The paper discusses some technical solutions allowing to implement a collisionless mode
with surface ionization in high-temperature thermionic nuclear power units and to for-
malize their future look. On the base of analysis we selected structural materials capable
of providing performance and required output parameters at increased temperatures of
electrodes. In particular, to provide the isothermal condition for the energy converter we
consider a structural configuration with the energy converter placed beyond the reactor
core. As a result, we obtain a perspective single-channel multi-element configuration of
the electro-generating unit, which considers disadvantages of both single-element con-
figuration and classic multi-element configuration. Besides, structural configuration of
thermionic electro-generating assembly with the external nuclear fuel placement, which
provides the simplicity of the design and the principle of modularity, is proposed. For
further development of the suggested design a tentative estimation using CFD-software
Star-CCM+ was carried out. It represents a static thermal numerical computation of
channel’s part with a length of 10 mm. Computation results are presented in the paper.
Keywords:
nuclear power unit, high-temperature thermionic unit, thermionic converter,
external placement, heat pipe, configuration, static thermal computation, future look.
