核かく分ぶん裂れつ連れん鎖さ反はん応のうが臨りん界かいに達たっすると、持じ続ぞく的てきにエネルギーが放ほう出しゅつされる。

When the fission chain reaction reaches criticality, energy is released continuously.

核かく分ぶん裂れつ
Nuclear fission itself; 核分裂連鎖反応 is the chain reaction resulting from successive fissions.
連れん鎖さ反はん応のう
Chain reaction in general; 核分裂連鎖反応 specifies a nuclear fission chain reaction.

Compound of 核分裂 (nuclear fission) + 連鎖 (chain) + 反応 (reaction). A direct calque from English 'nuclear fission chain reaction'.
