SUMMARY

This report contains results from the operational Radiological Environmental Monitoring Program (REMP) for Diablo Canyon Power Plant (DCPP) compiled for the period January 1, 2004, through December 31, 2004. This program is conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RPI1.D1)1, "Environmental Radiological Monitoring Procedure."

The results of the 2004 REMP showed no unusual findings from plant operations, and that the operation of DCPP had no significant radiological impact on the environment. Plant operations had no significant impact on airborne radioactivity in the environment. The ambient direct radiation levels in the DCPP environs did not change and were within the preoperational range. No plant related radionuclides were detected in surface water samples except that tritium was detected in one water sample collected at the plant discharge. The plant had no significant impact on surface water. Food crops sampled during their growing season and milk samples collected detected only naturally occurring radioactivity; and therefore, there was no impact from plant operation. Five marine samples contained other than naturally occurring radionuclides. Cobalt-58 was detected in two algae samples collected from Diablo Cove. The cobalt-58 detected in these algae samples was slightly above detection levels. In addition, zinc-65 was detected in one kelp sample collected from Diablo Cove. Low concentrations of various plant related radionuclides have been detected in algae collected from Diablo Cove several times in the operational period.

However, the detected radionuclide concentrations have been random and near the lower limits of detection. Therefore, there is no increasing trend of plant related radionuclides in algae collected from Diablo Cove. Zinc-65 was also detected in a mussel sample collected from Diablo Cove. Zinc-65 has not been previously identified in mussel samples from Diablo Cove, but it is not unexpected since mussels are known to concentrate zinc and the plant has released more of this isotope since the introduction of stable zinc as a corrosion inhibitor to the reactor coolant system several years ago. One sample of fish obtained from a local fish market contained a small concentration of cesium-137. This isotope in a comparable concentration is routinely measured in fish collected worldwide due to fallout of this long lived isotope from past nuclear weapons tests in the atmosphere.

Section 1 INTRODUCTION Diablo Canyon Power Plant (DCPP) consists of two Westinghouse pressurized water reactors. Unit 1 began commercial operation in 1985, and Unit 2 began commercial operation in 1986. This report contains results from the operational Radiological Environmental Monitoring Program (REMP) for DCPP compiled for the period January 1, 2004, through December 31, 2004. This program was designed to identify and quantify ambient radioactivity concentrations in the DCPP environs and to determine whether there were any significant increases in the concentration of radionuclides, attributable to plant operations, in the critical dose pathways from the environment to man. Also included in this report are the results of PG&E's Technical and Ecological Services (TES) participation in an external lab cross check program, a discussion of the TES results compared with the results from the State of California Department of Health Services (DHS) Sanitation and Radiation Laboratory (SRL) of the same or duplicate samples, and the current land use census of the plant environs conducted by plant personnel.

DCPP ENVIRONMENTAL MONITORING PROGRAM The REMP was conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RPl.ID1 1, "Environmental Radiological Monitoring Procedure."

The environmental media selected were based on the critical dose pathways of the radionuclides from the environment to man. They included the following: direct radiation, air, water, fish, and invertebrates.

Supplemental samples such as algae, local agricultural crops, and milk were also collected. The collection frequency of the samples from the different media is summarized in Table 1. The samples were collected by PG&E's DCPP personnel.

The sampling locations were determined by land use, site meteorology, and local demographics. The distances and directions to the environmental monitoring stations are listed in Table 2. The off-site and on-site stations are shown in Figures 1 and 2, respectively.

Section 2 SAMPLING METHODS This section summarizes briefly the various sampling methods.

AIRBORNE RADIOACTIVITY Air particulate and radioiodine sampling were performed weekly at six indicator stations: MT1, 0S2, IS 1, 7D1, 8S1 and 8S2, and at one control station 5F1.

Constant flow air samplers were used to draw air through paper filters to collect air particulates and through triethylenediamine (TEDA) impregnated charcoal cartridges to collect radioiodine. The air samplers were set at a flow rate of 1.5 cubic foot per minute and were located one meter above the ground.

Sample volumes were determined using flow rate and timer values through May 12"'. After that time the sample volumes were determined by gas meters which are installed downstream of the sample head.

On the week starting February 18fe, the iodine cartridge type used in the air sampling train was changed to the RADECO RL-100. The newer style of cartridge provides positive indication of air flow through the cartridge, and the manufacturer provides better documentation on the cartridge's iodine collection efficiency than the previous manufacture.

At the end of the sampling period, the filter and cartridge were collected. All necessary data regarding the air volume readings on and off, run time, sampler time on and off, date of collection, and sampler location were recorded and submitted, along with the samples, to TES for analysis.

DIRECT RADIATION Direct radiation was measured at 31 stations in the vicinity of DCPP using Panasonic UD8 14 TLD badges.

These badges were replaced on a quarterly basis.

The field TLD badge packets were prepared by DCPP personnel. Control badges were carried with the field badges to measure any dose received during transit. The location, date, and time of exchange were recorded on the log sheet which accompanied the field badges.

WATER SAMPLES Water samples (drinking water and surface water) were collected monthly. Two 1-gallon plastic bottles of each water sample type were collected at their respective locations each month.

Surface water samples were collected at Diablo Cove (station DCM), Rattlesnake Canyon (station 7C2),

and at the plant outfall. Drinking water samples were collected from Diablo Creek Weir (station 5S2) 420DC-05.19.doc 2-1

located on-site and from the drinking water system at DCPP. After collection, the samples were securely sealed and labeled with sample type, location, date, time of collection, and the person performing the collection and sent to TES for analysis.

MARINE BIOLOGICAL AND SEDIMENT SAMPLES The REMP requires only one sample of rockfish (Sebastes sp.), one sample of perch (family Embiotocidae), and one sample of mussels (mytilus) from indicator station DCM and control station 7C2.

All other marine samples collected are considered supplemental. These supplemental marine samples included, but were not limited to, the following: intertidal algae, kelp, and market fish. The intertidal samples (algae and mussels) were collected quarterly during low tidal conditions. Kelp was collected quarterly from the offshore kelp bed in the vicinity of the plant. Quarterly samples of fish and an annual sample of ocean bottom sediment were collected from the plant environs by divers. Fish caught locally and purchased from the fish market were also analyzed. All samples were subject to unavailability due to seasonal fluctuations or unfavorable sampling conditions.

The samples were sealed in plastic bags immediately upon collection and labeled with sample type, location, date, time of collection, and individual performing the collection before they were sent to TES.

FOOD CROPS The REMP requires broadleaf vegetation to be collected in the nearest off-site locations of the highest calculated annual average ground level D/Q (dispersion parameter). There is no broadleaf vegetation available that satisfies this requirement. However, representative samples of food crops in season were collected monthly from supplemental stations: Cal Poly Farm (station 5F2), Kawaoka Farm in Arroyo Grande (station 7GI), Mello Farm (station 7C1) along the site access road, and quarterly at a household garden (station 6CI). The samples were collected, sealed immediately in plastic bags, labeled with sample type, sample location, collection date, time of collection, and the individual performing the collection, and sent to TES for analysis.

MILK There are no milking animals in the vicinity of the plant. However, supplemental samples of milk were collected monthly from Cal Poly Farm (station 5F2). Two I-gallon plastic bottles of milk were collected each sampling period. Forty grams of sodium bisulfite preservative were added to each gallon of milk sample. The bottles were sealed and shaken thoroughly to distribute the preservative. They were labeled with sample type, sample location, date and time of collection, and the individual performing the collection, and sent to TES for analysis.

420DC-05.19.doc 2-2

Section 3 SAMPLE ANALYSES Samples received at TES were analyzed for radioactivity by standard methods as outlined in TES Work Instructions. The results of the analyses were reported at the 95 percent confidence level. All analyses were performed such that the lower limits of detection (LLDs), listed on Table 3, were achieved under routine conditions. The LLD is an a priori (before the fact) estimate of the activity concentration that can be practically achievable with a given measuring instrument, procedure, and type of sample. This value is not intended to be used as an a posteriori (after the fact) criterion for the presence of activity.

Background fluctuation, unavoidably small sample size, the presence of interfering nuclides or other uncontrollable circumstances may occasionally render these LLDs unachievable. In such cases, the contributing factors are identified and described in this report. A brief description of the analyses of the different sample types and the general method of counting is discussed below. See Table 1 for the summary of the type of analyses that were performed on the different sample media.

AIRBORNE RADIOACTIVITY The filter papers collected from the field were placed on individual planchets and counted for gross beta activity in a low-background, thin-window gas proportional counter. They were analyzed at least twenty-four hours after sampling to allow for radon and thoron daughter decay. Gamma isotopic analysis was then performed on quarterly composites of the filters to determine the activity concentration of gamma emitting isotopes.

Gamma isotopic analyses were also performed on the TEDA impregnated charcoal cartridges to determine the radioiodine concentration. The cartridges and filter papers were counted for a time period such that the LLDs were met.

DIRECT RADIATION Panasonic (UDS14) TLD badges were used to measure the ambient radiation level. The TLD badges were annealed and packaged to be sent out in the field by plant dosimetry personnel. After field exposure, the TLD badges were processed on-site. The badges were calibrated using a NIST-traceable cesium-137 source.

(a) The LLD is the smallest concentration of radioactive material in a sample that will be detected with 95 percent probability with 5 percent probability of falsely concluding that a blank observation represents a "real" signal.

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

LLD =

4.6 6 sb E x V x 2.22 x Y x exp (-kt) where LLD is the lower limit of detection as defined (as pCi per unit mass or volume) sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)

E is the counting efficiency (as counts per disintegration)

V is the sample size (in units of mass or volume) 2.22 is the number of disintegrations per minute per picocurie Y is the fractional radiochemical yield (when applicable)

X is the radioactive decay constant for the particular radionuclide t is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the samples (e.g.,

potassium-40 in milk samples).

(b) LLD for drinking water.

WATER SAvIPLES Gamma isotopic analyses were performed on all water sample types. To determine the activity concentration of gamma emitters, a known volume of the water sample was analyzed using a gamma spectrometer.

Tritium analyses were performed on drinking water and surface water. The water samples were distilled and analyzed for tritium using a liquid scintillation spectrometer. Iodine-131 analysis by ion exchange was also performed on each drinking water sample.

MARINE BIOLOGICAL AND SEDIMENT SAMPLES Only the edible portion of the fish and mussels were analyzed for gamma emitters. A weighed amount of the prepared sample was analyzed using a gamma spectrometer.

The kelp blades and the pneumatocyst were prepared separately for analysis. The weighed samples were then counted on the gamma spectrometer to determine the activity concentration of gamma emitters. The results reported were based on wet weight for the marine samples.

The sediment samples were first oven-dried before performing gamma isotopic analysis. The results reported for the sediment samples were based on dry weight.

FOOD CROPS The samples were placed in appropriate counting containers and analyzed to determine the gamma isotopic content. The results obtained were based on wet weight.

MILK A known volume of the milk sample was first analyzed on a gamma spectrometer to determine its gamma isotopic content. Stable iodine carrier was then added to the milk sample for determination of chemical recovery of subsequent separation. The total iodine was separated from the sample by passing the sample through an anion resin column. The iodine was chemically extracted from the resin, precipitated as cuprous iodide and counted on the gamma spectrometer.

420DC-05. 1 9.doc 3-3

Section 4 QUALITY CONTROL Routine quality control was performed throughout the year to ensure the accuracy of equipment and procedures used in determining the results. The TES radiological laboratory also participates in an external lab performance evaluation program and in the California State Cross-Check Program.

The Nuclear Regulatory Commission (NRC) Branch Technical Position on Radiological Environmental Monitoring Programs and the DCPP Interdepartmental Administrative Procedure, RPl.IDI 1, Environmental Radiological Monitoring Procedure, requires that the TES laboratory participate in the Environmental Protection Agency's Environmental Radioactivity Laboratory Intercomparison Study or equivalent program. At the end of 1998, the EPA ceased to operate their Intercomparison Study. For the years of 1999 through 2004, TES has participated in an equivalent program operated by Analytics, Inc. of Atlanta, GA. The TES participation has included all determinations (sample medium-radionuclide combination) offered by Analytics which match those as part of the REMP.

The results of TES participation in Analytics Environmental Cross Check Program for this year are shown in Appendix A, Table A-10. Participation included analysis of:

  • gross alpha and gross beta emitters in water
  • gross alpha and gross beta emitters on particulate filter iodine-131 and gamma emitters in milk
  • tritium in water iodine-131 in charcoal cartridge gamma emitters in soil gamma emitters in vegetation iodine-131 and gamma emitters in water
  • gamma emitters on particulate filter All of the TES results of these blind samples were acceptable using the NRC criteria for determining agreement of confirmatory radiochemical measurements (See Table A-10).

The 1998 state cross-check report, "California Nuclear Power Plant Environmental Surveillance Report,"

showed that there were no discrepancies between the results obtained by the state of California Sanitation and Radiation Laboratory (SRL) and TES. The table of TES results for the 2004 cross-check program can be found in Appendix B, Table B-1. The DHS has yet to issue a report for 1999 through 2003. Since 420DC-05. 19.doc 4-1

TES has been informed that these reports have a low priority with DHS, TES requested and obtained the results from the SRL of their comparable analyses of duplicate and split samples from the DCPP environs. TES review of this data versus that of the TES laboratory for the year 2003 (the last full year of available data) showed that there continues to be good agreement between the two laboratories. TES intends to continue to perform our own comparison of the two laboratories data until the DHS resumes producing a cross-check report.

Section 5 LAND USE CENSUS Diablo Canyon Power Plant (DCPP) radiation protection personnel conducted a Land Use Census in the vicinity of DCPP for 2004. The land use census is based on Nuclear Regulatory Commission (NRC)

Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants" and 10 CFR 50 Appendix I section IV. B. 3.

DCPP Program Directive CY2, "Radiological Monitoring and Controls Program" requires performance of a land use census.

DCPP IDAP RP L.ID 11, "Environmental Radiological Monitoring Procedure", requires identification of the nearest milk animal, nearest residence, and the nearest broadleaf producing garden greater than 50 square meters (500 square feet) in each of the landward meteorological sectors within a distance of 8 kilometers (5 miles) of the plant. The land use census is conducted at least once per year during the growing season (between Feb 15 and Dec 1) for the Diablo Canyon environs.

The 2004 Land Use Census was conducted using GPS (global positioning), phone interviews, review of data from the 2003 Land Use Census, and flyover aerial survey pictures dated October 27, 2003. The flyover aerial pictures were conducted by HJW Geospatial Inc. of Oakland California. The job number was HJW #03-214. Fourteen individual landowners or tenants were contacted between July 2nd and November 29h, 2004.

No milk animals were identified within the first 8 kilometers (5 miles) of any sector.

The nearest residence, relative to all sectors, is a small trailer located in the NW sector about 1.93 kilometers (1.2 miles) from the plant. Ranch workers occupy this BLANCHARD residence approximately 1 month per year during cattle round-ups.

The nearest residence in each sector is summarized in Table B-S.

The land use census identified two household gardens greater than 50 square meters (500 square feet) that produce broadleaf vegetation. The READ garden is approximately 14 acre and located in the NNE sector at 7.08 kilometers (4.41 miles). The KOONZE garden is approximately 500 square feet and located in the E sector at 7.24 kilometers (4.5 miles).

MELLO manages a farm on the coastal plateau, along the site access road, in the ESE sector. The farm 420DC-05.19.doc 5-1

starts at approximately 4.8 km and extends to 7.2 km (3 to 4.5 miles) from the plant. This commercial farm produces no broadleaf vegetation. The farm area is about 100 acres of land with 6 to 10 rotational plantings per year (not all 100 acres planted at any one time). Commercial crops consist of about 50%

legumes (sugar peas) and 50% cereal grass (oat hay). Less than 10 farm workers periodically occupy this area during the growing season.

Much of the area outside the plant site-boundary is used for rotational cattle grazing by five separate cattle operations. For purposes of this census, the five cattle ranches are called BLANCHARD, SINSHEIMER, READ, ANDRE, and MELLO.

BLANCHARD has about 120 cattle outside the plant site-boundary and utilizes the NW, NNW, N, and NNE sectors. About 80 yearling cattle were sold to mass market in 2004; BLANCHARD did not slaughter any cattle in 2004 for personal consumption.

Additionally, BLANCHARD managed about 250 goats that were used for weed abatement in all landward sectors within the plant site-boundary. During 2004, approximately 200 baby goats were born and then taken to Santa Margarita California where they are grass fed for 1 year. After one year, the 200 yearling goats are then to be sold to mass-market auction. BLANCHARD did not slaughter any goats in 2004 for personal consumption.

BLANCHARD also managed about 60 sheep outside the plant site-boundary in the NW and NNW sectors. These sheep were sold to mass market. BLANCHARD did not slaughter any sheep in 2004 for personal consumption.

SINSHEIMER has about 100 cattle outside the plant site-boundary in the NNE sector. These cattle were allowed to breed and about 90 calves were sold to mass market in 2004. SINSHEIMER did not slaughter any cattle for personal consumption in 2004.

READ has about 150 cattle outside the plant site-boundary in the NNE sector. No cattle were sold to mass market in 2004. READ did not slaughter any cattle in 2004 for personal consumption.

ANDRE has about 80 cattle outside the plant site-boundary in the ENE sector. About 80 calves were sold to mass market in 2004. ANDRE did not slaughter any cattle in 2004 for personal consumption.

MELLO manages about 1000 cattle outside the plant site-boundary in the E, ESE, and SE sectors. Harris Ranch Beef Corporation owned these cattle and sold all of them to mass market in 2004. MELLO did not slaughter any cattle in 2004 for personal consumption.

420DC-05.19.doc 5-2

Two landowners (JOHE and ANDRE) take wild game for personal consumption outside the plant site-boundary in the NNE, NE, and ENE sectors. This wild game consists of approximately 2 deer and 4 wild pigs per landowner.

There is a California State Park Ranger Office in the NNW sector at 7.483 kilometers (4.65 miles) from the plant. Approximately 3 people occupy this office from 1000 to 1500 each day per week.

There is a public campground located in the NNW sector at Montana de Oro State Park at 7.387 kilometers (4.59 miles). This campground is near Spooner's Cove.

A total of 14 residences were identified within the 8-kilometer (5-mile) radius of the plant, which were confirmed or appear to be occupied during 2004. Ownership for powerline road cabin was changed to YOST in the 2004 Land Use Census. Two abandoned structures are located in each of the NNW and NNE sectors.

Table B-5 summarizes the nearest residences in each meteorological sector. Figure 3 shows the locations of the residences and gardens in the vicinity of DCPP.

Section 6 RESULTS AND DISCUSSION The results for the DCPP REMP are listed in Appendices A and B. The +/- terms listed in the tables in the appendices are the uncertainties within the 95 percent confidence level. The tables in Appendix A present summaries of the results, formatted in accordance with current NRC guidelines (NRC Branch Technical Position, Revision 1, November 1979). Appendix A also includes the results of the performance evaluation studies. The tables in Appendix B contain analytical results of the individual samples which were supplied to the state laboratory. The LLD for the nuclides of interest listed in Table 3 were met for all analyses.

The analytical results for the different sample types are discussed below. This discussion includes results from supplemental samples collected and analyzed. The reporting levels for radioactivity concentrations in environmental samples are listed in Table 4, page 6-8.

AIRBORNE RADIOACTIVITY Air particulates and radioiodine samples were collected weekly from six indicator stations (MT1, 0S2, 1SI, 7D1, 8SI, and 8S2) in the DCPP environs and one control station (SF1). A total of 363 airparticulate filters and 363 iodine cartridges were collected and analyzed. The data collected for the air-sampling program is summarized in Appendix A, Table A-1.

Air Particulates Gross beta activity was detected in every weekly air particulate sample collected from all indicator and control stations. The range for the indicator stations was 0.002 - 0.035 pCi/m3 with a mean of 0.012 pCi/m3. The range for the control station was 0.003 - 0.036 pCiIm3 with a mean of 0.014 pCi/m3.

Comparison of the data showed that the mean values of gross beta activities for the indicator stations were consistent with those obtained for the control station. The gross beta activities detected at the air sampling stations are tabulated in Appendix B, Table B-3 and shown in Figure 4.

Gamma isotopic analyses were performed on quarterly composites of the air particulate filters from each station. All samples collected during the year contained only naturally occurring radioactivity.

Radioiodine A total of 363 iodine cartridges were analyzed for iodine-131. No Iodine-131 was detected in any of the iodine cartridges.

DIRECT RADIATION TLD badges from 31 stations were collected on a quarterly basis and processed. A total of 372 TLD badges were distributed to field locations (three TLD badges at each location) and processed. The quarterly average exposure level from all indicator stations ranged from 9.4 - 24.8 mR/qtr with a mean of 16.9 mR/qtr. The exposure level at the control station 5F1 ranged from 16.7 - 19.3 mR/qtr with a mean of 17.7 mR/qtr. The exposure levels for 2004 did not differ significantly from the previous year, or from the pre-operational data. They indicate that the operation of DCPP did not significantly affect the ambient radiation exposure levels in the plant environs. See Appendix A, Table A-2, for the TLD data summary and Appendix B, Table BA4, for the individual station data. Figure 5 shows the long term comparisons of direct radiation exposure rates for the Inner Ring, Outer Ring, Special Interest, and Control Stations.

WATER SAMPLES A total of 60 water samples (24 drinking water samples, 36 surface water samples) were collected and analyzed. The results of the water samples collected from the indicator and control stations are summarized in Appendix A, Tables A-3 (a) and (b).

Gamma isotopic and tritium analyses were performed on all water samples. No plant related gamma emitters were detected in any surface water sample or drinking water sample. Tritium was detected in one water sample which was collected at the plant outfall (Station OUT). The result of this analysis was reviewed with the plant staff. The level of tritium detected was below the required LLD for tritium analyses in water samples. It was concluded that the detected tritium was due to a previous radwaste discharge from the plant.

Iodine-131 analysis by ion exchange was also performed on all drinking water. Iodine-131 was not detected in any drinking water samples. The water sample data indicates that the operation of DCPP did not have any significant impact on water in the plant environs.

MARINE BIOLOGICAL AND SEDIMENT SAMPLES A total of 96 marine biological and sediment samples were collected from the indicator, control and supplemental stations. They included 36 fish samples, 13 mussel samples, 45 algae samples, and 2 ocean bottom sediment samples. Table B-7 lists the marine samples collected for 2004.

from the indicator stations and control station are summarized in Appendix A, Tables A-4 to A-7. The individual samples and their detected nuclides are listed in Appendix B, Table B-2.

Abalone Red abalone were not collected in 2004. It is unlikely that abalone will be collected at DCPP in the future as the California Marine, Sport Fishing Regulations were amended on December 8, 2000 to state that no abalone can be taken south of San Francisco Bay.

California Mussels A total of 13 mussel samples were collected from stations DCM, 7C2, PON and POS. All samples contained only naturally occurring radioactivity except for one sample collected from station DCM.

Zinc-65 was detected in this sample at a level just above detection level.

Fish A total of 36 fish samples from stations DCM, 7C2, PON, POS and 7D3 were analyzed. One sample of market purchased fish obtained at 7D3 contained measurable Cs-137 attributable to environmental contamination from past atmospheric nuclear weapons testing. All other samples contained only naturally occurring radioactivity. The operation of DCPP had no detectable impact on fish in the plant environs.

Algae A total of 45 algae samples were collected from stations DCM, 7C2, PON, and POS. These samples are supplemental to the REMP. Two samples collected from DCM contained a small, but detectable level of cobalt-58. One other kelp sample collected from DCM contained measurable Zn-65. All other samples contained only naturally occurring radioactivity. The operation of DCPP had no significant impact in algae in the plant environs.

Sediment An annual sample of ocean bottom sediment was collected from stations DCM and 7C2. Only naturally occurring radioactivity was detected in these samples. The data indicated no increasing trend in isotope concentration. The operation of DCPP had no detectable impact in ocean sediment in the plant environs.

FOOD CROPS A total of 40 vegetative samples were collected from four supplemental stations: Cal Poly Farm (station 5F2), Kawaoka Farm (station 7Gl), Mello Farm (station 7Cl), and a household garden 420DC-05. 1 9.doc 6-8

(station 6C 1). All of the samples analyzed contained only naturally occurring radioactivity. The operation of DCPP had no detectable impact on food crops in the plant environs.

MILK A total of 12 monthly milk samples were collected from Cal Poly Farm, station 5F2. Iodine-131 was not detected in any of the samples. The samples contained only natural radioactivity. The operation of the plant had no detectable impact on this environmental medium.

Section 7 COMPARISON OF PREOPERATIONAL AND OPERATIONAL DATA Routine (annual) comparisons are performed on data collected for the radiological environmental monitoring program with the data collected during the preoperational period. DCPP began commercial operation in 1985. The preoperational data from the period from 1981 to 1984 are used as the preoperational baseline.

The data is analyzed using the combined Shewart-CUSUM control chart technique in which log-transformed radioactivity concentration or radiation exposure levels are compared over time. This technique assumes that the data distribution is log-normally distributed, and the log-transformed data is used in the control charts. First the data are standardized by subtracting the overall mean radioactivity level for the station from the current observation and then dividing by the overall standard deviation for that station. The control charts are used to test whether fluctuations in the standardized data are random or from a change in the concentration of a particular parameter. For air particulate gross beta activity and TLD measurements, the standardized difference between the indicator and control stations is trended on these charts.

Plant related radioactivity was detected in five sample media during 2004. Co-58 was measured in two intertidal algae samples collected from DCM. Zn-65 was measured in one kelp and one mussel sample collected from DCM. Cs-137 was measured in one sample of market fish. Tritium was measured in one water sample collected from the plant outfall, OUT. The Shewart-CUSUM control charts for the detected radionuclide-media combinations as well as air particulate gross beta activity and TLD measurements are shown and discussed below. All other CUSUM charts showed basically flat data since the last time that the radioactivity type and sampled media contained a detectible result. Detectible results noted in the past are described in the past annual report(s) in which the detectible result was initially noted.

AIRBORNE RADIOACTIVITY Air Particulates The Shewart-CUSUM control chart for gross beta activities in air particulates (see Figure 6) showed that there is no increasing trend during the operational years (1985-2004), and that the range during the operational period remained within the preoperational range (1981-1984). The high gross beta activity in 1981 was attributed to fallout from Chinese atmospheric nuclear weapons testing.

In 2004, only naturally occurring radioactivity was detected. The mean concentration of gross beta activity of the indicator stations was comparable to those of the control station. It can be concluded that the plant operations had no detectible impact on the air particulate medium.

DIRECT RADIATION The control chart for direct radiation measured by TLDs in downwind sectors on-site compared to upwind stations on-site (see Figure 7) shows that there has been no increasing trend during the operational years. The mean exposure rate measured at the stations in the downwind sectors has consistently been lower than the mean exposure rate measured at the upwind stations. This difference has remained essentially constant during both the preoperational and operational periods. The only period which shows significant differences in this long term trend was during the period between 1987 and 1990. This period was a time of high sunspot activity and rapid variations in the cosmic radiation portion of the background radiation, and also during this period the dosimeter used to measure the exposure rates in the environment was changed from Victoreen bulbs and the Panasonic badge type dosimeters. One or both of these events were the likely cause of the short term differences in the compared exposure rates.

ALGAE SAMPLES Algae sampling is not a REMP requirement and is therefore considered a supplemental sample. There is no reporting requirement for radioactivity levels in algae. Two species of algae are normally collected from DCM quarterly when available. Several times during the operational period small concentrations of various plant related radioactivity have been detected in the algae. These radioactivity concentrations detected have been random in the past so one can conclude that there is no increasing trend in radioactivity concentrations in algae from Diablo Cove. Co-58 was measured in two Iridaea samples from DCM during 2004. The control chart for Co-58 in algae (Iridaea) is shown as Figure 8.

In one sample of kelp another algae supplemental sample collected from DCM, Zn-65 was also measured. Since this is the first time that Zn-65 was detected in this media, the CUSUM value calculated indicated a significant difference from the past mean. However, the kelp sample collected in the first quarter of 2005 following this event did not contain measurable Zn-65 so there is no trend to this measurement. Stable zinc has been added to the reactor coolant at DCPP as a corrosion inhibitor for the last several years, and Zn-65 is a part of the normal plant effluent. The control chart for Zn-65 in algae (blades of kelp) is shown as Figure 9.

MUSSEL SAMPLE Zn-65 was also detected in one mussel sample collected in 2004. The mussel sample was collected from DCM. This is also the first occasion that Zn-65 was detected in this media which yields a high CUSUM value. However, the mussel sample collected after this sample did not have a measurable concentration of Zn-65, and the CUSUM value returns to the baseline. The control chart for Zn-65 in mussels is shown as Figure 10.

MARKET FISH Cs-137 was measured in one sample of fish that was purchased at a local fish market. Cs-137 has been routinely measured in fish purchased at local fish markets. This Cs-137 is most likely due to the fallout from past atmospheric nuclear test rather than being related to discharges from the plant. The control chart for Cs-137 in market fish is shown as Figure 11.

WATER SAMPLE Tritium was detected from one seawater sample collected from the plant discharge, OUT. This detected tritium was due to the recently completed discharge from the plant and did not represent the average tritium value in the discharge water.

A Shewart-CUSUM control chart was not prepared for OUT since the plant outfall is not considered an environmental sample. The radioactivity levels in the plant outfall would always be transient depending on plant release status.

Section 8 PROGRAM VARIANCE The DCPP REMP includes both required and supplemental samples. This section describes the variances with the required samples and describes some of the supplemental sampling during the year.

Subsequent to the submittal of the 2003 report, it was noted that several samples collected and analyzed for the program were inadvertently not presented in Table B-7 of that report. The description of these additional samples collected and analyzed for the 2003 report are presented on a table proceeding Table B-7 entitled Table B-7 addendum.

AIRBORNE RADIOACTIVITY The mean percent availability for all on-site and off-site samplers was 99.5 percent. That is, on average, all samplers were up and running 99.5 percent of the time. Some sampling time was lost for the following events. At station IS 1, approximately 77 hours8.912037e-4 days <br />0.0214 hours <br />1.273148e-4 weeks <br />2.92985e-5 months <br /> of sampling time was lost due to a faulty air pump during the week of 2/18 - 2/25. At station OS2, approximately 57 hours6.597222e-4 days <br />0.0158 hours <br />9.424603e-5 weeks <br />2.16885e-5 months <br /> of sampling was lost during the week of 5/5 - 5/12 due to a blown fuse. In addition, Station I S1 was not operated during the week of 2/11 -2/18 as the pump was not re-started after the previous weekly filter change.

DIRECT RADIATION During February 2004, the dosimeter location designated OSI was relocated approximately 56 feet further away from the plant in the same radial direction. This move was necessary due to plant security modifications. The previous location of this station was close to the Protected Area fence in the northwest sector.

MARINE AND TERRESTRIAL SAMPLES All marine samples were collected as scheduled (including allowable variation) except for the following:

mussel samples from Station PON were not collected during the second, third, and fourth quarters due to small size and small numbers of mussels available during these sampling periods. All terrestrial samples were collected as scheduled (including allowable variation).

As mentioned earlier, the California Department of Fish and Game has issued regulations prohibiting the collection of abalone along the central and southern coast of California. PG&E considers it unlikely that collection of abalone will be allowed in the DCPP environs in the near future. Note that the sampling of abalone is supplemental to the REMP.

420DC-05.19.doc 8-1

SUPPLEMENTAL SAMPLES As a supplement to the routine sampling program, replicate kelp samples were collected from Stations PON and POS during the fourth quarter. An additional kelp sample was collected from Station DCM in the fourth quarter also; however, the additional kelp sample was of different specie than the routine sampling for the fourth quarter.

Also as a supplement to the routine sampling program, sand samples were collected in fourth quarter from several beaches in San Luis Obispo County. These sand samples were analyzed using gamma spectrum analysis. At two of the beaches, replicate samples were collected.

Sand was collected from beaches in the following areas: Grover Beach, Pismo Beach (replicate samples), Avila Beach (replicate samples), Port San Luis, Cayucos, and Morro Bay. Cesium-137 was detected in several of the samples near the detection level for the gamma analysis technique used. The results were similar to past samples of this type and represent the ambient level of Cs-137 in the environment as the result of atmospheric nuclear testing conducted in the 1950's and 1960's. The results of the analyses of the replicate samples were within expected correlation.
