摘　　要：49-2游泳池式反应堆(简称49-2堆)已运行多年,运行安全是决定49-2堆寿命的最重要因素。本工作对制约49-2堆寿期的硬件因素进行分析,如池体混凝土老化、铝质池壁腐蚀、一次水管道腐蚀、石墨箱及石墨盒肿胀等,提出相应的监督、预防和维护等措施。结果表明,堆主体等在8度地震下安全,千年一遇洪水叠加溃坝的水位下反应堆安全,一次水管线和堆水池的腐蚀等老化情况可接受,因此49-2堆可继续安全运行。Safe operation is the most important factor to determine the lifetime of aged 49-2 swimming pool reactor. In this paper, the hardware factors of lifetime were analyzed, such as the pool concrete aging, corrosion of aluminum container and primary coolant system, and graphite swelling etc. , and then the corresponding measures such as surveillance, prevention and maintenance were purposed. The results show that 49-2 swimming pool reactor can continue to operate safely due to that container is safe under 8 degree earthquake, the reactor is safe on flood level of once per millennium, adding dam break, and the ageing condition of primary coolant system and container is acceptable.
