注意改進事項:
龍門電廠裝設之防火門許多不具耐火時效標籤且其防火時效未確認與防火屏障同等級,不符BTP CMEB 9.5-1 C.5.a(5)、BTP CMEB 9.5-1 B.4之規定,請檢討改正。
注意改進內容:
一、BTP CMEB 9.5-1 C.5(5)規定:Door openings in fire barriers should be protected with equivalently rated doors, frames, and hardware that have been tested and approved by a nationally recognized laboratory。
BTP CMEB 9.5-1 B.4規定:Fire Barrier – those components of construction (walls, floor, and their), including beams, joists, columns, penetration seals or closures, fire doors, and fire dampers that are rated by approving laboratories in hours of resistance to fire and are used to prevent the spread of fire.

二、經查龍門電廠裝設之防火門許多不具耐火時效認證標籤,此顯示所裝設之防火門其耐火時效未經獲認可實驗室之測試驗證,且其防火時效未確認與防火屏障同等級,例如1號機之FMCRD維修區、RWCU樹脂維持泵A及過濾除礦器閥室、放射性洩水閥室等(如附圖一至三),此不符BTP CMEB 9.5-1 C.5.a(5)及BTP CMEB 9.5-1 B.4之規定,對所列不符情事,請針對FSAR 9.5.1(8)所列廠房之防火門逐一檢討改正。
