...temperatures cause the fuel to expand, which increases the distances between individual atoms and makes it less likely that the neutrons emitted by one will hit the nucleus of another. But the spontaneous radioactive decay of nuclei goes on. The uncooled reactor core could eventually get hot enough to melt through its casing and the surrounding building, causing fires that loft radioactive material into the atmosphere. Under the worst circumstances, the core melts through the earth and in a "China Syndrome" reaches the underground water table and triggers the further release of radioactive particles. In an effort to minimize...

...MHTGR, in contrast, has no safety cooling system at all; the helium gas flowing through its core merely carries away heat to power electric generators. The reactor itself can never get hot enough to melt down. In the MHTGR, bits of uranium fuel are encapsulated in tiny grains made of carbon and silicon compounds. The fuel particles, which are embedded in racquetball-size "pebbles" of graphite, will remain intact up to 3600 degreesF. But the configuration of the core and the reactor's size (it generates only 80 megawatts of power, compared with 1,000 megawatts for large conventional reactors...

...GnRH is released in bursts by the hypothalamus gland, eventually triggering the process of ovulation. But "if the GnRH stimulation is given continuously instead of in pulses," explains Dr. Robert Jaffe of the University of California, San Francisco, "the whole (ovulatory) system shuts off," and the endometrial implants "virtually melt away...

...featuring meals from the plan's menu; grocery stores are posting signs touting approved fruits, vegetables and other foods. So popular has the plan become that an estimated 70,000 residents, about 10% of the city's population, are now rotating feverishly, caught up in a mad whirl to "Melt-a-Million" pounds collectively by mid-May. They are hoping to create a whole new category for the Guinness Book of World Records...

...expected to draw 80 registrants, were stampeded by 1,400. At Vanderbilt, telephone operators were swamped. Some 25,000 requests for brochures on the diet arrived by mail within three weeks. A natural salesman, Katahn seized the opportunity to turn personal frenzy into a community mania and launched the "Melt-a-Million" campaign in mid- February...
