Abstract

Abstract

Seismic design is an important part of nuclear facilities design to meet the comprehensive requirements of safety and economy. At present, the seismic design of research reactors lacks corresponding specifications and studies, and a relatively complete method system has not yet been found. In this paper, a seismic design method for class II research reactor matching structure and equipment is recommended. Taking the earthquake motion with a 50 a exceedance probability of 2% as the safe shutdown earthquake (SSE), and taking the 2 MW liquid fuel thorium based molten salt experimental reactor (TMSR-LF1) as an example, the design response spectra obtained by using this method and various specification methods are compared and analyzed, and they are applied to the seismic design and calculation of structures and equipment. The results show that the recommended method has better economy than the nuclear power code and better conservatism than the civil code on the premise of meeting the seismic design matching of structures and equipment.
