某核电厂排水口消能设施优化研究

Study on Optimization of Energy Dissipation Facilities at Outfall of Nuclear Power Plant

本文以某核电厂排水口为研究基础,通过物理模型试验对消能坎、消力墩、消力池、护底混凝土板等多种消能和防冲刷设施的不同组合、不同布置形式及不同的尺度进行优化分析研究,从而形成核电厂排水口消能设施方案。通过试验可知,在排水口内设置消力墩、提高尾坎高度,使得水流在排水口内尽量充分消能,能够达到分流、扩散、消能的效果,有效防止排水口附近区域的冲刷。试验成果可为类似核电厂或火电厂等排水口防冲刷工程提供参考。

Based on the outfall of one nuclear power plant,physical model tests are carried out to analyze the effect of different combinations,layout forms and scales of such energy dissipation and anti-scouring facilities as energy dissipation curb,block,basin and concrete bottom-protective slab,which leads to final plan of energy dissipation facilities at outfall of the nuclear power plant.The test results show that the arrangement of baffle block and the increased height of energy dissipation curb dissipate energy of water flow before the outfall as much as possible,which achieves split-flow,diffusion and energy dissipation,and effectively prevents the area near the outfall from scouring.The research can provide a reference for similar anti-scouring works at the outfalls of nuclear power plants or thermal power plants.
