The regulatory periodic safety inspection system is one of the most important methods for confirming the safety of nuclear power plants and the defense in depth in nuclear safety is the most important basic means for accident prevention and mitigation. Recently, a new regulatory technology based on risk-informed and safety performance has been developed and used in advanced countries. However, since the domestic periodic inspection system is being used in the same way over 30 years, it is necessary to know how the inspection contributes to the safety confirmation of the nuclear power plants. In this study, the domestic periodic inspection system currently in use was analyzed from the perspective of defense in depth in nuclear safety. In addition, the analysis results were compared to the U.S. NRC's safety inspection system to obtain consistency and lessons in this study. As a result of analysis, the NRC's safety inspections were distributed almost evenly at the all levels of defense in depth, while in the case of domestic inspection, they were heavily focused on the level 1 of defense in depth. Therefore, it appeared urgent to improve the inspection system to strengthen the other levels of defense in depth in nuclear safety.

Recently, there has been demand for the convergence of IT (Information and communication Technologies, ICT) with defense, as has already been achieved in civilian fields such as healthcare and construction. It is expected that completely new and common requirements would emerge from the civilian and military domains and that the shape of war field would change rapidly. Many military scientists forecast that future wars would be network-centric and be based on C4I(Command, Control, Communication & Computer, Intelligence), ISR(Intelligence, Surveillance & Reconnaissance), and PGM(Precision Guided Munitions). For realizing the smart defense concept, IT should act as a baseline technology even for simulating a real combat field using virtual reality. In this paper, we propose the concept of IT-based smart defense with a focus on accurate detection in real and cyber wars, effective data communication, automated and unmanned operation, and modeling and simulation.

Currently, the delayed compensation system, which does not reflect the R&D characteristics of the defense industry, is being applied, causing problems such as worsening management of defense companies and delayed power generation. The purpose of this study is to contribute to the development of the defense industry and the efficient promotion of combat capability by studying the improvement plan of the delayed compensation system reflecting the R&D characteristics of the defense industry. The research analyzed the defense industry R&D characteristics, national R&D, delayed compensation rate, reduction and exemption procedures and existing studies. Further, the Delphi technique was applied based on the status of the delayed compensation and the analysis of the cause of delay. It has been studied that it is not appropriate to apply the 'manufacturing and purchasing' standard of commercial products to defense industry R&D where the latest technology is applied and the success is unclear. Four measures were drawn to prevent delays, including the selection of excellent technology companies, and three measures to reduce delay compensation and apply differentials for rational treatment in case of delays. Just as the defense industry R&D is carried out under the Defense Acquisition Program Act due to the nature of the R&D industry, the defense industry will develop if the delayed compensation system is improved to reflect the R&D characteristics of the defense industry, and it will contribute to the acquisition of an efficient and economic weapons system.

In order to respond to the ballistic missile threat of North Korea, the ROK military is constructing a multi-layered defense that can minimize the vulnerability of single-layered defense. Accordingly, it is necessary to study an operation plan which can maximize the intercept rate of a multi-layered defense system. And to study the operation plan of the Korean missile defense system, it must be considered that the operational environment of the Korean military and the effects of the strategic strike system. Therefore, this study proposes a simulation model that reflects the characteristics of the Korean missile defense system and analyzes four interceptor missile operation plans. The simulation result indicates that a high intercept rate can be achieved in various situations by comprehensively considering the ballistic missile threat estimate, interceptor missile reserve, and the strategic strike system effect.

It has been shown that the lack of sufficient defense industry cooperation between Korea and the US. The severe imbalance in defense trade between tow countries and Korea's weak defense industrial base has been a problem. This paper suggests the enhancement of defense industry cooperation with the US as a defense policy. The US policy has been changed to utilize the globalization of defense industries. The following cases were analyzed to show the policy change; The security of supply arrangement with 6 countries, the defense cooperation treaty with the United Kingdom and Australia. the defense Memorandum of Understanding with 23 countries, and the international cooperation with 8 countries for F-35 JSF program. Korea government needs to sign a defense MOU with U.S. and the defense industries are recommended to increase the opportunities of weapon system co-development and co-production. So that the Korea defense industry may improve competitiveness and to overcome the current weaknesses.
