Hualong One simulator ready for operator training

Monday, 17 September 2018

Simulators are a vital piece of equipment for training plant operators, both at the start of their careers and for their continuing training.

CNNC said the new simulator passed the acceptance test and was officially delivered 115 days in advance of schedule. Experts concluded that all the indicators of the Hualong One full-scope simulator meet the relevant functional and performance requirements, it added, and the simulator is now ready to be used to train reactor operators.

Developed by CNNC subsidiary Wuhan Nuclear Power Operation Technology Company Limited, the simulator uses a variety of international advanced technologies to simulate the operation of a nuclear power plant, both under normal and emergency conditions. It uses the latest platform and software to which CNNC Wuhan has complete independent intellectual property rights.

The simulator exactly replicates the control room of Fuqing unit 5 - the first of two demonstration Hualong One units at the site in China's Fujian province.

Installation of the control room at Fuqing 5 was completed last month. The final display panel of the control room was installed on 4 August, China Nuclear Industry 23 Construction Company announced on 7 August. The company said this was six days ahead of schedule and marked the reactor's transition from the installation phase to the system commissioning phase.

In November 2014, CNNC announced that the fifth and sixth units at Fuqing will use the domestically-developed Hualong One pressurised water reactor design, marking its first deployment. It had previously expected to use the ACP1000 design for those units, but plans were revised in line with a re-organisation of the Chinese nuclear industry. China's State Council gave final approval for construction of Fuqing units 5 and 6 in April 2015.

The pouring of first concrete for Fuqing 5 began in May that year, marking the official start of construction of the unit. Construction of unit 6 began in December the same year. The dome of unit 5 was installed on the containment building in May last year and the reactor pressure vessel was installed in January this year.

Fuqing 5 and 6 are scheduled to be completed in 2019 and 2020, respectively.

Construction of two Hualong One (HPR1000) units is also under way at China General Nuclear's Fangchenggang plant in the Guangxi Autonomous Region. Those units are also expected to start up in 2019 and 2020. Two HPR1000 units are under construction at Pakistan's Karachi nuclear power plant. Construction began on Karachi unit 2 in 2015 and unit 3 in 2016; the units are planned to enter commercial operation in 2021 and 2022. The HPR1000 has also been proposed for construction at Bradwell in the UK, where it is undergoing Generic Design Assessment.
