Serpent 2 can model transient scenarios starting from a critical system.This has been achieved by the implementation of a new delayed neutron emission model based on tracking the delayed neutron precursors. New source generation routines have also been implemented. The methodology gives good results in the simple test cases tested thus far. Further validation is required. The work on the transient capabilities in Serpent 2 is still very much in progress and comprehensive testing is still required.
