The mass flow calculations showed that the natural uranium consumption can be reduced by more than 57% and 27% for the one-tier and two-tier cycles, respectively, when compared to the once-through fuel cycle.
The mass flow calculations show that the Transuranics (TRU) which have a long-term radiation effect can be completely burned in the recycling fuel cycles, resulting in 350, 450 and 6 times reduction of TRU inventory for the LWR ARR, LWR HTGR ARR and HTGR partial recycling fuel cycles, respectively, when compared to the once-through fuel cycle.
The details of the design of venturi meter, its different measurement and signal conditioning components, the data acquisition system and the mass flow rate calculation method are described in this paper.
The present model can be used in either design calculation (calculate the capillary tube length for given refrigerant mass flow rate) or simulation calculation (calculate the refrigerant mass flow rate for given capillary tube length).
The optimal cycle mass flow rates are calculated in a nested linear programming step where the heat integration between the cycles is optimized subject to the heat transfer feasibility imposed through Pinch Analysis cascade calculations.
This article presents an assessment of the performance of current calculation methods to predict the mass flow rate of gases below a spill edge for the range of geometries examined and proposes modifications where necessary.
Moreover, additional comparison between code and EXPRESS results are provided to ensure the accuracy of calculation program in various mass flow rates.

In addition, the number of pair ducts and total mass flow rate are taken into account during the calculation procedure.
The aspects change at the ending of calculation due to the different mass flow in PDRC and over flow sodium temperature.
