Abstract

Japan Atomic Energy Agency (JAEA) has modified the Static Experimental Critical Facility (STACY) to a heterogeneous system using fuel rods in order to obtain criticality characteristics of fuel debris. Thermal power measurement was required for the calibration of a power meter system in the modified STACY in order to conduct a series of performance inspections and operation. We measured the thermal power using the modified activation method that combined MVP and PHITS code because neutron flux distribution cannot be measured experimentally. Four operations were conducted for the thermal power measurement. The power meter was calibrated by using three operational data and tested with one operational data. It was found that the calibration of the power meter system was successfully agreed within 3% with the results measured by the activation method.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
