Detailed information on nuclear physics states

Siempelkamp NIS provides the operators of nuclear plants with state-of-the-art software solutions which enable physicists and authorised experts to perform an optimum evaluation of the conditions in the nuclear technology environment.

Detailed information on nuclear physics states is collected on the basis of precise measurements and calculations. Siempelkamp NIS software solutions ensure the effective and correct operation of the plant.

DIKA is used to determine the core stability, i.e. the keyparameters of frequency (f) and decay ratio (DR) in a boiling water reactor. The program can continuously determine the distance to the stability threshold in order to prevent a reduction in the performance of the plant and an automatic switch-off.

With "incore fuel shuffling", the shuffler program system supports the shuffling of fuel assemblies in the pressurised water reactor and makes an effective contribution to considerably reducing the maintenance overhaul duration in pressurised water reactors.
