“…In the 2000s, many in-depth studies on Ni-Cr-Mo-Gd alloys for neutron shielding materials were conducted in the United States for the Yucca Mountain Project [ 129 ]. Initially, Dupont et al [ 130 ] investigated the effects of Gd on the solidification behavior and weldability of a Ni-Cr-Mo alloy and discovered that the Ni-Cr-Mo-Gd alloy solidified in a way comparable to a binary eutectic system.…”

With the rising demand for nuclear energy, the storage/transportation of radioactive nuclear by-products are critical safety issues for humans and the environment. These by-products are closely related to various nuclear radiations. In particular, neutron radiation requires specific protection by neutron shielding materials due to its high penetrating ability to cause irradiation damage. Herein, a basic overview of neutron shielding is presented. Since gadolinium (Gd) has the largest thermal neutron capture cross-section among various neutron absorbing elements, it is an ideal neutron absorber for shielding applications. In the last two decades, there have been many newly developed Gd-containing (i.e., inorganic nonmetallic-based, polymer-based, and metallic-based) shielding materials developed to attenuate and absorb the incident neutrons. On this basis, we present a comprehensive review of the design, processing methods, microstructure characteristics, mechanical properties, and neutron shielding performance of these materials in each category. Furthermore, current challenges for the development and application of shielding materials are discussed. Finally, the potential research directions are highlighted in this rapidly developing field.

“…Alloying elements added for various purposes can affect the corrosion behavior. For example, a nickel-based alloy (Ni-15Cr-15Mo-2Gd) containing gadolinium for increased neutron absorption, exhibits a corrosion rate of less than 0.1 μm/year for a 2-year exposure to a simulated storage environment [36]. However, the corrosion behavior of this alloy is inferior to that of 304 stainless steel due to the dissolution of Ni 5 Gd intermetallic particles during corrosion.…”

One of the challenges for the continued use and expansion of nuclear power generation is the disposal of radioactive waste materials. The long lifetimes require the identification of stable geological formations with non-aggressive environments, combined with engineered multi-barrier containment systems. In this paper, the corrosion behavior of alloys used in containment systems for storage of nuclear waste in geological sites will be reviewed.
