采用RELAP5/SCDAP/MOD3.4程序对医院中子照射器I型堆(IHNI-1)在事故工况下的瞬态特性进行研究,对意外大反应性引入和池水丧失事故工况进行了计算和分析,计算结果表明:IHNI-1堆具有良好的固有安全性,在发生大反应性引入和池水丧失事故时,最终能够稳定在较低功率,确保反应堆安全。
RELAP5/SCDAP/MOD3.4 is used to simulate and analyze the transient proceeding of in-hospital neutron irradiator mark 1(IHNI-1) reactor in accident condition.Large reactivity insertion accident and loss of coolent of pool accident are calculated and analyzed.The results show that IHNI-1 reactor is characterized with inherent safety. The negative coolant temperature feedback limits the nuclear power to an stable level and the reactor is safe under the accident.
