“…High energy neutrons from fusion reactions have the capability to transmute long-lived radioactive isotopes into shorter-lived or non-radioactive isotopes, reducing the volume and hazard of high-level nuclear waste. The reader can find conceptual design for nuclear waste treatment in (Parish and Davidson, 1980;Stacey et al, 2002;Şahin and Übeyli, 2004;Mehlhorn et al, 2008).…”

Nuclear fusion technologies have re-gained momentum in the last decade thanks to their disruptive potential in different fields, such as energy production and space propulsion, and to new technological developments, especially high temperature superconductor tapes, which allow overcoming previous performance or design limits. To date, reviews of recent nuclear fusion designs are lacking. Therefore, this paper aims at giving a comprehensive overview of nuclear fusion concepts for industrial applications with a focus on the private sector. The designs are classified according to the three leading concepts for plasma confinement, namely, magnetic confinement, inertial confinement and magneto-inertial confinement. The working principles of the main devices are described in detail to highlight strengths and weaknesses of the different designs. The importance of the public sector on private projects is discussed. The technological maturity is estimated, and the main criticalities for each project are identified. Finally, the geographical distribution of the companies (or public institutions) pursuing the design of fusion devices for commercial applications is reported.

“…Fusion-fission hybrid systems have the potential attractiveness of providing rich neutrons for applications of nuclear waste transmutation and fissile fuel breeding while easing the requirement of fusion plasma technology (with a low fusion gain Q) and plasmafacing material technology (with a low neutron wall loading), which represent a possible use of fusion power to build a power reactor with the current understanding of plasma physics and technologies. A lot of research activity has been done to evaluate the possibility of the hybrid systems in China and other countries in the world [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]; however, most of these were based on advanced fusion and fission technologies.…”

A fusion-driven hybrid subcritical system (FDS) concept has been designed and proposed as spent fuel burner based on viable technologies. The plasma fusion driver can be designed based on relatively easily achieved plasma parameters extrapolated from the successful operation of existing fusion experimental devices such as the EAST tokamak in China and other tokamaks in the world, and the subcritical fission blanket can be designed based on the well-developed technologies of fission power plants. The simulation calculations and performance analyses of plasma physics, neutronics, thermal-hydraulics, thermomechanics and safety have shown that the proposed concept can meet the requirements of tritium self-sufficiency and sufficient energy gain as well as effective burning of nuclear waste from fission power plants and efficient breeding of nuclear fuel to feed fission power plants.

In this study, neutronic investigation of a deuterium-tritium (DT) driven hybrid reactor using ceramic uranium fuels, namely UC, UO 2 or UN under a high neutron wall load (NWL) of 10 MW/m 2 at the first wall is conducted over a period of 24 months for fissile fuel breeding for light water reactors (LWRs). New substances, namely, Flinabe or Li 20 Sn 80 are used as coolants in the fuel zone to facilitate heat transfer out of the blanket. Natural lithium is also utilized for comparison to these two innovative coolants. Neutron transport calculations are performed on a simple experimental hybrid blanket with cylindrical geometry with the help of the SCALE 4•3 System by solving the Boltzmann transport equation with the XSDRNPM code in 238 neutron groups and an S 8-P 3 approximation. The investigated blanket using Flinabe or Li 20 Sn 80 shows better fissile fuel breeding and fuel enrichment characteristics compared to that with natural lithium which shows that these two innovative coolants can be used in hybrid reactors for higher fissile fuel breeding performance. Furthermore, using a high NWL of 10 MW/m 2 at the first wall of the investigated blanket can decrease the time for fuel rods to reach the level for charging in LWRs.
