Results of the pilot use of EES - SG stand at VVER440 in Jaslovske Bohunice

Popis výsledku v původním jazyce

Corrosion problems of components of nuclear power plants play an important role both in the field of operational safety and the concept of prolonging the life of these energy devices. In case of steam generators, where the purity of feed water of operated units approaches the theoretical values, localities of occluded volumes with heat flux are regarded as critical places in terms of corrosion. In these discrete areas relatively rapid concentration process of trace impurities of feed water takes place.As a result, high local concentrations exist providing thus appropriate conditions for the initiation of corrosion cracking of austenitic stainless steel components. Localities threatened by corrosion under this mechanism, i.e. structural crevices: tube? collector (tube sheet), tube ? tube support plate, crevices under deposits on the free span of tubes, are during operation of steam generators completely inaccessible and the nature of crevice environment can be considered only on the b
