[en] The report treats the feasibility of safeguarding a wide-scale domestic mixed oxide industry. It presents the results of an effort originally undertaken as part of the GESMO environmental impact statement and is being published as a technical report in order to provide information which would otherwise be unavailable due to the termination of the GESMO activity. The characteristics of a projected wide-scale MOX industry, the perceived threat to that industry, and the possible consequences of sabotage or theft of nuclear material are discussed. Safeguards strategies, technical approaches, and currently existing safeguards requirements and their applicability to safeguarding a MOX industry are discussed and their economic costs and societal impacts assessed
