中文摘要 | 本文係對清華水池式反應器(THOR)歷經37年累積44,456,058千瓦時之總能量運轉 後,其核心燃料格架組件、控制板與中子通率偵檢器等相關設備的輻射劑量詳加度量,供制 定 THOR 核心燃料格架組件更新作業的適當輻射防護措施,確保工作人員的輻射防護安全。 原有的 THOR 核心燃料格架組件經過約兩個月冷卻後其輻射劑量度量分析結果顯示,輻射劑 量主要來自核心燃料格架與支柱鎖合之不�袗�材質螺絲所產生的鈷 60 放射性核種,所有參 與工作人員所接受的輻射劑量,均低於各人員劑量計對輻射劑量反應的最低劑量限值。 |
英文摘要 | After 37 years of operation with a total thermal output of 44,456,058 kW hr, the radiation dosimetry on the reactor core, fuel rack, fission detector and control blades of the Tsing Hua Open Pool Reactor was measured after 2 months of shutdown. The only detectable radioisotope from the fuel rack and its supports is �h Co. These �h Co sources located at the stainless steel bolts used to tight supports and fuel rack. A strict safety measure of the radiation protection during the replacement of fuel rack was carried out. The maximum total dose received by the maintenance people is not detectable. |
