ssessment program to be provided to the NRC (1) during the CP or OL review for new nuclear reactor applications under 10 CFR Part 50, (2) during the review of DC applications under 10 CFR Part 52, (3) during the review of COL applications under 10 CFR Part 52, (4) during the review of EPU applications, or (5) before major plant modifications. The schedule needs to address the following considerations: a. For CP applications under 10 CFR Part 50, the reactor internals design needs to be classified in the preliminary safety analysis report (PSAR) as a prototype, limited DG-1323, Page 36 prototype or a non-prototype. Experimental or analytical justification of the non-prototype classification needs to be presented during the CP review under 10 CFR Part 50. For OL applications, the classification may be revised in the FSAR if schedule changes with respect to the previously designated reference reactor make such reclassification appropriate. For applications submitted under 10 CFR Part 52, the issues related to justification of the non-prototype classification need to be resolved during the review of the DC or COL application. If the justification is insufficient to meet the guidelines provided in this regulatory guide, the applicant will need to develop a test plan to obtain additional data as a prototype as discussed in this regulatory guide. The reactor internals design needs to be classified as a prototype, limited prototype or a non-prototype category in the application. If the internals are classified as non-prototype, the applicable prototype reactor internals need to be identified. b. During the staff’s review of the CP, OL, DC, or COL application, as appropriate, the scope of the CVAP needs to be established. c. The preoperational test procedures, power ascension program, and CVAP report need to be made available to the NRC in a timely manner for staff review and resolution of comments. d. The preliminary and final reports, which together summarize the results
