Abstract

The designs and analyses of the diagnostic port plug for installing diagnostics have been carried out from various aspects in order to advance the port plug concept to the realistic design. Manufacturing processes have been studied for the alternative structure using the rolling plates and ribs, in addition to the reference structure using forging material. Electromagnetic loads onto the upper port plug during a vertical displacement event have been evaluated. It has been shown that maximum moments are about half of the reference ones. The design integration of three diagnostics into one of the upper port plugs has been performed by considering required aspects such as diagnostic functions, neutron shielding, maintenance of diagnostic components and cooling channels.
