Daya Bay nuclear plant says incident was no radioactive leak

The Guangdong Nuclear Power Station in Daya Bay suffered a mild radioactive leakage in late November during a maintenance check, Ming Pao Daily reports, citing a Weibo account on nuclear power in mainland China.

The leakage was sealed three days later using molding equipment but the vicinity is contaminated by radioactive material, according to the report. 

Sources said the leak occurred in the pulsation damper of the main pump.

Engineers took a few hours to come up with a sealing solution but the molding equipment took two days to make.

The equipment was assembled and installed on site on the third day of the leak. The plant did not make any disclosure about the incident.

Hong Kong Nuclear Investment Co. Ltd. (HKNIC), operator of the plant several kilometers from Hong Kong, confirmed the incident on Saturday afternoon but said there was no radioactive leaking, news website hk01.com reports.

The company said the plant’s operation is normal.

HKNIC said there is no radioactivity in the pump pulsation damper, so no harm has been done to employees, the power plant and the environment.

According to thestandnews.com, a major maintenance exercise was carried out at the plant between late October and early December.

Engineer Albert Lai said it is worrying that the Daya Bay plant failed to make a timely disclosure.

Lai and several legislators, including Tanya Chan, have written to the Security Bureau to look into the matter.

Chan, who heads the Legislative Council’s panel on environmental affairs, said she heard from Secretary for Security Lai Tung-kwok that it was not a radioactive leakage.

Chan said she will keep tabs on the safety measures taken by the nuclear plant.
