The image below shows the coupling between a typical ECCO core ceramic and an ultrasonic horn that would fluidise the carefully sized fuel components at their resonant 1Mhz.
This transducer attachment is for a fuel tube with an inner diameter of 8.1 mm and an outer diameter of 11 mm.
This is a larger core than that discussed in previous ECCO technical discussions and forms part of a reactor under going trials now that is designed to take a larger quantity of fuel.
Update based on 5th Technical discussion
- Alumina cement is used to create a heat resistant couple between the ultrasonic horn and the reactor. Aluminium was used initially but this melted and was lost.
