Plugging Radiation Emissions Not Part of Tepco's New Plan

Hat tip

This is a good article on Tepco's plans to contain the ongoing Fukushima disaster

Published on Thursday, July 21, 2011 by the Japan Times Plugging Fukushima Reactors No Longer Stated Goal for Tepco

by Kazuaki Nagata

(excerpted) To substantially reduce the amount of radioactive materials released from the plant, Tepco needs to get to the bottom of the problem: plugging holes or cracks in the reactors' containment vessels that are allowing contaminated water to flood on-site facilities, including the reactor buildings and turbine buildings, experts said.

The updated road map, however, includes no reference to this critical work in the second stage, even though it was mentioned in past plans. And without fixing this problem, it is difficult to say that the release of radioactive materials is under control.

"In terms of managing the leakage of radioactive materials, I think plugging the holes will be the most important point," said Tsuyoshi Misawa, a professor of reactor physics at Kyoto University's Research Reactor Institute, adding he was perplexed it wasn't included in the new plan...."

MAJIA HERE: READ THE REST OF THE ARTICLE AND THE COMMENTS. I'm reposting one of the comments I think should be considered when thinking about Tepco's roadmap

"This article is very misleading in the extreme-there are no leaks to plug

The meltdown at the reactors was complete and utter-the melted fuel is lying in a 270 ton (90 tons per reactor) pile in the vicinity of the plant.

Nuclear fuel melts at just over 5,000 degrees F. There is no known material on the planet that will contain substances at that temperature for more than 10 or 12 hours"
