320 Fundamentals of Magnetic Thermonuclear Reactor Design

Development and experimental verification of computational codes:
l Neutron science computations needed to determine the TBR, radiation
energy release, shielding properties and drop in residual energy release/
radioactivity.
l Thermal physics and hydraulics computations with respect to intense heat
fluxes and volume energy release, with due account for convective and
radiative forms of heat transfer.
l MHD calculations for an electrically conductive liquid moving in complex-
geometry ducts through a 3D magnetic field.
l Electromagnetic computations for an abruptly changing magnetic field.
l Mechanical strength analysis in a complex-geometry structure with account
for the meaningful time evolution of materials’ properties.
Development and pilot production of new measuring and diagnostic instru-
ments able to retain their function in fusion reactor severe environment. The
values to be controlled are the following:

−2
19
l neutron flux density (up to ∼10 cm ),
l tritium breeding rate,
l magnetic field strength (up to ∼16 T),
l temperature (20–1000)°C,
l gas, water and liquid metal pressures,
l coolant flow rate,
l tritium flows,
l coolant impurity content,
l mechanical stresses, deformations and dislocations in the structure,
l electromagnetic forces.
