But the "negative learning" was exactly because they abandoned the standardized approach.
"Conversely, the gradual erosion of EDF’s determination to
standardize (caving in to proposals of numerous design changes
in the wake of the ‘‘frenchifying’’ of the Westinghouse de-
sign—the P’4 reactor series—and above all to the new N4 reactor
design pushed by the CEA), as well as the abrupt slowdown of the
expansion program after 1981, paved the way towards a gradual
demise of the French success model, as borne out in lengthened
construction times and ever higher cost escalation towards the
end of the program (cf. Section 4 below)."
