Title: Innovations of Jong-kyun Park in Reactor Safety

Introduction

Jong-kyun Park is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of nuclear engineering, particularly in enhancing the safety of pressurized light water reactors.

Latest Patents

One of his key patents is titled "Pressurized light water reactor having flow converting grooves for emergency core cooling water." This invention focuses on a direct vessel injection-type pressurized light water reactor (DVI-PLWR). The patent addresses the critical issue of emergency core cooling water (ECC) being directly injected into a downcomer of a reactor vessel. To mitigate the risk of ECC bypass during a cold leg guillotine break (CLGB), Jong-kyun Park's design incorporates a series of V-shaped corrugations arranged vertically around the pressure vessel and core barrel. These grooves effectively phase-separate the ECC from high-speed lateral fluid flow, allowing the ECC to stagnate and flow down to the lower section of the downcomer due to gravity. This innovative approach significantly enhances the thermal hydraulic safety of the reactor during large break loss-of-cooling water accidents.
