In this thesis, the domestic and foreign legislative background and legislative process of the Serious Accident Punishment Act were reviewed, and the Serious Accident Punishment Act in Korea was reviewed. In 2022, more safety accidents occurred in the construction industry than in other fields, and in particular, the most deaths occurred in the 'fall' type. In April 2023, regarding two criminal first-instance trial cases, the courts all sentenced guilty, and in one case, the representative of the company(CEO) was sentenced to imprisonment and was arrested. In response, the management side expresses the opinion that the punishment is excessive and there is a concern that corporate management will shrink, while the workers side(Union) argues that the responsibility of the business operator or manager should be strengthened by heavier punishment. As a countermeasure to overcome rationally, we present a plan in terms of legislation and resolution process. In other words, we present a review of the amendment to the Serious Accident Punishment Act and the Court Organization Act. In addition, guidelines for the a safety and health system must be implemented, and if an accident occurs, it must be dealt with reasonably. As a result, safety accidents in the construction industry should drastically decrease and safety culture should be properly established.

To effectively and safely manage the radiation exposure to nuclear power plant (NPP) workers in accidents, major overseas NPP operators such as the United States, Germany, and France have developed and applied realistic 3D model radiation dose assessment software for workers. Continuous research and development have recently been conducted, such as performing NPP accident management using 3D-VR based on As Low As Reasonably Achievable (ALARA) planning tool. In line with this global trend, it is also required to secure technology to manage radiation exposure of workers in Korea efficiently. Therefore, in this paper, it is described the application method and assessment results of radiation exposure scenarios for workers in response to accidents assessment technology, which is one of the fundamental technologies for constructing a realistic platform to be utilized for radiation exposure prediction, diagnosis, management, and training simulations following accidents. First, the post-accident sampling after the Loss of Coolant Accident(LOCA) was selected as the accident and response scenario, and the assessment area related to this work was established. Subsequently, the structures within the assessment area were modeled using MCNP, and the radiation source of the equipment was inputted. Based on this, the radiation dose distribution in the assessment area was assessed. Afterward, considering the three principles of external radiation protection (time, distance, and shielding) detailed work scenarios were developed by varying the number of workers, the presence or absence of a shield, and the location of the shield. The radiation exposure doses received by workers were compared and analyzed for each scenario, and based on the results, the optimal accident response scenario was derived. The results of this study plan to be utilized as a fundamental technology to ensure the safety of workers through simulations targeting various reactor types and accident response scenarios in the future. Furthermore, it is expected to secure the possibility of developing a data-based ALARA decision support system for predicting radiation exposure dose at NPP sites.

The Korean nuclear industry developed the SPACE (Safety and Performance Analysis Code for nuclear power plants) code and this code adpots two-phase flows, two-fluid, three-field models which are comprised of gas, continuous liquid and droplet fields and has a capability to simulate three-dimensional model. According to the revised law by the Nuclear Safety and Security Commission (NSSC) in Korea, the multiple failure accidents that must be considered for accident management plan of nuclear power plant was determined based on the lessons learned from the Fukushima accident. Generally, to improve the reliability of the calculation results of a safety analysis code, verification work for separate and integral effect experiments is required. In this reason, the goal of this work is to verify calculation capability of SPACE code for multiple failure accident. For this purpose, it was selected the experiment which was conducted to simulate a Multiple Steam Generator Tube Rupture(MSGTR) accident with Passive Auxiliary Feedwater System(PAFS) operation by Korea Atomic Energy Research Institute (KAERI) and focused that the comparison between the experiment results and code calculation results to verify the performance of the SPACE code. The MSGR accident has a unique feature of the penetration of the barrier between the Reactor Coolant System (RCS) and the secondary system resulting from multiple failure of steam generator U-tubes. The PAFS is one of the advanced safety features with passive cooling system to replace a conventional active auxiliary feedwater system. This system is passively capable of condensing steam generated in steam generator and feeding the condensed water to the steam generator by gravity. As the results of overall system transient response using SPACE code showed similar trends with the experimental results such as the system pressure, mass flow rate, and collapsed water level in component. In conclusion, it could be concluded that the SPACE code has sufficient capability to simulate a MSGTR accident.

화학물질을 이용한 화학테러·사고는 국내·외에서 지속해서 발생, 시도되는 추세이다. 국내의 경우, 환경부 화학물질안전원에서 CARIS(Ver. 2018)를 화학테러·사고 발생지역의 피해 영향 범위 평가 용도로 제공하여 현장 대응에 활용하고 있다. 하지만 현행 CARIS는 실내, 지하 등과 같은 폐쇄된 공간에 대한 영향을 고려하지 못하여 현장에서 요구하는 정밀한 피해 영향 범위 평가 결과를 제공하는데 어려우며 제공되는 정보도 제한적이다. 본 연구에서는 CARIS(Ver. 2018)를 구동하여 획득한 피해 영향 범위 평가 결과와 국내·외 문헌 자료를 비교, 검토하여 제한사항과 개선 방향을 제시하였다. 또한 지하, 실내 등 특수 지점, 지역에 대한 구동 모델 구축의 필요성과 현장 대응 요원 등 포함한 주민에게 제공되는 정보의 방향성을 제안하였다. CARIS의 보완과 수정에 있어 본 연구에서 제안한 방법이 반영된다면 더욱 진보된 화학테러·사고 현장 대응 역량 체계 구축이 될 것으로 기대한다.
