Achievements of HTTR second driver fuel elements assembly working

Tomimoto, Hiroshi; Umeda, Masayuki; Nishihara, Tetsuo; Iyoku, Tatsuo

UTNL-R-0471, p.11_1 - 11_9, 2009/03

The first driver fuel of the HTTR (High Temperature Engineering test Reactor) was loaded in 1998 and the HTTR reached first criticality state in the same year. The HTTR has been operated using the first driver fuel for a decade. HTTR reactor core consist of twelve kinds of enriched uranium fuel elements. Fuel rods were designed for avoiding fuel rod false loading because fuel rods number is 4770, and it was considered on handling. Reception of fuel rods, assembling of fuel elements and storage of second driver fuels in the fresh fuel storage rack in the HTTR were started since June, 2008. Pre-service inspection was finished. And the second driver fuel assembling was completed in September, 2008. This report describes concerns of fuel handling on assembling and storage work for the HTTR fuel elements.
