Big Rock Point Nuclear Plant Annual Radiological Environmental Operating Report January through December 2004
Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 I. Introduction The 2004 Big Rock Point Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Big Rock Point Radiological Environmental Monitoring Program (REMP) as conducted during the 2004 reporting period. Reporting requirements are detailed in the Big Rock Point Defueled Technical Specifications 6.7.2, and Offsite Dose Calculation Manual (ODCM) Section 1II, Subsection 2.0.
Big Rock Point's Defueled Technical Specifications no longer contain requirements for the REMP; rather, this program is now contained in the Big Rock Point ODCM Section 1I1.The radiological environmental monitoring sampling requirements are greatly reduced when compared to the plant's operating period. A land use census is no longer required for Big Rock Point.
Use of an assumed garden and milk animal at the site boundary in the downwind sector of highest D/Q, per ODCM Section II, Table 1.4, is conservative with respect to any actual garden and milk locations.
During 2004 decommissioning activities resulted in permanent dismantlement and removal of the designated gaseous and liquid effluent locations, also known as the off-gas stack and discharge canal, respectively. Tables 1, 2 and 3 provide a summary of 2004 BRP REMP sample requirements and results.
Detailed sample station identification and location information can be found in Enclosure B. Well water, lake water intake/discharge, sediment, and fish samples were evaluated using data means comparisons against an appropriate control location (if available) and BRP ODCM limits. There are no remaining 2004 laboratory sample analyses pending completion for inclusion into this report.
The BRP ISFSI dry fuel storage facility environmental monitoring requirements pursuant to 10 CFR Part 72.44(d)(3) were submitted to the NRC in a letter dated February 25, 2005.

Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 Discussion and Interpretation of Results A. TLDs - Gamma Dose The Big Rock Point gamma dose assessment program consists of 13 TLD locations: four on-site TLDs (locations 1-ST, 14-G, 15-H, and 17-K), six site boundary TLDs (locations 9-A, 10-B, 11-C, 12-D, 13-F, 16-J), and three control TLDs, 10.5 to 50 miles out, (locations 5-PT, 6-BC, 7-TR).
Environmental gamma doses are measured quarterly and annually by placement of two TLD badges per designated location. Enclosure B provides a description and diagrams for TLD locations.
For 2004 the average quarterly gamma readings were:
24.8 millirem for the onsite TLDs; 11.3 millirem for the site boundary TLDs, and 12.1 millirem for the control TLD locations.
The average of the annual gamma readings in 2004 were:
115.0 millirem for the onsite TLDs, 50.7 millirem for the site boundary TLDs, and 51.7 millirem for the control TLD locations.
The onsite quarterly TLD mean and the onsite annual TLD measured in 2004 are slightly less than that of 2003; this is most likely due to continued removal of source term contributors resulting from offsite disposal of decommissioned plant equipment and structures. Site boundary and offsite control TLDs are consistent with 2003 Annual Radiological Environmental Operating Report and historical data.
A statistical evaluation was completed comparing 2004 offsite control TLD data to site boundary TLD data. The site boundary TLD mean, although lower than the offsite control mean, is not statistically different than the offsite control TLD mean.
Each TLD badge contains a 4-zone CaSO 4 phosphor wafer (the wafer also includes an additional backup/reserve read-out zone). Sensitivity for the multi-zone TLDs are 1.0 millirem with a linear response to 1000 rem.
B. Air Samples The Big Rock Point Radiological Environmental Monitoring Program no longer requires airborne surveillance be conducted.
C. Milk 2
Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 C. Milk The Big Rock Point Radiological Environmental Monitoring Program no longer requires milk samples be collected.
D. Lake Water The Big Rock Point Lake water inlet sample is required for monthly tritium and gamma isotopic analysis (gross beta is no longer required). For Lake inlet samples in 2004 neither tritium nor gamma isotopes were detected in any of the plant inlet samples. Since there was one liquid batch release completed in January, the only monthly composite sample was collected during January 2004.
Plant discharge water samples also were collected, although they are not required. Plant discharge samples are analyzed for tritium, Sr-89 and Sr-
- 90. None of the plant or control location water samples detected Sr-89 or Sr-90.
BRP lake inlet and Ludington lake inlet samples are collected daily for composite into a monthly sample. A one-gallon quantity of sample is sent to Environmental Inc. Midwest Laboratory for analysis. No treatment of the water samples with a preservative is necessary.
E. Well Water The BRP ODCM requires semiannual sampling of the site drinking water well with analysis for tritium and gamma isotopes. Well water samples were collected in June and December. None of the analyses detected any tritium or gamma isotopes in the well water samples.
Evaluation of the well water analytical results was based on a data comparison between the BRP site well and the Ludington well samples.
Ludington well water control samples are analyzed for tritium only. No indicator or control well water samples had any detectable tritium. No BRP ODCM reporting limits were exceeded nor were any special/supplemental analyses required during 2004.
F. Groundwater Monitoring Wells Big Rock Point ODCM requires semiannual sampling of six site groundwater monitoring wells, with analysis for tritium and gamma isotopes. Big Rock Point has up to 22 monitoring wells available for sampling. Nine of the groundwater monitoring wells were originally installed in 1994 while the majority of monitoring wells were installed in 2002 and 2003 for the purpose of additional groundwater characterization. All available wells are sampled 3
Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 on a quarterly basis; however, decommissioning activities may temporarily or permanently render some of the monitoring wells unavailable for sampling.
A total of sixty monitoring well samples were collected and analyzed. All gamma isotopic results were less than detectable. Tritium was detected above the required LLD in 27 of the samples at a mean of 1167 pCi/L.
Historically MW-5 and MW-6 typically have shown the highest detectable tritium concentrations. The mean value for MW-5 and MW-6 is 3176 pCi/L, slightly lower than the 2003 mean value of 4130 pCi/L for the same well locations. Enclosure E contains a chart depicting the overall trend for MW-5 and MW-6 since plant shutdown in 1997. All monitoring well samples collected in 2004 were below the reporting criteria of 20,000 pCi/L.
Ludington well water control samples are analyzed for tritium only; none of these samples yielded detectable tritium concentrations.
Each well water sample consists of a one-gallon grab sample. This sample is sent to Environmental Inc. Midwest Laboratory for analysis. No treatment of the water samples with a preservative is necessary.
G. Drinking Water Collection of drinking water samples, other than the plant's drinking water supply well (see Section E), is no longer required by the BRP Radiological Environmental Monitoring Program.
H. Crops The collection of food crops/vegetation samples is not required by the BRP Radiological Environmental Monitoring Program.
I. Sediment A total of four individual sediment samples were collected from four locations during 2004. Sediment samples locations are the BRP discharge channel (1-ST), 1/4 mile south of discharge (24-STS), 1/4 mile north of discharge (25-STN), and the Ludington control station (26-LP, 115 miles SSW).
Evaluation of the sediment analytical results was based on data mean comparisons between the BRP samples and the Ludington control samples and the BRP ODCM reporting limits. Gross beta was detected in all four samples; mean values for the indicator and control sarmples were 10.5 pCi/g and 9.1 pCi/L, respectively. Cs-137 was detected in three indicator samples with a mean of 0.30 pCi/g. Co-60 was detected in three indicator samples with a mean of 0.37 pCi/g. Detection of Cs-1 37 and Co-60 were at levels slightly higher than the 2003 values for these sample locations. Neither Cs-4
Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 137 nor Co-60 were detected in control samples. The sediment gross beta and gamma activity results are presented in graphical form in Enclosure E for 1997-2004.
No BRP ODCM reporting levels or action levels were exceeded during 2004.
Semi-annual sediment samples were not collected in the fall of 2004 due to permanent decommissioning and restoration of the discharge canal.
Sediment sampling has resumed in 2005 for available locations along the shoreline.
Sediment samples are collected in one-liter quantities and obtained a few yards off-shore. No treatment of the samples with a preservative is necessary prior to shipment to Environmental Inc. Midwest Laboratory.
J. Fish The BRP Radiological Environmental Monitoring Program requires that either one fish or invertebrate (crayfish) sample is collected semi-annually at or near the Plant discharge area. One fish sample was collected from the plant discharge area (1-ST discharge) in June 2004; a semi-annual fish sample was not collected in the fall of 2004 due to permanent decommissioning and restoration of the discharge canal. Control samples were taken from the Ludington location. Radionuclide analyses results are listed in Table 2 for these samples. The spring fish sample from the plant discharge location (1-ST) indicated the presence of Cs-1 37 at less than one-half of the required LLD. Gross beta, which originates primarily from naturally-occurring background radionuclides, is not required by the Big Rock Point ODCM for fish samples.
No BRP ODCM reporting levels were exceeded nor were any special or supplemental analyses required during 2004.
One liter quantities of frozen fish are sent to Environmental Inc. Midwest Laboratory for analysis.
K. Crayfish No crayfish samples were collected in 2004.
L. Aquatic Biota The collection/analysis of aquatic biota (algae and periphyton) is no longer required for the Big Rock Point Radiological Environmental Monitoring Program.

Big Rock Point Annual Radiological Environmental Operating Report January to December 2004 M. Broad Leaf Vegetation The collection/analysis of broad leaf vegetation is no longer required in the Big Rock Point Radiological Environmental Monitoring Program.
N. Gaseous and Liquid Radwaste Effluent Composite Samples Although not a direct reporting component in the BRP Annual Radiological Environmental Monitoring Report, results of collected gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. All isotopic analysis results were below BRP ODCM reporting levels.
Gaseous effluent composite samples were collected monthly and sent to Environmental Inc. Midwest Laboratory for analysis. The gaseous effluent monthly composite sample results are based on analyzing four or five weekly effluent filters. The liquid effluent composite sample is based on a specific volume amount of sample collected per total batch volume released.
As noted in Enclosure C, only one liquid effluent composite sample corresponding to the single batch release for 2004 was sent to Environmental Inc. Midwest Laboratory. No special sample treatment with a preservative is required prior to laboratory analysis.
Ill. Assessment of Big Rock Point's Operational Environmental Impact In reviewing the 2004 Big Rock Point radiological environmental monitoring data and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that operation and decommissioning activities of Big Rock Point have minimal environmental impact. Most radionuclide activity is at environmental "background" levels. Evidence of an overall environmental isotopic build-up (attributable to Plant effluent) remains negligible at all locations other than the plant discharge canal (sample location ST-1). In most instances, sample analytical results were below previously established environmental background levels. A comparison of analytical results showed that the plant discharge canal, formerly the licensed radioactive liquid release point, remained the indicator location with the highest annual mean for the samples collected in spring 2004. The discharge canal was fully remediated and the shoreline restored to its original contour in the fall of 2004.

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.
January through December, 2004
Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.
The results in Table A-2 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.
Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request. request.
Table A-5 list results of the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.
Attachment A lists acceptance criteria for "spiked" samples.
Out-of-limit results are explained directly below the result.

d MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP.
d The cause of the deviation seems to be incomplete dissolution of the sample.
e A spiked soil sample was prepared. Known activity; 32.98 pCi/g; laboratory result 33.47 pCi/g.
The sample was reanalyzed with the same results. Investigation is in progress.
9 Based on the results of gamma emitting isotopes (Cs-137 and Co-60), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results in a recalculation of 2.12 +/- 0.15 Bq/sample.

APPENDIX B DATA REPORTING CONVENTIONS B-1
Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.
2.0. Single Measurements Each single measurement is reported as follows: x s$
where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.
3.0. Duplicate analyses 3.1 Individual results: For two analysis results; xi +/- sl and X2 +/- s2 Reported result: x s; where x= (112) (xI + x2) and s = (1/2) s +s2 3.2. Individual results: <L 1 , <L2 Renorted result: <L, where L = lower of LI and L2 3.3. Individual results: x +/- s, <L Regorted result: x +/- s if x 2L; <L otherwise.
4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x1 , x2 . .. xn are defined as follows:
x 2 x- x =X-4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.
4.5 In rounding off, the following rules are followed:
4.5.1. If the number following those to be retained is less than 5, the number is dropped, and the retained number s are kept unchanged. As an example, 11.443 is rounded off to 11.44.
4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.
