本文讨论了一项以成本/效益为导向的评估结果，该评估与先进小型模块化反应堆（smr）的应急规划区（EPZs）的规模有关。适当规模的加工区可以为SMR许可商节省大量成本。美国核管理委员会和其他组织发表的论文讨论了当前应急准备监管要求对小型反应堆的适用性，包括确定适当的EPZ规模。美国核管理委员会和工业界都认识到，应该开发一种方法来确定适合小型反应堆的EPZ规模。如本文所讨论的，设想用于小型综合反应堆的小型出口加工区的相对成本已经进行了定性评估。在之前论文的基础上，本文对EPZ规模的场外应急计划成本进行了定量的成本/效益评估，与目前美国核电厂的成本相比，小型反应堆的应急计划成本可能是合理的。该评估确定，使用较小EPZ的被许可方可以在SMR的名义40年使用寿命期间大幅节省场外应急计划成本。这种以成本/效益为导向的评估表明，在典型的单机组核电站40年的寿命期内，将羽流暴露路径EPZ从10英里减少到场址边界，可以将场外应急计划相关成本降低90%以上。«少
This paper discusses the results of a cost/benefit-oriented assessment related to sizing of the emergency planning zones (EPZs) for advanced, small modular reactors (SMRs). An appropriately sized EPZ could result in significant cost savings for SMR licensees. Papers published by the U.S. Nuclear Regulatory Commission and other organizations discuss the applicability of current emergency preparedness regulatory requirements to SMRs, including determining an appropriate EPZ size. Both the NRC and the industry recognize that a methodology should be developed for determining appropriate EPZ sizing for SMRs. Relative costs for smaller EPZs envisioned for SMRs have been assessed qualitatively as discussed in this paper. Building off the foundation provided in the earlier papers, this paper provides a quantitative cost/benefit-oriented assessment of offsite emergency planning costs for EPZ sizes that may be justified for SMRs as compared to costs typically incurred for the current fleet of U.S. nuclear power plants. This assessment determined that a licensee utilizing a smaller EPZ could realize significant savings in offsite emergency planning costs over the nominal 40-year lifetime for an SMR. This cost/benefit-oriented assessment suggests that a reduction of the plume exposure pathway EPZ from 10 miles to the site boundary could reduce offsite emergency planning relatedmore » costs by more than 90% over the 40 year life of a typical single unit nuclear power plant.« less
