Omar Hurricane: Scientific proof of principle at the NIF

January 14, 2022, 7:00AMNuclear News

Hurricane

In 2012, Omar Hurricane, a distinguished member of the technical staff at Lawrence Livermore National Laboratory, was asked by the laboratory director to lead a team to delve into studying the physics and engineering obstacles preventing fusion ignition at the National Ignition Facility (NIF). The team’s efforts led to a new exploratory “basecamp” strategy and the creation of several pivotal experiments that revealed some of the underlying problems with the ignition point design, while also delivering improved fusion performance and the first evidence of significant alpha particle self-heating.

Hurricane was appointed chief scientist of the Inertial Confinement Fusion Program in 2014, a position he has held ever since. He was named a Fellow of the American Physical Society’s Division of Plasma Physics in 2016 and was recently awarded the Edward Teller Medal from the American Nuclear Society for his work on inertial confinement fusion physics.

Nuclear thermal propulsion (NTP) is one technology that could propel a spacecraft to Mars and back, using thermal energy from a reactor to heat an onboard hydrogen propellant. While NTP is not a new concept, fuels and reactor concepts that can withstand the extremely high temperatures and corrosive conditions experienced in the engine during spaceflight are being designed now.

BWX Technologies announced on December 13 that it has delivered coated reactor fuels to NASA for testing in support of the Space Technology Mission Directorate’s NTP project. BWXT is developing two fuel forms that could support a reactor ground demonstration by the late 2020s, as well as a third, more advanced and energy-dense fuel for potential future evaluation. BWXT has produced a videoof workers processing fuel kernels in a glovebox.
