in the traditional solid fuel reactor, the reactor core is explicit; but in molten salt reactor, the fuel in tube connect the fuel in reactor. so how could we decide the core of this reactor? may be part of the fuel in tube will contribute the fission energy and Keff. if there are too many fission happened in tube, there are another problem we should consider, that is tube power.
attacted is a simple model which considered the contribution of tube fuel for the core. and I calculated the effect of Keff from different length of tube, it is not what I wanted.
Can any guys give me some suggestion for this problem?
thanks!

I thought the Keff will reach saturation when tube length augment. The deviation of Keff is 0.00028, so the change from 1.044 to 1.051 is not just from error but the change of tube length.
