Nuclear power, one of the cleanest energy resources, is the main direction of power energy development. Our company has accumulated many R&D and application experiences through continuous development. We have successfully developed many nuclear pump products, such as stage high-pressure safety injection pumps, containment spray pumps, nuclear island sump pumps, etc. Now, we are committed to the development of stage 2 and 3 pumps for nuclear power plants and primary water-supply pumps, circulation pumps, condensate pumps, vacuum pumps, magnetic pumps, etc., which are used in the normal nuclear island. Our expertise in nuclear pumps ensures the reliability and safety of nuclear power generation.
Expanding our expertise in nuclear pumps, we’re dedicated to enhancing the efficiency and safety of nuclear power generation. Our commitment extends to advanced research and development, ensuring the reliability of critical systems within nuclear power plants. Trust our proven track record for delivering high-performance solutions in the demanding nuclear industry.
Extremely High Reliability and Safety:
Safety Standards and Certifications: All nuclear-grade equipment must comply with stringent international safety standards and regulations (e.g., ASME Boiler and Pressure Vessel Code Section III for Class 1, 2, or 3 components) to ensure safe operation under extreme conditions.
Failure Mitigation: Designed to prevent operational interference or human error from escalating into problems, and typically equipped with redundancy systems to control damage and prevent the release of radioactive materials.
Tolerance for Extreme Operating Conditions:
High Temperature and Pressure: Pumps in nuclear reactor cooling systems (e.g., reactor cooling water pumps, RCP) need to operate at temperatures exceeding 300°C and extremely high pressures (approximately 150 times atmospheric pressure).
Radiation-resistant materials: Constructed using special materials such as forged martensitic stainless steel, these materials resist radiation exposure and severe mechanical loads.
Corrosion resistance: Internal components have enhanced corrosion resistance to meet the demands of long-term operation in environments with strictly controlled water chemistry conditions.
Robust mechanical design: Large diameter spindles and forged components: Robust structures, such as large-diameter spindles and forged main components, ensure maximum mechanical load-bearing capacity.
Reduced stress concentration: Design improvements, such as reducing the number of grooves on the spindle, minimize stress concentration areas, improving long-term reliability.
Easy to maintain and monitor:
Automated monitoring system: Equipped with a comprehensive monitoring and control system to detect equipment malfunctions, temperature and pressure anomalies, minimizing the risk of accidents.
Simplified structure: Certain designs (such as using internal pressure balancing bores instead of external balancing pipes) are designed to reduce the number of parts, welds, and flange connections, thereby improving reliability and simplifying maintenance.
