PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT I.

INTRODUCTION The 1997 Palisades Nuclear Plant Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Radiological Environmental Monitoring Program, as conducted during the 1997 reporting period. Reporting requirements are detailed in Palisades Offsite Dose Calculation Manual (ODCM), Appendix A, sections 111.J and IV.B, Tables E-1 through E-3, and Table F-1.

Detailed sample station identification and location information can be found in of Health Physics Procedure HP 10.10 (Enclosure C). The

.. results of all environmental samples collected are evaluated as follows:

A.

Air iodine and particulate and thermoluminescent dosimetry (TLDs)

(monthly, quarterly and annual) data were statistically evaluated at the 95% confidence level by the methodology detailed in Health Physics Procedure HP 10.4. The data were compared against two criteria: the first criterion is the statistical difference which indicates whether the sample results from near sites are greater than those from control sites, and whether or not the difference is significant. The second criterion is the evaluation level (twice the statistical difference) which is the minimum difference in the population means for which a corresponding difference in sample means will exceed the statistical difference with 95% confidence.

If the evaluation level is exceeded, then correlation of the results with effluent releases is complete.

B.

Well water, lake water, sediment, fish and other aquatic biota samples were evaluated using data means comparisons against an appropriate control location (if available) and Palisades ODCM, Appendix A, limits.

II.

. REPORTABLE EVENTS No reportable events occurred during this reporting period.

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Ill.

DISCUSSION AND INTERPRETATION OF RESULTS A.

Air Sample A total of 624 air samples were collected and analyzed for gross beta and 1-131 during 1997. All samples collected were included in the data analysis and all met Palisades Offsite Dose Calculation Manual (ODCM),

Appendix A, sensitivity requirements.

Comparison of the airborne particulate sample data between the nine near-site indicator locations, and the three control locations did not exceed the statistical difference. In most instances, control location sample values were greater than indicator location samples. The means of gross beta results for indicator and control locations were 0.023 pCi/m3 and 0.024 pCi/m3, respedively. No sample analyses identified 1-131 activity above minimum detectable levels.

Air iodine/particulate samples are collected on a weekly basis from twelve air sampling locations. Air is metered into the sampling unit at a continuous one cubic foot per minute flow rate (approximately) through a Gelman 47mm air filter (air particulate) and a Hl-Q air iodine cartridge.

Both filters are in-line with each other and housed within the same filter holder.

B.

Lake Water A total of 36 individual monthly lake water composite samples were collected from three locations during 1997. Lake water samples from the indicator locations, Palisades Lake-in (1-ST Intake), and South Haven Municipal Water system intake (25-SH Raw water), and the control location Ludington Lake-in (32-LP Intake}, were collected daily.

Evaluation of the monthly lake water analytical results was based on a data mean comparison between the indicator locations and control location. The results were also evaluated against the Palisades ODCM, Appendix A, reporting limits.

Gross beta analyses were completed for all lake water samples. The means for gross beta indicators and controls were 2.5 pCi/L and 3.0 pCi/L, respectively. Tritium was detected in several indicator and control samples. The means for tritium indicator and controls were 179 pCi/L and 220 pCi/L, respectively. No Palisades ODCM reporting limits were exceeded.

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Although the lake-out (discharge) sample is not used as an indicator in the

  • Radiological Environmental Monitoring Program, it is monitored for activity. Monthly gross alpha and tritium results from the Palisades Lake-

. in sample and the Ludington Plant Intake control sample were used for comparison data against the Lake-out (discharge) sample results. Gross alpha was detected in several Lake-out and Lake-in samples at slightly above minimum detectable activity levels. Several lake-out tritium results were positive. On three occasions during 1997 the tritium activity for the discharge was above the ODCM action level of 1000 pCi/L. These

~levated levels were all correlated to liquid effluent discharges and were confirmed by comparison to calculated effluent tritium concentrations.

Palisades Lake-in, South Haven Municipal and Ludington Lake-in water*

samples are collected daily for composite into a monthly sample. One gallon of Palisades Lake-in water, one gallon of Ludington Lake-in water, and two gallons of South Haven Municipal water are sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with preservative is required.

C.

. Drinking Water A total of 36 individual monthly drinking water samples were collected*

  • from three locations in 1997. Lake water samples from the indicator locations, South Haven Municipal Water System (25-SH Raw Water, 25-SH Treated) and the control location, Ludington lake-in (32-LP Intake),

were collected daily and composited into monthly samples.

Evaluation of the drinking water analytical results was based on a data means comparison between the indicator locations and the control location, as well as a comparison to the Pali~ades ODCM reporting limits.

Both of the South Haven Municipal lake water intake and treated drinking water samples require gross beta analyses. A tritium analysis is required for the treated water only. The gross beta means for the indicator and control locations were 2.3 pCi/L and 3.0 pCi/L, respectively. Tritium was detected in several indicator and control samples. The means for tritium indicator and controls were 215 pCi/L and 220 pCi/L, respectively. No

  • special or supplemental analyses were required during 1997.

. ~outh Haven Municipal and Ludington Lake-in water samples are collected daily for composite into a monthly sample. One-gallon of Ludington Lake-in water, and two gallons of South Haven Municipal water are sent to Teledyne Brown Engineering for analysis. No treatment of the

.water samples with preservative is required.

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT D.

Well Water A total of 108 monthly well water samples were collected from nine locations during 1997. Evaluation of the well water analytical results was based on a data means comparison between the six indicator locations (1-ST, 39-ST, 40-ST, 41-ST, 42-ST and 43-ST) and the three control locations (8-SP, 9-TP, and 32-LP) as well as with the Palisades ODCM reporting limits.

Tritium and gross beta analyses were completed for all well water samples. The gross beta means for indicator and control locations were 4.2 pCi/L and 1.8 pCi/L, respectively. The tritium means for indicator and control locations were 168 pCi/L and 172 pCi/L, respectively.

No Palisades ODCM reporting limits were exceeded for the 1997 well water samples. Evaluation of the gross beta activity between indicator and control locations revealed a statistical difference. However, in a comparison between wells used for Palisades plant drinking water (1-ST, 40-ST) versus the three control samples, the gross beta results were very consistent at 1.4 pCi/L and 1.8 pCi/L respectively. The Steam Generator and Warehouse monitoring wells had a gross beta average of 5.6 pCi/L for 1997, which caused the statistical difference between indicator and control stations.

In 1997, one well sample exceeded the gross beta ODCM action level of 10 pCi/L. This occurred at site# 14 (41-ST) in February, with results at 10.4 pCi/L. The gamma analysis of this sample indicated the presence of K-40 (naturally occurring) and supported the conclusion that this elevated gross beta result was not the result of plant effluents. The Steam Generator and Warehouse wells typically trend around 4 to 8 pCi/L gross beta and it is not unusual for results to exceed the 10 pCi/L action level during the winter months. Refer to Enclosure A for all sample collection anomaly evaluations.

The Palisades site well (1-ST) location is collected daily and composited into a monthly sample. The other eight well locations consist of monthly grab samples.

Well water samples consisting of two one-gallon quantities for each well are sent to Teledyne Brown Engineering for analysis (Ludington control station consists of a one-gallon sample). No treatment of the water samples with a preservative is necessary.

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT E.

Milk A total of 48 individual monthly milk samples were collected from four different dairy farms (stations 26-AK, 27-KK, 28-DC and 29-WS) during 1997. The milk samples are obtained as grab samples (from dairy milk holding tanks). During late December of 1996 the Crnkovich Farm (7.5 mi NE) sold their remaining dairy herd. Beginning in January 1997 the Allen Karr Farm (5.75 mi ESE) was selected as the replacement milk station.

No milk analysis identified activity above the minimum detectable level.

No special or supplemental analyses were required, nor were any Palisades ODCM reporting limits exceeded.

Milk samples are required monthly (usually collected the first week of the month) from each designated location. Two one-gallon quantities of raw milk (grab sample) are obtained per sample location in order to meet analytical requirements. Each sample quantity is treated with a sodium bisulfite (40 grams per gallon ) preservative prior to being sent to Teledyne Brown Engineering for analysis.

F.

TLDs - Gamma Dose There were a total of 347 monthly, 116 quarterly and 29 annual TLDs collected and analyzed during 1997. One Monthly TLD was missing in 1997. Refer to enclosure A for all sample collection anomaly evaluations.

The Palisades gamma assessment program consists of 29 locations:

one directly on-site, nine near site and six Steam Generator Storage Facility TLDs for a total of sixteen inner ring TLDs, ten outer ring (1.0 to 5.5 miles out) and three control TLDs (30 to 55 miles out). A thirtieth TLD is placed in a lead storage cave and used as a control for in-transit dose monitoring and subtraction.

The monthly and quarterly TLD data evaluations were accomplished by statistically comparing the inner ring TLDs (site boundary locations 1-ST, 13-21 ST and 33-38 ST) and the outer ring TLDs (locations 2-TH through 9-TP, 23-SN25 and 24-SN22) against the control TLD locations (10-GR, 11-KZ, and 12-DG). The annual TLD data evaluation was done by direct comparison of data points only. No monthly or quarterly statistical differences were exceeded.

.5

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT For 1997, the average gamma readings (mR) were:

Inner ring TLDs (site boundary)

Outer ring TLDs (1.0 to 5.5 miles out)

Control TLD locations Monthly 3.6 4.2 4.3 Quarterly 11.3

.12.8 13.0 Annual.

42.6 48.8 49.3 The one on-site TLD location (1-ST) serves as an individual reference.

TLD, however it was evaluated along with the inner ring (site boundary)

TLDs in the statistical evaluation.

In evaluating the inner ring TLDs to the control TLDs, control station 11-KZ (35 mi. SSE) had the greatest monthly, quarterly, and annual mean of 4.9 mR, 14.6 mR, and 54.6 mR respectively.

When the same comparison was made for the outer ring TLDs, 2-TH (Tower Hill, 5 mi. S) had the greatest monthly, quarterly and annual mean for any location of 5.0 mR, 16.0 mR, and 58.4 mR respectively..

Environmental gamma doses are measured monthly, quarterly and annually by placement of three TLD badges per designated location.

Each Teledyne TLD badge contains a 4-zone CaS04 wafer (the wafer includes an additional backup/reserve readout zone). Sensitivity for the multi-zone TLDs are 1.0 millirem with a linear response of 0.1 millirem to 1000 rem.

G.

Crops During 1997, 15 crop samples were collected from two stations (4-JS, and 5-PR). Evaluation of sample analytical results was direct. There was no control location used.

Of the radionuclide analyses listed on Table HP 10.4-2, only gross beta

' analysis resulted in any detectable activity. The gross beta mean for the indicator locations was 1.73 pCi/g. The crop samples at station 4-JS had the greatest individual mean for gross beta activity of 1.78 pCi/g. No Palisades ODCM action or reporting levels were exceeded, nor were any special/supplemental analyses required during 1997.

Food crop samples were collected when available and in season. Two principal area crops, apples and blueberries, are regularly collected as specified in the ODCM. While there are no designated locations where food crops are collected, samples are generally obtained from the sa~e 6

v PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT areas where the air monitoring stations are located within the ESE, SE or SSE sectors. The collection of food crops assists in verifying stack effluent deposition patterns. When collected, approximately 1 Kg of sample is placed in a sealable plastic bag for shipment to Teledyne Brown Engineering. No special treatment of the samples with a preservative is necessary.

. H.

Sediment A total of 10 individual sediment samples were collected from five locations during 1997. Eight sediment samples were obtained from Palisades (1-ST discharge, 31-STS % mi South of discharge, 30-STN %

mi North of discharge and 25-SH South Haven Beach) locations and two samples from the Ludington Control Station (32-LP).

Evaluation of the sediment analytical results was based on a data means comparison between Palisades and the Ludington control samples as well as the Palisades ODCM, Appendix A, reporting limits. Of the radionuclide analyses listed on Table HP 10.4-2, only gross beta, and Cs-137 activity were detectable. The gross beta means for indicator and control locations were 5.96 pCi/g and 8.22 pCi/g, respectively. The Cs-137 means for indicator and control stations were 0.020 pCi/g and 0.023 pCi/g respectively. Location 32-LP (Ludington Control) had the greatest mean for gross beta and Cs-137. No Palisades ODCM action or reporting levels were exceeded, nor were any special or supplemental analyses required during 1997.

Sediment samples are collected semi-annually from each designated location. A one liter quantity grab sample usually is obtained off-shore.

No treatment of the samples with a preservative is necessary prior to shipment to Teledyne Brown Engineering.

I.

Aquatic Biota - Algae The Palisades Radiological Environmental Monitoring Program does not require algae to be collected, although it is collected when it is available.

Two algae samples were collected in 1997 from the Palisades discharge (1-ST) indicator location, however, none were obtained (not available in 1997) from the Ludington Plant (32-LP) control location.

The 1997 indicator analytical results were slightly higher than 1996, but lower than 1994 and 1995 indicator activities. The mean gross beta for 7

y PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 1-ST location was 2.39 pCi/g, in comparison to 1996 results of 1.0 pCi/g, and 1994 and 1995 gross beta results of 3.3 pCi/g, and 4.3 pCi/g respectively. Cs-137 and other gamma emitters were not detected in 1997, and were not detected in 1996.

One liter quantities of algae (when available) are prepared for shipment to Teledyne Brown Engineering by treating each sample with 10 ml of a 10%

formaldehyde solution for preservation.

J.

Fish A total of 11 individual fish samples were collected from two locations during 1997. Seven indicator samples were obtained from Palisades (1-ST discharge) and four control samples were obtained from the Ludington Station (32-LP). Evaluation of the fish analytical results was based on a data meal"1s comparison between the Palisades and Ludington Control Samples as well as with the Palisades ODCM reporting limits. The gross beta means for indicator and control locations were 1.78 pCi/g and 1.85 pCi/g, respectively. Cs-137 was detected in one of the seven indicator samples, and in two of the four control samples. The Cs-137 mean for indicator and control location was 0.048 pCi/g and 0.025 pCi/g respectively. Comparison of results between similar species ( salmonids and suckers) at the different locations resulted in no significant differences. No Palisades ODCM action levels or reporting levels were exceeded, nor were any* special analyses requested for 1997.

Fish samples are collected semi-annually. If possible, at least two different fish species (i.e., forage, sport fish, etc.) are sampled semi-annually at designated sample locations. When caught, a one liter quantity of fish sample is prepared for shipment to Teledyne Brown Engineering. Each sample is treated with a 10% formaldehyde solution for preservation.

K.

Broad Leaf Vegetation No broad leaf vegetation samples were collected from the surrounding Palisades environs during 1997. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling media in case any milk sampling location(s) become(s) unavailable. There were no problems associated with the quantity or quality of milk samples for the 1997 reporting year.

PALISADES NUCLEAR PLANT 1997 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT L.

Non-Routine Samples No non-routine samples were collected during this reporting period.

M.

Gaseous and Liquid Radwaste Effluent Composite Samples Although not a direct reporting component in the Palisades Annual Radiological Environmental Operating report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. This evaluation is the basis for

  • determining isotopic dispersion and deposition patterns within the surrounding environs of Palisades. All gaseous and liquid effluent results are compared to Palisades ODCM, Appendix A, reporting levels. All isotopic LLDs were met.

Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Teledyne Brown Engineering for analysis.

No special sample treatment with a preserva~ive is required prior to laboratory analysis. The liquid effluent composite sample is based on a specific amount of samples collected per total batch volume release. As noted in Enclosure A, for months in which there were no liquid batch effluent releases, no sample is sent to Teledyne Brown Engineering. The gaseous radwaste effluent weekly composite sample results are based on analyzing weekly stack gas filters.

IV.

ASSESSMENT OF PALISADES OPERATION ENVIRONMENTAL IMPACT In reviewing the 1997 Palisades radiological environmental monitoring data and.

comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of Palisades has minimal environmental impact. Most isotopic activity is at environmental background levels. Evidence of an overall environmental isotopic buildup (attributable to Plant effluents) remains negligible as well. In most instances, sample analytical results were below previously established environment background levels.

Delay in shipment (2)

Activity not due to Plant effluents, suspect road de-icer as contaminant. (3}

There were no liquid effluent batch releases during these time periods. Consequently No sample is collected and sent to Teledyne Isotopes.

(1)

In April the TLD collection holder at station 10-GR could not be located. Suspect that the holder blew off its mount during an earlier wind storm. The quarterly and annual spares were place into service on May 1. The April monthly TLD data is lost. To prevent recurrence, the new style TLD holder (with end caps) was placed into service at this station, and secured to the mounting bracket.

(2)

The Ba-La-140 LLD at the Palisades 1-ST for fish and the Ludington control station was not met due to the delay in shipment of these samples to the Lab. The Consumer Energy stockroom misplaced the samples, which resulted in a 90 day delay in shipment.

To prevent recurrence all fish and Biota samples collected at Palisades and Ludington will be shipped by the local Teledyne collector at Palisades, or shipped via UPS to the Laboratory within seven days of collection by the RETSIREMP analyst.

(3)

Follow up analysis (gamma spectroscopy) showed all isotopes (except K-40) less than LLD. Activity is not due to Plant effluents, suspect road de-icer as contaminant, as higher activity at this well site is only seen in winter months, and sample locations are near road run-offs and Plant parking areas.

.REMP File DCC: 950/72*10*03/LP The attached tables and map are the results of the Palisades Land Use Census conducted by MLGrogan and SCSunday on July 30, 1997. Table 10.11-1 references the distance from Palisades to the nearest residence, garden (greater than 500 square feet), beef/dairy cattle, and goat per meteorological sector. Table 10.11-2 identifies the locations of the nearest residence and garden; and of all beef/dairy cattle and goats within a five (5) mile radius of Palisades per meteorological sector. Table 10.11-3 lists the critical receptor locations used in calculation of the offsite doses by the GASPAR computer program. An accompanying map illustrates Table 10.11-2. Prior to conducting the land use census tl:le Van Buren County.Agricultural Extension Office.

was contacted as required by Procequre HP 10.11.

The only change to critical receptor locations (from the 1996 Land Use Survey) is the Garden, which changed from the NE sector (1.2 miles), to the SE sector (1.0 miles).

However, all X/Q (sec/m3) values increased slightly with the use of the Palisades 1992-1996 composite meteorological d~ta.

Tables 10.11-1 and 10.11-3 are required to be updated in the ODCM as Tables 1.4 and 1.4a respectively.* Attached to th's report are the new revisions of Tables 1.4 and 1.4a.
