​GAIN provides the nuclear energy industry with access to the technical, regulatory, and financial support necessary to move new or advanced nuclear reactor technologies toward commercialization, as well as ensuring the continued safe, reliable, and economic operation of the existing nuclear reactor fleet. GAIN offers a single point of access to the broad range of capabilities across DOE's national laboratory complex. DOE has invested billions of dollars to build and maintain expertise and infrastructure within the national laboratory system. This vast capability should be leveraged effectively to support commercialization of new advanced nuclear reactor designs.

Focused research opportunities and dedicated industry engagement are important components of GAIN to ensure that DOE-sponsored activities support technology companies that are working to realize the full potential of nuclear energy.

Assistance for reactor technology developers in navigating through the regulatory process is another highly important element of GAIN. In collaboration with the Nuclear Regulatory Commission (NRC), DOE will work through GAIN with prospective applicants for advanced nuclear technologies to understand and navigate the regulatory process for licensing advanced technology.

GAIN integrates and facilitates efforts by private industry, universities and government research institutions to test, develop and demonstrate advanced nuclear technologies to accelerate the licensing and commercialization of these systems.
