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 study evaluates heat transfer characteristics of a sub-channels-inserted (SCI) porous heat removal device for divertor cooling. It is clarified that increasing the total volume of the sub-channels strongly contributes to the enhancement of phase-change of coolant as well as the vapor discharge. A high heat flux of approximately 25 MW/m2 is removed at a wall superheat less than 70 K by increasing the number of the sub-channels installed under low flow rate conditions. The results also suggest that the SCI porous heat removal device could be applicable for the divertor cooling by optimizing the sub-channel design. Furthermore, especially for an enlarged heating area, optimizing the location of the sub-channel inlet, that is the interval of each sub-channel inlet, could be essential in order to smoothly discharge the generated vapor outside the porous medium.
