  • 5.4 LABORATORY EQUIPMENT QUALITY ASSURANCE
  • 5.4.1 DAILY QUALITY CONTROL
  • EnRad Laboratories has an internal quality assurance program which monitors
  • each type of instrumentation for reliability and accuracy. Daily quality control checks ensure that instruments are in proper working order and these checks are
  • used to monitor instrument performance.

0 5.4.2 CALIBRATION VERIFICATION National Institute of Standards and Technology (NIST) standards that represent 0counting geometries are analyzed as unknowns at various frequencies ranging

  • from weekly to annually to verify that efficiency calibrations are valid. The frequency is dependent upon instrument use and performance. Investigations are performed and documented should calibration verification data fall out of limits.

5.4.3 BATCH PROCESSING 0

  • Method quality control samples are analyzed with sample analyses that are processed in batches. These include gross beta in drinking water and all tritium
  • analyses.

5.5 DUKE ENERGY INTERCOMPARISON PROGRAM EnRad Laboratories participated in the Duke Energy Nuclear Generation Department 0 Intercomparison Program during 2011. Interlaboratory cross-check standards, including Marinelli beakers, air filters, air cartridges, gross beta in water, and tritium in water samples were analyzed at various times of the year. A summary of the EnRad Laboratory program results for 2011 is documented in Table 5.0-A.

5.6 ECKERT & ZIEGLER ANALYTICS CROSS CHECK PROGRAM EnRad Laboratories participated in the Eckert & Ziegler Analytics Cross Check Program during 2011. Cross-check standards including, Marinelli beakers, air filters, tritium in water, and Iodine in milk samples were analyzed at various times of the year.

A summary of the EnRad Laboratory program results for 2011 is documented in Table 5.0-B.

5.7 ERA PROFICIENCY TESTING EnRad Laboratories performed method proficiency testing through a program administered by Environmental Resource Associates (ERA) of Arvada, CO. ERA supplied requested method proficiency samples for analysis and nuclide concentration determination. ERA reported proficiency test results to the North Carolina Department of Health and Human Services, North Carolina Public Health Drinking Water Laboratory Certification Program. A summary of these proficiency test data for 2011 is documented in Table 5.0-C.

5.8 DUKE ENERGY AUDITS 0 The McGuire Nuclear Station Radiological Environmental Monitoring Program was not audited by the Quality Assurance Group in 2011, but was audited in 2010. Procedure and report enhancements were identified as part of this audit (reference 6.12).

0 5.9 U.S. NUCLEAR REGULATORY COMMISSION INSPECTIONS 5 S

The McGuire Nuclear Station Radiological Environmental Monitoring Program was audited by the NRC in 2011 (reference 6.14). There were no REMP findings identified by the 2011 audit.

S 5.10 STATE OF NORTH CAROLINA INTERCOMPARISON PROGRAM EnRad Laboratories routinely participates with the State of North Carolina Department of Environmental Health and Natural Resources (DEHNR) in an intercomparison program. EnRad Laboratories sends air, surface water, milk, crops, vegetation, sediment, and fish samples which have been collected to the State of North Carolina Radiation Protection Section.

ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of all environmental media at McGuire Nuclear Station was required to ensure compliance with Station Selected Licensee Commitments. Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.

Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, and Fisheries and Aquatic Ecology.

This appendix describes the environmental sampling frequencies and analysis procedures by media type.

S I. CHANGE OF SAMPLING PROCEDURES TLD Location 191 (Special Interest) description updated (reference 6.19).

0 H. DESCRIPTION OF ANALYSIS PROCEDURES Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software. Designated sample volumes are transferred to appropriate counting geometries and analyzed by gamma spectroscopy. Perishable samples such as fish and broadleaf vegetation are ground to achieve a homogeneous mixture. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.) then transferred to appropriate counting geometry.

0 Low-level iodine analyses are performed by passing a designated sample aliquot through a pre-weighed amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried, mixed thoroughly, and a net resin weight determined before being transferred to appropriate counting geometry and analyzed by gamma spectroscopy.

Tritium analyses are performed quarterly by using low-level environmental liquid scintillation analysis technique on a Packard 2550 liquid scintillation system or Perkin-Elmer 2900TR liquid scintillation system. Tritium samples are distilled and batch processed with a tritium spike and blank to verify instrument performance and sample preparation technique are acceptable.

Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate 0 and analyzing by Tennelec XLB Series 5 gas-flow proportional counters. Samples are batch processed with a blank to ensure sample contamination has not occurred.

0 S Ill. CHANGE OF ANALYSIS PROCEDURES 0 No analysis procedures were changed during 2011.

S IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE 0 Airborne particulate and radioiodine samples at each of seven locations were 0 composited continuously by means of continuous air samplers. Air particulates were 0 collected on a particulate filter and radioiodines were collected in a charcoal cartridge positioned behind the filter in the sampler. The samplers are designed to operate at a constant flow rate (in order to compensate for any filter loading) and are set to sample 0 approximately 2 cubic feet per minute. Filters and cartridges were collected weekly.

A separate weekly gamma analysis was performed on each charcoal cartridge and air 0 particulate. A weekly gioss beta analysis was performed on each filter. The S continuous composite samples were collected from the locations listed below.

  • An inner ring of 14 TLDs at the site boundary, one in each available meteorological sector. The site boundary locations in the N and NNW sectors are over water; however, two special interest TLD's were placed in these sectors inside the site boundary in March, 1991.'

  • An annual Land Use Census was conducted to identify within a distance of 8
  • kilometers (5.0 miles) from the station, the nearest location from the site boundary in
  • each of the sixteen meteorological sectors, the following:
  • The Nearest Residence
  • The Nearest Garden greater than 50 square meters or 500 square feet
  • The Nearest Milk-giving Animal (cow, goat, etc.)
  • The census was conducted during the growing season on 5/20/2011. Results are
  • shown in Table 3.10. No changes were made to the sampling procedures during 2011
  • as a result of the 2011 census.

In the environmental program, the air deposition parameters (D/Q) are used to 0determine air, broadleaf vegetation and milk sampling locations. McGuire's sectors

  • with the three highest values did not change in 2011.

GLOBAL POSITIONING SYSTEM (GPS) ANALYSIS S The McGuire site centerline used for GPS measurements was referenced from the S McGuire Nuclear Station Updated Final Safety Analysis Report (UFSAR), section 2.1.1, S Site Location. Waypoint coordinates used for MNS GPS measurements were latitude S 35°-25'-59"N and longitude 80'-56'-55"W. Maps and tables were generated using North American Datum (NAD) 27. Data normally reflect accuracy to within 2 to 5 meters S from point of measurement. GPS field measurements were taken as close as possible to S the item of interest. Distances for the locations are displayed using three significant S figures.
