Abstract

Abstract

In order to improve the seismic performance of ZH-65 steam generator of HPR 1000 nuclear power plant, a new support scheme of steam generator is put forward, that is, the structure of connecting rod and hydraulic damper is used for the upper support of steam generator, and the overall design scheme and the thermal expansion compatibility of connecting rod are designed and studied. Compared with the original steam generator upper support of the second generation plus nuclear power unit, the upper support designed and studied in this paper is greatly optimized in terms of equipment weight, number of welds and difficulty of installation and commissioning; It can effectively reduce the supporting load, and the maximum reduction range is about 24%; The weld load of steam generator nozzle can be reduced, and the maximum reduction range is about 28%.
