Supreme Court nixes Beyond Nuclear’s CISF challenge
The U.S. Supreme Court has denied a petition by antinuclear group Beyond Nuclear challenging the Nuclear Regulatory Commission’s licensing of Holtec International’s proposed consolidated interim storage facility (CISF) for spent nuclear fuel in New Mexico.
The denial of Beyond Nuclear’s writ of certiorari petition was part of a long list of orders released by the Supreme Court on Monday. The list also included a denial of Duke Energy’s appeal of a lower court’s ruling in an antimonopoly dispute.
