A new calculation method for radioactivity in a nuclear power plant is proposed. It can calculate radioactivity in shorter time than the conventional method with the same accuracy. The characteristic of the method is the effective usage of the radioactivity database applicable to the whole region of the plant. The database is provided for typical neutron irradiation conditions, cooling times and elemental compositions in a nuclear power plant by calculation with an isotope generation and depletion code such as ORIGEN-S. The effects of the method on both the time reduction and the calculation accuracy have been confirmed through application to an existing BWR in Japan. The calculation time can be shortened to around 1/4000 of the conventional method for a typical case.
