实验快堆的设计,必须具有非能动安全特征,这是近几年来在核反应堆设计中明显的新进展。我们所设计的池式实验快堆,在事故初期因钠池热容量大及堆芯的各种负反应性反馈,本身就具有一定的固有安全性。然而衰变热的排出最终要由排出系统来实 The design of experimental fast reactor must have passive safety features, which is a clear new progress in the design of nuclear reactors in recent years. In the early days of the accident, the pool-type experimental fast reactor we designed had some intrinsic safety due to the large thermal capacity of the sodium pool and various negative reactivity feedbacks of the reactor core. However, the decay heat is ultimately discharged by the discharge system
