logies of interest. Reviews should verify 18.0-12 Revision 3 – December 2016 the methodology described is valid for the application in which it is used. The maturity of the design should dictate the reviewer’s emphasis on methodology versus final design. Mature, complete designs typically call for a general review of the methodology and a detailed review of the design (using NUREG-0700). The evaluator may adjust the priority given to the method and the final HFE design reviews based on application specifics. c. Design Certifications: Under a limited number of special conditions, the NRC accepts a detailed description of an HFE design process in lieu of a final design product. These conditions are identified in SECY-92-053, and are listed below: • rapidly changing technology could cause the approved design to be obsolete prior to construction, • as-built information (e.g., specific measurements) needed to complete the design is unavailable, • as-procured information needed to complete the design is unavailable. If an applicant proposes using this option, the staff will verify that at least one of these three conditions exists by reviewing the basis for the applicant’s proposal and that the proposal is limited to the only those elements to which the condition applies. When DAC is applied, the HFE design process for the applicable element is submitted as an implementation plan. The reviewer evaluates this implementation plan against the acceptance criteria for the associated NUREG-0711 element. Reviewers should note that this review not only verifies method validity but also ensures the process is sufficiently detailed and measurable that there is reasonable assurance that the process will result in a safe design product. The implementation plan also establishes specific acceptance criteria for an ITAAC if it is decided that an ITAAC is needed. d. In addition to safety-related HSIs, the HFE reviews should include non-safety- related HSIs for the following
