SUMMARY
OF JUNE 7, 2023, PARTIALLY CLOSED COMPUTATIONAL FLUID DYNAMICS TOPICAL REPORT PRE-SUBMITTAL MEETING WITH FRAMATOME INC. AND THE U.S.
NUCLEAR REGULATORY COMMISSION (EPID L-2023-NTR-0003)
On June 7, 2023, the U.S. Nuclear Regulatory Commission (NRC) staff held a partially closed meeting via Microsoft Teams with representatives from Framatome Inc. (Framatome). The purpose of the meeting was for the NRC staff and Framatome representatives to hold pre-submittal discussions on Framatomes planned single phase computational fluid dynamics (CFD) topical report (TR). The topics discussed include the TR content, intended applications, Verification and Validation (V&V) process, Phenomena Identification and Ranking Table (PIRT) assessment, methodology validations, and uncertainty quantification. The meeting notice is available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML23157A329.
During the open session, the Framatome representative explained the meetings objective, submittal schedule, intended applications, and provided an overview of the TR content. There were no NRC staff questions and no members of the public in attendance.
During the closed session, the NRC staff and Framatome representatives discussed single-phase CFD methodology designated commercial code, the virtual experimental platform, typical CFD pressure field results and models, and applicability. In addition, the Framatome representative also explained anticipated classes of problems, V&V process, PIRT assessment, methodology Validation, and the pressure loss coefficient methodology predictive performance associated with the single-phase CFD methodology. The Framatome representatives addressed the NRC staffs questions regarding code verification and its review challenges, V&V, code calculation/solution verification, and validation data during the closed session.
