俄罗斯VVER-1000/V428堆型是在总结VVER-1000/V320型机组的设计、建造和运行经验基础上,集精确自动控制,非能动安全先进技术和西方第三代反应堆控制系统为一体的改进型堆型。田湾核电站3、4 号机组为VVER-1000/V428堆型,采用“自主调试”的模式,即由田湾核电站营运单位—江苏核电有限公司全面负责3、4 号机组的调试...
This paper presents the results of thermal-hydraulic calculation of “Steam Line Break” analysis at full power reactor for VVER-1000/V320 units at Kozloduy Nuclear Power Plant (KNPP), done during the development of symptom based emergency operating procedures (SB EOPs) for this plant. The RELAP...
model for VVER-1000/V320 NPP are included: reactor vessel; core region represented by three channels; pressurizer system includ- ing heaters, spray and relief valves; safety system–low pressure injection pumps. In the model also is presented a make up/drain ...

Despite similarity between VVER-1000/V320 and PWR, accounting of specificities of Russian reactor designs is still required. Part of it is the simulation of core decay heat rate after the shutdown. MELCOR 1.8.4 distinguishes fifteen classes. Each of them contains chemical elements with similar ...
