A closer look at the initial NLIC selections—Part 2
In January, the Department of Energy announced its new Nuclear Lifecycle Innovation Campus (NLIC) program, inviting states via a request for information to express their interest in hosting a facility supporting work from the front to the back end of the nuclear fuel cycle.
By April, 26 states had expressed interest in hosting such a facility. At the end of July, the DOE signed memorandums of understanding with five states—Idaho, Louisiana, Oklahoma, Tennessee, and Utah—to more closely explore the possibilities of state-federal partnerships. These MOUs are not firm commitments from either the federal or state governments. Time will tell which—if any—of the five states develop projects through the program. In the meantime, today, we are taking a close look at what Utah, Idaho, Tennessee can offer in terms of a preexisting nuclear sector that could support new fuel cycle developments.

This technical note deals with simulation-based design optimization for the ex-core Transformational Challenge Reactor (TCR). Three-dimensional geometry was created for the TCR ex-core. Computational fluid dynamics (CFD) simulations were performed to optimize forced circulation airflow. The CFD model includes thermofluidic phenomena such as convective, conductive, and radiative heat transfer. The simulation results are presented for three different inlet coolant mass flow rates (2, 4, and 8 kg/s). The observed optimized flow rate for the base configuration was 5 kg/s. The calculated peak temperatures were within the safety limits for all components including the bio-shield (433 K) and the shroud mechanism (473 K).
