the results of the forecasts is shown in Fig. 5.39. Figure 5.39a shows the
function N det for the cladding of one of the casings of the VVER-1000
reactor constructed on the basis of the inspection results. The following
values of the parameters are determined from the condition of maximal
proximity of the function [5.21] to the experimental data
A = 1.482 mm 1;17 ; n = 2; 17, a = 0.034 mm -1 .
