The EDG for nuclear power plant requires high-level in its quality and stability because electric power has to be immediately supplied when the nuclear power plant is stopped due to emergency accident. This solution requires such sophisticated engineering capability to design complicated logic that HYUNDAI is the very company accommodating the needs with massive experiences
Emergency diesel generators are started when the NPP unit is disconnected from the grid. mergency diesel generators safeguard the power supply to vital consumers such as the reactor cooling system so that a controlled reactor shutdown can be guaranteed.
HYUNDAI has been supplying emergency diesel generators(EDGs) for nuclear power plant for more than 30 years. With EDG systems supplied to 6 nuclear power plants, we have not only gained a wealth of experience and expertise, but also gained reputation for products that deliver outstanding reliability and performance.
Since every project has different requirement, HYUNDAI has developed a major NPP-based engineering with specialists capable of handling every aspects of project-specific NPP requirements and matching any customer's complicated needs.
All EDG projects are organized and implemented in line with NPP-related quality standards such as KEPIC QAP and ASME NQA-1. Our EDGs are safety-classified to meet the strictest regulations in the nuclear power industry, with qualifications in line with IEEE 387.
Hyundai’s HiMSEN engine has entered the Indian nuclear power plant market. The emergency generator will consist of 10 units of the 6.3MW medium sized HiMSEN Engine and be supplied to Nuclear Power Plant in Tamil Nadu, southern India by 2022. Emergency generators for nuclear power plants help reactors operate stably by supplying electric power to water pumps when nuclear power plants stop in an emergency situation. In order to prevent serious accidents such as a meltdown at nuclear power plants, emergency power must be supplied with fast time and safety operation. Hyundai Heavy Industries has received orders for a total of 47 emergency generators for domestic and overseas nuclear power plants, including those in the UAE, the United Kingdom and Pakistan, since taking the first order for Kori Nuclear Power Plant in Korea.
On July 3rd, HHI-EMD received an order from Wuxi Division of No. 703 Reserch Institute of CSIC for 5 sets of Emergency Diesel Generator (EDG) for nuclear power plant in Pakistan. The output of EDG is 8.3MW each and Hyundai HiMSEN 20H32/40V engine is applied for this EDG.
HHI has been supplying emergency diesel generators for nuclear power plants for more than 10 years. With EDG systems supplied to over 7 nuclear power plants in 5 countries worldwide, we have not only gained a wealth of experience and expertise, but also a leading market position. HHI provide products that deliver outstanding reliability and performance.
On November 2011, HYUNDAI-EMBU received an order to supply total nine(9) sets of Emergency Diesel Generators and AC Diesel Generator(Engine model : 20H32/40V) from Korea Electric Power Corporation(KEPCO).
The EDG for nuclear power plant requires high-level in its quality and stability because electric power has to be immediately supplied when the nuclear power plant is stopped due to emergency accident.
