Areva's (CEI.FR) partnership talks with Vinci (12548.FR) confirm its CEO's determination to keep Areva as a standalone company, which could make Areva less interesting for a potential suitor, Bouygues (12050.FR), says Dexia. Adds, Areva would find a strong partner in Vinci and could bolster growth in its back-end division where most of the revenues still come from fuel treatment and recycling (81%), and only 6% from the nuclear cleanup. Reiterates add rating and EUR840 target price on Areva. Areva shares +2.3% at EUR760, Vinci +2.3% at EUR47.55. (LAF)
