Structural Integrity Evaluation for Overhead Crane of a Research Reactor

The purpose of this document is to confirm the structural integrity of overhead crane through the numerical simulation. The analysis results of overhead crane are evaluated with design limits of the KEPIC MCN Codes and Standards. The main function of overhead crane is to handle the fuel assembly, reactor components, and utilization facilities in the research reactor. The overhead crane as a double girder type crane system is classified into safety class NNS (Nonnuclear Safety) and seismic category II. The structural integrity evaluation for the crane is performed by using response spectrum analysis. The analysis results show that the maximum stresses of the crane under the seismic loads is within the KEPIC Code limits. Thus, the validity of the present design of the overhead crane has been demonstrated.
