...Argonne National Laboratory outside Chicago. Any sudden rise in temperature will halt the experimental reactor within minutes. The system performed flawlessly in its initial test last April. A similar Swedish unit called PIUS (Process Inherent Ultimate Safety) floods with water in the event of a mishap; the boron-treated liquid instantly stops the reactor. West Germany is experimenting with small modular units that can be cooled more quickly and efficiently than the present generation of nuclear behemoths...
Thousands of laborers set about sealing off the reactor and cleaning up nearby areas last week. Helicopters continued to drop tons of sand, lead and boron onto the reactor each day to keep radiation from reaching the air. On the ground, crews worked to seal off the 570 degrees mass from the soil and water below. The news agency TASS reported that at one crucial point, three men in protective garments dove into a pool that had collected beneath the reactor and opened valves to let the water out. That ended the danger that the reactor could fall into...
...reactor continued to burn, military helicopters reportedly flew over the site and dropped wet sand, lead and boron onto the burning reactor. Available evidence at week's end suggested that the fire was dying...
...warehouse, an A-framed former Grace Evangelical Lutheran Church, Grothus points out things at random. "Boron-loaded polyethylene, a neutron absorber. Who the hell wants it? I've got twelve or so 400-channel analyzers. Stacks of nuclear-instrumentation modules. IBM card punches and readers-obsolete by our standards. But if a country has nothing? Scintillation crystals. Electronic balances." Grothus supplied the technical props for the Karen Silkwood movie. He was horrified when they were returned. "You can't get rid of this stuff," he moans. "Do you need a five-beam oscilloscope? Nobody on earth...
...York State's Carborundum Co. had sold the chemical boron carbide to two prime contractors that were building nuclear reactor cores. Rickover said the company had made a 25% profit on these sales. The GAO agreed...
