A bill to prevent the proliferation of nuclear weapons by limiting the transfer of certain nuclear technology and materials.

Provides that, unless the President determines that the national security requires a license or authorization, and makes a report of such determination to the Congress (which report shall be available to every Member of the Congress) at least sixty days prior to the issuance of such license or authorization, the Nuclear Regulatory Commission shall not license or otherwise authorize any export, and the Energy Research and Development Administration shall not make or permit any export, of nuclear fuel or nuclear technology: (1) to any country which furnishes or agrees to furnish uranium enrichment or nuclear fuel reprocessing plants to a country not a party to the nuclear nonproliferation treaty; or (2) to any country which is not a party to the nuclear nonproliferation treaty and which develops either an enrichment or reprocessing plant without concluding an agreement with the International Atomic Energy Agency or Euratom by which all present and future nuclear facilities are made subject to safeguards established by either such agency against diversion of nuclear material.
