As the fourth year of the Fukushima Daiichi nuclear catastrophe is about to begin on March 11th, Natural Resources Defense Council (NRDC) has published a report, Preventing Hydrogen Explosions in Severe Nuclear Accidents: Unresolved Safety Issues Involving Hydrogen Generation and Mitigation. This report was authored by nuclear safety consultant Mark Leyse. Christopher Paine, who served as contributing editor on the report, has published a blog. NRDC has also put out a press release.
