The presented article deals with the description of a numerical model of a corridor at a Central Interim Spent Fuel Storage Facility (hereinafter CISFSF). The model takes into account the effect of air flows on the temperature of stored waste. The computational model was implemented in the ANSYS/CFX programming environment in the form of a CFD task solution, which was compared with an approxima...

The Korean government has strived to secure a disposal site for the safe management of radioactive waste since the early 1980s. The 249 th meeting of the Atomic Energy Commission (AEC) held in September 1998 established the “National Radioactive Waste Management Policy”, which aims at completing the construction of a Low and Intermediate Level Radioactive Waste (LILW) disposal facility by 2008,...

One of the key issues that has emerged in performing a probabilistic risk assessment (PRA) for the spent fuel pool during the decommissioning phase of a nuclear power plant's lifecycle is how much credit can be given to the operating staff to respond to an incident that impacts the spent fuel pool that would, if not attended to, lead to a loss of cooling of the spent fuel and eventually to a zi...

l%e partitioning and transmutation concept (P-T) has as a mission the reductio~ by many orders of rnagnitudq of certain undesirable nuclides in the waste streams. Given that only a very small fiction of spent fiel can be “rejected” by a P-T enterp~ a P-T system must therefore be capable of accommodating a wide range of spent fuel characteristics. Variability of nuclide composition (i.e. the fee...

During the maintenance period of a future fusion reactor power plant, called DEMOnstration Power Plant (DEMO), remotely handled casks are required to confine and handle DEMO in-vessel components during their transportation between active facility. In order limit dispersion activated dust, Contamination Control Door (CCD) is designed be placed at an interface separable containments (e.g., vacuum...

The overwhelming amount of available genomic sequence variation information demands a streamlined approach to examine known pathogenic mutations of any given protein. Here we seek to outline a strategy to easily classify pathogenic missense mutations that cause protein misfolding and are thus good candidates for chaperone-based therapeutic strategies, using previously identified mutations in th...

The fuel consumption is an important component of the vehicle operating cost which is a significant component of the total transportation cost. Fuel consumption data are extensively used by transport planners, transport managers and other professional for various evaluation processes in overall gambit of sustainable transportation system. Accuracy of fuel consumption data is one of the key fact...

This paper addresses the impacts of environmental legislation and vehicle emissions on the future of alternative fuels sucl~ as methanol, compressed natural gas, propane, electricity, hydrogen, and reformulated gasoline in the transportation industry, and it discusses the advantages and disadvantages of each type of fuel in terms of fuel efficiency, fuel cost, environmental impacts, and vehicle...

in order to present a new and high performance structure of pem fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow injection into the anode and cathode reaction area field have been introduced. they consist of one inlet and two inlets and also a continuous channel. the governing equations on t...
