Motivations

Physor 2012D. Rochman – 2 / 16

We need aconsistent and completenuclear data library to be integrated in reactorcalculations, including realistic covariance data.

(None of the existing libraries fulfill these requirements.)

� Use global, robust TALYS method for the bulk of nuclides� Use in-depth evaluation, adjustment... for important nuclides (e.g.56Fe,239Pu)� Reproducible library

Produce TENDL-2008, -2009, -2010... with an increasing quality with regard to:differential data, model development, integral validation, completeness and covariancedata

Standard and modern approaches

Conclusions and Future improvements

Physor 2012D. Rochman – 16 / 16

☞ Consistent, complete data files with automatic updates for all nuclides, projectiles,energies reaction channels and quantities,

☞ Includes 315 URRs, random files☞ Detailed TALYS and resonance parameter fitting per individual isotope

Release date: December 28th, 2011

☛ Possibility to adopt an entire existing data library (e.g. JEFF-3.1.1) andmake itcomplete

☛ More extensive validation (burn-up...) with uncertainties☛ Improve global model and uncertainties, Addition of original URR
