A one-pass simplified analysis method for steady state PWR
core has been developed. The advantages over the other multistage
approaches have been discussed and compared- Recommended nodal
patterns for modelling the reactor core have been proposed. Also
the effect due to the lumped channel technique utilized in both
the simplified method and existing multistage methods has been investigated for both D and 3D problems. For the nodal pattern recommended
with the proposed one-pass analysis method, use of the lumped channel
technique introduces negligible errors.New England Electric System, Northeast Utilities Service Co. under the MIT Energy Laboratory Electric Power Progra
