Modern Nuclear Data Evaluation with the TALYS Code System

摘要: Abstract This paper presents a general overview of nuclear data evaluation and its applications as developed at NRG, Petten. Based on concepts such robustness, reproducibility automation, modern calculation tools are exploited to produce original libraries that meet the current demands quality completeness. requires system which comprises differential measurements, theory development, model codes, resonance analysis, evaluation, ENDF formatting, processing integral validation in one integrated approach. Software, built around TALYS code, will be presented all these essential components seamlessly integrated. Besides basic extensive format testing, second goal lies diversity for different type users. The implications this scheme unprecedented. most important are: 1. Complete ENDF-6 files, form TENDL library, including covariance matrices, many isotopes, particles, energies, reaction channels derived quantities. All isotopic files mutually consistent supposed rival those major world libraries. 2. More exact uncertainty propagation from physics applied (reactor) calculations based Monte Carlo approach: “Total” (TMC), using random 3. Automatic optimization systematic feedback measurements back data. method work also opens new way approaching analysis applications, with consequences both safety installations, several examples given here. experience is final step improve data, change users vision finally orchestrate their integration into simulation codes.
