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.

This technical note describes the ongoing development of a double stub Fast Ferrite Tuner (FFT) for the Alcator C-Mod 4.6 GHz Lower Hybrid Current Drive (LHCD) system. This FFT uses an electromagnet coil and permanent magnet on each tuning stub. The FFT is required to withstand over 200 kW of power (20 KW/cm2) for several second pulses spaced 10 minutes apart. The FFT will be computer controlled and must react to matching a load in a few hundred microseconds. We will present measurement of the system along with simulations. Breakdown measurements, operational achievements and computer control algorithm will be shown.
This program has also revealed the inaccuracy in simulation of the models in leading finite element codes such as CST and COMSOL. We have been able to insert a model for Ion Cyclotron Range of Frequency (ICRF) work into COMSOL but unable to do this for Lower Hybrid at this time.
