Analyzing the causes for the dispersion of the fast reactor spent fuel rod cladding properties [PDF]

open access: yesNuclear Energy and Technology, 2019
The swelling, corrosion and high-temperature embrittlement behavior of the fast-neutron sodium-cooled reactor standard and test fuel rod claddings was studied following the operation up to a damaging dose of 55 to 69 dpa.

Ductile B2 Intermetallics‐Driven Strength‐Ductility Synergy in Heterolaminated Multi‐Principal Element Alloys

open access: yesAdvanced Science, EarlyView.
Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Irradiation embrittlement mitigation

open access: yes, 1995
Neutron irradiation affects the material properties, and hence the structural integrity, of reactor pressure vessels in nuclear power plants. Mitigation of irradiation damage is one of the major issues within nuclear plant life management. An overview is given of proposed and utilized mitigation methods. Low-leakage loading schemes are commonly used in

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

open access: yesJournal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...

Grain size reduction strategies on Eurofer

open access: yesNuclear Materials and Energy, 2018
One of the options currently taken into account for the realization of the first DEMO reactor is the “water-cooled blanket”. This option implies a minimum irradiation temperature for the blanket material in the range of 280–350 °C.
