Appendix 1
APPLICATION OF THE GRADED APPROACH IN ORR PLANNING
For the purposes of this appendix, the graded approach is defined as the process by which the
readiness determination is adjusted in depth of detail required and magnitude of resources expended to
be commensurate with the facility's potential impact on safety, environmental compliance, safeguards
and security, and its programmatic importance, including present and future mission. The graded
approach will be commensurate with:
(1) The relative importance to safety, safeguards, and security;
(2) The magnitude of any hazard involved;
(3) The life cycle stage of a facility;
(4) The programmatic mission of a facility;
(5) The particular characteristics of a facility;
(6) The cause and circumstances of the facility shutdown; and
(7) Other relevant factors.
All ORRs will address the minimum set of core requirements and any additional requirements as
deemed necessary for adequate review (breadth). A recent review, equivalent to an ORR, may be used
as justification for eliminating a core requirement from the breadth of the ORR. With respect to ORR
planning, a graded approach is utilized to determine the level of detail, that is, the depth. The
combination of breadth and depth forms the envelope (scope) within which the ORR is conducted.
Proper utilization of the graded approach is essential to conducting a successful ORR. The supporting
principle governing the use of the graded approach must be that knowledgeable personnel analyze the
factors surrounding the restart, determine the depth of the review needed, and then document this
determination. Precise documentation will facilitate communication with knowledgeable outside
officials that the proper level of review has been conducted and that readiness to operate has been
accurately verified.
The depth of an ORR cannot be determined using a cookbook or formula approach. Depth
requirements depend on knowledgeable people identifying relevant topics based on their experience,
the facility's characteristics, the facility's operating environment, the operating and support
organizations' capabilities, and the risks associated with the proposed startup or restart. An aid that
