| 五、核事故應對處置主要措施 | V. Main Measures to Cope with Nuclear Accidents |
| 中國參照國際先進(jìn)標準，汲取國際成熟經(jīng)驗，結合國情和核能發(fā)展實(shí)際，制定了控制、緩解、應對核事故的工作措施。 | By referring the advanced international standards and drawing on worldwide mature experience, China has defined working measures to control, mitigate and cope with nuclear accidents commensurate with its national conditions and actual situation of nuclear energy development. |
| 實(shí)施縱深防御。設置五道防線(xiàn)，前移核應急關(guān)口，多重屏障強化核電安全，防止事故與減輕事故后果。一是保證設計、制造、建造、運行等質(zhì)量，預防偏離正常運行。二是嚴格執行運行規程，遵守運行技術(shù)規范，使機組運行在限定的安全區間以?xún)龋皶r(shí)檢測和糾正偏差，對非正常運行加以控制，防止演變?yōu)槭鹿省Ｈ侨绻钗茨芗皶r(shí)糾正，發(fā)生設計基準事故時(shí)，自動(dòng)啟用電廠(chǎng)安全系統和保護系統，組織應急運行，防止事故惡化。四是如果事故未能得到有效控制，啟動(dòng)事故處理規程，實(shí)施事故管理策略，保證安全殼不被破壞，防止放射性物質(zhì)外泄。五是在極端情況下，如果以上各道防線(xiàn)均告失效，立即進(jìn)行場(chǎng)外應急響應行動(dòng)，努力減輕事故對公眾和環(huán)境的影響。同時(shí)，設置多道實(shí)體屏障，確保層層設防，防止和控制放射性物質(zhì)釋入環(huán)境。 | Implementing the defense-in-depth concept. Five lines of defense have been set up under which the nuclear emergency preparedness threshold is moved ahead and multiple barriers are installed to strengthen nuclear safety, prevent accidents and mitigate the consequences of an accident. The five lines of defense are: First, the quality of design, manufacturing, construction and operation shall be assured to prevent deviation from normal operation; second, operation procedures and operation technical specifications shall be rigorously followed and observed to ensure that each nuclear generating unit is operated within the defined safety range, any deviations therefrom are detected and corrected in a timely manner, and any abnormal operation is controlled to prevent it from evolving into an accident; third, in case a deviation fails to be corrected in a timely manner, plant safety and protection systems shall be automatically activated upon occurrence of an accident within the design datum, and emergency operations shall be organized to prevent the situation deteriorating; fourth, in case an accident fails to be controlled effectively, accident handling procedures shall be activated with the accident management strategy enforced to ensure that the containment shall remain intact and no radioactive substances are released into the environment; and fifth, in the event of failure of the above-mentioned lines of defense, off-site emergency actions shall be immediately activated in an effort to minimize any impact from the accident on the public or the environment. Meanwhile, multiple physical barriers shall be set up to ensure that multiple lines of defense are in place to prevent and control release of radioactive substances into the environment. |
| 實(shí)行分級響應。參照國際原子能機構核事故事件分級表，根據核事故性質(zhì)、嚴重程度及輻射后果影響范圍，確定核事故級別。核應急狀態(tài)分為應急待命、廠(chǎng)房應急、場(chǎng)區應急、場(chǎng)外應急，分別對應Ⅳ級響應、Ⅲ級響應、Ⅱ級響應、Ⅰ級響應。前三級響應，主要針對場(chǎng)區范圍內的應急需要組織實(shí)施。當出現或可能出現向環(huán)境釋放大量放射性物質(zhì)，事故后果超越場(chǎng)區邊界并可能?chē)乐匚＜肮娊】岛铜h(huán)境安全時(shí)，進(jìn)入場(chǎng)外應急，啟動(dòng)Ⅰ級響應。 | Exercising a tiered response scheme. The level of a nuclear accident shall be determined in accordance with the nature and seriousness of the accident and scope of effect from radiation, based on the International Nuclear and Radiological Event Scale (INES) guidelines of the International Atomic Energy Agency. The nuclear emergency preparedness condition is divided into Emergency Standby, Building Emergency, On-Site Emergency and Off-Site Emergency, which respectively correspond to Level IV response, Level III response, Level II response and Level I response. The first three levels of response mainly focus on the organization and implementation of emergency actions within the site. Off-Site Emergency shall be announced with its corresponding Level I response activated upon occurrence of release or possible release of a large quantity of radioactive substances into the environment in which accident consequences have crossed boundaries of the site, with the possibility of seriously jeopardizing public health and environmental safety. |
| 部署響應行動(dòng)。核事故發(fā)生后，各級核應急組織根據事故性質(zhì)和嚴重程度，實(shí)施以下全部或部分響應行動(dòng)。 | Deploying actions of response. Every level of nuclear emergency organization shall implement the following response actions in whole or in part depending upon the nature and seriousness of the accident: |
