Presenter: Mark-18A Target Material Recovery Program: Initial Hot Startup

Savannah River National Laboratory

Bio

Kathryn Taylor-Pashow is a Scientist at Savannah River National Laboratory (SRNL). She holds a Ph.D. in Inorganic Chemistry from the University of North Carolina at Chapel Hill. Her current research at SRNL focuses on high level waste treatment, nuclear materials processing, and separation technologies.

Taylor-Pashow’s Thursday morning presentation will cover SRNL’s task to recover highly valued isotopes from irradiated Mark-18A (Mk-18A) targets. The targets were manufactured with Pu-242 then irradiated under high neutron flux in K-Reactor at SRS from 1968 to 1978. The targets will be individually transported to SRNL for processing. Upon receipt at SRNL, the Mk-18A target material will be removed from the confinement, dissolved, chemically separated, and calcined to a stable oxide. The flowsheet is designed to recover the plutonium as well as the trivalent actinides. This presentation will discuss the operating experience, lessons learned, and results from initial hot startup.
