摘要： PURPOSE:To enhance the reaction degree controlling ability of a neutron reflecting body without prolonging the length of the neutron reflecting body. CONSTITUTION:A neutron reflecting body 9 is installed outside of the core 2 of a nuclear reactor immersed in a cooling material 4 and moved up and down so as to adjust the leak of neutrons from the core 2, and thereby the reaction degree at the core 2 is controlled. In this nuclear reactor of reflecting body control type, the core in its portion positioned above the neutron reflecting body 9 is surrounded by a substance 24 whose neutron reflecting ability is inferior to the cooling material 4.

摘要： PURPOSE:To avoid the insertion of excess reactivity even for excess movement of neutron reflectors over a design set value. CONSTITUTION:Around a core 1, neutron reflector 12 is placed. This neutron reflector 12 is constituted of two semicylindrical unit reflectors 12a, 12b. These unit reflectors 12a, 12b are moved separately with drive devices 15 and 16. By this, neutron leak rate out of the core 1 increases compared with the case both unit reflectors are moved simultaneously.

摘要： PURPOSE:To enhance safety of reactor by shifting down the liquid level of coolant in the axial direction upon failure of the core. CONSTITUTION:In case of an output increasing failure, neutron flux and gamma-ray flux increase at the core section to cause increase of exothermic energy generated from an exothermic body 4. Consequently, the temperature of gas 8 encapsulated in gas plenums 2, 3 rises by thermal conduction and the volume of gas increases. As a result, the liquid level drops from a normal level 41 down to a fault level 42 lower than the upper end level 43 of core height. Neutrons leak axially upward from the fuel at the core through the gas encapsulated region to bring about a negative reactivity and thereby the output of core lowers thus settling the phenomenon. In case of a flow missing failure, the pressure of inner coolant 10 coupled with a coolant flow-in hole 9 lowers and the liquid level drops down to a level 45 lower than the lower end level 44 of core height. Neutrons leak from the core fuel through a gas 8 region in the axial direction to bring about a negative reactivity. Consequently, the output of core lowers and to settle the phenomenon.

摘要： PURPOSE:To flatten the output distribution, and also, to increase the reactivity value of a main reactor shutdown rod by limiting the reactor so that the reactor core becomes a subcritical state by inserting partially a backup shutdown rod and operating a scram function. CONSTITUTION:A main reactor shutdown rod 15 and a backup shutdown rod 16 are in an all inserting state in the case of a reactor shutdown state. In a rated output operation state in the beginning of a combustion cycle, insertion depth of the shutdown rod 15 is about 1/2, and as combustion of the reactor core advances, the shutdown rod 15 is drawn out, and the reactor core is always held in a critical state. At the time of an accident, scram functions of both systems operate, therefore, the reactor core becomes a subcritical reactor shutdown state. Even in the case the scram function of one system of them does not operate, the other system also has reactivity of a temperature compensation and a reactor shutdown allowance, therefore, since its scram function operates, even in any reactor core state, the reactor core becomes a subcritical reactor shutdown state. Especially, in the case of a rated output operation state, a large difference dows not exist in the insertion depth of a control rod, therefore, a neutron flux distribution is flattened, a reactivity value of the shutdown rod 15 increases, and also, sharing of output in a reactor core area 14 is flattened.

摘要： PURPOSE:To ease a demand requirement from a reactor core of the production of a fuel, by a method wherein fuel assemblies to be exchanged are classified by the weight in terms of fissile weight beforehand and so arranged that fissile weight is symmetrical in each of areas divided circumferentially. CONSTITUTION:Fuel assemblies to be exchanged are classified by the weight in terms of fissile weight beforehand and so arranged that the fissile weight is symmetrical in each of areas divided by 60 deg. circumferentially from the direction as reference of a reactor core. This can minimize effect on an output distribution to lessen a decrease in a terminal margin even when fuel assemblies are loaded onto the fuel fissile weight varied within an allowable range. This enables relaxation of a demand requirement from the reactor core in the production of the fuel, thereby realizing a reduction in cost for the entire FBR fuel cycle.
