WWER-1000 core loading characteristic influence on irradiation conditions of surveillance specimens and reactor pressure vessel [PDF]
Irradiation conditions of WWER-1000 surveillance specimens and reactor pressure vessel are comparative analyzed for various core loadings. It is proved that the fluences onto specimens don't correlate with ones onto pressure vessel.
