Sludge production is an avoidable problem arising from the treatment of wastewater. The sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. Application of aquatic worm is an approach to decrease the amount of biological waste sludge produced in wastewater ...

In reactor calculations, a detailed 3-D power density distribution is required for core optimization studies and safety analyses. The general Monte Carlo based neutral particle transport tool, MCNP [1], has the capability to obtain detailed power density distribution in a reactor through its criticality calculation mode (KCODE mode). However, there is no standard tally type in MCNP that is able...

Simulator studies are powerfull means to know, design and manage the complexity of nuclear-reactor control, if they are correctly designed for that purpose. This contribution to an international state of the art precises the trends and novelties in the use of the results, in the theories and methodologies and in the construction of the simulated situations, i.e. in the conditions for an efficie...
