Non-centrosymmetric single-beam accelerator driven subcritical reactor

Abstract

The invention discloses a non-centrosymmetric single-beam accelerator driven subcritical reactor. The single-beam accelerator driven subcritical reactor comprises a proton beam, a spallation target, a fuel area and a radiation shielding layer, the radiation shielding layer wraps the periphery of the fuel area, the spallation target is located at a non-central position in the fuel area, and is inserted into the fuel area in a penetrating manner along the axial direction, and a proton beam is inserted into the spallation target along one axial end of the spallation target. According to the single-beam accelerator driven subcritical reactor provided by the invention, the proton beam and the spallation target are arranged at the non-central position of the fuel area, and under the same parameters, the neutron multiplication factor of the single-beam accelerator driven subcritical reactor provided by the invention is improved by 0.02399 compared with that of a centrosymmetric ADS; and the integral energy efficiency of the reactor is improved under the condition that the charging amount is not increased, high economic advantages are achieved, the refueling operation of the refueling mechanism is obviously simplified, engineering implementation is simpler, more convenient and safer, and the economical efficiency is better.

Description

Technical field[0001]The present invention relates to the field of nuclear reactor, in particular a unintext-symmetrical single-stream accelerator drive secondary pile.Background technique[0002]In modern times, fossil energy has always dominated the goal of energy, with the depletion of fossil energy and its increasing environmental damage, the traditional capacity mode gradually tends to weaken. The nuclear energy is a mainstream as a new, high-energy density type clean energy. However, during the development of nuclear energy, the nuclear waste problem is a worldwide problem. To solve this problem, the nuclear industry proposes the concept of accelerator driving secondary pile (ADS). The ADS consists of a proton accelerator, a dispenser in water target, and a secondary core, and the accelerator accelerates heavy-band particles (such as protons, helium ions) to bombard the heavy metal target to generate a slime neutron, and then transform nuclear waste.[0003]At present, the mainstr...
