To make it worse, due to malfunction of Isolation Control Valves in AFWS (Auxiliary Feedwater System), the supply of cooling water to SGs (Steam Generators) was delayed approximately 8 minutes compared to AOP (Abnormal Operating Procedure) . In the long run, on account of deferred heat sink provision to SGs, the reactor core was melted partially. It was the first critical accident in the US commercial NPP (Nuclear Power Plant) history. Hence, after TMI Accident, US NRC (Nuclear Regulatory Committee) suggested more than one hundred alternatives to improve safety and reliability of NPP. Among these countermeasures, one proposal was related to training area. It was SAT (Systematic Approach to Training) methodology. Therefore, the goal of SAT is the enhancement of NPP stability through training point of view. Since the appearance of SAT in the nuclear industry, it has acquired the unwavering position in the US NPP training field. Meanwhile, significance of NPP decommissioning has been soared up in South Korea since the announcement of Kori Unit-1 decommissioning decision. According to the proclaimed plan from Korean government, Kori Unit-1 is scheduled to be decommissioned from June, 2017. Under this circumstance, nurturing sufficient number of NPP decommissioning engineers is one of the most urgent issues in South Korean nuclear industry. Hence, to elevate efficiency and consistency of training quality, SAT methodology can be a reliable solution for the training of decommissioning engineers. For this reason, the present study aims to design SAT based NPP decommissioning engineer training in South Korea.  \nKey words: Systematic Approach to Training, nuclear power plant, decommissioning, US nuclear regulatory committee, Three Mile Island Unit-2 .  \n1. Introduction  \nGenerally speaking, operation, maintenance and oversight of NPPs (Nuclear Power Plants) which are equipped with a great number of mechanical equipment, electrical devices and gauging instruments require sophisticated and sensitive approaches, intrinsically. Hence, to prevent unexpected events or accidents in NPP which are originated from complexity, a variety of proactive methods have been taken into consideration since the first commercial NPP located in Calder Hall, the United Kingdom. Among diverse trouble preventative ways, training has played one of the most significant roles to reinforce safety and reliability of NPP. This is the reason why  \nCorresponding author: Jeong Keun Kwak, M.S., senior manager & instructor, research field: decommissioning of nuclear power plant.  \nnuclear industry in every country has established and maintained its own training methodologies and institutes.  \nAfter TMI Accident, which was the first severe accident in the world commercial NPPs before the Chernobyl case, there were more than one hundred proposals to enhance durability and stability of NPP by the USNRC (United States Nuclear Regulatory Commission) . In submitted suggestions, one proposal was related to personnel training in NPP which was SAT (Systematic Approach to Training) . And this methodology was adopted in the US NPP industry, immediately. Since then, SAT has been the unwavering fundamental guideline in the field of NPP employee training in the US.  \nIn South Korea, since the announcement of Kori Unit-1 shutdown in June 2015, NPP decommissioning  \nSystematic Approach to Training for Design of Nuclear Power Plant Decommissioning Training 15  \nhas been ","cbCaib1QtxeUVF2l","https://ap.wps.com/l/cbCaib1QtxeUVF2l","pdf",245676,"English","# Introduction\n## Background and motivation from TMI and U.S. NRC proposals\n## Need for SAT-based decommissioning training in South Korea\n# Systematic Approach to Training\n## ADDIE structure for SAT","[{\"question\":\"What training methodology does the study propose for decommissioning engineers in South Korea?\",\"answer\":\"The study proposes a Systematic Approach to Training (SAT) based design for nuclear power plant decommissioning engineer training.\"},{\"question\":\"Why is SAT considered significant for nuclear power plant training in the context of safety reliability?\",\"answer\":\"After the Three Mile Island Unit-2 accident, U.S. NRC suggested many alternatives, including a proposal related to training.
