Bodhi Cove Posted March 16, 2011 Share Posted March 16, 2011 Has anyone thought about whether there may be damage to the racks in the spent fuel pools? I mean, reactor #3 looks terrible from the outside and had a pretty massive explosion. I've been wondering about the same secondary and tertiary damage from the first hydrogen explosion, and those after. By no means am I even remotely knowledge of explosive shock-waves, but I ponder how much of the seals, pipes, supports, racks, and 40 year old, likely corroded containment shells were damaged or fatigued.

ThePhotoGuy Posted March 16, 2011 Share Posted March 16, 2011 Radiation Found on NBC News Crew, Lester Holt By Alex Weprin on March 16, 2011 1:46 PM Yesterday we reported that TV news crews were on the move due to fears of radiation exposure. Today we saw the first example of why those moves were made. On “Today” this morning, NBC News anchor Lester Holt revealed that he and his crew tested positive for small traces of radiation after returning to his hotel from spending time in the field. Luckily, as Holt explains, the amount of radiation he was exposed to was very small. His shoes, however, will not be coming back to the U.S. after his trip ends. http://www.mediabistro.com/tvnewser/radiation-found-on-nbc-news-crew-lester-holt_b57729# I don't remember this being posted but if it was, disregard.

During refueling operations, there is an absolute flurry of activity related to scheduled piping changeouts....radiographic "x-raying" of piping, valves, and other components...and general intensive inspections and testing. If cracks/damage are found during the scheduled piping radiography, they are replaced, right then and there. Thickness measurements are documented for the entire pipe, and ANY new blemishes are either noted or deemed significant enough to just replace the entire section of pipe. Every bolt on every pipe is tightened with torque wrenches per insanely detailed procedures. This, at least from my experience, is what takes place in the US nuclear facilities.

mempho Posted March 16, 2011 Share Posted March 16, 2011 All I have to say is bring on the wind turbines and solar cells. I was a proponent of nuke, but I have changed my tune with what I have learned this past week. Humans have proven themselves time and time again to be incapable of handling things like nuclear power. Who doesn't plan for a tsunami when building a nuke plant with six reactors right there on the Japanese coastline? Link to comment Share on other sites More sharing options...

Clinch Leatherwood Posted March 16, 2011 Share Posted March 16, 2011 I read a report on another site but have no link that ABC News is pulling their crews out of Japan. Breaking on abcnews.com "U.S. officials are alarmed at how the Japanese are handling the escalating nuclear reactor crisis and fear that if they do not get control of the plants within the next 24 to 48 hours they could have a situation that will be "deadly for decades." "It would be hard to describe how alarming this is right now," one U.S. official told ABC News." "They need to stop pulling out people—and step up with getting them back in the reactor to cool it. There is a recognition this is a suicide mission," the official said. "The U.S. official says experts believe there is a rupture in two, maybe three of the six reactors at the Fukushima power plant, but as worrisome is the fact that spent fuel rods are now exposed to the air, which means that substances like cesium, which have a long half-life, could become airborne. "That could be deadly for decades," the official said. There is a growing concern around the world that a nuclear catastrophic disaster is in the works. "There is talk of an apocalypse and I think the word is particularly well chosen," European Union's energy commissioner Günther Oettinger said today, according to various reports. "Practically everything is out of control. I cannot exclude the worst in the hours and days to come." Chu's assessment is in line with views expressed by many experts, some of whom even believe the Japan crisis could be worse than the 1986 Chernobyl nuclear disaster in Ukraine that left hundreds sick and killed several from radiation Something is up, the Japanese keep saying no big deal while everyone else is bailing.

I wonder if that's where some of the NRC's statements came from. could be. it was posted they would use it to check out the plant so it would make sense. the imaging on the global hawk is better than any one satellite and higher resolution... it should be able to uncover some previous unknowns.

From my own experience....cutting corners (wrt critical systems) is almost impossible, and is certainly not of much value (when assessing risk). During shutdowns/refueling outages, there are no shortage of regulatory personnel on site, not to mention that the cost of one section of pipe/valve/<insert component> is equivelant to about 3 seconds of revenue generated by the plant.....

I assume such standards are similar throughout most of the developed world.. Thank you for sharing your knowledge of the process. So, to your understanding, what could be damaged by the back end pressure release of the hydrogen explosions which have already occurred? I mean, if given the choice, would you have felt comfortable standing in a steel box at the base of one of those buildings, knowing there was going to be an explosion like the ones we've viewed? I don't mean to appear alarming. I'm simply trying to discern the strength and potential damage those explosions caused (some of which we may not even know about, until they get power reconnected) to the rest of the buildings.
