abstract = {Spectroscopic measurements have been recently proposed in
DEMO for divertor detachment control. In its current design,
the DEMO Divertor Survey Visible High-Resolution
Spectrometer is foreseen to perform spectroscopy
measurements by integrating three optical subsystems into an
equatorial port (EP). Behind the first wall, light travels
through a set of metallic mirrors and ducts before it
reaches the closure plate of the EP. This paper presents a
nuclear analysis performed with the Monte Carlo simulation
program MCNP6 for two alternative configurations of the
system. The results show that the configuration with 5
mirrors per transmission line is very effective to reduce
the neutron streaming through the port. However, it will not
be possible, with the current design, to introduce standard
electronics along the spectroscopy ducts, as the dose rate
limits for non-critical electronic components are exceeded
in both configurations. In the plasma-facing mirrors, the
heat loads are below 2 mW/cm3, which shows that the strategy
of recessing the first mirrors and placing them behind
small-diameter openings is effective to decrease the loads
in the mirrors. FISPACT simulations for different materials
show that material transmutation in the mirrors will be
negligible throughout the DEMO reactor lifetime.},
