  • The aim of this study is to suggest design requirements on the military barriers which are installed to reduce critical damage on protective facilities against sudden pin-point attacks caused by North Korean artilleries. For this purpose, site investigation and review of design drawings associated with barriers built in the contact areas are conducted. With identified data concerning barriers, the geometric modeling, which is used in the structural analysis, is performed. And then, the possible threat of North Korea is determined based on intelligence preparation of battlefields. Once the structural modeling and threat analysis are completed, structural damage on barriers and protective facilities are assessed in terms of impact, penetration, scabbing, and blast pressure effects. According to the analysis results, the thickness of barriers should be 450mm at least and current established barriers need to be structurally reinforced via sectional enlargement.

  • This study covers securing legal systems and institutions regarding the standards for installing fire prevention facilities to prevent fire on wooden architectural heritage. Conflicts among relevant laws were revealed and problems related to fire prevention performance, technical standards, responsibilities, etc. in the process of establishing legal fire prevention equipment and the equipment for self-extinguishing were identified through pondering over current legal systems of fire prevention facilities. To resolve the problems, at least the principle to preserve original shapes of wooden architectural heritage should be secured even though fire prevention facilities are installed and the installation process should be regulated by laws considering features of fire on wooden architectural heritage so that fire prevention performance can be guaranteed. The directions to improve installing system through legalization of design, construction, and audit review institutions and legalization of the technical standards for fire prevention facilities were suggested to guarantee performance when establishing fire prevention facilities for wooden architectural heritage.

  • 원자력시설 등의 방호 및 방사능 방재 대책법에 따라 2018년 개정된 설계기준위협(DBT)은 전자적 침해행위 중 하나로 의도적 전자기파 간섭(IEMI) 위협을 반영하였으며, 이에 따라 원자력시설은 IEMI 위협에 대한 물리적방호시책을 마련하여야 한다. 한국원자력통제기술원(KINAC)은 개정 설계기준위협에 따라 2018년 원자력시설의 고출력 전자기파 방호 심·검사 기준(KINAC/RS-020)을 개정하여 원자력시설의 IEMI 위협에 대한 취약성 평가 방법론을 제시하고 있다. 본 논문은 KINAC/RS-020에 따른 원자력시설 IEMI 위협 취약성 평가를 위해 개발 중인 IEMI 위협에 대한 시나리오 평가 방법론에 대해 소개한다.

  • This study is a study on influencing factors to derive considerations when establishing a large drone integrated protection system targeting important national facilities. Currently, drone protection is implemented by piecemeal installation of drone protection equipment developed on the market in response to the needs of government agencies, the military, and national important facilities. For this reason, there is a waste of resources, such as duplicate installation or overlapping operation of equipment, and institutional and legal problems between operations are emerging. Accordingly, we sought to identify factors influencing the establishment of an efficient and systematic anti-drone protection system targeting national important facilities. Considering the research purpose and scope, this study derived 3 influencing factors and 12 detailed influencing factors through case analysis, protection theory research, and analysis of related laws. If the results of this study are used as considerations when building an integrated anti-drone protection system in the future, all national defense elements will be integrated and systematic integrated anti-drone protection will be possible according to their respective roles. In addition, it will provide a theoretical foundation for building an integrated anti-drone protection system. The results of this study are valuable in that they present logical and systematic influencing factors for establishing an integrated anti-drone protection system.

  • Two test standards to be applied for evaluating shielding effectiveness of HEMP protection facilities, MIL-STD-188-125-1 and IEEE std. 299, provide different test results in spite of the same facility. In particular, at the frequency range of 10 kHz~20 MHz, it is confirmed that the test results by the IEEE Std. 299 are about 20~30 dB lower than the evaluated results by MIL-STD-188-125-1. These results are due to the different measurement conditions specified in the two test standards. Therefore, IEEE Std. 299 can be applied for the shortening of test distance, but the required SE performance based on MIL-STD-188-125-1 must be modified.

  • 방사능방재법의 개정을 통해 전자적 침해행위의 유형으로 고출력 전자기파(Electromagnetic Pulse, 이하 EMP) 위협에 대한 대책이 원자력시설별로 마련되도록 요구되었다. 그동안 국내의 EMP 위협에 대한 방호 대책은 군사시설 중심으로 오랫동안 연구되고 적용된 바 있으나, 공공 및 민간시설에 대해서는 이제 막 첫발을 내딛은 상황이다. 본고에서는 한국원자력통제기술원 사이버보안실에서 추진하고 있는 국내 원자력시설에 대한 EMP 방호 규제체계 구축현황에 대해 소개하고, 이에 배경이 되는 법적 근거 및 국내 외 유관 연구사례 및 기술표준 등에 대해 살펴보고자 한다.

  • 경·중수로 연계 핵연료 주기 (Direct Use of Spent PWR Fuel in CANDU : DUPIC ) 기술개발의 핵물질 보장조치(Safeguards)는 경수로 사용후 핵연료를 중수로에 재 활용하기 위한 DUPIC 공정에 대한 최적 보장조치 시스템을 구축하여, 국제 원자력 기구(IAEA) 및 국제 원자력 사회에서 핵 투명성확보 및 신뢰도를 향상시키는 것을 기술개발의 목적으로 하고 있다. DUPIC 공정은 고립된 차폐시설내의 고준위 방사선장 하에서 가동되므로 타 시설에 비해 핵 물질 전용 가능성은 희박하지만, 전 공정이 원격제어 되야 하고, 조업조건이 정복해야 하므로 기존의 보장조치 기술보다 더욱 발전된 계량관리시스템, 측정시스템 및 감시시스템 등을 개발하여야 한다. 이를 위해 본 연구에서는 각 항목에 대한 요소 분석 및 각 항목별 향후 연구방향에 대해 분석하였다. DUPIC 공정 전반에 대한 핵물질 계량관리를 위해 물질수지구역 (Material Balance Area : MBA) 및 주요측정 지점 (Key Measurement Point : KMP )을 설정하여 각 측정지점별 측정방법 및 재고검증(Inventory Verification) 방법을 분석하였다. 최적 측정시스템을 개발하기 위해 적용 가능한 비파괴분석 방법들을 분석한 결과, 핵분열성 물질 함량을 정량적으로 측정할 수 있는 수동적 중성자 측정법이 가장 적합하다는 결론을 얻었다. 또한, 감시시스템을 개발하기 위해 전용전략의 주요 요소 및 전용경로 등을 분석하였으며, 핵물질 및 시설에 대한 물리적 방호체제를 DUPIC시설에 적용하기 위하여 물리적 방호에 필요한 방호체제 요소를 분석하여 DUPIC 시설을 위한 가상적인 방호체제를 구축하였다.

  • Recently there are increasing number of claims that it is necessary to build a countermeasure in case of aggressive threats by small drones. During Russia-Ukraine war ignited by Russian invasion on February 2022, attacking drones have been being used widely to damage other country's national major facilities. On December 2022, 5 drones sent by North Korea made a flight around Seoul, South Korea about 7 hours, but it was not successful to search and track them. Furthermore, none of these were destroyed and shot down. Counter-drone system is essential system to search and identify unintended small drones and disable them. This paper is for proposing required functions for building a counter-drone system for national major facilities. We conducted focus group interviews with relevant government officials and analyzed their suggestions on how to augment protection capabilities to defend against small drone attacks.

  • Protective facilities are the last means of ensuring the survivability of personnel and assets, and there is a greater amount of matters to consider than those of general buildings. However, the Defense Military Facilities Criteria and the Ministry of the Interior and Safety, Ordinance No. 20, are only considering the expected enemy threats. In this study, we use objective and statistical methods to refine the consideration of the required capacity of protection based on the opinions of the experts. Specifically, the study adopts the Delphi technique associating the experts related to 30 defense military facilities criteria. The first-round questions were open-ended, and it compiled the points to consider related to the bulletproof and explosion - proof design. The second questionnaire was applied as closed questionnaire with 7 points scale methods. As a result of the factor analysis on the opinions of the experts, it was confirmed that the protection requirement level was due to METT + TC.
