TENAR program package is described, intended for numerical simulation of nuclear energy plant behaviour under different conditions, from rated duties to emergency ones, with equipment structure preserved.

       The package consists of a program collection, which enables one to simulate processes in the key elements of nuclear energy plants. The package includes the programs allowing the following processes to be taken into account: neutrons transfer and their interaction with medium; delayed neutrons and isotops depletion kinetics; heat-transfer agent flow in a circuit and in nuclear energy plants body; heat conduction in solid elements; thermal mechanics of fuel elements. The package can be supplemented with new components allowing the necessary processes to be considered.
