A secondary beam line (GIRAFFE) at the Beijing Tandem accelerator lab was constructed for yielding low energy secondary beams. The current progress on the study of nuclear astrophysics and nuclear structure is presented. Up to now, We have carried out measurement of 7Be(d, n) 8B, 11C(d, n)12N, 8Li(d, p)9Li, and 6He(p, n)6Li reactions. The proposed Beijing radioactive nuclear beam facility (BRIF ) and its current R&D progress are briefly introduced. This facility is based on the existing HI-13 tandem accelerator. A proton cyclotron will be built to provide 100 MeV 200 μA proton beam, together with an ISOL system and a super conducting heavy ion LINAC. By this facility, intensity of order of 109 particles/s radioactive nuclear beams for mass up to A=120 will be produced.
