对200 MW核供热堆装载模式(燃料组件布置、可燃毒物棒根数和可燃毒物质量分数配置)进行了优化.利用模拟退火算法和先进格林函数节块法进行多步燃耗优化计算.引入敏感性系数,并通过敏感性分析的方法决定优化参数,因此在单目标和多目标优化时均取得了明显的效果.对组件布置和可燃毒物质量分数的优化计算结果表明,在不改变原有的富集度和组件类型的前提下,与参考值相比,优化后的循环长度、功率峰因子和卸料燃耗均有明显的改善.该燃料管理方法不仅可用于低温堆而且也可以推广到压水堆.

·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for *** was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes ***,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.
