  • The Korean nuclear industry is developing a thermal-hydraulic analysis code for safety analysis of pressurized water reactors (PWRs). The new code is called the Safety and Performance Analysis Code for Nuclear Power Plants (SPACE). The SPACE code adopts advanced physical modeling of two-phase flows, mainly two-fluid three-field models which comprise gas, continuous liquid, and droplet fields and has the capability to simulate 3D effects by the use of structured and/or nonstructured meshes. The programming language for the SPACE code is C++ for object-oriented code architecture. The SPACE code will replace outdated vendor supplied codes and will be used for the safety analysis of operating PWRs and the design of advanced reactors. This paper describes the overall features of the SPACE code and shows the code assessment results for several conceptual and separate effect test problems.

  • "International Safety Management(ISM) Code" means the International Management Code for the Safe Operation of Ships and for Pollution Prevention as adopted by the Assembly, as may be amended by the International Maritime Organization. This Code have brought into force internationally since 1th July, 1998 by incorporated to the new Chapter Ⅸ in the SOLAS Convention. Accordingly those States which give effect to the SOLAS Convention will have to ensure that rules giving effect to the Code are introduced into their domestic legislation. The purpose of this Code is to provide an international standard for the safe management and operation of ships and for pollution prevention, by this to reduce the maritime casualty which could caused by neglect of person. To achieve this purpose the ISM Code specifies a number of broad 'safety management objectives' for owning or operation companies, and it requires that such companies should establish, implementing and maintain a written Safety Management System(SMS) covering a whole range of safety environmental and related matters. These requirements of the Code could effect on the carrier in some points such as duty of due diligence to care for cargo, due diligence to make the vessel seaworthy and burden of proof etc. In this respect, We should know that the ISM Code could effect on the carrier advantageously or disadvantageously subject to whether the carrier observed the requirement of the ISM Code. Although it does not add cause of liability or increase limitation of liability imposed to the carrier.

  • Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

  • The Korean nuclear industry had developed the SPACE (Safety and Performance Analysis Code for nuclear power plants) code, which adopts a two-fluid, three-field model that is comprised of gas, continuous liquid and droplet fields and has the capability to simulate three-dimensional models. According to the revised law by the Nuclear Safety and Security Commission (NSSC) in Korea, the multiple failure accidents that must be considered for the accident management plan of a 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 is required for the separate and integral effect experiments. Therefore, the goal of this work is to verify the calculation capability of the SPACE code for multiple failure accidents. For this purpose, an experiment was conducted to simulate a Control Element Drive Mechanism (CEDM) break with a safety injection failure using the ATLAS test facility, which is operated by Korea Atomic Energy Research Institute (KAERI). This experiment focused on the comparison between the experiment results and code calculation results to verify the performance of the SPACE code. The results of the overall system transient response using the SPACE code showed similar trends with the experimental results for parameters such as the system pressure, mass flow rate, and collapsed water level in component. In conclusion, it can be concluded that the SPACE code has sufficient capability to simulate a CEDM break with a safety injection failure accident.

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.

  • The purpose of this study is to suggest new safety code to improve the safety of the flare safety system. Firstly, we analyzed the major accidents occurred at the flare system since 1996 and proposed 3 articles which is required to be added newly to the existing KOSHA code. Secondly, we also performed the HAZOP study for each study node and also suggested 5 articles. Finally, we analyzed the commented contents of PSM reports which have been submitted from the enterprise located in Honam province since 2005 and proposed 5 articles as well. We understand that all 13 articles proposed above, should be added to the KOSHA code in order to improve the safety in the flare system and to prevent the major fire and explosion accidents in the design stage.

  • Current food-traceability platforms suffer from problems such as inconsistent traceability standards, a lack of public credibility, and slow access to data. In this work, a combined code and identification method was designed that can achieve more secure product traceability using the dual anti-counterfeiting technology of a QR code and a hidden code. When the QR code is blurry, the hidden code can still be used to effectively identify food information. Based on this combined code, a food-safety traceability platform was developed. The platform follows unified encoding standards and provides standardized interfaces. Based on this innovation, the platform not only can serve individual food-traceability systems development, but also connect existing traceability systems. These will help to solve the problems such as non-standard traceability content, inconsistent processes, and incompatible system software. The experimental results show that the combined code has higher accuracy. The food-safety traceability platform based on the combined code improves the safety of the traceability process and the integrity of the traceability information. The innovation of this paper is invoking the combined code united the QR code's rapidity and the hidden code's reliability, developing a platform that uses a unified coding standard and provides a standardized interface to resolve the differences between multi-food-traceability systems. Among similar systems, it is the only one that has been connected to the national QR code identification platform. The project has made profits and has significant economic and social benefits.
