eferences a design certification rule. These items constitute information requirements but are not the only acceptable set of information in the FSAR. An applicant may depart from or omit these items, provided that the departure or omission is identified and justified in the FSAR. After issuance of a construction permit or COL, these items are not requirements for the license unless such items are restated in the FSAR. v. The investment protection short-term availability controls in section 16.3 of the DCD. E. Tier 2*- means the portion of the Tier 2 information, designated as such in the generic DCD, which is subject to the change process in the design certification rule. This designation expires for some Tier 2* information at fuel load. The DCDs for the evolutionary designs consisted of an introduction, Tier 2 information, which is mostly the standard safety analysis report (SSAR) for the standard design), and Tier 1 information. The significance of designating design information as either Tier 1 or Tier 2 is that different change processes and criteria apply to each tier, as described in the evolutionary design certification rules. Basically, Tier 1 information is difficult to change after the design certification rule is issued because changes require a finding by the NRC that the change is needed to assure adequate protection of the public health and safety. This results in a very high threshold for change to Tier 1 by either the NRC or others once the rule is issued. Whereas, Tier 2 information can be changed by a combined license (COL) applicant or licensee under a "50.59-like" process, provided the change does not impact Tier 1. The entire change process is set forth in the design certification rules (Appendices A - D to 10 CFR Part 52). The remainder of this appendix discusses the form and content of the DCD, selected issues unique to design certification reviews, and additional guidance for DCDs. This guidance relies on the requirements for design
