Performance-Based Emergency Core Cooling Systems Cladding
Acceptance Criteria
AGENCY: Nuclear Regulatory Commission.
ACTION: Proposed rule; extension of comment period.
-----------------------------------------------------------------------
SUMMARY: 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proposed rule and associated draft guidance was to have ended on June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proposed rule, the associated draft guidance, and the information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.
DATES: The comment periods for the proposed rule, the associated draft
guidance, and the information collection aspects (79 FR 16106; March
24, 2014) have been extended and now end on August 21, 2014.

II. Discussion
On March 24, 2014, the NRC published a proposed rule revising the
acceptance criteria for the ECCS for light-water nuclear power reactors
(79 FR 16106). The proposed ECCS acceptance criteria are performance-
based, and reflect recent research findings that identified new
embrittlement mechanisms for fuel rods with zirconium alloy cladding
under loss-of-coolant accident conditions. The proposed rule also
addresses two petitions for rulemaking by establishing requirements
applicable to all fuel types and cladding materials, and requiring the
consideration of crud, oxide deposits, and hydrogen content in
zirconium-based alloy fuel cladding. Further, the proposed rule
contains a provision that would allow licensees to use an alternative
risk-informed approach to evaluate the effects of debris for long-term
cooling. 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draft guidance was to have ended on June 9, 2014.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.
Dated at Rockville, Maryland, this 16th day of April 2014.
For the Nuclear Regulatory Commission.

Secretary of the Commission.
