 ''Figure 1.: BME Training Reactor image of the core, model geometry and  simulated neutron density'' 
 
-The right-hand-side image of the neutron population is a snapshot of particles after exactly 10^-6^ seconds. Most of the neutrons are in the water due to their lower speeds. Note that the geometry image is not superimposed here, the material changes are only visible in accordance with the neutron population change.

Fig. 2 shows the distribution of  fission positions happening in the firs 10-3^ seconds.

+== Time evolution in a subcritical assembly
+
+
+The subcritical model was a 30 cm radius water sphere with 61 UO,,2,, cylindrical fuel rods of 40 cm length, 1 cm radius spaced 1 cm apart from each other see Fig. 3.. Uranium was 4.7% enriched and fuel rod density was taken as 10.5g/cm^3^.

+
+At time zero a point source emitted neutrons in the middle of the geometry. Afterwards the time evolution of the neutrons were followed. Results in terms of fission distribution along the cross secion of the geometry are shown in Fig.4
