MuUnited States, zvikamu zviviri kubva muzvitatu zvemareactors anotsikirirwa mvura reactor (PWR) uye mamwe ese ari kufashaidza mvura reactor (BWR).Mumvura iri kufashaira, inoratidzwa pamusoro, mvura inobvumirwa kufashaira kuita utsi, yozotumirwa neturbine kugadzira magetsi.
Mumagetsi emvura yakamanikidzwa, mvura yepakati inobatwa pasi pekumanikidzwa uye haibvumirwi kuvira.Kupisa kunoendeswa kumvura kunze kwepakati neinopisa (inonziwo steam jenareta), ichifashaidza mvura yekunze, ichigadzira chiutsi, uye kusimbisa turbine.Mumareactors emvura akamanikidzwa, mvura yakabikwa yakaparadzana nefission process, saka haiite radioactive.
Mushure mekunge chiutsi chashandiswa kusimbisa turbine, inotonhodzwa kuti iite kuti idzoke mumvura.Zvimwe zvinomera zvinoshandisa mvura yemunzizi, munyanza kana munyanza kutonhodza chiutsi, asi zvimwe zvinoshandisa shongwe dzinotonhodza dzakareba.Idzo shongwe dzekutonhodza dzakaita sehourglass ndiyo inocherechedzwa yezvicherwa zvakawanda zvenyukireya.Pachikamu chega chega chemagetsi chinogadzirwa negwenya remagetsi enyukireya, anenge mayuniti maviri ekupisa kwemarara anorambwa kune zvakatipoteredza.
Mafekitari emagetsi enyukireya ekutengeserana anokura kubva pa60 megawatts yechizvarwa chekutanga chezvirimwa mukutanga kwema1960, kusvika pamusoro pe1000 megawatts.Miti mizhinji ine inodarika imwe reactor.Palo Verde chirimwa muArizona, semuenzaniso, chinoumbwa nemareactor matatu akasiyana, rimwe nerimwe riine huwandu hwe1,334 megawatts.
Mamwe madhizaini emagetsi ekunze anoshandisa zvinotonhorera kunze kwemvura kutakura kupisa kwefission kure nepakati.Canadian reactors anoshandisa mvura yakatakurwa nedeuterium (inonzi "mvura inorema"), asi mamwe ari gasi akatonhodzwa.Imwe chirimwa muColorado, ikozvino yakavharwa zvachose, yakashandisa helium gasi sechinhu chinotonhorera (inonzi High Temperature Gas Cooled Reactor).Miti mishoma inoshandisa simbi yemvura kana sodium.
