There are many equipments important to safety in - vessel of cefr , such as intermediate heat exchanger , decay heat exchanger , primary coolant pump , and core support structure 其堆內(nèi)有許多涉及反應(yīng)堆安全的重要部件,如中間熱交換器,事故熱交換器,一次主循環(huán)鈉泵以及堆內(nèi)支承等。
3 ) . the flow velocity and temperature change rapidly in hot plenum under the transient condition such as in the case of reactor scram condition . thermal stratification phenomena will be observed nearby the inlet of intermediate heat exchanger 在事故停堆后的瞬態(tài)分析中,熱鈉池的流場(chǎng)和溫場(chǎng)變化劇烈,并在中間熱交換器的入口附近形成穩(wěn)定的熱分層。
