Title: Cross section sensitivity analysis of a proposed neutron streaming experiment with a two-dimensional model

Abstract

Cross section sensitivity analysis of a proposed streaming experiment for a typical penetration in a fusion reactor shield has been performed using a two-dimensional sensitivity method. The neutron streaming was shown to be determined mostly by the 4.5-cm-thick duct liner made of iron and the concrete structure immediately surrounding the liner. The neutrons scattered near the surface of the liner were found to be very important. A recommendation is made to move the proposed detector position to improve spatial resolution in the measurements without changing the sensitivity of the measurement to the nuclear characteristics of the duct materials.
