In response to the national call for the independence of nuclear power construction,OVM organized a full-scale vertical steel beam grouting test for nuclear power plant containment. The test was carried out in combination with the grouting of prestressed containment system in Fangjiashan, Qinshan and Fuqing nuclear power plants. This paper mainly introduces the purpose, program, process and results of the test under the condition that all the equipment is made in China. The test results show that the use of domestic anchors and equipment can meet the requirements of vertical grouting of prestressed channels in nuclear power containment, and has far-reaching significance in promoting the autonomy of nuclear power engineering construction in China
