SUMMARY

S

During the year 2011, a Radiological Environmental Monitoring Program (REMP) was conducted for the Diablo Canyon Power Plant (DCPP) to assess the levels of radiation or radioactivity in the environment.

More than 1400 samples were collected (including TLDs) over the course of the monitoring period, with 0approximately 2300 radionuclide or exposure rate analyses performed.

S This report contains results from the operational Radiological Environmental Monitoring Program (REMP) for Diablo Canyon Power Plant (DCPP) compiled for the period January 1, 2011 through December 31, 2011. This program was conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RP 1.ID 11, "Environmental Radiological Monitoring Procedure."

The types of samples (matrix ID) collected for this monitoring period were as follows:

Air Particulate (AP) Air Cartridges (AC) for iodide monitoring, Direct Radiation (TLD's) Milk (MK) Meat (MT) Vegetation (VG) 0 Drinking Water (DW) Ground Water (GW) Surface Water (SW) Aquatic Vegetation (AV)

Fish (FH) Mussels (IM) Sediment (SD) Rain (ML)

S 0

Diablo Canyon REMP collected environmental samples and shipped them to General Engineering Labs (GEL) located in Charleston, South Carolina. All 2011 REMP environmental lab sample analyses were performed by GEL.

0 The ambient direct radiation levels in the DCPP offsite environs did not change and were within the S preoperational range. Beginning in June 2009, DCPP began loading of the onsite Independent Spent Fuel Storage Installation (ISFSI). The ISFSI had no significant impact on the REMP TLD station readings in the vicinity of the site boundary and beyond. The ambient direct radiation levels within the DCPP plant site boundary near the ISFSI were elevated due to dry cask used fuel storage. An evaluation of direct radiation measurements and member of public occupancy times surrounding the ISFSI indicated all federal criteria for member of public dose limits were conservatively met.

0 Groundwater monitoring data was collected in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative (August 2007). Concentrations of tritium were detected in three monitoring wells beneath the DCPP power block (OWl, OW2, and DY 1). This tritium was attributed to rain-washout of gaseous tritium exiting the plant vent system (via an approved discharge path). It should be noted that studies of the DCPP site indicated that any groundwater (subsurface) flow beneath the DCPP power block was not used as a source of drinking water. Due to topography and site characteristics, this subsurface flow discharged into the Pacific Ocean which is approximately 100 yards from the power block.

An Old Steam Generator Storage Facility (OSGSF) long term storage mausoleum was constructed within the DCPP site boundary in 2007 for storage of eight retired DCPP steam generators and two retired DCPP reactor heads. This equipment was placed into this OSGSF on the following dates:

March 2008 (outage 2R14), four DCPP Unit Two (U-2) Steam Generators

February 2009 (outage 1R15), four DCPP Unit One (U-i) Steam Generators

November 2009 (outage 2R15), one DCPP Unit Two (U-2) Reactor (Rx) Head

" October 2010 (outage 1R16), one DCPP Unit One (U-i) Rx Head This OSGSF did not cause any changes to the ambient direct radiation levels within the DCPP environs during 2011.

0 The OSGSF sumps were inspected quarterly by REMP personnel. Rainwater in-leakage was found within the OSGSF sumps during the first quarter of 2011. This rainwater had tritium concentrations of 2,000 to 34,000 pCi/Liter due to diffusion of tritium from the stored equipment into the sump rainwater. The rainwater from the sump was removed and processed via an approved radwaste discharge pathway.

Subsequent construction repairs to the OSGSF have prevented rainwater from entering the OSGSF throughout the remainder of 2011. These sumps have remained dry.

0 The results of the 2011 REMP showed no unusual findings from DCPP site operations. These results were also compared to preoperational data and showed no unusual trends.

0 On March 1 1th, 2011 the Tohoku earthquake (magnitude 9.0 Mw) and tsunami struck the east coast of Japan. The tsunami associated with this event caused nuclear accidents at the Dai-Ichi Nuclear Power Station in Fukushima Prefecture, Japan. Isotopic releases occurred in Japan and were carried by the jet stream to the west coast of the United States. The DCPP REMP initiated numerous supplemental sampling to establish Fukushima contributions to DCPP isotopic background concentrations. These 0

Fukushima isotopes were eventually detected by the DCPP REMP beginning on March 17 th, 2011. The

primary isotopes detected by the DCPP REMP were 1-13 1, 1-132, Te-132, Cs-134, and Cs-137. Airborne O concentrations were detected from March 17 th thru April 2 0 th. The DCPP REMIP continued to detect 0 cesium within milk, vegetation, and meat throughout the end of 2011. Additional discussion on

Fukushima isotopes is found within Section 4.5 of this report.

1.0 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.

S

Radiological Environmental Monitoring Program (REMP) samples were collected by DCPP REMP personnel and sent to General Engineering Labs in Charleston, South Carolina for analysis. Fish (except market fish) and ocean sediment samples were collected by contract divers of Tenera Environmental and given to DCPP REMP personnel for shipment to GEL. Market fish samples were collected by local commercial fishermen and then purchased by DCPP REMP personnel in one of two local fish markets for

shipment to GEL. Direct radiation analyses were conducted by DCPP REMP personnel and analyzed by the

DCPP Thermoluminescent Dosimeter (TLD) Lab.

DCPP sent replicate samples of milk (5F2), drinking water (DWI), outfall water (OUT), Diablo

Creek (5S2), vegetative crops (7G1), fish (DCM), sediment (DCM), and kelp (DCM) to the California

Department of Public Health (CDPH) Radiological Health Branch as part of a State cross check program.

Other pathways monitored independently by the CDPH were direct radiation (TLDs) and air sampling.

Additional split sampling was conducted post Fukushima Japan, Dai-Ichi NPS accident time frame.

This report summarizes the quarterly findings of the Radiological Environmental Monitoring

Program (REMP) conducted by Diablo Canyon Power Plant. The remainder of this report is organized as

2.0 PROGRAM DESIGN 0 The Radiological Environmental Monitoring Program (REMP) for the Diablo Canyon Power Plant (DCPP) was designed with the following specific objectives in mind. These objectives continue to be in force, to varying degrees, throughout facility operation.

" To provide an early indication of the appearance or accumulation of any radioactive material in the environment caused by facility operation. Preoperational data is also used in this comparison.

0

" To provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits.

0

To provide standby monitoring capability for rapid assessment of risk to the general public in the event of unanticipated or accidental releases of radioactive material.

0 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, ocean sediment, and invertebrates. Supplemental samples such as algae, kelp, local agricultural crops, recreational beach sand, groundwater, meat, and milk were also collected. The sampling locations were determined by land use, site meteorology, and local demographics. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Radiological Environmental Monitoring, Revision 1, November 1979 The detailed sampling requirements of the RENT are given in Table 2.1 of this report. Summaries of REMP sampling for the period are shown in Appendix A of this report. Direct dose (environmental TLDs) results are shown in Appendix B of this report. The REMP sample isotopic results are shown in Appendix C of this report. Any deviations from the REMP sampling schedule / requirements are documented in section 4.0 of this report.

2.1 MONITORING ZONES The REMP was designed to allow comparison of levels of radioactivity in samples from the areas possibly influenced by DCPP to levels found in areas not influenced by the facility operations. Areas with the potential to be influenced by facility operations are called "indicator" stations. Areas with sufficient distance from the plant that are not likely to be influenced by facility operations are called the "control" stations. The distinction between the two zones is based on distance and relative direction from the plant. Analysis of survey data from the two zones aided in determination of site environmental influence. It also helped in differentiation between radioactive releases and seasonal variations in the natural environmental background.

2.3 DESCRIPTION

S OF REMP MONITORING 2.3.1 Direct Radiation Direct ambient radiation was measured at 31 stations in the vicinity of DCPP using

Panasonic UD814 TLD badges. The TLD badges had valid element correction

factors (ECF), were calibrated using a NIST-traceable cesium-137 source, were annealed prior to placement, and were sealed in watertight packaging. Three badges

were placed at each station each quarter. These badges were replaced on a quarterly

basis.

Direct ambient radiation was measured at 8 stations in the vicinity of the ISFSI

using Panasonic LTD814 TLD badges. The TLD badges had valid element correction factors (ECF), were calibrated using a NIST-traceable cesium- 137 0 source, were annealed prior to placement, and were sealed in watertight packaging.

Three badges were placed at each station each quarter. These badges were replaced on a quarterly basis.

The field TLD badge packets were prepared and processed by DCPP personnel and the DCPP TLD Lab. Control badges were carried with the field badges to measure 0 any dose received during transit. The location, date, and time of exchange were

recorded on a log sheet which accompanied the field badges. The net exposure was reported over a standard 90 day quarter.

DCPP Environmental TLD standard quarter results are measurements of all environmental gamma radiation sources (cosmic, terrestrial, radon, etc) at each

station during the deployment period. Transient and lab storage background dose

contributions were subtracted prior to reporting.

0 2.3.2 Airborne Radioactivity 0 Air particulate and radioiodine sampling were performed weekly at six indicator stations: MT1, 0S2, 151, 7D1, 8S1 and 8S2. Air particulate and radioiodine sampling was performed weekly at one control station: 5F 1.

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 standard cubic feet per minute. The air samplers were located approximately one meter above the ground. The sample volumes were determined by F&J Corporation model DF- I flowmeters (corrected to standard temperature and pressure, STP) which were installed downstream of the sample head. At the end of the sampling period (weekly), the filter and cartridge were collected. All necessary data regarding the air volume readings, flowrate, sampler time on / off, date of collection, and sampler location were recorded and submitted to GEL along with the samples for analysis.

Approximately 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months after sampling (to allow for radon and thoron daughter decay), 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. Gamma isotopic analysis was then performed on quarterly composites of the filters (by station) to determine the activity concentration of gamma emitting isotopes. The quarterly composite is reported at the midpoint of the quarter monitored.

The TEDA impregnated charcoal cartridges were counted for each weekly station sampling period for gamma isotopic analyses to determine the radioiodine concentration.

2.3.3 Waterborne Water samples (drinking water, surface water, monitor wells, and groundwater) were collected at the frequencies shown in Table 2.1 Ocean surface water samples were collected at Diablo Cove (station DCM),

Rattlesnake Canyon (station 7C2), and at the plant Outfall (station OUT).

Drinking water samples were collected from Diablo Creek Weir (station 5S2),

Diablo Creek Outlet (station WN2), Blanchard Spring (station 1A2), and from the DCPP drinking water system (station DWl). Drinking water was also collected from a control station located in San Luis Obispo at the Offsite Emergency Lab (station OEL).

Supplemental groundwater samples were collected from Water Well 02 (WW2) and DCSF96-1 (8S3).

Supplemental onsite monitoring well samples were collected from Observation Well 01 (OWl), Observation Well 02 (OW2), and a french drain system labeled Drywell 115 (DY 1). These shallow wells were located in close proximity to the facility power block structures and within the protected area.

S After collection, the samples were securely sealed and labeled with sample type, station ID, date, time of collection, person performing the collection and sent to GEL for analysis.

0 2.3.4 Marine Biological, Beach Sand, and Ocean Sediment

The REMP required sampling of rockfish (family Sebastes), perch (family Embiotocidae), mussels (family Mytilus), and ocean sediment from indicator

station DCM and control station 7C2. All other marine samples collected were considered supplemental. These supplemental marine samples included the following: intertidal algae, intertidal mussels, kelp, and market fish. The intertidal

samples were collected by DCPP personnel during low tidal conditions. Kelp was

collected quarterly by DCPP personnel from the offshore kelp bed in the vicinity of the plant. Quarterly samples of fish and an annual sample of ocean sediments were

collected from the plant environs by contracted divers (TENERA Environmental).

The Tenera divers fillet the fish and leave a small portion of skin for identification.

Beach sand was collected by DCPP personnel between the high and low tide boundaries at nearby recreational beaches. Fish caught locally by commercial

fishermen were purchased from two local fish markets (Avila Beach Pier-7D3 and Morro Bay-2F1).

All samples were subject to unavailability due to seasonal fluctuations or unfavorable sampling conditions. The above samples were sealed in plastic bags

immediately upon collection. Mussels were sent to GEL in-shell where GEL

personnel removed the meat & internal organs for analysis. Only edible portions of the fish were analyzed (fish fillets). The samples were labeled with sample Stype, station ID, date, time of collection, and the individual who performed collection. The samples were then frozen (to prevent spoilage odor) before they were sent to GEL for analysis.

2.3.5 Food Crops The REMP required broadleaf food vegetation to be collected in the nearest off-site locations of the highest calculated annual average ground level D/Q

(dispersion parameter) within 5 miles. There was no broadleaf food vegetation available that satisfied this requirement. Because these food products were unavailable, the DCPP REMP conducted additional air sampling in the SE (station 8S2) and NNW (station 1S1) sectors. Additional representative samples

of food crops in season were collected monthly from supplemental stations: Cal Poly Farm (5F2), Kawaoka Farm in Arroyo Grande (7G1), Mello Farm (7C1)

along the site access road, and quarterly household gardens (3C1 and 6C1).

0 The monthly samples (including 3C 1) were collected by DCPP personnel and

sealed immediately in plastic bags. The quarterly household garden sample (6C 1)

was provided to DCPP personnel by the land occupant (due to property access difficulty and privacy). The samples were labeled with sample type, station ID, collection date, collection time, and the individual who performed collection. The

samples were normally frozen before they were sent to GEL for analysis (to

prevent spoilage odor).

2.3.6 Milk There were no animals within the vicinity of the plant that were utilized for milk consumption by humans. However, supplemental samples of cow milk were collected monthly from Cal Poly Farm (5F2) which was approximately 13 miles from DCPP. Two 1-gallon plastic containers of milk were collected each sampling period by DCPP personnel. Forty grams of sodium bio-sulfite preservative were added to each gallon of milk sample. The containers were sealed and shaken thoroughly to distribute the preservative. The containers were labeled with sample type, station ID, collection date, collection time, and the individual who performed collection. The samples were then express shipped to GEL for analysis.

2.3.7 Meat A rancher routinely grazed cattle, goats, and sheep within three miles of the site boundary. These livestock meats were offered at local farmer's markets and private distribution. This meat commodity began at the end of 2007. REMP personnel obtained meat samples of each species directly from the land owner.

Gamma spec and strontium analyses were performed on the meat.

Additional Fukushima Japan event meat sampling was conducted of Hearst Ranch meat which is located approximately 37 miles north of the DCPP site. This Hearst Ranch meat is free range, grass fed beef. This new REMP station code was HCM and provides a control location far from the site. REMP personnel purchased this Hearst Ranch meat directly from local grocery stores.

Property owners could hunt deer and wild pig (in season) within 5 miles of the site boundary. The REMP obtained one deer meat sample from these property owners. Gamma spec and strontium analyses were performed on the deer meat.

The meat was initially packaged by the livestock owners and turned over to REMP personnel. The packages were then separated by species and placed in large zip-lock bags. Each bag was labeled with sample type, station ID, collection date, collection time, and the individual who performed the collection.

The samples were then frozen and sent to GEL for analysis.

Table Notations

1. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to circumstances such as hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons.

If specimens are unobtainable due to sampling equipment malfunction, effort shall be made to complete corrective action 0 prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual 0 Radiological Environmental Operating Report. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances, suitable specific alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made 0 within 30 days in the Radiological Environmental Monitoring Program, and submitted in the next Annual Radioactive Effluent Release Report, including a revised figure(s) and table for the ERMP reflecting the new location(s) with 0 supporting information identifying the cause of the unavailability of samples for that pathway and justifying the section of the new location(s) for obtaining samples.

0 2. For the purposes of this table, a thermoluminescent dosimeter (TLD) is considered to be one phosphor. There are normally three calcium sulfate phosphors in an environmental TLD BADGE. Film badges shall not be used as dosimeters for 0 measuring direct radiation.

3. Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow 0 for radon and thoron daughter decay. If gross beta activity in air particulate samples is greater than 10 times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

4. Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.

5. If broadleaf vegetation food products are unavailable, additional air sampling as specified in Table 2.1, Parts 2 & 3 will be done in the SE (Station 8S2) and NNW (station IS1) sectors.

6. The Branch Technical Position (Nov 79) states, "Any location from which milk can no longer be obtained may be dropped from the surveillance program after notifying the NRC in writing that they are no longer obtainable at that location".

Although milk sampling performed at 5F2 is outside the 5-mile radius and is supplemental to the REMP, this notification should take place if 5F2 milk sampling ceases.

3.0 RADIOLOGICAL DATA-

SUMMARY

OF TABLES This section summarizes the analytical results of the environmental samples, which were collected 0during the monitoring period. The results, shown in Appendix A, are presented in a format similar to that prescribed in the NRC's Radiological Assessment Branch Technical Position on Environmental Monitoring. The results are ordered by sample media type and then by radionuclide.

Each table is nuclide specific, and the total number of analyses for that radionuclide during the monitoring period, are provided. Additionally, the number of measurements which exceeded the

Reporting Levels (NRC Notification Level) found in Table 2.4 of this report are provided. The first column lists the matrix or pathway sampled during the period. The second column lists the nuclides analyzed and number of samples performed. The third column provides the required a-priori Lower Limit of Detection (LLD) for radionuclides that have detection capability requirements as specified in Table 2.3 of this report. The sixth and seventh columns contain the mean and average results for locations. The eighth column contains the number for reportable occurrences for the location pathway. Occasionally, the required LLD is not met. An example of this occurrence might be due to hold times between sampling and analysis. Such cases, if any, are addressed in Section 4.0 of this report.

The Minimum Detectable Concentration (MDC) listed for each analysis in Appendix C was used as an evaluation point for samples collected in the calendar year. The MDC was calculated by the Slaboratory with each analysis (a-posteriori) and incorporates conditions observed at the laboratory during the analysis. This MDC value mathematically represents the lowest concentration of activity that can be detected by the laboratory with a 95% confidence level. The MDC is also understood as 0the concentration where there is only a 5% probability of falsely reporting a positive detection in a true blank sample. Note that the MDC equation used by the environmental lab is equivalent to the Lower Limit of Detection (LLD) equation specified in NUREG 1301. For this report, a sample is considered to yield a 'detectable measurement" when the "result" concentration exceeds the

associated MDC value.

Additionally, the tables of Appendix A provide the mean of all sample results analyzed for the specified radionuclide/ media type, the range, and the number-of samples that were considered to Shave detectable activity of all the samples counted.

0 The mean value consists of the average of detectable concentrations.

0 The lowest and highest detected concentration values were listed

The number of detectable measurements and the total number of measurements were listed. For example, (4/20) would indicate that 4 of the 20 samples collected, for that 0sample type and that radionuclide, contained detectable radioactivity.

0 The radionuclides reported in this section represent those that:

had an LLD requirement in Table 2.3 of this report, or a Reporting Level listed in Table 2.4

were of specific interest for any other reason 0The radionuclides routinely analyzed and reported for a gamma spectroscopy analysis are: Ac-228,

Ag-1 10m, Be-7, K-40, Ce-144, Co-57, Co-58, Co-60, Cr-51, 1-131, Cs-134, Cs-137, Ba-140, La-140, Fe-59, Mn-54, Nb-95, Ru-103, Rh-106, Sb-124, Sb-125, Zn-65, and Zr-95.

Data from direct radiation measurements made by TLD are also provided in Appendix A in a similar format described above. Actual quarterly TLD results are listed in Appendix B.

Additional supplemental REMP sampling was conducted in 2011 for the Fukushima Prefecture Japan, Dai-Ichi NPS nuclear accidents. This Fukushima event sampling data is also provided in Appendix A tables as described above.

0 4.0 ANALYSIS OF ENVIRONMENTAL RESULTS 0

4.1 REMP Sampling Variance / Deviations The DCPP Radiological Environmental Monitoring Program allows for deviations in the REMP sampling schedule "if samples are unobtainable due to hazardous conditions, seasonal unavailability, or malfunction of sampling equipment." Such deviations do not compromise the program's effectiveness and are normally anticipated for any radiological environmental monitoring program.

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.

4.1.1 DIRECT RADIATION There were no abnormal affects to the 2011 station environmental TLD results.

Previous reporting errors were made in the 2009 and 2010 AREORs for stations 1Al and 4S1.

Corrections are as follows:

2009 1A1 reported total dose was 48.5 mrem ; corrected total dose is 47.4 mrem.

2009 1A1 reported average dose was 12.1 mrem ; corrected average dose is 11.9 mrem.

2009 1A1 reported standard deviation was 0.9 ; corrected standard deviation is 0.7.

2009 1A1 reported 2x standard deviation was 1.7 ; corrected 2x standard deviation is 1.5.

2009 4S1 reported total dose was 80.5 mrem ; corrected total dose is 76.7 mrem.

2009 4S1 reported average dose was 20.1 mrem ; corrected average dose is 19.2 mrem.

2009 4S1 reported standard deviation was 1.2 ; corrected standard deviation is 0.6.

2009 4S1 reported 2x standard deviation was 2.5 ; corrected 2x standard deviation is 1.3.

2010 lA1 reported total dose was 48.5 mrem ; corrected total dose is 45.1 mrem.

2010 1Al reported average dose was 12.1 mrem; corrected average dose is 11.3 mrem.

2010 1A1 reported standard deviation was 0.9 ; corrected standard deviation is 1.2.

2010 1AI reported 2x standard deviation was 1.7 ; corrected 2x standard deviation is 2.4.

2010 4S 1 reported total dose was 80.5 mrem ; corrected total dose is 74.4 mrem.

2010 4S 1 reported average dose was 20.1 mrem; corrected average dose is 18.6 mrem.

4.1.2 AIRBORNE RADIOACTIVITY The mean percent availability for all on-site and off-site air samplers was 99.9 percent. This means, on average, all air samplers were up and running 99.9 percent of the time. The remaining S0.1 percent can be attributed to equipment problems, filter exchange, and calibration processes.

Actual percent availability for each station were as follow:

0S2 = 99.9,%

1S1 = 99.9 %

0 4.1.3 MARINE SAMPLES All marine samples were collected as scheduled (including allowable variation).

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 is unlikely that 0collection of abalone will be allowed in the DCPP environs in the near future. The REMP has therefore ceased routine abalone sampling. Note that the sampling of abalone was previously performed and was supplemental to the REMP.

4.1.4 TERRESTRIAL SAMPLES All terrestrial samples were collected as scheduled (including allowable variation).

4.1.5 OCEAN SURFACE WATER, DRINKING WATER, AND GROUNDWATER All water samples were collected as scheduled (including allowable variation).

0 4.1.6 REPLICATE SAMPLES Replicate sampling is conducted within the REMP for program strength and correlation.

Replicate samples were taken from 5F2 Vegetation (3/28/11), 5F2 Milk (3/21/11),

DYi Water (3/14/11), 7C2 Water (6/13/11), and OEL Drinking Water (9/29/11). The results of the analyses were within expected correlation.

0 4.2 COMPARISON OF ACHIEVED LLDS WITH REQUIREMENTS For each analysis having an LLD requirement, criteria for the calculated "a priori" (before the fact) LLD were met during the sampling and analysis process. Meeting these process criteria satisfies the "a priori" LLD requirements. The "a posteriori"(after the fact) Minimum Detectable Concentration (MDC) for that analysis was also compared with the required "a priori" (before the fact) LLD.

Table 2.3 of this report gives the required "a priori" Lower Limits of Detection (LLDs) for environmental sample analyses required by the DCPP Radiological Environmental Monitoring Program. Occasionally an LLD is not achievable due to situations, such as hold times between sampling and analysis. In such a case, a discussion of the situation is provided.

The supplemental Fukushima event air sampling was conducted with different protocols than the normal REMP sampling and therefore the normal REMP LLDs may or may not apply. For example, the REMP increased Fukushima event sampling air flow (2.0 scfmn) which resulted in increased sample volumes during those time periods. The Fukushima sampling event particulate filters were analyzed at the end of each week (instead of quarterly) which destroyed the filters for strontium analysis.

S All other REMP samples analyzed met the specific "a-priori" LLD requirements in 2011.

4.3 COMPARISON OF RESULTS AGAINST REMP REPORTING LEVELS 0 Notification is required whenever a Reporting Level in Table 2.4 of this document is exceeded.

Reporting Levels are the environmental concentrations that relate to the ALARA design dose objectives of 10 CFR 50, Appendix I. It should be noted that environmental concentrations are averaged over calendar quarters for the purposes of this comparison, and that Reporting Levels apply only to measured levels of radioactivity due to DCPP plant related effluents.

No REMP Reporting Levels were exceeded during this monitoring period.

0 It should be noted that Fukushima Japan event related isotopes are not DCPP plant related effluents and therefore do not apply to these reporting levels.

4.4 DATA ANALYSIS BY MEDIA TYPE

The REMP data for each media type is discussed below. A sample is considered to yield a "detectable measurement" when the result concentration exceeds the MDC for that analysis.

4.4.1 Direct Radiation (Environmental TLDs)

Direct radiation is continuously measured at 31 locations surrounding DCPP using Panasonic UD-814 thermoluminescent dosimeters (TLDs). These 31 locations are made up of 29 indicator stations & 2 control stations. These dosimeters are collected every calendar quarter for readout at the DCPP TLD Lab. The results are trended with preoperational and historical operating values for adverse trends.

DCPP Environmental TLD standard quarter results are measurements of all environmental gamma 0radiation sources (cosmic, terrestrial, radon, etc) at each station during the deployment period.

Transient and lab storage background dose contributions were subtracted prior to reporting.

It should be noted that the following Environmental TLD locations are all within the DCPP site boundary and are not located within the unrestricted area :0S1, 0S2, WNl, 1S1, 2S1, 3S1, 4S1, 5S1, 5S3, 6S1, 7S1, 8S1, 8S2, 9S1, MT1, and IS1 through IS8. The unrestricted area surrounding DCPP is sparsely inhabited out to five miles from the site (see 2011 Land Use Census). The

ambient direct radiation levels within the DCPP plant site boundary (approximately 800 meter radius from U- I CTMT structure) were elevated due to dry cask used fuel and radioactive material storage. An evaluation of direct radiation measurements and member of public occupancy times

within the site boundary indicated all federal criteria f6r member of public dose limits were conservatively met.

The first graph provided below illustrated overall trending of environmental TLDs with regard to distance from the DCPP plant site. Inner ring, outer ring, special interest, and control stations were Scombined and averaged to obtain a single standard quarter value for each plot line represented. It should be noted that inner and outer ring TLD averages remain within and trend with pre-operational ranges. It should also be noted that ISFSI loading and the Fukushima Japan nuclear 0accidents have not affected these inner and outer ring trending results.

The second graph provided below illustrated averaged environmental TLD results from the northwest (stations OS 1, 0S2, OB 1) and southeast (stations 8S1, 8S2) sectors. These sectors were chosen for graphical trending due to historical wind rose results for the site. The northwest and 5southeast sectors have been the highest historical averaged wind directions and therefore would have the most impact on environmental TLD results. Averaged control stations (4D 1, 5F 1) were provided for reference.

0Appendix B provides individual station environmental TLD standard quarter dose results.

Appendix B also provides an individual station historical average along with low/high ranges from 1987 to 2010 for comparison of the 2011 data.

No adverse trends were noted in 2011 Environmental TLD monitoring.

0 0 Direct radiation is also continuously measured at 8 stations surrounding the Independent Spent Fuel Storage Installation (ISFSI) using Panasonic UD-814 thermoluminescent dosimeters (TLDs). These 8 stations are located directly adjacent to the ISFSI protected area, with 2 stations on each of the 0 four sides of the ISFSI pad. It should be noted that these stations and the ISFSI are well within the DCPP site boundary and are not located within the unrestricted area. These dosimeters are collected 0 every calendar quarter for readout at the DCPP TLD Lab. The first spent fuel canister was loaded 0 onto the ISFSI pad in June 2009. The small increase in radiation levels at the ISFSI pad prior to spent fuel canister load was due to storage of Radioactive Material (RAM) equipment in seatrains at the ISFSI pad prior to an outage. These seatrains of RAM were removed prior to the first load of 0 spent fuel canisters. In May 2010, DCPP began the second ISFSI loading of spent fuel canisters.

The ambient direct radiation levels within the DCPP plant site boundary near the ISFSI were 0 elevated due to dry cask used fuel storage. An evaluation of direct radiation measurements and member of public occupancy times surrounding the ISFSI indicated all federal criteria for member 0 of public dose limits were conservatively met. No adverse trends were noted at the DCPP inner ring stations due to ISFSI for 2011 as indicated by the previous graphs. It should be noted that the DCPP 0 inner ring TLD results tracked in correlation with normal Environmental TLD outer ring, special interest, and control station fluctuations. It should also be noted that DCPP inner ring TLD results remain within pre-operational ranges.

4.4.2 Airborne Air particulate and radioiodine samples were collected weekly from six indicator stations (MT 1, 0S2, ISI, 7D1, 8S1, and 8S2) in the DCPP environs and one control station (5F1). A total of 364 air particulate filters and 364 iodine cartridges were collected and analyzed as part of the normal REMP. Additional air sampling was conducted from 3-16-11 through 5-4-11 due to the Fukushima Japan nuclear accidents. The data collected for the air sampling program is summarized in Appendix A, Appendix C, and Appendix D..

Gross beta activity was detected in almost every weekly air particulate sample collected from all indicator and control stations. 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 and historical trending. Normal background gross beta values range from 2E-3 to 9E-2 pCi/m3. The gross beta activities detected at the air sampling stations are tabulated in Appendix A.

Gamma isotopic analyses were performed on quarterly composites of the air particulate filters from each of the normal REMP stations. The Fukushima event supplemental air samples were analyzed individually at the end of each week. 1-131, 1-132, Te-132, Cs-134, and Cs-137 were detected in REMP and Fukushima event supplemental air sampling in March, April, and May.

These isotopes originated from the Fukushima Japan nuclear accidents and were transported to the west coast of the United States via the jet stream. It should be noted that the 2-12-11 identification of isotopes is due to the quarterly analysis midpoint reference of the first quarter of 2011. Therefore, isotopes captured on normal REMP particulate filters in March (after the Fukushima event) were counted with the other REMP filters from the first quarter and the midpoint date assigned. Appendix A summarizes those results.

A total of 364 normal REMP weekly charcoal cartridges were analyzed for Iodine- 131.

Additional Fukushima event air sampling was also conducted from 3-16-11 through 5-4-11.

Iodine-131 was detected in these charcoal cartridges during these date ranges due to the Fukushima Japan nuclear accidents. These isotopes were transported to the west coast of the United States via the jet stream. The supplemental Fukushima event air sampling was conducted at an increased flow rate (2.0 scfm) and increased volume.

No Iodine- 131 was detected in any of the remaining station charcoal cartridges after 5-4-11.

Appendix A summarizes normal REMP and Fukushima event supplemental air sampling results.

0 4.4.3 Drinking Water, Ocean Surface Water, and Groundwater Drinking Water Drinking water samples were collected from stations DW1, 5S2, WN2, 1A2, and OEL (control location). The samples were analyzed for gamma emitters, gross beta, tritium, Total Strontium, Iron-55, and Nickle-63.

No plant related radionuclides were detected in any of the drinking water samples.

The results of the water samples collected from both the indicator and control stations are summarized in Appendix A.

0Groundwater

As part of the nuclear industry NEI 07-07 Groundwater Protection Initiative (GPI), DCPP began sampling Various water sources in 2006. These sources included onsite monitoring wells (OWl,

OW2, DY1, & 8S3), an aquifer well (WW2), a creek (5S2 & WN2), and a groundwater spring

(1A2).

Two groundwater aquifer wells are available within the plant site boundary; Water Well 01 and

Water Well 02. These wells are located about 115' above and to the east of the power block.

Water Well 01 was abandoned and the well pump was inoperable. Water Well 02 was sampled and only naturally occurring isotopes were detected.

One shallow (approximately 70 feet deep) subsurface monitoring well was located Southeast at

approximately 0.3 miles from the power block. This monitoring well is labeled DCSF96-1 (8S3).

No tritium or plant related isotopes were found in the 8S3 monitoring well during 2011.

Stations 5S2, WN2, and 1A2 were discussed in the previous Drinking Water paragraph.

Three shallow (approximately 37 to 73 feet deep) subsurface monitoring wells are located within the plant protected area and in close proximity to the containment structures, spent fuel pools, and

auxiliary building (plant power block). These monitoring wells are labeled Observation Well 01 (OWl), Observation Well 02 (OW2), and Drywell 115 (DY1). Due to rainwater washout of gaseous tritium exiting the plant vent system (via an approved discharge path), these monitoring

wells contained low levels of tritium throughout 2011. Further reporting of these monitoring wells was provided in Section 5.2 of this report.

Two additional groundwater monitoring wells were installed along the western side of the DCPP site on December 14, 2011. These wells were not ready for sampling in 2011. Future sampling will begin in the 2012 AREOR. For informational purposes, drill tailing sediment samples were

obtained during the drilling process and analyzed for gamma spec. The drill tailing sediment samples are reported within this 2011 annual report within Appendix C. The new well station names are GW 1 and GW2.

0 4.4.4 Ingestion

Marine Biological Samples Fish samples were collected quarterly from stations DCM, 7C2 (control), PON, POS, and a local market (7D3 or 2F1). Mussels were collected quarterly from stations DCM, 7C2, and POS. Mussels were collected annually from station PON. A summary of these samples (required and supplemental) is described in Table 2.1. A summary of sample results is provided in Appendix A.

0 0

0

0 1-131 was detected in mussels at station 7C2 on 3-23-11 due to rain washout of Fukushima Japan 0 event isotopes. The 7C2 sampling station is located at the discharge of a creek into the Pacific Ocean. The watershed for this creek caused large concentrations of 1-131 to be available for mussel uptake. See Fukushima rain 1-131 sampling results in Appendix A. These isotopes were transported from Japan to the west coast of the United States via the jet stream.

All other marine fish and mussel samples did not detect any DCPP related radionuclides during 2011.

Marine Aquatic Vegetation Supplemental marine aquatic kelp sampling was performed quarterly at REMP sample stations DCM, PON, POS, and 7C2 (control). No DCPP related isotopes were detected in 2011.

Supplemental intertidal algae sampling was performed quarterly at RENT sample stations DCM and 7C2 (control). No DCPP related isotopes were detected in 2011.

Each sample was analyzed for gamma emitting radionuclides. A summary of the sample results is provided in Appendix A.

Ocean Sediment and Recreational Beach Sampling Ocean sediment samples were collected annually from stations DCM and 7C2. Gamma Spec, Total Strontium, Iron-55, and Nickle-63 were analyzed.

Supplemental recreational beach sand samples were collected semi-annually from stations Avila Beach (AVA), Montana de Oro Spooner's Cove (MDO), Pismo Pier Beach (PMO), Cayucos Morro Strand State Beach (CYA), and Cambria Moonstone Beach (CBA). Each sample was analyzed for gamma emitting radionuclides, Total Strontium, Iron-55, and Nickle-63.

Only natural occurring isotopes where detected in the ocean sediment and recreational beach sand samples collected for 2011.

4.4.5 Food Crops (Vegetation)

Samples of broad leaf vegetation were collected monthly (when available) from two indicator stations (7C1 and 7G1), and one control location (5F2). Samples were collected quarterly from residence gardens at stations 3C 1 and 6C 1. The samples were analyzed for gamma emitting radionuclides and for Iodine- 131 on edible portions.

1-131, Cs-134, and Cs-137 were detected in these vegetation samples due to the Fukushima Japan nuclear accidents. These isotopes were transported to the west coast of the United States via the jet stream.

0 As further control sampling, supplemental Fukushima event vegetation sampling was conducted in Atascadero, California (20 miles north of DCPP). These Fukushima related isotopes were also detected in various vegetation samples at this control station. A summary of the sample results are provided in Appendix A.

4.4.6 Milk There are no milking animals within 5 miles of the plant site. In cases where milk sampling is not available, the REMP program permits the collection of broad leaf vegetation from three sample 0

0 0

0 locations in place of milk. Since broadleaf sampling is also not available in the DCPP environs, the

DCPP REMP requires additional air sampling at stations 8S2 and IS 1.

Supplemental samples of milk were collected monthly from Cal Poly Farm (station 5F2). The samples were analyzed for gamma emitting radionuclides, Iodine- 131, and Total Strontium. Milk samples were collected monthly from station 5F2 regardless of the availability of milk stations

within 5 miles of the plant.

1-131, Cs-134, and Cs-137 were detected in these milk samples due to the Fukushima Japan nuclear accidents. These isotopes were transported to the west coast of the United States via the jet stream.

Vegetation uptake and subsequent digestion by the cows were the source of these isotopes into the

milk. A summary of the sample results are provided in Appendix A.

4.4.7 Meat Products Meat products were collected quarterly (when available and provided) from landowners.

Samples of livestock meat were collected from the Blanchard Ranch in 2011. These samples were Blanchard cow meat (BCM), Blanchard sheep meat (BSM), and Blanchard goat meat (BGM).

One wild deer meat sample was supplied by a landowner in 2011.

Additional Fukushima Japan event meat sampling was conducted of Hearst Ranch meat which is located approximately 37 miles north of the DCPP site. This Hearst Ranch meat is free range, grass 0fed beef. This new REMP station code was HCM and provides a control location far from the site.

Cs-134 and Cs-137 were detected in these meat samples due to the Fukushima Japan nuclear accidents. These isotopes were transported to the west coast of the United States via the jet stream.

Vegetation uptake and subsequent digestion by the animals were the source of these isotopes into the meat. A summary of the sample results are provided in Appendix A.

4.5 SUPPLEMENTAL ENVIRONMENTAL SAMPLING AND ISOTOPIC DETECTION

DUE TO THE FUKUSHIMA PREFECTURE JAPAN, DAI-ICHI NUCLEAR POWER STATION

ACCIDENTS.

0 On March 11 th, 2011 the Tohoku earthquake (magnitude 9.0 Mw ) and tsunami struck the east coast of Japan. The tsunami associated with this event caused nuclear accidents at the Dai-Ichi Nuclear Power Station in Fukushima Prefecture, Japan. Isotopic releases occurred in Japan and were carried by the jet stream to the west coast of the United States.

The DCPP REMP initiated numerous supplemental sampling to establish Fukushima contributions to DCPP isotopic background concentrations. Supplemental DCPP environmental sampling

included the following:

0

Capture of rain in March and April for isotopic analysis (see Appendix A & D) 0 Additional air sampling at stations 0S2, 5F1, 7D 1, and 8S 1. This air sampling was conducted with additional air samplers at an increased flow rate (2.0 scfm) and increased 0volumes. The station samples were analyzed each week for gamma isotopic and strontium

which is different than normal REMP sampling protocols (see Appendix D) 0 0

0 0

Additional milk and vegetation sampling was conducted at station 5F2 (Appendix A & C). 0

" Additional vegetation sampling was conducted outside the possible influence of DCPP within Atascadero, California (20 miles north of DCPP). Fescue grass, milk thistle, miner's lettuce, and acorns were sampled in Atascadero (station ATAS) to establish additional control vegetation samples (see Appendix D).

" Additional meat control sampling was conducted outside the possible influence of DCPP at Hearst Ranch which is located 37 miles north of DCPP near San Simeon, California.

Publically offered Hearst Ranch meat (station HCM) was free range, grass fed beef and provided a control for Blanchard meat (stations BCM, BSM, and BGM). The HCM sampling was provided in Appendix A & C.

Sticky pads (1ft by 3ft) were placed at 0S2 and 5F 1 to monitor ground deposition of Fukushima isotopes. These sticky pads were pulled weekly from 3-23-11 until 5-4-11 for isotopic analysis (see Appendix A & D).

Fukushima related isotopes were detected by the DCPP REMP beginning on March 17'h, 2011.

The primary Fukushima related isotopes detected by the DCPP REMP were 1-131, 1-132, Te- 132, Cs-134, and Cs-137.

Airborne isotopic concentrations were detected from March 17kh thru April 20tb.

The DCPP REMP continued to detect cesium within milk, vegetation, and meat throughout the end of 2011.

These supplemental REMP environmental air, rain, vegetation, milk, meat, and sticky pad samples were obtained during 2011. These samples identified detectable concentrations of isotopes that could be related to operation of Diablo Canyon NPS. Given the following facts, the detectable isotopic concentrations are not a result of Diablo Canyon NPS operation:

0

1. The quantities of radioactive airborne effluents from Diablo Canyon NPS during 2011 did not increase significantly compared to year 2010.

2. Prior REMP sample results have not detected the presence of these isotopes at these concentrations over the last ten years of DCPP operation.

3. The isotopes detected correspond to timelines related to the Fukushima Prefecture Japan nuclear accidents and the jet stream deposition of those isotopes to the west coast of the United States.

4. The concentrations detected within the indicator samples were also identified in the normal REMP control samples and supplemental Fukushima event sampling far from Diablo Canyon NPS.

5. These isotopes were also detected by other Government Agencies, Nuclear Power Sites, and Colleges across the United States.

As such, the atypical detection of these radionuclides in both indicator and control samples is credibly attributed to the trans-Pacific transport of airborne releases from Dai-Ichi, Fukushima following the March 11, 2011 Tohoku earthquake and was not related to the operations of Diablo Canyon NPS. A summary of the sample results are provided in Appendix A, Appendix C, and Appendix D.

5.0 GROUND WATER MONITORING Diablo Canyon is committed to improving management of situations involving inadvertent radiological releases that get into onsite groundwater that is or may be used as a source of drinking water. This commitment reflects the nuclear industry's high standard of public radiation safety and protection of the environment. Trust and confidence on the part of local communities, States, the NRC, and the public is paramount to this commitment.

Studies of the DCPP ISFSI site and a general assessment of sub-regional hydro-geologic conditions indicates that groundwater (subsurface) flow beneath the Diablo Canyon power block site is west toward the Pacific Ocean or northwest toward Diablo Creek. It should be noted that Diablo Creek also discharges into the Pacific Ocean.

5.1 NEI 07-07 GROUNDWATER PROTECTION INITIATIVE VOLUNTARY REPORTING 5.1.1 NEI 07-07 Objective 2.4, Annual Reporting:

Document all on-site ground water sample results and a description of any significant on-site leaks/spills into ground water for each calendar year in the AREOR or the ARERR

DCPP Response to NEI 07-07 Objective 2.4 Onsite groundwater monitoring points are described in the REMP and reported in this Annual

Radiological Environmental Operating Report (AREOR) as follows:

- Observation Well 01 (OWl), Observation Well 02 (OW2), Drywell 115 (DY1), DCSF96-1 (8S3),

Water Well 02 (WW2), and Diablo Creek Outlet (WN2) were used for data reporting. A summary of the sample results are provided in Appendix A and Appendix C.

DCPP REMP sampled all available groundwater regardless of present or future use. The ground water beneath the DCPP protected area is not used as a source of drinking water.

There were no significant onsite leaks/spills into groundwater in 2011.

5Note: the term "significant" is defined by the NEI Initiative as an item or incident that is of Sinterest to the public or stakeholders. It does not imply or refer to regulatory terminology nor is it

intended to indicate that the leak or spill has public health and safety or environmental protection consequences. This term also has a volume component of greater than 100 gallons.

5.2 ADDITIONAL GROUNDWATER SAMPLING OVERVIEW:

o

Ground water monitoring was reported in accordance with the nuclear industry NEI 07-07 5Groundwater Protection Initiative and the REMP. Concentrations of tritium were detected in three monitoring wells beneath the DCPP power block. This tritium was coming from the rain-0washout of gaseous tritium exiting the plant vent system via an approved discharge route. DCPP has conducted rain-washout studies to document this phenomenon. These monitoring wells consisted of French drain systems that discharge into the associated monitoring well (OW 1, S

S S

S OW2, or DYl). Rain communicated with these French drain systems via building structure to ground interfaces. Once rain water entered the monitoring wells, the water remained stagnant until another rain event caused transport. Subsequent quarterly sampling routinely indicated correlated tritium values due to monitoring well stagnation. DY 1 routinely experienced the highest tritium rain washout concentrations due to its close proximity to the plant vent discharge points. It should be noted that hydro geological studies of the DCPP site indicate that any groundwater (subsurface) flow beneath DCPP would flow toward the Pacific Ocean.

The specific ranges of tritium detected in these monitoring wells for 2011 are as follows:

OW l - Observation Well 01 ( 401 to 710 pCi/L ) of 4 samples collected for tritium analysis.

OW2 - Observation Well 02 ( 1,140 to 1,340 pCi/L ) of 4 samples collected for tritium analysis.

DY1 - Drywell 115 ( 11,800 to 64,800 pCi/L ) of 7 samples collected for tritium analysis.

No other DCPP related isotopes were detected.

Monitoring Well 8S3 was sampled 4 times in 2011. Tritium was not detected in these 4 samples from 8S3. No other DCPP related isotopes were detected.

All other samples of groundwater at 1A2, WW2, and WN2 did not indicate the presence of tritium or any other DCPP related isotopes (only naturally occurring radionuclides were observed).

6.0 OLD STEAM GENERATOR STORAGE FACILITY MONITORING In accordance with the DCPP Offsite Dose Calculation Manual (ODCM), the Old Steam Generator Storage Facility (OSGSF) sumps were inspected quarterly. If water was found in the sump of a vault containing plant equipment, the expectation was to sample that sump water and dispose of the water per plant protocols via an approved discharge pathway.

For reference, the following equipment was placed into this OSGSF on the following dates:

3/2/08 (outage 2R14), four DCPP Unit Two (U-2) Steam Generators

2/14/09 (outage 1R15), four DCPP Unit One (U-I) Steam Generators

11/6/09 (outage 2R15), one DCPP Unit Two (U-2) Reactor (Rx) Head

& 10/23/10 (outage 1R16), one DCPP Unit One (U-l) Rx Head As of 12/31/11, the OSGSF contains eight old Steam Generators and two old Rx Heads.

S The OSGSF sumps were inspected quarterly by REMP personnel. During the first quarter of 2011, rainwater in-leakage was found within the U-I old Rx Head vault # 28 and U-2 Old Steam Generator vault # 30 sumps.

This sump water had tritium concentrations of 2,000 to 34,000 pCi/Liter due to diffusion of tritium from the stored equipment, into the OSGSF air, and subsequent diffusion from the air into the stagnant sump water. This tritium concentration phenomenon was communicated to the rest of the industry.

The rainwater from the sumps was removed and processed via an approved DCPP radwaste discharge pathway.

Construction repairs were made to the OSGSF to prevent rainwater from entering the OSGSF.

Specific repairs involved OSGSF vertical wall crack repairs and installation of roof gutters around the east and south side of the OSGSF. These repairs have been successful for prevention of rainwater intrusion into the OSGSF. These OSGSF sumps remained dry in 2011.

0 Laboratories LLC 0 P.O. Box 30712, Charleston, SC 29417 2011 ANNUAL QUALITY ASSURANCE REPORT Page 8 of 58 The Nuclear Procurement Issues Committee (NUPIC) audit was conducted on November 14, 2011 through November 18, 2011. This Duke Energy/NUPIC QA audit was performed for the activities and/or documentation/records associated with GEL Laboratories supplying general chemistry, radiochemistry and bioassay analytical services. This audit found that the GEL Laboratories quality system is well documented and/or implemented, and is acceptable.

With the exception of the six (6) audit findings, all of the requirements of GEL Laboratories Quality Assurance Plan audited were found to be satisfactorily implemented, and therefore, 0 "Continued approval of GEL Laboratories as an Appendix B supplier of general chemistry, radiochemistry and bioassay analytical services is recommended."

0 All responses to the six findings have been adequately addressed by GEL. The Audit Report #

22837-A for Supplier Number 5644 has been posted on the NUPIC website.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (i.e., MAPEP, and ERA/ELAP), GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.

5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of any one result from the known value. The second criterion concerns precision, which deals with the ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.

At GEL, we also evaluate our analytical performance on a regular basis through statistical 0 process control (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.

For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GEL's AlphaLIMS. We also measure precision with matrix duplicates and/or matrix spike duplicates.

The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences.

The static precision criteria for radiochemical analyses are 0 - 20%, for activity levels exceeding 0 the contract required detection limit (CRDL).

6. Quality Control Program for Environmental Sample Analysis GEL's internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response), blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control and qualification analyses samples are used to be as similar as 0

the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples, (or performance evaluation samples) are either actual sample submitted in duplicate in order to evaluate the precision of laboratory measurements, or fortified blank samples, which have been given a known quantity of a radioisotope that is in the interest

! to GEL's clients.

Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is 75 - 125%. Specific instructions for out-of-control situations are

provided in the applicable analytical SOP.

GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to

which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.

Some methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking 00water matrix.

Bias (%) = (observed concentration)

100 %

(known concentration)

Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves.

0Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.

GEL's laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is analyzed independently from the parent sample and the results are compared to measure 0precision and accuracy.

If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPD). The

RPD must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPD must be equal to or less than 100%. If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100% or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both

results are below MDC, then the limits on % RPD are not applicable.

Difference (%) = (high duplicate result - low duplicate result)

12. Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002.

A formal corrective action is initiated when a nonconformance reoccurs or is so significant that 0 permanent elimination or prevention of the problem is required.

0GEL includes quality requirements in most analytical standard operating procedures to ensure 9 that data are reported only if the quality control criteria are met or the quality control measures 0that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and

Identifying Opportunities for Improvement. Recording and documentation is performed

following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

0 Any employee at GEL can identify and report a nonconformance and request that corrective 0action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in

GL-QS-E-002. In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of

the discovery.
