Transforming the Uranium Fuel Cycle: Safe & Economical Conversion of DUF6 to DUF4 [Slides]
Project Outcomes: Designed and fabricated SS reaction vessels for executing reactions with UF6 at SIGMA, followed by transport and analysis at TA-48; Established a new capability at SIGMA for performing small mass transfers of UF6; Safety documentation approved for performing new UF6 chemistry at SIGMA; Staff training and conversion opportunity established for LANL Seaborg post-doc; Neat reaction with HMDS (CH3)3Si-Si(CH3)3 produced fluorosilanes; In reactions with solvents, fluorination observed. No DUF4 observed yet. Observations: Only 4 reactions were completed – more clearly needed; Due to problems with procurement, we did not get the mass control flow (MFC) unit until late August; Due to staff and time shortages UF4 was never delivered from SIGMA to TA-48 by SHIP-IT; Established ability for future collaboration between C and Sigma.
