Several antinuclear groups are challenging the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ (ISP) consolidated interim storage facility for spent nuclear fuel in Andrews, Texas, by filing briefs in the U.S. Court of Appeals for the District of Columbia Circuit on March 18. The groups appealing the license include Beyond Nuclear, Don’t Waste Michigan (a coalition of seven environmental groups), and Sierra Club.

The NRC granted ISP a license in September 2021, authorizing the company to receive, possess, transfer, and store up to 5,000 metric tons of spent fuel and 231.3 metric tons of greater-than-Class C radioactive waste for 40 years. ISP plans to expand the facility in seven additional phases, up to a total capacity of 40,000 metric tons of fuel.
