The U.S. Nuclear Regulatory Commission (NRC) has issued a new Regulatory Guide (RG) 3.78, titled "Acceptable ASME Section XI Inservice Inspection Code Cases", which offers guidance for the inservice inspection of spent fuel storage systems. It includes methods the NRC deems acceptable for compliance with its regulations regarding the inspection of confinement boundary components and aging management activities. The guide endorses specific codes and standards for certain licensees and holders to ensure safety and efficiency in nuclear storage practices. It does not mandate compliance but provides a reliable framework for industry participants.
Simple Explanation
The NRC made a new rulebook that shows safe ways to check the health of special gas storage boxes at nuclear sites, helping them stay safe without saying they must follow it.
