20.500.12556/DKUM-38441 Primerjava reaktorske tlačne posode II. in III. generacije Comparison of reactor pressure vessel Diplomsko delo zajema splošno primerjavo reaktorske tlačne posode II. generacije z reaktorsko tlačno posodo III. in III.+ generacije, s konkretnimi predstavniki. Glavni del diplomske naloge je pregled scenarijev majhne izlivne nezgode za dva reaktorja III.(III.+) generacije in sicer EPR in AP1000. Za analize so uporabljeni rezultati, ki so pridobljeni s pomočjo testnega objekta APEX-1000, ki simulira reaktor AP1000 in testnega objekta PKL, ki simulira reaktor EPR. Rezultati prikazujejo termohidravlične razmere v primarnem sistemu reaktorja v primeru različnih scenarijev nezgod in potrjujejo začetno tezo, da so varnostni sistemi, v primeru majhne izlivne nezgode, zmožni popolnoma varno odvajati zaostalo toploto iz sistema. The diploma thesis contains basic comparison of reactor pressure vessel of II. generation and of the reactor pressure vessel of III. and III. + generation with concrete representatives. The main part of diploma thesis is the review of scenarios of small-break loss of coolant accident (SB-LOCA) for two reactors of III.(III.+) generation which are EPR and AP1000. For the analyses, results, gained with the help of test facility APEX-1000 which simulates the reactor AP1000 and test facility PKL that simulates the reactor EPR, are used. The results show thermohydraulic conditions in reactors’ primary system in case of different accident scenarios and confirm the earlier thesis that security systems are, in a case of small-break loss of coolant accident, absolutely capable to safely divert the residual heat from the system. reaktor NEK reaktor AP1000 reaktor EPR reaktorska tlačna posoda majhna izlivna nezgoda termohidravlični kriteriji pasivni varnostni sistem testni objekt APEX-1000 testni objekt PKL reactor NEK reactor AP1000 reactor EPR reactor pressure vessel small-break loss of coolant accident thermohydraulic criteria passive safety system test facility APEX-1000 test facility PKL true true false [G.
