A rotary reactor and a fluidized bed reactor (both laboratory-scale and operated in batch mode) are used for the treatment of granulates containing SSA and CaCl ) and treating this mixture (possible after granulation) in a rotary kiln at 1000±100°C leads to the formation of volatile heavy metal compounds which evaporate and to Pphases with a high bio-availability. Due to economical and ecologic...

The main causes of destructive steam and gas explosions with catastrophic environmental consequences during the accidents at Fukushima-Daiichi NPP were loss tightness passive safety systems reactor residual fuel removal system critical heat function in spent nuclear holding tank . lesson Fukushima accident for Ukraine's power industry is need to anticipate possibility unlikely emergency events ...

This paper considers the use of unconventional fuel in nuclear power reactors, using example a VVER-type unit, order to find out possibility saving natural fissile uranium nuclei. Saving is one important tasks, solution which will give time for development two-component industry that have no problems with resources. However, at present, reserves cheap can provide existing level global energy on...

Due to its structure, hexamethylenetetramine (HMT) is a slowly biodegradable substance, hydrolysing in acid environment to ammonium and formaldehyde. Formaldehyde is toxic under normal conditions for biological treatment processes. Following an adaptation, a formaldehyde concentration of 1000 mg·l may become biodegradable both in aerobic and anaerobic conditions. Acidic conditions for hydrolysi...

Abstract Operating conditions in the liquid metal fast reactor, like higher power density, temperature gradient, and burnup, are more severe to fuel rod comparing light water reactor. The integrity safety of is very essential reactor safety. In this study, designed for M 2 LFR-1000, which a typical pool type lead cooled evaluated using performance analysis code named KMC-Fueltra. Irradiation be...
