Nuclear plants can now justify emergency plan reviews every two years, not annually

US nuclear regulators have updated their guidance for emergency response planning. This change allows nuclear power plant operators to justify reviewing their emergency plans every 24 months instead of every 12 months.

Nuclear power plant operators previously had to review their emergency plans every year. This new guidance means they can now argue for a less frequent, biennial review cycle. It also updates the list of acceptable guidance documents for meeting regulatory requirements, which could streamline compliance for some operators.
