Westinghouse has signed off contracts for two more AP1000 containment vessels. Chicago Bridge & Iron (CB&I) will manufacture the two components, which each measure some 36 metres in diameter and 65 metres in height, for a fee of $150 million. CB&I said design work would begin immediately with construction to follow during next year, the first vessel being complete in 2015, the second in 2018. It was not revealed which planned nuclear units the components are destined for - CB&I narrowing it down only to "the southeastern US" where seven pairs of AP1000s are currently planned. An identical contract was announced in late October for deliveries in 2014 and 2015.
