Download as PDF TKELLEY on DSK3SPTVN1PROD with NOTICES 21812 Federal Register / Vol. 79, No. 74 / Thursday, April 17, 2014 / Notices not explicitly addressed by the Code design curves. The existing fatigue strain-vs.-life data illustrate potentially significant effects of light water reactor coolant environments on the fatigue resistance of pressure vessel and piping steels. Under certain environmental and loading conditions, fatigue lives in water relative to those in air can be significantly lower for austenitic stainless, nickel alloy, carbon and lowalloy steels. In March 2007, Revision 0 of NUREG/CR–6909 (ADAMS Accession No. ML070660620) was issued and it was the technical basis document for NRC Regulatory Guide 1.207, ‘‘Guidelines for Evaluating Fatigue Analyses Incorporating the Life Reduction of Metal Components Due to the Effects of the Light-Water Reactor Environment for New Reactors.’’ Revision 0 of NUREG/CR–6909 summarized the work performed at Argonne National Laboratory on the fatigue of piping and pressure vessel steels in light water reactor coolant environments. In that document, the existing laboratory fatigue data were evaluated to identify the various materials, environmental, and loading parameters that influence fatigue crack initiation, and document the effects of key parameters on the fatigue lives of pressure vessel and piping steels. The report presented fatigue life models for estimating fatigue lives as a function of material, loading, and environmental conditions, and described the environmental fatigue correction factor for incorporating the effects of light water reactor coolant environments into Code fatigue evaluations. Revision 1 of NUREG/CR–6909 provides updates and improvements to the environmental fatigue correction factor approach based on an extensive update to the laboratory fatigue data from testing and results available since 2007. The NRC is particularly interested in stakeholder feedback on the following three areas: i. The extension of the best-fit mean air curve for ferritic steels discussed in Section 3.1.10. ii. The air fatigue design curve adjustment factors summarized in Section 5.5. iii. Accuracy check of the technical content of the NUREG, particularly with respect to all of the numerical content of the report. Dated at Rockville, Maryland, this 9th day of April, 2014.

range of regulatory matters. This may include communicating staff 
technical positions on matters that have not been communicated to or
