摘要
压水反应堆首次启动过程中,通常需通过汽轮机甩负荷至厂用电、汽轮机打闸、汽轮机阶跃或线性降负荷等瞬态试验来验证事故状态下,反应堆的自动控制能力。核电厂运行通常是"堆跟机"模式,二回路负荷下降必然导致一回路功率下降。M310机组下,该瞬态试验导致R棒组先于功率控制棒下插,此后随着功率控制棒下插,R棒组会迅速提升并有可能提升至堆顶并保持一段时间,使反应堆失去温度控制能力。利用反应性平衡方程可以得到此段时间内反应性变化,进而可以通过人为引入反应性来控制R棒组的提升或插入棒位,保证瞬态试验后反应堆的安全运行。
In order to verify the ability of automatic control of Reactor in an accident,We usually need to do some transient tests,such as loading rejection of Turbine to auxiliary power,Turbine tripping,Turbine step or linear load reduction,during PWR first starting.Nuclear power plant operation is usually adopted "reactor with turbine" mode,so decline of Turbine power will inevitably lead to a decline of reactor power.The transient Test of Reactor Transient test lead R rods inserted before power control rods,then the R rods will move up quickly and they may be raised to the top of the Reactor and remain for some time with the power control rods inserted,the consequence of that is reactor lost the ability to control its temperature.We can get the reactivity changes during this time with the reaction balance equation.Thus we can control the R bar group Lift or insert position through introduce a reactive artificially to ensure reactors are safe after transient tests.
