REACTOR HALTS AFTER PUMP MALFUNCTION|核三廠一號機跳機 台電:無核安疑慮

On Jan.24, the first reactor of the No. 3 Nuclear Power Plant suffered a malfunction. One of the reactor's cooling water pumps tripped, causing the cooled water inside the machine to decrease, triggering the reactor to stop operating automatically. Taipower said that there is no threat of radiation, and they will identify the cause of the incident as soon as possible. In the morning of Jan. 24, at 6:25 am, one of the two reactors at the No. 3 Nuclear Power Plant stopped working. White smoke was even seen by nearby residents. According to Taipower, one of the first reactor's cooling water pumps malfunctioned, triggering the reactor to automatically stop operating. It also said that the white smoke was just water vapor, generated naturally when the reactor stops. Although there is no threat of radiation, Taipower said that the reactor malfunction affects the stability of power supply. ==LIN TE-FU Taipower Spokesperson== Power supply is affected, around 3 percent or more. (Will it be repaired soon?) We are now investigating into the incident, and we have clues to it. The No. 3 Nuclear Power Plant is the only pressurized water reactor plant in Taiwan. When cooled water is sent to the reactor, hot water is generated and sent to the turbine to produce water vapor. The water vapor then pushes the generator, creating power. The cooled hot water is transferred back to the cooling water pump and sent back to the reactor for re-use. In this incident, one of the cooling water pumps went wrong, resulting in a low level of water in the cycle, leaving the reactor unable to work. However, the Atomic Energy Council said that detailed cause of the incident requires further investigation. ==LI CHI-SSU Deputy Director of the Department of Nuclear Regulation, Atomic Energy Council== This happened once before in the 1990's, causing the reactor to suddenly stop. There was a problem with the electricity supply. We are still looking into this latest incident. After identifying the cause, Taipower needs to submit a report to the AEC for review to reopen the first reactor. Since the reactor accounts for 3 percent of the total power supply, the incident provoked an orange alert, meaning that the current percent operating reserve is below 6 percent. TRANSLATED BY：ARIEL HSIEH 目前核一核二廠，四部機組有三部大修停機，原本持續運轉的核三廠的兩部機組，一號機卻在凌晨6點25分跳機，有民眾還目睹有白煙冒出，對此台電表示，是反應爐其中一部冷卻水泵跳脫，機組馬上自動安全停機，沒有輻射外洩等核安疑慮，並解釋白煙是水蒸氣，停機時會出現的正常現象，但台電坦言，這次跳機會多少會影響供電穩定。 ==台電發言人 林德福== 或多或少有影響 大概將近(佔總發電量)3% 3點多% (所以會希望趕快盡快修復嗎) 我們現在努力在追查原因 有點方向 有方向 核三廠是國內唯一一座壓水式電廠，將冷卻水送進反應爐，產生熱水輸送至汽機產生水蒸氣，再推動發電機來發電，而降溫後的熱水，再由冷卻水泵，抽送到爐心繼續循環利用，這次出問題的是冷卻水泵，造成迴路中的水流流量過低，引動反應爐急停，原能會表示詳細原因還需要調查。 ==原能會核能管制處副處長 李綺思== 民國八十多年的時候 確實這個反應器的冷卻水泵 曾經有跳脫過造成反應爐急停 那時候的事情大概是因為 主要是電器方面的問題 不過這一次的事件 目前還在調查原因當中 查明原因後，台電需要提出綜合檢討報告，經原能會審查完成後，才能重啟一號機，而一號機的發電量約佔總發電量3%，跳機意外讓今天備轉容量率只剩4.63%，來到「供電警戒」的橘燈。 記者 林靜梅 陳立峰 台北報導
