. The applicant may choose to provide design processes and design acceptance criteria (DAC) for this material, as discussed in Appendix A to SRP Section 14.3. The rationale for determining which areas of the design should utilize design processes and acceptance criteria should be documented by the applicant in DCD Tier 2 Section 14.3. Essentially, the applicant should extract the most important design processes and acceptance criteria from Chapter 12 of Tier 2 and put them into Tier 1. This may be done in a separate section of Tier 1, or provided in the applicable systems of Tier 1. A COL applicant or licensee must meet these criteria in the design of the plant, and the staff can audit the facility's design documentation to ensure that the criteria are met. The following discussion is specific to the review of design processes and acceptance criteria in this area: Applicants may not provide the complete design information in this design area before design certification because the radiation shielding design and the calculated concentrations of airborne radioactive material were dependent upon as-built and as-procured information of plant systems and components. Therefore, applicants may not be able to describe the standard design's radiation source terms (i.e., the quantity and concentration of radioactive materials contained in, or leaking from plant systems) in sufficient detail to allow the staff to verify the adequacy of the shielding design, ventilation system designs, or the design and placement of the airborne radioactivity monitors. Instead, applicants may provide the processes and acceptance criteria by which the details of the design in this area would be developed, designed, and evaluated. This scope of the material in Tier 1 should be stated in the design description. Examples of its application could be to the radiological shielding and ventilation design of the reactor building, turbine building, control building, service building, and radwaste
