Abstract

This NUREG is written to provide guidance on the implementation of additional regulatory requirements for licensees authorized under Title 10 of the Code of Federal Regulations (10 CFR), Part 40 (Part 40), “Domestic Licensing of Source Material,” to possess threshold quantities of uranium hexafluoride (UF6). The document primarily provides guidance on the implementation of integrated safety analysis (ISA) requirements and also addresses updates to the emergency plan criteria, and reporting requirements among others. These requirements were implemented in the Part 40 rulemaking, dated [ENTER FEDERAL REGISTER DATE FOR PUBLICATION OF FINAL RULE FOR PART 40]. The guidance consists of references to the applicable portions of existing ISA guidance in NUREG-1513, “Integrated Safety Analysis Guidance Document,” issued May 2001 and NUREG-1520, Revision 1, “Standard Review Plan for the Review of a License Application for a Fuel Cycle Facility,” issued May 2010, which were written to support the implementation of ISA requirements in 10 CFR Part 70 (Part 70), “Domestic Licensing of Special Nuclear Material.”

The Commission directed the staff to implement the Part 40 ISA requirements in the Staff Requirements Memorandum to SECY-07-0146, “Regulatory Options for Licensing New Uranium Conversion and Depleted Uranium Deconversion Facilities,” dated October 10, 2007. The requirements are designed to better address the potential radiological and chemical hazards resulting from UF6 and hydrogen fluoride at certain source material facilities.

The ISA requirements are incorporated into Part 40, Subpart H, “Additional Requirements for Certain Licensees Authorized to Possess 2000 Kilograms (4400 lbs) or More of Uranium Hexafluoride,” and parallel the majority of ISA requirements in the existing Part 70, Subpart H, “Additional Requirements for Certain Licensees Authorized To Possess a Critical Mass of Special Nuclear Material.” The chief difference between the Part 40 and Part 70 ISA regulations is the absence of criticality requirements in the Part 40 ISA provisions. Due to the similarities in the ISA requirements between Part 40 and Part 70, portions of NUREG-1513 and NUREG-1520 apply to the Part 40 ISA. The guidance which is not applicable to Part 40, e.g., criticality, are noted and explained.
