Abstract: The first method of the present invention includes the steps of: receiving from a user registered in advance the retrieval condition of qualification relevant information relating to the facilities management of a corporation to which the user belongs; obtaining the qualification relevant information corresponding to the retrieval condition from at least one of statute information and qualification information relating to the facilities management of the corporation, qualification information about a staff of the corporation, and information relating to a facilities manager of the corporation; and displaying the qualification relevant information corresponding to the retrieval condition on the terminal screen of the user.

Abstract: A fuel containment containing nuclear fuel rods of a fuel assembly which will be loaded into a reactor core of a fast breeder reactor is formed narrow in width at middle portion of vertical direction and long in length of vertical direction. And as being used in the reactor core, the middle portion of vertical direction of the fuel containment, wherein both of heat generation and swelling are larger than that of other portion, expands more than other portion, but undesirable contact with adjacent fuel assemblies can be avoided as the middle portion is previously formed narrow. Moreover, the other portions, wherein expansion of the fuel containment and undesirable contact with adjacent fuel assemblies are barely caused, are formed previously wide in width by enlarging the coolant flow path of the fuel containment, whereby pressure drop of coolant of coolant used in the reactor core can be reduced.
