From the Declaration presented to Congress and the President of the United States on the 30th anniversary of the atomic bombing of Hiroshima and signed by more than 2,000 biologists, chemists, engineers Since the proclamation of the scien­ and other scientists. . " . . . the country must recognize that it now appears imprudent to move tist's declaration, some of our objec­ forward with a rapidly expanding nuclear power plant construction program. The risks of doing so are altogether too greal We, therefore, tives have been achieved. urge a drastic reduction in new nuclear power plant construction starts before major progress is achieved in the required research and in resolving present controversies about safety, waste disposal, and plutonium safeguards. For similar reasons, we urge the nation to suspend its program Since 197 5, plans for 60 reactors have of exporting nuclear plants to other countries pending resolution of the national security questions associated with the use by these countries of been cancelled, one-quarter of the total the by-product plutonium from United States nuclear reactors." then planned.
