The forthcoming JET DT campaign represents a unique possibility for validating the suite of neutron diagnostics of a DT burning plasma. In particular, issues such as operation at high 14 MeV neutron flux, availability, long term stability, remote control will be important. This work will present the state of the art of the 14 MeV neutron diagnostics systems of JET, with special emphasis on the major enhancements that have been carried out in the last ten years. The plasma parameters that can be provided by the entire suite of neutron diagnostics will be presented: i) time resolved 14 MeV neutron emissivity/fusion power (by absolute neutron flux monitoring); ii) the neutron spatial emissivity (neutron camera); iii) information on the fuel ion distribution (high resolution neutron spectrometers). Finally, the benefit for ITER and DEMO of experience acquired at JET will be discussed.
