Joint NEA project performs high-burnup test
An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

A redetermination of the age τ (= ⅙ 〈r2〉) for neutrons of indium-resonance energy (1.46 ev) from a point U235 fission source is reported. Foils were irradiated in a geometrically simple arrangement in the Penn State Reactor pool, and counted in a standard manner. The value obtained, τ = 27.3 ± 0.9 cm2, is in better agreement with current theory than those from previous measurements. The spatial distribution found here differs most markedly from those observed in previous experiments by having a larger slope in the region within a few centimeters of the source.
