JOYO MK-III Performance Test at Low Power and Its Analysis

Performance test at low power has been carried out in the experimental fast reactor JOYO for the upgraded MK-III core. In the test, several neutronics characteristics, such as the control rod worth, the control rod shadowing effect, the excess reactivity and the isothermal temperature coefficient have been measured. For the analysis, a deterministic standard calculation method developed by Japan Nuclear Cycle Development Institute was used. Calculated values agreed well with the experimental ones within 0.55%Δk/kk’ in the excess reactivity, 4% in the control rod worth and 3% in the isothermal temperature coefficient.
