    • PURPOSE: A method for estimating the diametric creep of a heavy-water reactor pressure tube is provided to reduce a diametric creep estimation error by applying FNN(Fuzzy Neural Network) based on creep data. CONSTITUTION: Creep data is classified into training data and verification data(S1). An initial gene including a membership function variable is arbitrarily generated(S2). A fitness function of gene algorithm is calculated(S3). It is determined whether the fitness function is larger than a preset value(S4). Variables are changed by gene manipulation like selection, crossing, and deformation(S5). A membership function is generated based on a subtractive clustering method(S6). A consequent parameter of a fuzzy regulation function is obtained by using the least square method(S7). An FNN creep estimation model is corrected by using the membership function and the consequent parameter(S8). The uncertainty of the FNN creep estimation model is evaluated(S9). The final FNN creep estimation model is calculated(S10).

    • PURPOSE: A neutron measurement system using underwater wireless communication is provided to prevent the inflow of noise signals by reducing the distance between a neutron measuring instrument and the neutron measurement system. CONSTITUTION: A neutron measuring device, a neutron measuring system, and an underwater communication modem are integrated in a neutron measuring device housing for neutron counting rate measurement implemented during the initial core fuel charge of a nuclear power plant. An underwater communication modem installed outside a nuclear reactor receives and stores a neutron counting rate. The neutron measuring system comprises a high-voltage generator, a preamplifier, a signal amplifier, a D/A converter, and a pulse counter.
