摘要:
Systems and methods for providing a molten salt reactor are described. While the systems can include any suitable component, in some cases, they include a graphite reactor core that defines an internal space, with multiple fuel wedges being received in the internal space, and with the wedges each defining a fuel channel extending from a first end to a second end of each of the wedges. In some cases, the reactor further includes a fuel pin rod that defines an internal fuel conduit and that is disposed between at least two of the wedges. In some cases, the reactor core defines a fuel ingress port and a fuel egress port. In some such cases, the reactor core is rotatably received within a reactor housing such that the ports are configured to become at least one of more occluded and less occluded as the reactor core rotates. Other implementations are described.

A system of generating electricity is disclosed. The system employs a new kind of swimming pool type nuclear reactor which is safe and can be made operable unattended but at the same time raises the mean pool temperature by forcing moderator-coolant-shield circulation. When the reactor is combined with an organic Rankine cycle engine, a significant improvement in efficiency of electricity generation can be obtained, making very small nuclear/electricity units economically viable.
摘要:
A low pressure water reactor (LPWR) and a method for controlling a LPWR; the LPWR comprises a reactor vessel with an internal cavity comprising a primary coolant, a riser tube, and a core located below ground level with 6-15 bars atmosphere pressure; a steam drum connected to the riser tube at ground level at a pressure of 1-10 bars absolute; a water storage tank to store borated water; a passive injection system injecting the borated water from the water storage tank into the vessel; and low pressure steam turbines generating power at 1-10 bars atmosphere. The vessel heats water up to temperature and the riser tube converts the heated water to steam, delivered to the turbine(s). The conversion creates a difference in a primary coolant density that initiates a density-driven natural circulation of the primary coolant in the riser tube, downcomer, steam drum and core.
