| 摘要 |
<p>The invention relates to a method for determining positions of fuel assembly elements arranged in a vessel, each fuel assembly comprising at least one element, at least one geometric constraint of the fuel assembly or the vessel being pre-defined, the method comprising the following steps: previously obtaining a first set of estimated positions of the elements; determining a criterion representative of the distances between the positions of the first set and parameters to be optimised, the parameters locating possible positions of the element, the possible positions respecting the pre-defined geometric constraint; and determining a second set of estimated positions optimised on the basis of said parameters for which the criterion is minimised as per a pre-determined norm.</p> |
