for design certifications (DC), standard design approvals (SDs), manufacturing licenses (ML), and combined licenses (COL) submitted under 10 CFR Part 52. For OL applications under 10 CFR Part 50, the applicant must describe the initial test program (ITP) in the FSAR in accordance with 10 CFR 50.34(b)(6)(iii). For COL applications under 10 CFR Part 52, the applicant must describe the ITP, in accordance with 10 CFR 52.79(a)(28). For SD and DC applications, the applicants should submit proposed testing activities for the ITP. The COL applicant is responsible for identifying the remaining portions of the site-specific ITP tests and all of the applicable tests for each ITP test phase. Sections A-1 through A-5 of this appendix address the specific tests required for each of the five phases of the ITP, including (1) Preoperational Testing, (2) Initial Fuel Loading and Pre-Criticality Testing, (3) Initial Criticality, (4) Low-Power Testing, and (5) Power-Ascension Testing . In addition, Sections A-6 and A-7 contain guidance for implementing first-of-a-kind testing and design qualification tests for advanced reactors. No particular significance should be attached to the order in which the tests are listed. However, in general, those listed in Section 1, “Preoperational Testing” should precede those listed in Section 2, “Initial fuel loading and Pre-Critical Testing” and so on. The regulations in 10 CFR Parts 50 and 52 require that DC, SD, COL, ML, and OL applications identify certain design qualification tests for new reactor designs that are used to mitigate accidents or severe transients during the ITP testing period. A-1. Preoperational Testing For new plants licensed under10 CFR Part 52, the ITAAC incorporated into the COL comprises a set of preapproved verifications that licensees must meet before fuel load. In many cases, the ITAAC testing requirements are the same or similar to the preoperational tests required to be completed as part of the ITP.
