Stage homogeneous

Homogenization—two-stage homogenization at medium pressures should be used. 

Reconstituted milk is most common in regions where milk production is not feasible (e. g. many Japanese cities). For production, melted butter fat is emulsified in a suspension of skim milk powder at 45 °C. The cream with a fat content of 20-30% is subjected to two-stage homogenization (20 and 5 MPa, 55-60 °C) and then diluted with the skim milk suspension.

The neutron calculations and thermal-hydraulic calculations stated in Sects. 7.5.2.1 and 7.5.2.2 are all implemented into an automatic calculation scheme written in Perl and Awk script languages. The macroscopic cross section sets and HFFs are prepared for given coolant densities and bumup states by the staged homogenization of the unit cell and the assembly transport calculation. The auxiliary mesh generation module produces the Tri-Z mesh stmcture to be used in COREBN and CITATION.
