On January 2, 2013 at 9 am 45 points, by the United States EMD company design and manufacture of the world the first table AP1000 nuclear reactor coolant pump (hereinafter referred to as the main pump) - the third generation of nuclear power project studies based on three nuclear power plant unit 1 first one main pump arrived in three nuclear power terminal, and successfully completed discharging work, safe arrival storage location.

      AP1000 nuclear main pump is nuclear steam supply system in addition to the main loop control rod drive mechanism outside the only active components, it is a kind of the world's most advanced vertical, single stage, centrifugal, whole enclosed canned motor pump, has the unique way of support, no shaft seal without leakage, moment of inertia, high reliability maintenance is simple, the overall occupancy space is little, hydraulic model outstanding, auxiliary system simplified etc., power up to 5500 kw, sixty years operation without maintenance.

       For smoothly receiving first one main pump, the company three field project management agency (SPMO) carefully review the programs, the thorough investigation details, organization field survey, give priority to pump well receiving and storage ready, and at the same time, cooperative transport unit, for all involved personnel safety technical guidance, and ensure that the main pump discharging work successfully completed.
