Modernized control of a pneumatic facility for short-time NAA at LVR-15 reactor in Řež, Czech Republic

An obsolete control unit of a fast transport (rabbit) system for short-time neutron activation analysis at the LVR-15 experimental reactor at Řež has been replaced. In the new system a PC is used to fully control the rabbit system and the subsequent gamma-ray spectrometry measurement. The modernization resulted in significant simplification of the operator work and improved documentation of the irradiation and spectra acquisition procedures. New nuclear safety features of the rabbit system are also described.
