Second round of Launch Pad selections includes eight newcomers
The National Reactor Innovation Center at Idaho National Laboratory has announced 13 project selections across 12 companies for the Nuclear Energy Launch Pad, a Department of Energy–led program that integrates reactor and fuel facility authorization, testing, and deployment support for private nuclear developers.
The Launch Pad emerged from the Reactor Pilot Program and Fuel Line Pilot Program.
According to INL, projects selected include reactor development and nuclear fuel cycle advancements, including fabrication, enrichment, and conversion technologies.

The stability of Alfvén eigenmodes (AEs) driven by fast ions is investigated in the Experimental Advanced Superconducting Tokamak (EAST). It is demonstrated that all AEs found in toroidal AE gaps are stable and that the least stable mode is a reversed shear Alfvén eigenmode (RSAE) with . The calculation results show that collisional damping is the main damping mechanism for toroidal mode number . The excitation threshold for the RSAE is about βcrit,b = 3.33%, bigger than the value of the central beam ion beta βb = 1.01%. The results show that AEs driven by fast ions are stable in EAST, at least for the parameters shown in this work. The effect of beam ion pressure and energy on AE stability is also presented. The drive coming from fast ions increases with the pressure gradient, and the drive mainly comes from 3 resonance.
