PERFORMANCE OF WIPP CERTIFIABLE MOBILE WASTE CHARACTERIZATION NDA MEASUREMENTS ON TRU WASTE DRUMS AT LLNL

BNFL Instruments Inc., formerly Pajarito Scientific Corp., has successfully performed WIPP certifiable mobile non-destructive assay (NDA) measurements at Lawrence Livermore National Laboratories, LLNL. The NDA system used to perform these measurements is a combined Imaging Passive/Active Neutron and Gamma Energy Analysis (IPAN/GEA) system. The measurements meet the requirements of WIPP’s Transuranic Waste Characterization Quality Assurance Program Plan (QAPP), CAO-94-1010. This work is one of only two ongoing privately contracted mobile waste characterization projects within the DOE complex. This paper describes the WIPP certification efforts, the CAO accepted measurement technique, and summarizes the measurement results.
