Nuclear safety equipment market took the lead

The restart of domestic new nuclear power projects has always been one of the focuses of the market. With the approach of the end of the “Twelfth Five-Year Plan”, 2015 will be the sprint period for the completion of various planning goals. A group of coastal nuclear power projects will be formally approved for construction and will become a high probability event. Under the guidance of the strategic concept of "safe development of nuclear power," the nuclear safety equipment market will take the lead.

The National Energy Work Conference 2015 held on December 25, 2014, listed “safe development of nuclear power” as the focus of energy work for the whole year of 2015, and it was one of the key players in vigorously promoting the energy supply revolution. The meeting clearly stated that “on the premise of adopting the highest international nuclear power safety standards and ensuring safety, we must start building mature nuclear power projects; break through the development of key nuclear power equipment; and select a group of nuclear power plants for protection and in-depth demonstration”.

Since the release of the nuclear safety plan in 2012, safety has been positioned as the most important principle for the development of nuclear power in the country in the future. With the successive construction of new nuclear power projects, some nuclear safety equipment designed to improve the safety level of nuclear power projects will be gradually introduced into the nuclear power plant construction sequence. The restart of nuclear power will lead to the opening of the nuclear safety equipment market.

In a series of nuclear safety equipment, especially the main pump that drives the coolant circulation in the primary circuit of a nuclear power plant? And waste heat removal system is the most important. Among them, the main pump motor and the residual heat removal pump motor are the most important part. At present, China’s nuclear power plants are mainly based on pressurized water reactors or pressurized water reactors, and their main pump motors are not domestically produced. However, the main helium fan used for helium cooling in the new generation of high-temperature gas-cooled reactors with independent intellectual property rights is equivalent to the main pump fan of the pressurized water reactor, and its drive motor is about to be domesticated.

The core component of the waste heat removal system is the waste heat removal pump. During the shutdown of the reactor, the waste heat removal pump circulates the reactor coolant between the waste heat removal system heat exchanger and the reactor pressure vessel to ensure that the power plant enters a cold shutdown state; after normal shutdown and accident shutdown, Core decay heat is generated to maintain the nuclear power plant in a safe state. Waste heat removal pump motor used as the pump drive motor, is the only identification type K1 class of motor in the pressurized water reactor nuclear power plant, the nuclear safety level is the highest level. These key equipments are expected to become the first segment of nuclear power safety equipment to benefit from the proposed safety standards for nuclear power construction.

Jiadian is the only company in China that has a supply qualification for motor for containment cores, with a market share of over 90%. The company announced on August 12, 2014 that the drive motor for the main helium fan application was independently developed by Jiadian, achieving a major breakthrough in frequency conversion, high power, high speed, and vertical motor technology in China, marking the high temperature gas cooled reactor owner. The core technology of the blower core has been solved. We believe that technological superiority enhances the company's core competitiveness. Along with the advancement of the national demonstration project for high-temperature gas-cooled reactor nuclear power plants, the company's drive motor developed in the future will become a mass production product and will have a positive impact on the company's profits.

Jiadian announced on December 22 that the company's large-scale waste heat removal pump K1 motor has been tested by the National Nuclear Safety Administration and China National Nuclear Power Engineering Corporation under the joint testimony of the LOCA in-house test. "Assembly inspection test" test and successfully passed. Jiadian is currently the only company in China that can provide waste heat pump motors. As the only domestic civil nuclear safety equipment design and manufacturing license company, after completing the LOCA test, it will become the only listed company's nuclear power safety target company.
