"Fax Agency" cited a document that the number of man-made downtime hours in the first year of the Taishan Nuclear Power Plant was the highest in the country

Unit 1 of the Guangdong Taishan Nuclear Power Plant, a Sino-French joint venture, had to stop the operation of the reactor for inspection and repair due to damage to its nuclear fuel rods at the end of July this year, and it has not restarted yet.

"Fax" quoted data from the International Atomic Energy Agency, showing that the Taishan Nuclear Power Plant Unit 1 involved in the incident had been shut down in the first year due to "human factors" after it was turned on in mid-2018. The total number of hours was 428 hours, which was nearly 10 hours. The top 36 nuclear reactors in operation in China this year.

Unit 1 of the Taishan Nuclear Power Plant is the world’s first third-generation European Pressurized Water Reactor (EPR) to be put into commercial operation. It was reported by CNN in mid-June this year that there was a nuclear safety threat. EDF, which holds a 30% stake in the nuclear power plant The company subsequently confirmed that the inert gas in the reactor of Unit 1 had increased, which was suspected to be caused by damaged fuel rods.

EDF suggested on July 22 that Taishan Nuclear Power Plant Unit 1 should be shut down for inspection. Since the shutdown of China Guangdong Nuclear Power Plant, the unit has not yet announced its reopening plan.

The "Fax Agency" checked the data of the "Operational Experience Report on Nuclear Power Plants (OPEX) of Member States" published by the International Atomic Energy Agency in the past three years. It showed that Unit 1 of the Taishan Nuclear Power Plant had unplanned shutdowns in the past.

After the unit started up in mid-2018, in the first year, it recorded multiple unplanned shutdowns due to human error, with a total of 428 hours.

Taishan Unit 1 recorded 428 hours of unplanned shutdown in the first year of startup

In the past ten years (between 2011 and 2020) there were 36 new nuclear reactors on the mainland.

According to data, there were 3 units that had unplanned shutdowns due to "human factors" within 1 year after the start-up, including Taishan Unit 1, Shandong Haiyang Unit 2, and Fujian Ningde Unit 3. The shutdown hours were 428 hours, respectively. 328 hours and 264 hours.

Unit 1 of the Taishan Nuclear Power Plant received 20 nuclear fuel improvement requirements from the National Nuclear Safety Administration in December 2017, about 4 months before the first nuclear fuel was installed.

According to the National Nuclear Safety Administration’s "Comprehensive Nuclear Safety Inspection Report for Unit 1 of Taishan Nuclear Power Plant before the First Fuel Loading", it is required to improve the responsibilities and division of labor for fuel management procedures, as well as the problems that operators have not completed training.

The unit was started up in June 2018 and was put into commercial operation at the end of the same year. A total of 12 operating incidents occurred, including 5 involving human factors and 3 triggering automatic reactor shutdowns, including accidental collision of generators and transmission protection systems The pressure of the intermediate relay and the steam generator is too high and the water level of the steam generator is too high.

Expert: Reflecting the lack of training in nuclear power plants

In its report, "Fax" quoted Lu Binglin, chairman of the Hong Kong Nuclear Society, as saying that the number of hours of unplanned shutdowns caused by human factors mainly reflects the training of nuclear power plant operators. "It is training or unfamiliar with the crew, which means training. It must be strengthened. (Training) opportunities are not enough. It means that when I first learn to use nuclear power plant simulation units, I will basically trigger automatic shutdown frequently. After getting familiar with it, it will be better. So if there are often unplanned human factors Shutdown means that the training of (operators) needs to be reviewed, or the examination of personnel needs to be strengthened."

He also pointed out that both new and old reactors will have operators who are unfamiliar with the reactor. For example, in old reactors such as Daya Bay, most of them will use an analog signal (analog) system, which is also a test of the experience of the operators. "You said the new or the old Yes, I think there will be both (unfamiliar with the reactor situation), the most important thing is to see whether the manpower training is sufficient."
