From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

The 30-deg white neutron beam at the Research Center for Nuclear Physics (RCNP) cyclotron facility has been characterized as a probe suitable for testing of single-event effects (SEE) in semiconductor devices in the neutron energy range from 1 to 300 MeV using the 392-MeV proton incident reaction on a 6.5-cm-thick tungsten target. The neutron spectrum obtained by time-of-flight measurements reproduced the terrestrial neutron flux distribution at sea level, and neutron intensity increased by a factor of 1.5 × 108 became available. The average neutron intensity and spectrum in the energy region from 10 to 100 MeV at RCNP were almost the same as those at the Weapons Neutron Research (WNR). The calculated RCNP neutron flux using Particle and Heavy Ion Transport code System (PHITS) generally agreed with the measured RCNP data within a factor of 2. The neutron density per pulse at RCNP, which is around 500 times lower than that for WNR, has the advantage in reduction of the pileup probability of single-event transient currents and false multiple-bit upsets. Such conditions at RCNP are suitable for accelerated SEE testing to get meaningful results in a realistic time frame.
