Summary: Arnie Gundersen is widely-regarded to be the best nuclear analyst covering Japan's Fukushima disaster. The situation on the ground at the crippled reactors remains precarious and at a minimum it will be years before it can be hoped to be truly contained. In the near term, the reactors remain particularly vulnerable to sizable aftershocks, which still have decent probability of occuring. On top of this is a growing threat of 'hot particle' contamination risk to more populated areas as weather patterns shift with the typhoon season and groundwater seepage.
