FPoliSolutions demonstrates RISE, an RIPB systems engineering tool
The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) has held another presentation in its monthly Community of Practice (CoP) series. Former RP3C chair N. Prasad Kadambi opened the October 3 meeting with brief introductory remarks about the RP3C and the need for new approaches to nuclear design that go beyond conventional and deterministic methods. He then welcomed this month’s speakers: Mike Mankosa, a project engineer at FPoliSolutions, and Cesare Frepoli, the company’s president, who together presented “Introduction to RISE: A Digital Framework for Maintaining a Risk-Informed Safety Case for Current and Next Generation Nuclear Power Plants.”

This paper illustrates numerical simulations of heat transfer and fluid flow in triangular section and unit cell section of fuel blocks of High Temperature Gas-cooled Reactor (HTGR). The thermal hydraulic simulations have been performed in a minimalistic computational resource environment and their viabilities have been studied. General Atomics Modular High Temperature Gas-cooled Reactor (MHTGR) has been considered in this work as a reference design. In this paper, 3-D models of triangular section and unit cell section of fuel blocks similar to the MHTGR design have been developed for single phase helium flow using COMSOL Multiphysics software. In these models, velocity profiles, temperature profiles, pressure profiles, Reynolds number profiles and Nusselt number profiles have been studied. Algebraic y+ turbulence model has been used in this work. Finally, the simulation results have been compared with General Atomics provided MHTGR design parameters and theoretically obtained results to check for their accuracy and viability.
