摘要： In an initial core constituted by various kinds of fuel assemblies having a different average enrichment of uranium 235 four fuel assemblies having the lowest average enrichment constitute a square shaped cell. Three fuel assemblies having the highest average enrichment constitute an L-shaped cell, and the L-shaped cell is arranged at corners of the square shaped cells, whereby each assembly of the L-shaped cell adjoins a square shaped cell. The ratio of the number of assemblies of the L-shaped cell to the total number of fuel assemblies in the core is 10% or more.

摘要： In an arrangement of an initial core, the core is loaded with 572 high enrichment fuel assemblies H with 4.2 wt % average enrichment and 300 low enrichment fuel assemblies L with 1.5 wt % average enrichment. The average enrichment of the core is about 3.3 wt %. In this core, only the low enrichment fuel assemblies are loaded into the most outer position of the core and the high enrichment fuel assemblies are loaded into an area other than the most outer position. In this arrangement, the average enrichment of reload fuel assemblies is 3.7 wt %.

摘要： Several unit loading patterns are arranged in the central area of an initial core to which the present invention is applied. The unit loading pattern is composed of one square-shaped unit cell and four cross-shaped control rods 3 which surround the unit cell. The unit cell is composed of one low enrichment fuel assembly 7, two high enrichment fuel assemblies 8 and one high enrichment fuel assembly 9. The low enrichment fuel assemblies 7 of each unit loading pattern adjoin each other and are arranged to constitute the first control cell 2a being square-shaped. The high enrichment fuel assemblies 9, obliquely adjoining the low enrichment fuel assembly 7 in each unit loading pattern, adjoin each other and are arranged to constitute the second control cell 2b being square-shaped. The high enrichment fuel assembly 9 constituting the unit loading pattern is divided into a control rod side area and an anticontrol rod side area by a diagonal line L1, and the number of Gd fuel rods in the control rod side area is 2 or more than the number in the anticontrol rod side area. By providing this structure, the increase of the local peaking factor on the control rod side can be suppressed and the thermal margin can be sufficiently secured, even if the control rod 3 of the second control cell 2b is extracted after the second operation cycle.

摘要： A fuel assembly includes a plurality of fuel rods placed in a square lattice array of 9-rows/9-columns and at least one water rod. In this fuel assembly, the fuel rod pitch of the plurality of fuel rods is in a range of 14.15 mm to 14.65 mm, and means for offsetting and holding a fuel bundle composed of the fuel rods and the water rod is provided in such a manner that the center in a cross section of the fuel bundle is offset from the center in a cross section of the lower tie plate toward the channel fastener side. With this configuration, it is possible to provide a fuel assembly for a D-lattice core, which is capable of achieving the fuel economy comparable to that of a C-lattice core without reducing the thermal margin, and of using the existing fuel spacers.

摘要： A nuclear fuel assembly has an array of fuel rods comprising a plurality of first fuel rods each containing nuclear fuel material but not containing burnable poison and a plurality of further fuel rods each containing both nuclear fuel material and burnable poison. The further fuel rods comprise second fuel rods and third fuel rods, and each second fuel rod has at a lower region of the fuel assembly a burnable poison concentration which is a minimum burnable poison concentration in the further fuel rods. To increase the effectiveness of the second fuel rods in controlling axial power peaking, as seen in plan view on the array, the first fuel rods are the nearest neighbors of each further fuel rod.

摘要： A fuel assembly has a plurality of first fuel rods each of which contains nuclear fuel material but does not contain burnable poison, and a plurality of second fuel rods each of which includes nuclear fuel material and burnable poison. The amount of burnable poison in a lower region of the fuel assembly is smaller than that in an upper region thereof. When each of the second fuel rods is divided into an upper region and a lower region, a region of the divided regions in the second fuel rods containing a maximum burnable poison concentration Gmax and a region of the divided regions in the second fuel rods containing a minimum burnable poison concentration Gmin are located in the lower region of the fuel assembly. The burnable poison concentration of the upper region of each second fuel rod is between Gmax and Gmin. The fuel assembly may moderate a maximum linear heat rating with an increased spectral shift effect.

摘要： An IP-PBX has a software-based built-in control unit, a card slot into which a control card is plugged, and a data bus connecting the software-based control unit and the card slot. The software-based control unit includes a first management unit managing up to a first number of IP terminals, and an IP terminal registering unit connected to the first management unit and the card slot. The control card includes a second management unit managing up to a second number of IP terminals. The IP terminal registering unit compares a current number of IP terminals managed by the first management unit with the first number when an IP terminal requests communication. The IP terminal has an ID number and an IP address. If the current number is smaller than the first number, the IP terminal registering unit associates the first management unit with the ID number and the IP address, and the first management unit manages the IP terminal. If the current number is equal to the first number, the IP terminal registering unit associates the second management unit with the ID number and the IP address, and the second management unit manages the IP terminal.

摘要： A nuclear fuel assembly for a nuclear reactor has a plurality of vertically extending fuel rods arranged side by side in a square array and containing fissile material. The array has two adjacent first sides which are next to a control rod region of the core and two adjacent second sides which are next to a non-control rod region of the core. When the rods of the array as seen in horizontal cross section, excluding the rods lying on the diagonal line joining the opposite corners of the array at which the control rod region meets the non-control rod region, is divided into four regions which area: the rods in the row and column of said array adjoining said first sides;b: the rods lying between said region a and said diagonal line;c: the rods lying between said region d and said diagonal line,d: the rods in the row and column of said array adjoining said second sides and; over at east part of the height containing fissile material, the average concentration of fissile material per fuel rod is higher in said region b than said region c and by at least 5% and, among all said regions a, b, c, d, is a minimum in said region a. This provides good control rod worth and low local power peaking.
