封记作为一种核材料控制手段,可与核材料衡算互为补充。封记主要用于标识已核查过或被封存的物料与设备,以保证核材料衡算信息的完整性和连续性,提高现场核查的效率。本工作对构成封记系统的3个重要要素,即封记设备、封记管理以及封记的信息支持系统进行了研究。研制出了带有条 As a nuclear material control measure, seals can complement each other with the accounting of nuclear materials. The seal is mainly used to identify the materials or equipment that have been checked or sealed to ensure the integrity and continuity of accounting information of nuclear materials and enhance the efficiency of field verification. In this work, we study the three important elements of the seal system, namely the seal equipment, seal management and seal information support system. Developed with a bar
