Radioisotope and Analytical Chemistry Lab
BWXT has been providing comprehensive chemical and radiochemical monitoring, sampling, and analytical services for over 40 years.
Founded in the early '60s as a research facility, the Radioisotope and Analytical Chemistry Laboratory (RACL) has become a key provider of specialty services associated with commercial and government decommissioning and site remediation efforts. Our laboratories operate under NRC licenses and EPA permits. These qualifications allow RACL to receive virtually all types and quantities of radioactive materials. RACL is a DOECAP qualified supplier to the U.S. Department of Energy and has successfully completed a nuclear utility audit of RACL's compliance with Nuclear Utilities Procurement Issues Committee (NUPIC) requirements. RACL is also National Environmental Laboratory Accreditation Program (NELAP) accredited by Virginia Division of Consolidated Laboratory Services (VELAP ID #460127) and the Utah Department of Health (ELCP ID# BWNU).
The radiochemistry laboratory performs analyses on a wide range of matrices, such as soil, water, decommissioning debris, waste, and mixed waste samples. The laboratory also has secure facilities to accommodate classified samples (DOE-CRD). Radiochemical analyses are performed for alpha, beta, gamma, and X-ray emitting isotopes. Examples of recent projects include characterization of: Battelle Columbus TRU waste, Savannah River Site tank waste, and TRU-bearing filter media from Los Alamos National Laboratory.
ANALYTICAL CHEMISTRY LABORATORY
The analytical chemistry laboratory offers a variety of techniques to characterize radioactive inorganic materials. These techniques include quantitation of elemental species by Inductively Coupled Plasma/Mass Spectroscopy, mercury analysis by Cold Vapor Atomic Absorption, Ion Chromatography for the analysis of samples, and X-ray Diffraction to identify crystalline phases in compounds.
