The objective of the Seminar used to be to supply a global interdisciplinary discussion board for in-depth discussions at the professionals and cons of a denitration step by means of chemical potential during solidification of MAW (medium energetic waste) and HAW (highly lively waste), sooner than feeding the calciner or melter. specifically, alterations within the volatility of a few parts and aerosol formation throughout the vitrification step are of curiosity. Chemical instead of thermal denitration could have specific benefits that could simplify off-gas purification. a discount within the salt burden of waste strategies, resulting in a discount within the quantity of strong waste, can also be accomplished. The medical programme of the Seminar consisted of invited lectures simply, given by way of specialists actively engaged during this box of analysis. The emphasis used to be on broad discussions one of the individuals, with the purpose of resulting in an target realizing of the state of the art. The assembly additionally indentified matters and suggestions for destiny research.

Gompper Kernforschungszentrum Karlsruhe GmbH Institut fUr Nuk1eare Entsorgungstechnik Summary Besides formic acid and formaldehyde several organic reagents are used to decompose nitric acid. Denitration by use of sugar was first carried out at HANFORD, USA. More than 12 moles nitric acid can be decomposed per mole sucrose.
