plant ;

l material (grasses and weeds most likely to be eaten by cattle if they were i

! present at the sampling site). Care is taken not to include any dirt l associated with roots by cutting the vegetation off above the soil line.

I1.6.6 Environmental Radiation Exposure Environmental radiation exposure measurements are made with

, thermoluminescent dosimeters (TLDs). Each TLD used in the PBNP l REMP consists of three lithium fluoride chips sealed in black plastic. The l TLDs absorb the energy deposited in them by gamma rays. The gamma rays may originate from PBNP produced radionuclides or from naturally e occurring radionuclides. The TLDs remain at the monitoring site for l roughly three months prior to analyses and the results are reported as l mrem per 7 days. Because the TLDs are constantly bombarded by j 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 dose recorded on the transportation controls are subtracted from the monitoring TLDs in order to obtain the net in situ dose.

l I 12.0 RESULTS Summary of 1998 REMP Results l Radiological environmental monitoring conducted at the Point Beach Nuclear Plant from January 1,1998 through December 31,1998 consisted of air filters, milk, lake water, well

, water, soil, fish, shoreline sediments, algae, vegetation, and TLDs. The results are summarized in Table 12-1.

Table 12-1 contains the following information:

Sample: the type of the sample medium

Description:

the type of measurement LLD: the a priorilowerlimit of detection N: the number of samples analyzed Low: the lowest measured value

its associated 2s counting error l Average: the average value

the standard deviation of N samples

High: the highest measured value its associated 2s counting error L Units: the units of measurement Additional information also is presented in this table. Not all of the results in Table 12-1 were required by the current PBNP Radiological Environmental l Monitoring Program (REMP). Non-REMP items and values are noted by an asterisk (*). For example, soil is not a good indicator for assessing small l incremental releases which might occur during routine operation of PBNP (Regulatory Guide 4.5). However, soil is satisfactory for establishing long-term trends. Because soil was part of the pre-operational monitoring program, soil collection and analyses has continued for use as a long-term indicator. For certain l analyses, an LLD which is lower than that required by REMP is used because the l

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 13) Blank values have not been subtracted from the results presented in Table 12-1. A complete listing of all the

, individual results obtained from the contracted analytical laboratory and the laboratory's radioanalytical quality assurance results and EPA Interlaboratory Crosscheck Program results are presented in the Appendix.

o 13.0 DISCUSSION 13.1 TL.Ds All TLD results except first quarter E-39 for the reporting period were within the range of values recorded in previous years. Although the average for 1998 (0.79

, 0.13) is lower than previous years, the difference is not statistically different from 1996 (0.85 i 0.12) and 1997 (0.87 0.11). Therefore, the TLD results indicate '

that the measured environmental doses are dominated by natural sources and not by PBNP effluents. The anomalous result of 1.25 0.05 mRn days at E-39 occurred during the first quarter; however, no previous data exists for this site because it was added in 1998. All subsequent readings from this site resulted in within the reported values for the other TLD monitoring sites.

13.2 Milk Radionuclide concentrations in milk continue to be indistinguishable from zero except for Sr-90 and Cs-137. These two radionuclide, which are still cycling through the environments, are attributable to the large scale atmospheric weapons

. tests of the 1960's, to the less frequent testing in the 70's and 80's, and to the Chernobyl accident. That these results are common throughout the Great Lakes region and North America. The PBNP average Sr-90 of 1.1 0.5 pCi/l compares well with the 1997 average (1.2 0.5 pCi/.1), indicating little change 13.3 Airi The 1998 low, average, and high values are not statistically different from the corresponding 1997 values. The I-131 concentration distribution for 1998 also is similar to that of 1997, with the average concentration being roughly zero. Figure 13-1 shows that the 1998 frequency distribution for the measured I-131

. concentrations in air are symmetrical around zero with the highest frequency 3

falling in the -2 to +2 pCi per 1000 m interval. As discussed in Section 11.1, the statistical nature of radioactive decay produces this type of distribution when no I-131 activity is present or well below the lower level of detection.

i Be-7, a naturally occurring radionuclide produced in the air by the collision of cosmic rays with atoms of oxygen (ieO), nitrogen ( "N), and carbon (i2C) was found in all of the air samples (see Appendix). About 180,000 curies of Be-7 are ,

produced in the air over the State of Wisconsin each year based on the production !

rate found in Table 3.3 of NCRP Report No. 94, Exposure of the Population in the United States and Canadafrom Natural Background Radiation (1987).

13.4 Lake Water For the suite of REMP specified gamma emitting radionuclides, measured concentrations continue to occur as small negative and positive values scattere'd around zero. 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. Many of these are within the upper range of positive results obtained from water " blanks"in past years, 148

101 pCi/l. Two of the 20 analyses produced considerably higher results than the others, both occurring within the fourth quarter: E-01 (1264 125 pCi/1) and E-12 (882 113 pCi/l). As in the past, this type of result occurs when environmental sampling occurs during or within a short period of time following the discharge of a waste holdup tank.

Note that E-12 is in the discharge channel and E-01 is about one mile south of l

PBNP. These sampling sites are the ones most affected by these discharges.

13.5 Aleae Filamentous algae attached to rocks along the Lake Michigan shoreline are known to concentrate radionuclides from the water with concentration factor over a 39

?

l thousand for certain radionuclides. The algae obtained from the vicinity of the discharge fiume, E-12, have minute concentrations of Cs-137, Co-60, and Co-58.

all of which were discharged from PBNP during 1998. The highest measured concentration of Cs-137 at 0.055 0.025 pCi/g is similar to the 1997 concentration of 0.038 i 0.012 pCi/g which is consistent with the cycling of this i

+ radionuclide within the Great Lakes. Massive resuspension events due to wind stress redistributes Cs-137 throughout Lake Michigan and make 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 compared to the 1998 PBNP average result of 0.027 0.014 pCi/g.

13.6 Ej5h The only specified radionuclide statistically different from zero in fish is Cs-137.

Cs-137 was identified at the low levels given in Table 12-1 in the edible portions of all eight analyzed. The highest value of 0.131 pCi/g is slightly elevated from 1997 (0.082 pCi/g); however, it is down significantly from the high of 2.8 pCi/g as seen in PBNP samples obtained in the mid-1970s during the Chinese weapons tests.

13.7 Well Water All of the isotopic well water results are small positive and negative values indistinguishable from zero.

13.8 Soil Cs-137 from weapons testing and Chernobyl incident fallout continue to be present in soil samples collected as part of the PBNP REMP.

13.9 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.

13.10 Vegetation 40

Although the naturally occurring radionuclides Be-7 and K-40 are found in all of the vegetation samples, the only programmatically specified radionuclide found is Cs-137. This result is from a sample obtained at the campground area of Point Beach State Park. Fallout Cs-137 from the 1960s which had been incorporated in the trees growing at that time period now is being recycled as the trees are being

. used in campfires and the ashes are scattered on the ground. The occurrence of Cs-137 in wood ash has been reported in Wisconsin and other states.

13.11 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 September 1,1998 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.

14.0 CONCLUSION

Based on the analytical results from the 808 environmental samples and from 126 sets of TLDs that comprised the PBNP REMP for 1998 PBNP effluents had a minimal,if any, measurable affect on the PBNP environs. These results demonstrate that the control of effluents from PBNP continues to be acceptable pursuant to the ALARA criteria of 10CFR50.34a.

POINT BEACH NUCLEAR PLANT

1.0 INTRODUCTION

The following constitutes the current,1998 Monthly Progress Report for the Environmental Radiological Monitoring Program conducted at the Point Beach Nuclear Plant, Two Rivers, Wisconsin. i Results of completed analyses are presented in the attached tables. Missing entries indicate analyses that are not completed. These results will appear in subsequent reports. Data tables reflect sample l,

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.

1*

l Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled. None of the media sampled during the current month contained radioactivity attributable to the operation of Point Beach Nuclear Plant.

For all gamma isotopic analyses, the spectrum is computer scanned from 80 to 2048 kev. Specifically I included are Mn-54, Fe-59, Co 58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, I-131, Ba La-140, Cs-134, l Cs 137, Ce-141, and Ce-144. Naturally occurnng gamma-emitters, such as K-40 and Ra daughters, are I

frequently detected in soil and sedunent 6amples. Specific isotopes listed are K-40, TI-208, Pb-212, Bi-214, Ra-226 and Ac-228. Unless noted otherwise, the results reported under "Other Gammas" are for l CMC and may be higher or lower for other radionuclides.

l 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 ;

l Samples.

APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Teledyne's Midwest Laboratory participates in intercomparison studies admuustered by U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in Appendix A. Also reported are results of InternationalIntercomparison and Teledyne testing of TLD s, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

January,1998 through December,1998

Annendix A Interlaboratory Comparison Proeram Resnita Talsdyne Brown Engineering Environmental Services Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the f:rmulation 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) contaming concentrations of radionuclides known to the issuing agency but not to participant laboratories. He purpose of such a program is to prsvide an independent check on the laboratory's analytical procedures and to alert it to 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 controllimits indicate a need to check the instruments or procedures used. ,1 Th2 results in Table A-1 were obtained through participation in the environmental sample crosscheck -

pr: gram for milk, water and air filters during the past twelve months. Data for previous years is t.vailable upon request.

This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various InternationalIntercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.

Also Teledyne testing results are 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.

Trble 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 svaluation program. .

He 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.

The Environmental Me .rements Laboratory provides the following nuclear species : Air Filters, Soil, Tissue, ,

Vegetation and Water. Taedyne does not participate in the Tissue program

Results are reported in Bq/L*' with the following exceptions: Air Filter results are reported in Bq/ Filter, Soil results are reported in Bq/Kg, Vegetation recults are reported in Bq/Kg. The results of elemental Uranium are ,

_ reported in ug/ filter, g, or ml.

Teledyne results are reported as the mest.t of three determinations

standard deviation.

The EML result listed is the mean of reulicate determinations for each nuclide*the standard error of the mean.

h control limits are reperted by EML and are established from percentiles of historic data distributions (1H-1992). h evaluation of this historic data and the development of the controllimits is presented in DOE reprt EML-564.

r l l

Data Reoorting Conventions 1.0. 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:

xis where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L I where L = the lower limit of detection based on 4.66c uncertainty for a background sample. ,

l l

3.0. Duplicate analyses 3.1 Individual results: x1 t s1 x2 i s2 Reported result: xis wl.ere x = (1/2)(x1 + x2) l s = (1/2)k sf + s! l 3.2. Individual results: <Li

<L2 -

l Rer,c ned result: <L 1

where L = lower of Li and L2 l 3.3. Individual results: x i s

<L Reported result: xis if x 2 L;

<L otherwise B- 2

4.0. Comentation of Averaees and Standard Deviatinns 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 i and standard, j deviation s of a set of n numbers xi, x2. . . xn are defined as follows: l

' I '

x= Ix s= I (x- x)2 n-1 4.2 Values below the highest lower limit of detection are not included in the average.

4.3 If all of the 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 erroris myurted.

4.5 In rounding off, the following rules are followed:

f 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,11.443 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.
