核电站防甩支架承受力估算实例分析

Anti-Swing Bracket Tolerance Estimation Example Analysis for Nuclear Plant

核电设计中需要考虑高能管道发生破裂事故对周围重要核级物项的影响,设计中常采用设置防甩支架的措施使事故影响降低到最小化,防甩支架承受力一直是管道设计者难以解决的问题之一。笔者基于多年的设计经验,根据能力守恒的原理及材料本身的力学性质,总结出一种可用于核电站实际设计使用的核电站防甩支架承受力估算方法,并以M310堆型工程中的实际防甩支架为例,详细讲解如何使用这种估算方法来计算防甩支架的受力,通过这种估算方法可以略加保守地解决工程设计中的计算问题。结果表明,这种方法是安全可靠的。

Considering the effects of high energy pipeline rupture accidents on the surrounding important nuclear grade items, we often use anti-swing bracket measures in design to minimize accident influence. Anti-swing bracket tolerance is always a problem for tube design. Based on experience for many years, we use principle of conservation of energy and material mechanical properties to calculate anti-swing bracket tolerance estimation method for nuclear plant design. Then, taking anti-swing bracket of M310 reactor as example, introduce how to use this estimation method to calculate anti-swing bracket tolerance in detail. Use the estimation method can slightly conservative solve calculation problems in engineering design, this method is safe and reliable.
