SNPTC Completes Concept Design for 1,400-Megawatt, Large-Scale Nuclear Power Unit

---

Researched by Industrial Info Resources (Sugar Land, Texas)--Shanghai Nuclear Engineering Research and Design Institute (SNERDI) (Shanghai), a subsidiary of the State Nuclear Power Technology Corporation (SNPTC) (Beijing), has completed conceptual design for research and development (R&D) on a 1,400-megawatt (MW), large-scale, pressurized water reactor-based, CAP1400 nuclear power unit. The related R&D results passed the examination of an expert panel recently organized by the SNPTC. Preliminary engineering for the project kicked off in July 2010. The engineering of the CAP1400 unit has entered the implementation stage, according to an announcement made by the SNPTC on July 8, 2010.

CAP1400 is an R&D program aimed at building large-scale, pressurized water reactor-based, demonstrative nuclear power stations in China based on the import, dissipation, absorption and renovation of Westinghouse's AP1000 technology, which is an advanced, third-generation nuclear power technology. CAP1400 is adopted with the engineering concept of passive technology. Due to the adoption of passive technology, CAP1400 is furnished with a complete set of measures for the prevention and mitigation of serious safety accidents. In case of such an accident, the operator does not need to perform any manual operation within 72 hours; for a period of more than 72 hours, only some external assistance is required, which greatly reduces the possibility of mistakes.

In regard to engineering, CAP1400 has superior technical design. Safety evaluations identify any weakness. The adoption of advanced digital control systems, advanced control rooms, proven standardized parts, and modularized design and engineering could shorten the manufacturing cycle and reduce construction costs. Major materials and equipment in CAP1400 will be localized in China, and will satisfy progress demands specified in the middle- and long-term development plan for nuclear power.

Successful implementation of CAP1400 will promote the swift and independent development of the nuclear power industry in China; improve China's capabilities in design, R&D, manufacture and management of its nuclear power industry; and boost the strategic development of clean energy with low-carbon emission.
