The fuel zone, containing MAs as spheres cladded with W-5Re, has been located behind the first wall to utilize the high neutron flux for transmutation effectively.
Helium gas is a good coolant for the fuel zone of the blanket in such a reactor in terms of neutronics performance.
Thermal-hydraulic analysis indicates that the temperatures of the fuel zone are well below the limited values and a large safety margin is provided.
The first class of particles has been found in the fuel zone and across the stagnation plane of the opposed-flow flame.
This paper proposed a scheme of for a helium-cooled high power density blanket for a fusion fission hybrid reactor with about 100 MW/m3 average power density in the fuel zone.
These include increasing the height of reactor core, optimizing the thickness of fuel zone and better selection of the scheme of central graphite zone, etc. Basic design concepts and thermal hydraulic parameters of the HTR PM are given.

In the lattice calculations, a boron burnable particle is modeled as a small sphere located at the center of a concentric spherical cell, surrounded by the effective fuel particle zone and fuel-free graphite zone with the same volumetric ratios as in the real fuel pebble.
The temperature increase promotes aromatics production in the fuel pyrolysis zone and changes the relative contributions of the thermal and Fenimore mechanisms into NO formation.
We proposed a dynamic calibration method for tracking the projection of the fuel-free zone accurately, instead of using a fuel-free zone mask of fixed size and position.
After the projection data in the fuel-free zone were extracted, image and graphic processing methods were combined for automatic recognition of escaped coated fuel particles, and some practical inspection results were presented.
Several fuel loading zones may be used since radial mixing of the pebbles was shown to be limited.
