GuarDyan_PhysModel
v6 v7 21 21 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. 1.. Uranium was 4.7% enriched and fuel rod density was taken as 10.5g/cm^3^. 22 22 23 [[Image(UOH2O_geometry.png, 400px, title=Geometry of the subcritical verification model)]] \\ ''Figure 1. :Geometry of the subcritical verification model''23 [[Image(UOH2O_geometry.png, 400px, title=Geometry of the subcritical verification model)]] \\ ''Figure 1.: Geometry of the subcritical verification model'' 24 24 25 25 Similarly, a time-energy spectrum is registered in this case as well. … … 28 28 29 29 For each isotope a figure has been created for visual inspection see Fig. 2. Separate figures are energy spectra of the number of particles crossing the sphere outer surface divided by the starting particle number, each figure belongs to a separate time interval. 30 31 [[Image(B-011_1e-6MeV.png, 400px, title=Example of Time-Energy Spectra comparison graphs)]] \\ ''Figure 2.: Example of Time-Energy Spectra comparison graphs for ^11^Be, 10^-6^ MeV'' 32 33 34 As a result a total of some 445 000 data points were compared at the final stage. 35 36 $\chi ^{2}=\frac{1}{N}\sum_{i=1}^{N}\frac{(y_{MCNP,i}-y_{GUARDYAN,i})^{2}}{\sigma_{MCNP,i}^{2}-\sigma_{GUARDYAN,i}^{2}}$ 37 30 38 31 39
