estimation of the error of functionals calculation results of the neutron flux onto the wwer 1000 reactor pressure vessel

It is shown that systematic calculation errors of functionals of the neutron flux onto WWER 1000 reactor pressure vessel are pseudorandom. The error of the neutron flux functionals is estimated on the basis of this fact and the data obtained with the reactor LR 0 benchmark and with the results of dosimetry measurements near re-actor pressure vessels.
