在中子通量下和/或与初级冷却剂接触的设备的材料库存摘要对于辐射防护设计非常重要，这涉及到在维护期间可被堆芯中的中子激活并有助于职业辐射照射(ORE)的元素。反应堆冷却剂系统(RCS)组件中钴基堆焊部件的数量和残留钴含量必须根据在设计阶段应用的ALARA(尽可能低)方法来证明是合理的。本文提供了一些元素，证明根据™方法，关于材料库存的EPR ALARA设计将导致矿石含量较低。
Summary Material inventory of equipment under neutron flux and/or in contact with primary coolant is of great importance for radiation protection design, regarding elements which can be activated by neutrons in the core and contribute to Occupational Radiation Exposure (ORE) during maintenance. The amount of Cobalt-based hardfacing parts and the residual Cobalt content in components of the Reactor Coolant System (RCS) have to be justified according to the ALARA (As Low As Reasonably Achievable) approach applied at the design stage. This paper provides elements which demonstrate that the EPR™ design regarding material inventory will lead to a low ORE, in accordance with the ALARA approach.
