General objectives

      Establishment of localized corrosion mechanisms which has as effect the deterioration of structural components of NPS primary and secondary circuit.

      Elaboration of some models that can predict in time evolution of some localized corrosion type specific to exploitation conditions of NPS circuits.

      Establishment of some remedies that conduct at the diminishing of localized corrosion of equipments from the nuclear installations using some chemical additives or corrosion inhibitors.

    The specific objectives are:

      Testing at the localized corrosion using several testing methods of some structural materials in the specific working conditions in nuclear station to identify the corrosion mechanisms.

      Identifying the main physical-chemical factors that can influence the localized corrosion behavior and especially SCC with the aim to establish some measures (remedies) that diminish the negative effects of this degradation type.

      Use of more complementary physical-chemical investigation methods to characterize more exacts the corrosion behavior of several interesting structural materials.
