OREANDA-NEWS. February 16, 2011. The first set of self-designed and localized-manufactured reactor vessel internals for 1,000 MW nuclear power station in China had passed the inspection test and made debut in Shanghai No. 1 Machine Tool Works Co., Ltd of Shanghai Electric Heavy Industry Group, reported the press-centre of Shanghai Electric.

It is also the first set of CPR1000 nuclear power reactor vessel internals manufactured in China, which demonstrated the remarkable achievement made by Shanghai Electric with its utmost endeavour in pursuing technology innovation on products and enhancing its core competitiveness. The successful production of the reactor vessel internals marked the localization of key components for nuclear power reactor has achieved international standards.

This set of nuclear island equipment, manufactured by Shanghai No. 1 Machine Tool Works Co., Ltd., was tailor-made for the facilities of Hongyanhe No. 1 Nuclear power unit. It was in a cylindrical shape (so-called “big cylinder”), with 9 meters in height and 138 tons in weight. More than 12,000 precision component parts were welded precisely together in this bulky structure and then resulted in an enormous “state of the art” product. It is also considered to be a cutting-edge product which recorded the Company’s break-through on technology innovation and exploration in line with the central government’s strategy.
