Correlations between calculated surveillance dosimeter activities and pressure vessel fluxes in the Arkansas Nuclear One Unit 1 reactor
An illustration of the magnitudes of the cross-correlations between cavity dosimetry and fluxes at an important location in the pressure vessel is given for the case of the Arkansas Nuclear One Unit 1 reactor and provides a correspondence with previously reported flux covariance reduction factors. These correlations are seen to extend over energy regions far wider than would be intuitively expected because of the highly correlated nature of the calculated pressure vessel fluxes themselves, thus enhancing the range of pressure vessel flux information that is provided by the dosimetry. Finally, the high degree of correlation between the cavity dosimeters and pressure vessel fluxes shows that ex-vessel dosimetry can be successfully applied to reactor pressure vessel damage surveillance programs.
