Robots from the Idaho National Laboratory (INL) are about to start work in the damaged Fukushima Daiichi nuclear plant.
Originally developed to assist with high-risk reconnaissance and the disposal of explosives and hazardous materials, The TALON has been modified for its new job.
The INL is also supplying Japan with radiation-sensing packages for Japanese robots, and a four person team to provide training and advice. NHK video
Larry Marek was trapped when 22.8 meters (75 feet) of the tunnel collapsed on him. Since then ten-member rescue squads, working 12-hour shifts, have cleared 9.7 meters (32 feet) of debris, trying to get to him.
It happened on Friday, April 15, at the Lucky Friday mine owned by Hecla Mining company. After digging about 7.6 meters (25 feet), rescuers had to focus on stabilizing the roof of the mine.
A robot digging machine arrived Sunday night, but they must assemble it inside the mine before they can use it.
The Lucky Friday mine has been operating since 1942. Watch AP video report
“We are doing every effort possible to expedite this in a safe manner. It is a rescue mission.”-Melanie Hennessey, Hecla Mining Compnay
The Lucky Friday Mine, in northern Idaho, collapsed Friday afternoon, trapping one employee. News of the collapse didn’t hit the media until Saturday.
There were two miners in the area when the tunnel caved in, one got out, the other is trapped. The trapped miner’s condition is not known. Equipment is being flown in to help with rescue efforts.
The collapse happened near the end of a 1,874 meter (6,150 feet) deep tunnel.
“This is something people are used to feeling, because when the rock burst happens, you can feel it all over town.”-Glen Gotcher, veteran miner
The mine is located near Mullan, Idaho, a town of about 840 residents. Hecla Mining is expanding its silver mining operation, thanks to the higher prices for silver. They have a good safety record at the mine, but did get fined for water contamination in 2009.
In a National Geographic article, researchers say the magma under Yellow National Park, is even bigger than before.
The latest scans of the super volcanic plume under Yellowstone, measured electrical conductivity, and is described as being like a giant medical CT scan.
Scientists now say the super volcanic plume extends 643km (400 miles), that’s increased from the 241km (150 miles) detected in 2009. Back then scientist predicted that the plume was actually larger, and the new scanning technique proved them correct.
They also discovered that hot, salty water surrounds and is mixed in with the plume.
The French company Areva SA is increasing the number of nuclear experts they’ve sent to Japan, to help deal with the Fukushima Daiichi crisis.
Areva SA now has 15 technicians in Japan. Some of the technicians specialize in removing contaminated water, and dismantling nuclear power plants.
France based Areva is also trying to get a uranium enrichment operation built in Idaho, U.S.A.

Across a cold windswept east Idaho desert, people say you can hear the nuke train haulin’ its contaminated cargo. The short track rails start nowhere, and end nowhere. You might even see the sickly yellow locomotive yourself, if your lucky and don’t miss the turn off (for directions see earlier posting “Ancient Nuclear Powered Jet…”).
Lead-lined train in the Arco desert in Eastern Idaho.
OK, so there’s no ghost train, but, in the middle of nowhere, along side the world’s first nuclear powered jet engine, sits an odd shaped yellow locomotive. It’s not nuclear powered, but it is lead lined, to protect the crew from radiation exposure when hauling the huge HTRE units that make up the nuclear jet engine.
General Electric, who ran the nuke jet project, had rail lines built to haul the huge engine from one test area to the next. In a 2005 document, the Department of Energy explained that “shielding” of various equipment from radiation, like the lead-lined locomotive, were based on 1950s understandings of radiation.
Two sets of tracks were laid for the program. The locomotive rode on the inner rails of the two tracks, pulling, or pushing the HTRE units. The HTRE units rode on both sets of tracks, they were that wide. (More pics in the “Galleries” section, click on the “INL Nuclear Power Site” pic. Click on the pics to make them bigger.).
The nuke train had a top speed of 3.5 miles per hour, but, for safety reasons traveled at 2.5 mph. For a detailed (and boring) explanation you can go to this website: www.inl.gov/technicalpublications/Documents/3028280.pdf Supposedly there are period photos in the document, but they didn’t show up for me.
The Idaho National Laboratory (INL) used to be known as INEEL, before that INEL, before that ERDA and before that NRTS. The names changes coincide with changes in government agencies controlling the “site”, in the early days, and changes in contractors who now run the site.
I’ve been checking the Idaho RadNet web site and have gotten frustrated because it’s become clear Idaho DEQ is not updating the site. I checked it today, 08 April 2011, @ 11:00AM Mountain Time, and the RadNet posting is still for 06 April 2011.
Recently the Associated Press reported how the RadNet monitors are not reliable.
On top of the Idaho RadNet web site not being updated, the text portion seems to be the same as it was last week, or, Idaho is still getting hit with iodine-131 and xenon-133.
The numbers that RadNet posts are in Beta counts per minute, which is how a Geiger counter reads. The problem, reveled by University of California Santa Cruz professor, Daniel Hirsch, is that there are no set universal standards regarding how much radiation exposure is “bad”.
One source says they consider 100 counts per minute as “bad”. Well, if you look at the Idaho RadNet web site, you’ll see counts as high as 300. However, if you try to use the RadNet web site explainer pages, to figure out if you’re safe or not, you only get more confused.
“The monitoring system isn’t functioning fully.”-Daniel Hirsch, University of California Santa Cruz
Hirsch said that EPA is too slow in releasing data about the radiation from the nuclear accident in Japan. Some RadNet monitoring systems have been offline for months.
The Associated Press, quoting the Environmental Protection Agency’s own website, said as many as 20 of the RadNet sites were down. Also, 38% were under “review”. When a RadNet site is under review, it means that the officials are doubting the readings.
Daniel Hirsch pointed out that radiation exposure standards from one government agency to another are different, which adds to the problem of letting people know if they are at risk or not. It also explains why some “experts” disagree with other “experts” about the dangers from Japan. There is no set standard for radiation exposure!
This explains a lot of the confusion in Japan during the first two weeks of the nuclear disaster. I remember watching press conferences where it seemed officials from one agency contradicted officials from another agency. You’d think when it comes to nuclear power there would be a set universal standard regarding radiation exposure!
On 22 March 2011, the Federal Environmental Protection Agency reported rain water contamination numbers for Idaho. Do you understand them?
The EPA reported 242 pCi/L of I-131. Understand? pCi means Picocuries. I-131 means iodine-131. L means liters. 242 Picocuries per liter of iodine-131. Should you be worried? Yes!
The Federal government set safe levels of iodine-131, in drinking water, at 0.111 Becquerels per liter. Using a Picocurie to Becquerel conversion program I discovered that the March 22 readings worked out to 8.954 Becquerels per liter, more than the government’s safe limits.
The EPA levels were in rain water, but rain water is used for livestock, and ends up in many municipality’s water systems.
The U.S. Environmental Protection Agency says they have found trace amounts of iodine-131 in drinking water in the states of Washington and Idaho.
The samples were taken last week, at Boise, Idaho and Richland, Washington. The results were just released.
The EPA also says they picked up trace amounts of radiation in rain water.
I checked the Idaho RadNet site and, so far, there is no mention of the water tests by the EPA. The information is in the most recent EPA press release.
