Meeting the Challenge

National and International activities affecting safeguards, which took place during the last year, are listed. The Institute activities for the same period are briefly reviewed. The view is presented that the problems of international proliferation and of possible terrorist attempts to misuse nuclear materials in the USA cannot be avoided by negative steps such as freezing international shipments or postponing the use of plutonium. These problems must be faced squarely. Institute members understand the nuclear risks and safeguards measures to reduce the risks to acceptably low levels.
