A 1430 MVA synchronous generator from a cancelled nuclear power plant has been installed and commissioned at Los Alamos National Laboratory LANL to be used as the pulsed power generator for physics experiments. The generator is mounted on a spring foundation to prevent dynamic forces from being transmitted to the substructure and into the ground. A 6 MW load-commutated inverter drive accelerates the machine from standstill to the maximum operating speed of 1800 rpm and from 1260 rpm to 1800 rpm between load pulses. The generator cooling method has been changed from hydrogen to air cooling to facilitate operation. A current limiting fuse, with a fuse clearing current of 90 kA, will protect the generator output against short circuit currents. An overview of the installation is presented. The paper also addresses the overload capability of the generator for pulsed loads.
