Data recovery for the entire annual period was about 67%for the 33-ft level, and 68% for the 220-ft level of the tower. These data recovery values are well below the NRC's recommended annual recovery goal of 90%. Steps have been taken to perform backups of the database computer, as well as performing qualitative data screening on a weekly basis to identify malfunctioning sensors and facilitate more timely repairs. A detailed engineering design plan is being implemented to upgrade meteorological instrumentation to increase reliability and data recovery.19 | Data recovery for the entire annual period was about 67%for the 33-ft level, and 68% for the 220-ft level of the tower.

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 might not equal the sum of the doses for the individual quarters. | 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 might 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. | 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.

This will result in a proportionally higher dose for that quarter. However, when that quarters 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.Since there were no discharges of liquid effluents containing radioactivity, there were no dose consequences resulting from such release, and all resulting doses were zero.28 Table 4.3-A Maximum Individual Organ Doses -- mrem From Liquid Release Period: Jan-Mar 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 0.OOE+00 0.OOE+00 GI-LLI O.OOE+00 0.OOE+00 O.OOE+00 Kidney 0.OOE+00 0.OOE+00 0.OOE+00 Liver 0.OOE+00 0.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 0.OOE+00 Thyroid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 0.OOE+00 0.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during the entire year.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.29 Table 4.3-B Maximum Individual Organ Doses -- mrem From Liquid Release Period: Apr-Jun 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI O.OOE+00 O.OOE+00 O.OOE+00 Kidne O.OOE+00 0.OOE+00 O.OOE+00 Liver 0.OOE+00 O.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 O.OOE+00 Thyroid 0.OOE+00 O.OOE+00 0.OOE+00 T.Body 0.OOE+00 O.OOE+00 0.OOE+00 30 Table 4.3-C Maximum Individual Organ Doses -- mrem From Liquid Release Period: Jul-Sep 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem Organ Adult Teen Child Bone 0.OOE+00 O.OOE+00 0.OOE+00 GI-LLI 0.00E+00 O.OOE+00 O.OOE+00 Kidney O.OOE+00 O.OOE+00 O.OOE+00 Liver 0.OOE+00 0.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 0.OOE+00 Thyroid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 0.OOE+00 0.OOE+00 31 Table 4.3-D Maximum Individual Organ Doses -- mrem From Liquid Release Period: Oct-Dec 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI O.OOE+00 O.OOE+00 O.OOE+00 0Kidney 0 .OOE+00 0.OOE+00 0.OOE+00 Liver O.OOE+00 0.OOE+00 0.OOE+00 Lung0.00E+00 0.OOE+00 0.OOE+00 Throid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 O.OOE+00 0.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during these months.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.32 Table 4.3-E Maximum Individual Organ Doses -- mrern From Liquid Release Period: Jan-Dec 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI 0.OOE+00 O.OOE+00 O.OOE+00 Kidney 0.OOE+00 O.OOE+00 O.OOE+00 Liver 0.OOE+00 O.OOE+00 0.OOE+00 Lung O.OOE+00 O.OOE+00 0.OOE+00 Thyroid 0.OOE+00 O.OOE+00 O.OOE+00 T.Body O.OOE+00 O.OOE+00 O.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during the entire year.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.33 | This will result in a proportionally higher dose for that quarter.

: 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 5.0.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. | : 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.

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 5.0 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 550 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. | 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 5.0 appear to indicate an elevation in ambient exposures in Zone 1, those TLDs within 2 miles of PNPS.

SUMMARY
PILGRIM NUCLEAR POWER STATION RADIOACTIVE EFFLUENT AND WASTE DISPOSAL REPORT INCLUDING METEOROLOGICAL DATA JANUARY 01 THROUGH DECEMBER 31, 2005 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, 2005. 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".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 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 133 Curies. Releases of radioactive iodines and particulates with half-life of greater than 8 days totaled 0.011 Curies, and tritium releases totaled 445 Curies. No gross alpha radioactivity was detected in gaseous effluents.
Noble gases released in gaseous effluents resulted in a maximum total body dose of 0.075 mrem, with a corresponding skin dose of 1.6 mrem. The release of radioactivity in gaseous effluents from PNPS during 2005 resulted in a total body dose to the maximum-exposed hypothetical individual of about 2.9 mrem from radioactive particulates, lodines, and tritium. The maximum hypothetical dose to any organ from radioactive particulates, iodines, and tritium was about 3.2 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 3.0 mrem.The maximum individual doses from gaseous radioactive effluents were compared to the applicable ODCM dose limits. Noble gas doses were less than 12% of the corresponding 10CFR50 dose objectives.
Maximum doses resulting from releases of particulates, iodines, and tritium in gaseous effluents were less than 22% of corresponding 1 OCFR50 objectives.
5 LIQUID EFFLUENTS Liquid radioactive releases for the reporting period are quantified in Tables 2.3-A and 2.3-B. No liquid effluents containing radioactivity were discharged during calendar year 2005.METEOROLOGICAL DATA Meteorological joint frequency distributions are listed in Appendix A. During the course of 2005, numerous problems were encountered with meteorological sensors and translator card electronics.
Data recovery for the entire annual period was about 67% for the 33-ft level, and 68% for the 220-ft level of the tower. The predominant wind direction was from the south-southwest, which occurred approximately 14% of the time during the reporting period. The predominant stability class was Class D, which occurred about 37% 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 elevation in ambient radiation exposure on Entergy property in close proximity to the station, when compared to background levels in the region. This elevation is due to nitrogen-16 contained within the plant steam system, as opposed to radioactive effluent released from the plant. The dose to the maximum-exposed member of the National Guard, who are considered members of the public even though they are within the owner-controlled area, was estimated as being about 19 mrem during 2005. There was no measurable increase during 2005 in ambient radiation measurements at the location of the nearest resident to PNPS.COMBINED DOSE IMPACT The collective total body dose to a maximum-exposed hypothetical member of the public from radioactive gases, liquids, and ambient radiation exposure resulting from PNPS operation during 2005 was calculated as being 5.1 mrem. This amount is less than 2% 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 40CFR190.
Both of these limits are to be applied to real members of the general public, so the fact that the dose to the hvyothetical 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.6 RADIOACTIVE SOLID WASTE DISPOSAL Solid radioactive wastes shipped offsite for processing and disposal during the reporting period are described in Table 7.0. Approximately 539 cubic meters of solid waste, containing 1785 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 2005, there was no significant radiological impact on the general public from PNPS operation.
7 2.0 RADIOACTIVE EFFLUENT DATA Radioactive gaseous and liquid releases for the reporting period are given in the standard format presented in Tables 1A, 11B, 1C, 2A, 2B, and Supplemental Information table from NRC Regulatory Guide 1.21 (Reference
- 1) format.2.1 Sunolemental 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: 133 Ci, 4.21 igCi/sec* Particulates and iodines with 0.01 08 Ci, 0.000341 p.CVsec half-life greater than 8 days* Tritium: 445 Ci, 14.1 gCVsec Effluent releases from the main stack are detailed in Table 2.2-B. The main stack is 335 feet tall, and represents an elevated release point with a total 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 include 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, all of these release points are considered to be mixed-mode/ground level release points.8 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. There were no discharges of liquid effluents containing radioactivity during the calendar year of 2005. Total releases for the various categories of radionuclides, as well as their corresponding mean concentrations, can be summarized as follows:* Total Effluent Volume:* Total Dilution Volume: 0 Liters 0 Liters* Fission/Activation products: 0 Ci, 0 gCi/mL.Tritium: O Ci, 0 pCimL* Dissolved/entrained noble gases: 0 Ci, 0 gCVmL 9 Table 2.1 Pilgrim Nuclear Power Station Effluent and Waste Disposal Report Supplemental Information January-December 2005 FACILITY:

During the course of 2005, numerous problems were encountered with meteorological sensors and translator card electronics.
Data recovery for the entire annual period was about 67%for the 33-ft level, and 68% for the 220-ft level of the tower. These data recovery values are well below the NRC's recommended annual recovery goal of 90%. Steps have been taken to perform backups of the database computer, as well as performing qualitative data screening on a weekly basis to identify malfunctioning sensors and facilitate more timely repairs. A detailed engineering design plan is being implemented to upgrade meteorological instrumentation to increase reliability and data recovery.19 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 2), NRC Regulatory Guide 1.109 (Reference 3), NRC Regulatory Guide 1.111 (Reference 4), and the Pilgrim Station Unit 1 Appendix I Evaluation (Reference 5). 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. PNPS ODCM methodologies were used to calculate 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 a dose assessment computer program 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 the 10-year period from 1994 through 2003 were used as input to the uAEOWS-T3 computer program (Reference 6). This program was used to calculate the annual average atmospheric dispersion and deposition factors used in the dose assessment computer program to calculate maximum individual doses.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.Noble gases released in gaseous effluents from PNPS during 2005 resulted in a maximum total body dose of 0.075 mrem. The maximum skin dose was 1.6 mrem. Both of these doses occurred to a hypothetical individual, located at the shoreline approximately 0.10 kilometers NNE of the PNPS Reactor Building.
These areas are under control of Entergy Nuclear. For the more "realistic" individuals at offsite locations, the maximum total body dose was 0.0041 mrem (nearest residence, 0.80 kilometers ESE from the Reactor Building), while the maximum skin dose was 0.023 mrem (nearest residence, 0.80 kilometers ESE from the Reactor Building).

Meteorological data obtained from the PNPS 220-foot meteorological tower during the 10-year period from 1994 through 2003 were used as input to the "AEOLUS-3" computer program (Reference 6). This program was used to calculate the annual average atmospheric dispersion and deposition factors used in the dose assessment computer program to calculate maximum individual doses.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.
Radioactivity released in gaseous effluents from PNPS during 2005 resulted in a maximum total body dose (teen age class) of 2.9 mrem. The maximum organ dose (teen age class, thyroid) was 3.2 mrem. Both of these doses occurred to hvoothetical individuals at the shoreline 0.10 kilometers NNE of the PNPS Reactor Building, an area under Entergy control. For the more "realistic M individuals at offsite locations, the maximum total body dose was 0.16 mrem (child age class at nearest garden location, 0.87 kilometers SE from the Reactor Building), while the maximum organ dose was 0.17 mrem (child thyroid at nearest garden location, 0.87 kilometers SE from the Reactor Building, yielding vegetables).

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 might 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 quarters 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.Since there were no discharges of liquid effluents containing radioactivity, there were no dose consequences resulting from such release, and all resulting doses were zero.28 Table 4.3-A Maximum Individual Organ Doses -- mrem From Liquid Release Period: Jan-Mar 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 0.OOE+00 0.OOE+00 GI-LLI O.OOE+00 0.OOE+00 O.OOE+00 Kidney 0.OOE+00 0.OOE+00 0.OOE+00 Liver 0.OOE+00 0.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 0.OOE+00 Thyroid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 0.OOE+00 0.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during the entire year.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.29 Table 4.3-B Maximum Individual Organ Doses -- mrem From Liquid Release Period: Apr-Jun 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI O.OOE+00 O.OOE+00 O.OOE+00 Kidne O.OOE+00 0.OOE+00 O.OOE+00 Liver 0.OOE+00 O.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 O.OOE+00 Thyroid 0.OOE+00 O.OOE+00 0.OOE+00 T.Body 0.OOE+00 O.OOE+00 0.OOE+00 30 Table 4.3-C Maximum Individual Organ Doses -- mrem From Liquid Release Period: Jul-Sep 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem Organ Adult Teen Child Bone 0.OOE+00 O.OOE+00 0.OOE+00 GI-LLI 0.00E+00 O.OOE+00 O.OOE+00 Kidney O.OOE+00 O.OOE+00 O.OOE+00 Liver 0.OOE+00 0.OOE+00 0.OOE+00 Lung 0.OOE+00 0.OOE+00 0.OOE+00 Thyroid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 0.OOE+00 0.OOE+00 31 Table 4.3-D Maximum Individual Organ Doses -- mrem From Liquid Release Period: Oct-Dec 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI O.OOE+00 O.OOE+00 O.OOE+00 0Kidney 0 .OOE+00 0.OOE+00 0.OOE+00 Liver O.OOE+00 0.OOE+00 0.OOE+00 Lung0.00E+00 0.OOE+00 0.OOE+00 Throid 0.OOE+00 0.OOE+00 0.OOE+00 T.Body 0.OOE+00 O.OOE+00 0.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during these months.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.32 Table 4.3-E Maximum Individual Organ Doses -- mrern From Liquid Release Period: Jan-Dec 2005 No Liquid Effluent Discharges Occurred During This Period Age Class Organ Dose -mrem *Organ Adult Teen Child Bone O.OOE+00 O.OOE+00 O.OOE+00 GI-LLI 0.OOE+00 O.OOE+00 O.OOE+00 Kidney 0.OOE+00 O.OOE+00 O.OOE+00 Liver 0.OOE+00 O.OOE+00 0.OOE+00 Lung O.OOE+00 O.OOE+00 0.OOE+00 Thyroid 0.OOE+00 O.OOE+00 O.OOE+00 T.Body O.OOE+00 O.OOE+00 O.OOE+00* These doses are conservative since the same usage factor was applied for each quarter.In reality, it is unlikely that anyone would be swimming or boating during the entire year.However, the resulting dose is considerably lower than those from other pathways and does not contribute much to the total dose.33 5.0 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 5.0.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 5.0 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 550 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 95.1 +/- 81.4 mR/yr to 65.2 i 11.4 mR/yr. Such a corrected dose is not statistically different from the Zone 4 average of 63.8 +/- 12.3 mR/yr, and is indicative of natural background radiation.
Although the annual exposure at TLD location OA was 486 mR above the average Zone 4 exposure, members of the general public do not continuously occupy this area. 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 2.2 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 66.1 +/- 11.1 mR (based on continuous occupancy at this location), which compares quite well to the Zone 4 annual average background radiation level of 63.8 +/- 12.3 mR.34 It must be emphasized that the projected ambient exposures discussed on the previous page are calculated to occur to a maximum-exposed hvoothetical 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 within the PNPS owner controlled area. Their annual incremental radiation dose above background during 2005 is estimated as being about 6.1 mrem, based on the average exposure measured by the TLD in the building.The exposures measured by the TLD 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 personnel in this facility 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 2005. Dose calculations performed in the same manner as those outlined in Section 4.2 for airborne effluent releases yielded a projected total body dose to the maximum-exposed individual (500 hr/yr exposure) of about 0.011 mrem, resulting from inhalation.
In response to the September 11, 2001 terrorism event, access to areas in the immediate vicinity of Pilgrim Station by members of the general public has been discontinued.
A number of National Guard troops have been posted at Pilgrim Station to patrol the owner-controlled areas beyond the protected area. However, since these individuals are not employees of Pilgrim Station, they are considered to be members of the public for dose assessment purposes.
Considering that their location is not fixed and they are patrolling areas within the site boundary, their annual exposure was estimated based on the average of those TLDs between the protected area fence and site boundary.The maximum dose received by a member of the National Guard is estimated to be about 18.9 mrem. Inhalation doses for National Guard troops, calculated in the same manner as that described above, were calculated at about 0.048 mrem.Again, it must be emphasized that the above-described exposures were received by personnel who are employees or contractors of Entergy, accessing areas or facilities 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 mremryr 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., parking lots, etc.), such increases in dose from ambient radiation exposure are estimated as being less than 2.2 mrem/year.

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 6.1 and 6.2.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) that became effective March 01, 1986. The percentages have been grouped according to whether the releases were via liquid or gaseous effluent pathways.6.1 Gaseous Effluent Releases Dose-based effluent controls related to exposures arising from gaseous effluent releases are presented in Table 6.1. 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 6.1. 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 6.1. 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 6.1.The resulting organ doses from Pilgrim Station's gaseous releases during 2005 were a small percentage of the corresponding effluent control.37 Table 6.1 Percent of ODCM Effluent Control Limits for Gaseous Effluent Releases During 2005 A.

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 6.2. Since no discharges of liquid effluent containing radioactivity occurred during 2005, all resulting concentrations, dose consequences, and fractional limits of NRC limits are zero.40 Table 6.2 Percent of ODCM Effluent Control Limits for Liquid Effluent Releases During 2005 A.

- Spent resins, filter sludges, and evaporator bottoms;* Dry activated wastes, contaminated equipment, etc.;* Irradiated components, control rods, etc.; and,* Other.During the reporting period approximately 65.8 cubic meters of spent resins, filter sludges, etc., containing a total activity of about 1,260 Curies were shipped from PNPS for processing and disposal.Dry activated wastes and contaminated equipment shipped during the period totaled 614 cubic meters and contained 3.03 Curies of radioactivity.
One shipment of irradiated components was shipped during the reporting period containing 21.6 cubic meters and 14.0 curies. The "Other" category, made up from "Hi Rad Trash" consisted of 66.4 cubic meters and 6.19 curies. 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 7.0. There were 13 shipments to Oak Ridge, TN (Duratek);
3 shipments to Memphis, TN (RACE); and 12 shipments to Erwin, TN (Studsvik) and 1 shipment to Diversified Scientific Services, Inc.43 Table 7.0 Pilgrim Nuclear Power Station Effluent and Waste Disposal Report Solid Waste and Irradiated Fuel Shipments January-December 2005 A.
