...call an "excursion" -i.e., started to react too fast -it could be slowed down by pushing into it a simple rod of neutron-absorbing material. Control rods are still used, but the operators of big modern reactors dare not depend on them alone. Under some conditions, the fierce nuclear fire in the reactor's core can make a disastrous excursion in a fraction of a second...
...reactor rise above a critical level, showing that an excursion has started, the uranium fissions at a rate that creates enough heat to melt the solder. Then high-pressure gas will shoot neutron-absorbing poison into the reactor. Even if other controls have failed, this last-ditch nuclear fire extinguisher will keep the reactor from exploding or melting itself into radioactive...
...invisible, cosmic radiation particles pierce the space capsule -and riddle the pilot -harmfully or harmlessly, who knows? By then the space traveler is weightless -an unearthly state in which he may do himself injury with normal movements of his own muscles. He cannot smoke because of fire and explosion hazards; the cabin pressure is so low that he cannot even whistle to keep up his courage. Yet he needs courage of a very special kind. As great a menace as any lies in his own mind: a degree of isolation unknown to earth dwellers strains at the bounds...
