The responsible use of calculational methods in nuclear criticality safety includes a
determination of bias and bias uncertainty that may exist between the calculated results and reality.
Such biases exist due to approximations used to model the real world, uncertainties in nuclear data,
and approximations associated with the calculational method (e.g., Monte Carlo method). The bias
and bias uncertainty are typically determined by using the modeling approximations, nuclear data, and
calculational method to model well-known, usually critical, systems.
