On the recommendation of the International Atomic Energy Agency's (IAEA's) working group on gas-cooled reactors, the IAEA has established a coordinated research program (CRP) on the validation of safety-related physics calculations for low-enriched uranium (LEU)-fueled high-temperature gas-cooled reactors (HTGRs). The objective of the CRP is to provide safety-related physics data for LEU-fueled HTGRs for use in validating reactor physics codes and methods used by participating countries for analysis of their designs. At present, the main activities within the CRP are being carried out by the international project now under way at the PROTEUS critical facility at the Paul Scherrer Institute in Villigen, Switzerland. Within this project, critical experiments will be conducted for HTGR-LEU systems to determine core reactivity; flux and power profiles; reaction rate ratios; worth of control rods, including reflector control rods; worth of burnable poisons; and the effects of water ingress on these parameters. Of particular interest are quality-assured (benchmark type) measurements of the worth of control rods located in the graphite reflector. Two independent techniques have been selected for this purpose; the pulsed neutron source (PNS) and the inverse kinetics methods.
