    Thehigh-temperaturegas-cooledreactor(HTGR)appearsasagoodcandidateforthenextgenerationofnuclearpowerplants.Inthe“HTR-N”projectoftheEuropeanUnionFifthFrameworkProgram,analyseshavebeenperformedonanumberofconceptualHTGRdesigns,derivedfromreferencepebble-bedandhexagonalblock-typeHTGRtypes.ItisshownthatseveralHTGRconceptsarequitepromisingassystemsfortheincinerationofplutoniumandpossiblyminoractinides.
