lt verification) for the NRC staff to make a safety determination using the relevant requirements and guidance; b. related interface requirements; and c. possible system interactions. Where sufficient information is available to limit or avoid the need for DAC, DC applicants should include this design information in their applications. The following chapters and sections of the SRP present additional information on technical and regulatory acceptance criteria for the subjects identified above: a. SRP Section 3.6.2, “Determination of Rupture Locations and Dynamic Effects Associated with the Postulated Rupture of Piping”; Section 3.6.3, “Leak-Before-Break Evaluation Procedures”; and Section 3.12 address piping. b. SRP Chapter 7, “Instrumentation and Controls,” addresses I&C. c. SRP Chapter 12, “Radiation Protection,” addresses radiation protection. d. SRP Chapter 14, “Initial Test Program and ITAAC-Design Certification,” includes ITAAC and Tier 1 information relevant to all DAC. e. SRP Chapter 18, “Human Factors Engineering,” addresses HFE. Combined License Applications A COL applicant referencing a DC with DAC should understand that the path to successfully resolving DAC issues and completing the associated ITAAC may include the NRC staff’s inspection of information or procedures that are prepared early in the construction, fabrication, or development processes. These inspections require NRC inspectors to become involved early in such processes (e.g., safety system software development). For this reason, it is crucial that a COL applicant using DAC provide the NRC staff with timely access to detailed design information to resolve potential issues. In addition, COL applicants whose applications reference a DC with DAC may find, when completing the analysis associated with the DAC, that changes are needed to the plant design or other licensing documents (e.g., generic and plant-specific technical specifications), some of which may require
