Performance-Based Emergency Core Cooling Systems Cladding Acceptance Criteria
On March 24, 2014, the U.S. Nuclear Regulatory Commission (NRC) published for public comment a proposed rule revising the acceptance criteria for the emergency core cooling system (ECCS) for light-water nuclear power reactors. The NRC is also seeking public comment on three draft regulatory guides that would support the implementation of the proposed rule. The public comment period for the proposed rule and associated draft guidance was to have ended on June 9, 2014. The public comment period for information collection aspects of this rule was to have ended on April 23, 2014. Due to requests from members of the public, the NRC has extended the comment periods for the proposed rule, the associated draft guidance, and the information collection aspects until August 21, 2014.
