Na-HPMR Multiphysics Results

Multiphysics analysis was completed in the 1/6 core HP-MR model for the steady state operation of the Na-HPMR by coupling the Griffin high-fidelity neutronics with CFEM-SN(1,3) neutronics solver, the BISON heat conduction model, and the Sockeye heat-pipe performance model. In this section, the simulation results are discussed.

Steady State Results

Figure 1: Steady state operation conditions as predicted by the Na-HPMR multiphysics model.

At the nominal power of ~2.07 MW, the Griffin-BISON-Sockeye model predicts the steady state operating conditions shown in Figure 1 with key parameters summarized in Table 1
