In 2010, the commissioning of in-hospital neutron irradiator (IHNI) and its systems were completed. The operation with power started since then. The IHNI has operated by 99 times. The release of total energy is 1 832.42 kW·h with the corresponding integral neutron flux of 2.198 9×10¹⁷ cm^-2. The test operation data shows that the operation values of IHNI and its relevant systems are smaller than the limited value, which manifests that IHNI is safe and reliable.
