SOFT 2018 Contribution ID: 1272 Type: not specified P3.225 RFP based Fusion-Fission Hybrid reactor model for nuclear applications. Wednesday, 19 September 2018 11:00 (2 hours) A hybrid fusion-fission (HFF) reactor based on a Reversed Field Pinch (RFP) configuration looksasanat- tractive option from both a technical (simple design, easy machine assembly and maintenance) as well as economic perspective (low investment costs due the absence of large Heating and Current Drive systems and superconductive toroidal field coils). The hybrid reactor studied here has a RFP fusion core generating 40MWth fusion power via D-T reactions. The reactor size (R=6 m, a =1), its components design and plasma performances have been extrapolated from the results of RFX-mod, the largest RFP experiment built so far. With a plasma temperature of 9.6 keV and an ohmically driven plasma current of 20 MA, the fusion reactions produce 2.2E+19 n/s which are used to both breed tritium and induce fission reactions. A breeding blanket is located between the superconductive central solenoid and the torus. Being composed of a lithium-lead eutectic mixture, it also acts as neutron shield. Instead, in the configuration studied here, the circular area around the torus (16 cm width) is half dedicated to further breed tritium while the rest is occupied by the fission blanket. The three sectors (~3.5 m radial extension) containing Pu+MA (60%)-Zr (40%) rods embedded in solid lead for nuclear transmutation (keff~0.94, P~200 MWth) are spaced out by two intermediate regions (~1.75 m radial extension) that can be used for in- ducing fast and slow transmutations. The results corroborate the interest for the RFP as a HFF reactor due to the simple design of thefusionreac- tor, the high accessibility to the blankets for maintenance and the multiple applications of the neutron flux (transmutation of plutonium, minor actinides and nuclear fission products, radiopharmaceuticals production) favoured by the blanket modularity.

There were only four magnetic confinement fusion concepts pursued internationally: tokamak, stellarator, pinch, and mirror. Since the early 1970s, numerous fusion designs have been developed for the four original and three new approaches: spherical torus, field-reversed configuration, and spheromak. At present, the tokamak is regarded worldwide as the most viable candidate to demonstrate fusion energy generation. Numerous power plant studies (>50), extensive R&D programs, more than 100 operating experiments, and an impressive international collaboration led to the current wealth of fusion information and understanding. As a result, fusion promises to be a major part of the energy mix in the 21st century. The fusion roadmaps developed to date take different approaches, depending on the anticipated power plant concept and the degree of extrapolation beyond ITER. Several Demos with differing approaches will be built in the US, EU, Japan, China, Russia, Korea, India, and other countries to cover the wide range of near-term and advanced fusion systems.

Selection of a Toroidal Fusion Reactor Concept for a Magnetic Fusion Production Reactor 1
Journal of Fusion Energy, Vol. 6, No. 1, 1987 Selection of a Toroidal Fusion Reactor Concept for a Magnetic Fusion Production Reactor 1 D. L. Jassby 2 The basic fusion driver requirements of a toroidal materials production reactor are consid- ered. The tokamak, stellarator, bumpy torus, and reversed-field pinch are compared with regard to their demonstrated performance, probable near-term development, and potential advantages and disadvantages if used as reactors for materials production. Of the candidate fusion drivers, the tokamak is determined to be the most viable for a near-term production reactor. Four tokamak reactor concepts (TORFA/FED-R, AFTR/ZEPHYR, Riggatron, and Superconducting Coil) of approximately 500-MW fusion power are compared with regard to their demands on plasma performance, required fusion technology development, and blanket configuration characteristics. Because of its relatively moderate requirements on fusion plasma physics and technology development, as well as its superior configuration of production blankets, the TORFA/FED-R type of reactor operating with a fusion power gain of about 3 is found to be the most suitable tokamak candidate for implementation as a near-term production reactor. KEY WORDS: Magnetic fusion production reactor; tritium production; fusion breeder; toroidal fusion reactor. 1. STUDY OBJECTIVES Section 2 of this paper establishes the basic requirements that the fusion neutron source must In this study we have identified the most viable satisfy. In Section 3, we compare various types of toroidal fusion driver that can meet the needs of a toroidal fusion concepts for which there has been at materials production facility to be operational in the least some significant development work.

The Fusion Energy Program: the Role of TPX and Alternate Concepts
Overview and Findings or over four decades the federal government has supported research to develop the power of fusion energy for com- mercial electric power production. Fusion proponents note that the supply of fusion fuels is virtually inexhaustible, and that environmental impacts may be far less extensive than those of energy supplies currently in widespread use. Widely her- alded experiments performed in 1993 and 1994 at the Princeton Plasma Physics Laboratory’s Tokamak Fusion Test Reactor (TFTR) produced unprecedented levels of fusion reactions and continued a trend of progress in fusion research. However, even the most optimistic proponents of fusion ener- gy note that many scientific, engineering, and economic chal- lenges remain to be met. Meeting these challenges sufficiently to construct a prototype commercial fusion powerplant may require several tens of billions of dollars in experimental facilities and research over the next several decades. This would require a con- siderable increase from the U.S. Department of Energy’s (DOE’s) current fusion energy program budget of $373 million, and a greater level of cost-sharing through international collaboration in fusion research and development.1 In 1987, the Office of Technology Assessment (OTA) con- cluded a major assessment of the fusion energy program and pub- lished the report Starpower: The U.S. and the International Quest 1 An additional $176 million is spent on inertial confinement fusion research as part of |1 DOE’s defense programs, much of which is relevant to fusion energy prospects. 2 The Fusion Energy Program: The Role of TPX and Alternate Concepts Physics Laboratory. This paper examines the history of TPX planning and the anticipated scientific, engineering, and institutional con- tributions of the TPX.

What is a reversed field pinch? D. F. Escande Aix-Marseille Université,CNRS, PIIM, UMR 7345, 13013 Marseille, France I. INTRODUCTION The reversed field pinch (RFP) is a magnetic configuration germane to the tokamak, that produces most of its magnetic field by the currents flowing inside the plasma; external coils provide only a small edge toroidal field whose sign is reversed with respect to the central one, whence the name of the configuration. Because of the presence of magnetic turbulence and chaos, the RFP had been considered for a long period as a terrible confinement configuration. Then strong enhancements were triggered in a transient way in the MST machine [1]. However, recently a change of paradigm occurred for this device. This was symbolically exhibited by the cover story of the August 2009 issue of Nature Physics: "Reversed-field pinch gets self-organized" [2].
