Abstract

The canned motor pump is a device in one of the most important loops in the nuclear power
plant system and key technology research project, of which the seismic requirements shall be
checked by Category A. It is required that the structural integrity and electric drive assembly
performability of the unit can be ensured during or after operating basic earthquake (OBE) or safe
shutdown earthquake (SSE). The author uses Ansys software workbench module to carry out
appearance-based three-dimensional modeling, finite element meshing, intrinsic mode analysis,
and carry out structural overall element analysis and calculation considering dead weight load and
earthquake spectrum load. The results show that the unit major structure rotary and static parts,
gear system, bearing parts, bolt and screw strengths meet the requirements and the structure
maintains integrity, the relative deformation of the unit rotary and static parts shall be less than the
specified value of gap among them, so as to keep the performability and not interfere with the
operation. The appearance–based seismic analysis method not only can ensure the calculation
accuracy, but also can greatly reduce the workload in calculation and checking, has a certain
learning value.
