The conference is mainly designed to the PhD students of the program “New reactor concepts and safety analysis for the Polish Nuclear Energy Program”. There is no registration fee for the participation in the lectures. However, some other participants may attend only after making appropriate inquiry to the chairman of the Organising Committee Dr. Karol Kowal (Karol.Kowal@ncbj.gov.pl) and being accepted. If so, they will have to arrange accommodation and meals on they own covering all the expanses through the local hotels. The details of such a procedure can be consulted with the Organising Committee.
