8.0 SUMMARY & CONCLUSIONS
The overall criticality safety assessment of the system being analyzed should be summarized in this
section. The range of applicability and special limitations in the evaluation should be stated.
A statement about the application of Double Contingency should also be provided. (e.g., "As
indicated in Section 6.0, this operation adheres to the Double Contingency Principle;" or "as
discussed in Section 6.0, this system will remain subcritical under all credible upset conditions.")
If unique requirements must be satisfied (those discussed in Section 3.0), a statement of
compliance with these requirements should be given.
When applicable, reference to normal and abnormal ranges of operational parameters may also be
made. Portions of the evaluation that have been deferred to other efforts or documents should be
To the extent practical, a criticality safety evaluation should stand on its own. However,
references may be used liberally so all external technical information (information from handbooks
or information from other reports that is beyond the scope of the evaluation) and relevant
descriptive information can easily be verified. Private communications, as references, should be
avoided, and crucial conclusions of the evaluation shall not depend on private communications.
MATERIALS & COMPOSITIONS
All materials used in computations should be identified and atom densities should be given. When
applicable, nuclide library IDs should be included. All other information, such as assumed bulk or
theoretical densities, that is required to duplicate the atom densities used in the evaluation should
also be given. This information may be incorporated by reference.
TYPICAL INPUT LISTINGS
Typical input listings for all major perturbations in modeling should be included in this appendix.
If cross section preprocessing is performed, typical input listings for all cross section codes (e.g.,
NITAWL, BONAMI, XSDRNPM, COMBINE/PC) that are used in the evaluation should also be
included. This information may be incorporated by reference.
