Steady-state results

The temperature and cross flow in the bypass are shown in Figure 1 and Figure 2. The power extracted by the flow in the bypass is about 2MW, and the maximum outlet temperature in the bypass is about 1370K. Figure 2 shows the flow redistribution at the core inlet because of the different flow resistance between the subchannels. Figure 3 shows the resulting temperatures in the moderator and fuel.

Run Commands

This simulation is run using Pronghorn by running the command below. The Subchannel submodule of Pronghorn must be compiled with Pronghorn to run this input.
