However, it is known that the decay heat predicted by nuclear fuel burn-up calculations is uncertain because of uncertainty of nuclear data employed in the calculations. If the decay heat uncertainty can be reduced, the safety margin of the predicted decay heat can also be reduced, and feasible design ranges of various types of equipments related to the decay heat can be extended. In the present study, we use the nuclear data adjustment method for the decay heat uncertainty reduction with several types of the experimental data. As a result, we clarify that the decay heat uncertainty with short- and long-term cooling periods can be reduced by this method with appropriate experimental data.Taylor & FrancisJournal Articleapplication/pdfhttp://hdl.handle.net/2115/68242https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/68242/1/report_kawamoto.pdf0022-3131Journal of nuclear science and technology5422132222017-02enginfo:doi/10.1080/00223131.2016.1238785This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of nuclear science and technology on Feb 2017, available online: http://www.tandfonline.com/10.1080/00223131.2016.1238785.author
