中国称台山核电站周围的辐射水平在报告泄漏后正常

香港 China said Tuesday that radiation levels around the Taishan Nuclear Power Plant are normal, 以下 CNN’s exclusive report the United States government was assessing a reported leak at the facility.

There is no abnormality in the radiation environment around the nuclear power plant. Its safety is guaranteed,” foreign ministry spokesperson Zhao Lijian told a news briefing in Beijing.
在星期一, CNN reported that the French company which helps operate the nuclear plant in southern Guangdong province had warned Washington of animminent radiological threat.
    The warning included an accusation the Chinese safety authority was raising the acceptable limits for radiation detection outside the plant in order to avoid having to shut it down, according to a letter from French firm Framatome to the US Department of Energy, CNN获得.
      Responding to the report on Tuesday, Zhao said the Taishan plant was fully compliant with all technical requirements.
        China attaches great importance to nuclear safety and has established a nuclear safety supervision system that is in line with international standards and national conditions,” 他说. “China’s nuclear power plants as of now have maintained a good operating record. There have been no incidents affecting the environment and public health.
        然而, Zhao declined to answer follow-up questions regarding Framatome’s language in its warning to US officials, 特别, its use of the term “迫在眉睫的放射性威胁,” and the suggestion that Chinese authorities had raised acceptable limits of radiation for the plant and its surrounding area.
          在星期三, China’s National Nuclear Safety Administration (NNSA) denied raising the acceptable limits of radiation outside the plant to avoid its shutdown.
          代替, the regulator said itreviewed and approved the relevant limits of specific radioactivity of inert gases in the reactor coolant at the Taishan Nuclear Power Plant.
          These limits are used for operational management and have nothing to do with radiation levels outside the nuclear power plant,” the administration said in a statement on its official social media account.
          Echoing earlier statements by the plant’s French co-owner Electricite de France (法国电力公司), which is the majority owner of Framatome, the NNSA acknowledged an increased level of radioactivity in the primary circuit in one of the two reactors due to damaged fuel rods.
          The increase in the level of radioactivity in the primary circuit is completely different from a radiological leakage accident,” 作为 “physical barriers are safe,” 它说, adding the levelis still within the range of allowable stable operation,” 和 “operational safety of the nuclear power plant is guaranteed.
          The agency said only five of the reactor’s more than 60,000 fuel rods have been affected, reiterating there is no risk of “辐射泄漏到环境中。”
          先前, the plant’s owners have maintained that environmental readings for both the facility and its surrounding areas werenormal.In a statement Sunday, they said the two nuclear reactors in Taishan are both operational, adding that Unit 2 had recently completed an “大修” 和 “successfully connected to the grid on June 10, 2021.” It did not define why or how the plant was overhauled.
          Despite the alarming notification from Framatome, the Biden administration believes the facility is not yet at acrisis level,” 一位消息人士告诉CNN.
          EDF 持有 30% stake in the power plant’s owner and operator, TNPJVC — 与国有的中国广核集团的合资企业.
          China General Nuclear Power Group and three of its affiliates were added to a US entity list 在八月 2019, cutting the Chinese company’s access to US technology.
          Framatome had reached out to the US in order to obtain a waiver that would allow them to share American technical assistance in order to resolve the issue at the Chinese plant.
          US officials have been monitoring the situation and believe it does not currently pose a severe safety threat to workers at the plant or Chinese public. But the concern was significant enough that the National Security Council held multiple meetings last week.
          The Biden administration has discussed the situation with the French government and their own experts at the Department of Energy, 消息人士说. The US has also been in contact with the Chinese government, US officials said, though the extent of that contact is unclear.
          In a statement to CNN on Friday, Framatome acknowledged itis supporting resolution of a performance issue with the Taishan Nuclear Power Plant in Guangdong Province, China.
          According to the data available, the plant is operating within the safety parameters. Our team is working with relevant experts to assess the situation and propose solutions to address any potential issue,” 声明添加.
          在星期一, French utility company EDF said in a statement it has been informed of an increased concentration ofnoble gases in the primary circuitof reactor number 1 of the Taishan plant.
          EDF saidthe presence of certain noble gases in the primary circuit is a known phenomenon, studied and provided for in the reactor operating procedures,” but did not elaborate on gas levels.
          Later on Monday, a spokesperson for EDF said the increased levels of radiation were caused by adegradation of the housing of the fuel rods.
          The spokesperson affirmed that the levels of radioactivity observed at the plant were below the threshold stipulated by the Chinese authorities, adding the affected housings are the first of three containment barriers between the rods and the atmosphere.
            The spokesperson noted the risk of a potential leakage in the rod housing was first discussed following a planned refueling outage in October 2020 after initial measurements led to suspicions of alack of tightnessin the housings.
            然而, the spokesperson stressed that without a full analysis, it is too early to confirm whether a complete shutdown of the reactor is needed, adding that EDF currently has no information regarding the origin of the rod housing degradation.
