I'm going back to the erm controversial emotive subject of atomic power I suppose, as you said earlier,the  the atomic bomb and erm I suppose the most worrying thing for er for everybody was when erm  the Cuba crisis was on and everybody was just waiting for these mushrooms to appear over London because we all thought we were gonna be bombed at any time but  er obviously the other thing that sort of worries people is other things that you said about Chernobyl and Three Mile Island  but on the other side, obviously the erm  the low cost of atomic power must be the advantage for the future.
