Nuclear and Facility Safety Orders


The Office of Nuclear and Facility Safety Policy is the Office of Primary Interest (OPI) responsible for the development, interpretation, and revision of the following DOE Orders. Go to our Directives Web Page to view these Orders.


DOE-Order (O)-252.1,Department of Energy Technical Standards Program
The Technical Standards Program (TSP) promotes the use of voluntary consensus standards by the Department of Energy (DOE), provides DOE with the means to develop needed technical standards, and manages overall technical standards information, activities, issues, and interactions. The technical standards documents defined and managed by the TSP include DOE Standards, Handbooks, Specifications, and Technical Standards Lists, as outlined in DOE-G-252.1-1, TECHNICAL STANDARDS PROGRAM GUIDE, and the Technical Standards Program Procedures (TSPPs).
