S USQ UEH A N NA S ES-E R-OL 2 3. 1 2. 2 Tornadoes The incidence of tornadoes in the site area is very low. Between the years 1950 and 1973 only 38 tornadoes were reported within 50 miles of the site. Tornado activity is at a maximum during the summer months with most tornadoes occurring in the late afternoon or evening. Figure 2. 3-1, Tornado Occurrence <<nd Intensity in the Susquehanna SZS Reqion, is a histogram for the years 1953-1962 showing tornado frequency by month, hour and intensity within a 3 by 3~ square which is centered on the site. The intensity cateqories are based on the Fujita tornado intensity classification (Ref. 2.3-5). Prom Figure 2.3- 1 it can be seen that maximum tornado occurrence is in the summer. Diurnally, tornado frequency reaches a maximum during late afternoon, shortly after the period of greatest instability 2 3.1. 2 3 Th>>ndec storms Thunderstorms in the area are usually of brief duration and concentrated in the warm months. They are responsible foc most of the summertime rainfall which normally avecaqes around 3.7 inches per month at Avoca. Based on a 19 year average at Avoca the mean number of "days with thunder heard" is 30 (Ref 2.3-3) .

A monthly breakdown of the mean number of thunderstorm days that is representative of the site is shown in Table 2.3-2, Th understocm Days for Avoca.

2. 3. 1 2. 4 L~iht ning There is neither documentation nor direct measurement of the occurrence of lightning other than the observation of associated thunder. Local climatological data tabulated by the National Weather Service (Ref. 2. 3-3) does not provide information reqardinq the incidence, severity. or frequency of lightning occurrences A .thunderstocm can usually be heard unless the liqhtning causing the thunder is more than 15 miles away; therefore, thunder incidence can presumably be used to confirm the presence of some lightning The number of lightning strikes per square mile per year has been established by, Uman (Ref. 2.3-6) . The combined results of several studies summarized ny Uman indicate that the number of flashes to the qround pec square mile per year is between 0 05 and 0.80 times the number of thunderstorm days pec year. The mean number of days with thunderstorms probably over estimates the actual occurrence of cloud-to-ground lightning since some thunderstocms probably contain only cloud-to-cloud lightning.

2~3 3

SUSQUEHANNA S ES-ER-OL Therefore. if the annual thunderstorm frequency at Avoca is used (30 days), the number of: ground lightning strikes is between two and 24.

2 3 1 2 5 Hail Hail in the site region sometimes falls from severe thunderstorms. Because hail f alls in narrow swa ths, only a small fraction of occurrences is recorded at regular reporting stations The average annual number of days with hail at a point in the area is 23. The occurrence of large hail (greater than

0. 75 inches diameter) averaqes one or two occurrences annually Accordinq to Pautz (Ref. 2.3-7) the number of hailstorms with hail 0.75 inch or greater in a one-degree longitude-latitude square area in the vicinity of the site for the period 1955-1967 was about five For Avoca from 1973-75 there was one hailstorm in June and one in July of 1973 and 1974. Xn 1975 there was also one hailstorm in August and one in October There were no occurrences of hail recorded in 1976 at Avoca (Ref. 2.3-3) 2 3.1 2 6 Extreme Minds Strong winds occur in Pennsylvania as a result of occasional hurricanes, thunderstorms, tornadoes and tropical storms. The followinq is the fastest mile of wind and its associated direction, by month, at Avoca (1955-1976) (Ref. 2.3-3).

Accordinq to Pautz, there were eight windstorms 50 knots and qreater for the one degree latitude-longitude square that includes the Susquehanna SES for the period 1955-1967 (Ref. 2 3-7) .

SUSQU EHANNA S ES-ER-OL site) and at Danville (about 31 miles (49.9 km) downstream. The Corps of Engineers has compiled flood stage and discharge

. information for the Susquehanna River at Wilkes-Barre (Ref. 2.4-7). These data are based on records of flood stages dating from 1991 Data for the four most severe floods of record are presented in Table 2.4-5, Historic Floods in the Vicinity of the Susquehanna SES Table 2.4-5 also includes the stages and discharges f or floods at the site and at Danville. The flood frequency characteristics of the Susquehanna as measured at Danville are illustrated in Figure 2.4-6, Flood Discharge Frequency.

The passaqe of Tropical Storm Agnes through. Pennsylvania on June 22 and 23, 1972 resulted in record flood levels in the Susquehanna River Basin Flood crests exceeded the previous record flood level .of 1936 at Wilkes-Barre by 7 5 feet (2.3 m).

At Danville, a local maximum qaqe level resulting from a 1904 ice jam was exceeded by 1.6 feet (0.5 m) . Peak discharqe at Wilkes-Barre was an estimated 345,000 cfs (9,770 m~/sec) or a unit discharge of 34.5 cubic feet per second per sguare mile (cfsm)

2 4. 2 5 Low Plows Long term records from the USGS gaging stations at Danville and Wilkes-Barre provide the data base for the low flew f requency analyses presented in this Subsection. Long duration low flow f requency analysis has been performed by the Pennsylvania Department of Environmental Resources (DER). The resulting curves for low f3.ow durations of two to 60 months and recurrence intervals up to 100 years for Danville and Wilkes-Barre are provided in Figures 2.4-7, Low Flow Duration at Danville and 2.4-8 ~ Low Flow Duration at Wilkes-Barre, respectively.

Tables 2.4-6 and 2.4-7, Maqnitude and Frequency of Annual Low Flow of the Susquehanna River at Danville and Wilkes-Barre, Pa.

respectively, discuss the discharge for different recurrence intervals. Tables 2.4-8 and 2.4-9, Duration Table of Daily Flow of the Susquehanna River at Danville and Wilkes-Barre, Pa.

respectively indicate the river discharge (Ref. 2.4-14) .

The most extended drought period occurred in the 1960's. The lowest consecutive day flows for periods of 183 days and less have also occurred in this period The mean monthly flows at Danville and Wilkes-Barre are provided in Table 2.4-10a, Mean Monthly Drought Year Flow Sequences. Mean Daily Flows During 1964 Drought, Table 2.4-10b for these two stations are provided for the four lowest flow months of this year 2 4-5

S USQ U EH A NNA S ES-E R-OL A policy decision 'of the Susquehanna River Basin Commission reqardinq consumptive withdrawals during low flow periods provides that natural flows during droughts will not he diminished by future water users. On September 30 1976, this policy decision was implemented as an Amendment to 18 CFR Part 80'3 (Susquehanna River Basin Commission, Subpart D Standards for Review, Section 803.61, Consumptive Uses of Mater) (Ref. 2.4-15). Compensation shall be reguired for consumptive uses of water during periods of low flow. The provisions of this regulation apply to consumptive uses initiated since January 23, 1971 2 4 2 6 Sedimentation Annual sediment yields in the reqion surrounding the site are spacially uniform. Neasurements at Towanda, Pa. about 105 miles (169 km) above the station, indicate on annua'ediment yield of 150 tons/sq mi (52.5 metric tons/km~) from a drainaqe area of 7797 sq mi (20,194 km~) . Annual yields at Danville, 11,220 sq mi (29,060 km~) drainage area are estimated to be 140 tons/sq mi (49.0 metric tons/km~) (Ref 2 4-8) . Daily sediment discharges at individual stations are highly variable The daily sediment discharqe at Danville ranqes from a high of 556, 000 tons/day (504,400 metric tons/day) to a low of 18 tons/day (16.3 metric tons/day) .

Mater quality samplinq at the site included measurement of total suspended solids A range of values from 1. 6 mg/1 to 912.6 mq/1 with an averaqe value of 57. 0 mg/1 was found. These results are further reported in Subsection 2.4 3.

Grain size analysis was performed on water samples taken in 1974 usinq an automatic image analyzer. The grain size determination was performed on treated and untreated river water samples. The results for the untreated samples are reported in Table 2 4-11, Sediment Grain Size Distribution.

2 4 2 7 Mater Impoundments The Susquehanna River supplies all the water required for normal station operation. A seven-acre (2.8 ha.) spray'ond is located onsite to supply water to emergency heat dissipation systems.

The warmed water from the reactors is cooled via the pond's spray system and then recirculated throuqh the emergency cooling systems.

This spray pond has a relatively impervious liner. It is free-form in shape to conform to the natural topography of the area.

Embankments and ditches are provided to direct surface water

Each chart is removed separately and placed in individual boxes labeled with date, instrument'nd level. The charts are inspected for breaks in record, time errors, power failures and other indications of system malfunction and then stored. The information gained from this inspection is used to update and verify the digital data, and to locate anomalies with any parameter. The analog recording system provides a back-up in case of digital system failure, so that a high data recovery rate can be maintained. Table 6.1-2, Data Recovery Bates, gives the recovery rates for each year.

Digital minute data are recorded at the site on magne ic tape for analysis. At the begi.nning of each scan of data a unique identification code, the date,'hour and minute is recorded.

After 14 days of recording, the tape is removed, labeled with the data period and forwarded to the Applicant, The computer

facility processes these tapes converting the recorded millivoltaqes into enqineerinq units.

An hourly averaqe for each parameter is computed Data validity, range of hourly averages and the number of valid observations contributinq to the averages are tabulated to assist in the determination of data reliability. Comparisons between the analog and diqital data are performed when the bi-weekly review of the digital data reveals qu'estionable or invalid data.

Temperature and dew point hourly averages are computed using the f ollowinq scalar equation:

B. = 1 n .

Z r.j B.. ji i=1 where:

the average hourly value for the jth variable (in physical units);

the total number of minute observations during the hour (normally 60), but that hour, data are if considered n is less than 15 f or to be missing; B.. the i" minute observation on the 3+" variable (millivolts):

the conversion factor to change the j<hvariable from millivolts into physical units.

After wind speed (WS) and wind direction (WD) are converted from millivolts they are related in the followinq manner:

If WS is invalid (999) then vice versa.

WD is marked invalid (999) and If is )setthreshold WD WS (non-calm) to 360~ (North) and WD = 0 (implying calm) then If is WD WS ( threshold (calm) set to 0o (calm) and WD ) 0 (implying non-calm) then Hourly averages are computed as scalars for wind speed. Wind direction averages are, determined as follows:

If the associated averaqe wind speed is greater than 1.34112 meters/sec, (3 mph), average WD is determined by vector analysis (where WS and WD for each minute determines a vector) .

INTRODUCTION The PP&L energy model forecasts KWH consumption for each of the major groups in the PP&L Service Area; i.e.,

o RESIDENTIAL o COMMERCIAL o INDUSTRIAL o RESALE, STREET LIGHTING AND RAILROAD An econometric model is developed by considering the determinants for each of the sectors. While the model, by necessity, is a simplification, it captures the crucial linkages between sector activity and KWH sales, providing the user with a structural framework for forecasting. Through the model a user can produce a forecast of sales for each of the sectors consistent with an economic outlook. More importantly the impact of alternative economic scenarios can be tested.

In arriving at a forecast, the model utilizes information and forecasts of the U.S. economy, the national energy market, the Central Eastern Pennsylvania (C.E.P.)

economy, local weather conditions and company policy. This information is obtained from a combination of existing forecasting services and reviews with PP&L Energy Consultants. The PP&L model builds from that point, measuring the impact of the national economic outlook on the C.E.P. region. This outlook is then combined with assumptions about weather conditions and company policy to produce a forecast of energy sales to each of the sectors.

MODEL STRUCTURE In developing a model of electric energy consumption for a particular region it is important to, Qrst, define the demand conditions present in that service area, and second, measure their impact on sales to each of the sectors. The PP&L energy model is developed within this two-stage process.

In the first stage of the model, demand conditions are defined, i.e.,

climatic conditions, the economic environment, energy prices, and company policy.

Weather, energy'costs and company policy are all exogenous inputs to the model.

The economic conditions are developed endogenously through an'conometric frame-work.

The second stage measures the impact of these demand conditions on each sector through a set of econometric equations, relating sales to those factors that are known to affect growth. The general flow of the model is given. in Figure I.

The service area economic model is linked to the DRI Macro Economic Model, bridging the gap between the national economy and local sales by highlighting regional characteristics (i.e., industrial mix, growth trends, demographic mix, etc.) and by including explicitly the impact of the national economy on the region. This linkage is primarily through the industrial sector. For example, the steel industry in the C.E.P. region serves a national market, therefore, their sales depend on demand conditions in the nation. In developing a model to forecast the growth of the steel industry in the region it is necessary to include national economy. As another ex-ample, the housing industry in the area is heavily dependent on local wealth and demographic mix, but a depressed steel industry would lower local wealth thereby slowing housing growth. The function of the service area model is to liter these national conditions so as to measure their impact on the local economy.

Thus, the electric use forecast is developed in the following way. A fore-cast of the national economy, developed through the DRI Macro Model, is accepted or altered to reflect PP&L.'s thinking. That forecast is fQtered through the service area economic model to determine local economic conditions. Again the user has the option of accepting the results or altering them where he deems necessary. The economics are combined with assumptions about energy prices, expected weather conditions and company policy to define the local demand conditions. Finally, this information determines the expected level of megawatthour sales. At each stage the forecaster has the ability to adjust the output of the model before going on. It allows the user the required Qexibility to make the model a useful tool.

The next three sections detail the methodology used in developing the economic and energy models.

SERVICE AREA ECONOMIC MODEL The Central Eastern Pennsylvania (C.E.P.) economic model is constructed to highlight the regional economy within the PP&L service area. It provides infor-mation about four major economic areas:

A. INDUSTRIAL SECTOR B. COMMERCIAL SECTOR C. WAGES & PERSONAL INCOME

. D . HOUS ING The general Qow of the model is depicted in Figure II. Briefly, the model unfolds as follows. The industrial sector, through employment, is linked to the national economy. The tightness of the local labor market, along with inflationary conditions, determine the level of manufacturing wages. In the next stage, employ-ment in the commercial sector and per capita personal income are simultaneously determined; their levels are dependent on industrial activity and are interdependent with each other. Finally, population of the house-owning age group is combined with local wealth and employment conditions, and national information on the Qnancial markets to determine the housing market growth. A brief description of each area follows.

0

A. INDUSTRIAL SECTOR A region's manufacturing sector, primarily its exporting industries, provide the major link between the national and regional economies. Thus, we would expect this sector to follow the national patterns given that it serves a national market. However, we expect the local industries to maintain regional characteristics as well, from the standpoint of locational decisions on the part of entering/exiting manufacturing concerns, In modelling manu-facturing employment in the PP&L service area every attempt was made to include these two aspects: linkage with the national economy and regional locational decisions .

B. COMMERCIAL SECTOR The type of services provided and products sold within the commercial sector are quite similar across different regions of the country. However, the growth of this sector within a region is heavily dependent upon the local economy. In developing the commercial employment equations, the growth in each of these sectors was compared to their breakdowns nationally.

The relative growth of the area was then compared to the relative U.S.

growth in population and per capita income.

C. WAGES, PRICES, AND PERSONAL INCOME Manufacturing average hourly earnings and total personal income for the service area are forecasted within the C.E.P. economic model, building from the employment situation in the manufacturing and commercial sectors. In addition, a forecast of local inflation conditions is developed directly from the inflation conditions of the nation.

D. HOUSING SECTOR The growth in the housing stock is an important determinant of residential sales. Therefore, in the economic model, we explictly model household formations in the service area. In developing this sector we have a choice of two available data series, household permits from the federal government and new dwelling unit statistics from PPaL records.

The dwelling unit data, considered more reliable and easier to monitor, was used. The long-run demand for housing is hypothesized to be of the population of the house-owning age group and the level a'unction of household wealth.

IV. RESIDENTIAL SECTOR The residential model has been developed to forecast sales to the two major classes of residential service; viz., electrically heated homes and general residential.

In doing so the model is divided into two blocks:

o CUSTOMER BLOCK o USAGE BLOCK

In the customer block the number. of residential customers under each of the services is determined. The'usage block determines the average kWh usage per customer under each of the, services. Total residential usage is obtained by summing the product of customer stock and per customer usage in each of the groups.

Customer Block Total residential customers in any period is equal to the number in the previous period, plus the new units coming on, less the depreciation of the existing stock.

In estimating our usage per customer equations, the impact of the following determinants was measured.

o HOUSEHOLD INCOME o PRICE OF ELECTRICITY o PEOPLE PER HOUSEHOLD o WEATHER CONDITIONS o CONSERVATION EFFORTS Figure III shows the relationships that are considered in modelling this sector.

V. COMMERCIAL SECTOR The Commercial Sector presents a difficult modelling task to the forecaster.

Over the past 10 to 15 years it has shown steady growth, becoming an increasing portion of total sales; yet little information is available over this interval on the type of load served. The best that can be done in lieu of commercial surveys and expanded data collection is to include in, the model those economic indicators that best depict the growth of these customers. The modelling task is not one of obtaining satisfactory summary statistics, they come rather easily, but rather to be sure that the real determinants and indicators of growth are in the'model. In addition to the overall growth, the price of electricity, weather conditions and conservation are considered important determinants of sales and are included.

Sales to the commercial sector are collected by four major classes:

o Wholesale and Retail Trade o Financial and Personal Services o Other Commercial o Small Commercial The general outline of estimating this sector is exhibited in Figure IV.

INDUSTRIAL SECTOR The Industrial Model was developed to forecast KWH sales to fourteen major industrial classes. The sales forecast for the industrial sector is'the aggregation of these fourteen cia'sses, the breakdown of which is given in the table below and the flow diagram. shown as Exhibit V.

SUMMARY

In summary, the PP5L Econometric Model forecasts th'e short and long-term kWh consumption for the major consuming sectors, in the. PPaL Service Area. It utilizes forecasts from the DRI Macro Model together with regional economic, demo-graphic, and climatic conditions-to determine a scenario of the service area economy.

Assumptions about the price of electricity and competing fuels, weather expectations, the working age population, and technological changes are then made, from which point the model produces a kWh forecast. Outlooks are also prepared by PPaL Energy Consultants.

In the residential sector, the model forecasts kWh sales for Electrically Heated Homes and General Residential Service. For both of these classes, sales is the product of the number of customers and usage per .customer. The number of customers is a function of employment in the service area, real disposable income, new dwelling units, the price of electricity and competing fuels, and new mortgage commitments. Usage per customer is determined, for the most part, by the real price of electricity, real disposable income, and weather. The model, which develops the mathematical relationships among these variables, then fore-casts residential sales.

Commercial sales, which are segregated into four categories, are a function of commercial employment in the service area, real disposable income, the real price of electricity, and weather. The growth in commercial demand is positively related to the first two variables while negatively related to the third. By solving a series of equations, the model'determines the kWh consumption in the commercial sector.

The forecast of industrial sales makes use of estimates of industrial output, which in turn is a function of manufacturing employment. Manufacturing employment, by two-digit SIC Codes in the PPaL service area depends upon current levels of employment and the level of production for a particular industry. Industrial output in our service area is defined as the Federal Reserve Board Production Index times the ratio of PPSL employment to U S. employment. Sales to the fourteen industrial

~

SIC groups are mainly determined by finding the relationship of kWh sales to service area industrial output, the relative price of electricity to fuel oil, the relative price of electricity to natural gas, and any technological changes that might occur.

No model, regardless of how well it is specified, will forecast perfectly.

There will be exogenous events, such as large new loads or changes in company or government policy, that the model is unable to pick up. In these cases, the results of the model can be modified to the desired level by judgment.

VIII. PEAK LOAD FORECAST In order to adequately provide for our customers'emands for electricity, adequate generating capacity must be available. The amount of capacity required is determined by forecasting summer and winter system peak loads for ten to fifteen years into the future. Summer and winter system peaks are forecasted because it is during these periods that the greatest demands are made on our system. Air conditioning load causes the summer peaks, and lighting and space heating loads are responsible for those in the winter.

PPEL's estimating procedure produces summer and winter system peak loads by developing the contribution made by each rate class. The term "rate class" means all customers served under similar rate schedules. The sale of energy forecast developed by revenue classes is reallocated to rate classes using observed historical relationships. Load study data is then brought into the estimation process. Our load studies are designed to determine the load characteristics of a specific class of service. When meters are of the watt-hour type, stratified random samples of customers within kilowatt-hour ranges are used. In the case of most general service sample customers (up to 7000 kw with demand meter billing), load factor ranges within each rate class are used.

Larger commercial and industrial customers are studied individually. Daily load curves for the days of summer and winter system peak are derived for every stratum of each rate class for an average customer.

For customers studied by kilowatt-hour ranges, demand per customer data for each stratum of each rate class are multiplied by the number of customers in the universe of that stratum to obtain a universe daily load curve. The number of customers in a stratum is obtained from the Company's bill frequency distributions. This can also be done for years other than the load study test year because the load characteristics of a kWh or load factor stratum remain fairly constant with only the number of customers in a stratum changing from year to year.

Daily load curves for load factor stratum are stated as ratios of customer monthly maximum demand. These are applied to the sum of customer demands in each load factor stratum as determined from an hours-use distribution to obtain the universe daily load curve.

For an historical year the strata of a given rate class are added together to form the daily load curve for the universe of that rate class. The rate class load curves for the days of summer and winter system peak of a given year are corrected for losses to the net generation level and added together to form the summer and winter load curves for the system. The result is checked against actual peak loads.

Using these techniques we have developed rate class contributions to summer and winter system peaks historically for selected hours of the day. The ratio between class contribution to system peak and annual sales to that class is calculated for each rate class at the time of summer and winter system peak, for every historical period analyzed. The trend of this ratio for either a summer or a winter syst'm peak is fairly constant over time. For a given class the trend of this ratio for the time of both summer and winter system peak is projected through time. By applying the appropriate ratios to the predicted annual sales of any future year, that class'ontribution to summer and winter peak is forecasted. The system peak for a specific time period is obtained by adding together the projected class contributions to system peak.

SUSQU EH ANNA SES-ER-OL contaminated by airborne radioiodine is a potential source of exposure. Samples from milk animals are considered a better indicator of radioiodine in the environment than vegetation.

the census reveals milk animals are not present or are If unavailable for sampling, then veqetation may be sampled.

The 500-sq. ft. garden, considering 20% used for growing green leafy vegetables and a vegetation yield of 2 kg/m> will produce the 26 kq/yr assumed in ~Re ula~tor Guide 1.109 (March 1974) for child consumption of leaf y veqetation. The option to consider the garden to be at the nearest residence is conservative and those locations may be used to calculate doses due to radioactive ef fluent releases in place of the actual locations which would be determined by the census.

The permission of deviations from the sampling schedule is based on the recognition of unavoidable practical difficulties which in the absence of the permitted deviations would result in violation of the specifications.

The requirement for the participation in the EPA cross-check program, or similar program, is based on the need for independent checks on the precision and accuracy of the measurements of radioactive material in environmental monitorinq in order to demonstrate the validity of the results.

~Re oeting Requirement A. Annual Environmental Operatinq Report, Part B, Radiological.

A report on the radiological environmental sur veillance proqram for the previous calender year shall be submitted to the Director of the NRC Regional Office (with a copy to the Director, Office of Nuclear Reactor Requlation) as a separate document in May of each year.

The period of the first report shall begin with the date of initial criticality The report shall include a

. summary (format of Table F-1, Environmental Monitoring Program Summary) interpretations, and statistical evaluation of the results of the radiological environmental surveillance activities for the report period, includinq a comparison with operational, controls, preoperational studies (as appropriate) and previous environmental surveillance reports and an assessment of the observed impacts of the station operation on the environment.

In the event that some results are not available the report shall be submitted noting and explaining the reasons for the missinq results. The missing data shall be submitted as soon as possible in a supplementary report.

S US QU EHA N NA S ES-ER-OL The reports shall include either explicitly or by reference to other documentation, the following: a summary description of the radiological environmental monitorinq program including sampling methods for each sample type, size and physical characteristics of each sample type, sample preparation methods analytical methods, and measurinq equipment used; a map of all sampling locations..the results of the land use censuses and the results of the Applicant's participation in the Environmental Protection Agency's Environmental Radioactivity Laboratory Intercomparisons Studies (Crosscheck) Proqram.

B. Non-routine Radiological Fnvironmental Operatinq Reports If a confirmed measured radionuclide concentration in an environmental sampling medium averaged over any quarter samplinq period exceeds the reporting level given in Table F-4, Reportinq Levels. for Non-Routine Operation, a written report shall be submitted to the Director of the NBC Regional Office (with a copy to the Director, Office of Nuclear Reactor Regulation) within 30 days from the end of the quarter. A confirmatory reanalysis of the original, a duplicate or a new sample may be desirable, as appropriate. The results of the confirmatory analysis shall be completed at the earliest time consistent with the analysis, but in any case within 30 days except in the case of the strontium analysis. Zf it can be demonstrated that the level is not a result of station effluents (i.e., by comparison with control station or preoperational data) a report need not be submitted, but shall be discussed in the annual report.

If radionuclides other than those in Table -F-4 are detected and are due from station effluents, a reporting level is exceeded if the potential annual dose to an individual is equal to or greater than the design objective doses of 10 CFR Part 50, Appendix I This report shall include an evaluation of a release conditions, environmental factors or other aspects necessary to explain the anomalous result

Acceptable detection capabilities for thermoluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13, July 1977.

Indicates acceptable detection capabilities for radioactive materials in environmental samples. These detection capabilities are tabulated in terms of the minimum detectable level (MDLs). The NOL is defined, for purposes of this Table, as that concentration of radioactive material in a sample that will yield a net count which is different from the background count by three times the standard deviation after background count.

For a particular measurement system (which may include radiochemical separation):

3 00 Sb MDL =

E x V x 2.22 x Y x exp(-X t)

where, NOL is minimum detectable level as defined above (as pCi per unit mass or volume)

Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)

E is the counting efficiency (as counts per disintegration)

V is the sample size (in units of mass of volume) 2e22 is the number of disintegrations per minute per picocurie Y is the fractional radiochemical yield (when applicable) is the radioactive decay constant for the particular radionuclide is the elapsed time between sample collection and counting The value of S used in the calculation of the NOL for a particular measurement system should e based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicated variance. In calculating the MDL for a radionuclide determined by gama-ray spectrometry, the background should include the typical contributions of other radionuclides normally present in the sample (e.q., potassium-40 in milk samples). Typical values of E,V,Y, and t should be used in the calculation.

It should be recognized that the NOL is defined as ~a riori (before the fact) limit representing the capability of a measurement system and not as f t f ill i f p
