    Abstract

    The basic effects of irradiation, such as transmutation re-actions, hardening, void formation and high temperature embrittlement are reviewed. Testing for these effects takes the form of pre-post testing as well as in-reactor observations. Pre-post testing consists of measuring a property out-of-reactor, and measuring the same property after the material has been exposed to the neutron environment. Although changes in properties of a material can be determined before and after irradiation, the influence of a neutron flux on rate processes such as creep must be determined in-pile.

    Characterization of the reactor environment including neutron dosimetry and temperature measurements are discussed, and examples of predictive testing of materials for reactor fuels, cladding, components and pressure vessels are reviewed.
