Fusion-fission hybrid systems (FFH) represent a coupling between a fusion device and a subcritical fission reactor driven by neutrons produced by fusion reactions. This kind of systems, in principle, can be useful for different purposes, for example, as energy amplifier or as nuclear waste burner. In this work, the preliminary characteristics and potentialities of a FFH based on a tokamak device characterized by high magnetic field ( B > 9 T) and high-density plasma ( n > 10 14 cm –3 ) have been evaluated. During the years high magnetic field compact tokamaks have been designed, built and operated. Thanks to their characteristics, such as compactness, high field and high density plasma, these devices can produce intense neutron fluxes, and therefore are good candidates to be incorporated in FFH while operating in a sub-ignited regime. An additional advantage is that their design is based on relatively simple existing technology. In this work, a coupling between a tokamak (operating in DD-mode) and a subcritical molten salt fission blanket has been proposed. Molten salt reactor could be adapted for this purpose and could help the hybrid system to increase its energy balance. A model with a molten salt fission blanket ( k eff = 0.92, P = 95 MW) instead of the lithium one, has been considered and studied in terms of neutronic evaluations. Presented preliminary numerical calculations based on a neutron Monte-Carlo code confirm the potentialities of the system.
聚变-裂变混合系统(FFH)是由聚变反应产生的中子驱动的聚变装置和亚临界裂变反应堆之间的耦合。这种系统，原则上，可以用于不同的目的，例如，作为能量放大器或作为核废料燃烧器。本文对基于高磁场(B > 9 T)和高密度等离子体(n > 10 14 cm -3)托卡马克装置的FFH的初步特性和潜力进行了评价。多年来，高磁场紧凑型托卡马克被设计、建造和运行。由于其致密、高场和高密度等离子体等特性，这些器件可以产生强烈的中子通量，因此是在亚点燃状态下工作时纳入FFH的良好候选者。另一个优点是它们的设计基于相对简单的现有技术。在这项工作中，提出了在托卡马克(运行在dd模式)和亚临界熔盐裂变包层之间的耦合。熔盐反应堆可以适应这一目的，并可以帮助混合系统增加其能量平衡。用熔盐裂变包层(keff = 0.92, P = 95 MW)代替锂包层模型进行了中子评价。给出了基于中子蒙特卡罗程序的初步数值计算，证实了该系统的可行性。

Based on the heuristically generalized perturbation theory (HGPT) adapted to subcritical systems [1], a procedure for online operational monitoring of the subcriticality level of a hybrid fusion-fission system in which an “external” neutron source is generated in a magnetically confined tokamak-type plasma is described. This procedure [2], commonly referred to as power control-based subcriticality monitoring (PCSM), consists of compensating of slow and small movements of a specialized control rod in the nuclear fission zone, previously calibrated using a standard procedure, with equally slow and small alterations of the fusion neutron source. PCSM is verified by solving the multi-group transport equation for the direct flux, as well as for the importance function, associated with normalized fission power [3], and a technique is proposed for modifying the fusion neutron source strength based on plasma compression/expansion. Plasma and confining magnetic field adjustments, needed to implement the PCSM, are estimated with due account of the 0-D-plasma power balance.
