Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

A Monte Carlo code is developed in Visual Basic 6.0 for the study of radiation damage of pure metals irradiated by a neutron spectrum. At energies <10 MeV, development of cascades of elastic interactions of both primary neutrons and secondary recoiled atoms is incorporated. In a collision, kinetic energy given to an atom below or above the threshold displacement energy Ed (eV) is calculated along with the displacements. Displacements, defect production efficiency η, and damage energy Tdam are estimated to relate to the physical changes in the irradiated metal and to estimate the displacements per atom. The code is validated by determining the defect density on the surface of irradiated thin nickel foil and comparing with the hill-hock density of displaced atoms, using atomic force microscopy. In the case of irradiation of a niobium sample, stress-strain and I-V characteristics are measured before and after the irradiation by neutrons from an Am-Be source, and both stress and electrical resistance are shown to be enhanced after the irradiation.
