Sugino, Kazuteru; Takeda, Toshikazu*

Reduction in uncertainty of Minor Actinide (MA) cross-section data is indispensable for a development of the transmutation technology, which is represented by the study on MA transmutation core concept. One of the most effective measures to attain the desire is to utilize MA irradiation test data with cross-section adjustment technique. For this purpose, most of the available integral data containing MA contributions have been compiled. This paper describes an investigation on improvement of MA cross-section data using the cross-section adjustment method. In order to enhance the reliability of the adjustment, two or more independent MA irradiation test data, which are represented by those measures in Joyo, PFR and Phenix, are utilized.
