Experimental data of ground-state properties of exotic nuclei are important for nuclear structure studies and can test the reliability of nuclear mass models. The TRIGA-TRAP experiment is a double Penning-trap mass spectrometer used to perform high-precision measurements on long-lived transuranium isotopes and fission produced neutron-rich radionuclides at the research reactor TRIGA Mainz. Recently, a new cylindrical measurement trap was installed and characterized. After recommissioning, a mass measurement campaign started with several long-lived actinide isotopes. The data evaluation is still ongoing. The current status and first results will be presented.
