...international trade is universal-or is it? Take these-consecutive sentences, suggested by the phrasebook. "Whose invention is this? When was this invention patented? This is a Soviet invention." A more forthright approach is manifested by: "Show us your devices for outer space research work. How powerful is this reactor? Show me a working diagram of the reactor...
...aware that our physical environment is in danger. Yet how is it decided what are satisfactory solutions to the problems, and who are to be the decision-makers? If a group of experts decides that the East Side of Middletown would be a great site for a nuclear reactor, do the inhabitants of the area have any informed role in this decision? What is the probability of an accident in which there is emission of radioactivity to the inhabited surroundings...
Like ordinary nuclear reactors, breeders produce heat through fission-the familiar process of splitting unstable radioactive atoms by bombarding them with small, fast-moving particles called neutrons. As the atoms disintegrate, they release large amounts of heat that can be converted into steam and used to drive conventional turbogenerators. They also release additional neutrons, which in turn smash neighboring atoms and thus continue the heat-producing chain reaction inside the reactor...
...their promise, many design problems must be solved before breeders can produce electricity on a commercial scale. One difficulty lies in handling the coolant-the liquid or gas used to transfer heat from inside the reactor's core to a steam-producing boiler outside. Unlike conventional reactors, which use water as a coolant, the so-called liquid-metal "fast breeders" planned by the AEC will use liquid sodium, which is an extremely efficient thermal conductor. But since sodium also burns in air and reacts strongly with water, it requires elaborate safeguards to prevent a mishap that could leak radioactive...
Fish Stew. One of Midland's leading anti-reactor crusaders, Mrs. William Sinclair, nonetheless remains concerned that accidents in the plant might cause the release of dangerous radioactivity. "This is the first nuclear power plant of this size placed close to a large industrial and population center," she says. "We don't want to delay the plant, just study public-interest issues. Yet I'm now everybody's favorite villain." Last week, although it is the AEC's technical and procedural difficulties-not environmental opposition-that is causing the trouble, protesters littered Mrs. Sinclair...
