摘要：【課題】超ウラン元素(TRU)を燃焼させる原子炉を提供する。【解決手段】TRUを急速に燃焼(爆発)させるために爆縮という手段がある。本発明では爆発に重点を置かずに、比較的急速に燃焼させ続けるということに重点を置いた。特に、TRUは自発中性子を多量に放出するから、臨界未満でも核分裂が非常に活発であり、燃焼が比較的長時間続く。時間が経過すると爆縮の効果がなくなるため核分裂反応は低下する。臨界超過であれば、爆縮の効果が残っている短時間の間に核分裂反応が急激に高まり、TRUが急激に燃焼消滅する。【選択図】図1

摘要： PURPOSE:To attain a small sized and simpler nuclear power generation device, by converting heat generated in a reactor core directly to electricity utilizing a thermoelectric conversion element. CONSTITUTION:A high temperature coolant 14 heated in a reactor core flows inside of thermoelectric conversion element 11 fixed to an inner wall of a pressure shell 10 and heats the element 11. A low temperature coolant 14 after heat exchanging with the element 11 returns to the reactor core 1 through a circulating flow pass 12 and circulates after reheated in the core 1. Thereby the inner side of the elements is always kept at an elevated temperature by the heated coolant 14 and the outer side is kept at a lower temperature cooled by sea water 15, and consequently a direct current electromotive force is generated at the element 11. In this way, an electric power can be taken directly from the heat generated in the core 11 utilizing the element 11 and thereby simplification of the structure and a small sized and light weighed structure can be attained.

摘要： PURPOSE:To make it possible to prevent the leakage of a harmful substance component to any direction by a mechanism wherein two or more of an intermediate heat exchanger is provided between the titled extracting portion and the water producing apparatus as well as the heat medium pressure flowing therebetween is raised to the maximum degree within the titled heat transporting system. CONSTITUTION:The steam s from a turbo-steam extractor 1 of an atomic power plant is flowed into the first intermediate heat exchanger 2b and returned to a condencer of a power plant while the heat is supplied to a heat medium h circulating within an arranged pipe 2c. The heat of the above described heat medium h is supplied to a relatively low pressure heat medium h circulating within an arranged pipe system 2e in the second intermediate heat exchanger 2d. This heat is supplied to sea water o in a brine heater 3a of a water producing apparatus 3 and the heat treasport from an extracting portion 1 to an apparatus 3. Therefor, if the heat exchanger 2b, 2d are normally operated, the leakage from an apparatus to a power plant side is completely prevented even if a heater 3a is damaged. Moreover, even if both heat exchangers are damaged, the radioactive substance which may be contained within an arranged pipe system 2a is not leaked because the medium pressure within an arranged pipe system 2c is high. At the same time, Cl within sea water is not leaked to a power plant side.

摘要： PROBLEM TO BE SOLVED: To provide a nuclear power plant wherein a thermoelectric converter for directly generating electricity is installed instead of a conventional steam generator installed in a reactor container. SOLUTION: This nuclear power plant is provided with a reactor pressure vessel for accommodating a reactor core and a primary coolant; a heat exchanger for transferring the heat of the primary coolant to a second coolant; and a connecting pipeline for connecting the reactor pressure vessel to the heat exchanger to allow the flow of the primary coolant. The thermoelectric converter comprising a thermoelectric generator having passages for the first coolant and second coolant to adjacently flow on the high temperature side and low temperature side of a thermoelectric element module, and generating power on the basis of the temperature difference is installed in the heat exchanger. Structural members for a large number of heat transfer pipes, a generator turbine and a generator heretofore required, and a building for enclosing them are thereby dispensed with to provide the nuclear power plant that can improve economic performance, simplify a system, facilitate maintenance and improve the operating rate and safety of the power plant.
