[Hainan Changjiang Multi-purpose Small Modular Reactor Technology Demonstration Project Approved]

On June 3, China Nuclear Power Co., Ltd. issued an announcement. The announcement pointed out that China Nuclear Power recently received the National Development and Reform Commission document "Approval of the National Development and Reform Commission on the Approval of the Hainan Changjiang Multi-purpose Small Modular Reactor Technology Demonstration Project" (NDRC Energy [2021] No. 733). Its Hainan Changjiang multi-purpose small modular reactor technology demonstration project (small reactor demonstration project) has been approved by the State Council.

The Hainan Changjiang Multi-purpose Small Modular Reactor Technology Demonstration Project is owned by CNNC Hainan Nuclear Power Co., Ltd., a wholly-owned subsidiary of the company, and adopts the "Linglong No. 1" small reactor nuclear power unit technology of the company’s controlling shareholder, China National Nuclear Corporation. The unit capacity is 125MW.

The small reactor demonstration project is of great significance to promote the safe development and independent innovation of nuclear power, and to provide green energy guarantee for the construction of the Hainan Free Trade Port and the ecological civilization demonstration zone. China Nuclear Power will adhere to the principle of quality before progress, safety first, quality first, strengthen project construction management, thoroughly implement the new development concept, integrate the green development concept into the whole process of nuclear power construction and management, and better serve the improvement of the ecological environment, local economic and social development, to ensure high-quality completion of the Hainan Changjiang multi-purpose small modular reactor technology demonstration project.

Hot Functional Testing of HTR-PM Reactors Starts - World-Energy
05 Jan 2021 by World Nuclear News

Tests that simulate the temperatures and pressures which the reactor systems will be subjected to during normal operation have started at the demonstration high-temperature gas-cooled reactor plant (HTR-PM) at Shidaowan, in China's Shandong province. The twin-unit HTR-PM is scheduled to start operations later this year.

Cold functional tests - which aim to verify the reactor's primary loop system and equipment as well as the strength and tightness of its auxiliary pipelines under pressure higher than the design pressure - were completed at the two reactors on 19 October and 3 November, respectively. Cold functional tests at other types of reactors use water, while those at the HTR-PM reactor used compressed air and a small amount of helium as the test medium.

Hot functional tests involve increasing the temperature of the reactor coolant system and carrying out comprehensive tests to ensure that coolant circuits and safety systems are operating as they should. Carried out before the loading of nuclear fuel, such testing simulates the thermal working conditions of the power plant and verifies that nuclear island and conventional equipment and systems meet design requirements.

Hot tests at the HTR-PM are expected to take about two months to complete and are divided into three stages: vacuum dehumidification; heating and dehumidification; and hot functional testing. The main items of the hot functional test include the thermal performance testing of: the main helium fan; the fuel handling system; the control rod and its driving mechanism; the helium purification system; and, the absorption ball system. The main purpose is to dehumidify the ceramic components and pre-installed graphite balls in the reactor under helium atmosphere. At the same time, in accordance with the actual operating parameters of the plant, the consistency of the various functions and performance indicators of the system with the design regulations was verified.

The vacuum dehumidification stage of the hot tests was started at the two HTR-PM reactors on 25 November and 14 December, respectively. The heating and dehumidification stage of the tests was completed at both reactors on 30 December. The reactor loop temperature was stabilised at 250°C and the pressure was maintained at 7MPa in both reactors. The final stage of the hot tests - the hot functional test - of both reactors together, rather than individually, will now be carried out.

China National Nuclear Corp (CNNC) said the hot tests have "laid a solid foundation for fully verifying the system's function, reliability, subsequent fuel loading, grid-connected power generation and other engineering goals."

Construction of the demonstration HTR-PM plant - which features two small reactors that will drive a single 210 MWe turbine - began in December 2012. Helium gas will be used as the primary circuit coolant. China Huaneng is the lead organisation in the consortium to build the demonstration units (with a 47.5% stake), together with CNNC subsidiary China Nuclear Engineering Corporation (CNEC) (32.5%) and Tsinghua University's Institute of Nuclear and New Energy Technology (20%), which is the research and development leader. Chinergy, a joint venture of Tsinghua and CNEC, is the main contractor for the nuclear island.

A further 18 such HTR-PM units are proposed for the Shidaowan site. Beyond HTR-PM, China proposes a scaled-up version called HTR-PM600, which sees one large turbine rated at 650 MWe driven by some six HTR-PM reactor units. Feasibility studies on HTR-PM600 deployment are under way for Sanmen, Zhejiang province; Ruijin, Jiangxi province; Xiapu and Wan'an, in Fujian province; and Bai'an, Guangdong province.

Just now, the world's first high-temperature gas-cooled reactor (pebble-bed modular) demonstration project began fuel loading. The high-temperature gas-cooled reactor uses spherical nuclear fuel elements. Spherical fuel elements are the most important basis for the inherent safety of high-temperature gas-cooled reactors. It is a key core technology that can't be purchase and manufactured by China National Nuclear Corporation North Nuclear Fuel Element Co., Ltd.
