China Nuclear Power Technology Research Institute Reduces Computing Time for Each Refueling Program by 100% and Improves System Capacity by 20x

China Nuclear Power Technology Research Institute (CNPRI) is a fully-owned subsidiary of China Guangdong Nuclear Power Group (CGN) and its most important technical center. CNPRI provides innovative nuclear power technology, research and development, and services to drive nuclear power development in China.

CGN was established in September 1994 with a registered capital of US$1.6 billion. By September 2012 its total assets stood at US$43 billion, and the installed capacity of its operational nuclear power plants generated 6,120 megawatts of electricity.

A word from China Nuclear Power Technology Research Institute (CNPRI)

  • “We chose Oracle’s SPARC Enterprise M9000 server, running Oracle Solaris, for its extremely high performance in scientific-computing to ensure a smooth and on-schedule delivery of our reactor refueling programs. We have reduced the complex computing tasks for each program by 100%, improved our system capacity by 20x, and increased the number of concurrent computing programs for engineering design and refueling from 20 to more than 400.” — Sun Jiliang, Director, Reactor Engineering Design and Safety Research Center, China Nuclear Power Technology Research Institute.

  • Deploy a highly performing server for scientific computing and operational stability to satisfy the complex tracking and simulation requirements of the reactor refueling program
  • Guarantee smooth, on-schedule implementation of refueling programs
  • Ensure the safe and full-power operation of nuclear power units while improving fuel economy
  • Provide the mainframe computer data center functionality required to support the complex construction of nuclear power projects
  • Deliver a highly scalable system that can satisfy the rapid development of additional reactor engineering designs and fuel management operations

Oracle Product and Services

  • Reduced computing time by 100% for the complex tracking and simulation required in reactor engineering design and operation of each refueling program
  • Improved system computing capacity by 20x by increasing the number of concurrent computing programs from 20 to more than 400
  • Ensured the safe and on-schedule implementation of reactor refueling programs by eliminating server bottlenecks caused by the huge computational volumes needed to optimize multichannel refueling
  • Improved fuel utilization economy by consuming less energy due to the reduced computing time for each reactor refueling program
  • Improved the average response speed for CPU computing and system throughput to ensure optimal fuel management across multiple locations, reactors, and projects in different provinces
  • Established a highly scalable, reliable, and sustainable server system by using Oracle Solaris’s predictive self-healing and live-upgrade functionalities and assisted in the long-term deployment of refueling programs and nuclear power projects

Why Oracle

Reactor refueling is an extremely important component of nuclear power operation. It is vital to replace the fuel consumed in a reactor’s daily operation to ensure the safety and economy of reactor operation. In addition, the refueling process is highly complex, and CNPRI’s extremely demanding server selection requirements were based on scientific computing performance and operational stability.

“Following in-depth evaluation and comparison of available servers, we selected Oracle’s SPARC Enterprise M9000 server on Oracle Solaris, as it has the characteristics of a mainframe computer and as many as 64 processors and 256 cores, delivering an extremely high level of scientific computing performance. The server will play a very powerful role in propelling the deployment of refueling and fuel management programs to support China’s commitment to supplying safe, clean nuclear energy,” said Sun Jiliang, director, Reactor Engineering Design and Safety Research Center, China Nuclear Power Technology Research Institute.

Implementation Process

CNPRI signed the purchase contract for the SPARC Enterprise M9000 server in January 2011. It received the equipment and conducted testing in March, and then completed data migration in April. The server was operational in May 2011.

The server undertakes the computing tasks for the 18-month fueling programs of Ningde Nuclear Power Station and the Lingao Nuclear Power Station. It also undertakes the computing tasks for daily refueling design projects, major scientific research projects, and several nuclear power projects in Hongyanhe, Fangchenggang, Lufeng, and Xianning.

Partner

Oracle partner Beijing Seadata Technology Ltd. (Seadata) undertook the scheme architecture design, survey, and transformation of the machine-room environment, core data storage migration, and operational support service, while providing 24-hour professional IT service.

“We selected Seadata as our support service provider for Oracle’s SPARC Enterprise M9000 server, as it has had many successful cases in the energy industry, including State Grid and China Southern Power Grid. Seadata is very customer focused, and it provides valuable, ongoing IT support,” said Sun.
