Effective delayed neutron fraction and prompt neutron lifetime of Tehran research reactor mixed-core.

open access: yesAnn Nucl Energy, 2013
In this work, kinetic parameters of Tehran research reactor (TRR) mixed cores have been calculated. The mixed core configurations are made by replacement of the low enriched uranium control fuel elements with highly enriched uranium control fuel elements in the reference core.
