The damages on buildings and urban facilities caused by disaster from climatic change is unpredictable. Moreover, the scale and power of disaster are totally different from what we have undergone. so it's almost hard to cope with. According to climate changing, the grade of natural disaster getting worth. It is really dangerous fact in point that natural disaster like flood causes to cut off the urban energy supply, municipal lifeline, and bring the emergency to city. As the sudden urbanization and centralization, damage is serious. It's an important theme to secure its function in the urban environmental engineering field about buildings which are thought it's important just like business, a hospital and a government office in case of emergency. It's possible to utilize a concept of a safe household and apply it by a casting plan of emergency energy demand and supply in an urban area for high urban function town‘s preparation in the time of disaster. In this paper, when natural disaster in an urban area with climatic change, for proposing to introduce a concept of safe house and safe housing as a building including a concept of special dwelling of the restored dimension. we search not also maintenance of function in a building but the order of priority-like plot of emergency energy demand and supply between the building in the city and we'll prepare basic material in a safe area and a safe house as management system of the city unit about emergency energy securement and system of supply and demand.

As we can see in the case of the Fukushima nuclear power plant accident, the integrity of containment is directly related to the safety of a nuclear power plant. Because of this, various concepts, such as the Passive Containment Cooling System(PCCS), are in the process of research to ensure the integrity of the containment. In this study, the PCCS was designed in the form of a assembly where several Two-Phase Closed Thermosyphons(TPCT) comes together to form one adiabatic region by grafting TPCT, to minimize the number of penetrations on the top of the dome of the containment as well as to remove the decay heat. The main purpose of this study is to analyze the expected heat transfer phenomena and to confirm the interpretation of the resulting heat transfer coefficient when applying the TPCT assembly of Multi-Pod Heat Pipe(MPHP) to the APR1400.

The damage and urban architecture, there is also a direct damage, such as destruction of the city and built in disasters and disaster occurs, but the functionality road, gas, electricity, water and sewerage, communications, and other main lifeline is (life line) there is also indirect damage that paralyze. It is necessary to consider a judicial and technical standards for the functional maintenance of disaster. In particular, government facilities, and complete the anti-communist issue most, it is operated as a shelter and exhibition of actual disaster. It has been recognized as a concept of maintenance facilities of important urban functions to disaster. Disaster prevention activities in the event of a disaster, that is, it has appeared as a basic element which is indispensable to such restoration to understand and predict disaster, contrast, the damage situation. When you lose the function of the government office, the economic loss lifesaving, emergency restoration, safety confirmation, etc. In this study, refers to the emergency cut off and power shortages due to the disaster and disaster, and renewable energy for functional maintenance of important equipment for functional maintenance of equipment due to the delay of the recovery time of emergency government buildings it is intended to study measures to take advantage of, and to ensure the reliability of the emergency power supply.

Multi-Pod Heat Pipe(MPHP) is a new concept of assembly type of Two-Phase Closed Thermosyphon(TPCT) that was designed to be applied to the Passive Containment Cooling System(PCCS) of the nuclear power plant, using the characteristic of TPCT’s heat transfer according to the phase change of the working fluid. Main purpose of this study is to verify the function of the MPHP designed to remove decay heat that occurs in the containment, in the event of severe accidents, by crafting miniatures and through it, to verify the maximum heat value that the assembly type TPCT is able to cool down. The experiment was conducted in the ranges of 6~9kW, based on the theoretical results, and as a result, the maximum internal temperature increased by 2℃with each increase of 1kW, and the temperature of the steady state was maintained at the 112℃~114℃. Due to the fact that the heat transfer was more actively than expected, the internal pressure of the Boiling tank decreased before reaching the accident conditions, it was confirmed that more than 100% of the heat transfer took place rather than theoretically calculated expectation of 7kW of heat removal.
