Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mazhinji ma fission reactors ma thermal-neutron reactors anoshandisa neutron moderator kunonoka ("thermalize") ma neutron anogadzirwa nekupatsanuka kwenyukireya. Kuenzanisa kunowedzera zvikuru chidimbu chemuchinjikwa chenyukireya dzinoputika dzakadai seuranium-235 kana kuti plutonium-239. Mukuwedzera, uranium-238 ine mucheto wakaderera wekubata neutron inopisa, ichibvumira ma neutron akawanda kukonzera kupatsanurwa kwezvinyorwa zvinopatsanuka uye kuparadzira chain reaction, pane kubatwa ne238U. Mubatanidzwa wemigumisiro iyi unobvumira zvigadziri zvemvura zvakareruka kushandisa uranium yakaderera. Heavy mvura reactors uye graphite-moderated reactors vanogona kunyange kushandisa uranium chaiyo sezvo izvi moderators vane yakaderera zvikuru neutron kubatwa muchinjikwa zvikamu pane chiedza mvura. A kuwedzera mafuta tembiricha zvakare kunowedzera U-238 kuti chafariz neutron Absorção de Água kubudikidza Doppler broadening, ichipa kunaka inofambiswa kubatsira kudzora chidhiraivho. Uyewo, kana moderator ariwo kutenderera inotonhorera (chiedza mvura kana mvura inorema), anobuda inotonhorera kuchaderedza moderator arambe achirema uye zvinopa kunaka inofambiswa (kunaka void coefficient).  Mubvunzo: Chii chatinoreva kuti thermalize?
