Manipulation of radioactive isotopes with ion traps has opened new opportunities in nuclear spectrometry. The applications employed so far include high-precision mass measurements as well as many other applications where high sensitivity and purity is obtained through ion manipulation in Penning and Paul traps. In my talk I will discuss some recent experiments and mass measurements related to nuclear structure studies near the magic neutron numbers 50 and 82 , studies of rapid proton capture process near 100Sn , precision measurements of nuclear beta decays for electroweak physics  and accurate Q-value measurements for double beta decay and electron capture experiments .
