    摘要： A method for estimating a quantity of a system includes the following steps:



    for each variable of a plurality of variables, obtaining a sequence of successive measurements,
    determining a sequence of successive values of a stability parameter, the parameter being a weighted sum of rates of variation of the variables,
    identifying a time interval in which the stability parameter is less than or equal to a predetermined threshold for a duration greater than or equal to a predetermined duration,
    estimating a sequence of successive estimates of a particular variable, a start time of the sequence being included in the time interval,
    comparing the sequence of estimates and the sequence of measurements, in order to determine an adjustment parameter, and
    estimating the physical quantity of the system using the adjustment parameter.

    摘要： The invention concerns a method of estimating when dryout may occur in a nuclear light water reactor of the boiling water reactor kind. The method includes the use of a formula which expresses the local dryout property of the nuclear reactor. The formula includes at least a first and a second factor. The first factor is a first function that describes how the dryout property depends on the flow of the cooling medium through the nuclear fuel arrangement. The second factor is a second function that describes how the dryout property depends on the axial power profile of the nuclear fuel arrangement. The first and the second functions describe said flow dependence and said axial power profile dependence independently of each other. The invention also concerns a nuclear energy plant, a computer program product (23) and a method of operating a nuclear energy plant.

    摘要： AN APPARATUS, AND METHOD OF OPERATION THEREOF, TO CONTINUOUSLY MONITOR AND CONTROL THE NEUTRON ABSORPTION PROPERTIES OF CHEMICAL SHIM USED IN REGULATING REACTIVITY OF A PRESSURIZED WATER NUCLEAR REACTOR. COOLANTMODERATOR FLUID, INCLUDING THE SOLUBLE NEUTRON ABSORPTION PROPERTY IN THE CHEMICAL SHIM, IS CONTINUOUSLY PASSED THROUGH A CHAMBER HAVING PLURAL NEUTRON DETECTORS SURROUNDING A NEUTRON SOURCE OF KNOWN STRENGTH. UTILIZING THE NEUTRON ABSORPTIOMETRY PRINCIPLE, A SIGNAL REPRESENTATIVE OF THE CONCENTRATION OF THE ABSORPTION PROPERTIES OF THE CHEMICAL SHIM IN THE COOLANT-MODERATOR IS DERIVED. THIS SIGNAL IS THEN APPLIED THROUGH SIGNAL CONDITIONING MEANS TO A READOUT AND ALARM DEVICE SO THAT CONSTANT MONITORING OF THE SHIM CONCENTRATION ABSORTPION PROPERTIES MAY BE ACCOMPLISHED; ADDITIONALLY, THE SIGNAL MAY BE APPLIED TO MAINTAIN THE CONCENTRATION OF NEUTRON ABSORPTION PROPERTIES OF THE CHEMICAL SHIM IN THE COOLANTMODERATOR AT A DESIRED LEVEL.
