| 五、核事故應對處置主要措施 | V. Main Measures to Cope with Nuclear Accidents |
| 中國參照國際先進標準，汲取國際成熟經驗，結合國情和核能發展實際，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. |
| 實施縱深防御。設置五道防線，前移核應急關口，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，遵守運行技術規范，使機組運行在限定的安全區間以內，及時檢測和糾正偏差，對非正常運行加以控制，防止演變為事故。三是如果偏差未能及時糾正，發生設計基準事故時，自動啟用電廠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，啟動事故處理規程，實施事故管理策略，保證安全殼不被破壞，防止放射性物質外泄。五是在極端情況下，如果以上各道防線均告失效，立即進行場外應急響應行動，努力減輕事故對公眾和環境的影響。同時，設置多道實體屏障，確保層層設防，防止和控制放射性物質釋入環境。 | 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、嚴重程度及輻射后果影響范圍，確定核事故級別。核應急狀態分為應急待命、廠房應急、場區應急、場外應急，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，主要針對場區范圍內的應急需要組織實施。當出現或可能出現向環境釋放大量放射性物質，事故后果超越場區邊界并可能嚴重危及公眾健康和環境安全時，進入場外應急，啟動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。核事故發生后，各級核應急組織根據事故性質和嚴重程度，實施以下全部或部分響應行動。 | 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: |
| ——迅速緩解控制事故。立即組織專業力量、裝備和物資等開展工程搶險，緩解并控制事故，努力使核設施恢復到安全狀態，防止或減少放射性物質向環境釋放。 | -- Mitigating and controlling the accident in a timely manner. A professional force, equipment and supplies shall be thrown into immediate engineering emergency measures to mitigate and control any accident in an attempt to bring the relevant nuclear installation back to a safe condition while preventing or minimizing the release of radioactive substances into the environment. |
| ——開展輻射監測和后果評價。在事故現場和受影響地區開展放射性監測以及人員受照劑量監測等。實時開展氣象、水文、地質、地震等觀（監）測預報。開展事故工況診斷和釋放源項分析，研判事故發展趨勢，評價輻射后果，判定受影響區域范圍。 | -- Conducting radiation monitoring and consequence assessment. Radiation monitoring shall be conducted at the site of the accident and areas affected and doses possibly absorbed by personnel shall be measured. Observation/surveillance and forecast on meteorological, hydrological, geological and seismic impacts shall be provided on a real-time basis. The accident conditions shall be diagnosed and substances released shall be analyzed to determine the accident evolution trend, evaluate radiation consequences and define the areas affected. |
| ——組織人員實施應急防護行動。當事故已經或可能導致碘放射性同位素釋放，由專業組織及時安排一定區域內公眾服用穩定碘，以減少甲狀腺的受照劑量。適時組織受輻射影響地區人員采取隱蔽、撤離、臨時避遷或永久遷出等應急防護措施，避免或減少受到輻射損傷。及時開展心理援助，撫慰社會公眾情緒，減輕社會恐慌。 | -- Organizing personnel to implement emergency protection actions. If radioactive isotope of iodine has already been released or may be released arising from an accident, a professional team shall organize the public within a given area to take stable iodine pills to minimize radiation exposure to the thyroid gland. The people in the affected area shall be duly organized to take emergency protection measures deemed necessary, including hiding, evacuating, seeking temporary shelter or permanently moving out in order to prevent or minimize injuries from radiation exposure. Psychological assistance shall be provided in a timely manner to minimize social anxiety and panic. |
| ——實施去污洗消和醫療救治。由專業人員去除或降低人員、設備、場所、環境等放射性污染。組織核應急醫學救援力量實施醫學診斷、分類，開展醫療救治，包括現場緊急救治、地方醫院救治和后方專業救治等。 | -- Arranging decontamination and medical treatment. Professionals shall be dispatched to remove or minimize radioactive pollution affecting people, equipment, premises and the environment. A nuclear emergency preparedness medical rescue force shall be organized to perform medical diagnoses, case identification and medical treatment, including on-site first-aid treatment, local hospital treatment and backup professional treatment. |
| ——控制出入通道和口岸。根據受事故影響區域具體情況，劃定警戒區，設定出入通道，嚴格控制各類人員、車輛、設備和物資出入。對出入境人員、交通工具、集裝箱、貨物、行李物品、郵包快件等實施放射性污染檢測與控制。 | -- Controlling access passages and ports. Zones shall be demarcated according to the areas affected and strict control shall be enforced over the passage of people, vehicles, equipment and supplies in and out of the designated passages.
