Research reactor protection and neutronic experimental measurements:
Most research reactors in France rely on Photonis fission chambers and boron-lined proportional counters. Jules Horowitz Reactor (JRH) is the last of a long list to benefit from Photonis detector know-how. Photonis detectors are also compatible with upgrade or retrofit of TRIGA type reactors. The small form factor of Photonis detectors help answering the challenges linked to the construction of lower power reactors such as SMRs (Small Modular Reactor).
