摘要
文章基于AP1000蒸汽发生器(SG)自然循环试验,对SG在自然循环工况下带走堆芯衰变热的能力进行了评估和分析。通过评估和分析AP1000 SG自然循环试验方法和验收准则,研究试验过程中电厂响应的主要参数,利用LOFTRAN程序模拟SG自然循环试验过程进行对比分析,验证了堆芯衰变热能够通过蒸汽发生器自然循环带出,SG自然循环功能能够保证堆芯的安全,这对于论证AP1000设计的有效性和可靠性至关重要。
The heat removal capacity of AP1000 steam generator(SG)is evaluated and analyzed based on the AP1000 SG natural circulation test.Through analyzing the method of SG natural circulation test and researching the main plant data during the test process and comparing with the LOFTRON calculating result,the conclusion is demonstrated that the reactor core fission product decay heat can be removed by the steam generator under the conditions of natural circulation.It is also verifie d that the SG natural circulation can ensure the reactor core safety.It is very important to demonstrate the AP1000 design availability and reliability.
