The occurrence of a corona is that electrical discharge due to the heterogeneity that occurs when an electrical field is concentrated in an electrode due to a cusp formed on said electrode. Wire treatment at the end of a 154[kV] dead end clamp for end users accelerates the occurrence of corona, which in turn leads to power loss and noise. In this study, the characteristics of the corona which occurs between porcelain insulators and support clamps of overhead lines used in 154[kV] power receiving facilities for end users were investigated. The corona, which cannot be identified by one common method, was measured utilizing a UV image camera. A risk assessment for fire damage and its status was suggested. The stress distribution of the electrical field by length of bare wire was suggested by means of the finite element method(FEMLAB). As a result, it was found to affect a porcelain insulators. These results can be utilized for the enhancement of clamp installation and safety in power facilities.

As the demand for hydrogen increases, the facilities for storing hydrogen has been important, and a few laws for hydrogen facilities should be complied. According to the Occupational Safety and Health Act in Korea, in case liquid hydrogen with a storage capacity of 5 tons or more is handled, a Process Safety Management (PSM) system should be complied. However, there are some standards which are not proper for flammable low-temperature liquefied substances on the current Occupational Safety and Health Act. In this study, 7 key points in process safey information and safety operation procedures among PSM components are suggested and how these key points should be improved is derived based on scientific analysis.

When NaOCl was generated and put into sea-water cooling machine in order to overcome the biological hindrances against sea-water cooling machine, it was converted into metallic ion, particularly Ca and Mg, as a hydrate in sea-water and is to stick to electrolyte as a side reaction. This phenomena make the distance between the electrolytes narrow to decrease the flow rate, which induces the local vortex flow which erodes the pole plate. Moreover, this increases the resistance of the electrolyte as well as voltage to decrease the electrolytic efficiency, which has curtailed a chlorine yield and caused a pole plate cut. We are able to overcome these problems by chemical cleaning and intend to extend the life-time of electrolyte and to increase output of the sea-water electrolysis facilities by studying optimal policy regarding chemical cleaning of electrolytic cell. Cleaning time of electrolytic facilities is determined when both increase in electrolytic efficiency and decrease in pole-plate voltage are 10%. At this time as operating current of electrolytic facilities is high, operating time is diminished. Whereas, parameter of end point determination according to cleaning is Mg ionic concentration in solution. When we use Cleaner as a 7wt% HCl, cleaning time is about 80min proper. We are able to maintain pole plate performance by protecting against pole plate cut by means of electrolytic by-product, improve operating rate of facilities, and cut down on maintenance expenditure after acidic cleaning.

This article analyzed the building regulations, the guidelines for the people with disabilities, and the interior environment of the transportation facilities of Stockholm and Oslo, which wee capital cities of leading countries in this field. Result showed that Swedish 'BBR 94' was made and based on accessibility, safety, and efficiency. But the mandatory items and detailed recommendations were minimal. 'The Swedish Handicap Institute' provided more detailed requirements. As a result of case studies of 4 facilities, it appeared that these facilities used sufficient dimension, variable color, different material, or adaptable lightings in order to provide easy accessibility, adaptability, safety, support, and mobility for the people with disabilities instead of keeping the building regulations and guidelines reluctantly.

As interest in sustainable and eco-friendly energy increases due to various problems in the carbon economy, a hydrogen economy that utilizes hydrogen as a main energy source is emerging. Among the methods of producing hydrogen, the water electrolysis method based on renewable energy produces environmentally friendly green hydrogen because it produces hydrogen from water. The water electrolysis facility currently under development produces hydrogen by receiving electricity directly from renewable energy and uses KOH(potassium hydroxide) as an electrolyte. In this study, HAZOP(Hazard and Operability Study), a qualitative risk assessment, was conducted on alkaline water electrolysis facilities to find problems and risk factors in the design and operation of water electrolysis facilities. Risks related to oxygen and KOH, an electrolyte, were identified as major risks, and it is believed that the safety of facilities and workers can be secured based on emergency action plans and safe operation procedures.
