摘要
介绍压水堆铀燃料元件加工设施的核安全审评原则、审评要点和审评实践。审评原则包括:基本原则,工程原则和管理原则。审评要点包括:UF_6泄漏,核临界和火灾爆炸。这三种事故无论发生哪一种都将会造成不同程度的放射性物质的释放或产生辐射危害。针对宜宾核燃料元件厂扩建工程的实际情况,除上述三个要点以外,由于通风系统存在缺陷,导致某些UO_2粉末发尘的岗位空气中的铀浓度偏高也列入重点审评范围。
Safety assessment principles, assessment points and review practice of fuel fabrication facil ity for PWR are introduced. Safety assessment principles include basic principles, engineering principles and management principles. Assessment points include: UF_6 leakage, nuclear criticality, fire and explo sion. Any accident happened mentioned above will lead to radioactive material release in different levels or make emission damage. As for Yi Bin fuel fabrication plant (YFP), it should be included in main as sessment that aerosol concentration in some UO_2 powder process posts are higher than the design value ex cept above mentioned assessment points because there are some shortcomings in ventilation system.
