Start Preamble

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.
