SUMMARY

PILGRIM NUCLEAR POWER STATION RADIOACTIVE EFFLUENT AND WASTE DISPOSAL REPORT INCLUDING METEOROLOGICAL DATA JANUARY 01 THROUGH DECEMBER 31, 2000 INTRODUCTION This report quantifies the radioactive gaseous, liquid, and radwaste releases, and summarizes the local meteorological data for the period from January 01 through December 31, 2000. This document has been prepared in accordance with the requirements set forth in the Pilgrim Nuclear Power Station (PNPS) Technical Specifications and Revision 1 of Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Material in Liquid and Gaseous Effluents from Light Water Cooled Nuclear Power Plants".

In July 1999, ownership and control of Pilgrim Station was transferred from Boston Edison Company to Entergy Nuclear Generation Company. Although the operating license of the plant was transferred with the ownership, no changes were made in the operation of the plant which would affect the releases of radioactivity to the environment, as summarized in this report.

The quantity of radioactive material released from PNPS was determined from sample analyses and continuous on-line monitoring of gaseous releases from the main stack, reactor building vent, turbine building, and various decontamination facilities, and liquid releases into the discharge canal.

The quantity and volume of radioactive waste which was shipped offsite from PNPS for processing and burial were determined from data contained on the radwaste shipping documentation. The meteorological data were obtained from monitoring instruments located on the 220-foot meteorological tower located at Pilgrim Station.

GASEOUS EFFLUENTS Gaseous radioactive releases for the reporting period are quantified in Tables 2.2-A, 2.2-B, and 2.2-C. Radioactive noble gases released during the period totaled 1070 Curies. Releases of radioactive particulates and iodines totaled 0.015 Curies, and tritium releases totaled 88 Curies. No gross alpha radioactivity was detected in gaseous effluents.

Noble gases released in gaseous effluents resulted in a maximum total body dose of 0.13 mrem, with a corresponding skin dose of 0.98 mrem. The release of radioactivity in gaseous effluents from PNPS during 2000 resulted in a total body dose to the maximum-exposed hypothetical individual of about 0.63 mrem from radioactive particulates, iodines, and tritium. The maximum hypothetical dose to any organ from radioactive particulates, iodines, and tritium was about 0.79 mrem. All of these maximum doses occurred to a hypothetical individual located on property under Entergy control. The maximum, hypothetical total body dose from the combined release of radioactivity in gaseous effluents was 0.79 mrem. The cumulative total body dose to the entire population within 50 miles of PNPS from combined gaseous effluents was about 0.58 person-rem. The average individual living within 50 miles of PNPS received a total body dose of about 0.00014 mrem from combined gaseous effluents released during 2000.

The maximum individual doses from gaseous radioactive effluents were compared to the applicable ODCM dose limits. Noble gas doses were less than 7% of the corresponding 10CFR50 dose objectives. Maximum doses resulting from releases of particulates, iodines, and tritium in gaseous effluents were less than 6% of corresponding 10CFR50 objectives.

During review of several years of past analytical results for strontium-89 and strontium-90 releases in gaseous effluents, an error was identified in the results provided for the fourth quarter of 1999. The error involved an incorrect sample collection time used for decay-correcting the analytical results, resulting in an 86% increase in the activity value for Sr-89. Since no Sr-90 was detected during the period, there was no impact on the results for this nuclide. No other nuclides were affected by this error. Revised tables showing the updated values for gaseous effluent releases are included in Appendix D. A vertical bar in the right margin of each page indicates the updated section.

An analysis was performed to assess the impact of the erroneous Sr-89 value used in the 1999 dose assessments. Since Sr-89 accounted for only a minor portion of the total activity in gaseous effluent during the period, its contribution to the maximum organ dose was less than 1% of the value of 1.01 E-01 mrem reported for the fourth quarter of 1999.

LIQUID EFFLUENTS Liquid radioactive releases for the reporting period are quantified in Tables 2.3-A and 2.3-B. Liquid effluents released into the discharge canal contained 0.21 Curies of fission and activation products, and 10.7 Curies of tritium. No dissolved/entrained noble gases or gross alpha radioactivity were detected in liquid effluents.

The release of radioactivity in liquid effluents from PNPS during 2000 resulted in a total body dose of about 0.01 mrem to the maximum-exposed hypothetical individual. The maximum hypothetical dose to any organ from liquid effluents was about 0.058 mrem. The cumulative total body dose from liquid effluents to the entire population within 50 miles of PNPS was about 0.102 person-rem. The average individual living within 50 miles of PNPS received a total body dose of about 0.000025 mrem from liquid effluents released during 2000.

The maximum individual doses from liquid radioactive effluents were compared to the applicable ODCM dose limits. All doses from liquid effluents were less than 2% of their corresponding effluent control limit. In addition, all quarterly average concentrations of radioactivity in liquids released to Cape Cod Bay were less than 0.4% of the corresponding limits.

METEOROLOGICAL DATA Meteorological joint frequency distributions are listed in Appendix A. The data recovery for the annual reporting period was 92%. The predominant wind direction was from the south-southwest, which occurred approximately 13% of the time during the reporting period. The predominant stability class was Class E, which occurred about 36% of the time during the reporting period OFFSITE AMBIENT RADIATION MEASUREMENTS Ambient radiation exposure was evaluated to complete the assessment of radiological impact on humans. A small number of thermoluminescent dosimeters (TLDs) indicated an increase in ambient radiation exposure on Entergy property in close proximity to the station, resulting from nitrogen-16 contained within the plant steam system. The dose to a hypothetical member of the public accessing such areas on Entergy property during 2000 was estimated as being about 2.4 mrem. There was no measurable increase during 2000 in ambient radiation measurements at the location of the nearest resident to PNPS.

6

The collective total body dose to a maximum-exposed hypothetical individual from radioactive gases, liquids, and ambient exposure resulting from PNPS operation during 2000 was calculated as being 3.2 mrem. This amount is about 1% of the typical dose of 300 to 400 mrem received each year by an average person from other sources of natural and man-made radiation. Although this calculated collective dose occurs to a maximum-exposed hypothetical individual, it is also well below the NRC dose limit of 100 mrem/yr specified in 10CFR20.1301, as well as the EPA dose limit of 25 mrem/yr specified in 40CFR1 90. Both of these limits are to be applied to real members of the general public, so the fact that the dose to the hypothetical maximum-exposed individual is within the limits ensures that any dose received by a real member of the public would be smaller and well within any applicable limit.

RADIOACTIVE SOLID WASTE DISPOSAL Solid radioactive waste shipped offsite for processing and disposal during the reporting period is described in Table 8.0. Approximately 951 cubic meters of solid waste, containing 1590 Curies of radioactivity, were shipped during the reporting period.

CONCLUSION The PNPS Offsite Dose Calculation Manual contains effluent controls to limit doses resulting from releases of radioactivity to the environment. None of the effluent controls associated with liquid or gaseous effluents were exceeded during the reporting period, as confirmed by conservative dose assessments performed at weekly and monthly intervals. Conformance to the PNPS ODCM effluent control limits ensures that releases of radioactivity in liquid and gaseous effluents are kept as low as reasonably achievable in accordance with 10 CFR Part 50, Appendix I. Compliance with the ODCM also demonstrates that requirements of the Environmental Protection Agency's nuclear fuel cycle standard, 40CFR190.10, Subpart B, have been met. Based on the dose assessment results for 2000, there was no significant radiological impact on the general public from PNPS operation.

2.0 RADIOACTIVE EFFLUENT DATA Radioactive gaseous and liquid releases for the reporting period are given in the standard format presented in Tables 1A, 1B, 1C, 2A, 2B, and Supplemental Information table from NRC Regulatory Guide 1.21 (Reference 1) format.

2.1 Supplemental Effluent Release Data Supplemental information related to radioactive gaseous and liquid releases for the reporting period are given in the standard NRC Regulatory Guide 1.21 format in Table 2.1.

2.2 Gaseous Effluent Data Gaseous radioactivity is released from Pilgrim Station to the atmosphere from the main stack, reactor building vent, turbine building, and various decontamination facilities. Combined gaseous effluent releases from all release points are summarized in Table 2.2-A. No alpha activity was detected on any of the particulate filters collected during the reporting period. The total gaseous releases for various categories of radionuclides, as well as the corresponding average release rates, can be summarized as follows:

"* Noble gases: 663 Ci, 21 pCi/sec

"* Particulates and iodines with 0.015 Ci, 0.00048 jiCi/sec half-life greater than 8 days

"* Tritium: 88 Ci, 2.8 pCi/sec Effluent releases from the main stack are detailed in Table 2.2-B. The main stack is an elevated release point with a height of approximately 400 feet above sea level. The main stack is located about 700 feet west-northwest of the reactor building.

Ground-level effluent releases are detailed in Table 2.2-C. Data in this table includes releases from the reactor building vent, turbine building, and assorted equipment decontamination facilities (e.g.,

hot machine shop, carbon dioxide pellet decon trailer, plastic media decon trailer, etc.) used during the period. Due to the close proximity of the reactor building, both of these release points are considered to be mixed-mode/ground level release points.

During the period of 06-08 October 2000, problems occurred with a loop seal in the augmented offgas (AOG) system which processes radioactive gaseous emissions. The AOG functions primarily by holding up radioactive noble gases coming from the main condenser air ejector, allowing them to undergo radioactive decay prior to being released via the Main Stack. The problem with the loop seal allowed small amounts of noble gases to be released into the offgas retention building. This building is ventilated via the reactor building ventilation system. Radiation monitors on the ventilation system alerted PNPS personnel of the increased offgas activity, and samples were collected and analyzed.

This event was treated as an abnormal release, and time-specific meteorology was applied to calculate dose impact from this event. Noble gas releases associated with this event are summarized in Table 2.2-C, for the period of October-December 2000.

2.3 Liquid Effluent Data Liquid radioactivity is released from PNPS to Cape Cod Bay via the circulating water discharge canal.

These effluents enter Cape Cod Bay at the outfall of the canal, which is located about 1100 feet north of the reactor building.

Liquid effluent releases are summarized in Table 2.3-A. Detailed breakdowns for individual radionuclides are listed in Table 2.3-B. No dissolved/entrained gases or gross alpha radioactivity were detected in liquid effluents released during the reporting period. Total releases for the various categories of radionuclides, as well as their corresponding mean concentrations, can be summarized as follows:

"* Total Effluent Volume: 874,000 Liters

"* Total Dilution Volume: 5,090,000,000 Liters

"* Fission/Activation products: 0.21 Ci, 0.000000042 pCi/mL

"* Tritium: 10.7 Ci, 0.0000021 [iCi/mL

"* Dissolved/entrained noble gases: Not Detected 9

3.0 METEOROLOGICAL DATA Meteorological data (Reference 2) are summarized for the reporting period in Appendix A, in the standard joint frequency distribution format as given in NRC Regulatory Guide 1.21.

The predominant meteorological conditions observed during the annual reporting period can be summarized with their corresponding frequencies as follows:

"* Stability Class: Class E, 36%

"* Wind Direction (from): South-southwest, 13%

"* 33-ft Wind Speed: 4-7 mph, 53%

"* 220-ft Wind Speed: 13-18 mph, 32%

There were a limited number of instances when data collection from the 220-ft meteorological tower was not continuous. Typically, such data losses were attributed to lightening strikes, loss of power, malfunction of the sensors, and/or malfunction of the digital dataloggers. Data recovery for the period was about 92% for the 33-ft level, and 92% for the 220-ft level of the tower. These data recovery values exceed the NRC's recommended annual recovery goal of 90%.

22

4.0 MAXIMUM INDIVIDUAL DOSES Doses to the maximum exposed individual resulting from radionuclides in effluents released offsite were calculated using methods presented in the PNPS Offsite Dose Calculation Manual (ODCM, Reference 3), NRC Regulatory Guide 1.109 (Reference 4), NRC Regulatory Guide 1.111 (Reference 5), and the Pilgrim Station Unit 1 Appendix I Evaluation (Reference 6). Maximum individual doses are calculated separately for: (1) noble gases in gaseous effluents, (2) particulates, iodines, and tritium in gaseous effluents; and, (3) liquid effluents. Maximum consumption and use factors for various pathways from Table E-5 of the PNPS ODCM are used for calculating the doses to the maximum exposed individual.

Information related to liquid and gaseous effluent releases are summarized Section 2 of this report.

These effluent release data were used as input to computer programs to calculate the resulting doses. The Duke Engineering and Services "YODA"-series of computer programs (Reference 7) was used to compile the dose contributions to the various organs in each age class from major exposure pathways.

4.1 Doses From Noble Gas Releases Gaseous effluent release data presented in Tables 2.2-A, 2.2-B, and 2.2-C from this effluent release report were used as input to the Duke Engineering "YODA" computer programs to calculate radiation doses. These data include gaseous releases from the PNPS main stack, reactor building vent, and turbine building roof exhausters. Meteorological data obtained from the PNPS 220-foot meteorological tower during 2000 were also used as input to the Duke Engineering's "AEOLUS" computer program (Reference 8). This program calculated the atmospheric dispersion and deposition factors used in the "YODA"-series of computer programs to calculate maximum individual doses. These various dispersion (x/Q) and deposition (D/Q) factors are presented in Appendix B.

The maximum individual doses resulting from radioactive noble gases released in gaseous effluents are presented in Table 4.1 according to specific receptor locations. This table includes all noble gas doses for the individual calendar quarters and total calendar year.

It should be noted that doses calculated for the entire year may not equal the sum of the doses for individual quarters. Doses from gaseous effluents are largely dependent on the meteorological conditions during the release period, as prescribed by the NRC in regulatory guides 1.109 and 1.111.

Changes in meteorological conditions throughout the year can affect the amount of dispersion of gaseous effluents and the resulting dose. For example, a release of gaseous effluent during a period when there is little mixing in the air will yield a higher dose than if the same amount of radioactivity is released during a period when atmospheric mixing is high. Quarterly dose values presented in the following tables were calculated using meteorological conditions observed during the applicable quarterly period. In the case of the annual dose values presented, the radionuclide activity from the four quarters were summed for the entire year and doses were calculated using annual-average meteorological conditions.

Noble gases released in gaseous effluents from PNPS during 2000 resulted in a maximum total body dose of 0.13 mrem. The maximum skin dose was 0.98 mrem. Both of these doses occurred to a hypothetical individual, located at the shoreline 0.13 kilometers ENE of the PNPS Reactor Building in the case of total body dose, or 0.08 km N of the reactor building in the case of skin dose. These areas are under control of Entergy Nuclear. Doses to more "realistic" individuals at offsite locations would be lower than doses for these hypothetical site boundary individuals.

4.2 Doses From Gaseous Effluent Releases Gaseous effluent release data presented in Tables 2.2-A, 2.2-B, and 2.2-C from this effluent release report were used as input to the Duke Engineering "YODA" computer programs to calculate radiation doses. These data include gaseous releases from the PNPS main stack, reactor building vent, and turbine building roof exhausters. Meteorological data obtained from the PNPS 220-foot meteorological tower during 2000 were also used as input to the Duke Engineering's "AEOLUS" computer program (Reference 8). This program calculated the atmospheric dispersion and deposition factors used in the "YODA"-series of computer programs to calculate maximum individual doses. These various dispersion (X/Q) and deposition (D/Q) factors are presented in Appendix B.

The maximum individual doses resulting from radioactive particulates, iodines, and tritium released in gaseous effluents are presented in Tables 4.2-A through 4.2-E. These tables cover the individual calendar quarters and the total calendar year, respectively. Doses resulting from releases of noble gases are addressed independently in the PNPS ODCM. Therefore, none of these tables for maximum individual doses include any dose contribution from noble gases. The presentation and analysis of doses resulting from noble gases are addressed in Section 4.1 of this report.

Tables 4.2-A through 4.2-E summarize the maximum total body and organ doses for the adult, teen, child, and infant age classes resulting from the major gaseous exposure pathways. These tables present the dose data according to specific receptor location and the exposure pathways assumed to occur at that location. For example, the second column of the tables presents the information for the hypothetical maximum-exposed at the most restrictive site boundary location, where only inhalation and ground deposition exposure pathways are assumed to occur. Since this is a shoreline location controlled by Entergy, the other pathways of garden vegetable production, milk production, and meat production are assumed not to occur. Doses for other offsite locations not under Entergy control, where other exposure pathways can and do occur, are presented in subsequent columns of the tables, and represent the potential maximum doses to individuals at these locations.

It should be noted that doses calculated for the entire year may not equal the sum of the doses for individual quarters. As was the case with noble gas doses described in Section 4.1, quarterly doses were calculated using meteorological conditions observed during the applicable quarterly period.

Annual dose values are based on the sum of the quarterly noble gas releases, along with the annual average meteorological conditions. A more detailed discussion of the reasons for the differences in annual doses from the summed quarterly doses can be found in Section 4.1.

Radioactivity released in gaseous effluents from PNPS during 2000 resulted in a maximum total body dose (teen age class) of 0.63 mrem. The maximum organ dose (teen age class, thyroid) was 0.79 mrem. Both of these doses occurred to hypothetical individuals at the shoreline 0.1 kilometers NNE of the PNPS Reactor Building, an area under Entergy control. For the more "realistic" individuals at offsite locations, the maximum total body dose was 0.03 mrem (child age class at a location 0.9 kilometers SE from the Reactor Building), while the maximum organ dose was 0.037 mrem (child thyroid at a location 0.9 kilometers SE from the Reactor Building, yielding vegetables).

4.3 Doses From Liauid Effluent Releases Liquid effluent release data presented in Tables 2.3-A and 2.3-B were used as input to the Duke Engineering "YODA" computer programs to calculate radiation doses. The maximum individual doses resulting from radionuclides released in liquid effluents are presented in Tables 4.3-A through 4.3-E. These tables cover the individual calendar quarters and the total calendar year, respectively.

Tables 4.3-A through 4.3-E summarize the maximum total body and organ doses for the adult, teen, and child age classes resulting from the major liquid exposure pathways. NRC Regulatory Guide 1.109 does not recognize the infant age class as being exposed to the liquid effluent pathways.

Therefore, doses for this age class are not included in any of the tables.

It should be noted that doses calculated for the entire year may not equal the sum of the doses for the individual quarters. Doses from liquid effluents are based on the concentration (activity divided by volume) of radionuclides released in the effluent, as prescribed by the NRC in Regulatory Guide 1.109. If a larger proportion of activity is released with a relatively smaller volume of dilution water during a given quarter, the resulting concentration for that quarter will be higher than concentrations from other quarters. This will result in a proportionally higher dose for that quarter. However, when that quarter's activity values are included in the annual sum, and divided by the total annual dilution flow, the resulting dose contribution will be smaller. In such a situation, the annual dose will actually be less than the sum of the individual quarterly doses.

Radioactivity released in liquid effluents from PNPS during 2000 resulted in a maximum total body dose (child age class) of 0.0103 mrem. The maximum organ dose (child age class, bone) was 0.0578 mrem.

5.0 POPULATION AND AVERAGE INDIVIDUAL DOSES Neither the PNPS Technical Specifications nor the ODCM contain limits related to population doses.

However, NRC Regulatory Guide 1.21 (Reference 1) recommends calculation of population and average individual doses to the total body as part of the overall assessment of radiological impact on man.

The population dose is the collective sum of doses received by the entire population residing within 50 miles of PNPS. For example, the average individual receives about 300 to 400 mrem (0.3 to 0.4 rem) per year from cosmic radiation and naturally-occurring radionuclides in the air, soil, water, and food. Assuming each person in the population of 4.18 million people living within 50 miles of PNPS received a dose of 350 mrem (0.35 rem) from such natural radiation exposure, the population total body dose would be estimated to be:

0.35 rem/person

• 4.18 million people = 1.46 million person-rem Total body doses to the entire population within 50 miles of Pilgrim Station resulting from radionuclides in effluents released offsite were calculated using the population distribution based on 1980 census data.

These cumulative population doses were also calculated using methods presented in the PNPS ODCM, NRC Regulatory Guide 1.109, NRC Regulatory Guide 1.111, and the PNPS Appendix I Evaluation. Population doses were calculated separately for gaseous and liquid effluents, and are presented in Tables 5.1-A and 5.2-A , respectively. Unlike the ODCM effluent controls addressing doses to maximum exposed individuals resulting from the three types of releases addressed in Section 4 of this report, population doses for gaseous effluents combine the dose contributions from noble gases along with those from radioactive particulates, iodines, and tritium. Also, in the case of the population doses, average consumption and use factors for various pathways from Table E-4 of the PNPS ODCM were assumed, rather than the maximum use factors assumed for the maximum exposed individual.

Information related to liquid and gaseous effluent releases, as summarized in Section 2 of this report, were used as input to computer programs to calculate the resulting total body doses. The Duke Engineering "YODA"-series of computer programs was used to compile the dose contributions to the total body in each age class from major exposure pathways.

In addition to the population total body doses, doses to an average individual in the population were calculated. These average total body doses were estimated by dividing the total population dose (person-rem) by the total population of 4.18 million people within 50 miles of PNPS. The average individual doses, in mrem, are presented for gaseous and liquid effluents in Tables 5.1-B and 5.2-C, respectively.

37

5.1 Doses From Gaseous Effluent Releases Population total body doses (person-rem) resulting from releases of radionuclides in gaseous effluents are presented in Table 5.1-A. These population doses represent the collective sum of doses received by the entire population living within 50 mile of PNPS. This table includes the doses for the four calendar quarters and entire year resulting from the various gaseous exposure pathways.

The corresponding average individual total body doses (mrem) are presented in Table 5.1-B.

Radioactivity released in gaseous effluents from PNPS during 2000 resulted in a cumulative population total body dose of 0.58 person-rem. The corresponding average individual total body dose was 0.00014 mrem.

Again, it should be noted that the calculated doses for the entire year may be different from the sum of the individual four quarters. This difference is due to the methods and equations used to calculate dose from gaseous effluents, as prescribed by the NRC in Regulatory Guide 1.109. A more detailed discussion of the reasons for the differences can be found in Sections 4.1 and 4.2, in the discussion of maximum individual doses from gaseous effluent releases.

5.2 Doses from Liquid Effluent Releases Population total body doses (person-rem) resulting from releases of radionuclides in liquid effluents are presented in Table 5.2-A. These population doses represent the collective sum of doses received by the entire population living within 50 mile of PNPS. This table includes the doses for the four calendar quarters and entire year resulting from the various liquid exposure pathways. The corresponding average individual total body doses (mrem) are presented in Table 5.2-B.

Radioactivity released in liquid effluents from PNPS during 2000 resulted in a cumulative population total body dose of 0.102 person-rem. The corresponding average individual total body dose was 0.000025 mrem.

Again, it should be noted that the calculated doses for the entire year may be different from the sum of the individual four quarters. This difference is due to the methods and equations used to calculate dose from liquid effluents, as prescribed by the NRC in Regulatory Guide 1.109. A more detailed discussion of the reasons for the differences can be found in Section 4.3, in the discussion of maximum individual doses from liquid effluent releases.

6.0 OFFSITE AMBIENT RADIATION MEASUREMENTS The PNPS ODCM does not contain control limits related specifically to offsite ambient radiation exposure. However, Regulatory Guide 1.21 (Reference 1) recommends calculation of ambient radiation exposure as part of the overall assessment of radiological impact on man.

Thermoluminescent dosimeters (TLDs) are located at 83 sites beyond the boundary of the PNPS restricted/protected area. A number of these TLDs are located within the site boundary, on Entergy property in close proximity to the station proper. The TLDs are collected on a quarterly basis and used to calculate the ambient radiation exposure in milliRoentgen (mR) over the exposure period.

These TLDs are grouped into four zones of increasing distance from the station. Average exposure values for each of these zones were calculated for each calendar quarter and the total year. The average exposure values (mR) for the four zones are presented in Table 6.0.

In addition to responding to ambient radiation exposure, TLDs will also record radiation resulting from noble gases (plume and immersion exposure), particulate materials deposited on the ground, cosmic rays from outer space, and from naturally-occurring radioactivity in the soil and air. Typically, the exposure from cosmic rays and other natural radioactivity components is about 40 to 70 mR/year. As calculated in Sections 4.1 and 4.2 of this report, the ambient radiation component of doses from PNPS effluent emissions are below 1 mrem/yr and would not be discernible above the natural radiation exposure levels.

The major source of ambient radiation exposure from PNPS results from high energy gamma rays emitted from nitrogen-16 (N-16) contained in steam flowing through the turbine. Although the N-16 is enclosed in the process lines and turbine and is not released into the environment, the ambient radiation exposure and sky shine from this contained source accounts for the majority of the radiation dose, especially in close proximity to the station. Other sources of ambient radiation exposure include radiation emitted from contained radioactive materials and/or radwaste at the facility. Despite these sources of ambient radiation exposure at PNPS, increases in exposure from ambient radiation are typically not observable above background radiation levels at locations beyond Entergy controlled property.

The average exposure values presented in Table 6.0 appear to indicate an elevation in ambient exposures in Zone 1, those TLDs within 2 miles of PNPS. Most of this apparent elevation is due to increases in exposure levels measured at TLD locations on Entergy property in close proximity to the station proper. For example, the annual exposure at TLD location OA, located at the Overlook Area near the PNPS Health Club (I&S Building), was 584 mR for the entire year. This location is immediately adjacent to the station proper and overlooks the turbine building, therefore receiving the highest direct ambient and sky shine exposure. When the near-site TLDs (those located within 0.6 km of the Reactor Building) are removed from the calculation of averages, the mean annual exposure in Zone 1 falls from 94.4 +/- 84.6 mR/yr to 62.8 +/- 6.5 mR/yr. Such a corrected dose is not statistically different from the Zone 4 average of 61.0 +/- 7.9 mR/yr.

Although the annual exposure at TLD location OA was 523 mR above the average Zone 4 exposure rate, this area is not continuously occupied by members of the general public. When adjusted for such occupancy, a hypothetical member of the public who was at this location for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per year would only receive an incremental dose of 2.4 mrem over natural background radiation levels. At the nearest residence 0.80 kilometers (0.5 miles) southeast of the PNPS Reactor Building, the annual exposure was calculated as being 60.0 +/- 5.1 mR, which compares quite well to the Zone 4 annual average of 61.0 +/- 7.9 mR.

42

It must be emphasized that the projected ambient exposures discussed on the previous page are calculated to occur to a maximum-exposed hypothetical individual. Even though conservative assumptions are made in the projection of these dose consequences, all of the projected doses are well below the NRC dose limit of 100 mrem/yr specified in 10CFR20.1301, as well as the EPA dose limit of 25 mrem/yr specified in 40CFR190. Both of these limits are to be applied to real members of the general public, so the fact that the dose to the hypothetical maximum-exposed individual is within the limits ensures that any dose received by a real member of the public would be smaller and well within any applicable limit.

In 1994, Pilgrim Station opened the old training facility (I&S Building) overlooking the plant as a health club for its employees. This site is immediately adjacent to the protected area boundary near monitoring location OA and receives appreciable amounts of direct ambient and sky shine exposure from the turbine building. Although most personnel using this facility are employees of Entergy, they are considered to be members of the public. Due to their extended presence in the facility (500 hr/yr, assuming utilization of the facility for 2 hr/day, 5 days a week, for 50 weeks/yr), these personnel represent the most conservative case in regards to ambient radiation exposure to a member of the public. Their annual incremental radiation dose above background during 1999 is estimated as being about 10 mrem, based on the average exposure measured by three TLDs in the building.

The exposures measured by these three TLDs located in the health club would also include any increase in ambient radiation resulting from noble gases and/or particulate activity deposited on the ground from gaseous releases. However, they would not indicate any internal dose received by these contractor personnel from inhalation of small amounts of PNPS-related radioactivity contained in the air. An environmental air sampler located immediately adjacent to the health club did not indicate any PNPS-related activity during 2000. Dose calculations performed in the same manner as those outlined in Section 4.2 yielded a projected total body dose to the maximum-exposed individual (500 hr/yr exposure) of about 0.002 mrem, resulting from inhalation.

Again, it must be emphasized that this exposure was received by personnel who are employees of Entergy, working in a facility on property under the ownership and control of Entergy. Since this exposure was received within the owner-controlled area, it is not used for comparison to the annual dose limit of 25 mrem/yr specified in 40CFR190. This regulation expressly applies to areas at or beyond the owner-controlled property, and is not applicable in this situation. As stated earlier, TLDs at and beyond the site boundary do not indicate elevated ambient radiation levels resulting from the operation of Pilgrim Station.

Although some of the TLDs in close proximity to PNPS indicate increases in exposure levels from ambient radiation, such increases are localized to areas under Entergy control. For members of the general public who are not employed or contracted with Entergy and are accessing Entergy controlled areas (e.g., Shorefront Recreation Area, Health Club, parking lots, etc.), such increases in dose from ambient radiation exposure are estimated as being less than 3 mrem/year.

7.0 PERCENT OF ODCM EFFLUENT CONTROL LIMITS The PNPS ODCM contains dose and concentration limits for radioactive effluents. In addition, the effluent controls specified ensure that radioactive releases are maintained as low as reasonably achievable. The percentage of the PNPS ODCM Control limit values were determined from doses calculated in Section 4, the effluent releases summarized in Section 2, and the ODCM Control limits/objectives listed in Tables 7.1 and 7.2.

The percent of applicable control limit values are provided to supplement the information provided in the Section 2 of this report. The format for the percent of applicable limits is modified from that prescribed in Regulatory Guide 1.21 (Reference 1) to accommodate the Radioactive Effluents Technical Specifications (RETS) which became effective March 01, 1986. The percentages have been grouped according to whether the releases were via liquid or gaseous effluent pathways.

7.1 Gaseous Effluent Releases Dose-based effluent controls related to exposures arising from gaseous effluent releases are presented in Table 7.1. The maximum quarterly air doses and annual whole body doses listed in Table 4.1 were used to calculate the percentage values shown in Table 7.1. All doses resulting from noble gas exposure were a small percentage of the applicable effluent control.

Organ dose limits for the maximum-exposed individual from radioactive particulates, iodines, and tritium from the PNPS ODCM are also shown in Table 7.1. The maximum quarterly and annual organ doses from Tables 4.2-A through 4.2-E were used to calculate the percentages shown in Table 7.1.

The resulting organ doses from Pilgrim Station's gaseous releases during 2000 were a small percentage of the corresponding effluent control.

7.2 Liquid Effluent Releases Liquid effluent concentration limits and dose objectives from the PNPS ODCM are shown in Table 7.2. The quarterly average concentrations from Table 2.3-A were used to calculate the percent concentration limits. The maximum quarterly and annual whole body and organ doses from Tables 4.3-A through 4.3-E were used to calculate the percentages shown in Table 7.2. The resulting concentration and doses from Pilgrim Station's liquid releases during 2000 were a very small percentage of the corresponding effluent control.

8.0 RADIOACTIVE WASTE DISPOSAL DATA Radioactive wastes which were shipped offsite for processing and disposal during the reporting period are described in Table 8.0, in the standard NRC Regulatory Guide 1.21 format.

The total quantity of radioactivity in Curies and the total volume in cubic meters are summarized in Table 3 for the following waste categories:

• Spent resins, filter sludges, and evaporator bottoms;

• Dry compressible wastes, contaminated equipment, etc.;

0 Irradiated components, control rods, etc.; and,

• Other.

During the reporting period approximately 213 cubic meters of spent resins, filter sludges, etc.,

containing a total activity of about 1590 Curies were shipped from PNPS for processing and disposal.

Dry compressible wastes and contaminated equipment shipped during the period totaled 738 cubic meters and contained 0.925 Curies of radioactivity. No irradiated components were shipped during the reporting period. No shipments of irradiated fuel were made during the reporting period.

Estimates of major radionuclides, those comprising greater than 1% of the total activity in each waste category shipped, are listed in Table 8.0. Twenty-seven shipments to Barnwell, SC (Chem Nuclear Systems, Inc.), 20 shipments to Oak Ridge, TN (GTS Duratek, ATG Catalytic), 8 shipments to Erwin, TN (Studsvik), and 4 shipments to Clive, UT (Envirocare) were made during the reporting period.

APPENDIX D CORRECTIONS TO 1999 GASEOUS EFFLUENT DATA During review of several years of past analytical results for strontium-89 (Sr-89) and strontium-90 (Sr-90) releases in gaseous effluents, an error was identified in the results provided for the fourth quarter of 1999. The error involved an incorrect sample collection time used for decay-correcting the analytical results, resulting in an 86% increase in the activity value for Sr-89. Since no Sr-90 was detected during the period, there was no impact on the results for this nuclide. No other nuclides were affected by this error.

An analysis was performed to assess the impact of the erroneous Sr-89 value used in previous dose assessments. Since Sr-89 accounted for only a minor portion of the total activity in gaseous effluent during the period, its contribution to the maximum organ dose was less than 1% of the value of 1.01 E-01 mrem reported for the fourth quarter of 1999.

Revised tables showing the updated values for gaseous effluent releases are attached. A vertical bar in the right margin of each page indicates the updated section.
