Regulatory guide; withdrawal.
The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide (RG) 3.29, “Preheat and Interpass Temperature Control for the Welding of Low-Alloy Steel for Use in Fuel Reprocessing Plants and in Plutonium Processing and Fuel Fabrication Plants.” This guide is being withdrawn because the guidance can be found in RG 1.50, Rev. 1, “Control of Preheat Temperature for Welding of Low-Alloy Steel.”
Please refer to Docket ID NRC–2014–0070 when contacting the NRC about the availability of information regarding this document. You may access publicly-available information related to this action by the following methods:

The NRC is withdrawing Regulatory Guide (RG) 3.29, “Preheat and Interpass Temperature Control for the Welding of Low-Alloy Steel for Use in Fuel Reprocessing Plants and in Plutonium Processing and Fuel Fabrication Plants,” which was published in May 1975 (ADAMS Accession No. ML003739381). RG 3.29 provides guidance on methods acceptable to the NRC for meeting quality assurance (QA) requirements with regard to controlling the welding of low-alloy steel components for fuel reprocessing plants and for plutonium processing and fuel fabrication facilities.
The withdrawal of RG 3.29 does not alter any prior or existing licensing commitments based on its use. Regulatory guides may be withdrawn when their guidance no longer provides useful information, or is superseded by technological innovations, Congressional actions, or other events.
Regulatory guides are revised for a variety of reasons and the withdrawal of a regulatory guide should be thought of as the final revision of the guide. Although a regulatory guide is withdrawn, current licensees may continue to use it, and withdrawal does not affect any existing licenses or agreements. Withdrawal of a guide means that the guide should not be used for future NRC licensing activities. Changes to existing licenses can be accomplished using other regulatory products.
