Calculation of NPP Krsko response during turbine trip

Ovaj završni rad opisao je ponašanje primarne strane nuklearne elektrane tijekom ispada sa mreže ili tripa turbine. Opisane su osnovne komponente primarnog i sekundarnog kruga te njihova međudjelovanja. Također, opisan je rad kontrolnih i sigurnosnih sustava i njihova uloga i utjecaj koji imaju na osiguravanje funkcioniranja cjelokupnog sustava. Prilikom proračuna korišten je program RELAP5, a odzivi koje smo dobili pokazali su kako tranzijenti utječu na pojedine varijable komponenti sustava.This final work describes behaviour of the nuclear power plant during major loss of load or turbine trip. Some of the basic components of the primary and the secondary system are described, as well as their interactions. Also, control and safety systems are described, along with their functions and influences on the proper operation of the whole power plant. During the calculations, computer program RELAP5 was used and the responses of the system showed us how transients affect certain variables of the system components
