...Equally pressing is the problem of permanent storage for lethal radioactive wastes contained in spent reactor fuel elements. The practice now is to dissolve the fuel rods in nitric acid, then store the liquid in vats underground. Already the AEC has more than 80 million gallons of this lethal liquid (which includes wastes from weapons production) In tanks that must be constantly cooled and scrupulously maintained for hundreds of years before the radioactivity is spent. The AEC is now perfecting ways to solidify the wastes to permit storage in underground caverns. Even so, the growth of nuclear power could make...
...overtakes Cambridge this time of year will be attributed once again to a subtle combination of Spring and hour exams. But the real reason for that feeling of being "unaccountably pooped," says Dr. John T. Middleton, a leading expert on air pollution, is a common air pollutant known as nitric oxide...
Reacting with sunlight and other common air contaminants, nitric oxide forms ozone, a chemical which closes part of the lungs and forces an animal to use more energy to get enough oxygen. Middleton showed other experts at a two-day conference at the New York University School of Medicine last week how ozone "in the quantities you commonly find in New York city air" slows down rats and mice when they exercise on a treadmill...
...crucial time of the final semester approaches, the administration should take effective measures to eliminate this pernicious deterrent to serious study. Harvard scarcely deserves to criticize the Commonwealth if it cannot maintain the purity of its own air. The movement to eradicate Nitric Oxide must begin at home...
...Agena's problems began 368 seconds after launch. At that moment, precisely on schedule, fuming nitric acid fuel began spraying into the rocket's thrust chamber, followed a few milliseconds later by the oxidizer, unsymmetrical dimethylhydrazine. Somehow, too much fuel entered the chamber ahead of the oxidizer. The result was a "hard start" of the Agena's engine, similar to the backfire that occurs when gasoline and air ignite prematurely in an automobile engine...
