Water radiolysis becomes a significant factor in explosive hydrogen generation and degradation of structural materials in decommissioning and waste management after nuclear severe accident such as loss of coolant accident (LOCA). Seawater used as coolant in Fukushima Dai-ichi Nuclear Power Plant (1F) Accident made the phenomena complicated. Advanced studies on water radiolysis for the 1F accident were described briefly in terms of seawater salts, coexistence of solids and engineering conditions.

Key words: severe accident; water radiolysis; seawater; adsorbent; liquid flow
