Reactor Vessel Material Surveillance Program

The U.S. Nuclear Regulatory Commission (NRC) is confirming the effective date of February 1, 2021, for the direct final rule that was published in the Federal Register on October 2, 2020. The direct final rule amends the NRC's reactor vessel material surveillance program requirements for commercial light-water reactors. The direct final rule revises the requirements associated with the testing of specimens contained within surveillance capsules and reporting the surveillance test results. The direct final rule also clarifies the requirements for the design of surveillance programs and the capsule withdrawal schedules for surveillance capsules in reactor vessels purchased after 1982.
