    摘要： The present relates to the integration of the primary functional elements of graphite moderator and reactor vessel and/or primary heat exchangers and/or control rods into an integral molten salt nuclear reactor (IMSR). Once the design life of the IMSR is reached, for example, in the range of 3 to 10 years, it is disconnected, removed and replaced as a unit. The spent IMSR functions as the medium or long term storage of the radioactive graphite and/or heat exchangers and/or control rods and/or fuel salt contained in the vessel of the IMSR. The present also relates to a nuclear reactor that has a buffer salt surrounding the nuclear vessel. During normal operation of the nuclear reactor, the nuclear reactor operates at a temperature that is lower than the melting point of the buffer salt and the buffer salt acts as a thermal insulator. Upon loss of external cooling, the temperature of the nuclear reactor increases and melts the buffer salt, which can then transfer heat from the nuclear core to a cooled containment vessel.

    摘要： A machine, article, process of using, process of making, products produced thereby and necessary intermediates. Illustratively, there can be a process of producing electrical power, the process comprising: creating neutrons via nuclear reactions, said neutrons carrying neutron kinetic energy; moderating said neutrons to thermal energies to produce moderated neutrons, converting the neutron kinetic energy into heat, and transmitting said heat to a heat exchanger; creating ions via the nuclear reactions, stopping the ions to produce heat, and transmitting to said heat exchanger the heat generated by the stopping of the ions; capturing said moderated neutrons with sulfur atoms to produce heat, and transmitting to said heat exchanger energy released by the capturing of said moderated neutrons; transmitting energy from decaying radioisotopes created by the capturing of said moderated neutrons to said heat exchanger; heat exchanging at least some of each said heat and energy in said heat exchanger by converting water into steam; and generating electrical power with said steam.

    摘要： In a pressurized water reactor (PWR), emergency core cooling (ECC) responds to depressurization due to a vessel penetration break at the top of the pressure vessel by draining water from a body of water through an injection line into the pressure vessel. A barrier operates concurrently with the ECC to suppress flow of liquid water from the pressure vessel out the vessel penetration break. The barrier may comprise one or more of: (1) an injection line extension passing through the central riser to drain water into the central riser; (2) openings in a lower portion of a central riser to shunt some upward flow from the central riser into a lower portion of the downcomer annulus; and (3) a surge line providing fluid communication between a pressurizer volume at the top of the pressure vessel and the remainder of the pressure vessel which directs water outboard toward the downcomer annulus.
