SINBAD ABSTRACT NEA-1517/82

Radiation field parameters for pressure vessel monitoring
in VVER-1000 using the NRI LR-0 experimental reactor (~1990)

 1. Name of Experiment:
    ------------------
    Radiation field parameters for pressure vessel monitoring in VVER-1000
    using the NRI LR-0 experimental reactor (~1990)


 2. Purpose and Phenomena Tested:
    ----------------------------
    The LR-0 benchmark data consist of neutron + photon spectra (WWER-1000 Mock-up) in several points 
    from the barrel simulator to the outer surface of Reactor Pressure Vessel and evaluated integral fluxes,
    space – energy indices, like the spectral indices and attenuation factors in measuring points.
  
    The space-energy distribution of the mixed neutron - photon radiation field has been measured over 
    Reactor Pressure Vessel (RPV) simulator thickness in the WWER-1000 engineering benchmark assembly 
    in the LR-0 experimental reactor with a multiparameter scintillation spectrometer. 
    The spectra have been measured before the RPV, in 1/4, 1/2, 3/4 of its thickness and behind the RPV simulator 
    in the energy range ~ 0.5 - ~ 10 MeV. The measurements were performed in the frame of the project 
    REDOS, WP 2 [1], 5th Frame Work Programme of the European Community 1998 - 2002.
  
    The presented measured data consists of integral data - ratios of integral photon and neutron fluxes 
    in measuring points and differential photon spectra in the measured fine structure
