Objectives
Improvements of the nuclear model simulations based on the TALYS code.
Calculations of the covariances up to 200 MeV using Unified Monte Carlo approach.
Inclusion in the files the new data for resonance region.
Preparation of the neutron transport data files for Cr-50,53,54 isotopes for incident energies up to 200 MeV.
Benchmarking of the newly developed neutron data files.
Compilation of the integral experimental data on Cr.MCNP benchmark transport calculations.Correction of the evaluated data if necessary.
23-26 March 2010, IAEA, Vienna3
Nucelar model calculations
TALYS-1.0 code was used for the nuclear modles calculations up to 200 MeV incident neutron energies
GDH model for the preequlibrium reactions was included in the code
The detailes are reported by A. Konobeyev (EFFDOC-1102)GDH model is included in TALYS as an option (preeqmode 5)TALYS executable and source files are available
Global OMPs for deuterons, tritons, helions and alphas are used instead of folding approach
Generalised superfluid model for level densities
The set of the best model parameters was found on the basis of the optimization procedure (Monte Carlo simulations)
23-26 March 2010, IAEA, Vienna4
Quality assurance of the evaluated data
TALYS code for the nuclear model calculations
Well proved nuclear models
Inclusion of the new resonance data
Detailed comparison with available experimental data
