Solving embrittlement is a multi-billion-dollar question. Why hydrogen causes steels to become brittle and crack is the great conundrum of engineers and researchers looking to develop large-scale transport and storage solutions for the hydrogen age – an era which Australia hopes to lead by 2030.
@steter Neutron embrittlement usually affects the metals in the reactor vessel.
"Neutron irradiation embrittlement could limit the service life of some of the reactor-pressure vessels in existing commercial nuclear-power plants. Improved understanding the of the underlying causes of embrittlement has provided regulators and power-plant operators better estimates of vessel-operating margins. This article presents an overview of embrittlement, emphasizing the status of mechanistic understanding and models, and their role in increasing the reliability of vessel-integrity assessments."

Improved understanding the of the underlying causes of embrittlement has provided regulators and power-plant operators better estimates of vessel-operating margins. This article presents an overview of embrittlement, emphasizing the status of mechanistic understanding and models, and their role in increasing the reliability of vessel-integrity assessments. Finally, a number of outstanding issues and significant opportunities, including a new fracture-toughness master-curve method, are briefly described.

"Japan's Diet enacts bill to extend nuclear power plant operation beyond 60 years"
Look up "bathtub curve" of risk

This from @philipsargent is worth a read on #Embrittlement.
To be clear, I’m against ##Hydrogen for heating and most transport in line with @mliebreich #HydrogenLadder, that is a very useful resource for applications.
