• The NovaWAVE closed vessel system is a remarkably improved system over the CEM MDS 2100. Each sample has an individual magnetron and temperature monitor to more accurately control the digestion process for each sample. • RLV was used because of the large amount of existing data: almost 20 years of labdocumented element concentrations. Analysis of RLV began in 1996.

Oxygen Chemical Diffusion Coefficients of (U, Pu)O2x

Oxygen Chemical Diffusion Coefficients of (U, Pu)O2x

+

The oxygen chemical diffusion coefficient in (U, Pu)O2x was determined by thermogravimetry as functions of the Pu content, oxygentometal ratio and temperature. The surface reaction was considered in the diffusion coefficient determination. The activation energy for the chemical diffusion coefficient was 60 kJ/mol and 65 kJ/mol, respectively, in ()O2x and ()O2x.

2 concentration plays a decisive role in the denitration performance of the NTP. H 2O contributes to the oxidative removal of NO, and NH 3 improves the removal efficiency at low ED while slightly reducing the denitration performance at high ED. CO 2 has little effect on NTP denitration performance,
