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.
Supplier Showcase
January 27, 2026|1:00–2:00PM (2:00–3:00PM EST)
Available to All Users
Join ANS and Curtiss-Wright for a Supplier Showcase webinar featuring a deep dive into the digital technologies transforming power uprate projects. We’ll highlight Data Validation & Reconciliation (DVR)—a technology approved for MUR uprates—and demonstrate how it improves data accuracy and supports uprate justification. We’ll also explore best practices for using PEPSE, the industry-standard plant modeling and simulation software, to perform power uprate studies and assess plant performance impacts. This webinar will provide practical insights, case-style examples, and actionable approaches for applying these tools in real uprate projects.
