For the future energy system, we propose a new closed nuclear energy cycle system, which consists of an accelerator-driven external neutron source, a ceramic reactor and an extend AIROX reprocessing. The attractive features of this system are as follows. （l） The operating mode of the reactor is a combination of subcritical mode and critical mode. initially, the reactor would be driven by the accelerator external neutron source in subcritical mode. A few years later, the reactor would reach the critical mode, and then would operate for a long time. （2） Nuclear fuels, coolants, and structure materials in the ceramic reactor core are made up of ceramic with excellent thermodynamics properties and neutron performance. Therefore, the ceramic reactor has extremely inherent safety, good breeding performance and high power generation efficiency. （3） Fuel reprocessing uses an extend AIROX reprocessing, which is a simple high-temperature dry process and rarely involved in chemical process. In this reprocessing, only most of fission products are separated. Other isotopes, including uranium isotopes, transuranic nuclides and long-lived fission products, would re-enter the reactor as new fuels. Therefore, this closed nuclear energy system could be known as ADANES, short for Accelerator-Driven Advanced Nuclear Energy System, which can greatly improve the utilization rate of nuclear fuels, enhance the nuclear safety, reduce the nuclear proliferation and become a sustainable and low-carbon energy supply for thousands of years.

In 2005, the commissioning totally 60 days for the CSR main ring was performed, the first-turn and stored C6+ beam (with lifetime more than 10 s) in the CSRm were achieved with≈7 MeV/u 12C4+ as the injection beam. Many technical progresses have been made before realizing the storage of ion beam, such as the control of magnet power supplies, the improve-

IMP & HIRFL Annual Report 2004年 10-11页

作者： zhan wenlong Director of IMP Vice Director of NLHIAL

In 2004, the HIRFL accelerator complex was fully in operation after the shut-down for upgrading. A series measurements and tests indicate that the new rebuncher has achieved the designed requirements. The preliminary test demonstrates that the beam intensity of SSC for energy less than 30 MeV/u could be improved by a factor two with the rebuncher, but for the higher energy beam the enhancement of the beam intensity is smaller due to not enough bunching voltage. The renovation of about 300 sets of power supplies at the HIRFL has been completed. A high stability of 5×10-6 for the main power supplies of SSC was reached. To deliver a more intense pulsed beam, a chopper (pulse width 1-18 ms, pulse period 4.75-17 s) designed particularly for the CSR injection was used at the axial injection beam line of SFC. The maximum beam intensity of 13 eμA for 7 MeV/u 12C+4 was obtained.
