The use of statistical methods for assessing correction factors for assembly outlet coolant temperatures in the reactor core

An algorithm was set up for calculations of the so-called coolant temperature correction coefficients at the outlets from fuel assemblies; it is based on the regression method with regression curve order estimation. The algorithm has been tested in the Bohunice V-1 nuclear power plant. It can be implemented on minicomputers or microcomputers. Its drawbacks include high requirements put on the intermediate results buffer capacity and high costs required for testing the likelihood of the input data in the calculation part of the algorithm.
