No new wells were installed, nor were any wells I retired. MW-16 was sampled twelve ( 12) times throughout 2020, two (2) of which were included in the yearly biannual sampling. No adverse effect to the offsite environment has been detected at this time, because all offsite groundwater, I drinking water and surface water samples were <440 pCi/L. See Enclosure 2, Page xvii for additional details. I Onsite Spills: There were no onsite spills > 100 gallons. Decommissioning File Update: There is one (l) item to be added to the site decommissioning files in I accordance with 10CFR50.75(g). Abnormal Liquid Releases: There were no abnormal liquid releases. I Abnormal Gaseous Releases: There was one (1) abnormal gaseous release. Liquid Radwaste Treatment System: The site operated via a shared Liquid Radwaste Treatment System, I even though each Unit has its own ion-exchange vessels. Shared operation allowed either Unit to process liquid waste at the Unit of origin, or at the other Unit. Typically, when Unit 1 or 2 high level liquid waste was processed (e.g., coolant recovery waste) it was performed at Unit 1, because it has a carbon pre-conditioning filter. I Gaseous Radwaste Treatment System: The site operated via a shared Gaseous Radwaste Treatrnen1 System, even though each Unit has its own charcoal delay beds and storage/decay tanks. Shared operation I allowed either Unit to process gaseous waste at the Unit of origin, or at the other Unit. Typically, when Unit 1 or 2 went to a shutdown condition, the gaseous waste was transferred for storage and decay at Unit 2, because Unit 2 has four (4) additional storage tanks. All doses from continuous releases of the Process Vent I (elevated pathway) are assigned to Unit 1. I I I I I I I

I Effluent Monitoring Channels Inoperable >30 Days:There were two (2) Effluent Monitoring Instrumentation Channels not returned to Operable status within 30 days. I ODCM Surveillance Deficiencies: There were three (3) instances of ODCM Surveillance Deficiencies. ODCM Changes: There was one (I) change made to the ODCM. I Meteorological Data Recovery: The Meteorological Data Recovery met the minimum requirement of at-least 90%, as specified in Section 5 of Revision 1 to Regulatory Guide 1.23, Meteorological Monitoring Programs for Nuclear Power Plants. I Carbon-14 Dose Assessment: Carbon-14 dose was calculated using EPRI & RG-1.109 calculation methods and the default ODCM receptor. The highest organ doses were to the bone (child). Details of the I dose assessment due to releases of Carbon-14 in gaseous effluents are provided in Attachment 3 of this report. I I I I I I I I I I

The steady I decreases are due to extended hold-up periods of gas space prior to release. The differences between the units are relative to the outages that occured that year. I Note that in 2019, due to new effluent software, all continuous releases out of the elevated release Process Vent are now assigned to Unit l, even though it is a shared pathway. This accowits for the drastic change in trend values. I The sharp increase in gaseous release activity that occurred from Unit 2 in 2020 was determined to have been the result of the routine degassification of the Unit 2 reactor coolant system that occurred as part of the 2R21 refueling outage. RCS degas activity is conservatively approximated by using the results of samples I taken during startup from the previous Unit 2 outage, and the sample used during 2R2 l contained a high concentration of Argon-41, which accowits for the increase in activity. These releases did not pose any radiation health risk to the public or plant personel, nor did they exceed any NRC regulations or reporting I criteria. 10000.00 I 1000.00 I 100.00 10.00 I 1.00 I

The recent decreases were due to efforts to reduce overall offsite dose. Specifically, discharging liquid radioactive inventory provided the benefit of reduced total offsite dose, due to reduction in evaporative losses from the fuel pools. I Note that beginning in 2019, Beaver Valley no longer adjusts gaseous tritium effluents for background tritium and for evaporation of tritium from Fuel Pool. Excluding these adjustments provides a more conservative total for gaseous tritium released. I I I I

The leak rate was estimated at 1-2 drops per second with an estimated total leak volume of 3-4 gallons. Analysis of the leak I indicated greater than 2000 picocuries per liter of tritium , and the presence of Mn-54, Co-58, Co-60, and Cs-137 above their lower limits of detection. A catch containment was placed underneath the leak, and standing liquids on the concrete below were cleaned up. No I smearable radioactive contamination was present after the clean up, however due to crack being present in the concrete below, it is not certain whether any liquid made contact with the soil underneath. A voluntary communication was made to the Pennsylvania Department of Environmental Protection, Bureau of I Radiation Protection, and the NRC Resident Inspector was also notified of the leak. The leakage did not pose any radiation health risk to the public or plant personnel, nor did it exceed any NRC regulations or reporting criteria. This event is captured in CR-2020-05157, and an action has been written to update the 10CRF50.75(g) files. I I I I I I I I I I

Additional communication for new well resufts was performed on 09/08/10 for those new wells that exceeded 2000 pCi/L.

The permit was originally created using an Excel spreadsheet and was accounted for in the old MIDAS software system, but was never remade in RADEAS. Upon discovery, the permit was generated in RADEAS (U1GB2019-171) and the new activity and dose totals will result in the I following changes to the 2019 ARERR: 1: Page 2, Summation of All Releases, gaseous tritium for the 1st Quarter will increase from 5.50 Ci to 5.51 Ci (0.18% difference). I 2: Page 4, Gaseous Effluents - Elevated Continuous Releases (Unit 1 & 2), gaseous tritium for the 1st Quarter will increase from 0.594 Ci to 0.601 Ci (1 .16% difference) 3: The above change to Page 4, 1st Quarter results will change the total annual value reported in the same table from 0.776 Ci to 0.783 Ci. I It was also noticed that the requirement to provide a brief summary stating that annual dose from the Independent Spent Fuel Storage Installation (ISFSI) was included in the annual report was inadvertantly left out of the 2019 ARERR. This will result in the following change to the 2019 ARERR: I 1: Page 19, Total Dose Commitments and Total Effective Dose Equivalents, the following passage will be added : I While there are minimal gaseous and liquid effluents specifically from the Independent Spent Fuel Storage Installation (ISFSI). there is a contribution from Direct Radiation. The doses listed in this section include the contributions from the ISFSI. I I I I I I I I I

- 1) Unit 1 discharge structure blowdown weir flow transmitter FT-1CW-101-1 and cooling tower blowdown flow I
transmitter FT-1CW-101 Cooling tower biowdown flow transmitter FT-1 CW-1 O1 and discharge structure blowdown wier flow transmitter FT-1 CW-1 O1-1 remained out of service from September 9, 2020 and September 15, 2020, respectively, through the end of the year. I I During calibration work, technicians determined that each transmitter had frayed wires and nonfunctioning sensors which required repairs. Additionally, the replacement parts for the cooling tower blowdown flow transmitter were determined to be obsolete and unobtainable. Cooling tower blowdown flow transmitter 2CWS-FT101 was used as the 1st Alternate method for calculating the dilution rate in regards to liquid waste discharges, however on December 2 , 2020, 2CWS-FT101 failed off I scale high, and was not returned to service through the end of the year. Dilution rate can be calulated during actual discharges by the completion of 1 MSP-31.06-1, F-CW101-1 Outfall Structure Discharge Flow Calibration, ever four hours.
- 2) Unit 2 effluent radiation monitors 2HVS-RQ1098/C/D Containment ventilation gaseous effluent radiation montiors 2HVS-RQ109B/C/D remained out of service from August 17, 2020 through the end of the year. The monitors were removed from service for performance of 2MSP-43.33-I, Elevated Release Gas Radiation Monitor 2HVS-RQl109B, C, and D Calibration, during which the velocity probe was sent out to the I
vendor for calibration. The probe was lost during shipping, and a new probe was ordered form the vendor, with the monitors remaining out of service until the new part is recieved. Compensatory grab samples are being taken in accordance with ODCM requirements. I I I I I I 1-1

This was calcu1ated by comparing offsite TLD exposure at the ODCM controlling location (0.8 miles NW; Midland, PA) to n.o exposure at the I REMP conti:ol location 16.5 miles SSW; Weirton, Compliance to 100 mrem Limit of 18 CFR 20.1301 For T~tal Effective Dose Equivalent I Pursuant to 10 CFR 20.1301 (a)(1 ), the Total Effective Dose Equivalent from licensed operation to the maximum individual during the report period, is 6.24 mrem. This is a summation of Direct Radiation Exposure (calculated by comparing the maximum of all perimeter TLD exposures to TLD exposure at the REMP control location) plus Effluent Doses (calculated per the I ODCM) . Members of the Public Doses Due To Their Activities Inside The Site Boundary I The radiation doses for MEMBER(S) OF THE PUBLIC due to their activities inside the site boundary are not greater than the doses listed in this table to show compliance with 40 CFR Part 190 or 10 CFR 20.1301 . Evaluations have shown that exposure time for individuals not occupationally associated with the plant site is minimal in comparison to the exposure time considered I for the dose calculation at or beyond the site boundary. Therefore, a separate assessment of radiation doses from radioactive effluents to MEMBER(S) OF THE PUBLIC, due to their activities inside the site boundary, is not necessary for this report period. I Compliance with 10 CFR 72.44(d)(3) f.or Dry Fuel Storage While there are minimal gaseous and liquid effluents specifically from the Independent Spent Fuel Storage Installation (ISFSI) , there is a contribution from Direct Radiation. The doses listed in this section include the contributions from the ISFSI. I I I

I
- 1) Missed ODCM surveillances (CR-2020-01743) - Carried over from 2019 Between the months of April 2019 and February 2020, there were multiple occasions of five types of ODCM I
surveillances missed due to a combination of poor work instructions, human performance errors and employee turnover caused by a vacant position. These errors were identified in and will be corrected by the site Corrective Action Program. Post evaluation after discovery ensured that no ODCM dose or dose rate limits were exceeded. I The specific surveillances were: SR 4.1 1.1.3.1, 31-day dose projection for liquid effluents, SR 4.11.4.2.1, 31-day dose projection for gaseous effluents, I SR 4.11.2.2.1, cumulative dose contributions from noble gases SR 4.11 .2.3.1, cumulative dose contributions from gaseous releases of particulates and iodines I SR 4.11 .1.2.1, cumulative dose contributions from liquid effluents,
- 2) Groundwater Extraction Well ISCO pump knocked over (CR-2020-03889)
I On May 1, 2020, the ISCO sample pump that collected the weekly extraction well groundwater sample for tritium was discovered to have been knocked over sometime during the preceding week, due to storms and heavy rainfall. This resulted in the 7-day composite sample being lost, and a missed surveillance of the extraction well. The sample pump was weighed down with rocks and fastened to a nearby railing to prevent similar occurences from happening in I the future, and the lost weekly sample was noted in the groundwater report.
- 3) Missing ODCM Sample Media {CR-2020-04014)
I During the 2R21 refueling outage, it was discovered that the sample media from the Unit 2 Equipment Hatch effluent air sampler (Gooseneck) for the final week of the outage could not be located to complete the ODCM weekly surveillance. The Unit 2 RBC and Equipment Hatch had already been sealed and the equipment had already been removed from the area at the time of discovery, and an exhaustive search of Radiation Protection containment I storage and supply boxes failed to turn up the missing media, nor could any record of the sample media being counted be located on count room computers. Previous Equipment Hatch gooseneck samples were assessed, and it was determined that there was a reasonable certainty that the missing sample media would have contained radioisotopes that needed to be recorded in a I discharge permit, had they been collected and counted. RWDA-G-U2GC2020-128 was generated, based on a previous Equipment Hatch sample, to capture the approximate isotopic mix released during the final week of 2R21 , and an Outage Poll was submitted to RP to include the collection of the Equipment Hatch goosneck sample at the I end of future Unit 1 and Unit 2 outages.

SUMMARY
and INDEX Report Overview: I The AREOR provides a detailed summary of the BVPS Radiological Environmental Monitoring Program (REMP). During the report period, samples of air, water, shoreline sediment, milk, I* fish, food crops, feed crops, vegetation, and direct radiation (in the vicinity of the BVPS site) have been measured, analyzed, evaluated, and summarized. During the report period, the BVPS radioactive effluent releases (as performed in accordance with the Radiological Effluent I Technical Specification (RETS) program), did not exceed the limits identified in the BVPS Operating License, Technical Specifications and/or the Offsite Dose Calculation Manual (ODCM). The results of REMP verify that the effluent releases did not impact the environment with a measurable concentration of radioactive materials and/or levels of radiation that are higher than expected. Description of Pre-operational REMP (1974 - 1975): I. A pre-operational REMP was performed during the period 1974 through 1975. At that time, samples were collected and analyzed to determine the amount of radioactivity present in the I environment prior to BVPS operation. The resulting values are considered a "baseline" to which current sample analyses can be compared. A summary of the pre-operational data is summarized in Table 2-3 of this report. I Description of Operational REMP {1976 - Present): I The operational REMP was initiated during calendar year 1976 and continued through the report period. During the past forty (43) years, radiation and radioactivity in the environment was I monitored within a 10-mile radius of the site. A description of the operational REMP is outlined in Table 2-1 of this report. In general, two (2) types of samples were collected and compared during the report period, and are described as follows: I
- Control Samples: These samples are collected from areas that are beyond measurable influence of BVPS operation and are used as reference data. Normal background radiation I
levels, or radiation present due to causes other than BVPS operation, can thus be compared to the environment surrounding the BVPS site. During the report period, two hundred fifty- I nine (259) analyses were performed on samples from the control locations. This includes eight (8) analyses that were completed for thermoluminescent dosimeters (TLDs) at the control locations. Results of the analyses from the control locations are summarized in Table I 2-2 of this report.
- Indicator Samples: Indicator samples are collected to determine the radiological impact of I
BVPS operation in the environment. These samples are collected from various locations near I lll I

SUMMARY
and INDEX I the BVPS site. At a minimum, the samples are collected from areas where the BVPS contribution would indicate the most significant radiological impact. During the report I period, one thousand five hundred eight (1,508) analyses were performed on samples collected from eighty-one (81) indicator locations. In addition, five hundred twenty (520) analyses were completed for TLDs at the indicator locations. Results of the analyses from I the indicator locations are also summarized in Table 2-2 of this report.
- Comparisons: Current analysis results from the indicator samples were compared to both I current control sample values and the pre-operational baseline to determine if changes in radioactivity levels were attributable to BVPS operation.
I Determination of Environmental Impact I
- 2020 Sample Media and Analyses: Results for drinking water, surface water, shoreline stream sediment, fish, cow milk, goat milk, feedstuff, foodcrops, air particulate and air radioiodine media remained consistent with previous data. Minor increases and decreases I were noted in most sample media, and any positive results attributable to the BVPS operation were consistent with station data of authorized radioactive discharges and were within limits I permitted by the operating license and the ODCM. Other radioactivity detected was attributable to naturally occurring radionuclides, previous nuclear weapons tests, other man-made sources, and to the normal statistical fluctuation for activities near the Lower Limit of I Detection (LLD).
- Airborne Exposure Pathway: This ODCM required pathway was evaluated via sampling of I airborne radioiodine and airborne particulates. The results during this report period were similar to previous years. There was no notable increase in natural products and no I detectable fission products or other radionuclides in the airborne particulate media during the year attributed to effluent releases from BVPS.
I
- Direct Exposure Pathway: This ODCM required pathway was evaluated via measurement of environmental radiation doses by use of Thermo Luminescent Dosimeters (TLDs). The results of TLD processing have indicated a stable trend and compare well with previous I years.
I
- Ingestion Exposure Pathway: This ODCM required pathway was evaluated via sampling of milk, fish, and foodcrops (leafy vegetables).
I For milk samples, strontium-90 (attributable to past atmospheric weapons testing), was detected at levels similar to those of previous years. The gamma spectrometry analyses I I lV

SUMMARY
and INDEX indicated positive results for naturally occurring potassium-40 at average environmental I levels. The fish samples indicated below LLD levels in each of the sample analyses. I Foodcrop (leafy vegetation) samples indicated naturally occurring potassium-40 at average environmental levels. I
- Waterborne Exposure Pathway: This ODCM pathway was evaluated via samples of I drinking water, ground (well) water, surface (river) water and river sediment.
Water samples were analyzed for tritium and gamma-emitting radionuclides. Tritium was I identified in the indictor water samples. The value was well below the required LLD (2,000 picoCurie/liter). Iodine-131 analysis of drinking water indicated positive analyses, but the values were consistent with iodine-131 at the upstream surface (river) water control location I and was not due to liquid effluent releases from BVPS. I Sediment samples were collected from upstream of the site, at the discharge point of BVPS liquid effluent releases, and downstream of the site. Analysis of samples indicated naturally occurring radionuclides potassium-40, thallium-208, bismuth-214, lead-212, lead-214, I radium-226, and actinium-228 in all results. The analyses also indicated cesium-137, but the values were consistent with cesium-137 at the control location, and most likely caused by previous nuclear weapons tests. Cobalt-58 and cobalt-60 were identified in some of the I samples obtained at the shorelines of the BVPS Main Outfall Facility. This is not unusual because the BVPS site discharges cobalt-58 and cobalt-60 in liquid waste effluents. The I activity detected at these sample locations is consistent with discharge data of authorized liquid effluent releases, and all liquid effluent releases during the report period did not exceed the release concentration limits set forth in the ODCM. I
- Other Exposure Pathways: In addition to the samples collected from the exposure pathways described above, other media (i.e., feedstuff) were also collected. Results were I
consistent with previous years, with no degrading trends.
- Offsite Groundwater Monitoring (Historical): Since these samples are not required, they will no longer be collected as of 2017. For historical information, groundwater was collected semiannually by grab samples at locations within four (4) miles of the site, one (1) well in Hookstown, PA and one (1) well in Georgetown, PA. Each ground water sample was analyzed for tritium and is analyzed by gamma spectrometry.

- Individual Dose vs. Natural
Background:
The radiation doses to man as a result of BVPS operations were calculated for both gaseous and liquid effluent pathways using computer software RADEAS which was newly implemented in 2019. The computer software follows I Regulatory Guide 1.109 and site ODCM methodology. Dose factors listed in the ODCM are used to calculate doses from radioactive noble gases in discharge plumes. BVPS effluent I data, based on sample analysis were used as the radionuclide activity input. The total doses to an individual were evaluated for all liquid and gaseous effluent pathways. The calculated dose to an individual member of the public from liquid effluent release was 0.0230 mrem I whereas the gaseous effluent release was 0.3111 mrem. The incremental increase in total body dose from the operation of BVPS - Unit 1 and 2, is 0.0539% of the annual radiation
- 1 exposure. Figure i-1 illustrates the individual dose from BVPS effluents and natural background dose.

SUMMARY
and INDEX
- Summary: During the report period, radioactive effluent releases from the BVPS site did I not exceed the limits identified in the BVPS Operating License, Technical Specifications and/or the ODCM. The BVPS operational REMP program was followed throughout the report period. The results demonstrate the adequacy of radioactive effluent control at BVPS, I
and that BVPS operation did not adversely affect the surrounding environment. Positive results were attributable to BVPS operation and were consistent with station data of authorized radioactive discharges within limits permitted by the NRC license and the I ODCM. Other radioactivity detected was attributable to naturally occurring radionuclides, previous nuclear weapons tests, other man-made sources, and to the normal statistical I fluctuation for activities near the LLD. Inter-laboratory Comparison Programs: I
- Split Sample Program: BVPS shared split samples with the Pennsylvania Department of Environmental Protection (P ADEP) in support of their nuclear power plant monitoring I
program. The shared media and number of locations were typically comprised of milk (2), surface water (2), river sediment (1), fish (1), foodcrops (2), co-located air particulate/air I iodine (4), and TLD (24). The split sample program was coordinated by the state, and the results are not provided with this report. I
- Spike Sample Program: Spiked samples were provided by an independent laboratory and then analyzed by the REMP contractor laboratory. The samples were provided throughout the report period and included water samples, milk samples, filter paper samples and I
charcoal cartridge samples. A total of one hundred six (106) analyses were performed in 2020. One hundred five (105) analyses met the NRC acceptance criteria and one analysis deviated. I Special Reports: I
- Since no reporting levels were exceeded during 2020, no Special Reports were required. A Special Report shall be submitted to the NRC when (1) levels of radioactivity in an I environmental sampling medium exceeds the limits specified in ODCM procedure 1/2-ODC-3 .03, Attachment Q Table 3.12-2, and when (2) the results of the following calculation are

I Beaver Valley Power Station R1LA9.690E 2_020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 1 - INTRODUCTION I A. Radiation Fundamentals I Radiation is the conveyance of energy through spa.ce. For example, heat emanating from a
~ve is a f~ of radiation, as are light rays, micro~ves, and ~o wa~es: Ali matter
~ r * * ,* * * * '
consists bf atoms, which are comprised_ of positjvt:lY charged particles (protons), negatively I c~ed particles_ (electrons), and non-cbargedlneutraf paiticies (t;t~utrons). Tbe ~latively large particles (protons and n~utrons),are packed tjghtly tcigeth~ in a cluster at the center of
'the atom callecf the nucleus, while the smaUer partides (electrons) orbit around ~e nucleus.
I In an electrically neutral atom, the negative charges of the electrons *are balanced by the positjv~ 9~~s_ ~f ~e protons, . Due to their dissin:µlar charge~, the ~jo°:8~.'1:'~ electrons I ha".@ a strong~attraption for each.other. This holds th,e,~ together. Qther ~tjve forces between the protons and neutrons keep the densely packed protop.s from repelling eac,h other and prevent the nucleus from breaking apart. I B. Radiation and Radioactivity I The following provides an alphabetical glossary of terms associated with radiation, radioactivity, and the*radioactive decay process. The terms discussecf include alpha particles, beta particles, gamma rays, genetic effects, half-life, ioniz.ation, isotopes, neutrons, radiation, I radioactive decay, radionuclides and somatic effects. I Alpha Particles: Particulate and electromagnetic radiation each travel through matter differently because of their different properties. Alpha particles contain 2 protons and 2 neutrons, are relatively large, and carry an electricaf charge of +2. Alpha particles are I ejected from the nucleus of a radioactive 'atom at speeds ranging from 2,000 to 20,000 miles per second. However; due to its comparatively large ~ . ai:i alpha particle usually does not I travel very far before it loses most of its energy through collisions and interactions with other atoms. As a result, a sheet of paper or a few centimeters of air can easily stop alpha particles. I Beta Particles; Beta particles are very small, and comparativ~ly fast particles, traveling at speeds near the speed of light (186,000 miles per second). Beta particles have an electrical charge of either +1 or -1. Because they are so smalf and have* a low charge, they do not I collide and interact as often as alpha particles, so they can travel farther. Beta particles can usually travel through several meters in air but may be stopped by a thin piece of metal or I wood. I I I 1-1
Beaver Valley Power Station RTL A9.(?90E I 2020 Annual Radiological Environmental Operating Report SECTION 1 - INTRODUCTION Enclosure 3 I Gamma Rap: Gamma rays are pure energy and travel at the speed of light. They have no I measurable charge or mass and generally travel much farther than alpha or beta particles before being absorbed. After repeated interactions, the gamma ray loses its energy and v~shes. The ran~e of a gamma ray in air v8!ies, depending on the ray's energy and I interactions. Very high-energy~ radiation can travel a considerable distance, where as low energy gamma radiation ' ' may travel only a few feet in air. Lead is used as shielding I material for gatnma radiation because of its density. Several inches of lead or concrete may be needed to effectively shield gamma rays. I Genetic Effects: The effects of ionizing radiation which are observed in the offspring of the exposed individual that could occur as a result of ionizing radiation interacting with the genes in the human cells. I Half-life: The length of time an atom remains radioactive is defined in terms of half-life, I which is the amount of time required for a radioactive substance to lose half of its activity through the process of radioactive decay. Radionuclides that have infrequent emissions have a long half-life, where as, radionuclides that have more :frequent emissions have a short half. I life. Ionhation: Through interactions with atoms, alpha, beta, and gamma radiation lose their I energy. When these forms of radiation interact with any form of material, the energy they impart may cause atoms in that material to become ions or charged particles. Normally, an I ato11:1 has the same n:umber of protons as electrons, thus, the number of positive and negative charges cancel, in which the atom is electrically neutral. When one or more electrons are remo,ved, an ion is formed. Ionization is one of the processes that may result in damage to I biological systems. I Isotopes: A group of identical atoms containing the same number of protons make up an element In fact, the number of protons an atom contains determines its chei;nical identity. For instance, all atoms with one proton are hydrogen atoms, and all atoms with eight protons I are oxygen ~toms. However, the number of neutrons in the nucleus of an element may vary. Atoms with the same number of protons but different numbers of neutrons are called isotopes. Different isotopes of the same element have the same chemical properties, and I many are stable or non-radioactive. An unstable or radioactive isotope of an element is called a radioisotope, a radioactive atom, or a radionuclide. Radionuclides usually contain an I excess amount of energy in the nucleus. The excess energy is usually due to a surplus or deficit in the number of neutrons in the nucleus. Radionuclides such as uranium-238, beryllium-7 and potassium-40 occur naturally. Others are man-made, such as iodine-131, I cesium-137, and cobalt-60. I 1-2 I
I Beaver Valley Power Station RTI, A9.690E 2020 Annual Radiological Environmental Operating Report Enclosme 3 I SECTION 1 - INTRODUCTION I Neutronsi Neutrons come from several sources, including the interactions of cosmic I radiation with the earth's atmosphere* and nu.clear reactions within operating nu.clear power reactors. However, neutrons are not of environmental concern since the neutron source at nuclear power stations is* sealed within the containment building. * ~use neutrons have no I charge, they are- able to pass very cl~ to the"nuclei of the material through which they are traveling. As a result;- neutrons may 'be captured by one of these riuclef or they may be I deflected. When deflecte4 the neutron Ioks some of its energy. After a series of these deflections, the neutron has lost most-of its energy. At this point; the neutron moves about as slow as the atoms ?f-the inaterial- through which it is traveling and is called a thermal I neutron.
- In comparison, fast neutrons are much more energetic than thermal neutrons and have greater potential for causing damagefo the material through'which they travel. Fast neutrons can have from 200 thousand to 200 million tinies the energy of thermal neutrons.
I Neutron shielding is designed to slow fast neutrons and absorb thermal neutrons. Neutron shielding materials commonly used to slow netitions down are water or polyethylene. The I shield is then completed with a material such as cadmru.m, to *absorb ilie now thermal neutrons. Concrete is also used to form an effective neutron shield because it contains water molecules and can be easily molded around odd shapes. I Radiation: This is the conveyance of energy through space. For instance, heat emanating I from a stove is a form of radiation, as are light rays, microwaves, and radio waves. Ionizing radiation is another type of radiation and has similar properties to those of the examples listed above. Ionizing radiation consists of both electromagnetic radiation and particulate I radiation. El~magnetic radiation is energy with no measurable mass that travels with a wave-like mo~on through space. Included in this category* are gamma rays and x-rays. Particulate radiation consists of tiny, fast moving pa_rticles which, if unhindered, travel in a I straight line through space. The three types of particulate radiation of concern to us are alpha particles, 'Which are made up of2 protons and 2 neutrons; beta particles, which are essentially I free electrons; and neutrons. The properties of these types of radiation will be described more fully in the Range and Shielding section. I I I I I 1-3

Rrufa;>active atoms may decay directly to a I stable ~ or may go through a series of decay stages, called a radioactive decay series, and produce several daughter products that evenlw!llY result in a stable atom. The loss of energy through radioactive 4ecay nµty transform the atom into a ~hemically different I clement For example, when uranium-238 decays, it emits an alpha particle and, as a result, the ~om loses 2 protons ~d 2 neutrons. Since the number of protons in the nucleus of an I atom. determines~ ch~cal identity, then when the uranium.~238 atom loses the 2 protons and 2 ne,utrons, it is transformed into lµ]. atom oftho.rium-234. Thorium-234 is one of the 14 successive daughter ~~ of uranium-238. Radon is another daughter pro_duct, and the I depay series ends with stable lead-206. The following example is part of a known radioactive decay series, called the uranium series, which begins with uranium-238 and ends with lead-206.

One curie indicates the disintegration of37 billion atoms per second. A curie is a unit of activity, not a quantify o( material°' Thus, the amount of I material required to produce one curie varies. A smaller unit of the curie is used when di.s;Cussing the low CQncentrations- of radioactivity~ in envµ-onmental samples. For I ~ c e , the.pi~urie (pCi) represents OD(? tpllionth of a curie.
Absorbed Dose (rad}: This is a term used to describe the radiation energy absorbed by any I D)atepal exposed to ionizing radiation and can be U&ed for both particulate and electromagnetic radiation. The rad is the unit used to measure the absorbed dose. It is defined as the energy of ionizing radiation deposited per gram of absorbing material (I rad = I 100 erg/g). The rate of absorbed dose is usually given in rad/hr. The rad is not used to quantify biological damage caused by ionizing radiation. I Dose Eq!9!alept_(ry_m): Biological damage due to alpha, beta, gamma ancJ nel.$:On radiation may r:esult from ionipng-radiation, Some-types of radiation; especially alpha particles, cause I d ~ local ioni?,ation and can result in up to 20-times_ the amo~t of.biological damage for the ~ e energy i m ~ as <Jo gamma or x-rays.

When the quality f~r is multiplied by the al:>sorbed close (rad) the result is the dose equivalent. Dose equivalent is an estimate of the possible biological damage resulting I from exposure to a particular type of ionizing radiation and is measured in rem. An example of this conversion from absorbed dose (rad) to dose ~valent (rem) uses the quality factor for alpha radiation, which is equal to 20. Thus, 1 rad of ~lpha radiation is equal to 20 rem.
I Since beta and g ~ radiation each have a quality fac:tor of 1, then 1 rad of either beta or gamma radiation is equal to 1 rem. Neutrons have a quality factor ranging from 2 to 10. In I terms of radiation, the rem is a relatively large unit Therefore, a smaller unit known as the millirem, is often used and one millirem (mrem) is equal to 1/1000 of a rem. I I 1-5
RTLA9.690E I Beaver Valley Power Station 2020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 1 - INTRODUCTION I D. Lower Limit of Detection The Lower Limit of Detection (LLD) for environmental samples is a calculated value that I represents an a-priori (before-the-fact) limit for the smallest concentration (i.e.; pCi per unit mass or volwne) of radioactive material in a sample that will be detected with 95% probability, and with 5% probability of falsely concluding that a blank observation represents I a real signal. A calculated LLD must consider analytical variables such as standard deviation of the background counting rate, counting efficiency, sample size, :fractional radiochemical I yield, radioactive decay constant, and elapsed time between sample collection and time of counting. I E. Scope and Objectives ofREMP I The environmental program consists of environmental monitoring for radioactivity in the vicinity ofBVPS. Environmental sampling and analyses include air, water, milk, vegetation, river sediments, fish, and ambient radiation levels in areas surrounding the site. The results I of these media are assessed to determine impacts of the plant operation on the environment. The ARBOR for BVPS summarizes REMP conducted by the licensee during the report period. I F. Description of the Beaver Valley Site I BVPS is located on the south bank of the Ohio River in the Borough of Shippingport, Beaver County, Pennsylvania, on a 453 acre tract of land The-site is approximately one mile from I Midland, Pennsylvania, five miles from East Liverpool, Ohio, and twenty-five miles from Pittsburgh, Pennsylvania. Figure 1-1 shows the site location in relation to the principal population centers. Population density in the immediate vicinity of the site is relatively low. I The population within a five mile radius of the plant is approximately 15,000. The only area within the radius of concentrated population is the Borough of Midland, Pennsylvania, with a I population of approximately 2,435 as determined from the 2020 U.S. Census. The site lies in a valley along the Ohio River. It extends from the river (elevation 665 feet I above sea level) to a ridge along the border south of the Beaver Valley Power Station at a maximum elevation of 1160 feet. Plant grade level is approximately 735 feet above sea I level. BVPS is on the Ohio River at river mile 34.8, a location on the New Cumberland Pool that is I 3.1 river miles downstream from Montgomery Lock and Dam, and 19.6 miles upstream from I 1-6 I

The Pennsylvania-Ohio-West Virginia border is located I 5.2 river miles downstream from the site. The river flow is regulated by a series of dams and reservoirs on the Beaver, Allegheny, Monongahela and Ohio Rivers and their tributaries. During the report period, the Ohio River flow (as obtained from the Corps of Engineers - I Water Resources Engineering) at the New Cumberland Dam ranged from 2,485 cubic feet per sec.ond (minimum monthly average) to 172,228 cubic feet per second (maximum monthly average). The mean flow during the report period was approximately 44,779 cubic I feet per second. Water temperature of the Ohio River typically varies from 32.0° Fahrenheit to 81.1 ° Fahrenheit. The minimum temperatures occur in January and/or February and I maximum temperatures in July and/or August Water quality in the Ohio River at the site location is affected primarily by the water quality of the Allegheny, Monongahela and Beaver rivers. I The climate of the area may be classified as humid continental. The predominant wind I direction is typically from the southwest in summer and from the west in winter. The National Climatic Data Center indicates the following data for the Beaver Falls, PA area: The total annual precipitation during the report period was 44.2 inches. I The average mean temperature during the report period was 51.8° Fahrenheit.

Because the I two systems are isolated from each other, primary and secondary waters do not mix, and radioactivity in the primary system water is normally isolated from the secondary system. Reactor coolant in the primary system is pumped through the reactor core and steam I generators by means of reactor coolant pumps. Heat is transferred from the primary system to the secondary system in the steam generators. The steam is then formed and delivered to I the main unit turbine, which drives the electrical generator. The steam is condensed after passing through the turbine and returned to the steam generators to begin another steam/water cycle. I I 1-7

Air Monitoring Characterization of Air and Meteorology I 1. The air near the site contains pollutants typical for an industrial area. Air flow is I generally from the southwest in summer and from the northwest in the winter.
- 2. Air Sampling Program and Analytical Techniques I a. Program I, The air is sampled for gaseous radioiodine and radioactive particulates at each of eight (8) offsite air sampling stations. The locations of these stations are listed in I Table 2-1 and shown on a map in Figure 2-1.
Samples are collected at each of these stations by continuously drawing two cubic I feet per minute of atmosphere air through a glass fiber filter paper and a charcoal cartridge. The glass fiber filter paper is used for collection of airborne particulates, 1_ while the charcoal cartridge is used for collection of radioiodine. Samples are collected on a weekly basis. I The charcoal cartridge is used in the weekly analysis of airborne iodine-131. The glass fiber filter papers are analyzed each week for gross beta, then composited by the station each quarter for gamma spectrometry analysis. In order to reduce interference I from short-lived naturally occurring radioactivity (e.g. radon and thorium), the glass fiber filter papers are allowed to decay prior to performing beta analysis in a low ,I background counting system. Gross Beta Anafysis 9f Filter Paper: Analysis is performed by placing the glass fiber I filter paper from the weekly air sample in a 2-inch planchet followed by analysis in a low background, gas flow proportional counter. I Gamma Emitter Analysis of Filter Paper: Analysis is performed by stacking all of the glass fiber filter papers ~liected from each monitoring station during the quarter and scanning the composite on a high-resolution germanium gamma spectrometer. _I ,, lodine-131 Analysis of Charcoal of each charcoal cartridge.

- 3. Results and Conclusions I
A summary of data is presented in Table 2-2. I. a Airborne Radioactive Particulates .1 Gross Beta: A total of four hlmdred sixteen (416) weekly samples from eight (8) locations were analyzed for gross beta. The results were comparable to that of previous years. Figure 2-2 indicates the weekly average concentration of gross beta I in air particulates.
.I Qamma Spectrometry: A total of thirty-two (32) quarterly samples were composited from eight (8) locations and analyzed for gamma spectrometry. Naturally occurring beryllium-7 was identified in twenty-eight of twenty-eight (28 of 28) indicator I
samples, and four of four (4 of 4) control samples. No other gammas were identified. A summary of the analysis results during the report period are listed in Table 2-2. A trend graph of analyses (including the pre-operational period through the report I period) is shown on Figure 2-2. I Deviations from Required Sampling and Analysis Schedule: There were seven deviations from the required airborne particulate sampling and analysis schedule during the report period. I During the sampling period of 03/23/2020 - 03/30/2020, REMP Air Particulate and Iodine sampling st:iµion located at the Midland North Sub Station (Site No. 32, Sector I 15, 0.75 miles NW) was out of service. A Du~e Light employee was not available on the scheduled change-out date (03/30/2020); therefore, the REMP
,1 technician was not permitted on site until 3/31/2020 (08:58), at which time the station was found to be out-of-service. Upon investigation, it was determined that a fuse was blown in the pump. (Date and time of malfunction was 03/28/2020 at 15 :48 as I
conveyed from the calculated volume.) (CR-2020-03313) During the sampling period of 04/06/2020 - 04/13/2020, REMP Air Particulate and Iodine sampling station at Brunton's Dairy in Aliquippa (Site No. 27, Sector 7, 6.16
)
I miles SE) was found to be out of service. The cause was a tripped circuit breaker on the front of the totalizer. The circuit breaker was reset and the station was returned to I, operation on 04/13/2020. The sample station was out of service for approximately 94.07 hours as reported by the REMP technician.

I Beaver Valley Power Station RTLA9.690E 2020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM I C. Environmental Radiation Monitoring I. Description of Regional Background Radiation and Sources I Historical information for regional background was obtained from Reuter-Stokes I instruments that were previously located within a five (5) mile radius of the BVPS site. Data is no longer available from these instruments, but historical data indicated that the background exposure rates ranged from 6 µR/hrto 12 µR/hr. I The sources of background radiation are affected by the terrain in the vicinity of BVPS, .I whereas, the local hills (i.e. altitude variations of 300-400 feet) and densely wooded areas contribute to variations in background radiation. Other sources (e.g. radon) are affected by the geological features of the region, which are characterized by nearly flat-laying I sedimentary beds of the Pennsylvania age. For information, the local sedimentary beds of limestone alternate with sandstone and shale with abundant interbedded coal layers. Pleistocene glacial deposits partially cover the older sedimentary deposits in the I northwest. Most of the region is underlain by shale, sandstone, and some coal beds of the Conemaugh Formation. Outcrops of sandstone, shale, and limestone of the Allegheny Formation exist within the Ohio River Valley and along major tributary streams.
- 2. Locations and Analytical Procedures I Ambient external radiation levels around the site were measured using 1LDs.
I During the report period, there were a total of sixty-five (65) environmental TLD locations. This is comprised of forty-four (44) offsite locations, along with twenty-one I (21) fence perimeter locations. The offsite TLD locations are plotted on Figure 2-3, but the fence perimeter locations are not plotted due to the large scale of the figure. I The TLDs were annealed at the Contractor Central Laboratory shortly before placing the TLDs in their field locations. The radiation dose accumulated in-transit between the Central Laboratory, the field location, and the Central Laboratory was corrected by I transit controls maintained in lead shields at both the Central Laboratory and the field office. All dosimeters were exposed in the field for a calendar quarter, in a specific I holder that contains two (2) 1LDs at each location. I I I 2-29

- 3. Results and Conclusions A summary of the TLD results during the report period are listed in Table 2-2. A trend graph of analyses (including the pre-operational period through the report period) is shown on Figure 2-4.
TLD Analysis: During the report period, the average quarterly external exposure rate (as measured from TLD) was 17.5 mR at the sixty-five (65) indicator locations, and 19.4 mR at the control location. This external exposure rate is comparable to previous years. As I expected, there was some variation in external exposure rate among locations and seasons. I Deviations from Reguired Sampling and Analysis Schedule: There were no deviations from the required direct radiation monitoring schedule during the report period. I Summary: The quarterly TLD external exposure rates are comparable to that of the previous decade. There was no evidence of anomalies that could be attributed to the I operation of BVPS. It should also be noted that the average external exposure rate at the indicator locations was less than average external exposure rate at the control location. Based on all the analytical results and the comparison to pre-operational levels, the I operation of BVPS did not contribute any measurable increase in external exposure in the vicinity of the site during the report period. The TLD exposure rates also confirm that I changes from natural radiation levels, if any, are negligible.

I Beaver Valley Power Station RTLA9.690E 2020 Annual Radiological Environmental Operating Report Enclosure 3 SECTION 2-ENVIRONMENTAL MONITORING PROGRAM D. Monitoring of Surface Water, Drinking Water, Groundwater, and Precipitation I
- 1. Description of Water Sources I
The Ohio River is the main body of water in the area and is the main surface water supply for drinking water in the area. The Beaver Valley Power Station obtains water from the Ohio River for plant make-up water and discharges water to the Ohio River via I National Pollutant Discharge Elimination System (NPDES) discharge points (e.g. cooling tower blowdown, liquid effluent releases, etc.). I The Ohio River is the main surface water supply source for towns, municipalities, and industries both upstream and downstream of the BVPS site. The nearest user of the Ohio River as a potable water source is Midland Borough Municipal Water Authority. The intake of the treatment plant is approximately 1.5 miles downstream of the Midland Borough Municipal Water Authority and is located on the opposite side of the river. The next downstream user is East Liverpool, Ohio and is approximately 6 miles downstream. The heavy industries in Midland, as well as other users downstream, also use river water I for cooling purposes. Groundwater occurs in large volumes in the gravel terraces which lie along the river and I diminishes considerably in the bedrock underlying the site. Normal well yields in the bedrock are less than ten (10) gallons per minute (gpm) with occasional wells yielding up I to 60 gpm. In general, the BVPS site experiences cool winters and moderately warm summers with I ample annual precipitation evenly distributed throughout the year. The National Climate Data Center indicated the total annual precipitation during the report period for the Beaver Falls, PA area was 44.2 inches. I
- 2. Sampling and Analytical Techniques I
- a. Surface (Raw River) Water I
The sampling program of river water included three (3) sampling points along the Ohio River for most of 2016. In December 2016, one of the locations closed in which the program now includes two (2) sampling points. I Furthermore, Site No. 2.1, Sector 14, Midland - A TI Allegheny Ludlum, the I downstream sample, is no longer a viable sample location. ATI permanently closed the Midland facility in 2016. As of December 2016, surface water samples were no I 2-34 I
I Beaver Valley Power Station RTLA9.690E 2020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM I longer available. Site No. 5, Sector 14, East Liverpool Water Department was an additional downstream sample location in which grab samples were taken. The East Liverpool site was transitioned to a composite sample location thus replacing A TI I Allegheny Ludlum. I- Raw water samples were collected daily at the Water Treatment Plant in East Liverpool, OH, sample location 5, [River Mile 41.2], and then made into a weekly composite sample. Now the water sample is collected with a composite water I sampler. The automatic sampler takes a 20-40 mL sample every 15 minutes and samples are collected on a weekly basis. The weekly samples are then combined for I a monthly composite sample for each location. The monthly composite samples are analyzed for gamma emitters. In addition, a quarterly composite sample is prepared from the monthly composites for each sample point. Quarterly composites are I analyzed for hydrogen-3 (tritium). One automatic river water sampler, located at the ATI-Allegheny Ludlum (formerly J&L Steel) river water intake, sample location 2.1, [River Mile 36.2], was transitioned to East Liverpool due to the closing of the I facility. A weekly grab sample is taken upstream of the Montgomery Dam, sample location 49 [River Mile 29.6]. This upstream sample at the Montgomery Dam is the control sample. The weekly grab samples upstream of the Montgomery Dam are analyzed for I iodine-131. Weekly grab samples are then made into monthly composites and are analyzed for gamma emitters. Quarterly composites are prepared from each of the monthly composites. The quarterly composites are analyzed for tritium. Locations of I each sample point are shown in Figure 2-5. I b. Drinking Water {Public Suimlies) Drinking water (i.e. treated water) is collected at both the Water Treatment Plant in I Midland, PA, sample location 4, and the Water Treatment Plant in East Liverpool, OH, sample location 5. An automatic sampler at each location collects 20-40 mL I every 20 minutes, which is then combined for a weekly composite sample. The weekly composite sample from each location is analyzed for iodine-131. Monthly composites are prepared from the weekly samples and are analyzed by gamma I spectrometry. In addition, a quarterly composite sample is prepared for each sample point from the monthly composites. Quarterly composites are analyzed for tritium. A weekly grab sample is taken upstream of the Montgomery Dam, sample location I 49A [River Mile 29.6]. This upstream sample at the Montgomery Dam is the control sample. The weekly grab samples upstream of the Montgomery Dam are analyzed for I iodine-131. Weekly grab samples are then made into monthly composites and are 2-35 I
Beaver Valley Power Station RTLA9.690E I 2020 Annual Radiological Environmental Operating Report SECTION 2 -ENVIRONMENTAL MONITORING PROGRAM Enclosure 3 I analyzed by gamma spectrometry. Quarterly composites are prepared from each of the monthly composites. The quarterly composites are analyzed for tritium. I Locations of each sample point are shown in Figure 2-5. I
- c. Groundwater Since these samples are not required, they will no longer be collected as of 2017.
I For historical information, groundwater was collected semiannually by grab samples at locations within four (4) miles of the site, one (1) well in Hookstown, PA and one I (1) well in Georgetown, PA. Each ground water sample was analyzed for tritium and is analyzed by gamma spectrometry. I
- d. Precipitation Since these samples are not required, they will no longer be collected as of 2017.
I For historical information, precipitation was collected in Shippingport, PA, East Liverpool, OH, and Weirton, WV. Precipitation, when available, was collected each I week and combined for quarterly composite samples from the weekly samples. The quarterly composites were analyzed for tritium and gamma emitters. I
- e. Procedures Gamma Analysis of Drinking Water and Surface Water: The analysis is performed by I
placing one liter of the sample into a Marinelli container and analyzing on a high-resolution germanium gamma spectrometry system. Although not required by the I ODCM, this analysis is also performed on groundwater and precipitation samples. Tritium Analysis of Drinking Water and Surface Water: The tritium is determined in I water samples by liquid scintillation analysis. Although not required by the ODCM, this analysis is also performed on surface water, groundwater and precipitation I samples. Iodine-131 Analysis of Drinking Water: The sample is chemically prepared and I analyzed with a low-level beta counting system. Although not required by the ODCM, this analysis is also performed on surface water samples. I I I 2-36 I

Results and Conclusions A summary of the analysis results of water samples (surface water, drinking water, I ground water, and precipitation) during the report period are listed in Table 2-2. A trend graph of analyses (including the pre-operational period through the report period) is I shown in Figures 2-6 through 2-9.
- a. Surface Water I Tritium: A total of eight (8) surface water samples were analyzed for tritium during the report period. Tritium was not detected in the four (4) indicator samples nor the I four (4) control samples.
I Gamma Spectrometry: A total of twenty-four (24) surface water samples were analyzed by gamma spectrometry during the report period. Gamma emitting radionuclides were not detected in the twelve (12) indicator samples, nor were they I detected in the twelve (12) control samples. Iodine-131: Although not required by the ODCM, a total of twenty-six (26) surface I water control samples were analyzed for iodine-131 using radiochemical methods during the report period. Iodine-131 was detected in four of twenty-six (4 of 26) I weekly control samples, of which zero (0) analysis exceeded the reporting level of 2 picocurie / liter. The results were similar to previous years, (current annual range= LLD to 0.50 picocurie / liter). The positive results were detected at the control I location, which is five (5) miles upstream (not influenced by BVPS operation). Identification of iodine-131 during the report period was most likely due to medical diagnostic and treatment procedures performed at upstream facilities. I
- b. Drinking Water I Tritium: A total of eight (8) drinking water samples were analyzed for tritium during the report period. Tritium was not detected in the four (4) indicator samples nor the I four (4) control samples.
Gamma Spectrometry: A total of twenty-four (24) drinking water samples were I analyzed by gamma spectrometry during the report period. Gamma emitting radionuclides were not detected in any of the twenty-four (24) indicator samples. I I 2-37 I

'I E. Monitoring of Shoreline Stream Sediment and Soil
- 1. Characterization of Shoreline Stream Sediment and Soil I The stream sediment (river bottoms) consists largely of sand and silt. Soil samples may vary from sand and silt to a heavy clay with variable amounts of organic material.
I
- 2. Sampling Program and Analytical Techniques I
- a. Program Shoreline stream sediment was collected semi-annually above the Montgomery Dam, and near the BVPS outfall structure. A Ponar or Eckman dredge is used to collect the sample. The sampling locations are also listed in Table 2-1 and are shown in Figure I
2-10. I Although not required by the ODCM, soil samples were collected at each of the nine (9) locations in 2015. In 2017, the locations were reduced from ten (10) to five (5), as well as the sample frequency was revised from once per three years to once every I five years. Soil was last sampled in 2015 and was recently performed in 2020. At each location, twelve (12) core samples (3" diameter by 2" deep) are gathered at prescribed points on a 10-foot radius circle. Each location is permanently marked I with reference pins. Each set of samples is systematically selected by moving along the radius in such a manner as to assure representative undisturbed samples. I Sampling locations are listed in Table 2-1 and are shown in Figure 2-10. Shoreline stream sediment and soil are analyzed for gamma-emitting radionuclides.
- b. Analytical Procedures I Gamma Emitter Analysis of Stream Sediment: Analysis is performed in a 300 mL plastic bottle and analyzed by gamma spectrometry.

I Beaver Valley Power Station RTLA9.690E 2020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM I 3. Results and Conclusions A summary of the analysis results during the report period are listed in Table 2-2. A I trend graph of analyses (including the pre-operational period through the report period) is shown on Figure 2-11 and Figure 2-12. I a. Shoreline Stream Sediment I Gamma Spectromett:y: A total of four (4) sediment samples were analyzed by gamma spectrometry during the report period. Naturally occurring potassium-40, cesium-I 137, thallium-208, bismuth-214, lead-212, lead-214, radium-226 and actinum-228, were detected in two of two (2 of2) indicator samples and two of two (2 of2) control samples. I Cesium-137: Radionuclide cesium-137 was identified in two of two (2 of 2) indicator samples and two of two (2 of 2) control samples. The results were comparable to that I of previous years (current annual range= 0.06 to 0.07 picocurie / gram) and less than the pre-operational level of 0.4 picocurie / gram. Also, because cesium-137 was I identified at the control location (upstream), then it was not due to plant effluent releases and is most likely residual contamination due from previous nuclear weapons tests. I Cobalt-58: Radionuclide cobalt-58 was identified in two of two (2 of 2) indicator samples and zero of two (0 of 2) control samples. The samples, which indicated I cobalt-58, were obtained at the shore line of the BVPS Main Outfall Facility. The results were comparable to previous years (current annual range = 0.07 to 0.23 I picocurie / gram), and the data is slightly higher than the BVPS Main Outfall Facility pre-operational level of 0.098 picoCurie / gram. I Cobalt-60: Radionuclide cobalt-60 was identified in two of two (2 of 2) indicator samples and zero of two (0 of 2) control samples. The samples, which indicated cobalt-60, were obtained at the shore line of the BVPS Main Outfall Facility. The I results were comparable to previous years (current annual range = 0.19 to 0.29 picocurie / gram), and the data is currently lower than the BVPS Main Outfall Facility pre-operational level of 0.4 picocurie / gram. I Deviations from Required Sampling and Analysis Schedule: There were no deviations from the required sediment sampling and analysis schedule during the I report period. I 2-43 I
Beaver Valley Power Station RTLA9.690E I 2020 Annual Radiological Environmental Operating Report SECTION 2 -ENVIRONMENTAL MONITORING PROGRAM Enclosure 3 I Summary: The identification of cobalt-58 and cobalt-60 in the shoreline stream sediment near the main outfall facility is not unusual because the plant discharges I these radionuclides in liquid effluent releases. The analyses are consistent with discharge data of authorized liquid effluent releases, and all liquid effluent releases I during the report period did not exceed the release limits set forth in the ODCM.
- b. Soil I
Gamma Spectrometry: A total of five (5) soil samples were analyzed by gamma I spectrometry during the report period. Naturally occurring potassium-40, thalium-208, bismuth-214, lead-212, lead-214, radium-226 and actinum-228, were detected in four of four (4 of 4) indicator samples and one of one (1 of 1) control samples. I Cesium-137: Radionuclide cesium-137 was identified in four of four (4 of 4) indicator samples and one of one (1 of 1) control samples. The results were similar to I previous years (current year range= 0.08 to 0.14 pico Curie I gram) and less than the pre-operational level of 1.2 pico Curie / gram. Also, because cesium-13 7 was I identified at the control location (Weirton), then it was not due to plant effluent releases and is most likely residual contamination from previous nuclear weapons tests. I Deviations from Reguired Sampling and Analysis Schedule: Two deviations from the I required soil sampling and analysis schedule occurred during the report period. Sample Point 46B, Industry-Willows Inn-Route 68, was paved over due to the new ownership/renovation of the Willow's Motel and Entertainment Center. Sample I Point 30A, Shippingport, PA, Cooks Ferry Substation, was relocated near the Air Monitoring Station within the same area. I Summary: The identification of cesium-13 7 in the soil samples around the plant is not unusual because these radionuclides have been found in the environment from previous nuclear incidents and testing.

Beaver Valley Power Station RTLA9.690E I 2020 Annual Radiological Environmental Operating Report SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM Enclosure 3 I F. Monitoring of Local Cow and Goat Milk I
- 1. Description - Milch Animal Locations I
Samples of fresh milk are obtained from milch animals at locations and frequencies noted in Table 2-1. The milk is analyzed for its radioiodine content, gamma emitters, strontium-89 and strontium-90. I Detailed field surveys are performed during the grazing season to locate and enumerate 'I milch animals within a five (5) mile radius of the site. Survey data for the most recent survey conducted is shown in Section 3, Land Use Census. I
- 2. Sampling Program and Analytical Techniques
- a. Program Cow milk was collected from the one (1) reference dairy farm within a 10-mile radius of the BVPS, Brunton Dairy Farm (6.076 miles southeast) and one (1) control location dairy farm outside of the 10-mile radius, Windsheimer Dairy Farm (10.475 miles south-southwest).
I Dairy cow sampling has been performed at Brunton Dairy since 2016, due to the I closure of Halstead Dairy and Searight Dairy in 2014. Additionally, one goat location was available for sampling and samples were obtained at the Covert Residence (2.131 miles southwest). I The dairies are subject to change based upon availability of milk or when more recent data (milch animal census, and/or change in meteorological conditions) indicate other I locations are more appropriate. I The milk samples are collected and analyzed biweekly when the animals are on pasture and monthly at other times. The monthly and/or biweekly sample is analyzed for principle gamma emitters (including cesium-137 by high resolution germanium I gamma spectrometry), and iodine-131 high sensitivity analysis. Although not required by the ODCM, the monthly and/or biweekly sample is also analyzed for strontium-89, strontium-90. I The location of each is shown in Figure 2-8 and described below. I I 2-48 I

- b. Procedure I Iodine-131 Analysis of Milk: The milk samples are chemically prepared, and then analyzed with a low-level beta counting system.
I Gamma Emitter Analysis of Milk: This is determined by gamma spectrometry analysis of a 1-liter Marinelli container of milk. I Strontium-90 Analysis of Milk: Although not required by the ODCM, the milk I samples are prepared by adding a stable strontium carrier and evaporating to dryness, then ashing in a muffle furnace, followed by precipitating phosphates. Strontium is purified in all samples by the Argonne method using 3 grams of extraction material in I a chromatographic column. Stable yttrium carrier is added, and the sample is allowed to stand for a minimum of 5 days for the in-growth ofyttrium-90 (Y-90). Yttrium is then precipitated as hydroxide dissolved and re-precipitated as oxalate. The yttrium I oxalate is mounted on a nylon planchet and is counted in a low-level beta counter to infer strontium-90 activity. I Strontium-89 Analysis of Milk: Although not required by the ODCM, the strontium-89 activity is determined by precipitating strontium carbonate (SrCO3) from the I sample after yttrium separation. This precipitate is mounted on a nylon planchet and is covered with an 80 mg/cm2 aluminum absorber for low level beta counting. I Chemical yields of strontium and yttrium are determined by gravimetric means.
- 3. Results and Conclusions I
A summary of the analysis results during the report period are listed in Table 2-2. A trend graph of iodine-131 and strontium-90 analyses (including the pre-operational I period through the report period) is shown on Figure 2-13. I
- a. Strontium-89: Although not required by the ODCM, a total of forty-eight (48) milk samples were analyzed for strontium-89 during the report period. Strontium-89 was not detected in any of the twenty-eight (28) indicator samples, nor was it detected in I
any of the twenty (20) control samples.
- b. Strontium-90: Although not required by the ODCM, a total of forty-eight (48) milk I
samples were analyzed for strontium-90 during the report period. Strontium-90 was detected in eight of twenty-eight (8 of 28) indicator samples and ten of twenty (1 O of I I 2-50 I
I Beaver Valley Power Station R1LA9.690E 2020 Annual Radiological Environmental Operating Report Enclosure 3 I SECTION 2 -ENVIRONMENTAL MONITORING PROGRAM I 20) control samples. The levels detected were attributed to previous nuclear weapons tests and are within the expected range. I c. Gamma Spectrometry: A total of forty-eight (48) milk samples were analyzed by gamma spectrometry during the report period. Naturally occurring potassium-40 was I present in twenty-eight of twenty-eight (28 of 28) indicator samples and twenty of twenty (20 of 20) control samples. No other gamma-emitting radionuclides were identified during analysis. I d. Iod_ine-131: A total of forty-eight (48) milk samples were analyzed for iodine-131
- I during the report period. Iodine-131 was not detected in any of the twenty-eight (28) indicator samples, nor was it detected in of the twenty (20) control samples.
I e. Deviations from Required Sampling and Analysis: There was one deviation from the required milk sampling and analysis schedule occurred for the reporting period. I Sufficient milk samples were not available from locations within the 5-mile radius in 2020. The unavailability of milk caused the REMP to not meet the ODCM sample I requirements in l/2-ODC-2.03 and in l/2-ODC-3.03, Attachment Q Table 3.12-1 stating that a minimum of four (4) milk locations shall be sampled. This initiated the ODCM requirement for sampling two (2) additional garden locations based upon the I highest predicted annual average D/Q when milk locations are not available.
- f. Summary: Based on all the analytical results and the comparison to pre-operational I levels, the operation of BVPS did not contribute any measurable increase in radioactivity in the milk during the report period compared to previous years.

- a. Program I
Feedstuff: Although not required by the ODCM, representative samples of feedstuff (cattle feed) are collected monthly from the nearest dairy farm (Brunton Dairy) and analyzed by gamma spectrometry. See Figure 2-17. Foodcrops (leafy vegetables): Foodcrops are collected at garden locations during the growing season. Leafy vegetables (e.g. cabbage) are obtained from Shippingport, Raccoon, Georgetown, and Industry, Pennsylvania. Samples are obtained from two (2) additional locations based upon the highest predicted annual average ground D/Q when milk locations are unavailable. Samples are also obtained from the control location in Weirton, West Virginia. All samples are analyzed for gamma emitters by gamma spectrometry. Samples are also analyzed by radiochemical analysis for I iodine-131. I
- b. Procedures Gamma Emitter Analysis of Foodcrops: Analysis is performed by scanning a dried, I
homogenized sample with a gamma spectrometry system. A high-resolution germanium detector is utilized with this system. Samples of feedstuff and foodcrops are loaded into tare weight 150 or 300 mL plastic bottles or I-liter Marinelli I containers, weighed and the net weight of the sample is determined prior to scanning for gamma emitters.

- 1. Pathways to Man - Calculation Models The radiation doses to man as a result of BVPS operations were calculated for both I
gaseous and liquid effluent pathways using computer software RADEAS which was newly implemented in 2019. The computer software follows Regulatory Guide 1.109 I and site ODCM methodology. Dose factors listed in the ODCM are used to calculate doses from radioactive noble gases in discharge plumes. BVPS effluent data, based on sample analysis were used as the radionuclide activity input. I All batch and continuous gaseous effluent releases were included in the dose assessment calculations. The release activities are based on laboratory analysis. Meteorological data I collected by the BVPS Meteorology System was also used as input to the dose assessment. The usage factors were obtained from the BVPS Final Environmental I Statements or Regulatory Guide 1.109, except when more recent or specific data was available. I All radioactive liquid effluents are released by batch mode after analysis by gamma spectrometry. Each batch is diluted by cooling tower blowdown water prior to discharge into the Ohio River via the main outfall [River Mile 35.0]. The actual data from these I analyses are tabulated and used as the radionuclide source term input to the computer software. The usage factors were obtained from the BVPS Final Environmental I Statements or Regulatory Guide 1.109, except when more recent or specific data was available. I The total doses to an individual were evaluated for all liquid and gaseous effluent pathways. I
- 2. Results of Calculated Dose to Man - Liquid Effluent Releases During the report period, the calculated dose to an individual member of the public from I
liquid effluent releases is presented in Table 2-5. Also shown in the Table 2-7 is a comparison to natural radiation exposure. I I I I 2-62 I

I F. Prevailing Wmds: The prevailing wind direction for ground releases was identified by sh!):WW& *th~, highest D~Q, in the west ~ r . The, prev~g wind direction for elevated I releases was identified by showing the highest D/Q in the east-southeast sector. The REMP properly monitors the environment with air particulate sampling stations in some sectors and I direct radiation 1LDs in all sectors. G. 2020 Dairy Cow & Doe Goat Sampling Locations: The dairy cow sampling locations will I I'CilYUD: at ~ronton Dairy, 3681 Ridge Road, Aliquippa, PA (6.076 mil~s, southeast), and Windsheimer Dairy, 20 Windsheimer Lane, Bmgettstown, PA (10.475 miles, south-southwest). The doe goat sampling location will remain at the Covert Residence, 930 Pine I Street (Route 168), Hookstown, PA (2.131 miles, southwest). H. D/0 for Mikh I Animal Locations: None of the 2020 milch animal sampling locations experienced a >20% increase in D/Q. Therefore, a Special Report per ODCM procedure l/2-ODC-3.03, Attachment R, Control 3.122 Action "a" and/or Action "b" is not required. I L X/0 and D/O for Offsite Dose Determination: A change in methodology for calculating meteorological dispersion {X/Q) and deposition (D/Q) values resulted in some significant I differences (>20% change in a non-conservative direction) that will be addressed in the next ODCM revision. The change in meteorology has no bearing on meeting the requirements of Control 3.12.2 Action "a" and/or Action "b". Therefore, a Special Report per ODCM is not I required. .I J. X/0 and D/O Comparison: There is no adverse trend in D/Q when comparing 2009 to 2020 data to the ODCM default D/Q values. However, several locations had higher X/Q values that were >20% of the OD_CM default values. A comp~on of the annu~ D/Q to ODCM I default D/Q is provided in Table 3-2. 3-2

The vendor laboratory was immediately notified of the failures and was requested to perform re-analysis. The results from the re-analysis for Strontium-90 (water) and Zinc-65 (water) passed the acceptance criteria whereas Strontium-90 (milk) I failed. The re-analysis for Strontium-90 in milk had a yielded ratio of 0.79 and the acceptance criteria is 0.80 - 1.25. The yielded ratio is the percent of the true value of the sample. This result indicated that the Strontium-90 result is biased low for milk, just I below the acceptance criteria. (CR-2020-048 04). The second quarter environmental cross check results indicated that Chromium-51 I (water) failed the acceptance criteria as listed in the NRC Inspection Procedure 84750, 11/14/19, Inspection Guidance 84750-03. The vendor laboratory was immediately 1_ notified of the failure and was requested to perform re-analysis. The result of the re-analysis result passed the acceptance criteria. The vendor laboratory was also notified of the omission oflodine-131 by gamma. The I vendor stated that the I-131 by gamma result was inadvertently left out and going forward the result would be included. I Accordingly, the vendor reviewed the instrument performance/q uality control charts, environmental conditions and data qualification in accordance with their Quality Assurance Manual and performed re-analysis upon request A discussion was held I with the Quality Assurance Manager and human error is to blame for the Chromium-51 failure and result omittance. As for the Chromium-51 failure, a staff member incorrectly typed the result in the reporting system thus alluding to a typographical I error.
