Abstract
An ultimate purpose of the magnetic confinement study is creation of tokamak-reactor
as power station unit. For achievement the purposes of development of tokamak-reactors, the
necessary fundamental scientific and technological database has been obtained by efforts of
scientific laboratories, centers and institutes during many years. The first step on the way of
real utilization of fusion energy is supposed to be design and creation of ITER device. On
basis of existing and the next experimental and technological data obtained from ITER a new
DEMO project with a super-conducting electromagnetic system will be implemented.
The subject of discussion of presented work is a status of compact tokamak with
copper coils cooled by water or liquid nitrogen. Does this concept have perspectives for
design of fusion power plant? Such a possibility, on the base of sufficiently strong
assumptions, was earlier considered by GA researchers. Further, some works were devoted to
a possibility of use of compact tokamaks as CTF device or as VNS for MA transmutation. For
the VNS case, by choosing accordingly fuel composition for a blanket, it is possible to use
the energy produced in the result of MA fission by 14 MeV neutrons with the following
transformation of this energy into the electrical one, part of which will compensate own
needs and the rest part will go to energy system. Despite of hybrid character of offered
tokamak-reactor such a perspective is quite enough justified, because the risk of non-
authorized access to the plutonium is minimal because it will be in mixture with high-level
radioactive MA. Parameters and scenario of the stationary work of such a tokamak-reactor
with electro-magnetic system, cooled by water and liquid nitrogen, are based on the existing
(today's) database and are considered as quite realizable.
In given contribution a working scenario for compact tokamak-reactor with blanket
not containing fission materials is examined too. Parameters of such "pure" tokamak-reactor
are the following: R0 = 3.5 m, а = 1.75 m, ВТ = 3.9 T, IP = 19 MA, РNBI = 100 MW, ЕNBI =
500 keV, Q > 50.
Physical base for scenario of pure CT-reactor with cryoresistive coils, energy balance
for stationary regime and variant of an arrangement of such reactor are given at the presented
report.
