摘要： A computer implemented method for modelizing a nuclear reactor core, comprises the steps of: - partitioning the core in cubes (10) to constitute nodes of a grid (12) for computer implemented calculation, - calculating neutron flux by using an iterative solving procedure of at least one eigensystem, the components of an iterant of the eigensystem corresponding either to a neutron flux, to a neutron outcurrent or to a neutron incurrent, for a respective cube (10) to be calculated. The neutrons are sorted in a plurality of neutron energy groups, and the eigensystem iterative solving procedure comprises a substep of conditioning the eigensystem into a restricted eigensystem corresponding to the eigensystem for a selection of some neutron energy groups.

摘要： In a computer-implemented method of designing a nuclear reactor of a given reactor plant, an initial, test reactor core design is generated for the given plant based on a plurality of limits input by a user. The limits include a plurality of transient licensing constraints to be satisfied for operating the given plant. The method includes selecting, from a set of automated tools, one or more automated tools (700) to evaluate the test core design, and operating one or more of selected automated tools to output data for display to the user. The displayed data is related to a core design that satisfies the limits inclusive of the transient licensing constraints.

摘要： In the method, a set of limits applicable to a test rod pattern design are defined (S10), and a sequence strategy for positioning one or more subsets of the test rod pattern design is established (S20). Reactor operation on a subset of the test rod pattern design, which may be a subset of fuel bundles in a reactor core for example, is simulated (S30) to produce a plurality of simulated results. The simulated results are compared against the limits (S40), and data from the comparison is provided (S50) to indicate whether any of the limits were violated by the test rod pattern design during the simulation. A designer or engineer may use the data to determine which operator parameters need to be adjusted (e.g., control blade notch positions for example) in order to create a derivative rod pattern design for simulation, and eventually perfect a rod pattern design for a particular core.

摘要： The invention relates to a computer modelling method for the core (1) of a nuclear reactor, according to which the core (1) is divided into a plurality of primary grids (2), whereby a sub-section (8) of the core (1) relating to at least one grid (2) is assigned to said grid. The sub-section (8) comprises said grid (2) and a buffer zone (10), which surrounds the grid on the horizontal plane and contains at least the grid (2) that lies immediately adjacent to the first grid (2). The sub-section (8) is sub-divided into a plurality of secondary grids (6), which are smaller than the primary grids (2). In a first computing step, a model of the core (1) is calculated using a nodal calculation method, based on a respective dataset that is assigned to each primary grid (2). In a second computing step, a respective second dataset is assigned to each secondary grid (6) of a sub-section (8) and a model is then calculated for the sub-section (8), based on said dataset and the flows (J) on the border of said sub-section (8) that have been calculated in the first computing step.

摘要： There are provided a method of synthesizing axial power distributions of a nuclear reactor core using a neural network circuit and an in-core protection system (ICOPS) using the same, in which using the neural network circuit including an input layer, an output layer, and at least one hidden layer, each layer being configured with at least one node, each node of one layer being connected to nodes of the other layers, node-to-node connections being made with connection weights varied based on a learning result, optimum connection weights between the respective nodes constituting the neural network circuit are determined through learning based on various core design data applied to the design of a nuclear reactor core of a nuclear power plant, and axial power distributions of the nuclear reactor core are synthesized based on ex-core flux detector signals measured by ex-core neutron flux detectors during operation of a nuclear reactor, so that the initial time required to perform a start-up test of the nuclear reactor can be reduced since basic data for synthesizing axial power distributions need not be separately measured in the start-up test of the nuclear reactor contrary to a conventional ICOPS, thereby improving the economic efficiency of the nuclear power plant, and so that overall nuclear reactor core design data can be used rather than actual measurement data in the start-up test (i.e., at the beginning of a period of nuclear fuel), thereby more accurately replicating axial power distributions of the nuclear reactor core throughout the overall period of the nuclear fuel.
