US media reported that there may be a leak at the Taishan nuclear power plant. Framatome, the French nuclear reactor company responsible for the operation, said the concentration of inert gas has increased.

The Security Bureau stated that the National Nuclear Safety Administration determined that there was no radioactive leak to the environment.

The chairman of the Hong Kong Institute of Nuclear Research, Lu Binglin, said in Hong Kong and Taiwan this morning that he believes that the fuel rods are leaking, but the nuclear power plant has multiple protections. In addition, Taishan is more than 100 kilometers away from Hong Kong, which is believed to have no impact on Hong Kong.

Liang Rongwu, a member of the Nuclear Safety Advisory Committee of the Guangdong Nuclear Power Plant, also pointed out that the radiation dose contained in the noble gas is not high, and it has been diluted when it is blown into Hong Kong.

Lu Binglin estimated that the incident was related to fuel rod leakage. However, the nuclear power plant was constructed with multiple barriers. The fuel rods were completely sealed, with a high-pressure cylinder outside, and a pressure cooker at the outside. In addition, the gas will be filtered out of the primary circuit. Emissions, so there will be no safety impact on the environment and Hong Kong.

Taishan Nuclear Power Plant is the world's first European pressurized water reactor

He believes that Taishan Nuclear Power Plant is the world's first European pressurized water reactor (epr), with the world's largest output rate of 1.75 million kilowatts, or the fuel rods are subject to more pressure, but it is not ruled out that the quality of the manufacturing process is not good, which leads to damage. .

The current incident is still within the controllable range. The nuclear power plant can be replaced with new fuel rods during the next major maintenance. The damaged fuel rods are placed in the storage pool to reduce the temperature and radiation before treatment.

Liang Rongwu also said: "It is necessary to find out that inert gas will be emitted normally, and it is not dangerous if it is emitted." The gas mentioned in the report can contain not high radiation doses. "Don't stay in the lungs, you can breathe. When you go out, of course you will "shine your lungs" if you take a breath."

He emphasized that the Taishan Nuclear Power Plant is far away from Hong Kong, and the inert gas will be diluted in the air, and when it is blown into Hong Kong, it can already be one-tenth of a ten thousandth of the source concentration.
