Content:
repair for wrought low-alloy and high-alloy steels , nickel-base alloys, or other materials (such as static and centrifugal castings and bimetallic joints) should comply with the fabrication standards specified in Sections III and IX of the ASME Code, supplemented by the following: (1) Performance qualification should provide for testing the welder under simulated position, access, and visibility limitations when any of these physical conditions restrict the welder’s access to a production weld to less than 30 centimeters (12 inches) in any direction from the joint, or when visibility of the weld pool is limited or the welder must assume an awkward position. (2) Requalification should be necessary when (a) position, access, and visibility conditions for production welding are significantly more limiting than the physical conditions present during qualification, or (b) any of the essential welding variables listed in Section IX change. (3) Production welding and adherence to welding qualification criteria should be monitored. D. IMPLEMENTATION The purpose of this section is to provide information to applicants and licensees regarding the NRC staff’s plans for using this draft regulatory guide. No backfitting is intended or approved in connection with its issuance. The NRC has issued this draft guide to encourage public participation in its development. Except in those cases in which an applicant or licensee proposes or has previously established an acceptable alternative method for complying with specified portions of the NRC’s regulations, the methods to be described in the active guide will reflect public comments and will be used in evaluating (1) submittals in connection with applications for construction permits, standard plant design certifications, operating licenses, early site permits, and combined licenses; and (2) submittals from operating reactor licensees who voluntarily propose to initiate system modifications if there is a clear nexus between the
