Advanced nuclear reactor manufacturers-fuel storage.

Wyoming's SF 186 establishes rules for storing spent nuclear fuel used in reactors manufactured and deployed within the state. It requires advanced nuclear reactor manufacturers (companies operating in Wyoming) to use temporary dry cask storage (special containers designed for safe storage), submit detailed applications to the state environmental department, and provide binding timeframes for moving fuel to permanent storage or reprocessing. The bill mandates reporting to state and local emergency authorities, exempts these facilities from other siting laws, and allows fees to be charged if fuel remains stored beyond agreed timelines. This directly affects Wyoming-based reactor manufacturers and their fuel storage operations, with no broader public impact specified.
