Abstract

New evaluations for the tungsten isotopes ^{180,182,183,184,186}W in the neutron energy range up to 150 MeV were produced, including the covariance information. Minor adjustments to the existing resonance parameters were made. Evaluations in the fast energy region were based on nuclear model calculations using the EMPIRE-2.19 code; covariance data were generated with the Monte Carlo technique to produce a prior estimate for the covariance matrix. Experimental data were introduced through the GANDR system. The evaluated files were tested on selected fusion neutronics benchmarks and fast reactor benchmarks. Marked improvement in predicting measured integral parameters was observed, compared to the ENDF/B-VII library.
