Construction at Rostov Unit 4 is in progress, with 80% of pipelines already installed. All the large-size machinery in the reactor island has been mounted, and the workers are now busy fitting pipes. First, they are going to install systems to be used in December for non-pressure tests –pre-washing the pipes and equipment of the reactor island with desalinated water. Non-pressure tests mark the beginning of preparations for the reactor start-up. Unit 4 is scheduled to go critical in 2017.
