Reactor Vessel Material Surveillance Program

The U.S. Nuclear Regulatory Commission (NRC) is publishing a regulatory basis to support a rulemaking that would amend the NRC's regulations for the light-water power reactor vessel material surveillance programs. The rulemaking would reduce the regulatory burden associated with the testing of specimens contained within surveillance capsules, and reporting the surveillance test results. The NRC has completed a regulatory basis that demonstrates there is sufficient justification to proceed with rulemaking. The NRC is providing the basis for rulemaking for public information, but is not seeking public comment on the regulatory basis at this time.
