We propose a method for fast initialization and quantum control of a 15N nuclear spin in diamond nitrogen-vacancy (NV) centers using non-selective microwave pulses. We demonstrate that the nuclear spin states can be initialized in 130 ns, which is an order of magnitude faster than the conventional methods. Our result may contribute to the development of quantum devices using electron and nuclear spins in NV centers.
