THE PAPERS, SUMMARIES, AND DISCUSSIONS FORM THE SYMPOSIUM INDICATE THE STATE OF THINKING ON THE OVERALL SAFEGUARDS PROBLEM AND VENTURE INTO RELEVANT AREAS THAT HAVE RECEIVED RELATIVELY LITTLE ATTENTION IN THE PUBLIC FORUMS. THE DISCUSSION CONCENTRATES ON ASPECTS OF DEVELOPING IMPORTANCE TO THE SAFEGUARDS PROBLEM AND ITS SOLUTION. THE GOAL OF LASTING INTERNATIONAL PEACE REQUIRES DEDICATED EXPERTS COMMITTED TO THE APPLICATION OF FEASIBLE CONTROLS ON NUCLEAR MATERIALS. SUCH CONTROLS MUST NOT DEPRIVE NATIONS OF THE OPPORTUNITY TO USE NUCLEAR ENERGY TO BENEFIT THEIR PEOPLE, BUT THEY MUST PREVENT THE CLANDESTINE MANUFACTURE OF NUCLEAR EXPLOSIVES. ANTIPROLIFERATION PROGRAMS REQUIRE A MULTIFACETED APPROACH USING PHYSICAL AND DESIGN SECURITY SYSTEMS, COORDINATION OF POLICE AGENCIES, AND ADAPTATION OF PROPOSALS FROM THE INTERNATIONAL ATOMIC ENERGY AGENCY. DISCUSSION OF NATIONAL AND INTERNATIONAL SAFEGUARDS SYSTEMS REVEALS THE APPREHENSION OF REGULATORY AGENCIES TOWARDS BARGAINING WITH INDUSTRIES AND GOVERNMENTS; ALTHOUGH COOPERATION IS A REQUIREMENT OF SAFEGUARDS, IT SHOULD NOT RESULT IN WEAKENED SECURITY STANDARDS. PSYCHOLOGICAL STUDIES AND POLITICAL RESEARCH INVOLVING SIMULATIONS HAVE DEVELOPED MODELS FOR EXAMINING SAFEGUARDS SYSTEMS AND HAVE SHOWN THE EFFECT OF SOCIAL FACTORS ON PUBLIC POLICY DECISIONS. THEFT PREVENTION SYSTEMS, NUCLEAR DETECTION METHODS, AND FACILITY INSPECTIONS ARE DISCUSSED IN SPECIFIC PRESENTATIONS. TABULAR DATA, REFERENCES, AND A LIST OF PARTICIPANTS ARE PROVIDED.
