... Abstract In this study, we propose a hierarchical framework using task ontology, which is used in information science and information engineering, to organize decommissioning information. As background, decommissioning of nuclear facilities generally takes a long time, so it is important...

... and a rethinking of existing routines and processes. First, this paper identifies the technological and organizational requirements for a K-PIM. Two particular anchor points here are tacit knowledge in the context of knowledge management as well as the decommissioning phase. The effects of knowledge gaps...

... Abstract Basically, decommissioning of nuclear facilities is a project that does not generate new profit because it is carried out with the reserve funds from operation, etc. Therefore, its cost should be minimized with optimization by shortening the process and minimizing the waste, etc...

... Abstract Decommissioning for nuclear power plant is complex project, which is needed to be taken into account during the early phase of design stage. Many researches and practices have already done for nuclear decommissioning activities. The decommissioning chapter is defined in preliminary...

... Abstract The decommissioning technology of nuclear facilities has been one of the most important research directions of nuclear industry for several decades, and further enhancements are being carried out in the world. The global published patents about the decommissioning technology of nuclear...

... in the reactor pressure vessel (RPV) and primary containment vessel (PCV). The Japanese Government has drawn a mid- and long-term roadmap towards 1F decommissioning. However, three reactors’ decommissioning work has faced difficulties due to the lack of realistic information about the damaged cores...

... rod blades are comprised of a stainless steel sheath, which contains neutron absorber tubes (filled with boron carbide powder). During decommissioning, the first stage of size reduction consists of cutting the connector (bottom portion) of the control rod, while the second stage consists of separating...

... Abstract In decommissioning sodium-cooled fast reactors, the operators can be exposed to radiation during dismantling of cold trap equipment (C/T). The C/T is higher dose equipment because the C/T trapped tritium of fission products during the operation to purify the sodium coolant...

... of International Research Institute for Nuclear Decommissioning (IRID), has developed several devices and has investigated inside of PCV. The investigation devices for unit 2 are roughly categorized into three types. For the investigations in early stages, just a camera and sensors with simple support tools were...

... Research Institute (Georges et al. 2017). The objective is to obtain quantified data for evaluating the risk of disseminating contamination when implementing cutting tools such as laser or others such as mechanical one, over the next few years, in the process of decommissioning the damaged reactors...

... Abstract Decommissioning of the Fukushima Daiichi nuclear power station is challenging due to industrial and chemical hazards as well as radiological ones. The decommissioning workers in these sites are indicated to wear Personal Protective Equipment (PPE) appropriately for radiation protection...

... already. The Jinan MNSR decommissioning documents were approved by Chinese competent authorities in Dec. 2010. The work on site was started in Jan. 2011, and completed in March 2011, the wastes were removed from the Jinan MNSR site. The decommissioning scope of JiNan MNSR includes decommissioning of its...
