“…The tests with the FC under conditions of intense neutron and gamma radiation were carried out at the IBR-2M pulsed reactor at JINR [6,7]. During the tests the signals of the DAQ measuring chains with connected detector unit mockups were obtained at constant power levels and in the process of its change (ramp up and ramp down) of the reactor facility.…”

The Divertor nuclear flux monitor (DNFM) is one of the ITER neutron diagnostics. This diagnostic consists of the three same subsystems. Each subsystem concludes the detector module with fission chambers (FCs) and the data acquisition system (DAQ). To solve the task of the neutron flux measurements in the range of 7 orders of magnitude and 1 ms of time resolution the multidetector module is used. To confirm the possibility of the neutron flux measurements in a wide range using such a detector module and to evaluate the characteristics of the DAQ prototype a number of tests were carried out under conditions of the intense neutron radiation. The detector module and the DAQ, which are the prototype of the equipment planned for use on site were used for the tests. The tests were carried out at the plasma neutron diagnostic stand based on the NG-24M neutron generator and at the IBR-2 pulsed reactor of the Joint Institute for Nuclear Research. During the tests at the plasma neutron diagnostic stand the data for the calibration of the DNFM DAQ measuring channels were collected. During the tests at the IBR-2 pulsed reactor the signals from the measuring channels of the DNFM subsystem were obtained while the neutron flux was changed. This report shows the test results and the subsystem calibration techniques.

“…In 2007, the reactor reached the service life limit on fuel burn-up and fluence on the reactor vessel and was shut down for modernization and replacement of the primary reactor equipment. The main objectives of the modernization were to increase the safety, reliability and experimental possibilities of the reactor for the next 25 years of operation [3]. By 2010 the installation of new equipment was completed and was followed by a successful power startup.…”
