    Gamma and neutron radiation fields above the reactor pool of the LVR 15 research reactor

  • Original language description

    The LVR-15 reactor is a light water research reactor, which is situated in Research Centre Rez Ltd, Husinec-Řež near Prague. The reactor operates as a multipurpose facility with maximal thermal power of 10 MW. Roughly six meters thick water layer of reactor pool is above the reactor core. About one meter above the pool surface there is the reactor head. During reactor operation, relatively high level of radiation is present in the space between the pool surface and the reactor head. This space is closed for workers during reactor operation but some objects sensitive to radiation damage (e.g. cameras, cables) can be used here and therefore it is important to know the radiation situation in this space. The radiation originates from the reactor core, radionuclides present in primary circuit water, activated parts of the reactor and from different types of secondary reactions. Main components of the radiation are gamma photons and neutrons. Neutron and gamma fields are not homogeneous in this space due to the different types of the vertical channels. The measurement of fields was made in four points under the reactor head. Gamma radiation dose rate was measured with alanine detectors. Fluence rate of thermal, epithermal and fast neutrons was measured with different types of activation and track detectors. Boxes with set of detectors were fixed in their four measuring points during one reactor cycle (20 days). In the paper, description of measurement and data evaluation, and result values of gamma dose rate and neutron fluence rate are given.
