Abstract

The W 7-X deutrium plasma will produce 6.10(16) neutrons during a 10s pulse. A detailed geometrical model of the W 7-X experiment has been set up for the neutron transport calculations by the MCNP4B code. The fast neutron flux inside the torus is 100 times higher than inside the hall. The almost inhomogeneous thermal neutron flux inside the hall is reduced 30 times by doping the concrete walls with 700ppm of boron. Compared to the energy deposed by the neutrons the photon absorption is negligable for all coils.
