摘要： The invention relates to a method for producing a radionuclide product B. The method comprises the following steps: Providing a target comprising an amount of a nuclide A, providing a γ beam and irradiating the target by the γ beam and thereby transmuting at least a portion of the amount of the nuclide A into the product B. Providing the target comprises selecting a nuclide A, such that A is transmutable into product B by a γ induced nuclear reaction. Moreover, providing the γ beam comprises providing a γ beam by Compton back- scattering of laser light from an electron beam.

摘要： A linear accelerator, preferably of the monochromatic type, accelerates electrons to an energy of about 10 MeV which are directed onto a high Z target such as tungsten to generate gamma rays which are directed onto the fuel material such as U238 which results in the (ηf) reaction, thus releasing about 200 MeV. A reactor built according to this principle requiring an accelerator driven by 1 MW will develop about 20 MW of power. The reaction is not self-sustaining and stops when the beam is turned off. This accelerator driven reactor may be used to 'burn-up' spent fuel from fission reactors, if simply operated at 10 MeV. The photo-fission results in typical spent fuel waste products such as Cs?137 and Sr90¿ which undergo photodisintegration by the (η,n) reaction resulting in short lived or stable products.

摘要： The invention provides a radionuclide production system and a radionuclide production method capable of efficiently producing a radionuclide by a small, lightweight, and highly safe device. A radionuclide production system (100) is a radionuclide production system for producing a radionuclide by irradiating a liquid containing a raw material nuclide with bremsstrahlung radiation, the radionuclide production system including: a circulation path (10) configured to allow a liquid (11) containing a raw material nuclide to circulate; and a radiation generation unit (20) configured to generate bremsstrahlung radiation (22) to irradiate the liquid (11). A metal member (50) containing a pure metal of a platinum group or an alloy of the platinum group is provided at an upper portion in the circulation path (10). In a radionuclide production method, the raw material nuclide contained in the liquid (11) is transformed to the radionuclide by irradiating the liquid (11) with the bremsstrahlung radiation (22) while circulating the liquid (11) containing the raw material nuclide in the circulation path (10), and oxygen and hydrogen generated due to radiolysis of the liquid (11) are removed by a recombination reaction with a metal member (50) formed of a pure metal of a platinum group or an alloy of the platinum group at an upper portion in the circulation path (10).
