Abstract [en]

The High Pressure Boiling Water Reactor (HP-BWR), based on operating experience with conventional BWRs and PWRs, avoids various problematic components of the traditional reactor design. The HP-BWR design relies on proven components such as the pressure vessel and the control rod drive systems from the PWR, and the core internals, circulation pumps, and steam-moisture separators from the BWR. Internal circulation pumps are used in the HP-BWR to assure hydrodynamic stability and the orifices at the fuel channel inlets are chosen so that the one phase pressure drop dominates over the two-phase pressure drop, avoiding hydrodynamic oscillations. The improved thermal efficiency is achieved by feeding the turbine with 618K steam, while the HP-BWR efficiency would increase to approximately 37% compared with 33% for the conventional BWRs.
