Real time boiling water reactor core simulation

The authors discuss the Westinghouse real time boiling water reactor core model has been derived from the BWR nuclear design code POLCA. In particular, the cross section treatment is identical to that currently used in POLCA. Using design code methodology assures that reactor core response is accurately predicted over the entire range of conditions from cold shutdown to hot full power without reliance on empirical adjustments. This first principles approach to simulation allows the model to directly calculate difficult phenomena such as the reverse power effect
