Reactor Damage in Pure Metals

Abstract: By relocating the fuel in the vicinity of a liquid helium cryostat located in the Oak Ridge Graphite Reactor it has been possible to separate the thermal and fast components of the reactor neutron flux. Studies of the radiation damage effects arising from each type of flux have been made. It has been found that an appreciable fraction of the reactor damage in several metals arises from thermal neutrons. The effect results from the recoil of an atom from the (n,γ) reaction at the time of thermal neutron capture… Show more

“…A major feature which distinguishes fast neutron damage from thermal neutron damage (Fig. 13) is the strong reduction of Substage I E and a significantly higher damage retention above Stage I [125,128]. Because of the segregation of vacancies and interstitials, this general annealing behaviour of Stage I is expected.…”

“…(4) In that discussion it was assumed that the transmuted atom resides at a normal lattice site. It is pointed out, however, that if a metal has a tendency for damage to be produced by a displacement rather than a replacement process, then the capturing atom may become a radioactive interstitial.…”
