i spoke to paul norman, a professor of nuclear physics and nuclear energy at birmingham university. his, his assessment of the situation at the plant it's certainly a slightly elevated cause for concern than we had previously. i still believe that the chance is of some sort of wide spreads nuclear incident of pretty small. but the issue with the power lines is that you require electrical power in order to provide cooling, to the react, that would be to stable for sort of meltdown type situation. and what we had is the, so you have the main power line switcher, and now you have a reserve power line which is where we are at the moment. and then you have back up diesel generators as your sort of last main option if you like. so obviously we've knocked out one of the 3. so i think, you know, that raises the level a little bit. so after the, the last stage, the back up there, there's nothing else or other, any other measures that are in place or protocols in case of a meltdown. no, those are the main real back up mechanisms, you know, as long as most back up diesel generators working, th
