The increase of flow rate of coolant through the grinding zone, therefore, has become extremely essential.
Helium gas is a good coolant for the fuel zone of the blanket in such a reactor in terms of neutronics performance.
This blanket is based on the use of PbLi as breeder and coolant ("self-cooled breeding zone") and high-pressure helium for cooling the structures made of EUROFER.
The proper choice of slot geometry and the arrangement of segments give improved tool performance in terms of quality of the cut, noise, abrasive wear, fatigue life of the steel centre, flow of coolant to the cutting zone, and reduced segment wear by abrasion.
The results of experimental investigations into the local hydrodynamics and inter-cell mass transfer of the coolant flow in representative zones of the KLT-40C reactor FAs behind the plate-type spacer grid are presented.
LLCB concept will be tested in ITER where Li2TiO3 ceramic breeder (CB) in the form of packed pebble beds is used as a tritium breeding material and PbLi eutectic is used as multiplier, breeder, and coolant for the CB zones.
The LLCB blanket concept consists of lithium titanate as ceramic breeder (CB) material in the form of packed pebble beds and Pb Li eutectic as multiplier, breeder, and coolant for the CB zones.
A compact coolant manifold enlarges the breeder zone.
For increasing natural circulation head, coolant velocities in each core zone are adjusted by orifice at the core inlet position.
