In order to provide a reactor physics benchmark problem of burnup reactivity coefficients, experimental data of relationship between excess reactivity and accumulated thermal power acquired during experimental fast reactor JOYO MK-I duty power operation in the late 1970s have been evaluated and analyzed. All possible uncertainty factors were evaluated and quantified by utilizing knowledge obtained after the MK-I duty power operation and calculation results based on the latest reactor physics analysis methods. Meanwhile, the present evaluated data have been registered to the International Reactor Physics Benchmark Experiments Project (IRPhEP), with the expectation that this data will be widely used. In the present paper, the evaluation of nominal values and uncertainties is described with a focus on the measurement technique uncertainty which is a dominant uncertainty factor of the burnup reactivity coefficient.
