IMPLEMENTATION The purpose of this section is to provide information to applicants and licensees regarding the NRC’s plans for using this draft regulatory guide. The NRC does not intend or approve any imposition or backfit in connection with its issuance. The NRC has issued this draft guide to encourage public participation in its development. The NRC will consider all public comments received in development of the final guidance document. In some cases, applicants or licensees may propose an alternative or use a previously established acceptable alternative method for complying with specified portions of the NRC’s regulations. Otherwise, the methods described in this guide will be used in evaluating compliance with the applicable regulations for license applications, license amendment applications, and amendment requests. REGULATORY ANALYSIS Statement of the Problem The NRC initially issued Regulatory Guide 1.34, “Control of Electroslag Weld Properties,” in December 1972. The guidance does not reflect changes in the ASME Boiler and Pressure Vessel Code since 1972. Therefore, revision of this regulatory guidance is necessary to reflect updates in the ASME Code. Objective The objective of this regulatory action is to update the NRC’s guidance for the control of electroslag weld properties, consistent with changes in the ASME Code since December 1972.
