Investigation on Aerosol Pool Scrubbing Model During Severe Accidents
نویسندگان
چکیده
During a nuclear power plant severe accident, discharging gas mixture into the spent-fuel pool is an alternative containment depressurization measurement through which radioactive aerosols can be scrubbed. However, it necessary to develop code for analyzing decontamination factor of aerosol scrubbing. This article has established analysis model considering key scrubbing mechanisms and introduced Akita bubble size relationship. In addition, evaluating was established. The Advanced Containment Experiment Light Water Reactor were simulated with different sizes MELCOR default value verify suitability simulating Furthermore, simulation results compared analyzed by COCOSYS from literature, equivalent predictive ability observed. sensitivity on conducted, contribution behaviors been discussed. Finally, breakup equation revised verified conditions multi-hole bubbler in Experiment.

Nuclear Aerosol Behavior during Reactor Accidents
-Some early reactor accidents are recalled together with their associated environmental consequences. One such consequence is the generation of radioactive aerosol. We describe the various physical processes that such an aerosol cloud undergoes within the secondary containment building. These physical processes are then brought together quantitatively in a balance equation for the aerosol size ...
متن کاملScrubbing during Learning Real-time Heuristic Search
Real-time agent-centered heuristic search is a well-studied problem where an agent that can only reason locally about the world must travel to a goal location using bounded computation and memory at each step. Many algorithms have been proposed for this problem and theoretical results have also been derived for the worst-case performance. In this paper we study best-case performance and derive ...
متن کاملA Model Investigation of Aerosol-Induced Changes in Tropical Circulation
This study investigates how anthropogenic aerosols, alone or in conjunction with radiatively active gases, affect the tropical circulation with an atmosphere/mixed layer–ocean general circulation model. Aerosolinduced cooling gives rise to a substantial increase in the overall strength of the tropical circulation, a robust outcome consistent with a thermodynamical scaling argument. Owing to the...
متن کاملAn investigation on NO removal by wet scrubbing using NaClO2 seawater solution
The experiments were conducted to investigate the NO removal by wet scrubbing using NaClO2 seawater solution in a cyclic scrubbing mode. Results show that, when the concentration of NaClO2 in scrubbing solution is higher than 10 mM, a complete removal of NO can be achieved during the cyclic scrubbing process. The breakthrough time for seawater with 15 mM NaClO2 is enhanced by 34.3 % compared wi...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
