Doosan wins second Chinese nuclear control systems contract
CHINA
SOUTH Korea’s Doosan Heavy Industries & Construction has won a contract from China Techenergy Company (CTEC) to supply an Industrial Anti-seismic Protection System (IAPS) for two reactors at the Russian-designed Tianwan Nuclear Power Plant (NPP) in China, World Nuclear News reported.
The move follows CTEC’s award earlier this year of a similar contract to Doosan for IAPS systems for units 3 and 4 at the Xudabao NPP in Liaoning province.
The IAPS technology would automatically shut down the reactor if the earthquake sensor reaches or exceeds the set value during operation of the nuclear power plant. The IAPS is part of a reactor’s instrumentation and control system.
Doosan is to supply the IAPS systems, based on CTEC’s FirmSys digital I&C platform, to Tianwan units 7 and 8 by 2024.
In June 2018, Russia and China signed four agreements, including for the construction of two VVER-1200 reactors as units 7 and 8 of the Tianwan plant.
In addition, two further VVER-1200 units are to be constructed at the new Xudabao (also known as Xudapu) site. All four units are expected to be commissioned in 2027-2028.

The ceremony included the pouring of first concrete for Tianwan 7. First concrete for Xuda- bao 3 was poured on 28 July.
In March, CTEC awarded Doosan a contract for the IAPS systems for Xudabao units 3 and 4, marking its first contract for nuclear power instrumentation and control (I&C) in the Chi- nese nuclear market. Under that contract, the company will design, manufacture, test and install the systems by 2024.
In January 2018, Doosan, which supplied IAPS systems to all 28 of South Korea’s power reactors, signed a Memorandum of Understand- ing with CTEC to promote cooperation, which contributed to the award of these IAPS contracts.
“We were able to establish a trustful relation- ship with our customer with proven technology based on abundant experiences and track record in the domestic nuclear market,” said Kiyong Na, CEO of Doosan Heavy’s Nuclear Business Group.
“We will commit to successfully carry out Xudapu units 3 and 4 and Tianwan units 7 and 8 projects with CTEC as the general contractor, and at the same time continue to pursue new opportunities to participate in overseas nuclear powerplantmarkets.”
