RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL (REMM)
INTRODUCTION The Radiological Environmental Monitoring Manual (REMM) required by Specifi-cation 3.20.F.1 of the Cooper Nuclear Station Radiological Technical Specifications, describes the Radiological Envorionmental Monitoring Program for Cooper Nuclear Station (CNS). The radiological environmental monitoring progran shall be conducted in accordance with the REMM.
A radiological environmental monitoring program, approved by the Nuclear Regul-atory Commission (NRC), was initiated at CNS before initial criticality was attained on 21 February 1974. The program monitors radiation levels in the air, terrestrial, and aquatic environments. Most samples are collected by Nebraska Public Power District (NPPD) personnel. However, all samples are shipped for analysis to a contractor's laboratory where there exists the special facilities required for measurements of extremely low levels of radioactivity.

PROGRAM DESCRIPTION A.
SAMPLE DESCRIPTION Background Radiation Ambient levels of external radiation are measured at selected locations within an approximate 10-mile radius of the plant by exposing thermoluminescent dosi-meters (TLD) for quarterly time periods. Selection of locations and periods of exposure are based on prevailing winds and anticipated radiation levels to provide suitable measurements for evaluation of probable radiation doses to the environs surrounding the plant location.
Soil Soil samples consist of approximately 2 kg. of soil obtained by inserting a tubular sample template into the earth to a depth of approximately 6 inches and removing the enclosed soil to a suitable container.
Vegetation - Food and Feed Crops Food and feed crop samples consist of approximately 2 kg. of the consumable portions of the food or feed crop being grown at the designated sample location.
Vegetation - Garden Crops Garden crop samples consist of approximately 2 kg. of the edible portions of garden vegetables (usually tomatoes, sweet corn, and cabbage, when available) taken from family gardens at the designated sample stations within a 5-mile radius of the plant.
Vegetation - Feed and Forage - Beef Producers and Nearest Hilk Producers Approximately 2 kg. of forage will be sampled during the pasture season where milk and/or beef cattle are raised at the designated sample stations within an approximate 5-mile radius of the plant. These forage samples will be taken at the accelerated frequency rate, during peak pasture season, as shown in the sampling schedule. When the beef and milk cattle are not on pasture, sampling will consist of approximately 2 kg. of feed, sampled at the less frequent sampling frequency as shown in the sampling schedule.
When coupled with the use of trans fer coefficients and intake figures, a reliable monitoring program for Cs-137 uptake in beef cattle is obtained.
The average daily cattle intake Cs-137 will be estimated from the forage sampling data as follows:
Average Cs-137 concentraction pCi x 0.03 kg. dry matter intake in forage-dry matter kg.
kg. animal body weight x 500 kg. body wt. = mean daily cattle intake of Cs-137 gCi day 2273 252 e
The average beef concent; ations may be estimated for the steady state (equili-brium) condition using the feed to meat transfer coefficient (T.C.) proposed by Johnson, Tyler and Ward (J. An. Sci 29,695,1969) for pasture conditions.
T.C. = pCi/kg meat (wet basis) = 0.02 pCi/ day intake Therefore the average beef concentration of Cs-137 in pCi/kg. =
T.C.
[pci/ day intake]
(wet basis)
In the event the average beef concentration of Cs-137, as determined above, exceeds 500 pCi/kg. (which is approximately twice the concentration present in beef due to Cs-137 fallout) beef cattle wil? be sampled directly.
Vegetation - Feed and Forage - Commercial Milk Producers These feed and forage samples will consist of approximately 2 kg. of the feed or forage that the milk cows have been consuming just prior to producing the milk sample.
Apples Since apples are grown for commercial market in the area of the plant at nearby locations, the fruit from these orchards are sampled. These samples will be of approximately I kg. each.
Airborne - Particulates and Halides Continuous air sampling is performed at selected locations within an approximate ten mile radius of the plant.
Locations have been selec' ed on the basis of prevailing winds and existing populated areas for evaluation of probable exposure to airborne particulate and halide radioactivity of the environs surrounding the plant location. The collection devices for iodine will contain potassium iodide impregnated charcoal or equivalent, and be constructed and operated so as to retain quantitatively the iodine in the air passing through the devi_Se.
Sensitivities will be such that an iodine concentration of 4
2.0 x 10 uCi/cc may be measured. Appropriate analyses of particulate filters and halide collection devices are performed on all samples in accordance with accepted techniques and nuclides of interest.
River Water Sampling of the Missouri River water is performed at the designated location extending from approximately three miles above the plant intake structure to approximately two to three miles downstream from the station.
Aquatic Biota-Fish At least 5 kg. of each of two species at each location are collected from the Missouri River at locations from one to three miles upstream and one to three miles downstream from the plant. An attempt is made to include bottom-feeding types as well as middle-or top-feeding types in the species collected from each sampling location.
2273 253 Aquatic Biota-Vegetation Rooted aquatic plants and/or algal growth on submerged natural surfaces in littoral locations of the Missouri River are sampled when available during scheduled collection times at selected locations from immediately upstream to two miles downstream f rom the plant.
Ground Water Sampling of ground water is performed from the plant well water supply header and from a municipal water supply well.
Milk (Nearest Producers)
During the season the cows are on pasture, samples of fresh milk will be obtained at the frequency specified in the sampling schedule from cows at locations that may be significantly affected by emissions from the Cooper Station (i.ee, where the calculated dose to a child's two gram thyroid using NRC models and assumptions is equal to or exceeds 15 mrem /yr) and analyzed for their radioiodine content, calculated as iodine-131.
Analysis will be carried out within eight days (one I-131 half-life) of sampling.
Suitable analytical procedures will be used to determine the radioiodine content to a sensitivity of 0.5 picocuries I-131 per liter of milk at the time of sampling.
Counting statistics will be such that the standard deviation (one sigma confidence level) of the net counting rate will be 10% or less. Overall error of the analysis will be within + 25%. Results will be reported, with associated calculated error, as picocuries of I-131 per liter of milk at the time of sampling.
Milk Milk is sampled from commercial milk producers within an approximate ten mile radius of the station. In the selection of milk sampling locations, an attempt has been made to select producers within areas of potential station influence with well established herds, who are most likely to remain in the business of milk production during succeeding years of station operation.
Eggs Since eggs are a common edible farm product in the area, egg samples (two dozen per sample) are taken at the designated egg sample stations.
Bases:
The limiting conditions for operation of CNS include restricting environmental effects due to the operation of CNS (including exposure to the population) in unrestricted areas surrounding the CNS plant site to within limits in NRC Regulations 10 CFR - parts 20, 50 and 100. This monitori gram thereby supplements the radiological effluent monitoring program by v.
f ng that the i
measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways.

LAND USF CENSUS A land use ce tsus shall be conducted annually and shall identify the location of the nearest.irden* that is greater than 500 square feet producing fresh leafy vegetables, the location of the nearest milk animal, and the location of the nearest resident in each of the 16 meteorological sectors within three miles of the Station.
The land use census shall be conducted at least once per 12 months between the dates of (June 1 and October 1), by door-to-door survey, aerial survey, or by consulting local agriculture authorities.
The land use census shall be used to identify location (s) which yields a calculated dose or dose commitment (via the same exposure pathway) greater than at a location from which samples are currently being obtained in accordance with the REMM. With a land use census identifying a location (s) which yields a calculated dose or dose commitment greater than the values currently being calculated in Specification 4.20.C.3a initiate a change in the REMM pursuant to Specification 6.8.2.
The results of the land use census shall be included in the Annual Radiological Environmental Operating Report.
Bases:
This specification is provided to ensure that changes in the use of unrestricted areas are identified and that modifications to the monitoring program are made if tequired by the results of this census.
This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg./ year) of leafy vegetables assumed in Regulator Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used, 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of two kg./ square meter.
- Broad leaf vegetation sampling may be performed at the site boundary in the direction sector with the highest D/Q in lieu of the garden census.
2273 262 D.
INTERLABORATORY COMPARISON PROGRAM Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program.
A vendor is utilized to analyze radiological environmental samples collected for the C.N.S. Radiological Environmental Program. This vendor is required by NPPD to participate in an Interlaboratory Comparison Program.
With analyses not being performed as required above, report the corrective action taken to prevent a recurrence to the Commission in the Annual Radiological Environmental Report.
A brief summary of results obtained as part of the above required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Report.
Bases:
The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of a quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

TABLE NOTATION a
The LLD is the smallest concentration of radioactive material in a sample that will be detectel with 95% probability with 5% probability of falsely concluding that a blank observa) ion represents a "real" signal.
For a particular measurement system (which may include radio-chemical separation):
4.66 s LLD =
b E. V. 2.22. Y. exp(-AAt) where LLD is the lower limit of detection as defined above (as pCi per unit mass or volume) is the standard deviation of the background counting rate or of the counting rate of a s h blank sample as appropriate (as counts per minute)
E is the counting efficiency,(as counts per transformation)
V is the sample size (in units of mass or volume) 2.22 is the number of transformation per minute per picocurie Y is the fractional radiochemical yield (when applicable)
A is the radioactive decay constant for the particular radionuclide At is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of s used in the calculation of the LLD for a detection system shall be based on the g
actual observell variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD fcr a radionuclide determined by gamma-ray spectrometry, the background shall include the typical contributions of other radio-nuclides normally present in the y
samples (e.g., potassium-40 in milk samples).
U Analyses shall ba performed in such a manner that the stated LLD's will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLD's m
unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.
