Swiss nuclear material stocks abroad

Since the entry into force of the Nuclear Energy Act (SR 732.1, KEG) and the Safeguard Ordinance (SR 732.12), all nuclear material stocks abroad that are owned by Switzerland have to be reported annually to the supervisory authorities (Art. 18 Safeguard Ordinance). Nuclear material owned by the operators of the Swiss nuclear plants is located in Germany, France, the UK, and Sweden. The changes in stocks result from the procurement and processing of uranium into fuel elements; these depend on economic and operational requirements. The Federal Office of Energy publishes these stock figures.自《核能法案》（Nuclear Energy Act，SR 732.1，KEG）与《保障条例》（Safeguard Ordinance，SR 732.12）正式生效以来，瑞士所有境外持有的核材料库存均需依据《保障条例》第18条的要求，每年向监管机构报备。瑞士核电厂运营商所持有的核材料分布于德国、法国、英国及瑞典境内。库存变动源于铀的采购以及将铀加工为燃料元件的流程，其变动受经济与运营需求的影响。联邦能源办公室（Federal Office of Energy）会对外公布此类库存统计数据。
