Gallego and Risch submit ARC Act 2.0 in the Senate
Sens. Jim Risch (R., Idaho) and Ruben Gallego (D., Ariz.) reintroduced the Accelerating Reliable Capacity (ARC) Act in the Senate on February 10.
According to the Department of Energy, it could take up to 10 deployments for a reactor design to become a mature commercial reactor. Getting from the first-of-a-kind (FOAK) to full commercial deployment is challenging, and the risks of higher costs and longer deployment timelines for early nuclear projects create significant uncertainty for investors. The ARC Act is designed to reduce that early deployment risk.
