1.1 Definition of Radiological Environmental Monitorino f

Radiological environmental monitoring is the measurement of l radioactivity in samples collected from the atmospheric, aquatic,  ;

at,d terrestrial environment around the Point Beach Nuclear Plant  !

(PRNP). Monitoring radioactivity in effluent streams at or '

prior to the point of discharge to the environment is not part  ;

of the Radiological Environmental Monitoring Program.

• 1.2 Responsibilities for Procram Implementation ,

i 1.2.1 Nuclear Plant Engineering and Regulation Section Functions l

The General Superintendent and the staff of the Nuclear Plant Engineering and Regulation Section (NPERS) -

provide the Manage' r , PSNP, with technical, regulatory, licensing, and a kinistrative support necessary for the implementation of the program. The NPERS a hinistrative functions relating to the Radiological Environmental.

i c Monitoring Program fall into the six broad areas outlined

• I below.

l[

1.2.1.1 Program Scope ,

i The scope of the Radiological Environmental Monitoring Program is determined by NPERS.

L Based on the scope, NPERS prepares the program manual, including sampling procedures, and ,

revises the manual, as necessary to conform .

to changes in progran procedures and scope.

NPERS monitors the program effectiveness and compliance with Radiological Effluent Technical Specifications (RETS). In order to verify i compliance with RETS, NPERS arranges for a program audit at least once every 12 months and an audit of the analytical contractor at least once every 36 months.

1.2.1.2 Record Keeping Monthly results of contractor analyses are sent to both PsNP and NPERS. However, the analytical results maintained by NPERS are regarded as the official results. These ,

records are kept for the lifetime of the plant. '

The program involves the interaction of the Nuclear Plant Engineering and Regulation Section (NPERS), Point Beach Nuclear Plant (PSNP), Wisconsin Electric's Quality Assurance  ;

Section (QAS), and Teledyne Isotopes Midwest Laboratory (TIML).

The TIML quality assurance and quality control program is i described in the TIML Quality Assurance Program Manual'and the  !

,_ TIML Quality control Procedures Manual. copies of these manuals +

l. are maintained by NPERS and QAS. Amen &nents and revisions of l- these documents are reviewed by responsible NPERS and Q&S l personnel as they are issued. The contractor is audited by _  ;

[ Wisconsin Electric personnel periodically at intervals which do  !

I not exceed three years. The quality assurance portion of the '

audit is performed by Q&S, and the technical portion of the audit is performed by NPERS. As part of its quality control -

program, TIML participates in the environmental crosscheck  :

program operated by the Intercomparison and calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, U.S. Environmental Protection Agency, Las Vegas,  ?

Nevada.

(

Quality control for the PaNP portion of the radiological  ;

Environmental Monitoring Program is achieved by following the i procedures contained in this manual. Health Physics Technologists (HPTs) collect, package and ship environmental samples under the supervision of Health Physics Supervisors and the Health Physicist. .

They are advised by the Specialist - Nuclear Health Physics who has immediate responsibility for the overall technical operation of the environmental sampling functions. The HPTs receive classroom training as well as on-the-job training in carrying out

2.0 RADIOLOGIchL ENVIRONMENTAL MONITORING 2.1 Program overview 2.1.1 Purpose No significant or uneapected radionuclide concentrations of plant origin are espected because-each normal effluent-pathway at PaNP is monitored at or before the release point. However, the Radiological Environmental Monitoring Ptogram is conducted to verify that plant operations produce no significant radiological impact on the environment and to demonstrate compliance with applicable standards.

2.1.2 samples Sasples for the Radiological Environmental Monitoring Program are obtained from the aquatic, terrestrial and-atmospheric environment. The sasple types represent key indicators or critical pathways identified by applying sound radioecological principles to the PBNP environment.

2.1.3 Monitoring sensitivity The effectiveness of the Radiological Environmental l Monitoring Program in fulfilling its purpose depends e upon the ability to accurately determine.the nature and I origins of fluctuations in low levels of environmental -

I radioactivity. This requires a hign degree of sensitivity so that it is possible to correctly discriminate between fluctuations in background radiation levels and levels of radioactivity that may be attributable to the operation of PBNP. Therefore, personnel actively participating in-the monitoring program should make every effort to minimize the possibility of contaminating' environmental samples'and to obtain samples of the appropriate size.

2.1.4 Technical Specifications l I A copy of the P8NP Technical $pecificat Sns applicable to the Radiological Environmental Monitsting Program is

IM ated in Appendix A of this manual. These specifica- ,

l tions are part of the Radiological Effluent Technical '

l- Specifications (RETS).

I 2.2 Program Parameters f 2.2.1 Contamination Avoidance l 4

contamination prevents the accurate quantification of _!

environmental radioactivity and the correct differen-  !

tiation between fluctuating background radioactivity and levels of radioactivity attributable to the operation of P8NP. Therefore, it is necessary that all personnel -)

associated with collecting and handling radiological 1 environmental samples take the appropriate precautions  !

to minimize the possibility of contaminating the sasples.  ;

some of the precautions that should be taken and which will help to minimize contamination are listed below:  !

a. Equipment which has been on the controlled side, even if released clean, should not be used in , i conjunction with radiological environmental monitoring, I i

b, store 6ampling equipment in radiologically i clean areas only,  !

I j c. Store radiological environmental samples only a

( -in radiologically clean areas.when samples can not be shipped to the contractor on the same day they are collected,

d. Treat each sample as a possible source of contamination for other samples so as to minimize the possibility of cross-contani- i nation, l

e. Radiological environmental monitoring equipment should be repaired in clean-side shops,

f. contamination avoidance for environmental TLDs it covered in Section 2.4.2, and 1

g. Do not enter the controlled zone prior to .!

leaving to collect environmental samples. ,

i 2.2.2 Sample Size  ;

Sample size affects the sensitivity achievable in quan-tifying low levels of environmental radioactivity. ,

Therefore saspling personnel must attempt to attain the quantities of sample specified in Table 2-1. When a 1

( range is given, every effort should be made to obtain '

\- a quantity at the upper part of the range.

2.2.3 Lower Limit of Detection 1

The sensitivity required for a specific analysis of an environmental sample is defined in terms of the lower limit of detection (LLD). The LLD is the smallest concentration of radioactive material in a sasple that will yield a net count, above system background, i that will be detected with a 95% probability and have only a 5% probability of falsely concluding that'a blank i observation represents a real signal. Mathematically, ')

the LLD is defined by the formula '

4.66 S b

• E a v x 2.22 x Y a EXP(-Aat) q where LLD = the a priori lower limit of detection in picoeuries per unit volume or mass, as-applicable, S

3

= the standard deviation of the background J counting rato or the counting rate of a I

(' blank sample, as appropriate, in counts j per minute,  !

)

E = counting efficiency in counts per l disintegration, j V = sample size in units of volume or mass, as applicable, 2.22 = number of disintegrations per minute per picoeurie, Y = the fractional chemical yield as appli- 'j cable, J

A = the radioactive decay constant for the particular radionuclide, At = the elapsed time between sample collec-tion, or the end of the collection period, and the time of counting.

Typical values of E, V, Y, and At are used to calculate the LLD. As defined, the LLD is an a priori limit l representing the capability of a measuring system and i

(. not an a, posteriori limit for a particular measurement. j I

The required analyses for each environmental sample and l the highest acceptable LLD associated with each analysis  ;

- are listed in Table 2 2. Whenever LLD values lower r l- than those specified in Table 2-2 are reasonably achiev-  !

able, the analytical contractor for the radiological  !

environmental samples will do so. When the LLDs listed  !

in Table 2-2 are not achieved, a d=5cription of the l factors contributing to the higher LLD shall be reported  !

in the next PSNP Semiannual Nonitoring Report. [

2.2.4 Notification Levels  !

. The notificetion level (NL) is that measured quantity i of radioactivity in an environmental sample which, when exceeded, requires a notification of such en occurrence  :

be made to the appropriate party. Regulatory and admin- l 1strative notification levels are listed in Table 2-2. .  ;

2.2.4.1 Regulatory Notification Levels f

The regulatory notification levels listed in [

Table 2-2 represent the concentration levels  ;

at which NRC notification is required by PBNP [

1. Technical Specification. requirements. If a measured level of radioactivity in any on-- '

vironmental medium exceeds the regulatory notification level listed in Table 2-2, re-  !

sampling and/or reanalysis for confirmation  ;

shall be completed within 30 days of the  :

detemination of the anomalous result. If the confimed measured level of radioactivity '

remains above the notification level, a written report shall be submitted to the NRC. -j If more than one of the radionuclides listed. '

in Table 2-2 are detected in any environs ntal medium, a weighted sua calculation shall be -e performed if the measured concentration of a {

detected radionuclide is greater than 25% of the notification levels. For those radio-nuclides with LLDs in excess of 25% of the ,

notification level, a weighted sua calcula-tion need be performed only if the reported -

value exceeds the LLD. Radionuclide concen- t tration levels, called Weighted Sun &ction  ;

Levels, which trigger a weighted sua calcu-  ;

lation are listed in Table 2-2.  !

written report shall be submitted to the NRC.

This calculation requirement and report is not * '

required if the measured level of redioactivity was not the restCt of plant effluents.

2.2.4.2 Administrati10 Notification Levels -

The NPERS administrative NLs are the concen-tration levels at which the contracted analyti-  ;

cal laboratory promptly notifies the cognizant ,

NPERS engineer by phone, followed by a fonnal  ;

, written communication. The NPERS a hinistrative  ;

.( NLs are set lower than the NRC regulatory NLs and lower than, or equal to,'the weighted ,

sua action levels so that the nature and origin of the increased level of environ-mental radioactivity may be expeditious 1f .

ascertained and corrective actions.taken if  !

required. l 2.2.5 Sampling Locations  ;

& list of sampling locations and the corresponding ,

location codes appear in Table 2-3. The locations also are shown in Figures 2-la and 2-lb. It is conceivable ,

that samples may become unavailable from specified sample -

locations. If this were to occur, new locations for 1 obtaining replacement samples shall be identified and added l

to the Radiological Environmental Nonitoring Program. If  ;

milk or vegetation samples become unavailable from the specified saspling locations, new sampling locations ,

will be identified within 30 days. The specific locations '

where samples were unavailable may be deleted from the monitoring program. A formal, written reason for the new site and its location shall be transmitted to the cognizant NPERS Engineer who will make the appropriate

- changes to the Environmental Nanual. Any significant ,

for the change shall be reported in the semiannual Monitoring Report for the period in which the change occurred. Additional sampling locations may be desig-nated if deemed necessary by cognizant Company personnel.

2.2.6 sampling Media and Frequency The sampling Anquency for the environmental media required by PI@ Technical specifications is found in Table 2-4. In addition to samples required by technical

." specifications, the Radiological Environmental Moni-toring Program also includes the sampling of soil and shoreline sediment. To ensure that all samples are obtained at the appropriate times, two different checklists are used. A yearly checklist provides a month-by-month indication of all samples, encept air, to be obtained at each sampling location (Figure 2-2). .

This checklist also identifies the schedule for the annual milk survey and provides space for recording the date the samples were shipped offsite for analysis. In addition, a separate checklist is provided for each sampling location to identify all samples, including weekly air samples, to be obtained and the collection f ( _. date (Figure 2-3). Because the weekly air samples

\ require additional information, a separate checklist is used for each individual air sampling location as shown in Figure 2-4.

It is recognized that on occasions samples will be lost or that samples cannot be collected at the specified frequency because of hasardous conditions, seasonable unavailability, automatic sampling equipment malfunctions, and other legitimate reasons. Reasonable efforts will-be made to recover lost or missed samples if warranted and appropriate. The reasons or explanations for deviations from the sampling frequency specified in Table 2-4 shall be logged at PENP an$ shall be conveyed formally in writing to the cognizant NPERS Engineer using the appropriate form (Figure 2-6). A description of the reasons for not conducting the saipling as specified and, when appropriate, plans for preventing ti recurrence shall be identified in the next Semiennual Monitoring Report by tia "ognizant NPERS Enginear.

2.2.9 Sample analy,ses and Frequency The P8NP Radiological Environmental Monitoring Program samples shall be analyzed for designated parameters at the frequency listed in Table 2-5.

2.2.10 Analytical Laboratory The analyses are performed by a contractor. The current contractor is Teledyne Isotopes Midwest Laboratory 700 Landwehr Road Northbrook, IL 60062-4517 (708) 564-0700.

This laboratory, formerly named Hazleton Environmental Sciences Corporation, perfot1ms i.h5 mrlyges in such a manner as to attain the desired LLDs. The contracted laboratory participates in the interlaboratory comparison-crosscheck program conducted by the U.S. Environmental Protection Agency, Intercomparison and Calibration Section, Quality assurance Branch, Environmental Moni-toring and Support Laboratory, Las Vegas, Nevada.

The contractor is responsible for providing prompt notification to NPERS regarding any 6,mples fmd to exceed the NPERS administrative notification levels es identified in Table 2-2.

2.3 Assistance to the State of Wisconsin As a courtesy and convenience, PRNP personnel obtain certain environmental samples for the Section of Radiation Protection, Department of Health and Social Services of the State of Wisconsin as listed in Table 2-6. A checklist is used as shown in Figure 2-3. In addition, a State of Wisconsin air sampling data sheet is submitted with each sample obtained at Wisconsin air sampling locations serviced by PBNP personnel.

Use a scissors or other sharp cutting tool to cut the grasses and weeds off as close to the ground as possible. Do not include plant roots and take care not to contaminate the sample with soil. Total sample collected should exceed 500 grams and ideally should be 1000 grams. l Place entire sample in a plastic bag, tape the bag shut, and label the bag as described in Section 2.2.7.

2.4.5 Air

(' 2.4.5.1 Sample collection Air filters are changed weekly at specified locations. Take precautions to avoid loss of collected material and to avoid contamination when handling filters. Washing hands before leaving the plant to change filters is a recommended practice.

Both particulate filters and charcoal cartridges

. are employed at each saspling location.

Particulate filters are analysed for gross  !

beta activity after waiting for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to allow for the decay of short-lived radon and thoron daughter products. The contractor makes quarterly composites of the weekly particulate samples for gamma isotopic analyses.

A regulated pump (Eberline Model RAS-1 or equivalent) is used at each air sampling location. Because of the automatic flow regulation, rotameter readings at the beginning and ending of the sampling period should be

-( nearly identical. Substantial differences in readings usually require some investigation 2-11

to determine the cause. The rotameters l attached to the. pumps are calibrated in liters i per minute. When new filters are installed,. I flow rate should be about 28-30 lys. Flow )

rates less than 26 1pm or greater than 32 1pm i require that the pump regulator be readjusted. i The correct flow rate is detemined by multi-plying the rotemeter reading by the correction factor indicated on the calibration sticker afflued to the rotameter, j The pumps are equipped with an elapsed time meter which reads in hours._ Elapsed time in j hours for the sample is obtained by subtracting  !

EBnr19000BNT&L MMRIAL Revision 7 March 1990 2.4.5.2 Air Sampling System Description

'The air monitoring equipment for the P8HP air sampling program consists of a regulated rate control system. The regulated rate control system is used at PaNP because of its simplicity and reliability. It is designed to minimise both calibration difficulties and the potential for leaks. The regulated rate control. system includes a pump,- a flow regulator, an electrical hour meter, the appropriate filter holders and a minimum of tubing. In this system, the total volume sampled can be calculated slaply and accurately from the elapsed time indicated on the hour meter and the. flow rate which is kept constant by the regulator regardless of filter loading.

The air samplers are Eberline b oel R&S-1 (or equivalent) and have built in totameters which read in liters per minute. The systems also include a 1000-hr elapsed time meter, an Eberline WPH-1 (or equivalent) weatherproof

{ housing, and an iodine cartridge holder and mounting kit. Currently, all metallic and rigid plastic tubing and rigid fittings are used in lieu of tygon tubing and quick dis-con-nects. Glass fiber, 47 an diameter, particulate-filters capable of collecting 95% of 1 micron diameter particles and iodine tapregnated char-coal cartridges (Scott or equivalent) constitute the filter media.

2.4.5.3 Calibration .

Calibrate the pump rotameter at initial installa-tion and at yearly intervals thereafter by con-necting a laboratory-quality reference flow meter with NBS traceable calibration to the filter face with the particulate filter and charcoal cartridge

, in position. Upon completion, a calibration sticker indicating the correction factor is affixed to, or near, the built-in rotameter. The results are recorded on the form shown in Figure 2-7.

.k:-

2.4.5.4 Inspection and Maintenance

. Initially, and M quarterly intervals, not to escoed 16 weeks, thereafter, the assembled system should be checked for leaks by attaching the reference flow meter across the face of the filter holder with the filters in position. ~ Leakage in this configuration is-indicated by'a higher read-ing on the built-in rotameter than on the refer-ence flow meter. Because leakage is-indicaced by; disagreement between the two flow measuring de-vices, remember to apply the calibration.correc-tion factor to the built-in rotameter reading.-

Leak tests are to be recorded on the form shown in Figure 2-7.

For normal operation, the regulators should be -

adjusted to maintain a true flow rate of 28-30 liters per minute. Adjustments are made by turning the screw marked FLOW ADJUST. located on the side of the regulator body: counterclx k-wise increases flow, clockwise decreases flow. Flow rates should be observed at all

. (- filter changes. Flow rates less than 26 3pm

\ or more than 321pm require readjustment of the regulator. Particular attentiota should be paid to flow rate readings with the,"old",

loaded filter and with new, unused filters in position. Because of the regulator, the difference in flow should be barely perceptible, perhaps no more than one lpa. Significant differences in flow rates require further investigation to determine the cause.

Preventive maintenance shall be performed on all environmental air samplers and the results recorded on the form shown in Figure 2-7.

2.4.5.5 Pump Repair and Replacement The pumps can operate for long periods of time with minimal or no maintenance. The vane assembly of the pump is most susceptible to failure, indicated by excessive noise or inability to maintain sufficient flow across loaded filters. At least one standby pump should be available for temporary service 2-15 k

y March 1990 f; r i

i during the repair period. In the event of i motor failures due to causes other than '

defective connections, complete replacement of the unit may be necessary. All pump repairs should be done in a clean-side shop with clean tools.

2.4.6 Milk Because of iodine decay and protein binding of iodine  ;

in aging milk samples, speed is imperative in processing and samples must be kept cool to avoid degradation and spoilage of the samples. Milk samples are obtained monthly in conjunction with the state of Wisconsin milk sampling program from three-  !

individual dairy farmers located ndrth; south, and west .!

-of the site. Because two of the three sites are ,

co-located, the PBNP pickup is coordinated to coincide i with the state arranged schedule. .The pickup'usually will be the first Wednesday of the month. j l- The following sequence should be followed:

( a. After verifying the State milk pickup date with

\ the Manitowoc Public Health Department (Mr.

• Alan Troullier, phone number'683-4454) notify ,

Mr. Leon Strutz (755-2060) of the pickup date.

This must be done because the strutz farm (PBNP-sampling location E-21) is not a State of Wisconsin sampling site. -

p. Because the milk must be kept cool, but not I frozen, fill enough cubitainers with water and L

freeze to be able to put one in each shipping container. Fill the cubitainers with water '

and freeze the day preceding the pickup.

c. The milk from the Strutz farm (E-21) must be picked up before 0900 because that is the time '

the-Strutz milk is shipped. A late arrival ,

may mean a missed sample. Milk from sites  !

E-11 and E-19 may be picked up any time after the Strutz pickup.

d. Identify yourself and the nature of your '

business at each milk pickup site. collect  ;

two one-gallon samples from each site, using a '

funnel if necessary. Place each gallon in a '

one-gallon box liner for shipment. If l shipment cannot occur on the collection day, i store the milk in a clean-side refrigerator overnight. DO NOT FREEZE. t

e. Complete a PSNP sample tag according to Section 2.2.7 for each gallon sasple and place in the box with the sample. Do not seal the box. Place the samples in insulated containers (found on the Ready Stores  :

receiving dock) and.take them to Ready Stores. ,

Make sure that the cover letter and, as appropriate, the contractor data collection sheets are sent according to Section 2.2.8 of this manual. .

{

2.4.7 Algae i Filamentous algae are collected from pilings or rocks three times per year, as available, from two locations. .

The long, grassy, dark green algae can nomally be cut

( vith scissors. The shorter, light green algae

\ normally must be scraped from rocks or pilings. When ,

scraping algae, be careful not to include pieces of -

rock in the sample. The sample can be lightly rinsed in the same medium in which it is growing. -This  ;

rinse will help rid the sample of pieces of rock and r gravel that may have been inadvertently collected ,

with the sample. Because rocks and sediment contain naturally occurring radioactive materials, their '

inclusion may give false sample resulte. Collect between 100 and 1000 p of' algae. A sample greater l than 500 p is preferred. Place the algae in a 1000 al cubitainer and label the container as directed in Section 2.2.7. The algae must be kept cool to prevent spoilage.

2.4.8 Fish Fish are obtained three times per year (March, August, and December) as available either from the traveling ,

screens as washed into the fish basket or by other methods as required. For any given sampling period, three fish or a sufficient number to yield at least 1000 gm of fillets should be provided.

2-17 ,

ENVIRCISEENyE MDRIAL Ravision 7 March 1990

(' .

Place fish in plastic bags and tape and/or tie tightly closed. Fish are stored briefly in a radiologically clean freezer. It may be desirable in wam weather to coordinate milk and fish saspling, thereby allowing simultaneous shipment in insulated containers. Pack ffsh samples with ice if needed. Label bags as directed in section 2.2.7, being sure to indicate fish species when possible. Following packaging of fish, remove and discard any fish left in the freezer. This avoids sending fish that are not representative of the sampling period.

V

< , Fish are obtained four times per year (March, June, September, and December) for the state of Wisconsin.

Fish sampling performed for the state is performed in the same manner as that for the plant. Approximately four fish should be sent to the state at each sampling .

period.

In March and December split samples are sent to Teledyne and the State of Wisconsin. Each fish is

-birected with one half going to Teledyne and.the other half-to-the state.

2.4.9 soil.

Soil integrates atmospheric deposition and acts as a reservoir for long-lived radionuclides. Although soil sampling is a poor technique for assessing small incre-mental releases and for monitoring routine releases,-it does provide a means of monitoring long-tem trends in atmospheric deposition in the vicinity of PBNP. There-fore soil samples are obtained two times per year from-specified locations.

~

Clear the vegetation from a 6a x 6" area, being careful to leave the top layer of soil relatively intact. Remove root bound soil by shaking the soil onto the cleared area or into the sample container before discarding the roots. When necessary, it is preferable to leave some roots in the soil rather than to lose the top layer of soil.

Remove the soil to a depth of 3 inches. If necessary, expand the area, instead of digging deeper, to obtain the required amount of sample. If an area larger than 6"m6" is used, notify the cognizant NPERS Engineer of the area used. The minimum acceptable quantity is 500 grams. Place the entire soil sample

(_. in a 1000 ml plastic bag and seal the bag with tape.

Label the sample as directed in Section 2.2.7.

monitoring is a conservative measure undertaken to determine whether the operation of the Point Beach Nuclear Plant produces any significant radio-l? logical change in the surrounding environment.
