SUMMARY

q This report describes the Radiological Environmental Monitoring Program conducted during 1995 in the vicinity of the Beaver Valley Power Station Units 1 and 2. The Radiological Environmental Program consists of off-site monitoring of water, air, river sediments, soils, food pathway samples, and radiation levels in the vicinity of the site. This report discusses the results of this monitoring during 1995.

Duquesne Light Company operates the Beaver Valley Power Station Units 1 and 2 pressurized water reactors as part of the Central Area Power Coordination Group.

The Beaver Valley Power Station Unit 1 operated throughout 1995 except during a refueling outage January 3 through March 8, 1995 and maintenance outages August 19 through August 27 and December 18 through December 26,1995. The high average daily output generated during the year, 840 megawatts net was reached in November 1995 and the total net electrical generation during the year was 5,442,920 megawatt-hours.

Beaver Valley Power Station Unit 2 operated throughout the year except during a refueling outage March 24 through May 9,1995 and a maintenance outage August 13 through August 15, 1995. The highest average daily output generated during the year was 845 megawa'ts net in both November and December 1995 and the total net electrical generation during the year was 6,044,518 megawatt-hours.

In 1995, samples were taken from over 60 sites around Beaver Valley Power Station that included the aquatic, atmospheric and terrestrial environments. More than 3,000 analyses were performed on these samples.

During the year, the radioactive releases from BVPS Units 1 and 2 did not exceed the effluent limits identified in the Beaver Valley Power Station Operating License Technical Specifications /Offsite Dose Calculation Manual (ODCM) for Units 1 and 2.

Based upon the estimated dose to individuals from the natural background radiation exposure, the incremental increase in total body dose to the 50-mile population (4 million people), from the operation of Beaver Valley Power Station - Unit No.1 and No. 2, is less than 0.0003% of the annual background. See Section V.I for specific details. The National Academy of Sciences 1990 BEIR Report shows that the typical j dose to an individual from background (natural radiation exposure including radon) j is 296 mrem per year. l 1

The environmental monitoring program outlined in the Beaver Valley Power Station ,

Operating License Technical Specifications /ODCM for Units 1 and 2 was followed throughout 1995. The results for each media are contained in Section V of this )

report. Examination of effluents and environmental media show that the Beaver Valley Power Station Units 1 and 2 operations have not adversely affected the surrounding environment.

1 Section 1. INTRODUCTION A. Scope and Objectives of the Program The environmental program consists of environmental monitoring for radioactivity in the vicinity of the Beaver Valley Power Station. Environmental sampling and analyses included 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 Annual Radiological Environmental Report for the Beaver Valley Power Station summarizes the radiological environmental program conducted by the Duquesne Light Company in 1995.

B. Description of the Beaver Valley Site The Beaver Valley Power Station is located on the south bank of the Ohio River in the Borough of Shippingport, Beaver County, Pennsylvania, on a 501 acre tract of land. Figure 1-1 is a view of the Beaver Valley Power Station. The site is approximately cz mile from Midland, Pennsylvania; 5 miles from East Liverpool, Ohio; and 25 miles from Pittsburgh, Pennsylvania. Figure 1-2 shows the site location in relation to the princi; , population centers. Population density in the immediate vicinity of the site is relatively low. The population within a 5 mile radius of the plant is approximately 18,000 and the only area within the radius of ,

concentrated population is the Borough of Midland, Pennsylvania, with a population I of approximately 3,500.

The site lies in a valley along the Ohio River, it extends from the river (elevation l 665 feet above wa level) to a ridge along the border south of the Beaver Valley l Power Station at an elevation of 1,160 feet. Plant ground level is approximately 735 feet above sea level.

The Beaver Valley Power Station is on the Ohio River at river mile 34.8, at a location on the New Cumberland Pool that is 3.3 river miles downstream from Montgomery Lock and Dam, and 19.4 miles upstream from New Cumberland Lock and Dam.' The Pennsylvania-Ohio-West Virginia border is located 5.2 river miles downstream from l the site. The river flow is regulated by a series of dams and reservoirs on the l Beaver, Allegheny, Monongahela and Ohio Rivers and their tributaries. Flow ranges from a minimum of approximately 5000 cubic feet per second (CFS) to a maximum of approximately 100,000 CFS The mean annual flow is approximately 25,000 CFS.

Water temperature of the Ohio River varies from 32*F to 84*F, the minimum temperatures occur in January and/or February and maximum temperatures in July and 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. Annual precipitation is approximately 36 inches, typical yearly temperatures vary from approximately - 3*F to 95 F with an annual average temperature of 52.3 F. The predominant wind direction is typically from the southwest in summer and from the northwest in winter.

Duquesne Light Company 1995 Annual Radiciogical Environmental Report The design ratings and basic features of the Beaver Valley ' Power Station Units 1 and 2 are tabulated below:

Beaver Vallev Unit 1 Beaver Vallev Unit 2 Thermal & Elec. Rating (Net MW,) 2660 MW,835 MW, 2660 MW,836 MW, Type of Power PWR PWR No. of Reactor Coolant Loope 3 3 No. of Staam Generators

& Type 3 - Vertical 3 - Vertical Steam Used by Main Turbine Saturated Saturated The units utilize two separate systems (primary 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; therefore, radioactivity in the primary system water is normally isolated from the secondary system. Reactor coolant in the primary system is pumped through the reactor core and steam generators by means of reactor coolant pumps. Heat is given up from the primary system to the secondary system in the steam generators, where steam is 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.

l Duquesne Light Company 1995 Annual Radiological Environmental Report Section 2. RESULTS AND CONCLUSIONS Plant operations at the Beaver Valley Power Station had no adverse effects on the environment as a result of activity at the station during 1995.

The Beaver Valley Power Station Unit 1 operated throughout 1995 except during a refueling outage January 3 through March 8,1995 and maintenance outages August 19 through August 27 and December 18 through December 26,1995. Unit 2 operated throughout the year except during a refueling outage March 24 through May 9,1995 and a maintenance outage August 13 through August 15,1996. During the year, the radioactive releases were below the limits of 10 CFR Part 50, Appendix

1. The releases at Beaver Valley Power Station Units 1 and 2 did not exceed the limiting conditions identified in the Beaver Valley Power Station Operating License Technical Specifications /Offsite Dose Calculation Manual (ODCM) for Units 1 and 2.

The environmental program for 1995 was the same as in 1994 except several changes in dairy locations which were revised as required by the Beaver Valley Technical Specifications /ODCM. (Refer to Table 5-1 for the 1995 Radiological Monitoring Program Outline.)

The Beaver Valley Power Station Technical Specifications /ODCM require sampling of three (3) dairies which have the highest calculated milk pathway potential and one large local dairy. The three dairies are determined from calculations based on the meteorological data and the latest milch animal survey. However, these dairies are frequently small, consisting of as few as one cow or goat. The availability of milk from single cow dairies and revisions due to updated calculations and surveys normally result in sampling of several additional dairies during the year in different sampling periods.

The Environmental Monitoring Program also includes two larger dairies in order to provide continuity in the sampling / analyses program and a control location.

Samples from each of these dairies are obtained in addition to the four dalries required by the Technical Specifications /ODCM. The collection periods associated with each of the locations are provided in the detailed summary of the milk monitoring program of this report (Section 5-E).

Activity detected was attributable to naturally occurring radionuclides, BVPS effluents, previous nuclear weapons tests, medical procedures or to the normal statistical fluctuation for activities near the lower limit of detection (LLD). The positive results attributable to the Beaver Valley Power Station were consistent with station data of authorized radioactive discharges and were within limits permitted by the NRC license.

The results and conclusions for each media of the 1995 Radiological Environmental Monitoring Program are contained in Section 5 of this report. A summary of the 1995 operational environmental data is found in Table 5-2 and a summary of preoperational data (1974-1975) environmental data is found in Table 5-3.

2-2 Section 2. RESULTS AND CONCLUSIONS

Duquesne Light Company 1995 Annual Radiological Environmental Report Section 3. ENVIRONMENTAL MONITORING CONSIDERATIONS A. Environmental Quality Control Program The Quality Control (QC) Program used for the Beaver Valley Environmental Radioactivity Monitoring Program consisted of seven (7) elements. It should be noted that the comparisons made were at very low levels of radioactivity and consequently, the activities at these levels are difficult to measure. See Section 3-B for discussion of comparison criteria for radiochemical determinations. Values in Table 3-2 through Table 3-12 identified with an asterisk (*) do not meet comparison criteria. However, acceptable correlation was achieved in most instances as outlined in the discussions and tables which follow.

1. TLD Monitoring (Duquesne Light Company (DLC) Contractor Laboratory and QC Laboratory)

Thirteen (13) TLDs from the Contractor Laboratory and QC Laboratory are co-located, replaced quarterly and results compared. The average of the Contractor Laboratory and the average of the quality control laboratory agree within i 4.0% of the mean of all results. This is well within the precision of typical TLD Systems. Summary data of the TLD Monitoring Program is provided in Table 3-1.

2. Split Sample Program (DLC Contractor Laboratory - DLC QC Laboratory)

Samples of surface (river) water and drinking water were routinely split and analyzed by the DLC Contractor Laboratory and the DLC QC Laboratory. In addition, samples of other media, such as milk, sediment and feedcrop were also split with the DLC QC Laboratory.

A summary of results of split water samples is provided in Table 3-2 and -

Table 3-3. There were two non-comparisons with surface water. One was for gross beta which was close to comparison and the other was a positive alpha by the QC Laboratory which was reported as LLD by the Contractor Laboratory.

More variability in duplicate samples is expected in surface water due to entrained solids. There were no non-comparisons in all of the drinking water analysis.

Summaries of milk, sediment and feed / food crop split samples are provided in Table 3-4 and Table 3-5. Good overall agreement was obtained with only one non-comparison observed of potassium-40 in feed and non-comparisons in sediment for cobalt-58 and 60 which were close to comparison. Some variation may be expected due to variations in duplicate samples, variations in analytical procedures and in calibration, source type, etc.

[ 3. DLC QC Laboratory Program Spiked samples prepared by DLC QC Laboratory were routinely submitted to the Contractor Laboratory for analysis. Table 3-6 (water) and Table 3-7 (milk) provide data from this portion of the QC Program. See Section 3-B for evaluation of the data.

[ 4. Comparisons of Similar Samples (DLC Contractor Laboratory - DLC QC Laboratory)

[ Duplicate air particulate and charcoal filters (radiolodine) samples were I collected at Location #30 and compared during the year on a weekly basis.

Comparison of particulate and charcoal samples alternated from week to week.

j Duplicate monthly air particulate filters, composited from the weekly air t particulate filters, were analyzed 6 months out of the year for gamma activity.

Duplicate quarterly air particulate filters, composited from the weekly air particulate filters, were analyzed for Sr-89 and Sr-90 activity for each quarter of the year. Table 3-8, Table 3-9 and Table 3-10 provides data for this portion of the QC program.

5. Contractor and QC Laboratory - Internal QC Program The Contractor and QC Laboratory maintained their own QC program which included participation in the Environmental Protection Agency - Environmental f Monitoring Safety Laboratory (EPA - EMSL) Interlaboratory Cross Check Program. This cross check program indicated that the Contractor and QC Laboratory results were in agreement with EPA EMSL. The Contractor data for f 1994 and 1995 is presented with trending graphs from 1981. See Appendix I and ll.
6. Special QC Program (DLC Contractor Laboratory - Independent Laboratory -

{ DLC QC Laboratory)

Low level spiked water and milk samples are prepared by a vendor noted for f supplying quality primary standards with NIST traceability. The " spiked to" values are used for calculating comparison acceptance criteria. The prepared spiked samples are then split between the DLC Contractor Laboratory and the f DLC QC Laboratory. A summary of results of this portion of the QC program is provided in Table 3-11 and Table 3-12. See Section 3-B for evaluation of this data.

7. Pennsylvania Department of Environmental Protection Program The Pennsylvania Department of Environmental Protection (PDEP) also g conducted a surveillance program in the vicinity of the site. Samples of air, B river water, drinking water, sediment, milk, vegetation, fish and radiation monitoring are included in their program. Results were compared quarterly in 1995.

B. Evaluation of the Quality Control Program Data The split and spiked sample program indicates that the Contractor and QC Laboratory are generally performing satisfactorily in accordance with " Criteria for l Comparing Analytical Measurements from NRC Compliance Office." Comparisons between the QC and Contractor laboratories are generally acceptable and j demonstrate a satisfactory performance by the DLC contractor. All media were in agreement in accordance with NRC criteria as listed in Inspection Guidance 84750-03 dated 12/04/90 with the exception of those media in Table 3-2 through l Table 3-12 identified with an asterisk (*). Comparisons are obtained by dividing the comparison standard by its associated uncertainty to obtain the resolution. The standard value is multiplied by the ratio values obtained from the following table to find the acceptance band for the result to be compared. Note that in the case where the counting precision of the standard yields a resolution of less than 4, a comparison cannot be calculated. Resolution Ratio l

  • Contractor Laboratory The Contactor Laboratory had a very satisfactory performance throughout the 1995 QC Laboratory Program. In the Independent Laboratory Program, with reference to the high quality spikes as reported in Table 3-11 and Table 3-12, excellent comparisons were achieved for all milk and water spikes. Re-analysis was required for the last H-3 in water spike of the year and for the strontium in water spike sample of June 13,1995.

In the QC Laboratory spike sample program, as reported in Table 3-6 and Table 3-7 for water and milk, there was one non-comparison. The non-comparison, spike water sample W-123 for gross beta was very close to comparison. The following spike sample for gross beta, W-127, compared. Split drinking water samples for gross beta also compared. Within the Contractor /QC Lab split sample program samples for feed and sediment are particularly subject to sample variability. One non-comparison was noted for pothssium-40 in feed and in sediment cobalt-58 and cobalt-60 were non-comparisons although very close to comparison.

  • Quality Control Laboratory The QC Laboratory hac satisfactory performance within the Independent Laboratory Program. One resJt for 1-131 in milk was slightly out of comparison low in the third quarter and was Milowed by comparison for 1-131 fourth quartur.

Two non-comparisons for Sr-89 occurred in the third quarter, one in water and one in milk. In the fourth quarter, comparisons were achieved for Sr-89 in both milk and water. Based on all available QC program data, the data from the Contractor and QC - Laboratory's internal EPA Interlaboratory Cross Check Program, and comparisons with the PDEP, the Environmental Monitoring Program for 1995 is acceptable with respect to both accuracy and measurement.

Duquesne Light Company 1995 Annual Radiological Environmental Report C. Standard Requirements and Limitations for Radiological and Other Effluents The Beaver Valley Power Station is governed by rules and regulations of the E Federal Government and the Commonwealth of Pennsylvania. Effluent releases are g controlled to ensure that limits set by Federal or State governments are not exceeded. in addition, self-imposed goals have been established to further limit discharges to the environment. Beaver Valley Power Station is subject to regulations which include the Code (J Federal Regulations 10 CFR (Energy), Gaseous Discharge Permits for auxiliary boilers and diesel generators, PA Code - Title 24, Part 1, Ohio River Valley Water Sanitation Commission (ORSANCO) Standards No.1-70 and 2-70, Environmental Protection Agency (EPA), National Pollution Discharge Elimination (NPDES) Permit

              #0025615, and the Beaver Valley Power Station Technical Specifications /ODCM.

D. Reporting Levels A report is required to be submitted to the Nuclear Regulatory Commission when the level of radioactivity in an environmental sampling medium exceeds the limits specified in the Beaver Valley Power Station Technical Specifications /ODCM when averaged over any calendar quarter. Also, when more than one of the radionuclides are detected in the sampling medium, this report shall be submitted if: Concentration (1) Concentration (2)

                                   +                       + . . > 1.0

1. Descriptico of Liquid Effluents at the Beaver Valley Power Station.

l . Most of the water required for the operation of the Beaver Valley station is taken from the Ohio River, and returned to the river, used for makeup to various plant systems, consumed by station personnel, or discharged via a sanitary waste system. In addition, well water and liquid effluents are discharged to the Ohio River using discharge points shown in Figure 4-1. Schematic diagrams of liquid flow paths for the Beaver Valley Power Station are shown in Figure 4-2,

The Beaver Valley Power Station identifies isotopes according to Section 6.8.6a of the Technical Specifications, Appendix C of the ODCM and Regulatory Guide 1.21. Prior to waste gas decay tank batch releases and containment purge releases, an analysis of the principal gamma emitters is performed. The principal gamma emitters include noble gases, lodines, and particulates, g Figure 4-6 shows the gaseous radwaste system at Beaver Valley Power Station. E The environmental gaseous release points also require specific nuclide identification. These points include:

a. Unit 1 Release Points:
1) The Ventilation Vent located on top of the Unit 1 Primary Auxillary Building.
2) The Supplementary Leak Collection and Release System (SLCRS)

Vent located on top of the Unit 1 Containment Building,

b. Unit 2 Release Points;
1) The Ventilation Vent located on top of the Unit 2 Primary Auxiliary Building.
2) The Supplementary Leak Collection and Release System (SLCRS)

Vent located on top of the Unit 2 Containment Building.

3) The Decontamination Building Vent located on top of the Unit 2 Decontamination Building.
4) The Waste Gas Storage Vault Vent located on top of the Uni! 2 Decontamination Building.
5) The Condensate Polishing Building Vent located on top of the Urit 2 Condensate Polishing Building,
c. Unit 1 and Unit 2 shared release point;
1) The Process Vent located on top of the Unit 1 Cooling Tower.

These points are continuously monitored for particulates and gases. Grab samples are obtained on a weekly basis and are analyzed for noble gas gamma emitting isotopes. Grab samples are obtained on a monthly basis and analyzed E for tritium. Weekly continuous samples are obtained on filter paper and charcoal E cartridges. The filter papers are analyzed for particulate gamma emitting isotopes and gross alpha. Composites of the filter papers are analyzed monthly for Sr-89 and Sr-90. The charcoal cartridges are analyzed for 1-131,1-133 and 1-135. Figure 4-7 shows these gaseous release points. 4-10 Section 4. MONITORING EFFLUENTS

2. Atmospheric Effluent Treatment and Sampling )

l Beaver Valley Power Station (Units 1 and 2) i Radioactive gases enter the gaseous waste disposal system from the degasifier vent chiller of the boron recovery system, and are directed to the gaseous waste j charcoal delay subsystem upstream of the overhead gas compressor where the i gas is chilled to condense most of the water vapor. Gases from the degasifier i vent chillers contain primarily hydrogen and water vapor. A small amount of nitrogen and radioisotopes consisting of noble gases, particulates and radiolodines are also present in this system. The overhead gas compressor directs the radioactive gas stream to a gas surge l tank. Gas is periodically transferred from the Unit 1 or Unit 2 surge tank to one l of the three (3) decay tanks at Unit 1 or one of the seven (7) decay tanks at Unit l

2. After the decay tanks are sampled and authorization obtained for discharge, l the flow of the waste gases from the decay tanks (2 scfm) is rapidly diluted with about 1000 scfm of air in order to dilute hydrogen and radioactive effluent j concentration. The gases are then combined with nitrogen purge from the oxygen analyzers. calibration gas from the oxygen analyzers, the main condenser air ejector exhaust, the containment vacuum system exhaust, aerated vents of the vent and drain system, discharge of the overhead gas compressor and the purge from the multi sample point radiation monitor. The mixture is then filtered through one of the gaseous waste disposal filters, each of which consists of a charcoal bed and a high efficiency filter. The filtered gases are then discharged by one of the gaseous waste disposal blowers to the atmosphere via the process vent on the top of the Unit 1 cooling tower. The radioactivity levels of the stream are monitored continuously. l Should the radioactivity release concentration of the stream go above the l allowable setpoint, a signal from the radiation monitor will stop all flow from the -

Unit 1 or Unit 2 decay tanks being discharged. During a shutdown period after the Unit 1 or Unit 2 containment has been sampled and the activity levels determined, purging may commence through the Ventilation Vent located on top of the Auxiliary Building or the Supplementary Leak Collection and Release System (SLCRS) Vent located on top of the Reactor Containment Building or the Process Vent located on top of the Cooling Tower. Most areas in the Unit 1 Auxiliary Building are individually monitored for radioactivity prior to entering the common Ventilation Vent. These individual radiation monitors aid in identifying any sources of contaminated air. The normal exhaust is through the Ventilation Vent effluent pathway. This pathway is monitored continuously by several redundant channels of the Radiation Monitoring System (RMS) and is sampled periodically. However, upon a upper activity alarm, automatic dampers divert the system's exhaust air stream through one of the main filter banks in the Supplementary Leak Collection and Release System (SLCRS) and to the SLCRS Vent effluent pathway. Section 4. MONITORING EFFLUENTS 4-13

Duquesne Light Company 1995 Annual Radiological Environmental Report Areas in the Unit 2 Auxiliary Building (subject to radioactive contamination) are monitored for radioactivity prior to entering the filter banks for the Supplementary Leak Collection and Release System (SLCRS) Vent. This system is sampled periodically for determination of radioactive material and is monitored continuously by other channels of the Digital Radiation Monitoring  ; System (DRMS). l Each Unit 1 and Unit 2 filter bank consists of roughing filters, charcoal filters, and pleated glass fiber type HEPA filters. The roughing filters remove large particulates to prevent excessive pressure drop buildup on the charcoal and HEPA filters. The charcoal filters are effective for radioactive iodine removal and the HEPA filters remove particulates and charcoal fines. Release points for Unit 1 and Unit 2 of e Beaver Valley Power Station are shown in Figure 4-7. Some of these release points discharge small amounts of radioisotopes consisting of noble gases, particulates and radiciodines.

3. Results Gaseous effluents from the Beaver Valley Power Station were released in accordance with conditions noted in Section 6.8.6a of the Technical Specifications and Appendix C of the ODCM. No limits were exceeded. These values have been reported in the Beaver Valley Power Station Annual Radioactive Effluent Release Report for 1995.

C. Solid Waste Disposal During Beaver Valley Power Stat.on normal operations and periodic maintenance, small quantitles of solid radioactive waste materials were generated such as contaminated rags, paper, plastics, filters, spent lon-exchange resins, and miscellaneous tools and equipment. These were disposed of as solid radioactive waste. The services of offsite processors were used to segregato, incinerate, and super-compact the waste. The volume reduced waste was then shipped for disposal. All containers used for packaging, transport, and disposal of radioactive materials met the requirements of the United States Department of Transportation (DOT) and the Nuclear Regulatory Commission (NRC). Shipments offsite were made in accordance with DOT and NRC regulations. Figure 4-8 depicts solid waste handling at the site. During 1995, 1,619 cubic feet of radioactive solid waste were buried offsite. Both units set record low disposal volumes for a refueling outage year. The shipments to the Offsite Processors and Disposal Facility contained a total activity of 500 curies. Industrial solid wastes were collected in portable bins, and removed to an approved offsite burial ground. No burning or burial of wastes was conducted at the Beaver Valley Power Station site.

(e) Composite samples are collected at intervals not exceeding 2 hours. (f) Weekly milk sample from Searight's Dairy is analyzed for I-131 only. (g) Milk samples are collected bi-weekly when animals are in pasture and monthly at other times. [ Assume April- October for grazing season (pasture),] (h) The milk samples from Brunton's and Nicol's Dalries are collected once per month. (i). The fish samples will contain whatever species are available. If the available sample size permits, then the sample will be separated according to species and compositing will provide one sample of each species. If the available size is too small to make separation by species practical, then edible parts of all fish in the sample will be mixed to give one sample. (j) Composite samples are collected at intervals not exceeding 2 hours at locations 49.1 and 2.1. Weekly grab samples are obtained at locations 49 and { 2A. A weekly grab sample is also obtained from ' daily composited grab samples obtained by the water treatment plant operator at location 5. f (k) Two (2) TLDs are collected quarterly and annually from each monitoring location. Additional Notes: Sample points correspond to site numbers shown on maps. All 1-131 analyses are performed within 40 hours of sample collection if possible. ' All air samples are decayed for 72 hours before analyzing for Gross Beta. Section 5. ENVIRONMENTAL MONITORING PROGRAM 5-5

2. Summary of Results All results of this mea'toring program are summarized in Table 5-2. This table is prepared in the format specified by NRC Regulatory Guide 4.8 and in accordance with Beaver Valley Power Station Operating License, (Appendix A, Technical Specifications /ODCM). Summaries of results of analysis of each media are discussed in Sections 5-B through 5-H and an assessment of radiation doses are given in Section 5-l. Table 5-3 summarizes Beaver Valley Power g Station preoperational ranges for the various sampling media during the years l 1974 and 1975. Comparisons of preoperational data with operational data indicate the ranges of values are generally in good agreement for both periods g of time. g Activity detected was attributed to naturally occurring rad;onuclides, BVPS effluents, medical procedures, previous nuclear weapons tests or to the normal statistical fluctuation for activities near the lower limit of detection (LLD).

The conclusion from all program data is that the operation of the Beaver Valley g Power Station has resulted in insignificant changes to the environment. g

3. Quality Control Program The Quality Control Program implemented by Duquesne Light Company to assure reliable performance by the DLC contractor and the supporting QC data are presented ard discussed in Section 3 of this report. The lower limits of detection for various analysis for each media monitored by this program by the DLC Contractor Laboratory are provided in Table 5-2 and in Table 5-4.

Duquesne Light Company 1995 Annual Radiological Environmental Report B. Air Monitoring

1. Characterization of Air and Meteorology The air in the vicinity of the site contains pollutants typical for an indtstrial area.

Air flow is 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 radiolodine and radioactive particulates at each of ten (1) offsite air sampling stations. The locations of these' stations are listed in Table 5-1 and shown on a map in Figure 5-1.

Samples are collected at each of these stations by continuously drawing one cubic foot per minute of atmosphere air through a glass fiber filter and through a charcoal cartridge. The former collects airborne particulates; the latter is for radiolodine sampling. Samples are collected for analysis on a weekly basis. The charcoal is used in the weekly analysis of airborne 1-131. The filters are analyzed each week for gross beta, then composited by station for monthly analysis by gamma spectrometry. They are further composited in a quarterly sample from each station for Sr-89 and Sr-90 analysis. In order to reduce interference from natural radon and thoron radioactivities, all filters are allowed to decay for a few days after collection prior to counting for beta in a low background counting system.

b. Procedures Gross Beta analysis is performed by placing the filter paper from the weekly air sample in a 2" x 1/4" planchet and counting it in a low background, gas flow proportional counter.

Gamma emitters are determined by stacking all the filter papers from each monitoring station collected during the month and scanning this composite on a high resolution germanium gamma spectrometer. Radiciodine (1-131) analysis is performed by a gamma scan of the charcoal in a weekly charcoal cartridge. The activity is referenced to the mid-collection time. l l 5-22 section 5.

l Duquesne Light Company I 1995 Annu:1 Radiological Environmental Report Strontium-89 and Strontium-90 activities are determined in quarterly composited air particulate filters. Stable strontium carrier is added to the sample and it is leached in nitric acid to bring deposits into solution. The mixture is then filtered. Half of the filtrate is taken for strontium analysis and is reduced in volume by evaporation. Strontium is precipitated as Sr(NO3 )2 using fuming (90%) nitric acid. A barium scavenge is performed to remove radium and other natural nuclides. An iron (ferric hydroxide) scavenge is performed, followed by addition of stable yttrium carr.ier and a 5 to 7 day period for yttrium ingrowth. Yttrium is then precipitated as hydroxide, is 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 Sr-90 activity. Sr-89 activity is determined by precipitating SrCO3 from the sample after yttrium separation. This precipitate is mounted on a nylon planchet and is covered with 80 mg/cm2 aluminum absorber for low level beta counting.

3. Results and Conclusions A summary of data is presented in Table 5-2.
a. Airborne Radioactive Particulates A total of five hundred twenty (520) weekly samples from ten (10) Mations were analyzed for gross beta. Results were comparable to previous years.

Figure 5-2 illustrates the average concentration of gross beta in air particulates. The weekly air particulate samples were composited to one hundred twenty (120) monthly samples which were analyzed by gamma spectrometry. Naturally occurring Be-7 was present in all but one sample. Naturally occurring K-40 was detected in twenty (20) of the one hundred twenty (120) monthly samples. Results are listed in the summary Table 5-2. A total of forty (40) quarterly samples were each analyzed for Sr-89 and Sr-90. No Sr-89 or Sr-90 was detected. Based on the analytical results, the operation of Beaver Valley Power Station did not contribute to any increase in air particulate radioactivity during 1995.

b. Radiolodine A total of five hundred twenty (520) weekly charcoal filter samples were analyzed for I 131. No detectable concentrations were present at any g locations. 5 Based on analytical results, the operation of Beaver Valley Power Station did not contribute to any increase in airborne radiciodine during 1995.

1. Characterization of Stream Sediments and Soils The stream sediments consist largely of sand and silt. Soil saraples may vary from sand and sitt to a heavy clay with variable amounts of organic material.
2. Sampling Program and Analytical Techniques I
a. Program River bottom sediments were collected semi-annually above the Montgomery Dam, in the vicinities of the Beaver Valley discharge and above the New Cumberland Dam. A Ponar or Eckman dredge is used to collect the sample. The sampling locations are also listed in Table 5-1 and are shown in Figure 5-3.

Bottom sediments are analyzed for gross alpha and beta activity, strontium, and the garnma-emitting radionuclides.

b. Analytical Procedures Gross beta - sediments and soils are analyzed for gross beta by mounting g a 1 gram portion of dried sediment in a 2" planchet. The sample is I counted in a low background, gas flow proportional counter. Self absorption corrections are made on the basis of sample weight.

Gross alpha activity of sediment or soll is analyzed in the same manner as gross beta except that the counter is set up to count only alpha. Gamma analysis of sediment or soil is performed in a 300 ml plastic bottle which is counted by a gamma spectrometer. I l 5-26 section S. ENVIRONMENTAL MONITORING PROGRAM

l Duquerna Light Company 1995 Annual Radiologics! Environmental Report Strontium 89 and 90 are determined by radiochemistry. The sample is first dried and weighed. Stable strontium and calcium carriers are added and the sample is leached in hydrochloric acid. The sample is filtered. Calcium and strontium are precipitated as phosphates, collected by vacuum filtration, then dissolved in nitric acid. Strontium is separated by precipitating Sr(NO3) using nitric acid. A barium scavenge is performed to remove radium and other natural nuclides. Final purification of strontium is accomplished by precipitating SrSO4 An iron scavenge is performed, followed by addition of stable yttrium carrier and a mlnlmum 5-day period for Y-90 ingrowth. Yttrium is then precipitated as hydroxide, is discolved 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 Sr-90 activity. Sr-89 activity is determined by precipitating SrCOs from the sample after yttrium separation. This precipitate is mounted on a nylon planchet and is covered with an 80 mg/cm' aluminum absorber for low level beta counting.

3. Results and Conclusions A summary of sediment analysis is presented in Table 5-2.
a. Sediment A total of six (6) samples were analyzed for gross alpha and gross beta. g Results were comparable to previous years. l A total of six (6) samples were analyzed for Sr-89 and Sr-90. No Sr-89 was detected. Sr-90 was detected at low level on one sample in the Beaver Valley Discharge Area and one sample upstream of the New Cumberland Dam.

A total of six (6) sample were analyzed by gamma spectrometry. Naturally occurring K-40, Ra-226 and Th-228 was found in every sample. Be-7 was found in one sample. Small amounts of Cs-137 from previous nuclear weapons test were found in all six river sediment samples including two upstream above Montgomery Dam, which are unaffected by plant effluents. Small amounts of Mn-54, Co-58, Co-60, Ag-110M, Sb-125 and Cs-137 were detected in the Beaver Valley Power Station discharge area and are attributable to station releases. The activity found in the station discharge area is consistent with station data of authorized radioactive discharges which were within limits permitted by the NRC license. The analyses demonstrate that the Beaver Valley Power Station did not contribute a significant increase of radioactivity in the Ohio River sediment. The positive results detected are attributable to authorized releases from the Beaver Valley Power Station and are characteristic of the effluent, These results confirm that the station assessments, prior to authorizing radioactive discharges, are adequate and that the I environmental monitoring program is sufficiently sensitive. 4 5-28 section 5.

Duquesne Light Company 1995 Annual Radiological Environmental Report D. Monitoring of Feederops and Foodcrops

1. Characterization of Vegetation and Foodcrops According to the 1994 statistical summary of the Pennsylvania Department of Agriculture, there were approximately 575 farms in Beaver County. The total value of farm crops and livestock was $17,332,000. The principal source of I revenue was in dairy products which were estimated at $6,693,000. Revenues from other farm products were estimated as follows:

Field Crops $1,786,000 Fruits $301,000 I Horticulture and Mushrooms S3,797,000 Meat and Animal Products $3,893,000 Vegetables and Potatoes $490,000 Poultry Products $112,000 The total land in Beaver County is 279,020 acres. Approximately 147,900 acres are forested land and 57,960 acres are pasture and crop land.

2. Sampling Program and Analytical Techniques
a. Program Representative samples of cattle feed are collected monthly from the -

nearest dairy (Searight). See Figure 5-4. Each sample is analyzed by gamma spectrometry. The monthly samples are composited into a quarterly sample which is analyzed for Sr-90. A land use census was performed July / August 1995 to locate the nearest residence and nearest garden of greater than 500 square feet producing I fresh leafy vegetables within a five (5) mile radius of the site. Table 5-5 for results. See Foodcrops (vegetables) were collected at garden locations during the summer of 1995. Leafy vegetables, i.e., cabbage, were obtained from Shippingport, Georgetown, and Industry, PA, and Weirton, WV. All samples were analyzed for gamma emitters (including 1-131 by gamma spectroscopy).

b. Procedures Gamma emitters, including 1-131, are determined by scanning a dried, homogenized sample with the gamma spectroscopy system. A high resolution germanium detector is utilized with this system.

Strontium 90 analysis for feedstuff is performed by a procedure similar to that described in 5-C.2 after drying, weighing and ashing the sample. Rad!oiodine (1-131) is determined by radiochemistry. Stable iodide carrier is first added to a chopped sample which is then leached with sodium hydroxide solution, evaporated to dryness and fused in a muffle furnace. j The melt is dissolved in water, filtered and treated with sodium j hypochlorite. The iodate is then reduced to lodine with hydroxylamine l hydrochloride and is extracted into chloroform. It is then back-extracted l as iodide into sodium bisulfite solution and is precipitated as palladium 3l iodide. The precipitate is weighed for chemical yield and is mounted on a El nylon planchet for low level beta counting.

3. Results and Conclusions A summary of data is presented in Table. 5-2.
a. Feed A total twelve (12) samples were analyzed for 1-131. No detectable concentrations were found.

A total of four (4) samples were analyzed for Sr-90. Small amounts of Sr-90 from previous nuclear weapons tests were present in all samples. A total of twelve (12) samples were analyzed by gamma spectroscopy. Naturally occurring K-40 was present in all samples and Be-7 was detected in five (5) samples.

b. Food A total of four (4) samples were analyzed for I-131. No detectable concentrations were present.

A total of four (4) samples were analyzed by gamma spectrometry. Naturally occurring K-40 was present in all samples.

c. The data from food and feed analyses were consistent with previous data. .

These data confirm that the Beaver Valley Power Station did not contribute to radioactivity in foods and feeds in the vicinity of the site. I; l l 5-32 SecUon S. ENVIRONMENTAL MONITORING PROGRAM Il l

1. Description - Milch Animal Locations 1

During the seasons that animals producing milk (milch animals) for human consumption are on pasture, samples of fresh milk are obtained from these g animals at locations and frequencies noted in Table 5-1. This milk is analyzed g for its radiciodine content calculated as lodine-131. The analyses are performed I within eight (8) days of sampling, i Detailed field surveys are performed during the grazing season to locate and enumerate milch animals within a five (5) mile radius of the site. Goat herd locations out to fifteen (15) miles are Identified. Survey data for the most recent I survey conducted in is shown in Figure 5-5.

2. Sampling Program and Analytical Techniques I a. Program Milk was collected from these (3) reference dairy farms (Searight's, Brunton's and Nicol's) within a 10-mile radius of the site and from one (1) control location (Windsheimer's) outside of the 10-mile radius. Additional ,

dairies, which represent the highest potential milk pathway for radiciodine l based on milch animal surveys and meteorological data were selected and sampled. These dairies are subject to change based upon availability of milk or when more recent data (milch animal census) indicate other i locations are more appropriate. The location of each is shown in i Figure 5-6 and described below. l l Direction and Distance from Collection

FIGURE 5 ENVIRONMENTAL MONITORING LOCATIONS MILK w, Section 5. ENVIRO" MENTAL MONITORING PROGRAM 5-35

Duquesne Light Company , 1995 Annual Radiological Environmental Report l l The sample from Searight Dairy was collected and analyzed weekly for radiciodine using a procedure with a high sensitivity. Samples from each of the other selected dairies were collected monthly when cows are indoors, and bi-weekly when cows are grazing. This monthly or bi-weekly sample is analyzed for Sr-89, Sr-90, gamma emitters including Cs-137 (by high resolution germanium gamma spectroscopy) and 1-131 (high sensitivity analysis),

b. Procedure Radiciodine (1-131) analysis in milk was normally performed using chemically prepared samples and analyzed with a low-level beta counting system.

Gamma emitters are determined by gamma spectroscopy of a one liter Marinelli container of milk. Strontium milk samples are prepared by adding stable strontium carrier and evaporating to dryness, then ashing in a muffle furnace, followed by precipitating phosphates. Strontium is purified in all samples in a chromatographic column. Stable yttrium carrier is added and the sample is allowed to stand for a minimum of 5 days- for the ingrowth of Y-90. Yttrium is then precipitated as hydroxide, is 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 Sr-90 activity. Strontium-89 activity is determined by precipitating SrCO2 from the sample after yttrium separation. This precipitate is mounted on a nylon planchet and is covered with an 80 mg/cm' aluminum absorber for low level beta counting. Chemical yields of strontium and yttrium are determined gravimetrically.

3. Results and Conclusions A summary of data is presented in Table 5-2.

A total of one hundred sixty-six (166) samples were analyzed for I-131 during 1995. All 1-131 activities in milk were below the minimum detectable level. A total of one hundred thirty-three (133) samples were analyzed for Sr-89 and S r-90. No Sr-89 was detected. Sr-90 levels attributable to previous nuclear weapons tests were detected in all samples and were within the no mally expected range. A total of one hundred thirty-three (133) samples were analyzed by gamma spectroscopy. Naturally occurring K-40 was present in all samples. It was noted that the dairies with the highest annual mean activities were goat dairies, which are known to concentrate activities over a factor of two compared to a cow dairy. All results were consistent with (or lower than) those obtained in the preoperational program. These data confirm that the Beaver Valley Power Station did not contribute to radioactivity in milk in the vicinity of the site. 5-36 Section 5. ENVIRONMENTAL MONITORING PROGRAM

1. Description of Regional Background Radiation and Sources The terrain in the vicinity of the Beaver Valley Power Station generally consists of rough hills with altitude variations of 300-400 feet. Most of the land is wooded.

The principal geologic features of the region are nearly flat-laying sedimentary I beds of the Pennsylvania Age. 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 I 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. Based on surveys reported in previous annual reports, exposure rates ranged from 6-12 />R/hr. Results for 1995 indicated that background radiation continued I in this range.

2. Locations and Analytical Procedures Ambient external radiation levels around the site were measured using thermoluminescent dosimeters (TLDs).

In 1995 there were a total of forty-four (44) off-site environmental TLD locations. The locations of the TLDs are shown in Figure 5-7 through Figure 5-10. Thirteen (13) locations also have QC Laboratory TLDs. Both laboratories use calciem sulfate dysprosium, (CaSO4:Dy) in Teflon matrix. The calcium sulfate dysprosium (CaSO.:Dy) TLDs were. angealed at the I Contractor Central Laboratory shortly before placing the TLDs in their field locations. The radiation dose accumulated in-transit between the Central Laboratory, the field location, and the Central Laboratory was corrected by I transit controls maintained in lead shields at both the Central Laboratory and the field office. All dosimeters were exposed in the field in a special environmental holder. The dosimetry system was calibrated by reading calcium sulfate I dosimeters which have been exposed in an accurately known gamma radiation field. I l r l ] Section 5.

3. Results and Conclusions l

Data obtained with the contractor TLD (CaSO :Dy in Teflon) durirg 1995 are summarized in Table 5-2, and the quality control TLD results are . listed in Table 3-1. The annual exposure rate of all offsite TLDs averaged 0.179 mR/ day in 1995. As in previous years, there was some variation among locations and seasons as would be expected. Four TLDs (two quarterly, two annual) were lost in the field during the year. Two quarterly TLDs were also lost in processing. In 1995, ionizing radiation dose determinations from TLDs averaged approxirnately I 65.3 mR for the year. This is comparable to previous years. There was no evidence of anomalies that could be attributed to the operation of the Beaver Valley Power Station. The TLDs confirm that changes from natural radiation levels, if any, are negligible. l l l l l l 1 1 l 1 l 5-33 Section 5. ENVIRONMENTAL MONITORING PROGRAM j

Duquesne Light Company 1995 Annual Radiological Environmental Report G. Monitoring of Fish

1. Description During 1995, fish collected for the radiological monitoring program included carp and catfish.
2. Sampling Program and Analytical Techniques
a. Program Fish samples are collected semi-annually in the New Cumberland pool of the Ohio River at the Beaver Valley effluent discharge point and upstream of the Montgomery Dam. The edible portion of each different species caught is analyzed by gamma spectroscopy. Fish sampling locations are shown in Figure 5-11.

I

 .             b. Procedure A sample is prepared in a standard tared 300 mi plastic bottle and scanned I                for gamma emitting nuclides with gamma spectrometry system which utilizes a high resolution germar,Lm detector.
3. Results and Conclusions A summary of the results of the fish monitoring data is provided in Table 5-2.

A total of eight (8) samples were analyzed by gamma spectroscopy. Naturally occurring K-40 was found in all samples. No other gamma emitting I radionuclides were detected. The analyses demonstrate that the Beaver Valley Power Station did not contribute a significant increase of radioactivity in the Ohio River fish population. I I I l I i I ~ Section 5.

Duquesne Light Company 1995 Annual Radiological Environmental Report H. Monitoring of Surface, Drinking, Well Waters and Precipitation

1. Description of Water Sources The Ohio River is the main body of water in the area. It is used by the Beaver Valley Power Station for plant make-up for the cooling tower and for receiving plant liquid effluents.

Ohio River water is a source of water for some towns both upstream and downstream of the Beaver Valley Power Station site. It is used by several municipalities and industries downstream of the 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 and on the opposite side of the river. The next downstream user is East Liverpool, Ohio which is approximately 6 miles downstream. The heavy industries in Midland, as well as others downstream use river water for cooling purposes. Groundwater occurs in large volumes in the gravel terraces which li e along the river, and diminishes considerably in the bedrock underlying the site. Normal well yields in the bedrock are less than 10 gallons per minute (gpm) with occasional v ells 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 record mean annual precipitation for the area is 36.43 inches based on 1965 to .1994 data collected at the Pittsburgh International Airport. ( section 5. ENVIRONMENTAL MONITORING PROGRAM 5-45

2. Sampling and Analytical Techniques
a. Surface (Raw River) Water The sampling program of river water includes five (5) sampling points along the Ohio River. Raw water samples are normally collected at the East Liverpool (Ohio) Water Treatment Plant [ River Mile 41.2] daily and composited into a monthly sample. Weekly grab samples are taken from the Ohio River at the following locations: upstream of Montgomery Dam

[ River Mile 31.8]; and near the discharge from the Beaver Valley Power Station [ River Mile 35.0]. Two automatic river water samplers are at the following locations: Upstream of Montgomery Dam [ River Mile 29.6]; and at J&L Steel's river water intake [ River Mile 36.2]. The automatic sampler takes a 20-40 mi sample every 15 minutes and samples are collected on a weekly basis. The weekly grab samples and automatic water samples are composited into monthly samples from each location. In addition, a quarterly composite sample is prepared for each sample point. The weekly composites from the automatic river water sampler upstream at Montgomery Dam are analyzed for 1-131. The monthly composites are analyzed for gross alpha, gross beta, and gamma emitters. The quarterly composites are analyzed for H-3, Sr-89, Sr-90, and Co-60 (high sensitivity). Locations of each sample point are shown in Figure 5-12.

b. Drinking Water (Public Supplies)

Drinking (treated) water is collected at both Midland (PA) and East Liverpool (OH) Water Treating Plants. An automatic sampler at each location collects 20-40 mi every 20 minutes. These intermittent samples  ; are then composited into a weekly sample. The weekly sample from each location is analyzed by gamma spectroscopy. The weekly samples are also analyzed for 1-131. l Monthly composites cf the weekly samples are analyzed for gross alpha, gross beta, and by gamma spectrometry. Quarterly composites are analyzed for H-3, Sr-89, Sr-90 and Co-60 (high sensitivity). Locations of each sample point are shown in Figure 5-12. 1 i I 5-46 Section 5. ENVIRONMENTAL MONITORING PROGRAM

Duquesne Light Company 1995 Annual Radiological Environmental Report [ c.

e. Procedures Gross alpha and cross beta activities are determined first by evaporating one liter of the sample on a hotplate. The residue is mounted and dried on a 2-inch stainless steel planchet. The sample is counted in a low background, gas flow proportional counter. Self-absorption corrections are made on the basis of sample weight.

Gamma analysis is performed on water sample by loading one liter of sample into a one liter Marinelli container and counting a high resolution germanium gamma spectrometry system. Strontium-89 and 90 are determined on water samples by a procedure similar to that described in 5-C.2 except that the leaching step is eliminated. Cobalt-60 is determined with a sensitivity of 1 pCl/ liter by evaporating 2 liters of sample on a hotplate and transferring the residue to a 2-inch planchet. The planchet is counted on a high resolution germanium gamma spectrometry system. Tritium is determined in water samples by liquid scintillation counting. Radiolodine (I-131) analysis in water was normally performed using chemically prepared samples and analyzed with a low-level beta counting system.

3. Results and Conclusions A summary of results of all analyses of water samples (surface, drinking, ground and precipitation) are provided by sample type and analysis in Table 5-2. These are discussed below.
a. Surface Water A total of forty-eight (48) samples were analyzed for gross alpha and gross beta. Alpha activity was detected at the lower limit of detection ~in one of the samples. Surface water may contain sediment which contains naturally occuring alpha radioactivity. Positive beta results above preoperational levels were detected in the BVPS discharge area and are attributable to station releases. The beta activity found in the station discharge area is consistent with station data of authorized radioactive discharges and were within limits permitted by the NRC license.

Section 5. ENVIRONMENTAL MONITORING PROGRAM 5-49

i Duqunsne Light Company 1995 Annual Radiological Environmental Report A total of sixteen (16) samples were analyzed for H-3, Sr-89 and Sr-90 as well as a high sensitivity analysis for Co-58 and Co-60. Positive tritium results were detected in the BVPS discharge area and are attributable to station releases. The highest tritium results have been noted, however, to correspond to shore samples taken when mixing zone sampling by boat was not possible. All other samples taken upstream and downstream were within preoperational levels. The activity found in the station discharge area is consistent with station data of authorized radioactive discharges and were within limits permitted by the NRC license. A total of forty-eight (48) samples were analyzed by gamma spectrometry. No gamma emitting radionuclides were detected. A total of fifty-two (52) samples were analyzed for I-131 using a highly sensitive technique. Trace levels of I-131 were measured in twenty-two (22) of the weekly samples. The results were slightly above the minimum detectable activity. The positive results were detected at a control location above the BVPS discharge and could not be attributed to plant releases. The results may be attributed to medical procedures and the expected variability in the analyses results of very low levels of activity.

b. Drinking Water A total of twenty-four (24) samples were analyzed for gross alpha and gross beta. All results were within a normal range.

A total of eight (8) samples were analyzed for H-3, Sr-89 and Sr-90 as well as a high sensitivity analysis for Co-60. No H-3, Sr-89, Sr-90, or Co-60 were detected.  ; A total of one hundred four (104) samples were analyzed by gamma ) spectrometry. No gamma emitting radionuclides were detected. A total of one hundred four (104) samples were analyzed for I-131 using a highly sensitive technique. Trace levels of I-131 were measured in i seventy-one (71) of the weekly samples. The results were slightly above l tho minimum detectable activity. The positive results were detected at Midland and East Liverpool and could not be attributed to plant releases. As noted under Surface Water above,1-131 has been observed upstream of g ' the site. The results may be attributed to medical procedures and the l expected variability in the analyses results of very low levels of activity,

c. Groundwater A total of fourteen (14) samples were each analyzed for gross alpha, gross beta, H-3 and by gamma spectrometry. Only two samples were obtained g at Meyer Farm because the farm was only occupied two quarters. Alpha g and H-3 activity were not detected. The gross beta results are comparable to preoperational ranges. No gamma emitting radionuclides were detected.

e. Summary The data from water analyses demonstrates that the Beaver Valley Power Station did not contribute a significant increase of radioactivity in local river, drinking, well waters or precipitation. The few positive results which

[ could be attributable to authorized releases from the Beaver Valley Power l Station are characteristic of the effluent. These results confirm that the station assessments, prior to authorizing radioactive discharges, are adequate and that the environmental monitoring program is sufficiently sensitive. Further, the actual detected concentration (averaged over the total batch discharge period during the year) attributable to Beaver Valley Power Station, was only 0.110% of the limits set forth in Appendix C of the ODCM for water discharged to the Oh!o River. The Ohio River further reduced [ this concentration by a factor of ~ 600 prior to its potential use by members of the public. [ { { [ [ [ { Section S. ENVIRONMENTAL MONITORING PROGRAM 5-51

1. Estimates of Radiat!on Dose to Man
1. Pathways to Man - Calculational Models l l

The radiation doses to man as a result of Beaver Valley operations were  ; calculated for both gaseous and liquid effluent pathways using codes for the l ARERAS/ MIDAS computer system equivalent to NRC computer codes XOQDOQ2, GASPAR, and LADTAP. Dose factors listed in the ODCM were used to calculate  ; doses to maximum individuals from radioactive noble gases in discharge plumes. Beaver Valley effluent data, based on sample analysis in accordance with the schedule set forth in Appendix A of the BVPS license, were used as the radionuclide activity input. Each radionuclide contained in the Annual Radioactive Effluent Release Report (noble gases, particulates, radiolodines and tritium) were included as source terms when they were detected above the LLD values. All LLD values reported by Beaver Valley Power Station are equal to or lower than those required by the Technical Specifications lODCM. All gaseous effluent releases, including Auxiliary Building Ventilation, were included in dose assessments. The release activities are based on laboratory analysis. Meteorological data collected by the Beaver Valley Power Station Meteorology System was used as input to code equivalent to XOQDOQ2 which in turn provided input for the GASPAR equivalent. Except when more recent or specific data was available, all inputs were the same as used in the Beaver Valley Power Station Environmental Statements or in Regulatory Guide 1.109. The airborne pathways evaluated were beta and gamma doses from noble gas plumes inhalation, the " cow-milk-child", and other ingestion pathways. All potentially radioactive liquid effluents, including steam generator blowdown, are released by batch mode after analysis by gamma spectrometry using Intrinsic Germanium detectors. Each batch is diluted by cooling tower blowdown water prior to discharge into the Ohio River at the Beaver Valley Power Station outfall (River Mile 35.0). The actual data from these analyses are tabulated and used as the radionuclide activity input term in code equivalent to LADTAP. A hypothetical real individual for liquid pathways is located at Midland. Except when more recent or specific data for the period is available, all other input are obtained from the Beaver Valley Power Station Environmental Statement or Regulatory Guide 1.109. Pathways, which were evaluated, are drinking water, fish consumption, shoreline recreation, swimming, and boating. i l l I: 5-52 section 5. ENVIRONMENTAL MONITORING PROGRAM

2. Results of Calculated Radiation Dose to Man - Liquid Releases I a. Individual Dose The doses which are calculated by the model described above are to a i hypothetical reel individual located at Midland since this is the nearest location where significant exposure of a member of the public could potentially occur; therefore, this location is use to calculate the maximum I exposure. A breakdown of doses by pathway and organ is provided in Table 5-6 for the maximum individual. Included in this table is a breakdown of a typical dose to individuals from natural radli; tion exposure.

i The results of calculated rad!ation dose to the hypothetical real individual are compared to BVPS annual limits in Table 5-7.

b. Upon implementation of the Unit 2 Technical Specifications and inception of the liquid discharge procedures at Unit 2 on July 24,1987, the discharge limits were clarified to be reactor specific; i.e., Unit 1 and Unit 2 have reactor specific dose limits that are equal to the limits in 10 CFR Part 50, Appendix 1. Therefore, the annual site limits listed in Table 5-8 are specific to this report only, and were derived by multiplying the individual Technical Specification reactor limits by a factor of two (2).

3. Results of Calculated Radiation Dose to Man - Atmospheric Releases The results of calculated radiation dose to the maximum exposed individuals for BVPS airborne radioactive effluents during 1995 are provided in Table 5-8. The doses include the contribution of all pathways. A 50-mile population dose is riso a calculated and provided in Table 5-8. H-3 is the primary radionuclide contributions to these doses.

The results are compared to the BVPS annual limits in Table 5-8. As in the liquid discharge limits, the gaseous effluent limits are reactor specific; i.e., Unit 1 and Unit 2 have reactor specific dose limits that are equal to the limits in 10 CFR Part 50, Appendix 1. Therefore, the annual limits listed in Table 5-8 are specific to this report only, and were derived by multiplying the individual Technical g Specification reactor limits by a factor of two (2). The results show compliance 5 with the BVPS annual limits. I I 5-56 Section S. ENVIRONMENTAL MONITORING PROGRAM

Duquesne Light Company 1995 Annual Radiological Environmental Report

4. Conclusions Based upon the estimated dose to individuals from the natural background radiation exposure in Table 5-6, the incremental increase in total body dose to the 50-mile population (4 million people), from the operation of Beaver Valley Power Station - Unit 1 and 2, is less than 0.0003% of the annual background.

The calculated doses to the public from the operation of Beaver Valley Power Station - Unit 1 and 2, are below BVPS 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. Section 5. ENVIRONMENTAL MONITORING PROGRAM 5-57

The result, 52 pCi/1. was in gcod agreement with the EPA. The three original results, each counted on a different detector, showed good precision. The measurement of Co-60 has not been a problem. Future EPA cross-checks will be weighed and results followed to check for a possible trend "out of control". (g) The average value of three analyses on the " Report of Analysis" was 133 pCi/ liter which is in good agreement with the EPA. Apparently. Incorrect results were entered into the EPA computer. Future data will be printed from the computer screen to check entries. (h) The EPA has indicated that the Radiation Quality Assurance Program has been experiencing problems v"th the ruthenium-lO6 analysis. See attached letter from EPA. { (0 The first aliquot, prepared according to EPA dilution instructions was counted on four detectors in the 1 liter Marinelli geometry with Cs-134 results (based on the 796 kev peak) in pCl/l of 32.0, 25.1, 31.7, and 30.8. The 31.7 result was not reported. Had that been ( reported instead of 25.1, the average would have been 31.5 and the normalized deviauon would have been -2.94 instead of -3.70. A second aliquot was prepared and a single measurement was made with the result of 31.1 pCi/1. An undiluted aliquot was measured in [ a 150 ml geometry with the result of 33.5 pCi/1. That result is comparable with the Marinelli results. Thus none of : sample preparation (dilution, volume determinauon, maintaining correct pH, etc.), sample geometry, or detector efficiency seem to be the cause of the low results. { Q) There is no apparent reason for the low result, however the average value, 85 pCl/l is in good agreement to the grand average (86.46). No corrective action planned. [ (k) EPA results for gross beta in water were corrected for 20% crosstalk into the beta channel from the Th-230 alpha spike. Recent measurements show that the crosstalk can be much r higher (37% for Tennelec counter #3 and 54% for gamma products counter #1). The L normalized deviation from the grand average was only 0.38, Future results will be corrected with specific crosstalk values determined by counting Th-230 standards. Possible aliquoting error. The instrument calibration, spike, and blank results all appear

~

(O normal. No procedural changes are planned. Previous results were well within one normalized deviation. Future measurements will be reviewed to determine if a trend in results above the two sigma warning limit is occurring. (m) The milk sample was counted four times. The reported Cs-137 values were based on one aliquot of I liter volume and an aliquot of 0.865 liter counted two times. It is suspected that the 0.865 liter volume was incorrectly determined. If I liter (the usual volume for counting milk samples) is used in the calculation, then the average of three results equals 63.6 pC1/1 which gives a normalized deviation to the Known of 1.59. The fourth count (a 1 liter aliquot) had a Cs-137 equal to 64.2 pC1/1 which is in good agreement with the average of the other three. Teledyne will set up a log for recording aliquots used for EPA samples and record how the aliquot volume was determined.  ; L

(b) Expected laboratory precision (1 sigma. I deterir- on) (c) Normalized deviation from the known. (d) An investigation is being conducted; results will be available shortly. (d) The normalized deviation marginally exceeded the warning Icvel and an apparent trend in the results appeared. The cause was a probable high bias in the beta counting effletency. Check source control charts did not indicate any changes in the counting equipment, so the I-131 calibration was suspected. New 1-131 calibrations were performed July 3 thtough G. 1995 after receiving a new standard from the EPA. De Interromparison sample data sheets were recalculated with the new efliciencies and the average result was in excellent agreement with the EPA (96 pCl/l versus the EPA value of 100 pCi/I). The discrepancy in the I-131 efficiency between the current calibration and the previous one (aside from the uncertainty in the standard) appears to be an abnormally low yield in the preparation of the standard for the older calibration which crea;ed a high bias in the owter efficiencies. he bias was less than ten percent, therefore further corrective action or revision of previously reported data is deemed not necessary. (e) he mineral salt content of the water used by the EPA to prepare the samples has been shown to vary substantially throughout the year. Absorption curves to amount for mount weight may vary from the true absorption characteristics of a specific sample. Previous results do not indicate a trend toward "out of control' for gross alpha / beta analysts and the normalized deviation from the grand average is only -0.36. De normalized deviation from the known for'IIIE-ES does not exceed three standard deviation and internal spikes have been in control. No corrective action is planned at this time. M M M M

Accendix A Interlaboratory Comoarison Program Results Tcledyne's Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides know to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and to alert it to any possible problems. Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency, Several months later, the agency reports the known values to the participant laboratories and specifies controllimits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

       'Ihe results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

This program is conducted by the U.S. Environmental Protection Agency Intercomparison and

     . Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Pasirr eters (TLDs), since 1976 via various International Intercomparisons of Em ironmental Dor,uneter , under the sponsorships listed in Table A-2. 'Also Teledyne testing results are listed. Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months. Data for previous years available upcn request. Table A-4 lists results of the analyses on in-house " blank" samples for the past twelve months. Data for previous years available upon request. Tab!c A-5 list results of the in-house " duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon requ-st. Attschment A lists acceptance criteria for " spiked" samples. Out-of-limit results are explained directly below the result. A1
