Gateway for Accelerated Innovation in Nuclear
About GAIN
We are a U.S. Department of Energy initiative built to provide access to government support that moves innovative nuclear energy technologies — for both advanced reactors and the existing nuclear fleet — toward commercialization to assist and educate those new to nuclear on its benefits, applications and role in our clean future energy transition.
Industry Support
GAIN provides the nuclear community with access to the technical, regulatory, and financial support necessary to move innovative nuclear energy technologies toward commercialization while ensuring the continued safe, reliable, and economic operation of the existing nuclear fleet.
Our Work
In addition to supporting the commercialization of advanced nuclear technologies, GAIN works with organizations (states, utilities, communities) that are new to nuclear and interested in learning more.
Resources
GAIN has compiled a list of key legacy databases, directories..(need wording)
