A constitutive equation of irradiation creep and swelling under neutron irradiation.

Radiation Effects in Metals: Void Swelling and Irradiation Creep

Until about 1967 the most detrimental radiation effect expected to be suffered by the stainless-steel cladding of the fuel elements of the projected liquid-metal-cooled fast breeder reactor (LMFBR) was embrittlement due to exces­ sive hardening at low temperatures or helium agglornrration at grain boundaries at high temperatures, These problems, however, were at least qualitatively understood, ...

UWFDM-883 Irradiation Behavior of Bonded Structures: Impact of Swelling-Creep-Stress Relationship

Radiation damage will be a major key point in the design of the many duplex components in fusion reactors. There is a substantial amount of available data showing that stress plays a major role in the onset, and possibly the rate, of void growth in austenitic stainless steels. There is also a strong support for models which predict a coupling of swelling and creep through the stress environment...

Neutron irradiation of SmFeAsO1−xFx

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...

Thermal Diffusivity of Ceramics During Neutron Irradiation

Radioisotopes produced by neutron irradiation of food.

The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...
