Abstract
Research Reactor can provide a platform for advanced reactors’ fuel and material irradiation test, medical isotopes production and neutron science research, which plays an important role in nuclear energy and technology domain. Nowadays, most of research reactor in worldwide are reaching the retirement and decontamination stage. For the increasing demand of the material irradiation and medical isotopes in the world, several new and advanced research reactors should be constructed to replace the void in the future. Differed from the design scheme of the traditional PWR, that of research reactor focus on increasing the power density as high as possible for the huge amount of neutron flux. According to the full reference of the existing advanced research reactor, this article starts a reactor physics design scheme and illustrate a unique reactor physics design. The neutron flux, length cycle and instrument flexibility of this design are better than the reference design.
