INTRODUCTION 

EXECUTIVE SUMMARY 

PILGRIM NUCLEAR POWER STATION 

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT 

JANUARY 01 THROUGH DECEMBER 31, 2015 

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, 2015. 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". This 

document has been prepared in accordance with the requirements of PNPS Technical 

Specifications section 5.6.3. 

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 1.99 Curies. Releases of 

radioactive iodines and particulates with half-life of greater than 8 days totaled 0.00091 Curies, 

tritium releases totaled 72 Curies, and carbon-14 totaled 7.2 Curies. No gross alpha radioactivity 

was detected in gaseous effluents. 

Noble gases released in gaseous effluents resulted in a maximum total body dose of 0.000074 

mrem, with a corresponding skin dose of 0.00014 mrem. The release of radioactive particulates, 

iodines, tritium, and carbon-14 in gaseous effluents from PNPS during the reporting period resulted 

in a total body dose to the maximum-exposed hypothetical individual of about 0.016 mrem. The 

maximum hypothetical dose to any organ from radioactive particulates, iodines, tritium, and carbon14 was about 0.071 mrem. The maximum, hypothetical total body dose from the combined release 

of all airborne radioactivity in gaseous effluents was 0.016 mrem. 

The maximum individual doses from gaseous radioactive effluents were compared to the 

applicable ODCM dose limits. Noble gas doses were less than 0.0012% of the corresponding 

1 OCFR50 dose objectives. Maximum doses resulting from releases of particulates, iodines, tritium, 

and carbon-14 in gaseous effluents were less than 0.47% of corresponding 10CFR50 objectives. 

Page 5 
LIQUID EFFLUENTS 

Liquid radioactive releases for the reporting period are quantified in Tables 2.3-A and 2.3-8. Seven 

discharges of liquid effluents containing radioactivity occurred during the reporting period. These 

discharges contained 3.6 Curies of tritium, and 0.00066 Curies of fission and activation products. 

The resulting maximum total body dose was 0.000067 mrem, with a corresponding organ dose of 

0.00020 mrem. All doses from liquid discharges were less than 0.0057% of corresponding 

1 OCFR50 objectives. 

METEOROLOGICAL DATA 

Meteorological joint frequency distributions are listed in Appendix A. Data recovery for the entire 

annual period was 78% for the 33-ft and 76% for the 220-ft levels of the tower. 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 A, which occurred about 29% 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 thermolumin_escent 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 public at the PNPS Health Club, even though they are within the 

owner-controlled area, was estimated as~ being about 1.3 mrem during 2015. There was no 

measurable increase during 2015 in ambient radiation measurements at the location of the nearest 

resident 0.8 km southeast of PNPS. 

COMBINED DOSE IMPACT 

The collective total body dose to a maximum-exposed hypothetical member of the public from 

airborne radioactivity, liquid-borne radioactivity, and ambient radiation exposure resulting from 

PNPS operation during 2015 was calculated as being about 0. 79 mrem. This amount is about 

0.2% 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 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 wastes shipped offsite for processing and disposal during the reporting period are 

described in Table 7.0. Approximately 1220 cubic meters of solid waste, containing almost 191 

Curies of radioactivity, were shipped during the reporting period. 

Page 6 
ONSITE GROUNDWATER MONITORING PROGRAM 

In response to the Nuclear Energy Institute Groundwater Protection Initiative, Pilgrim Station 

instituted a groundwater monitoring program during 2007. Four monitoring wells were installed 

onsite during the fourth quarter of 2007, and the first samples were collected in late November 

2007. Additional sampling wells were added in 2010, ·2011, 2012, 2013, and 2014. As of the end 

of 2015, samples are being collected from a total of 23 monitoring wells. Low levels of tritium, a 

radioactive isotope of hydrogen, were detected in several of these onsite wells. No other plantrelated radioactivity was detected in the groundwater samples. The average concentration of 

tritium detected in these onsite monitoring wells during 2015 was well below the voluntary 

communications reporting level established by the EPA Drinking Water Standard of 20,000 pCi/L. 

Although the EPA Standard provides a standard for comparison, no drinking water sources are 

affected by this tritium. The maximum hypothetical dose resulting from tritium in groundwater 

presumed to enter Cape Cod Bay is calculated to be 0.0000000061 mrem/yr. Results of the 

groundwater monitoring program are presented in Appendix B. 

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 2015, 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, 18, 1C, 2A, 28, 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: 1.99 Ci, 0.0630 μCi/sec 

• Iodines and particulates with 0.000905 Ci, 0.0000287 μCi/sec 

half-life greater than 8 days 

• Tritium: 71.9 Ci, 2.28 μCi/sec 

• Carbon-14: 7.18 Ci, 0.228 uCi/sec 

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.?-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. 

Following the revision of Regulatory Guide 1.21 in 2009, the nuclear industry re-assessed their 

gaseous effluent releases in accordance with the new definition of "principal radionuclide". Under 

this new definition, any radionuclide that contributed greater than 1 % of the effluent dose 

calculated to demonstrate compliance with 10CFR50 Appendix I, or contributed more than 1 % of 

the total activity for that type of effluent release, would be classified as a principal radionuclide. 

Although Carbon-14 (C-14) had been exempted from gaseous effluent calculations in the 1970s, 

industry assessments in 2009 revealed that Carbon-14 would qualify as a principal radionuclide. 

Based on this 2009 re-assessment, licensees were required to begin reporting C-14 gaseous 

effluents in the Annual Radioactive Effluent Release Report beginning with calendar-year 2010. 

Carbon-14 releases for 2015 are summarized in Tables 2.2-A through 2.2-C, and the dose 

consequences from C-14 are incorporated into the dose assessments documented in Section 4.2 

of this report. 

Page 8 
Table 3.1-2 of the PNPS ODCM requires that if any of the gaseous effluent monitors are 

inoperable for more than 30-days, such events are to be reported in the Annual Radioactive 

Effluent Release Report with an explanation of why the affected monitor was not returned to 

operable status in a timely manner. There were no instances in 2015 during which an singlechannel effluent monitor was out of service for more than a 30 consecutive day period, or when 

both channels of a dual-channel effluent monitor were out of service at the same time during a 30 

consecutive day period. 

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 seven discharges of liquid effluents containing 

radioactivity 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: 424,000 Liters 

• Total Dilution Volume: 562 billion Liters 

• Fission/Activation products: 0.000659 Ci, 0.00000000000117 μCi/ml 

• Tritium: 3.56 Ci, 0.00000000633 μCi/ml 

• Dissolved/entrained noble gases: 0.00 Ci, 0.00 μCi/ml

3.0 METEOROLOGICAL DATA 

Meteorological data 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: I 

• Stability Class: Class A, 29% 

• 33-ft Wind Direction (from): South-southwest, 13% 

• 33-ft Wind Speed: 3.5-7.5 mph, 56% 

• 220-ft Wind Direction (from): Southwest, 13% 

• 220-ft Wind Speed: 12.5-18.5 mph, 36% 

Joint data recovery for the 33-ft level was 78.2% and for the 220-ft level of the tower was 76.0%, 

neither of which meet the 90% annual data recovery goal specified by the NRC. J;>roblems were 

encountered in the first quarter of the year when the cable supplying power to the aspirator fans on 

the temperature sensors of the 220-ft tower failed, resulting in invaiid delta-temperature readings 

used to determine atmospheric stability class. In December 2015, the main power supply for the 

220-ft tower meteorological dataloggers failed, resulting in the loss of three weeks of data at the 

end of the year. Although a new backup 160-ft tower was constructed in late October-2015, it was 

not put into service until March 2016. 

Page 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 Tabl~ 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 

"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 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 2015 resulted in a maximum total 

body dose of 0.000074 mrem. The maximum skin dose was 0.00014 mrem. Both of these doses 

occurred to a hypothetical individual, assumed to be present 24 hours per day, 365 days per year, 

at the site boundary location yielding the highest dose (0.63 km SSW of the Reactor Building). For 

the more "realistic" individuals at offsite locations, the maximum total body dose was 0.000066 

mrem (nearest residence, 0.86 kilometers WNW from the Reactor Building), while the maximum 

skin dose was 0.00010 mrem (nearest residence, 0.86 kilometers WNW from the Reactor 

Building).

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 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 2005 through 2014 were used as input to the 

NRG XOQDOQ computer program (Reference 7). 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, radioiodines, tritium and 

carbon-14 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. For consistency, all distances listed in the first row of Tables 4.2-A through 4.2,..E 

are measured from the Reactor Building Vent. However, doses at the specific receptor locations 

are calculated based on the actual distances from the applicable release points (PNPS main stack, 

reactor building vent, and turbine building roof exhausters). 

Radioactivity (particulates, radioiodines, tritium, and carbon-14) released in gaseous effluents from 

PNPS during 2015 resulted in a maximum total body dose of 0.016 mrem (child age class at 

nearest meat animal, 3.82 kilometers S from the Reactor Building), while the maximum organ dose 

was 0.071 mrem (child bone at nearest meat animal, 3.82 kilometers S from the Reactor Building). 

Carbon-14 contrif>uted 91% of the child total body dose and >99% of the child bone dose at the 

location of the nearest meat animal.

4.3 Doses From Liquid Effluent Releases 

Liquid effluent release data presented in Tables 2.3-A and 2.3-B were used as input to the dose 

assessment computer program 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 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 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 the , reporting period resulted in a 

maximum total body dose (child age class) of 0.000067 mrem. The maximum organ dose (adult 

age class, Gl-LLI) was 0.00020 mrem.

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 86 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 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 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 (l&S Building), was 178 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 71.3 ± 22.1 mR/yr to 61.4 ± 8.7 mR/yr. Such a corrected dose is not 

statistically different from the Zone 4 average of 57.9 ± 10.2 mR/yr, and is indicative of natural 

background radiation. 

Although the annual exposure at TLD location OA was 120 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 hours per 

year would only receive an incremental dose of 0.55 mrem over natural background radiation 

levels. At the nearest residence 0.8 kilometers (0.5 miles) southeast of the PNPS Reactor 

Building, the annual exposure was calculated as being 57.9 ± 8.0 mR (based on continuous 

occupancy at this location), which compares quite well to the Zone 4 annual average background 

radiation level of 57.9 ± 10.2 mR. Statistically, there is no difference between these two values. 

Page 34 
Pilgrim Station began moving spent fuel to the Independent Spent Fuel Storage Installation (ISFSI) 

located within the protected area immediately west of the PNPS Reactor Building. Three new 

TLDs were installed at the beginning of 2016 to monitor any incremental dose from this facility. 

TLD ISF-1 was located on Rocky Hill Road 0.35 km (0.21 mi) southwest of the reactor building. 

The annual exposure at this location was calculated as being 73.1 ± 9.0 mR (based on continuous 

occupancy at this location), or 15.2 mR above the Zone 4 average of 57.9 mR. However, the area 

is not continuously occupied, and when corrected for an exposure time of 365 hours/year, the 

estimated exposure to a person walking along this section of Rocky Hill Road would be 0.63 

mR/year. 

It must be emphasized that the projected ambient exposures discussed above and 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 1 OCFR20.1301, 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 (l&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 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 2015 is estimated as being about 1.3 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 2015. 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 0.0018 mrem, resulting from inhalation. 

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 mrem/yr specified in 40CFR190. 

This regulation explicitly 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 1.3 mrem/year.

6.0 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 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 2015 were a 

small percentage of the corresponding effluent control.

6.2 Liquid Effluent Releases 

Liquid effluent concentration limits and dose objectives from the PNPS ODCM are shown in Table 

6.2. 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 6.2. The resulting 

concentrations, as well as organ and total body doses from Pilgrim Station's liquid releases during 

the reporting period were a small percentage of the corresponding effluent controls.

7.0 RADIOACTIVE WASTE DISPOSAL DATA 

Radioactive wastes that were shipped offsite for processing and disposal during the reporting 

period are described in Table 7.0, 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 7.0 for the following waste categories: 

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 111.0 cubic meters of spent resins, filter sludges, etc., 

containing a total activity of about 182.0 Curies were shipped from PNPS for processing and 

disposal. Dry activated wastes and contaminated equipment shipped during the period totaled 

1110.0 cubic meters and contained 8. 77 Curies of radioactivity. There were no shipments of 

irradiated components during the reporting period. There were no shipments of "Other wastes" 

during the reporting period. There were no shipments of irradiated fuel 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 w13re 42 shipments to Energy Solutions' 

Bear Creek Facility in Oak Ridge, TN; 5 shipments to Energy Solutions Erwin Resin Solutions' 

Facility in Erwin, TN.; and 1 shipment to Energy Solutions Clive Disposal Site in Clive Utah.

Results of Onsite Groundwater Monitoring Program 

In response to the Nuclear Energy Institute (NEI) Groundwater Protection Initiative, Pilgrim Station 

instituted a groundwater monitoring program during 2007. Four monitoring wells were installed 

inside the protected area fence during the fourth quarter of 2007. The fir5t samples were collected 

in November 2007. Since these are onsite wells, they are not considered part of the Radiological 

Environmental Monitoring Program (REMP), and data from these wells are being reported in the 

annual Radiological Effluent Release Report. Two pre-existing wells were incorporated into the 

groundwater monitoring program in early 2008. Additional wells were added to the program in 

2010 (12 wells), 2011 (2 wells), 2012 (1 well), 2013 (3 wells), and 2014 (1 well). A total of 23 wells 

are being sampled on a routine basis. 

In addition to sampling the onsite monitoring wells, samples of surface water are collected from two 

locations in the PNPS Intake Canal. These locations are along the shoreline in the same direction 

as the groundwater flow gradient. 

All samples collected are analyzed for tritium, a radioactive isotope of hydrogen, and also for 

gamma emitting radionuclides. In accordance with industry practice established under the NEI 

initiative, lower limits of detection (LLDs) used for analysis of REMP samples were used when 

assessing these samples for the presence of radioactivity. Low levels of tritium were detected in 

many of the. onsite wells. Although gamma spectroscopy indicated the presence of naturallyoccurring radioactivity, such as Potassium-40 and radon daughters from the uranium/thorium decay 

chains, there was no indication of any plant-related radioactivity in the groundwater samples, other 

than tritium. Such levels of natural radioactivity are expected as these radionuclides are dissolved 

into the groundwater from the rocks and soil. The fact that these low levels of naturally-occurring 

radioactivity can be detected demonstrates the ability of the gamma spectroscopy analyses to 

detect radioactivity in groundwater. Analyses are also performed for hard-to-detect radionuclides, 

including lron-55, Nickel-63, Strontium-89, and Strontium-90 on a less frequent basis .. These hardto-detect radionuclides were also non-detectable in all of the wells sampled and analyzed during 

2015. 

A summary of the results of the tritium analyses conducted in 2015 are presented in the following 

table. In this table, a value of "NDA < xx" in the columns indicates that no activity was detected in 

the sample when analyzed to thE;i minimum-detectable level following the "<" sign. For example, 

the sample collected from MW20t,on 16-Jan-2015 contained no detectable tritium, and a minimum 

detectable concentration of 369 pCi/L was achieved on that sample. The achieved sensitivity of 

369 pCi/L is well below the required REMP LLD of 3000 pCi/L, and no tritium was detected even 

when counted to this more sensitive level of detection. No plant-related radioactivity (other than 

~ tritium) was detected in any of the monitoring wells, and no tritium or plant-related radioactivity was 

detected in surface water samples collected from the intake canal.

Concentrations of tritium detected in the onsite wells ranged from non-detectable at less than 183 

pCi/L, up to a maximum concentration of 4300 pCi/L. The average concentrations from these 

onsite wells are well below the voluntary communication reporting level of 20,000 pCi/L as 

established by the EPA Drinking Water Standard. Although the EPA Standard provides a baseline 

for comparison, no drinking water sources are affected by this tritium. All of the affected wells are 

onsite, and the general groundwater flow pathway is under Pilgrim Station and out into the salt 

water of Cape Cod Bay. As such, there is no potential to influence any off-site drinking water wells. 

Even if worst-case assumptions were made and the water from monitoring well MW216 (average 

concentration = 2504 pCi/L) was consumed as drinking water for an entire year, the maximum dose 

consequence would be less than 0.22 mrem/yr. In actuality, any dose consequence would be 

much less than this, as any tritium-laden water potentially leaving the site would be diluted into the 

seawater of Cape Cod Bay before being incorporated into any ingestion pathways. No drinking 

water ingestion pathway exists at the Pilgrim Station site. 

Page 71 
Although there are no indications that the groundwater containing detectable tritium is actually 

migrating offsite, a bounding calcula_tion was performed to assess the potential dose impact of 

such a scenario. Based on the tritium concentrations detected during 2015, the annual average 

concentrations of tritium in groundwater in the four monitoring wells most closely adjacent to the 

shoreline (MW204, MW205, MW202, and MW201) were used to estimate potential tritium 

migration into.the intake bay. Hydrological characteristics of the compacted backfill in the vicinity of 

these wells were measured in 2010 and indicate the hydraulic conductivity ranges from 0.002 

cm/sec to about 0.006 cm/sec. When coupled with the hydraulic slope of 0.014 and average 

porosity of 0.3, the flow velocity was calculated as being between 0.08 and 0.23 meters per day. 

Using an assumed horizontal shoreline interface area 236 meters long by 3 meters deep that could 

potentially transmit groundwater into the intake bay, the annual discharge of groundwater would be 

about 12.5 million Liters of water per year. Assuming this volume of 12.5 million liters contained 

the segment-weighted average concentration of 481 pCi/L, the annual discharge of tritium into the 

intake bay under this hypothetical scenario would be 0.00601 Curies. This activity represents less 

than 0.008% of the annual airborne effluent of tritium released from the· reactor building vent (see 

Table 2.2,.C). Such airborne effluents can be washed down to the ground surface during 

precipitation events and infiltrate into the ground, thereby introducing tritium into the groundwater. 

In the hypothetical scenario described above, the 0.00601 Curies of tritium entering the intake bay 

would be further diluted into the circulating water flow of the plant. As documented in Table 2.3-A, 

the total volume of circulating water flow during 2015 was 562 billion Liters, yielding an effective 

concentration of tritium in the intake bay of about 0.011 pCi/L. Such a concentration would be well 

below the detection sensitivity of about 450 pCi/L used to analyze water collected from the 

discharge canal as part of the radiological environmental monitoring program (REMP). The 

calculated dose to the maximum-exposed member of the public from such a hypothetical release 

would be 0.0000000061 millirem, resulting from ingestion of tritium incorporated into fish and 

shellfish. Since the tritium would be incorporated into seawater, there is no drinking water 

ingestion pathway in the described scenario. 

The following table lists the hydrological characteristics in the vicinity of each of the monitoring 

wells used to estimate tritium migration. Predicted flow velocities, annual discharge volumes, 

average tritium concentrations, and hypothetical tritium discharges are listed for each shoreline 

segment represented by each monitoring well.

In conclusion, the only radionuclide detected in groundwater during the 2015 monitoring effort that 

is attributable to Pilgrim Station operations is tritium. Although some soil samples near the 

separation in the underground discharge line from the neutralizing sump indicated the presence of 

low-level gamma radioactivity, such activity has not been detected in the groundwater and 

indicates the _radioactivity is immobile and confined to the soil. Even in the case of the three 

reportable events that occurred in 2013 and subsequent sample results in 2015, the total dose 

impact to a maximally-exposed member of the public would have been much less than 1 mrem/yr.
