Introduction

R&D CENTER >>HPR 1000

Chinese Generation-III nuclear power technology with our proprietary intellectual property has become the preferred reactor technology for China’s nuclear power industry’s “going global” strategy.

HPR1000 is one of the most widely-received Generation-III nuclear power models on the market. It was developed through joint research and development by CGN and China National Nuclear Corporation(CNNC), and based on experience, breakthrough technologies, and excellent human resources accumulated through 30 years of design, construction, and operation of nuclear power plants.

Advantages

  • It enjoys full proprietary intellectual property rights.
  • It is of internationally advanced levels in terms of technological safety and has the economic advantage compared with other reactors and the former three generations of mainstream models with a domestic benchmark construction cost of less than $2,500 per kilowatt.
  • It has the competitive advantage in the industrial chain. Thanks to mature domestic equipment manufacturing systems and capacity strength, an advantage in “going global”, or reaching international markets, has been obtained through supply chain formation. It is expected that 10 to 12 new units will be constructed every year and each of them will offer over 20,000 jobs.

Features

Single Reactor Layout

  • Single reactor layout optimizes the buildings layout in nuclear island.
  • Better physical isolation avoids common mode failure of safety systems.
  • It is convenient for construction, operation and maintenance.

Double Containment

  • The large volume improves safety in case of an beyond-design accident or severe accident.
  • The annular space ventilation system is designed for double containment, minimizing the risk of releasing radioactive substances into the environment when accident occurs, and thus improving the safety of the power plant.
  • The outer shell of the containment is able to withstand the crash of large commercial airplanes.

Three Safety Trains

  • It has three physically isolated safety trains.
  • It is of 3×100% redundant safety guarantee.
  • The CDF is one order of magnitude lower than that of a two-train configuration scheme, so that it can better respond to both internal and external accidents.

Combination of Active and Passive

  • It has the Secondary Side Passive Residual Heat Removal System. When the active feed-water system fails, the residual heat of the reactor core and stored heat in all equipment tied to the reactor coolant system can be removed via steam generators.
  • It has the Passive Reactor Pit Injection System (IVR). When the severe accident like core melt-down occurs, it helps to maintain the integrity of the pressure vessel.

Technological Certifications of HPR1000

  • It is developed in accordance with China’s latest safety standard HAF102, and the requirements of the US’s Utility Requirements Documents and Europe’s European Utility Requirement (EUR). The standard combines the experience of the Fukushima nuclear accident and internationally advanced design ideas.
  • Currently, the EUR has agreed to accept its application for certification. The process is expected to be launched in 2017 and takes about three years. The CGN is preparing for the Generic Design Assessment (GDA).
