People fear. that people that terrorists are not stopped at the borders throughout europe and that the home country won t take them back. explain how you see this. well, you hit it right on the head, alisyn. first of all, the schengen zone, that opportunity to travel through all countries of europe was established several decades ago, and it allows this kind of travel. the criticality of all of this, though, is the information sharing between countries that have very good intelligence and security agencies, and those that might not be as robust or even as mature. and i think we ve seen this in this area. and you ve also seen, frankly, some 6 the countries who were accepting more refugees, immigrants and potential terrorists, as a base of travel to get into other countries. when i was commanding in europe we used to track rat lines as paul just mentioned the balkan rat line was a big one. how do terrorists move from the middle east, through europe, into the western part of europe, ....
Loud, you know, the dvd sound track to be over the air and block the frequency, i mean, that was an error, and it shouldn t have been tolerated, and of course, scrutiny is necessary. and i think that s what the administrator is doing with the president and natca is going around and reemphasize, you ve got to do your job, you have to be professional, and in this day and age right now with the criticality of your job, that is to keep air traffic separated, it s so important that you re fully alert when you show up to work, no matter what shift you are, and you maintain that highest level of professionalism. we try to do that with fire departments, police departments, and every other industry with regard to doing your job. but you re not going to have an infallibility with a human. greg feith, thank you for joining us. president obama is on h his way out west to california for a facebook town hall. it s all part of a trip with two major goals, win support for ....
What happens to those pellets? well, if all goes well, maybe the pellets fuse together in the shape they were being held in inside those metal straws. maybe they stay in an orderly little stack of tootsie rolls. if all does not go well, those stacks of pellets collapse and the uranium doesn t stay in those orderly rods, it gets into a big single molten pile. you ve heard the term critical mass, right? it is dramatic sounding when you re talking about bike protests. it is actually dramatic when you talk about where that term comes from. if the uranium melting down in a spent fuel pool or reactor is allowed to melt down completely and become one giant molten mass, tepco admitted this week that it is possible that nuclear fission could start again. they call that criticality. if that happened, there would be an explosion. and after all the efforts to prevent the worst from happening by trying to get water onto these fuel rods, in the event of a full meltdown if all the uranium became on ....
Possibly do. the boron absorbs neutrons and prevents criticality. it would also prevent recriticality. even if there is a substantial amount of fuel melt. so that s very important. and if, it is difficult to get fire trucks or whatever they re doing now in place to pump in more seawater, then, perhaps something will have to be done. megyn: that s the situation as we now know it, miller are. they re saying while the japanese are working furiously to get the fuel water, i m sorry, the seawater into these plants, the delivery system is not what they would like it to be and they re having serious difficulties maintaining that system such that, you know, the cooling systems are really, the original ones failed and the makeshift method of keeping these nuclear reactors cool does not appear to be working the way they wanted to. where could this go? ....
Temporary measure to do two things. make sure that there s no criticality. you can have a recriticality in that fuel if you re not careful. and you can at the same time with the lead, you can stop and dirt or sand, you can stop the gamma radiation which makes it very hard for workers to get anywhere near it. so it is a plus to do that. let s talk about some of the plans here. the japanese are focusing on reactor number three. they re trying to cool it down with fire hoses. yet one u.s. official quoted in the new york times said, this is more prayer than plan. so you agree with that criticism or do you think that there really is more that can be done especially if there is an international focus and japan actually opens up and lets other people come in to facilitate and help with the problem that they have there? well, a lot of the things that the workers at the plant have been doing look a little bit desperate. ....
