The NRC published the draft guidance document in the Federal Register on July 21, 2014 (79 FR 42224). The NRC received seven comments on the draft guidance. The NRC's response to the public comments received can be found in the fourth section of the final guidance. The guidance document is for use by applicants, licensees, Agreement States, and the NRC staff. This guidance document (ADAMS Accession No. ML18176A377) has four parts: the first two are revisions to existing information in the NUREG-1556, “Consolidated Guidance About Materials Licenses,” series of volumes for medical uses (Volume 9) and commercial nuclear pharmacies (Volume 13); the third part is a series of questions and answers to assist applicants and licensees in understanding and implementing the new regulatory changes; and the fourth is the comments received on the proposed guidance during the public comment period, and the NRC's responses. The current NUREG-1556 documents provide guidance to applicants for the completion and submission of materials license applications to the NRC. The documents also include model procedures that an applicant may consider when developing its radiation safety program.
