Title 10 of the Code of Federal Regulations Part 830, Nuclear Safety Management, Subpart B, Safety Basis Requirements, establishes safety basis requirements for hazard category 1, 2, or 3 DOE nuclear facilities. This Standard provides an acceptable methodology to “[c]ategorize the facility consistent with DOE-STD-1027-92 (“Hazard Categorization and Accident Analysis Techniques for compliance with DOE Order 5480.23, Nuclear Safety Analysis Reports,” Change Notice 1, September 1997),” as required by 10 CFR Section 202(b)(3). 4. The goal of this revised Standard is to maintain consistency with the methodology of DOE- STD-1027-92, CN1, while providing clearer criteria and guidance to support effective and consistent hazard categorization based upon more recent input values and lessons learned in implementing DOE-STD-1027-92, CN1.
