The goals of this review process was to evaluate the guidance content, determine if the guidance conforms to current operational and technical circumstances, determine if the guidance meets the standards for classification under section 1.4 of E.O. 13526, and assess the likelihood of damage under section 1.2 of E.O. 13526. The review, which took over 2 years, has resulted in recommendations that will streamline, clarify, and enhance DOE NSI classification guidance.
