Target Accuracy Definition (ANL) T. Taiwo (G. Palmiotti)
The Process • Combining many existing documented sources and expert judgment from people involved in the design of SMFR and ABTR • Main Sources: • Khalil’s Gen IV list with feedbacks from Gen IV workshop • McKnights’ List: a compilation of different sources (Brookhaven meeting on Gen IV data needs) • Kusters and Pilate, Progress in Nuclear Energy, Vol. 16, pp. 201-229, 1985 • Proceedings of NEACRP Specialists’s Meeting, NEACRP-L-307, Jackson Hole, Wyoming, September, 1988 • Expert judgment of: R. Hill, R. McKnights, W. Yang, and G. Palmiotti
Summary • Target accuracy have been defined for major neutronic parameters that impact design and safety requirements. • Distinction has to be made between the conceptual phase (viability) and final design phase (performance). • Maybe there is a need to differentiate target accuracies for different systems (e. g. advanced ones from more established ones) • In some cases the target accuracy for the performance assessment could be very stringent (e. g. peak power). • One has to be careful in order to separate uncertainties coming from methods (bias for deterministic ones and stochastic variation for Monte Carlo) from those coming from cross sections.
