Fukushima Frozen Wall Not Solid, What You Need To Know

Fukushima Frozen Wall Not Solid, What You Need To Know

Last week TEPCO admitted that the frozen wall would not fully contain groundwater flowing through the plant. Original estimates of groundwater flowing through the plant were about 600 tons per day. The frozen wall will allow 50 tons per day to flow through the reactor block area. While this is a significant reduction, it isn’t water tight. This is the first time this has been disclosed to the public. Some reasons why it may not be water … Read entire article »

Fukushima Tritium Dumping Plan More Dangerous Than Advertised

Fukushima Tritium Dumping Plan More Dangerous Than Advertised

An Associated Press story made the rounds this week quoting various experts regarding potential tritium dumping at Fukushima Daiichi. Some of these expert statements are giving the public a misleading understanding of the situation and the risks. One statement by NRC head Shunichi Tanaka claimed that “Tritium is so weak in its radioactivity it won’t penetrate plastic wrapping,” This is a deceptive statement, though maybe not intentionally so by Tanaka. Tritium is a beta emitter and beta emitters are … Read entire article »

Fukushima Unit 2 Gets Mini Muon Detector

Fukushima Unit 2 Gets Mini Muon Detector

Unit 2 already had one muon scan done by Nagoya University that found no fuel to likely be in the reactor vessel. They did have a small level of uncertainty because they were unable to image the very bottom of the reactor vessel. This caused them to say there was a chance some fuel debris could remain in the bottom of the reactor vessel. A recent scope inspection of unit 2′s reactor pedestal included a … Read entire article »
