Stainless steel contains iron and nickel—important materials in nuclear power reactors and possible constituents of the materials used to construct nuclear test devices or their supporting structures.8 9 During nuclear weapons tests, stable Fe and Ni isotopes are neutron activated, giving rise to radioactive Fe and Ni along with fission products. In nuclear power plants, moreover, stable Fe and Ni isotopes are released from stainless steel through corrosion, become activated, and are transported to different parts of the reactor system. 

Regenerative biofilms have been tested under industrial conditions in the chill water system at the University of California, Irvine (UCI) and at Three Mile Island Nuclear Power Station (TMI) using EIS [123, 124]. Reciprocal polarization resistance (l//fp), considered to be directly proportional to the corrosion rate, was compared as a function of time for preexposed mild steel samples tested in unaltered (standard) service water and samples tested in service water inoculated with protective bacteria. Substantial differences in... 

This method found application also in the field of the vitrification of hazardous waste, namely in the determination of optimal conditions for immobib-lization of the waste containing Sr and Cs from nuclear power plants, and in testing the durability of this glass towards hydrolytic corrosion [29,30]. 

Corrosion of metals and alloys—Aqueous corrosion testing of zirconium alloys for use in nuclear power reactors... 

Large efforts were given to assess compatibility of refractory alloys with liquid Li in space nuclear power applications. The compatibility issue has commonality with that of V-alloys with liquid Li. Those alloys which easily oxidize may have the benefit of using Li as a coolant because Li may remove impurity O in the alloys. However, high O level in the matrix of the refractory alloys may induce reduction corrosion [75]. Addition of O getters such as Hf, Zr, or Y were recommended for Nb-alloys [76]. Corrosion in liquid Li proceeds by dissolution of elements followed by mass transfer and impurity pick-up/extraction. Both processes are highly influenced by the circulation condition (delta T and flow distribution) and impurity levels of both Li and the alloy being tested.
