designs are important for one simple reason: they are being built.
While we are disappointed with DOE's decision to exclude Holtec from the award, we remain confident that our
reactor, the SMR - 160, has the greatest potential to triumph in a global marketplace because it is
designed to meet the highest expectations of safety and is uniquely engineered to compete economically with
other sources of alternative energy in the evolving era of cheap fossil fuels.

design reactors that control the plasma far more than
other fusion power devices.
The «Integral and Separate Effects Test Program for the Investigation and Validation of Passive Safety System Performance of SMRs» project would yield a uniquely configurable set of testing platforms to demonstrate passive safety system performance, accelerate the SMR - 160 and
