NPSI Project Manager, Scientist
Walter Luscher
(509) 375-6828

Dr. Luscher, a Materials Scientist, joined PNNL in 2007 to support activities within the Nuclear Engineering & Analysis group of the Signature Sciences and Technology Division in the National Security Directorate. These activities include reviewing licensing and topical report reviews for the U.S. Nuclear Regulatory Commission (NRC) as well updating, maintaining, and distributing the FRAPCON/FRAPTRAN fuel performance codes on behalf of the NRC. These codes model the thermomechanical response of fuel rods under steady-state and transient conditions, respectively. Dr. Luscher also supports the Tritium Sustainment Program as the Irradiation and Materials Testing Task Manager. In this role, he develops and oversees the execution of both in- and ex-reactor experiments that are tailored to meet specific information needs of the program. In-reactor testing activities have primarily focused on a series of separate effects tests known as the TMIST experiments. These instrumented lead experiments have permitted the influence of irradiation on zirconium oxidation and hydrogen permeation through stainless steel to be evaluated under specified conditions. An in-reactor experiment is currently underway to evaluate the kinetics and speciation of tritium released from 6Li-enriched LiAlO2 pellets during irradiation. Dr. Luscher is an active member of the Nuclear Materials Committee for The Minerals, Metals, and Materials Society (TMS) and a member of the American Nuclear Society (ANS) and American Ceramic Society (ACerS).
