layout the first, second and third intercooler pressure drops were set to 30, 40 and 50 kPa, respectively. These pressure drops were chosen because they are representative of pressure drops used in the MIT studied on an indirect Helium Brayton cycle with a maximum system pressure of 8 MPa [Wang, 2003]. A base design for each cycle was determined and input into HYSYS. HYSYS was then used to simulate and optimize each cycle. The base cycle used in this study was the indirect Helium cycle and the operating conditions used are summarized in Table 5. The efficiency without intercooling was 45.19%. The efficiency with 1,2 and 3 intercoolers was 48.25%, 48.92% and 49.07%, respectively.

For these calculations, a cycle similar to the proposed Advanced High Temperature (AHTR) (Forsberg et al., 2004, Peterson, 2002) was used with Flibe, a fluoride molten salt, as a coolant fluid in the primary side and helium in the Brayton cycle. Theoretically a combination of reheat and intercooling increases the cycle efficiency in a closed cycle, the implications have not been explored. Multiple-reheat is technically viable for closed gas cycles, as demonstrated by the PBMR turbomachinary design with three separate turbines. For gas-cooled reactors, a multiple reheat option may not be practical due to higher-pressure loss associated with gases, i.e., helium, supercritical CO2, and nitrogen. However, molten coolants can transport heat with low pumping power requirement, which becomes very attractive without any consideration of material problems associated with molten coolants at high temperatures. Figure 15 shows the layout of the HYSYS simulation. In the primary side, stream 1 to 6 has Flibe as a coolant and in the secondary side, streams 7 through 21 has helium as a working fluid. The cycle efficiency from this simulation is 56%, which is much higher 16PDF Image | Development of a Supercritical Carbon Dioxide Brayton Cycle: Improving PBR Efficiency and Testing Material Compatibility
