The present work discusses a segment of the calculational model of reactor calculation, the so called global reactor calculation. The design, the surveillance, safety analysis, the control, and the economic operation is based on models of the nuclear reactor. The models are complex, they require a large amount of input data ranging from the fine details of the geometry to the detailed isotope compositions of the various reactor materials. The input data feed a physical model describing the neutron population in the reactor core. Unfortunately the equations of reactor physics have only numerical solutions in the applications, so the reactor models are computer programs.
The global reactor calculation is the last element of a computation chain which starts with the processing of nuclear data library and continues with the fuel cell calculations, the fuel assembly calculation. All the above mentioned elements contribute to the success or failure of the global calculation.
The present work focuses on the physical and mathematical models of the reactor calculation. The mathematical models determine the problem to be solved, in details the equation, the boundary condition, the numerical procedure used to determine the solution. A practical problem, like the assessment of safety, requires the solution of several mathematical problems. Those working in the nuclear industry, or for a nuclear safety authority, should understand the nature and limit of the involved models.
