A new technology for the training of engineers is offered, named as of Professional Activity Imitation Education Technique (PAIET). This technology is being tested at the National Research Nuclear University (NRNU MEPI) for many years. Its basis is establishment of training equivalent of professional activities of specialist after graduation. In order to ensure the rapid reproduction of skills and functions of engineering activities by students, they are included in the "habitat" and they participate in the implementation of real projects. In the process of scientific and devise work, as well as learning sessions, they gain experience and skills of real engineering activities.
