Steve,

This email and the attached file respond to the questions and request by NuScale during the 9/26/2018 teleconference between the NRC staff and NuScale regarding the NRC staffs review of NuScale initial test program. If you have any questions, please let me know.

Thanks, Omid Begin Forwarded Message:

Hi Omid,

During our call with NuScale on 9/26/18 to discuss review options related to the ITP, NuScale requested that the staff provide a listing of the test abstracts that were discussed in Option 3. The attached document provides the requested information along with the description of the three options. In addition, NuScale asked whether the staff planned on reviewing the front matter of Section 14.2 (up to the test abstracts) and the COL items. The answer is yes that staff would be reviewing the COL Items and Section 14.2 front matter.

It is our recommendation that the email to them and the attached document be put into ADAMS. Please let us know if NuScale has any further questions.

Thanks

Option 1: Cease Review of the NuScale Initial Test Program (ITP)

There is no regulatory requirement for an ITP for a design certification. The Combined License (COL) applicant would be responsible to submit an ITP that would meet the revised staff guidance. No additional resources would be needed.

Option 2: Review of the Safety Significant System Functions Finality would be limited to a test existing (listed beneath the abstracts) for each of the risk significant system functions identified in the design reliability assurance program (D-RAP), but not on the test abstracts. The COL applicant would be responsible for a program that would meet the revised staff guidance, i.e., test abstracts that test the entire system. Approximate resources needed to complete Phase 2 by internal deadline on October 31st: 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />.

The regulations in 10 CFR 50.43(e) also apply to DC and COL applications licensed under 10 CFR 52.47(a)(2)(iii), 10 CFR 52.47(c)(2) and 10 CFR 52.79(a)(28). In practice, the DC applicant would provide design and test acceptance criteria for its portion of the design while the COL applicant would provide design and test acceptance criteria for the site-specific design features (e.g., ultimate heat sink). The COL would then put into place plans for preoperational, initial criticality, low-power, and power ascension tests under the ITP.

The DSRS also states:

The applicant should provide test abstracts of SSCs and unique design features that will be tested to verify that system and component performance is in accordance with the design. These test abstracts should include the objectives, tests, and acceptance criteria that will be included in the test procedures.

Finality could be provided for the test abstracts identified below (the list may change). However, for test abstracts that are not reviewed by the staff, finality cannot be provided. The focus would

be on test abstracts containing A1, A2, and B1 systems, as well as ITAAC and FOAK testing.

The COL applicant would still be responsible for providing appropriate procedures. Resources needed to complete Phase 2 by estimated internal deadline of December 21st (subject to change): at least 600 hours0.00694 days <br />0.167 hours <br />9.920635e-4 weeks <br />2.283e-4 months <br />.
