Asahi: Explosive hydrogen may be coming from melted fuel rods and “accumulating near the top of the containment vessel without being driven out”

Unidentified: 100% flammable gas in pipe connected to Reactor No. 1 — TEPCO working to ‘prevent blasts’ — Unknown where and how gas was created

Explosion Danger at Reactor No. 1? Worker says hydrogen levels over 4% in pipe leading to Containment Vessel — Mainichi: “Danger of explosion” if over 4%

Fukushima plant worker: Even higher than 10,000 millisievert/hr at many spots in reactor buildings 1, 2 and 3

Tokyo U. nuke expert: Radioactive substances may have “poured” into pipe during explosion — Levels could also be extremely high outside Reactors No. 3 and 4

Paper: TEPCO needs to check if high radiation doses are “spreading elsewhere” — Two more spots appear to be above 10 sieverts per hour, but no plans to actually take measurements

10+ sieverts per hour means there is direct exposure to fuel rods: Australia’s former top radiation official

Tepco: Ultra-high radiation levels may be from melted fuel that leaked out of containment vessel (PHOTO)
