Sinc巳 there are both PWRs and CANDU reactors in China , a plan was brought forward to use R U reprocessed from PWR spent fuels in CANDU reactor in a form of NUE type firstly , which is combination of RU and depleted uranium (DU) and is neutronically equivalent to natural uranium. For this fuel , the demonstration test was conducted in Qinshan CANDU unit 1 , to ob tain the experiences of RU manufacturing and operating and to provide technical support to NUE fuel full
