NUCLEAR POWER BUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 1.0 RADIOL.OGICAL ENVIRONMENTAL MONITORING PROGRAM ADMINISTRATION l 1.1 Definition and Basis i l 1.1.1 Definition Radiological environmental monitoring is the measurement of radioactivity in samples collected from the atmospheric, aquatic and terrestrial environment around the Point Beach Nuclear Plant (PBNP), Monitoring radioactivity in ellluent streams at or prior to the point of discharge to the environment is not i l part of the Radiological Environmental Monitoring Program (REMP).

1.1.2 Basis The REMP is part of the PBNP Radiological Emuent and Materials Control and Accountability Program (REMCAP). The REMP is designed to fulfill the requirements of 10 CFR 20.1302, PBNP GDC 17, GDC 64 of Appendix A to 10 CFR 50, and Sections IV.B.2 and IV.B.3 of Appendix I to 10 CFR 50.

No significant radionuclide concentrations of plant origin are expected in the plant environs because radioactivity in plant effluent is continuously monitored to ensure that releases are well below levels which are considered safe upper limits. The REMP is conducted to demonstrate compliance with applicable standards, to assess the radiological environmental impact of PUNP operations, and to monitor the efficacy ofinplant efiluent controls. The REMP, as outlined in Tables 2-2 through 2 5 is designed to provide sufficient sample types and locations to detect and to evaluate changes in environmental radioactivity. ,

Radioactivity is released in liquid and gaseous effluents. Air samplers and thermoluminescent dosimeters placed at various locations provide means of detecting changes in environmental radioactivity as a result of plant releases to the atmosphere. Because the land area around PBNP is used primarily for farming and dairy operations, sampling of vegetation is conducted to detect changes in radiological conditions at the base of the food chain. Sampling of area produced milk is conducted because dairy farming is a major industry in the area.

ENVIRONMENTAL h1ANUAL h!AJOR Revision 12 DRAFT l ENVIRONh1 ENTAL MANUAL- December 1.1997 Water, periphyton, and fish are analyzed to monitor radionuclide levels in  :

Lake hilchigan in the vicinity of PBNP. Periphyton, attached algae, along with lake water samples, provide a means of detecting changes which may  :

have a potential impact on the radionuclide concentrations in Lake hiichigan  :

fish. Because of the migratory behavior of fish, fish sampling is of minimal >

value for determining radiological impact specifically related to the operation -

of the Point Beach Nuclear Plant. Howes er, fish sampling is carried out as a conservative measure with emphasis on species which are ofintermediate i

trophic level and which exhibit minimal migration in order to monitor the

~

status of radioactivity in tish.

Vegetation, algae, anu fish sampling frequencies are qualified on an "as 1 available" basis recognizing that certain biological samples may occasionally be unavailable due to environmental conditions.

1.2 Resnonsibilities for Procram Imnlementation 4

l 1.2.1 Radiological Engineering Functions Radiological Engineering (RE) together with Licensing provides the PBNP -

manager with the technical, regulatory, licensing, and administrative support necessary for the implementation of the program. The RE administrative functions relating to the REhtP fall into the six broad areas outlined below,

a. Program scope .

The scope of the REh1P is determined by Radiological Engineering based on sound radiological principles for the fulfillment of PBNP Technical Specifications (TS) and the applicable Federal Regulations. Based on the scope, the Environmental hianual (Eht) is written to accomplish the collection and analyses of the necessary environmental samples. The Eh! .

is revised as necessary to conform to changes in procedures and scope.

Radiological Engineering monitors the REh!P effectiveness and compliance with TS and with the procedures and directives in the Eht. In order to verify compliance with TS, Radiological Engineering or Quality Assurance arranges for program audits and audits of the contracted radioanalyticallaboratory. ,

b. Record keeping 4

The monthly radioanalytical results from the contracted laboratory are reviewed by the cognizant Radiological engineer and two copies of the report are forwarded to PBNP. One copy of the monthly radioanalytical results from the contracted laboratory is kept for the lifetime of the plant at PBNP.

c. Data monitoring l The cognizant Radiological Engineer (RE) reviews and interprets all program analytical results on a monthly basis as they are reported. Trends, if any, are noted. Any resulting corrections, mod 10 cations and additions to the data are made by the cognizant RE. Inconsistencies are investigated by the cognizant RE with the cooperation of PBNP and contractor personnel, as required. Unusual results as evidenced by radioactivity levels exceeding administrative notincation levels are also investigated.

Results of the investigation will be conveyed to the Manager - PBNP. The congnizant RE will promptly inform PBNP of any sample exceeding Nuclear R gulatory Commission (NRC) regulatory notincation levels and will initiate an investigation. A formal report shall be provided to th:

Manager PBNP upon completion of the investigation.

d. Data summary Results from the Radiological Environmental Monitoring Program shall he summarized annually for inclusion in the PBNP Annual Monitoring Report. This summary advises the Manager - PBNP of the radiological status of the environment in the vicinity of PBNP. The summary shall include the numbers and types of samples as well as the averages, statistical con 0dence limits and the ranges of analytical results. Methods used in summarizing data are at the discretion of Radiological Engineering.

NUCLEAR POWER BUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 1.3 - Ouality Assurance /Ouality Control Quality assurance considerations are an integral part of Wisconsin Electric's Radiological Environmental Monitoring Program. The program involves the interaction of l Radiological Engineering, Point Beach Nuclear Plant (PBNP), Wisconsin Electric's Quality Assurance Section (QAS) and Teledyne Brown Engineering Environmental Services (THEES).

The TBEES quality assurance and quality control program is described in the TBEES Quality Assurance Program Manual and the TBEES Quality Control Procedures Manual.

Copies of these ma als may be reviewed by Radiological Engineering and QAS personnel prior to audits. The laboratory is audited periodically, either by Wisconsin Electric or by an independent third party. When an independent third party is used, the audit is accepted after a satisfactory review of the audit report by the Wisconsin Electric QAS. If Wisconsin Electric performs the audit, the quality assurance portion of the audit is performed by QAS and the technical portion is performed by Radiological Engineering, with assistance from PBNP llP as appropriate. As part ofits quality control program, TBEES participates in an environmental crosscheck program.

Quality control for the PBNP portion of the Rediological Environmental Monitoring Program is achieved by following the procedures contained in this manual. Ilealth Physics technologists (liPTs) collect, package and ship environmental samples under the l supervision ofIlealth Physics supervisors. They are advised by the Specialist - Nuclear llcalth 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 these procedures.

An audit of the PBNP Radiological Environmental Monitoring Program and its results j shall be completed periodically as a means of monitoring program effectiveness and assuring compliance with program directives. The audit shall be performed by either IRSS personnel, QAS or a qualified consuh.ag finn, h

2.1 Procram Overview 4

2.1.1 Purpose No significant or unexpected radionuclide concentrations of plant origin are i expected because each normal efnuent pathway at PDNP is monitored at or  ;

before the release point. Ilowever, the Radiological Enyhonmental l Monitoring Program is conducted to verify that plant operations produce no signincant radiological impact on the environment and to demonstrate  ;

compliance with applicable standards.  ;

2.1.2 Samples  !

Samples for the Radiological Environmental Monitoring Program are obtained - ,

from the aquatic, terrestrial and atmospheric environment. The sample types represent key indicators or critical pathways identified by applying sound radiological principles to the PONP em itonment.

2.1.3 Monitoring sensitivity The etTectiveness of the Radiological Environmental Monitoring Program in ful0lling its purpose depends upon the ability to accurately determine the nature and origins of Ductuations in low levels of enviromnental radioactivity.

This requires a high 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.

2.2 hggram Parameters l l

2.2.1 Contamination avoidance j Contamination prevents the accurate quantification of environmental  !

radioactivity and the correct differentiation between fluctuating background  ;

radioactivity and levels of radioactivity attributable to the operation of PBNP. l Therefore, it is necessary that all personnel associated with collecting and handling radiological environmental samples take the appropriate precautions  !

to minimize the possibility of contaminating the samples. 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 conjunction with radiological environruental monitoring;
b. Store sampling equipment in radiologically clean areas only;
c. Store radiological environmental sampics only in radiologically clean areas when samples cannot 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. contamination;
c. Radiological environmental monitoring equipment should be repaired in clean side shops;
f. ontamination avoidance for environmental TLDs is covered in

>ection 2.4.2; and

g. Do not enter the controlled zone prior to leaving to collect environmental samples.

2.2.2 Sample size Sample size affects the sensitivity achievable in quantifying low levels of environmental radioactivity. Therefore, sampling personnel must attempt to attain the quantities of sample specified in Table 2-1 When a range is given, every effort should be made to obtain a quantity at the upper part of the range.

ENVIRONMENTAL MANUAL December 1,1997 2.2.3 Lower limit ofdetection 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 i smallest concentration of radioactive material in a sample that uill yield a net ,

count, above system background, that will be detected with a 95% probability and have only a 5% probebility of falsely concluding that a blank observation represents a real signal, Mathematically, the LLD is defined by the formu:  ;

66 S.

LLD =

E x V x 2.22 x Y x EXP(4.AT)

Where LLD = the a priori lower limit of detection in picoeuries per unit volume or mass, as applicable; Sb

= the standard deviation of the background counting rate or the counting rate of a blank sample, as appropriate, in counts per minutes; E = counting efficiency in coun's per disintegration; i

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 applicable; A = the radioactive decay constant for the particularradionuclide; and AT = the elapsed time between sample collection, or the end of the collection period, and the time of counting.

Page11.of38

l NUCLEAR POWER HUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 Typical values of E. V, Y, and AT are used to calculate the LLD. As defined, the LLD is an a enori lir.Jt representing the capability of a measuring system i and not an a nosteriori limit for a particular measurement.

The required analysis fbr each environmental sample and the highest acceptable LLD associated with each analysis are listed in Table 2 2.

Whenever LLD values lower than those specified in Table 2 2 are reasonably achievable, the analytical contractor for the radiological environmental samples will do so. When the LLDs listed in Table 2 2 are not achieved, a '

description of the factors contributing to the higher LLD shall be reported in j the next PBNP Annual Manitoring Report.

2.2 A - Noti 0 cation lesels  ;

The Notification Level (NL) is that measured quantity of radioactivity in an environmental sample which, when exceeded, requires a notification of such an occurrence be made to the appryriate party, Regulatory and aununistrative notification levels are listed in Table 2 2,

a. Regulatory not10 cation levels l The regulatory noti 0 cation levels listed in Table 2-2 represent the concentration levels at which NRC nonfication is required. If a measured level of radioactivity in any radiological environmental monitoring program sample exceeds the regulatory notification level listed in Table 2 2, resampling and/or reanalysis for confirmation shall be completed within 30 days of the determination of the anomalous result. If the confirmed measured level of radioactivity remains above the notification level, a written report shall be submitted to the NRC. If more <

than one of the radionuclides listed in Table 2-2 are detected in any environmental medium, h weighted sum calculation shall be performed if the measured concentration of a detected radionuclide is greater than 25%

of the noti 0 cation levels. For those radionuclides with LLDs in excess of 25% of the notiFeation level, a weighted sum calculation needs to be performed only if the reported value exceeds the LLD. Radionuclide concentration levels, called Weighted Sum Action Levels, which trigger a weighted sum calculation are listed in Table 2-2.

b. Administrative notification levels l The administrative notification levels are the concentration levels at which the contracted analytical laboratory promptly notifies the cognizant Radiological Engineer by phone, followed by a formal written communication. The administrative notification levels are set lower than '

the NRC regulatory notification levels and lower than, or equal to, the weighted sum action levels so that the nature and origin of the increased level of environmental radioactivity may be expeditiously ascertained and corrective actions taken if required. ,

2.2.5 Sampling locations A list of sampling locations and the corresponding location codes appear in Table 24. The locations also are shown in Figures 2-1 A and 21B, it is conceivable that samples may become unavailable from specified sample

-locations. If this were to occur, n:w locations for obtaining replacement samples shall be identified and added to the Radiological Environmental hlonitoring Program. If milk or vegetation samples become unavailable from the specified sampling 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 fonnal, written reason for the new site and its location shall be transmitted to the cognizant Radiological Engineer who will make the appropriate changes to the Environmental  !

hianual. Any significant changes in existing sampling location and the -

l criteria for the change shall be reported in the Annual htonitoring Report for ,

the period in which the change occurred. Additional sampling locations may be designated if deemed neccessary by cognizant company personnel. Figures

. and tables in this manual shall be revised to reflect the changes.

2.2.6 Sampling media and frequency l The sampling frequency for the environmental media required by the PBNP REMP is found in Table 2 4. In addition to samples required by the former Technical Specifications, the Radiological Environmental Monitoring 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, except air, to be obtained at each sampling location (PDF 4121).

This checklist also identifies the schedule for the annual milk survey and .

pravides 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 date (PDF 4075 series). Because the weekly air samples l require additional information, a separate checklist is used for each individual air sampling location as shown in PDF 4078.

It is recognized that on occasions samples will be lost or that samples cannot be collected at the spedfied frequency because of hazardous 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. If samples are not obtained at the indicated frequency or location, the reasons or explanations for deviations from the sampling frequency specified in Table 2 4 shall be logged at PBNP and shall be conveyed fonnally in writing to the cognizant Radiological Engineer using the appropriate form (Figure 2 2). The cognizant engineer will evaluate the sampling problem to determine whether it constitutes a reportable l deviation from the requirements in Table 2-4. Ifit does, a description of the reasons for not conducting the sampling as specified and, when appropriate, plans for preventing a recurrence, shall be identified in the next Annual Monitoring Report by the cognizant Radiological Engineer.

2.2.7 Sample labeling All samples must be properly labeled to ensure that the necessary information  ;

is conveyed to the analytical contractor and that the results are associated with ,

the correct geographical location. Each label (PBF-4026) must contain the following:

a. Sample type;

- b. Sample location from Table 2-3;

c. Date and time (as appropriate) collected; Page 14 of 38

ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL DecerrSer 1,1997 2.3 Assistance to the State of Wisconsin As a courtesy and convenience, PBNP 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 PDF-4075 series, 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.

State of Wisconsin precipitation samples collected twice a month (or as available) require a state sample tag to be placed in a box with the quart cubitainer. State supplied labels fer air particulate filteis require start and stop time, date and beginning and ending volume. Fish sent to the state identify only the quarter and the year using a PBNP label (PDF 4026). The monthly lake water composite is picked up by state personnel and

'Wfore requires only that the date and location be written on the box for the cubitainer.

The state provides a sample tag for the quarterly lake water sample.

Samples obtained for the State of Wisconsin are either given directly to state personnel or shipped as required. The department address is:

Radiation Protection Laboratory Room 111 State Laboratory ofliygiene 465 llenry Mall Madison, Wisconsin 53706 2.4 Specification of Samnline Procedures General radiological environmental sampling procedures follow the directives presented in Sections 2.1 and 2.2. Specific information for handling individual sample types follow.

2.4.1 Vegetation Vegetation samples consist of green, growing grasses and weeds and are obtained three times per year, as available, from specified locations. New growth, not dead vegetation, should be used because these samples are indicators of recent atmospheric deposition. Use a scissors or other sharp-cutting tool to c_ut the grasses and weeds ofTas 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. Plaec entire sample in an appropriate container, such as a plastic bag (tape the bag shut) and label the container as described in Section 2.2.7 Page 17 of 38

NUCLEAR POWER BUSINESS UNIT EM-ENVIRONMENTAL MANUAL MAJOR 1 Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 2.4.2 Thennoluminescent dosimeters (TLDs)

TLDs capable of multiple, independent measurements of the same exposure are posted at the tw enty seven (27) locations specified in Table 2-4 and are changed quarterly. The utmost care in handling is required to minimize '

unnecenary exposure during transit, storage and posting because the TLDs begin recording all radiation from the moment they are annealed (heated to rezero) at the contractor's laboratory. Packages of TLDs in transit should be marked "Do NOT X RAY."

A transportation control (E TC) shall accompany the new batch in transit from the contractor's laboratory to the plant. The control shall accompany the batch

  • during brief storage and subsequent posting. The sms control shall accompany the "old" or exposed batch on its way back to the contractor.

Therefore, each control represents the sum of approximately half the in transit exposure of the two batches. This control system is able to identify any unusualin transit exposure.

Environmental TLDs should never be brought into the plant controlled zone or any other area with elevated radiation, but may be stored for brief periods in a shielded enclosure in the Extension L3uilding or other low background area, such as the basement of the Energy Center or the Site Boundary Control Center. The contractor is to time shipments to coincide as closely as possible with the beginning of a calendar quartet TLDs should be shipped back to the contract! r immediately or within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of removal. The contractor is instructed to process the amples immediately upon receipt. The contractor

. shall report removal data and cumulative readings in mR for all locations and control, correct for in transit exposure and express results in net mR/7 days, i Labels of the exposed set for shipment to contractor should show both posting and removal dates.

2.4.3 Lake water Lake water samples are obtained monthly at specified locations. As a special case, the water sample at the discharge flurne is composited weekly for monthly analysis. The contractor is responsible for the compositing for quanerly analyses. Collect approximately 8000 ml oflake water in the l required number of cubitainers, or other appropriate containers, at each location and label as directed in Section 2.2.7.

Lake water is collected at the request of the state of Wisconsin, These ramples are collected, labeled, and forwarded to '.he appropriate agency.

ENVIRONMENTAL MANUAL December 1,1997 2.4.4 Well water Well water samples are obtained quarterly from the single onsite well. Collect approximately 8000 ml of well water using the required number of cubitainers l or other appropriate containers. Label as directed in Section 2.2.7. ,

2.4.5 Air

, a. 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 eac5 sampling location. Particulate filters are analyzed 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 uimposites 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 to determine the cause. The rotameters attached to the pumps are calibrated in liters per minute. When new filters are installed, ,

flow rate should be about 28-301pm. Flow rates less than 261pm or greater than 32 Ipm require that the pump regulator be readjusted. The correct flow rate is determined by multiplying the rotameter reading by the correction factor indicated on the calibration sticker affixed to the rotameter.

Some pumps are equipped with an elapsed time meter which reads in hours. Form PDF-4078 is used for recording pertinent air sampling data for each location. At a normal filter change, the following procedure will apply:

1. Record "date off" and " time off"
2. Record rotameter reading for end of period (R2)-

' Page 19 of 38  ;

i

NUCLEAR l'OWER BUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 ,

3. Turn off pump, if ne:eseary, and record hour meter reading or actual time for end of period (13).
4. Before removing the filter, label the envelope as directed in Section 2.2.7. Also enter any other pertinent information at this  :

time. Always write data on the envelope before the particulate filter  ;

is in the envelope.

i

5. Remove particulate filter being careful to handle filter only by edges, place in envelope.
6. Remove charcoal cadridge, place in plastic bag, and laael as directed in Section 2.2.7.
7. Install new charcoal cartridge and particulate filter being sure to check the charcoal cartridge for breaks and the particulate filter for holes in the filter surface. Discard unacceptable filter inedia.
8. Record "date on."
9. Record hour meter reading or time for beginning of period (ti ).
10. Tum pump on (if necessary).

I 1. Perform weekly gross leak test by blocking the air flow with a large rubber stopper. (For this test only, the rotameter ball may register zero or drop all the way to the bottom. The difference between zero and the bottom is not significant.)

12. Record rotameter reading for beginning of period (R i).
13. Record correction factor as indicated on calibration sticker affixed to totameter (C).
14. Observe that the starting rotameter reading (Ri )is close to the previous ending reading (R2 ). A substantial difference indicates need for further 4- t'!gmon because the regulator will generally maintain constani n n. tegardless of filter loading.

NUCLEAR POWER BUSINESS UNIT EM l ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 l 3

15. Calculate total volume for period and enter on data sheet (m ). (This step may be performed at a later time.)
16. Any unusual conditions or observations should be referenced under

(*) and recorded under " NOTES" at the bottom of the data sheet.

Air samples are collected for the State of Wisconsin at three locations, on: of which is co-located with a PBNP air sampling site.

They are handled in a manner similar to Pi>NP samples except that no charcoal cartridges are involved. However, state samplers are equipped with volume integrating meters. Therefore, clock time mus* be recorded in addition to the ending and beginning volumes.

Label and forward samples to the State.

b. Air sampling system description The air monitoring equipment for the PBNP air sampling program consists of a Regulated Rate Control System. The Regulated Rate Control System is used at PBNP because ofits simplicity and reliability, it is designed to minimize both calibration difficulties and the potential for leaks. The regulated rate control system includes a pump, a flow regulator, the appropriate filter holders and a minimum of tubing. Also, it may include an ela; ad time meter. In this system, the total volume sampled can be calculated simply and accurately from the elapsed time and the flow rate which is kept constant by the regulator regardless of filter loading.

The air samplers are Eberline Model RAS-1 (or equivalent) and have built-in rotameters which read in liters per minute. The systems also include an Eberline WPH-1 (or equivalent) weatherproof housing and an iodine cartridge holder and mounting kit and may include an electric hour meter, Currently, all metallic and rigid plastic tubing and rigid fittings are used in lieu of tygon tubing and quick disconnects. Glass fiber,47 mm diameter, particulate filters capable of collecting 95% of 1 micron diameter particles and iodine impregnated charcoal cartridges (Scott or equivalent) constitute the filter media.

c. Calibration Calibrate the pump rotameter at initial installation and at yearly intervals thereafter by connecting 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 Form PBF-4020.

di Inspection and maintenance

, initially, and at quarterly intervals, not to exceed 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. t Leakage in this configuration is indicated by a higher reading on the

+ built in rotameter than on the reference flow meter. Because leakage is indicated by disagreement between the two flow measuring devices, remember to apply the calibration correction factor to the built in-rotameter reading. Leak tests are to be recorded on_ Form PDF-4020.-

Weekly gross leak checks and quarterly leak tests shall be accomplished as indicated in the appropriate PBNP procedure.  :

For normal operation, the regulators should be adjusted to maintain a true flow rate of 28 30 liters per minute. Adjustments are made by tuming the i screw marked FLOW ADJUST located on the side of the regulator body:

counterclockwise increases flow, clockwise decreases flow. Flow rates should be observed at all filter changes. Flow rates less than 261pm or e more than 321pm require readjustment of the regulator Particular attention 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 Ipm. Significant differences in flow rates require further investigation to 4 determine the cause.

Preventive maintenance shall be performed as indicated in the appropriate  ;

PBNP procedure on all environmental air samplers and the results recorded on Form PDF-4020.

c. 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 enessive noise or inability to maintain sufficient flow across loaded filters. At least one standby pump should be available for

temporary service during the repair period. In the event of 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; 4

NUCLEAR POWER BUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 2.4.6 Milk Because ofiodine decay and protein binding ofiodine in eging 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 Sampiing Program from three individual dairy farmers located north, south, and west of the site. Because two of the three sites are co-located, the PBNP pickup is coordinated to coincide with the State arranged schedule. The pickup usually will be the first Wednesday of~ a month.

The following sequence should be followed:

a. After verifying the State milk pickup date with the Manitowoc Public Health Depanment (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 samp! ins site.
b. Because the milk must be kept cool, but not frozen,611 enough cubitainers, or other appropriate containers, with water and freeze to be able to put one in each shipping container. Fill the containers 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.

l Collect two one gallon samples from each site, using a funnel if necessary.

If shipment cannot occur on the collection day, store the milk in a clean-side refrigerator overnight. DO NOT FREEZE.

e. Complete a PBNP sample tag according to Section 2.2.7 for each gallon sample and place in the box with the sample. Do not seal the box. Place the samples in insulated containers and turn them over to Ready Stores personnel for shipment. 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.

NUCLEAR POWER BUSINESS UNIT EM ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 2.4.7 Algae Filamentous algae are collected from pilings or rocks three times per year, as available, from two locations. The long, grassy, dark green algae can normally be cut with 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 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 results. Collect between 100 and 1000 gm of algae. A sample greater than 500 gm is preferred. Place the algae

-l in a wide-mouth poly bottle or other appropriate container and label the container as director 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.

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 warm weather to coordinate milk and fish sampling, thereby allowing simultaneous shipment in insulated containers. Pack fish 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.

Fish are obtained four times per year (March, June, September and December) for the State of Wisconsin. Fish sampling for the State is performed in the same manner as that for the plant. Approximately fnur fish should be sent to the state at each sampling period.

NUCLEAR POWER BUSINESS UNIT EM

- ENVIRONMENTAL MANUAL MAJOR Revision 12 DRAFT ENVIRONMENTAL MANUAL December 1,1997 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 incremental releases and for monitoring routine releases, it does provide a means of monitoring long-term trends in atmospheric deposition in the vicinity of PBNP. Therefore, soil samples are obtained two times per year from specified locations.

Clear the vegetation from a 6" 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 three inches. If necessary, expand the area, instead of digging deeper, to obtain the required amount of sample. If an area l larger than 6" x 6" is used, notify the cognizant Radiological Engineer of the area used. The minimum acceptable quantity is 500 grams. Place the entire soil sample in a wide-mouth poly bottle or another appropriate container. If a plastic bag is used, seal the bag with tape. Label the sample as directed in Section 2.2.7.

This procedure assumes that the samples are obtained from undisturbed land; land that has not been plowed within apprcximately the last 25 years. If the land has been plowed, the soil should be sampled to the plow depth which typically is eight inches. Place the soil in a clean bucket or appropriate size plastic bag, homogenize the soil and place 1000 grams of the well mixed soil -

l sample in a plastic bag, or other appropriate container, and label as described above.

2.4.10 Shoreline Sediment Shoreline sediment consisting of sand and smaller grain size material is sampled two times per year from specified locations. The 1000 gram sample is collected, from beach areas near the water ridge. At each location collect representative samples of sediment types roughly in proportion to their occurrence. For example, at E-06 avoid collecting a sample which consists exclusively of the dark-brown to black sediments which occur in layers up to several inches thick. Package the sample in a wide-mouth poly bottle or other appropriate container and label as described in Section 2.2.7.

The veri 6 cation is conducted each summer by cognizant PBNP personnel. Because it is already assumed that milk animals may graze up to the site boundary, it is only necessary to verify that these animals have not moved onto the site. No animal census is required.

Upon completion of the visual check, PBNP personnel will notify IRSS in writing. To ensure performance of the annual veri 6 cation, " milk review" is identi6ed on the sampling checklist, PBF-4121.
