159. Remote coating in HTGR fuel particles

Htgr Projects in China

The high temperature gas-cooled reactor (HTGR) is a graphite moderated, helium cooled reactor with ceramiccoated fuel particles (TRISO fuel particles). The HTGR is inherently safe and expected to be applied to various industrial fields such as electric generation, hydrogen production, etc. with high efficiencies. It is also recognized as a representative advanced nuclear system for the future. ...

HTGR Unit Fuel Pebble k-infinity Results Using Chord Length Sampling

There is considerable interest in transport models that will permit the simulation of neutral particle transport through stochastic mixtures. Chord length sampling techniques that simulate particle transport through binary stochastic mixtures consisting of spheres randomly arranged in a matrix have been implemented in several Monte Carlo Codes [1-3]. Though the use of these methods is growing, ...

Acoustofluidic coating of particles and cells.

On-chip microparticle and cell coating technologies enable a myriad of applications in chemistry, engineering, and medicine. Current microfluidic coating technologies often rely on magnetic labeling and concurrent deflection of particles across laminar streams of chemicals. Herein, we introduce an acoustofluidic approach for microparticle and cell coating by implementing tilted-angle standing s...

Flame Synthesis and Coating of Nanostructured Particles in One Step

A novel process was developed for direct synthesis and in situ coating of flame-made nanostructured particles in one step. Rutile TiO2 particles made by flame spray pyrolysis (FSP) were coated in a single step with SiO2 layers in an enclosed flame reactor. This in situ particle coating was accomplished by a hollow ring delivering hexamethyldisiloxane (HMDSO) vapor (precursor to SiO2) through mu...
