the tokyo electric power company is able to basically control the information while the accident remains out of control and that's a big concern that is a big concern they've been really tight lipped on a lot of things paul let's talk about the ice wall. that we keep hearing about the . one point five kilometers of underground i's been built to keep the soil around the reactors froze and i mean one of the major problems with this idea well again this is another experiment it's unprecedented to use this kind of technology which has a very limited history where they've been able to free ground under large bodies of water so the they could dig tunnels but again this is just a temporary procedure we're talking about. putting. piping down to bedrock ninety feet down into the ground spacing these pipes every three feet for more than a mile to put a perimeter that then they will pump refrigerant into the pipes to try to get the the temperature down to minus twenty degrees fahrenheit and they're anticipating that this will then freeze the water that's flowing from the mountains behind the fukush

tokyo electric power company has completely lost control of basically two sources of radioactive water that are flowing into the plant and these three destroyed reactors and then flowing out back into the pacific ocean one flow is from all the cooling water that's washing over these three melted cores to keep the accident from blowing into another full blown catastrophe the other source of water is ground water flowing into the wreckage and you know they've basically have lost control of all this they've been trying to pump it into this huge tank form that's now probably more than fifteen hundred tanks that are accumulating water saturated with radioactive strontium cesium and they've been trying to filter this out in a in a test procedure an experiment that's going on there to try to gear up so they can filter radioactivity out but again this is only a test it's been up and down it's broken it's failed it's leaked and this is ongoing i think once people see the process that's when it really settles out of how horrific the situation really is because yeah they're they're filling up fre

officials at tokyo electric power company discovered the water pressure at this depth was lower than a layer above it. they say this makes it easier for con tamed water to spread in the deep layer. they suspect radioactive water could be spilling into the ocean. tepco officials say the cause of the problem could be the ongoing construction of a seaside barrier. the work involves drilling into the deep layer, and this could be to blame for the lower pressure. now, officials say they will speed up construction work on the barrier due to be completed in the fall. >>> militants have reportedly taken more than 60 women and girls in northeastern nigeria. officials suspect it's the work of islamist extremist group boko haram. the abductions took place in a part of the country worst affected by the group's increasing attacks. local media say the militants raided a village outside maridugruri, capital of borno state. in april members of boko haram took more than 200 schoolgirls. the united states and other countries sent experts to nigeria to help with rescue efforts, but so far they've faile

. >>> officials at tokyo electric power company are facing another setback in their efforts to decommission the fukushima daiichi nuclear power plant. they found the level of water in one of the reactors is lower than they thought. they say they don't know whether it even covers all the nuclear fuel inside, nhk world's yuri ito has more. >> reporter: the march 11 earthquake and tsunami led to meltdowns at three of the plant's reactors. but officials don't know about the condition of the melted fuel inside. they've been trying to cool the fuel by filling the reactor containment vessels with water. but water has been leaking from the reactors. earlier this month, workers used a probe to measure the level and temperature of water inside the vessel at the number 2 reactor. a similar measurement two years ago led them to estimate the water was 60 centimeters deep. but now they've found it's only around half that. officials believe the water level at another reactor is about 10 times deeper. >> translator: we cannot tell at this point whether the fuel is entirely submerged, or if part of it is ab

melted down in the wake of a massive tsunami but the problems just keep on coming tokyo electric power or tepco the company that runs the plant is now stumbling through yet another part of the effort to keep the already dangerous situation from getting even worse on tuesday tepco officials announced that they were having a hard time constructing an ice wall that once fully up and running would stop clean water from the surrounding countryside from getting contaminated with toxic waste water from the plant so what exactly is an ice wall in the first place and even if tepco does manage to build one will that really keep things under control. joining me now for more on this is kevin camp's radioactive waste watchdog nuclear dot org kevin welcome back to the program. kevin camp is their area so they can have it so i swatted it sounds like sounds like something out of science fiction movie tell us about it. well i just like the center game of thrones there are weaknesses in this ice floe plan weather while the winds go over the wall around the onset of all three sima daiichi they're trying to free say the groun
