Since the accident of Fukushima Nuclear Power plant in 2011, people have been more interested in radiation safety in life. This study investigated the level of exact recognition of 6 warning pictograms enacted and utilized as per Korea Industrial Regulation in relation to medical & natural radiation safety at this time. Unless people recognize pictogram prepared for radiation safety correctly in accordance with its purpose, safety would be severely intimidated. The result of corroboratively analyzing recognition of radiation safety pictogram is as follows. First, some 63.3% of respondents negatively responded on understanding 6 pictograms related to radiation in life, showing low level of understanding. Second, the average mark of correct response on the questions asking the meaning of 6 pictograms presented in relation to radiation safety in life was 2.79 point (standard deviation 1.447 point), which was relatively low. As seen above, the level of recognition & comprehension is low, because education related to life radiation safety in the school is insufficient and the present warning pictogram established by Korea Industrial Regulation needs to be revised & supplemented. This study is meaningful in that the method of using pictogram is presented as one of diverse efforts to improve life radiation safety.

This year marks the 35-th anniversary of the events related to the liquidation of the consequences of the accident at the Chernobyl nuclear power plant (Chernobyl NPP) and their most important stage - the closure of the destroyed 4-th power unit with a special structure, which was initially called the «Sarcophagus» (later the «Shelter» object). This article presents information about the period May-November 1986 in the aspect of radiation safety of the builders of this unique facility.

A commonly used treatment for laundry waste and floor drain water in a nuclear power plant (NPP) in China involves filtration, followed by passing through a mixed ion exchange bed or evaporator. Due to the presence of foam and suspended solid in the laundry waste, the treatment systems require frequent maintenance and have a short filter service life. Pall ARIA™ platform, a hollow-fiber membrane based Micro-Filtration (MF) technology, was recently used at a German nuclear power plant to upgrade the low level radioactive laundry waste treatment system. The MF system with 0.1 μm average pore size and totally automated backwashable design was able to successfully concentrate the low level radioactive waste before it was sent to the evaporator. An 18-month long pilot test of the MF system, with a flow capacity of 3–6 m3/hr, using 3 modules, was performed at the 1300 MW, Pressurized Water Reactor (PWR) nuclear power plant, at Phillipsburg, Germany, to substitute its legacy centrifuge separators in waste water treatment system. During the long pilot testing, the MF technology amply demonstrated its capability for consistent high particulate removal efficiency, safe & reliable operation and high availability with average recovery rate of 95%. An average activity of 17900 Bq/m3 was reported in the filtrate. The 20X concentrated stream from the MF system was processed by the evaporator. The paper discusses the current liquid radwaste treatment practices in China, and the details of 18-month long trial of the MF system at Phillipsburg NPP.

Main principles and criteria for nuclear and radiation safety of a floating nuclear power plant have been considered. It has been shown that the existing regulatory framework, technical and organizational safety measures for nuclear and radiation safety of a floating nuclear power plant are sufficient, and operation of the floating nuclear power plant won't lead to an irradiation of the population above recommended norms both at its normal work, and in case of project accidents and under-project ones.
