RTL# A9.690E, Page iv Onsite Groundwater Monitoring: H-3 Summary: In 2019, twenty three (23) on-site monitoring wells were sampled in the spring and fall sampling periods. No new wells were installed, nor were any wells retired.

MW-16 was sampled eleven (11) times throughout 2019, 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 water samples were <440 pCi/L. See Enclosure 2, Page xvii for additional details.

Onsite Spills: There were no onsite spills >100 gallons.

Decommissioning File Update: There were no items added to the site decommissioning files in accordance with 10CFR50.75(g).

Abnormal Liquid Releases: There were no abnormal liquid releases.

Abnormal Gaseous Releases: There-were no abnormal gaseous releases.

Liquid Radwaste Treatment System: The site operated via a shared Liquid Radwaste Treatment System, 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.

Gaseous Radwaste Treatment System: The site operated via a shared Gaseous Radwaste Treatment System, even though each Unit has its own charcoal delay beds and storage/decay tanks. Shared operation 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 (elevated pathway) are assigned to Unit 1.

RTL# A9.690E, Page v Lower Limits of Detectability (LLD): All a-priori calculated LLD met the minimum requirements specified in the ODCM.

Effluent Monitoring Channels Inoperable >30 Days: There was one (1) Effluent Monitoring Instrumentation Channels not returned to Operable status within 30 days.

ODCM Surveillance Deficiencies: There were five (5) instances of ODCM Surveillance Deficiencies.

ODCM Changes: There were two (2) changes made to the ODCM.

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.

Carbon-14 Dose Assessment: Carbon-14 dose was calculated using Electric Power Research lnsititue (EPRI) & Regulatory Guide 1.109 calculation methods and the default ODCM receptor. The highest organ doses were to the bone (child). Details ofthe dose assessment due to releases of Carbon-14 in gaseous effluents are provided in Attachment 3 of this report.

RTL# A9.690E, Page xii Gaseous Release Activity (Tritium): The following graph provides a comparison of total gaseous tritium discharged from the site from 1976 to present. 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.

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.

2000 I 20000 Tritium (H-3) Summary In 2019, twenty three (23) on-site monitoring wells were sampled in the spring and fall sampling periods. No new wells were installed, nor were any wells retired. MW-16 was sampled eleven (11) times, two (2) of which were included in the yearly biannual sampling.

Nineteen (19) wells returned results of less than the pre-operational mean (440 pCi/L) during all sample periods in 2019. Three (3) wells returned results >440 pCi/L, but <2000 pCi/L. One (1) well returned results >2000 pCi/L. No wells exceeded 20,000 pCi/L with the highest concentration recorded as 5580 pCi/L.

The NEl/licensee communication level was reached for MW-125 & MW-12D during 2007. Notification to local, state & federal agencies was performed on 10/08/07 Additional communication for new well results was performed on 09/08/10 for those new wells that exceeded 2000 pCi/L. The newly installed well MW-20D exceeded 2,000 pCi/L on its first sample, but this was expected since the well was installed to monitor the previously identified plume intercepting MW-16. No adverse effect to the offsite environment has been detected at this time, because all offsite groundwater, drinking water and surface water samples were <440 pCi/L. Mitigation activities (catch basin sleeving) to prevent tritiated condensate water from reaching the groundwater were completed 12/17/11.

Extraction well, EW-1, was installed and began operation in October 2013. This equipment captures the tritium plume and it becomes a permitted discharge. Samples are taken weekly to provide the concentration of the discharge. Remediation will continue until the suspected plume is depleted and tritium levels stabilize.

Principal Gamma Emmitter Summary All onsite monitoring wells were sampled during the year, and analyzed for Principal Gamma Emitters. The results showed rio positive indication of Licensed Radioactive Material (LRM) in any of the analyses.

Therefore, grab sample LLD values reflect a different volume (ie; 10 cuft or 2.83E+S cc).

(3) The calculated LLD's are for Unit 2 Detector 7, except those denoted by (1). are from a counter/detector calibration on 2/25/19.

These values are typical for other counter/detectors used for effluent counting at BVPS.

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 ODCM).

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 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.

Form 1/2-ENV-01.05.FOl (page 38 of 39), Rev 5 Beaver Valley Power Station - Units 1 & 2 Annual Radioactive Effluent Release Report Calendar Year - 2019 Table 8 There were four Offsite Dose Calculation Manual Surveillance Deficiencies during this report period.

1) Beaver Valley Representative Sampling (CR #2017"04211) - Carried over from 2017 RTL# A9.690E, Page 20 of 21 It was determined that, due to incorrectly sized nozzles and variations the ventilation stack flows, the effluent monitor sampling skid does not provide representative sampling of particulate isotopes (especially of larger particle sizes) under all normally occurring ventilation conditions at all of Unit 1 pathways and Unit 2 Ventilation Vent and Condensate Polishing Building Vent pathways. This condition was identified and questioned during a Unit 1 sample pump replacement in April 2017. Due to the limited amount of particulate that is released from the site, it does not significantly affect dose or dose rates to the public, nor challenge any regulatory limits (reference CR-2017-04211). Maintenance work for this item was completed in 2019 to ensure representative samping now occurs.

2) Compensatory action for out of service radiation monitor not collected (CR #2019-05978)

Between June 3, 2019 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> and June 14, 2019 0215 hours0.00249 days <br />0.0597 hours <br />3.554894e-4 weeks <br />8.18075e-5 months <br />, compensatory gas grab sampling was not performed when both radiation monitor RM-lVS-109 and backup radiation monitor RM-lVS-1018 were out of service: At the time it was believed that RM-1VS-101B remained in service, however in August a desig'n flaw in RM-lVS-lOlB was discovered that rendered the radiation monitor unable to perform its function. Iodine cartridges and particulate filters were otained during this period and upstream monitor RM-lVS-102 remained in service during the time.

3) Missed ODCM surveillances (CR #2020-01743)

Between the months of April 2019 and February 2020, there were multiple* occasions of five types of ODCM 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.

The specific surveillances were:

SR 4.11.1.3.1, 31-day dose projection for liquid effluents, SR 4.11.4.2.1, 31-day dose projection for gaseous effluents, SR 4.11.2.2.1, cumulativ_e dose contributions from noble gases SR 4.11.2.3.1, cumulative dose contributions from ga*seous releases of particulates and iodines SR 4.11.1.2.1, cumulative dose contributions from liquid effluents,

4) ODCM gaseous tritium sample collected from incorrect monitoring location (CR# 2020-02384)

ODCM required tritium sample for the Unit 11R26 Refueling Outage Containment Purge Permit was collected off the Process Vent (RM-lGW-109) when it should have been collected off of the Ventilation Vent (RM-lVS-109). It was determined that the cause of this error was due to miscommunications between Operations and Chemistry. Activity and dose from the tritium released were able to b.e estimated using local samples from the contaiment building around the same time period.

5) ODCM gaseous tritium sample not collected (CR #2020-02415)

ODCM required tritium sample for the Refueling Outage Containment Vacuum Permit was not collected. Samples could have been taken locally in containment before discharge or from the Process Vent (RM-lGW-109) during discharge. However,due to an error in the permit instructions, there was confusion about the discharge pathway. Activity and dose from the tritium released were able to be estimated using local samples from the contaiment buil_ding during the refueling period.

,I There were two {2) changes made to the ODCM during the report period. See ODCM procedure l/2-0DC-1.01, "ODCM: Index, Matrix and History ODCM Changes" for a complete description of the change and the change justification. A brief description of the change is as follows:

1) Change (44) to the ODCM {Effective April 2019)

<> Procedure 1/2-0DC-l.Ol, "ODCM: Index, Matrix and History of ODCM Changes" (Rev 27)

Updated the History of ODCM changes to include this change and corrected minor typos.

<> Procedure l/2-0DC-2.02, "ODCM: Gaseous Effluents" {Rev 10)

Updated for BV-1 Gaseous Waste Monitor Upgrade - new efficiencies and setpoints. Minor Typos corrected.

<> Procedure l/2-0DC-3.03, "ODCM: Controls for RETS and REMP Progams" (Rev 16)

Updated Attachment D for both Unit 1 and Unit 2 radiation monitor with respect their channel operational tests moving from 31 days to 92 days to support the station and reducing wear on the radiation monitors.

2) Change (45) to the ODCM (Effective July 2019)

<> Procedure l/2-0DC-1.01, "ODCM: Index, Matrix and History of ODCM Changes" {Rev 28)

Updated the History of ODCM changes to include this change and revised references to voided forms. Removed Controls from Attachment C Table F:3b associated with Condensate Polishing effluents.

<> Procedure l/2-0DC-2.02, "ODCM: Gaseous Effluents" (Rev 11)

Designed source of radioactive materials was removed from the Condensate Polishing Building, therefore Condensate Polishing Ventilation is removed as a significant effluent pathway; removed continuous surveillance requirements (sampling and monitoring) for this pathway. Controls for Condensate Polishing radation monitor 2HVS-RQ112 are removed and therefore all references to Condensate Polishing are treated the same as the Turbine Building Ventilation. A correction was made to the variables (X/Q)v in equations [2.2-1] and [2.2-2] because it should reference ground releases, not elevated. The turbine buildi.ng variable was added to equation [2.3-7] and [2.3-8]

because it was missing. A clarifying statement was added for carbon-14 dose methodology.

<> Procedure 1/2-0DC-.3.Q3, "ODCM: Controls for RETS and REMP Progams" {Rev 17)

Removed Condensate Polishing as a significant effluent pathway at Unit 2 and removed associated sampling and monitoring requirements due to the design change which removed radioactive source terms. Additionally, references to RAS Pumps and associated flow rate devices were changed to generic sampling equipment.

The Meteorological Data Recovery for the calendar year 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). The actual Meteorological Data Recovery is shown in the following table:

PERCENT RECOVERY OF INDIVIDUAL METEOROLOGICAL PARAMETERS 99.3% = Wind Speed 35'

- 99.3% = Wind Speed 150' 99.3% = Wind Speed 500' 100.0% = Wind Direction 35' 100.0% = Wind Direction 150' 100.0% = Wind Direction 500' 100.0% = Delta Temperature (150' - 35' ) 1P 100.0% = Delta Temperature (500' - 35' ) 2P 100.0% = Temperature 35' 100.0% = Precipitation 99.8% = Average Recovery of Individual Meteorological Parameters PERCENT RECOVERY OF COMPOSITE VARIABLES 99.3% = Wind Speed 35', Wind Direction 35', Delta Temperature 1P 99.3% = Wind Speed 150', Wind Direction 150', Delta Temperature 1P 99.3% = Wind Speed 500', Wind Direction 500', Delta Temperature 2P 99.7% = Average Recovery of Composite Variables Hourly meteorological data is not provided for specific periods of Abnormal Gaseous Release during the calendar quarters (as indicated in Regulatory Guide 1.21), for the following reasons:

1) All routine Gaseous Relea_ses for the calendar year were determined to be within design objectives, where as, the ODCM Dose Limits and the ODCM Dose Rate Limits are considered to be the design objectives.

2) There were no Abnormal Gaseous Releases during the calendar year, no design objectives were exceeded.

Gaseous doses from carbon-14 were calculated in accordance with EPRI and Regulatory Guide 1.109 methodology. Other considerations were made in the calculations; daylight hours and growing season.

Liquid effluent release doses are considered to be insignificant and are not included in this report. This report does not address the amount of carbon-14 disposed of in shipments of solid waste and irradiated fuel. The term "other" discussed below refers to liver, total body, thyroid, kidney, lung and GI. Doses for these organs are assumed to be equal.

The receptor chosen was selected based upon the default ODCM receptor - NW 1432 meters {0.89 miles). It is assumed that only vegetation and inhalation exposure pathways are available.

The maximum bounding dose to a member of the public resulting from atmospheric C-14 releases from Unit 1 was determined to be less than 2.50 mrem to the bone and less than 1.06 mrem to all other organs.

The maximum bounding dose to a member of the public resulting from atmospheric C-14 releases from Unit 2 was determined to be less than 2.48 mrem to the bone and less than 1.06 mrem to all other organs.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report EXECUTIVE

SUMMARY

and INDEX Report Overview:

RTL A9.690E 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, fish, food crops, teed 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 accordai:ice with the Radiological Effluent 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):

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 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.

Description of Operational REMP (1976-Present):

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 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:

11 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 levels, or radiation present due t9 causes other than BVPS operation, can thus be compared to the environment surrounding the BVPS site. During the rep01i period, two hundred fifty-eight (258) 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 2-2 of this report.

c;i Indicator Samples: Indicator samples are collected to determine the radiological impact of BVPS operation in the environment. These samples are collected from various locations near JI I I

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report EXECUTIVE

SUMMARY

and INDEX RTL A9.690E 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 period, one thousand five hundred nineteen (1,519) analyses were performed on samples collected from seventy-seven (77) indicator locations. In addition, five hundred seventeen (517) analyses were completed for TLDs at the indicator locations. Results of the analyses from the indicator locations are also summarized in Table 2-2 of this report.

o Comparisons: Current analysis results from the indicator samples were compared to both current control sample values and the pre-operational baseline to determine if changes in radioactivity levels were attributable to BVPS operation.

Determination of Environmental Impact e

2019 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 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 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 Detection (LLD).

Ii Airborne Exposure Pathway: This ODCM required pathway was evaluated via sampling of airborne radioiodine and airborn_e particulates. The results during this report period were similar to previous years.

There was no notable increase in natural products and no detectable fission products or other radionuclides in the airborne particulate media d!-!ring the year attributed to effluent releases from BVPS.

e 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 years.

e Ingestion Exposure Pathway: This ODCM required pathway was evaluated via sampling of milk, fish, and foodcrops (leafy vegetables).

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 IV

SUMMARY

and INDEX RTL A9.. 690E indicated positive results for naturally occurring potassium-40 at average environmental levels.

The fish samples indicated below LLD levels in each of the sample analyses.

Foodcrop (leafy vegetation) samples indicated naturally occurring potassium-40 at average environmental levels.

o Waterborne Exposure Pathway: This ODCM pathway was evaluated via samples of drinking water, ground (well) water, surface (river) water and river sediment.

Water samples were analyzed for tritium and gamma-emitting radionuclides. Tritium was 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 and was not due to liquid effluent releases from BVPS.

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, 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-60 was identified in some of the samples that were obtained at the shorelines of the BVPS Main Outfall Facility. This is not unusual because the BVPS site discharges cobalt-60 in liquid waste effluents. The 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 fo1ih in the ODCM.

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 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 ( l) well in Hookstown, PA and one (I) well in Georgetown, PA.

Each ground water sample was analyzed for tritium and is analyzed by gamma spectrometry.

SUMMARY

and INDEX RTL A9.690E Supplemental Sample Sites: REMP includes supplemental sampling sites in addition to the required sites set forth in the ODCM. The supplemental sites include three (3) air sampling sites, one (I) sediment site, one (I) milk animal feedstuff site, and five (5) soil sampling sites.

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 RAD EAS which was newly implemented in 2019. The computer software follows 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 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 0.0238 mrem whereas the gaseous effluent release was 0.450 mrem. The incremental increase in total body dose from the operation of BVPS - Unit l and 2, is 0.0765% of the annual radiation exposure.

Figure i-1 illustrates the individual dose from BVPS effluents and natural background dose.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report EXECUTIVE

SUMMARY

and INDEX RTL A9.690E Summary: During the report period, radioactive effluent releases from the BVPS site did 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, 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 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 LLD.

Inter-laboratory Comparison Programs:

Split Sample Program: BVPS shared split samples with the Pennsylvania Department of Environmental Protection (PADEP) in support of their nuclear power plant monitoring program. The shared media and number of locations were typically comprised of milk (2),

surface water (2), river sediment (I), fish (I), foodcrops (2), co-located air particulate/air iodine (4), and TLD (24). The split sample program was coordinated by the state, and the results are not provided with this report.

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 charcoal cartridge samples. All one hundred eight ( I 08) analyses performed by the contactor laboratory on the spiked samples met the NRC comparison criteria.

Special Reports:

Since no reporting levels were exceeded during 2019, no Special Reports were required. A Special Report shall be submitted to the NRC when (I) levels of radioactivity in an environmental sampling medium exceeds the limits specified in ODCM procedure l/2-0DC-3.03, Attachment Q Table 3.12-2, and when (2) the results of the following calculation are 2'.:_I.O (for calculations performed when more than one radionuclide is detected in the sampling medium):

(\\)

Prevailing Winds: The prevailing wind direction for ground releases was identified by showing the highest deposition parameters (D/Q) in the west (W) sector. The prevailing wind direction for elevated releases was identified by showing the highest D/Q in the east-southeast (ESE) sector.

The REMP properly monitors the environment with air particulate sampling stations in some sectors and direct radiation TLDs in all sectors.

6l 2019 Dairy Cow & Doe Goat Sampling Locations: The dairy cow sampling locations have not changed in 2019. The locations remain at Brunton Dairy, 3 681 Ridge Road, Aliquippa, PA (6.067 miles, southeast), and Windsheimer Dairy, 20 Windsheimer Lane, Burgettstown, PA (10.475 miles, south-southwest). The doe goat sampling location has not changed since the previous census and remains at the Covert Residence, 930 Pine Street (Route 168), Hookstown, PA (2.131 miles, southwest).

D/0 for Milch Animal Locations: The 2019 milch animal sampling locations have not experienced a >20% increase in D/Q.. Therefore, a Special Report per ODCM Control 3.12.2 Action "a" and/or Action "b" is not required.

D/0 for Offsite Dose Determination: There is no adverse effect on the current ODCM methodology used for offsite dose determination from effluent releases. Specifically, the analysis of D/Q did not yield any valid locations where the offsite dose could have VIII

SUMMARY

and INDEX RTL A9.690E increased >20%* of the offsite dose previously calculated using current ODCM methodology. Therefore, a Special Report per ODCM Control 3.12.2 Action "a" and/or Action "b" is not required.

e D/0 Historical Trend Comparison: There is no adverse trend in 0/Q when comparing 2009 to 2019 data to the ODCM default 0/Q values. This validates that there is no adverse effect on the current ODCM methodology used for offsite dose determination from effluent releases. Specifically, the analysis of D/Q did not yield any valid locations where the offsite dose could have increased >20% of the offsite dose previously calculated using current ODCM methodology. Therefore, a change in ODCM Receptor location and/or a change to meteorology at the current ODCM Receptor location is not required.

The 2019 Land Use Census results indicate that no significant changes are required in the current Radiological Environmental Monitoring Program or to its methodology.

Deviations, Changes and Adjustments to the Normal Sampling Program I,)

Deviation from Normal Air Particulate & Iodine Sampling and Analysis Schedule:

There were five deviations from the required airborne particulate sampling and analysis schedule during the report period.

These issues were documented in the following Condition Reports: CR-2019-01917, CR-2019-01918, CR-2019-09361, CR-2020-02941 and CR-2020-01495.

During the sampling period of 02/18/ 19 - 02/25/19, REMP Air Particulate and Iodine sampling station at Brunton's Dairy in Aliquippa (Site No. 27, 6.16 miles SE) was found to be out of service. The cause was a loss of local power due to wind storms during the weekend. All air station components were checked, and no issues were identified. The station returned to operation on 02/27/2019 when local power was restored. The sample station was out of service for approximately 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> as reported by the REMP technician.

Backtracking the power conduit to the Duquesne Light Company Substation revealed that one of the substation's internal fuses had blown. The air sampler's timer should have read 168:40 hours, however it instead read 84: 18, indicating a total power loss of approximately 84:22 hours, beginning at 2046 on 10/31/19. (CR-2019-0936 I)

During the sampling period of 07 /08/ I 9 - 07 /15/19, REMP Air Particulate and Iodine sampling station at Brunton's Dairy in Aliquippa (Site No. 27, 6.16 miles SE) was found to be out of service. The cause was a tripped safety-overload fuse due to a thunderstorm. The station returned to operation on 07/11/2019.

As found data for a piece of M&TE was out of calibration limits when it was returned for recalibration as documented in CR-2020-01495. The air flow at the REMP Air sample stations was lower than expected and therefore the sample results calculated using the lower than expected air flow were corrected. The REMP Air sample stations have all been calibrated using an Air Flow Measuring Device that is currently within calibration.

Deviation from Normal Direct Radiation Monitoring: There were two deviations from the required direct radiation monitoring schedule during the report period.

During the second quarter changeout, the REMP Technician noticed that Station #91 (Pine Grove and Doyle Roads) was missing both TLDs; whereas, Station 94 (McCleary & Pole Cat Hollow Road) was missing one of the two TLDs. (CR-2020-02942) 8 Deviation from Normal Surface and Drinking Water Sampling and Analysis Schedule:

There was one deviation from the ODCM required water sampling and analysis schedule during the report. During* the sampling period of 03/12/19 - 03/19/19, REMP Surface Water sampling station at East Liverpool Water Authority (Site No. 05, 4.89 miles WNW) was found to be out of service. The initial cause was thought to be a loose. corroded fuse, but upon further investigation it was the minutes timing mechanism. All other sampling components were checked, and no issues were identified. The station was returned to service on 3/22/ 19 when the components were replaced. The sample station was out of service for approximately 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> as reported by the REMP technician. (CR-2019-03557) 0 Deviation from Normal Milk Sampling & Analysis Schedule: There was one deviation from the required milk sampling and analysis schedule occurred for the reporting period.

Sufficient milk samples were not available from locations within the 5-mile radius in 20 I 9.

The unavailability of milk caused the REMP to not meet the ODCM sample requirements in 1/2-0DC-2.03 and in l/2-0DC-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 X

The analysis schedule of 1-131 for both drinking and surface was changed from weekly to biweekly.

Corrections to Previous Radiological Environmental Operating Report(s): There are two corrections to be addressed for the 2018 report. The 2018 Annual Radiological Effluent Operating Report (AREOR), for REMP Air Station activity sample results, has been updated based on the discovery that as found data for a piece of M&TE was out of calibration limits when it was returned for recalibration on 12/31/2019. The 2019 REMP Air Station activity sample results were also revised accordingly. The M&TE was an air flow measuring device used between 10/5/18 and 10/5/19.

BFAFOOOl FLOW, AIR FLOW MEASURING DEVICE (M&TE) MFG/MODEL: RADECO C-812 was documented as being found out of calibration (per Notification 601256096). This issue was documented in the following Condition Report: CR-2020-01495. Upon review of the data for the M&TE issue, it was discovered that a sample with low flow was inadvertently counted in the original 2018 report and is being corrected in Table 2-2.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 1 - }NTRODUCTION A. Radiation Fundamentals RTL A9.690E Radiation is the conveyance of energy through space. For example, heat emanating from a stove is a form of radiation, as are light rays, microwaves, and radio waves. All matter consists of atoms, which are com,prised of 1positively charged particles (protons), negatively charged particles (electrons), and non-charged/neutral particles (neutrons). The relatively large particles (protons and neutrons) are packed tightly together in a cluster at the center of the atom called the nucleus, while the smaller particles (electrons) orbit around the nucleus.

In an electrically neutral atom, the negative charges of the electrons are balanced by the positive charges of the protons. Due to their dissimilar charges, the protons and electrons have a strong attraction for each other. This holds the atom together. Other attractive forces between the protons and neutrons keep the densely packed protons from repelling each other and prevent the nucleus from breaking apart.

B. Radiation and Radioactivity The following provides an alphabetical glossary of tenns associated with radiation, radioactivity, and the radioactive decay process. The terms discussed include alpha particles, beta particles, gamma rays, genetic effects, half-life, ionization, isotopes, neutrons, radiation, radioactive decay, radionuclides and somatic effects.

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 electrical charge of +2. Alpha particles are 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 size, an alpha particle usually does not 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 pmiicles.

Beta Particles: Beta particles are very small, and comparatively fast particles, traveling at speeds near the speed of light (186,000 miles per second). Beta particles have an electrical charge of either + I or -1. Because they are so small and have a low charge, they do not 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 wood.

1 -* l

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 1 - INTRODUCTION RTL A9.690E Gamma Rays: Gamma rays are pure energy and travel at the speed of light. They have no 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 vanishes.

The range of a gamma ray in air varies, depending on the ray's energy and interactions. Very high-energy gamma 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 material for gamma radiation because of its density. Several inches of lead or concrete may be needed to effectively shield gamma rays.

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.

Half-life: The length of time an atom remains radioactive is defined in terms of half-life, 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 hc1-ve infrequent emissions have a long half-life, where as, radionuclides that have more frequent emissions have a short half-life.

Ionization: Through interactions with atoms, alpha, beta, and gamma radiation lose their 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 atom has the same number 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 removed, an ion is formed. Ionization is one of the processes that may result in damage to biological systems.

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 chemical identity.

For instance, all atoms with one proton are hydrogen atoms, and all atoms with eight protons are oxygen atoms. 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 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 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-I 31, cesium-137, and cobalt-60.

However, neutrons are not of environmental concern since the neutron source at nuclear power stations is sealed within the containment building. Because neutrons have no charge, they are able to pass very close to the nuclei of the material through which they are

. traveling. As a result, neutrons may be captured by one of these nuclei or they may be deflected.* When deflected, the neutron loses 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 of the material through which it is traveling and is called a thermal neutron. In comparison, fast neutrons are much more energetic than thermal neutrons and have greater potential for causing damage to the material through which they travel. Fast neutrons can have from 200 thousand to 200 million times the energy of thermal neutrons.

Neutron shielding is designed to slow fast neutrons and absorb thermal neutrons. Neutron shielding materials commonly used to slow neutro-ns down are water or polyethylene. The shield is then completed with a material such as cadmium, to absorb the now thennal neutrons. Concrete is also used to form an effective neutron shield because* it contains water molecules and can be easily molded around odd shapes.

Radiation: This is the conveyance of energy through space. For instance, heat emanating 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 radiation. Electromagnetic radiation is energy with. no measurable mass that travels with a wave-like motion through space.

Included in this category are gamma rays and x-rays.

Particulate radiation consists of tiny, fast moving particles which, if unhindered, travel in a straight line through space-. The three types of particulate radiation of concern to us are alpha particles, which are made up of 2 protons and 2 neutrons; beta particles, which are essentially free electrons; and neutrons. The properties of these types of radiation will be described more fully in the Range and Shielding section.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 1 - INTRODUCTION RTL A9.690E Radioactive Decay: Radioactive atoms, over time, wi 11 reach a stable, non-radioactive state through a process known as radioactive decay, which is the release of energy from an atom through the emission of ionizing radiation.

Radioactive atoms may decay directly to a stable state or may go through a series of decay stages, called a radioactive decay series, and produce several daughter products that eventually result in a stable atom. The loss of energy through radioactive decay may transform the atom into a chemically different element. For example, when uranium-238 decays, it emits an alpha particle and, as a result, the atom loses 2 protons and 2 neutrons. Since the number of protons in the nucleus of an atom determines its chemical identity, then when the uranium-238 atom loses the 2 protons and 2 neutrons, it is transformed into an atom of thorium-234. Thorium-234 is one of the 14 successive daughter products of uranium-238. Radon is another daughter product, and the decay 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. The information provided in the upper portion of each block is the isotope name, while the information provided in the lower portion of each block is the half-life.

Ii Ii Beaver Valley Power Station 2019 Annual Radiological Environmenfal Operating Report SECTION 1 - INTRODUCTION RTL A9.690E Somatic Effects: The effects of ionizing radiation develop in the directly exposed individual, including an unborn child. Somatic effects can be divided further into acute and chronic effects. Acute effects develop shortly after exposure to large amount of radiation. Chronic effects are a result of exposure to radiation over an extended period of time.

C.

• Units of Measurement Activity (Curie): This relates the number of atoms in a sample that disintegrate (decay) per unit of time. Each time an atom disintegrates, radiation is emitted. The curie (Ci) is the unit used to describe the activity of a material and indicates the rate.at which the atoms of a radioactive substance are decaying. One curie indicates the disintegration of 3 7 billion atoms per second. A curie is a unit of activity, not a quantity of material. Thus, the amount of material required to produce one curie varies. A smaller unit of the curie is used when discussing the low concentrations of radioactivity detected in environmental samples. For instance, the picocurie (pCi) represents one trillionth of a curie.

Absorbed Dose (rad): This is a term used to describe the radiation energy absorbed by any material exposed to ionizing radiation and can be used 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 00 erg/g). 'Fhe rate of absorbed dose is usually given in rad/hr. The rad is not used to quantify biological damage caused by ionizing radiation.

Dose Equivalent (rem): Biological damage due to alpha, beta, gamma and neutron radiation may result from ionizing r,adiation. Some types of radiation, especially alpha particles, cause dense local ionization and can result in up to 20 times the amount of biological damage for the same energy imparted as do gamma or x-rays. Therefore, a quality factor must be applied to account for the different ionizing capabilities of various types of ionizi1ig radiation. When the quality factor is multiplied by the absorbed dose (rad) the result is the dose equivalent.

Dose equivalent is an estimate of the possible biological damage resulting 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 equivalent (rem) uses the quality factor for alpha radiation, which is equal to 20. Thus, I rad of alpha radiation is equal to 20 rem. Since beta and gamma radiation each have a quality factor of l, then I rad of either beta or gamma radiation is equal to I rem. Neutrons have a quality factor ranging from 2 to I 0. In 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.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 1 - INTRODUCTION D. Lower Limit of Detection

• RTL A9.690E The Lower Limit of Detection (LLD) for environmental samples is a calculated value that

.represents an a-priori (before-the-fact) limit for the smallest concentration (i.e.; pCi per unit mass or volume) 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 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 yield, radioactive decay constant, and elapsed time between sample collection and time of counting.

E. Scope and Objectives of REMP The environmental program consists of environmental monitoring for radioactivity in the vicinity of BVPS. Environmental sampling and analyses include air, water, milk, vegetation, river sediments, fish, and ambient radiation levels in areas surrounding the site. The results of these media are assessed to determine impacts of the plant operation on the environment.

The AREOR for BVPS summarizes REMP conducted by the licensee during the report period.

F.

Description of the Beaver Valley Site BVPS is located on the south bank of the Ohiq River in the Borough of Shippingport, Beaver County, Pennsylvania, on a 453 acre tract of land. The site is approximately one mile from 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.

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 population of approximately 2,635 as determined from the 20 IO U.S. Census.

The site lies in a valley along the Ohio River. lt extends from the river (elevation 665 feet 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 level.

BVPS is on the Ohio River at river mile 34.8, a location on the New Cumberland Pool that is 3.1 river miles downstream from Montgomery Lock and Dam, and 19.6 miles upstream from l - 6 I

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 1 - !NTRODUCTION RTL A9.690E New Cumberland Lock and Dam. The Pennsylvania-Ohio-West Virginia border is located 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 -

Water Resources Engineering) at the New Cumberland Dam ranged from 9,856 cubic feet

• per second (minimum monthly average) to 241,265 cubic feet per second (maximum monthly average). The mean flow duririg the report period was approximately 52,549 cubic 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 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.

The climate of the area may be classified as humid continental. The predominant wind 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 48.9 inches.

The average mean temperature during the report period was 48.8° Fahrenheit."

The basic features of the Beaver Valley Power Station Units l and 2 are tabulated below:

Beaver Valley Unit I Beaver Valley Unit 2 Licensed Power Level 2900 - megawatts thermal 2900 - megawatts thermal Type of Power PWR No. of Reactor Coolant Loops 3

No. of Steam Generators & Type 3 - Vertical Steam Used by Main Turbine Saturated PWR 3

3 - Vertical Saturated The BVPS units utilize two separate systems (pri111ary and secondary) for transferring heat from the source (the reactor) to the receiving component (turbine-generator). Because the two systems are isolated from each other, primary and secondary waters do not mix, and radioactivity in the primary system water is nonnally isolated from the secondary system.

Reactor coolant in the primary systern is pumped through the reactor core and steam generators by means of reactor coolant pumps. Heat is transfen-ed from the primary system to the secondary system in the steam generators. The steam is then formed and delivered to 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.

Long-term composite samples are obtained from short-term composite samples at the specified locations.

Composite samples are collected at intervals not exceeding 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

Searight Dairy is no longer operational.

Milk samples are collected biweekly when animals are grazing. The milk samples are collected monthly at other times.

The fish samples contain whatever species are available.

IF adequate sample size is available, THEN the sample is separated according to species, and compositing will provide one sample of each species.

IF adequate sample size is not available, THEN separation by species is not practical.

Therefore, edible parts of all fish in the sample are mixed to provide one sample.

Composite samples are obtained by collecting an aliquot at intervals not exceeding 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at location 2.1. In December of 2016, location 2.1 was closed. The water treatment plant operator at location 5 obtains the weekly grab sample from the daily composite grab samples. In December of 2016, location 5 was transitioned to a composite sample to replace location 2.1.

For location 49A, the weekly grab sample is obtained by a field technician.

Two (2) TLDs are collected quarterly from each monitoring location.

I ODCM procedure 1/2-0DC-3.03, Attachment Q, Table 3.12-1 requires three (3) dairies to be selected on basis of highest potential thyroid dose using milch census data. See Section 2-E of this report (Monitoring of Local Cow's Milk) for specific locations sampled.

Three (3) garden locations required by 1/2-0DC-2.03, Attachment A Table 3.0-1; Sites designated by 1/2-0DC-2.03 Attachment B Figure 3.0-5. Sampling locations may be altered by the REMP Administrator a_t any time based on availability.

When there are not enough milk sample locations available to meet the ODCM requirements, three (3) different types of broad leaf vegetation are to be sampled at each of two (2) indicator locations based on the highest predicted annual average ground D/Q (as determined from the previous year's Land Use Census results), in addition to those samples described in Note (1).

Three (3) different types of broad leaf vegetation shall also be sampled at one (1) control location when in this condition.

2. Summary of Results RTL A9.690E All results of this monitoring program are summarized in Table 2-2.

This table is prepared in the format specified by the NRC via the Branch Technical Position in NUREG-1301, and in accordance with Beaver Valley Power Station ODCM. Summaries of results of analysis of each media are discussed in Sections 2-B through 2-H and an assessment of radiation doses are given in Section 2-I. Table 2-3 summarizes BVPS pre-operational ranges for the various sampling media during the years 1974 and 1975.

Comparisons of pre-operational data with operational data indicate the ranges of values are generally)n good agreement for both periods of time.

Activity detected was attributed to naturally occurring radionuclides, BVPS effluents, previous nuclear weapons tests and/or to the normal statistical fluctuation for activities near the LLD.

The conclusion from all program data is that the operation of BVPS has resulted in no significant changes to the environment.

3. Quality Control Program The Quality Control Program implemented by BVPS to assure reliable performance by the contractor and the supporting QC data are presented and discussed in Section 4 of this report.

4.

• Program Changes No program changes were made in 2019. The 2017 changes will remain in the repo1i for reference. In January 2017, REMP sampling changes were made to remove non-ODCM samples, and they are as follows; two air particulate and radioiodine locations, two groundwater locations, one sediment location, three precipitation locations, and five soil locations. Additionally, the frequency of drinking water analysis was changed to biweekly, surface water analysis #49A was changed to biweekly, and soil sample collection was changed to quinquennial.

Air. flow 1s generally from the southwest in summer and from the northwest in the winter.

2. Air Sampling Program and Analytical Techniques

a.

Program 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 Table 2-1 and shown on a map in Figure 2-1.

Samples are collected at each of these stations by continuously drawir\\.g two cubic 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, while the charcoal cartridge is used for collection of radioiodine.

Samples are collected on a weekly basis.

The charcoal cartridge is used in the weekly analysis of airborne iodine-13 1. 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 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 background counting system.

b. Procedures Gross Beta Analysis of Filter Paper: Analysis is performed by placing the glass fiber filter paper from the weekly air sample in a 2-inch planchet followed by analysis in a low background, gas flow proportional counter.

Gamma Emitter Analysis of Filter Paper: Analysis is performed by stacking all of the glass fiber filter papers collected from each monitoring station during the quarter and scanning the composite on a high-resolution germanium gamma spectrometer.

Iodine-131 Analysis of Charcoal Cartridge: Analysis is performed by a gamma scan of each charcoal cartridge.

3. Results and Conclusions A summary of data is presented in Table 2-2.

a. Airborne Radioactive Particulates RTL A9.690E Gross Beta: A total of four hundred fourteen ( 414) 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 in air particulates.

Gamma 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 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 period) is shown on Figure 2-2.

Deviations from Required Sampling and Analysis Schedule: There were five deviations from the required airborne particulate sampling and analysis schedule during the report period.

During the sampling period of 02/ l 8/ 19 - 02/25/ l 9, REMP Air Particulate and Iodine sampling station at Old Meyer Farm in Hookstown (Site No. 13, 1.49 miles SW) was found to be out of service. The cause was a loss of local power due to wind storms during the weekend. All air station components were checked, and no issues were identified. Restoration of power was performed by Duquesne Light Company. Power was restored on 03/11/2019 at 12:27. The station was out of service for 349 hours0.00404 days <br />0.0969 hours <br />5.770503e-4 weeks <br />1.327945e-4 months <br />.

During inspection of the #51 Aliquippa Substation REMP air sampler, it was discovered that the pump, totalizer, and fan were all without power. Initial

• investigation revealed that the fuses in the pump, totalizer, and exterior power supply box were all present and all components owned and operated by B VPS were functional, which was confirmed by a Duquesne Light Company escort also present.

Backtracking the power conduit to the Duquesne Light Company Substation revealed that one of the substation's internal fuses had blown. The air sampler's timer should have read 168:40 hours, however it instead read 84: 18, indicating a total power loss of approximately 84:22 hours, beginning at 2046 on 10/31/19. (CR-2019-09361).

As found data for a piece of M&TE was out of calibration limits when it was returned for recalibration as documented in CR-2020-01495. The air flow at the REMP Air sample stations was lower than expected and therefore the sample results calculated using the lower than expected air flow were corrected. The REMP Air sample stations have aH been calibrated using an Air Flow Measuring Device that is currently within calibration.

Summary: Based on the analytical results, the operation of BVPS did not contribute any measurable increase in air particulate radioactivity during the report period.

b. Airborne Radioiodine Iodine-13 I: A total of four hundred fourteen ( 414) weekly charcoal filter samples were analyzed for_ iodine-131.

lodine-13 1 was not identified in any of the three hundred sixty-two (362) indicator samples, nor was it identified in any of the fifty-two (52) control samples.

Deviations from Required Sampling and Analysis Schedule: The deviations are the same as described above for airborne particulates.

Summary: Based on analytical results, the operation of BVPS did not contribute any measurable increase in airborne radioiodine during the report period.

I Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM C. Environmental Radiation Monitoring I. Description of Regional Background Radiation and Sources RTL A9.690E Historical information for regional background was obtained from Reuter-Stokes 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/hr to 12 µR/hr.

The sources of background radiation are affected by the terrain in the vicinity of BVPS, 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 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 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 Ambient external radiation levels around the site were measured using TLDs.

During the report period, there were a total of sixty-six (66) environmental TLD locations. This is comprised of forty-four ( 44) off site locations, along with twenty-two (22) 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.

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 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 holder that contains two (2) TLDs at each location.

2-28

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2-ENVIRONMENTAL MONITORING PROGRAM

3. Results and Conclusions RTL A9.690E 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 17.2 mR at the sixty-six (66) indicator locations, and 19.8 mR at the control location. This external exposure rate is comparable to previous years. As expected, there was some variation in external exposure rate among locations and seasons.

Deviations from Required Sampling and Analysis Schedule: There were two deviations from the required direct radiation monitoring schedule during the report period.

During the second quarter changeout, the REMP Technician noticed that Station #91 (Pine Grove and Doyle Roads) was missing both TLDs; whereas, Station 94 (McCleary

& Pole Cat Hollow Road) was missing one of the two TLDs. Yi-ODC-2.03 states that deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons.

l/2-0DC-3.03, ODCM:

Controls for RETS and REMP Programs, only requires that 40 offsite locations be obtained with quarterly collection of at least 2 TLDs at each site. Therefore, BVPS still meets the minimum ODCM requirements by having complete data for 41 of 44 sample stations available. Further actions are not required. (CR-2020-02942)

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 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 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 changes from natural radiation levels, if any, are negligible.

Monitoring of Surface Water, Drinking Water, Groundwater, and Precipitation I. Description of Water Sources 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 National Pollutant Discharge Elimination System (NPDES) discharge points (e.g. cooling tower blowdown, liquid effluent releases, etc.).

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 for cooling purposes.

Groundwater occurs in large volumes in the gravel terraces which lie along the river and diminishes considerably in the bedrock underlying the site. Normal well yields in the bedrock are less than ten ( I 0) gallons per minute (gpm) with occasional wells yielding up to 60 gpm.

In general, the BVPS site experiences cool winters and moderately warm summers with 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 48.9 inches.

2. Sampling and Analytical Techniques

a. Surface (Raw River) Water 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.

Furthermore, Site No. 2.1, Sector 14, Midland - A TI Allegheny Ludlum, the downstream sample, is no longer a viable sample location. A TI permanently closed the Midland facility in 2016. As of December 2016, surface water samples were no 2-33

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2-ENVIRONMENTAL MONITORING PROGRAM RTL A9.690E 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 Allegheny Ludlum.

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 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 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 analyzed for hydrogen-3 (tritium). One automatic river water sampler, located at the A TI-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 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 iodine-13 l. 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 each sample point are shown in Figure 2-5.

b. Drinking Water (Public Supplies)

Drinking water (i.e. treated water) is collected at both the Water Treatment Plant in 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 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 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 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 iodine-1 3 I. Weekly grab samples are then made into monthly composites and are analyzed by gamma spectrometry. Quarterly composites are prepared from each of 2-34 I

The quarterly composites are analyzed for tritium.

Locations of each sample point are shown in Figure 2-5.

c. Groundwater 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 (I) well in Hookstown, PA and one (I) well in Georgetown, PA. Each ground water sample was analyzed for tritium and is analyzed by gamma spectrometry.

d. Precipitation Since these samples are not required, they will no longer be collected as of 2017.

For historical information, precipitation was collected in Shippingport, PA, East Liverpool, OH, and Weirton, WV. Precipitation, when available, was collected each week and combined for quarterly composite samples from the weekly samples. The quarterly composites were analyzed for tritium and gamma emitters.

e. Procedures Gamma Analysis of Drinking Water and Surface Water: The analysis is performed by 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 ODCM, this analysis is also performed on groundwater and precipitation samples.

Tritium Analysis of Drinking Water and Surface Water: The tritium is determined in water samples by liquid scintillation analysis. Although not required by the ODCM, this analysis is also performed on surface water, groundwater and precipitation samples.

lodine-131 Analysis of Drinking Water: The sample is chemically prepared and analyzed with a low-level beta counting system.

Although not required by the ODCM, this analysis is also performed on surface water samples.

3. Results and Conclusions RTL A9.690E A summary of the analysis results of water samples (surface water, drinking water, 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 shown in Figures 2-6 through 2-9.

a. Surface Water Tritium: A total of eight (8) surface water samples were analyzed for tritium during the report period. Tritium was detected in one (1) of the four (4) indicator samples and was not detected in any of the four (4) control samples.

Location 5, East Liverpool Water Department, contained the highest positive value (206 picoCurie /

liter) and was well below the required LLD (2,000 picoCurie / liter).

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 detected in the twelve ( 12) control samples.

lodine-131: Although not required by the ODCM, a total of twenty-six (26) surface water control samples were analyzed for iodine-131 using radiochemical methods during the report period.

Iodine-131 was detected in one of twenty-six ( 1 of 26) 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 location, which is five (5) miles upstream (not influenced by BVPS operation).

Identification of iodine-13 I during the report period was most likely due to medical diagnostic and treatment procedures performed at upstream facilities.

b. Drinking Water Tritium: A total of eight (8) drinking water samples were analyzed for tritium during the report period. Tritium was detected in one ( 1) of the eight (8) indicator samples.

Location 5, East Liverpool Water Department, contained the highest positive value

( 189 picoCurie / liter) and was well below the required LLD (2,000 picoCurie / liter).

Gamma Spectrometry: A total of twenty-four (24) drinking water samples were analyzed by gamma spectrometry during the report period.

Gamma emitting radionuclides were not detected in any of the twenty-four (24) indicator samples.

Iodine-131 was detected in one of the fifty-two (52) indicator samples. Positive results are most likely due to medical diagnostic and treatment procedures performed at upstream facilities, and not caused by BVPS operations.

c. Groundwater Since these samples are not required, they will no longer be collected as of 2017.

d. Precipitation Since these samples are not required, they wi II no longer be collected as of 2017.

e. Deviations from Required Sampling and Analysis Schedule: There was one deviation from the ODCM required water sampling and analysis schedule during the report.

During the sampling period of 03/12/19 - 03/19/19, REMP Surface Water sampling station at East Liverpool Water Authority (Site No. 05, 4.89 miles WNW) was found to be out of service. The initial cause was thought to be a loose corroded fuse, but upon further investigation it was the minutes timing mechanism. All other sampling components were checked, and no issues were identified. The station was returned to service on 3/22/19 when the components were replaced. The sample station was out of service for approximately 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> as reported by the REMP technician. (CR-2019-03557)

f.

Summary: Data from the water sample analyses demonstrate that BVPS did not contribute a significant increase of radioactivity in the local river and drinking water.

The analytical results confirm that the station assessments, prior to authorizing radioactive discharges, are adequate and that the environmental monitoring program is sufficiently sensitive.

Monitoring of Shoreline Stream Sediment and Soil I. Characterization of Shoreline Stream Sediment and Soil RTL A9.690E 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.

2. Sampling Program and Analytical Techniques

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 2-10.

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 ( I 0) to five (5), as well as the sample frequency was revised from once per three years to once every five years.

Soil was last sampled in 2015 and will be 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 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. 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 Gamma Emitter Analysis of Stream Sediment: Analysis is performed in a 300 mL plastic bottle and analyzed by gamma spectrometry.

Gamma Emitter Analysis of Soil: Although not required by the ODCM, analysis is performed in a 300 mL plastic bottle and analyzed by gamma spectrometry.

2-41

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2-ENVIRONMENTAL MONITORING PROGRAM

3. Results and Conclusions RTL A9.690E 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 period) is shown on Figure 2-11 and Figure 2-12.

a. Shoreline Stream Sediment Gamma Spectrometry: A total of four ( 4) sediment samples were analyzed by gamma spectrometry during the report period. Naturally occurring potassium-40, cobalt-60, cesium-I 37, thalliurn-208, bismuth-214, lead-212, lead-214, radium-226 and actinum-228, were detected in two of two (2 of 2) indicator samples and two of two (2 of 2) control samples.

Cesium-137: Radionuclide cesium-137 was identified in two of two (2 of2) indicator samples and two of two (2 of 2) control samples. The results were comparable to that of previous years ( current annual range = 0.06 to 0.10 picocurie / gram) and less than the pre-operational level of 0.4 picocurie / gram. Also, because cesium-137 was 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.

Cobalt-58: Radionuclide cobalt-58 was not identified in the indicator samples (0 of 2) or control samples (0 of 2).

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 results were comparable to previous years (current annual range = 0.11 to 0.31 picocurie / gram), and the data is currently lower than the BVPS Main Outfall Facility pre-operational level of 0.4 picocurie / gram.

Deviations from Required Sampling and Analysis Schedule: There were no deviations from the required sediment sampling and analysis schedule during the report period.

Summary: The identification of cobalt-60 in the shoreline stream sediment near the main outfall facility is not unusual because the plant discharges these radionuclides in liquid effluent releases. The analyses are consistent with discharge data of authorized 2-42 I

Monitoring of Local Cow and Goat Milk I. Description - Milch Animal Locations RTL A9.690E 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.

Detailed field surveys are performed during the grazing season to locate and enumerate 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.

2. Sampling Program and Analytical Techniques

a. Program Cow milk was collected from the one ( l) reference dairy farm within a I 0-mile radius of the BVPS, Brunton Dairy Farm (6.076 miles southeast) and one ( l) control location dairy fann outside of the I 0-mile radius, Windsheimer Dairy Farm ( 10.475 miles south-southwest).

Dairy cow sampling has been performed at Brunton Dairy since 2016, due to the 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).

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 locations are more appropriate.

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 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.

The location of each is shown in Figure 2-8 and described below.

b. Procedure RTL A9.690E lodine-131 Analysis of Milk: The milk samples are chemically prepared, and then analyzed with a low-level beta counting system.

Gamma Emitter Analysis of Milk: This is detennined by gamma spectrometry analysis of a I-liter Marinelli container of milk.

Strontium-90 Analysis of Milk: Although not required by the ODCM, the milk 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 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 of yttrium-90 (Y-90). Yttrium is then precipitated as hydroxide dissolved and re-precipitated as oxalate. The yttrium oxalate is mounted on a nylon planchet and is counted in a low-level beta counter to infer strontium-90 activity.

Strontium-89 Analysis of Milk: Although not required by the ODCM, the strontium-89 activity is determined by precipitating strontium carbonate (SrC03) from the 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.

Chemical yields of strontium and yttrium are determined by gravimetric means.

3. Results and Conclusions 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 period through the report period) is shown on Figure 2-13.

a. Strontium-89: Although not required by the ODCM, a total of fifty-three (53) milk samples were analyzed for strontium-89 during the report period. Strontium-89 was not detected in any of the thirty-three (33) indicator samples, nor was it detected in any of the twenty (20) control samples.

b. Strontium-90: Although not required by the ODCM, a total of fifty-three (53) milk samples were analyzed for strontium-90 during the report period. Strontium-90 was detected in twelve of thirty-three ( 12 of 33) indicator samples and sixteen of twenty 2-49

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM RTL A9.690E

( 16 of 20) control samples. The levels detected were attributed to previous nuclear weapons tests and are within the expected range.

c. Gamma Spectrometry: A total of fifty-three (53) milk samples were analyzed by gamma spectrometry during the report period. Naturally occurring potassium-40 was present in thirty-three of thirty-three (33 of 33) indicator samples and twenty of twenty (20 of 20) control samples. No other gamma-emitting radionuclides were identified during analysis.

d. lodine-131: A total of fifty-three (53) milk samples were analyzed for iodine-131 during the report period. Iodine-131 was not detected in any of the thirty-three (33) indicator samples, nor was it detected in of the twenty (20) control samples.

e. Deviations from Required Sampling and Analysis: There was one deviation from the required milk sampling and analysis schedule occurred for the reporting period.

Sufficient milk samples were not available from locations within the 5-mile radius in 2019. The unavailability of milk caused the REMP to not meet the ODCM sample requirements in l/2-0DC-2.03 and in l/2-0DC-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 highest predicted annual average 0/Q when milk locations are not available.

f.

Summary: Based on all the analytical results and the comparison to pre-operational levels, the operation of BVPS did not contribute any measurable increase m radioactivity in the milk during the report period compared to previous years.

2. Sampling Program and Analytical Techniques

a.

Program RTL A9.690E 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 0/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 iodine-I 31.

b. Procedures Gamma Emitter Analysis of Foodcrops: Analysis is performed by scanning a dried, 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 1-1 iter Marinelli containers, weighed and the net weight of the sample is determined prior to scanning for gamma emitters.

Estimates of Radiation Dose to Man

1. Pathways to Man - Calculation Models RTL A9.690E The radiation doses to man as a result of BVPS operations were calculated for both gaseous 'and (iquid effluent pathways using computer software RADEAS which was newly implemented in 2019. The computer software follows Regulatory Guide 1. I 09 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.

All batch and continuous gaseous effluent releases were included in the dose assessment calculations. The release activities are based on laboratory analysis. Meteorological data '

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 Statements or Regulatory Guide I. I 09, except when more recent or specific data was available.

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 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 Statements or Regulatory Guide 1.109, except when more recent or specific data was available.

The total doses to an indiv'idual were evaluated for all liquid and gaseous effluent pathways.

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 liquid effluent releases is presented in Table 2-5. Also shown in the Table 2-7 is a comparison to natural radiation exposut'e.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 2 - ENVIRONMENTAL MONITORING PROGRAM

3. Results of Calculated Dose to Man - Gaseous Effluent Releases RTL A9.690E During the report period, the calculated dose to an individual member of the public from airborne effluent releases.

Also shown in the Table 2-7 is a comparison to natural radiation exposure. The doses include the contribution of all pathways.

4. Conclusions Based upon the estimated dose to individuals from the natural background radiation exposure in Tables 2-5 and 2-6, the incremental increase in total body dose from the operation of BVPS - Unit 1 and 2, is 0.0765% of the annual radiation exposure.

The calculated doses to the public from the operation of BVPS - Unit 1 and 2, are below ODCM annual limits and resulted in only a small incremental dose to that which area residents already received as a result of natural background. The doses constituted no meaningful risk to the public.

Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report SECTION 3 - LAND USE CENSUS RTL A9.690E H. D/0 for Milch Animal Locations: None of the 20 l 9 milch animal sampling locations experienced a >20% increase in D/Q. Therefore, a Special Report per ODCM procedure I/2-0DC-3.03, Attachment R, Control 3. I 2.2 Action "a" and/or Action "b" was not required.

I.

D/0 for Offsite Dose Determination: There was no adverse effect on the current ODCM methodology used for offsite dose determination from effluent releases. Specifically, the analysis of D/Q did not yield any valid locations where the offsite dose could have increased

>20% of the offsite dose previously calculated using cmTent ODCM methodology.

Therefore, a Special Report per ODCM Control 3.12.2 Action "a" and/or Action "b" is not required.

J. D/0 Historical Comparison: There is no adverse trend in D/Q when comparing 2009 to 2019 data to the ODCM default D/Q values. Annual averages were obtained from 2009 to 2019 to complete a comparison chart to verify the use of the location. This validates that there is no adverse effect on the current ODCM methodology used for offsite dose detennination from effluent releases. Specifically, the analysis of D/Q did not yield any valid locations where the offsite dose could have increased >20% of the offsite dose previously calculated using current ODCM methodology. Therefore, a change in ODCM receptor location and/or a change to meteorology at the current ODCM receptor location are not required.

Split Sample Program {Inter-Laboratory Comparison, Part 1 of 2): BVPS participates in a split sample program with the Pennsylvania Department of Environmental Protection (PADEP) in support of their nuclear power plant monitoring program.

BVPS provided split samples to PADEP throughout the report period. The shared media and number of locations were typically comprised of milk ( l ), surface water (2), sediment

( 1 ), fish (1 ), and food crops (2).

PADEP has co-located continuous air particulate & air iodine sample stations with four (4) of the BVPS locations.

PADEP has co-located TLDs with twenty-four (24) of the BVPS TLDs.

B. Spike Sample Program (Inter-Laboratory Comparison, Part 2 of 2): BVPS participates in a spike sample program with an Independent Laboratory.

This program is used to independently verify sample analyses performed by the BVPS Contractor Laboratory.

Acceptance Criteria: The NRC criteria listed in NRC Inspection Procedure 84750, 11/ 14/19, Inspection Guidance 84 7 50-03 is used as acceptance criteria for comparisons of results of spiked samples between the Contractor Lab and the Independent Lab. These comparisons are performed by dividing the comparison standard (Independent Lab result) by its associated uncertainty to obtain the resolution. The comparison standard value is multiplied by the ratio values obtained from the following table to find the acceptance band for the result to be compared. However, in such cases in which the counting precision of the standard yields a resolution of less than 4, a valid comparison is not practical, and therefore1 not performed.

I Beaver Valley Power Station 2019 Annual Radiological Environmental Operating Report RTL A9.690E SECTION 5 - CORRECTIONS TO PREVIOUS RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT(S)

A. Corrections to Previous Radiological Environmental Operating Report(s): There are two corrections to be addressed for the 2018 report.

The 2018 Annual Radiological Effluent Operating Report (AREOR), for REMP Air Station activity sample results, has been updated based on the discovery that as found data for a piece of M&TE was out of calibration limits when it was returned for recalibration on 12/31/2019. The 2019 REMP Air Station activity sample results were also revised accordingly. The M&TE was an air flow measuring device used between 10/5/18 and 10/5/19. BFAFOOOI FLOW, AIR FLOW MEASURING DEVICE (M&TE)

MFG/MODEL: RADECO C-812 was documented as being found out of calibration (per Notification 601256096).

A review of the M&TE Traveler and form l/2-ENV-03.03.FOI for Air Sarripler Maintenance Calibration identified that this piece of M&TE was used for the following REMP Air Sampler Stations to calibrate the flow thru the air sampler.

REMP Airsample station dates affected:

1. 13: 1 0/3 1/ 18 - 1 1 /2/1 9

1. 27: 10/31/18 - 11/2/19

1. 30: 10/29/18 - 11/4/19

1. 32: 10/29/18 - 11/4/19

1. 46.1: 10/31/18-11/2/19

1. 4 7: 10/3 1/ 18 - 11/4/19

1. 48: 10/31/18 - 11/4/19

1. 51: 10/29/18 - I 1/4/19 The air flow at the REMP Air sample stations was lower than expected and therefore the sample results calculated using the lower than expected air flow were corrected.

The REMP Air sample stations have all been calibrated using an AIR FLOW MEASURING DEVICE that is currently within calibration. (CR-2020-01495)

Upon review of the data for the M&TE issue, it was discovered that a sample with low flow was inadvertently counted in the original 2018 report. REMP Air Particulate and Iodine sampling station at Brunton's Dairy in Aliquippa (Site No. 27, 6.16 miles SE) was found to be out of service thus causing the low flow volume. This value is also being corrected in Table 2-2.

Revised Table 2-2 for the 2018 Air Particulate and Radioiodine is attached.
