Information on Licensing Applications for Fracture Toughness 
Requirements for Ferritic Reactor Coolant Pressure Boundary Components

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory issue summary; issuance.


SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing 
Regulatory Issue Summary (RIS) 2014-11, ``Information on Licensing 
Applications for Fracture Toughness Requirements for Ferritic Reactor 
Coolant Pressure Boundary Components.'' This RIS provides guidance to 
applicants for, and holders of, nuclear power reactor licenses, 
construction permits, standard design approvals, and manufacturing 
licenses, and applicants for standard design certifications, on the 
scope and detail of information that should be provided in licensing 
applications regarding reactor vessel fracture toughness and associated 
pressure-temperature limits. The RIS explains that these entities 
should ensure that pressure-temperature limits developed in accordance 
with NRC requirements sufficiently address all ferritic materials of 
the reactor vessel, including the impact of structural discontinuities 
and neutron fluence accumulation.

DATES: The RIS is available as of November 10, 2014.

    The NRC published a notice of opportunity for public comment on 
this RIS in the Federal Register on April 17, 2014 (79 FR 21812). The 
agency received comments from two commenters. The staff considered all 
comments, which resulted in minor changes to the RIS. The evaluation of 
these comments and the resulting changes to the RIS are discussed in a
