Abstract EN
In order to analyze the steady state and transient behavior of CNA-II, several tasks were required.
Methods and models were developed in several areas.
HELIOS lattice models were developed and benchmarked against WIMS/MCNP5 results generated by NA-SA.
Cross-sections for the coupled RELAP5/PARCS calculation were extracted from HELIOS within the GenPMAXS framework.
The validation of both HELIOS and PARCS was performed primarily by comparisons to WIMS/PUMA and MCNP for idealized models.
Special methods were developed to model the control rods and boron injection systems of CNA-II.
The insertion of the rods is oblique, and a special routine was added to PARCS to treat this effect.
CFD results combined with specialized mapping routines were used to model the boron injection system.
In all cases there was good agreement in the results which provided confidence in the neutronics methods and modeling.
A coupled code benchmark between U of M and U of Pisa is ongoing and results are still preliminary.
Under a LOCA transient, the best estimate behavior of the core appears to be acceptable.
