Энергия высвобождается при разрушении ядра атома, а его деление вызывает попадание в него ускоренных частиц(нейтронов) при этом часть нейтронов из ядер выбрасывается, часть превращается в протоны и бето-частицы, выброшенные нейтроны вызывают деление следующих, так запускается цепная реакция. Но в природном уране при делении атома высвобождается слишком мало нейтронов для поддержания цепной реакции и взрыва не происходит
