Contribution to the exercise on sensitivities for the NEA theoretical PWR benchmark

Sensitivity studies on a benchmark PWR shield configuration using UKNDL data have been performed and led to the identification of the cross-sections whose accuracy must influence the calculation of design parameters of interest for PWRs. Calculations for both neutrons and gamma rays were carried out using ANISN in one-dimensional cylindrical geometry in the P3S8 approximation and SWANLAKE was used for the calculation of cross-section sensitivities.
