Although it has been accepted for some time that the damage criterion for impact of falling objects is the velocity at impact, there has been little acceptance of the view that velocity at impact determines damage in radial impacts such as occur in charge/discharge of fuel elements or gas induced vibrations in pins in elements. Most A.G.R. tests to date have been based upon interpretation of results from accelerometers to establish acceleration or deceleration values at impact. It is suggested that this practice is misleading. Variation in material properties due to temperature changes affect the stresses set up by impact. This effect is considered in relation to graphite and stainless steel.
