LA CROSSE BOILING WATER REACTOR l ENVIRONMENTAL RADIOACTIVITY SURVEY v

INTRODUCTION This report covering the calendar year 1987 is prepared under U.S.

Nuclear Regulatory Commission Contract NRC 30-03-647 by the State of Wisconsin, Department of Health and Social Services, Section of Radiation Protection. Results of environmental radioactivity monitoring are listed in tabular form. The data presented consists of duplicative split sample analysis conducted by the state radiation protection laboratary or subcontractor and the licensee. A brief description of sample collection techniques and analytical procedures conducted by the state laboratory is also given. A sample collection summary for 1987 is included in Table 6. The sample summary includes type and number of samples collected as well as the range of reported actisities for each type of sample analysis.

The La Crosse Boiling Water Reactor ceased operation on April 30, 1987 and has applied to the Nuclear Regulatory Commission for a possession-only license under 10 CFR Part 50. The etnvi ronmen t al monitoring programs conducted by the La Crosse Boiling Water Reactor and State of Wisconsin, Department of Health and Social Services, Section of Radiation Protection have remained the same during this reporting time period of January 1 through December 31, 1987.

SAMPLING TECHNIQUES Whenever possible a split sample is taken inorder to obtain a valid comparison between WI DHSS and LACBWR results. Split sampling involves the thorough mixing of a sample into a homogeneous mixture that is than split between WI DHSS and LACBWR.

Direct Radiation Thermoluminescent Dosimeters (TLD's)

Continuous monitoring of direct radiation is performed quarterly using l thermoluminescent dosimeters. The dosimeters are placed at 29 '

locations in the area of the La Crosse Boiling Water Reactor (LACBWR) nuclear power plant.

Air S_amples ,

l Continuous air samples are collected weekly from two stations. Air i particulate samples are collected on 47 mm. glass fiber filters. Air l

. iodine samples are collected using charcoal absorbers mounted downstream of the air particulate filters. The nominal sampling rate is 1-2.5 cubic feet of air per minute depending on the air pump used.

1

Surface Water A split sample is collected monthly at a point close to the dischargo of the LACBWR eff1'uent channel, 0.1 mile W. This sample is a grab comple and is collected while the plant is discharging wastewater to the channel. A background surface water sample is also collected -

monthly from Lock and Dam #8, 0.7 mile N.

3 Milk A raw, split milk sample le collected monthly from one of three local farms located in the Genoa, Wisconsin area.

Sediment Sediment is collected from three locations in the Mississippi River channel on an annual basis.

Fish Game and scavenger fish are collected periodically from locations in the Mississippi River near the LACBWR nuclear power plant.

Food Products A blended sample of mixed vegetables is collected from local gardens.

ANALYTIC?t PROCEDURES The procedur given are condensed to present only the basic method.

The analysf of the samples has been subcontracted to the State Laboratory or Hygiene. A detailed description of the procedures used ,

is available from the State Laboratory of Hygiene.

l Air Particulate _ Samples - Beta Gamma Place the 47 mm. glass fiber filter on a 2-inch stainless steel planchet. Beta count in an external gas flow proportional counter.

Calculate activity correcting for counter efficiency. j Air Particulate Samples - Gamma The quarterly composite of air particulate filters is placed on a Ga(Li) detector and the gamma spectrum is collected. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay. .

Surface Water - Alpha, Beta Gamma Filter a 500 ml. aliquot of sample. Evaporate filtrate in a 2-inch 2

i f

stainless steel planchet. Place filter paper in a 2-inch stainless l steel planchet and dry at 103 degrees Celsius. Beta and alpha count the soluble and insoluble portions .i n an external gas flow proportional counter. Calculate activity correcting for counter effjciency and self-absorption.

5 Surface Water - Gamma Isotopic 9

. A 3.5 liter sample is placed in a Marinelli beaker and analyzed on a GeLi detector. Scan the gamma spectrwa for any peaks and print out regions of interest which would include possible plant attributable radionuclides. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

Surface Water - Iodine 131 Chemical Extraction A stable iodine carrier is added to a 2 liter sample of raw milk. The sample is passed through an anion exchange column and the iodine is removed from the resin by batch / extraction using Na001. After reduction to elemental iodine by hydroxylamine hydrochloride, the iodine is extracted into carbon tetrachloride reduced with bisulfite, and back extracted into water. The iodine is precipitated as palladous lodide with the chemical yield determined gravimetrically and counted in an external gas flow proportional counter. Calculate activity correcting for counter efficiency and for decay.

Surface Water - Strontium 89 and Strontium 90 Strontium and yttrium carriers are added to the surface water samples.

The procedure follows through a series of chemical separations whereby all in erfering substances are removed. Calcium is removed by precipitating strontium and barium by nitrate precipitation thereby leaving the calcium in solution. Radium is removed by co-precipitation with barium as a chromate. The ingrowing yttrium is separated from the parent strontium through the use of hydroxide scavenging. The purified strontium is converted to a carbonate and beta counted in an external gas flow proportional counter. After two weeks ingrowth yttrium-90 is separated from the strontium carbonate via a series of hydroxide precipitations and finally converted :o an oxalate and beta counted in an external gas flow proportional counter.

The strontium-90 activity is calculated from the yttrium-90 count and the strontium-89 activity is calculated using the previous calculation for strontium-90 as well as the total strontium activity from the strontium carbonate counting.

Vegetation o_r Food Product - Alpha, Beta and Gamma Isotopic Dry sample at 110 degrees Celsius, grind and weigh into a stainless steel planchet. Beta and alpha count in an external gas flow

. proportional counter. Calculate activity correcting for self-absorption and counter efficiency.

The food product sample is finely chopped. The sample is packed to the 500 mi mark of a 500 ml Marinelli beaker, weighed and counted on a 3

Ge(L1) detector. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay, a

Soil or Sediment -Alpha, Beta and Gamma Isotopic Dry sample at 110 degrees' Celsius, grind and weigh into a stainless -

steel planchet. Beta and alpha count in an external gas flow proportional counter. Calculate activity correcting for self-absorption and counter etficiency.

The dried soil is added to a 500 m1 Marinelli beaker, weighed and counted on a Ge(Li) detector. Scan the gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

Milk - Gamma Isotopic Procedure same as for Surface Water.

Milk - Iodine 131 Chemical Extraction Procedure same as for Surface Water.

Milk - Strontium 90 Strontium and yttrium carriers are added to milk which has been aged two to four weeks. A one liter sample is passed successively through cation and anion exchange columns. The yttrium is eluted from the anion resin with hydrochloric acid, precipitated as yttrium oxalate,  !

filtered and weighed to determine chemical yield. Beta count in an external gas flow proportional counter. Calculate the activity correcting for counter efficiency and for decay.

Fish - Gamma Isotopic An edible portion is placed in a 500 ml. Marinelli beaker. Place the sample on a GeLi detector and collect the gamma spectrum. Scan the i gamma spectrum for any peaks and print out regions of interest which would include possible plant attributable radionuclides. Calculate the activity for isotopes in the regions of interest, regardless if they are above or below the minimum detectable concentration, correcting for counter efficiency and for decay.

Direct Radiation Thermoluminescent dosimeters are supplied by the U.S. Nuclear Regulatory Commission. The err <osed TLD's are shipped to NRC Region I and are read by the Commission.

QUALITY ASSURANCE The analysis of the samples is performed under subcontract with the State Laboratory of Hygiene (SLH). SLH maintains its own quality assurance program which was also reviewed by the NRC in January, 1985.

. Analytical procedures provide for routine replicate analyses to verify methods and instrument operation. Traceable sources are used to l regularly calibrate the counters and daily performance checks are made between calibrations. In addition, quality centrol charts are maintained on the counters.

SLH participates in the EPA Cross Check program. The quality assurance program that the SLH participates in include analysis of blind samples, air filters, food, milk, gamma in water, alpha-beta in water, iodine in water, strontium in water and tritium in water. The EPA Cross Check code for SLH is "AF". A complete listing of the EPA Cross Check results for 1986 and 1987 is included in Table 8.

SENSITIVITIES AND ERROR -

WISCONSIN DHSS Following the recommendations of the Health Physics Society, detection limits will be expressed as a minimum detectable concentration (MDC).

The minimum detectable concentration or MDC is an "a priori" estimate of the capability for detecting an activity concentration by a given measurement system, procedure, and type of sample. The MDC should not be viewed as an absolute activity concentration that can or cannot be detected. Minimum detectable concentrations (MDC) are based on the analysis performed and for gamma isotopic analysis have been calculated for a zero decay time. A listing of the WI DHSS MDC values is included in Table 6.

The WI DHSS definition for minimum detectable concentration follows closely the equation for the lower limits of detection as defined in the NRC contract NRC-30-83-647. Activities defined by the equation for MDC will be used in this report.

The MDC for each radioisotope has been calculated from the following equation:

4.66 sb MDC =

'E

  • V
  • 2.22
  • y
  • S
  • exp(-dt)

Where:

MDC is the "a priori" lower limit of detection as defined above, as picoeuries per unit mass or volume, 5

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 or volume, ,

2.22 is the number of disintegrations per minute per picoeurie, Y is the fractional radiochemical yield, .when applicable, S is the self-absorption correction factor, d is the radioactive decay constant for the i particular radionuclide, and i t for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting, )

i Guidelines adopted by the U.S. Environmental Protection Agency are '

used in the reporting of specific analyses. Results from specific l analyses will be reported whether the results are negative, zero, or positive. Caution should be exercised in the interpretation of individual negative values. While a negative activity value does not have physical significance, it is significant when taken together with other observations which indicate that the true value of a distribution is near zero. This procedure will allow all of the data to be reported and will allow a statistical evaluation without an arbitrary cutoff of small or negative numbers. An estimation of bias in the nuclide analyses as well as a better evaluation of distributions and trends in the environmental data is then possible.

It is important when reviewing the data in the following tables to compare the reported result to the actual minimum detectable concentration (MDC) for that analysis.

Results for specific analyses will be reported as an activity followed by an error term for that analysis. The error term is a plus or minus counting error term at the 2 sigma (95%) confidence interval and is printed as (+/-).

SENSITIVITIES -

LACOWR Lower limits of detection (LLD) or minimum detectable activity (MDA) '

as reported by LACBWR are defined in their manual LACBWR, HEALTH &

SAFETY DEPARTMENT PROCEDURE, LACBWR ENVIRONMENTAL MONITORING PROGRAM.

The method for calculating the LLD and a representative table of LLD's -

for LACBWR is included in this report. In most cases, reported activities for LACBWR are less than the required Nuclear Regulatory Commission LLD's.

In the WI DHSS gamma isotopic analysis bery111um-7 (Be-7) was detected in all composites from both the indicator and control sites.

Bery111um-7 (Be-7) is a naturally occurring radioisotope that is constantly produced through nuclear reactions between cosmic rays and 4

nuclei in the atmosphere. All other radionuclides were below their respective MDC for the 1st, 2nd. 3rd and 4th quarter composites.

, LACBWR does not report naturally occurring radioisotopes and no comparison can be made-for the bery111um-7 (Be-7) reported by WI DHSS.

All of the reported radioisotopes by LACBWR for the monthly composites were at trace activity levels and all were less than the respective WI DHSS MDC.

At the observed lower levels of activity, the WI DHSS and LACBWR data are comparable in the gross beta and gamma isotopic analysis on the air particulate samples. Influence by the LACBWR nuclear facility on air quality is not evident when comparing the data from the indicator and control sites.

Air Iodine Air iodine samples are taken at the same sites as the air particulate camples.

A summary of reported air iodine activities for WI DHSS and LACBWR is included in Table 6. Results from the individual sample analyses are listed in Tables 9-12.

All reported WI DHSS and LACBWg air iodine measurements were below the required NRC LLD of 0.07 pC1/M for both the indicator and the control sites.

Surface Water The surface water samples are split samples taken as a grab sample on a monthly basis. The discharge channel is taken as the indicator site and Lock and Dam #8 is taken as the control site.

A summary of reported activities by WI DHSS and LACBWR from the monthly surface water samples is included in Table E. Disagreements in the reported WI DHSS and LACBWR results are listed in Table 7.

Results from the individual sample analyses are listed in Tables 15-18.

The WI DHSS and LACBWR reported activities from the monthly surface water samples taken at the control station, Lock & Dam #8, are all at background levels. All reported activities by WI DHSS and LACBWR for gamma isotopic and tritium analyses were less than the respective WI DHSS minimum detectable concentration (MDC) or LACBWR minimum detectable activity (MDA).

Analysis of the surface water samples taken from the indicator site, discharge channel, by WI DHSS detected small activities of cobalt-60 (Co-60), manganese-54 (Mn-54), cesium-137 (Cs-137), s11ver-110 (Ag-110) and tritium (H-3). LACBWR analysis detected small activities of  !

manganese-54 (Mn-54), cobalt-60 (Co-60), cesium-137 (Cs-137),

ruthenium-103 (Ru-103), cerium-141 (Ce-141) and tritium (H-3).

  • Reported activities above the WI DHSS MDC or the LACBWR MDA levels ,

were comparable except for the disagreements listed in Table 7. The

  • WI DHSS and LACBWR sample analysis reports were reviewed for possible problems in the sample analysis but no problems were noted.

All activities reported by either WI DHSS or LACBWR are below the standards for uncontrolled areas as specified in ICRP Report No.2 or 10 CFR 20.

Fish Both LACBWR and WI DHSS analyze the same samples with LACBWR first performing its analysis and then WI DHSS.

A summary of reported activities by WI DHSS and LACBWR from fish samples is included in Table 6. Results from the individual sample analyses are listed in Tables 19-20.

From the WI DHSS gamma isotopic analysis only naturally occurring potassium-40 (K-40) was detected in all samples.

LACBWR does not report naturally occurring radioisotopes. The reported LACBWR activities for zine-65 (Zn-65) and cobalt-60 (Co-63) were all less than the respective WI DHSS MDC.

At the low level of reported activities the WI DHSS and LACBWR data are comparable.

Bo_ttom Sediments Both WI DHSS and LACBWR analyze the same samples with LACBWR first performing its analysis and then WI DHSS.

A summary of reported activities by WI DHSS and LACBWR from bottom sediment samples is included in Table 6. Results from the individual sample analyses are listed in Table 21.

The gamma isotopic analysis of the upstream sample, Lock & Dam #8, by WI DHSS detected only naturally occurring potassium-40 (K-40) and naturally occurring radioisotopes from uranium and thorium decay series. Analysis by LACBWR detected only trace activities of cesium-137 (Cs-137). All reported activities by WI DHSS or LACBWR for the upstream site were less than the required NRC LLD's.

The highest act!-rities for both WI DHSS and LACBWR Were detected at the discharge point wi th' cobalt-60 (Co-60) and cesium-137 (Cs-137) 10

predominating and smaller detected activities for cesium-134 (Cs-134) zinc-65 (2n-65) and manganese-54 (Mn-54). Reported WI DHSS data from the discharge point for 1985-1987 for cobalt-60 (Co-60) and cesium-137 (Cs-137) is listed in Table 4. The discharge point is not necessarily the best site to observe trends of accumulated radioactivity versus time. From correspondence with Dairyland Poaor Cooperative environmental department personnel, their observations are e that the discharge point has a very small area to colle'et bottom

, sediment with larger aggregate predominating and that it also has a high scouring rate. The discharge site, however, is probably the only point available in the immediate area due to the large amount of riprap in the area.

From the downstream site, boat launch, WI DHSS detected activities above MDC values for naturally occurring potassium-40 (K-40) and naturally occurring radioisotopes from uranium and thorium decay series. LACBWR reported small activitfes for manganese-54 (Mn-54)and cesium-137 (Cs-137) which are less than the respective WI DHSS MDC nr NRC LLD.

The reported activities by WI DHSS and LACBWR are comparable for all three sites.

Milk The milk samples are obtained as grab samples on a monthly basis and are then split for analysis.

A summary of reported activities by WI DHSS and LACBWR from milk samples is included in Table 6. Results from the individual sample analyses are listed in Table 22.

WI DHSS detected naturally occurring potassium-40 (K-40) in all samples and cesium-137 (Cs-137) in one sample in its gamma isotopic analysis of the milk samples. All activities for iodine-131 were below its MDC of 0.40 pCi/1.

l l

l LACBWR reported activities for cesium-137 (Cs-137) in four samples. l All other radionuclides were below the respective LACBWR MDA. LACBWR does not report naturally occurring radioisotopes and a comparison is .

not possible with the WI DHSS data. I l

At the low level of reported activities the WI DHSS and LACBWR data ,

are comparable.

4 The reported data by WI DHSS for 1987 is comparable to data reported

  • for previous years. Influence by the LACBWR facility in the milk pathway is not apparent from the milk sa.nples analyzed by either WI DHSS or LACBWR.

Vecetation - Food Products A split sample of food products was taken from two local farms. A blended sample of mixed vegetables was collected from each farm.

A summary of reported activities by WI DHSS and LACBWR from the food product sample is included in Table 6. Results from the individual sample analyses are listed in Table 23. ,

i WI DHSS detected only naturally occurring potassium-40 (K-40) above its MDC in its gamma isotopic analysis of the food product sample.

Activities for iodine-131 (I-131) were below its MDC of 60 pCi/kg.

LACBWR does not report naturally occurring radioisotopes and no other radioisotopes were reported above the respective LACBWR MDA.

The WI DHSS and LACBWR results are comparable and influence by the LACBWR facility is not evident in food product samples, i

Dose to an Average Individual Dose calculations for gaseous and 11guld effluent releases were performed according to the mathematical models illustrated in USNRC g Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating e Compliance with 10 CFR Part 50, Appendix I". The doses, listed in

, Table 5, were calculated for the average exposed individual for WI DHSS samples with activities greater than MDC.

The dose to an average individual from exposure to bottom sediments (discharge channel) are due specifically to the detected gamma activities of cobalt-60 (Co-60) and cesium-137 (Cs-137). The outfall site, however, is not readily accessibly for individual use for recreational purposes including either fishing or swimming.

Doses resulting from gaseous and liquid effluent releases from the LACBWR nuclear facility are in compliance with 10 CFR Part 50, Appendix I.

The dose to an average individual from the ingestion of milk are most likely due to background levels of radiation attributable to fallout from previous atmospheric nuclear tests and not to the operation of the LACBWR facility. The dose to an average individual from the ingestion of milk are due specifically to the detected strontium-90 (Sr-90) activities.

The doses listed in Table 5 are well below the state and federal standards of 500 mrem / year.

ATTACHMENT A - RADIO-ENVIRONMENTAL SAMPLE ANALYSES MAXIMUM LOWER LIMITS OF DETECTION VALUES (LLD)s - (Cont'd)

(a) Calculation of Lower Limits of Detection:

The LLD,is the smallest concentration of radioactive material in a sample that will be detected with 95:

probability with 5: probability of falsely concluding that a blank observation represents a "real" signal.

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

4.66 ab '

LLD -

E x V x 2.22 x T x Exp(-Aat)

WHERE: -

LLD is the a priori lower limit of detection as defined above (as picocurie per unit mass or volum'e)..

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). Typical values of E, V, Y, and at shall be used in the calculations.

E is the counting efficiency (as counts per transformation).

u

v. V is the sample size (in units of mass or volume).

2.22 is the number of transformations per minute per picoeurie.

Y is the fraction radiochemical, yield (when applicable).

1 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.

(b) (2,000) LLD drinking water.

(c) LLD for gamma spectrum analyses not separation and specific isotopic analysis.
