Contained in this document are guidelines that should be followed when preparing Criticality
Safety Evaluations that will be used to demonstrate the safety of operations performed at
Department of Energy (DOE) Non-Reactor Nuclear Facilities. Adherence with these guidelines
will provide consistency and uniformity in Criticality Safety Evaluations (CSEs) across the
complex and will document compliance with the requirements of DOE Orders 420.1, Section 4.3,
and 5480.24 that pertain to CSEs as given in the following documents.
Validation of Calculational Method
Single Parameter Limits for Fissile Nuclides
- Process Evaluation For Nuclear
- Double Contingency
7.c (First Paragraph) -
"... contractors shall perform detailed nuclear criticality safety
analyses for specific operations, storage arrangements, and the
handling and transportation of fissionable material."
- General Requirements
- Application of DOE-STD-3007-93
These guidelines become effective 180 days after issuance by DOE-HQ. Rewriting existing
evaluations solely to comply with these guidelines is not required.
In accordance with Section 3.2 of ANS-8.1-1983, the word "shall" is used in these guidelines to
denote a requirement, the word "should" to denote a recommendation, and the word "may" to
