Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] The invention relates to a deep negative feedback reactor based on an accelerator-driven subcritical clean nuclear energy system, which includes a target area, a fast spectrum area, and a deep negative feedback area. Using the fast spectrum region for fuel breeding and nuclear waste transmutation, the negative reactivity of uranium zirconium hydride is used to compensate the reactor power change caused by the accelerator beam. Such as figure 1 As shown, a deep negative feedback transmutation reactor core based on an accelerator-driven subcritical clean nuclear energy system, including the target area A of the transmutation component, which is composed of proton tubes and target materials. Accelerated high-energy protons enter the target area and react with the target material to cause spallation Reaction to produce high-energy neutrons;...

Abstract

The invention discloses a deep negative feedback transmutation reactor core based on accelerator driven subcritical clean nuclear energy system and belongs to the field of nuclear reactors. The reactor core comprises a target area (A), a quick spectrum area (B) and a deep negative feedback area (C). According to the deep negative feedback transmutation reactor core provided by the invention, the problem that the reactor is instable in power because the accelerator beam is instable under the conventional technical conditions can be solved, the reactor can stably operate under different subcritical depths, and the reactor has extremely high inherent safety due to a large fuel Doppler coefficient.

Description

technical field [0001] The invention relates to the field of reactor equipment and belongs to the field of reactor engineering technology, in particular to a deep negative feedback transmutation reactor core based on an accelerator-driven subcritical clean nuclear energy system. Background technique [0002] Accelerator-driven subcritical clean nuclear energy system (is one of the most effective means of transmuting nuclear waste in the future. The protons are accelerated through the accelerator, and the spallation reaction with the target in the reactor produces high-energy neutrons, and the nuclear waste is transmuted into short-lived The radioactive nuclides or stable nuclides are expected to achieve zero radioactive pollution to the environment by the reactor, and the accelerator-driven subcritical clean nuclear energy system has the function of power output. [0003] Whether the beam flow of the accelerator is stable will have an important impact on the power of the rea...
