r developing information related to SSC design requirements and capabilities, including DBHLs, special treatment requirements, and system descriptions for SR SSCs with the following clarifications and additions: a. Clarification and additional information: In addition to describing the DBHLs as stated in NEI 21-07, Revision 1, Section C.6, on SAR Chapter 6, the application should also include the translation of DBHLs to loads on SSCs, evaluation of those loads, and related design analyses. NEI 21-07, Revision 1, does not provide guidance in this area; applicants can refer to Section C.I.3 of RG 1.206, Revision 0 (Ref. 42) for guidance.11 For an advanced non-LWR application, this material may be included in Chapter 2 of the SAR or in reports submitted separately from but incorporated by reference in the SAR.
