摘要： PURPOSE:To decrease neutron irradiation dose to a nuclear reactor vessel and to improve reliability thereof by arranging a reflector at an inside of the nuclear reactor vessel and by making the reflector elevate in the nuclear reactor vessel. CONSTITUTION:A reflector 47 is arranged at an inner circumferential side of a nuclear reactor vessel. The reflector 47 faces to a lower end of reactor core 28 at operation start and the reactor core 28 is started its fuel burning from a lower end part of the reactor core. After that, the reflector 47 is gradually elevated up along a driving mechanism 48 by a driving motor 50 and therewith upper side reactor core fuel burns in sequence. Leaking neutrons when the core 28 burns the most fiercely, are reflected by the reflector 47 and therewith an extent of irradiation to the nuclear reactor vessel is much mitigated.

摘要： PURPOSE:To remove decay heat caused by natural ventilation cooling by conducting heat generated in a reactor container to an intermediate heat exchanger container and constituting an annulus space where the outside air passes the outside of the reactor container and heat exchanger container. CONSTITUTION:The nuclear reactor container is divided into plural parts 9a, 9b, and 9c and annulus spaces 13a, 13b, and 13c where outside air passes are formed outside of said container. Consequently, decay heat at the stop of a nuclear reactor is removed from the respective divided nuclear reactor containers by natural ventilation cooling. Further, the nuclear reactor container is reduced in size, so the safety of the nuclear reactor is improved more.

摘要： PURPOSE:To decrease a floor space and driving power load and to reduce the capacity of waste treatment equipment as well by carrying out and storing spent fuel in a spent fuel storage tank which does not require a system for cleaning pooled water and simplifying procedures for cleaning as well. CONSTITUTION:Equipment 23 for putting in an out of fuel including a fuel transferring machine 19 and a pantagraph arm 27 is provided in order to insert the fuel into a reactor core 2 and take the fuel out of the core. A fuel cleaning tank 24 in a fuel cleaning chamber 29, the spent fuel treatment equipment 25 and an ejection chamber 33 housing a cask carriage, etc., are provided. A dry thimble 36 capable of holding spent fuel assembly in an upright state is immersed in cooling water 35 in a water tank 34. An inert atmosphere is maintained in the dry thimble 36 and a forced circulating water system pool of a closed loop is formed on the outside of the dry thimble 36. Adhered Na is cleaned by the high-temp. inert gas blow of a fuel cleaning tank 24. The need for a pool water cleaning system, wet cell and water cleaning system is thereby eliminated and just one unit of the fuel transferring machine is necessitated. The system is thus simplified.

摘要： PURPOSE:To surely apply negative reactivity at the time of a low flow without impairing the control capability of a reflector and secure the safety of a reactor and the healthiness of core fuel by dividing the neutron reflector, and arranging gas expansion containers changed with liquid levels of a coolant between them. CONSTITUTION:A reactivity controlling neutron reflector 9 surrounding a core 2 is divided, and low-flow gas expansion containers 30 are arranged between the divided reflectors 9. The reduction of the control capability caused by the division of the reflector 9 is offset when the length of the reflector 9 is increased. The Na level at the time of the 100% output is adjusted by the sealed gas in advance to set the Na liquid levels in the containers 30 above the top section of the core 2 at the time of operation. The dynamic pressure of a coolant Na is reduced and the Na levels in the containers 30 are reduced at the time of a low flow, a radiation leak from the core 2 is increased, the reactivity P of a reactor is surely reduced, the mis-match of the P/F ratio is reduced, and the healthiness of the fuel of the core 2 and the safety of a reactor are secured.
