It has been generally accepted that nuclear power (NPP) is suiable for power supply in korea because of its economical profits and pollution-free energy. When designing or operating a NPP. The main points to be home in mind are the hazards of and protection against an uncontrolled release of the large quantities of radioactiv substances which are always generated in a nuclear reactor while it is in iperation. Multiple independent safety systems are provided which should prevent this from occurring. Thus fire prevention measures in NPP follow the “Defense-in-depth” concept. This study aims to suggest the fire prevention measures and to demonstrate information which is needed for NPP planning and its safety assessment. The findings of this study can be used as useful data for fire protection plannings at the first phase of NPP design.

Sparks cause most fire and explosion accidents in the manufacturing industry during hot work, which ignites surrounding combustible materials. Such incidents lead to high casualties due to suffocation from toxic gases and lack of evacuation. Therefore, the government recently enacted and revised 'The Occupational Safety and Health Act' to prevent fires and explosions at work sites, incorporating legal standards for fire observers, which are important in preventing accidents and the spread of fire during hot work. However, there are notable shortcomings in conducting professional cause analysis of these accidents and in aligning them with advanced foreign legal standards. Additionally, there is a lack of literature review reflecting the manufacturing industry characteristics. Despite the recent enactment and revision of legal standards, gathering sufficient opinions and professional reviews remains insufficient. To address these gaps, interviews were conducted with safety and health workers, analyzing recent fire and explosion causes in domestic manufacturing industries, and reviewing both domestic and international legal standards. Conclusively, proposed improvement measures were centered on the professionalization of fire observer education, enhancing their roles and authority realistically, and improving fire observer placement and operation standards. Consequently, additional 'Occupational Safety and Health Act' standards are necessary for fire observer education and defining the government's role. Second, precise legal standards outlining the role and authority of fire observers are required. Third tailored fire observer arrangements and management standards appropriate for varying work characteristics and company sizes are required. This study emphasizes the importance of supplementing relevant legal standards to prevent fire accidents in the manufacturing industry.

Fire protection for nuclear power plants should be designed according to the concept of "Defense in Depth" to achieve the reactor safety shutdown. This concept focuses on fire prevention, fire suppression and safe shutdown. Fire prevention is the first line of "Defense in Depth" and the licensee should establish administrative measures to minimize the potential for fire to occur. Administrative measures should include procedures to control handling and use of combustibles. Electrical cables is the major contributor of fire loads in nuclear power plants, therefore electrical cables should be fire retardant. Electrical cables installed in nuclear power plants should pass the flame test in IEEE-383 standard in accordance with NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants". To assure the fire retardant of electrical cables during design life, both aged and unaged cable specimens should be tested in accordance with IEEE-383. It can be generally thought that the flammability of electrical cables has been increased by wearing as time passed, however the results from fire retardant tests performed in U.S.A and Korea indicate the inconsistent tendency of aging and consequential decrease in flammability. In this study, it is expected that the effective methodology for validation of fire retardant performance would be identified through the review of the results from fire retardant tests.

After train fire accident in Daegue, many research on train fire safety improvement have been carrying out. Since many alternative fire safety measures can be applied in our railway system, the effect of the each safety measure must be quantified prior to the safety investment. In order to estimate the effects of each safety measure quantitatively, fault trees and event trees are constructed in this study. Results can be applied for cost-benefit analysis or sensitivity analysis for safety measures in risk assessment process.

This paper examined the problems concerning recognition of business selection and operation, etc. and the presentation of the corresponding improvement measures. For this purpose, according to the results of a questionnaire survey on recognition of detailed business operation of the fire safety shared tax, satisfaction in business execution, financial operation measures for the subject of fire fighters, fire fighters have been shown to be indifferent to the detailed business field of fire safety shared tax, investment contents, etc. in the operation of fire safety shared tax. In terms of satisfaction after execution of the shared tax, reduction of the aging rates for firefighting equipment and improvement of dissemination rate was shown to be high with Fire Sergeant (M = 3.70) and a service duration of more than 16 years (M=3.64). To improve the measures of finance, there was considerable feedback saying that the reduction in state subsidy was inappropriate. In view of the diversification and development of the fire safety shared tax businesses being operated on a limited basis along with the overlap of most state subsidy businesses with safety field businesses, legal system improvement is needed for the stable securing of insufficient firefighting financial resources so that the full amount of shared tax can be invested in firefighting fields.

Fire was and remains a great threat to historic buildings of wood. This threat is omnipresent and often results to irreparable property losses especially cultural heritages. Fire of historic buildings continues to increase every year. The purpose of this study is to preserve a life safety, historical heritage and architectural & cultural values by pursuing for fire safety in the historical buildings. This study shall employ two research methods: a literature review and field survey methods. The literature review shall focus on the observations of characteristics noted in fire codes. The field survey shall cover a heat analysis and fire protection equipment. A method is proposed to investigate fire codes related historical building, reported fire history Fire Codes and Regulations for modern buildings are not always applicable on the historic buildings. Old buildings, and some new buildings with architectural, historical or cultural importance may have values which cannot be measured on a monetary scale. Their protection against the damage caused by fire is considered to be one of the basic moral duties of society. It is strongly recommended, therefore, legislation for fire safety in historical buildings must be extended to a complementary relationship with 'active' fire protection measures, to provide safety in real historical building in real fire situations. The development and application of performance based Codes and the Fire Safety Engineering approach seems to be a rather reasonable and effective way to deal with this historical buildings.

This study aimed to identify the recognition of fire risks on their field operations among firefighters and contribute to setting up safety measures accordingly. A self-administered questionnaire were used to evaluate their recognition of job risks. About 93.4% of respondents answered they have exposed to job risks and 73.4% answered that they had high safety awareness. Our study showed that the lower service years and ranks the fire officers had, the lower relevance in statistics their awareness of the risk of the field operations and safety concerns had. The vulnerable group is those aged 20 to 39, with under 10 years of service, at a lower rank of senior fire sergeant. The study suggests coming up with the measures to motivate the officers to perform safe operations by improving their safety awareness.

In the design and maintenance of buildings, identifying the degree of damage in the event of a fire is an important factor in fire prevention and fire safety design. In order to predict fire damage, safety measures should be established by predicting the nature of evacuation according to fire, smoke and in-house characteristics, and the effects of the operation of fire safety facilities should also be considered, but in Korea, the risk analysis due to the operation of fire safety facilities is insufficient. Accordingly, this study uses fire statistics and sprinkler inspection data to analyze the degree of fire damage caused by the operation of sprinkler facilities in a probabilistic manner.
