Federal Register / Vol. 86, No. 124 / Thursday, July 1, 2021 / Proposed Rules specific technical specifications after the issuance of a license that references this appendix and the change process.
After a license is issued, the bases for the plant-specific technical specification would be controlled by the bases change provision set forth in the administrative controls section of the plant-specific technical specifications.
I. RESERVED Section IX
This section is reserved for future use.
The matters discussed in this section of earlier design certification rules inspections, tests, analyses, and acceptance criteriaare now addressed in the substantive provisions of 10 CFR
part 52. Accordingly, there is no need to repeat these regulatory provisions in the NuScale design certification rule.
However, this section is being reserved to maintain consistent section numbering with other design certification rules.

J. Records and Reporting Section X
The purpose of Section X of appendix G to 10 CFR part 52 is to set forth the requirements that will apply to maintaining records of changes to and departures from the generic DCD, which are to be reflected in the plant-specific DCD. Section X also sets forth the requirements for submitting reports including updates to the plant-specific DCD to the NRC. This section of appendix G to 10 CFR part 52 is similar to the requirements for records and reports in 10 CFR part 50, except for minor differences in information collection and reporting requirements.
Paragraph X.A.1 requires that a generic DCD including referenced SUNSI and SGI be maintained by the applicant for this proposed rule. The generic DCD concept was developed, in part, to meet the requirements for incorporation by reference, including public availability of documents incorporated by reference. However, the SUNSI and SGI could not be included in the generic DCD because they are not publicly available. Nonetheless, the SUNSI and SGI were reviewed by the NRC and, as stated in paragraph VI.B.2, the NRC would consider the information to be resolved within the meaning of 52.63a5. Because this information, or its equivalent, is not in the generic DCD, it is required to be provided by an applicant for a license referencing this design certification rule.
Only the generic DCD is identified and incorporated by reference into this rule.
The generic DCD and the NRC approved version of the SUNSI and SGI must be maintained by the applicant NuScale Power for the period of time that

appendix G to 10 CFR part 52 may be referenced.
Paragraphs X.A.2 and X.A.3 place recordkeeping requirements on the applicant or licensee that reference this design certification so that its plantspecific DCD accurately reflects both generic changes to the generic DCD and plant-specific departures made under Section VIII. The term plant-specific is used in paragraph X.A.2 and other sections of appendix G to 10 CFR part 52 to distinguish between the generic DCD that would be incorporated by reference into appendix G to 10 CFR
part 52, and the plant-specific DCD that the COL applicant is required to submit under paragraph IV.A. The requirement to maintain changes to the generic DCD
is explicitly stated to ensure that these changes are not only reflected in the generic DCD, which will be maintained by the applicant for the design certification, but also in the plantspecific DCD. Therefore, records of generic changes to the DCD will be required to be maintained by both entities to ensure that both entities have up-to-date DCDs.
Paragraph X.A.4.a requires the design certification rule applicant to maintain a copy of the aircraft impact assessment analysis for the term of the certification and any renewal. This provision, which is consistent with 50.150c3, would facilitate any NRC inspections of the assessment that the NRC decides to conduct. Similarly, paragraph X.A.4.b requires an applicant or licensee who references appendix G to 10 CFR part 52
to maintain a copy of the aircraft impact assessment performed to comply with the requirements of 50.150a throughout the pendency of the application and for the term of the license and any renewal. This provision is consistent with 50.150c4. For all applicants and licensees, the supporting documentation retained should describe the methodology used in performing the assessment, including the identification of potential design features and functional capabilities to show that the acceptance criteria in 50.150a1 will be met.
Paragraph X.A does not place recordkeeping requirements on site specific information that is outside the scope of this rule. As discussed in paragraph V.B of this document, the final safety analysis report required by 52.79 will contain the plant-specific DCD and the site-specific information for a facility that references this rule.
The phrase site specific portion of the final safety analysis report in paragraph X.B.3.c refers to the information that is contained in the final safety analysis report for a facility

required by 52.79, but is not part of the plant-specific DCD required by paragraph IV.A. Therefore, this proposed rule does not require that duplicate documentation be maintained by an applicant or licensee that references this rule because the plantspecific DCD is part of the final safety analysis report for the facility.
Paragraph X.B.1 requires applicants or licensees that reference this rule to submit reports that describe departures from the DCD and include a summary of the written evaluations. The requirement for the written evaluations is set forth in paragraph X.A.3. The frequency of the report submittals is set forth in paragraph X.B.3. The requirement for submitting a summary of the evaluations will be similar to the requirement in 50.59d2.
Paragraph X.B.2 requires applicants or licensees that reference this rule to submit updates to the DCD, which include both generic changes and plantspecific departures, as set forth in paragraph X.B.3. The requirements in paragraph X.B.3 for submitting reports will vary according to certain time periods during a facilitys lifetime. If a potential applicant for a COL that references this rule decides to depart from the generic DCD prior to submission of the application, then paragraph X.B.3.a will require that the updated DCD be submitted as part of the initial application for a license. Under paragraph X.B.3.b, the applicant may submit any subsequent updates to its plant-specific DCD along with its amendments to the application provided that the submittals are made at least once per year.
Paragraph X.B.3.b also requires semiannual submission of the reports required by paragraphs X.B.1 and X.B.2
throughout the period of application review and construction. The NRC will use the information in the reports to support planning for the NRCs inspection and oversight during this phase, when the licensee is conducting detailed design, procurement of components and equipment, construction, and preoperational testing.
In addition, the NRC will use the information in making its finding on ITAAC under 52.103g, as well as any finding on interim operation under Section 189.a1Biii of the Atomic Energy Act of 1954, as amended. Once a facility begins operation for a COL
under 10 CFR part 52, after the Commission has made a finding under 52.103g, the frequency of reporting will be governed by the requirements in paragraph X.B.3.c.
