Abstract

In assuring reactor safety with increasing target burnups, fuel behaviour in postulated accident conditions is receiving high attention. Within the OECD Halden Project in Norway, a programme of integral reactor tests in closely simulated light-water reactor loss-of-coolant accident (LOCA) conditions and with high-burnup power reactor fuel has been implemented [1]. The tests, designated as the IFA-650 series, now encompass seven abundantly instrumented in-pile tests and versatile post irradiation examinations. From the very beginning, VTT has been active in planning and qualifying the tests whereby the VTT GENFLO [2, 3] and amended USNRC FRAPTRAN codes, and their combination have been instrumental. In the following, success of some of the simulations with due consideration of the special features of the test arrangement are reviewed. In the Halden IFA-650 series, testing, post-test examinations, and related supporting and qualifying analyses continue.
