一、依App. R III.H之要求,「The qualification of fire brigade members shall include an annual physical examination to determine their ability to perform strenuous fire fighting activities」。核三廠程序書107,在第5.6.4節、第5.6.5節有關測驗及體檢未訂有明確之及格標準。建議核三廠應依據相關要求,將相關合格標準納入程序書並據以執行。
二、依App. R III.I.1.b之要求,「The instruction shall be provided by qualified individuals who are knowledgeable, experienced, and suitably trained in fighting the types of fires that could occur in the plant and in using the types of equipment available in the nuclear power plant」。核三廠程序書107,在第5.9節有關講師資格未依相關要求訂有明確之說明。建議核三廠應依據相關要求,將相關講師資格納入程序書並據以執行。
三、依App. R III.I.1.c之要求,「Instruction shall be provided to all fire brigade members and fire brigade leaders」。核三廠程序書107,在第5.6.1節初始課堂講授,僅第(8)項包括消防隊隊長及消防隊小隊長。惟上課紀錄顯示,僅各小隊(8名成員包括小隊長)參與初始課堂講授。建議核三廠應依據相關要求,將相關課程參與人員納入程序書並據以執行。
四、依App. R III.I.1.d之要求,「Regular planned meetings shall be held at least every 3 months for all brigade members to review changes in the fire protection program and other subjects as necessary」。核三廠程序書107,在第5.6.3節之內容符合以上要求。惟查證相關紀錄顯示核三廠現行做法(例如:參與成員、頻率、內容之符合性等)與上述要求並未一致。建議核三廠應依據相關要求,落實並據以執行程序書。
五、依App. R III.I.3.c之要求,「Unannounced drills shall be planned and critiqued by members of the management staff responsible for plant safety and fire protection」。核三廠程序書107,在第5.7.3節說明無預警演練應由負責安全及火災防護之管理階層負責規劃及評核,符合以上要求。惟查證相關紀錄顯示,核三廠現行做法,在評核人員部份未納入負責機組安全之管理階層。建議核三廠應依據相關要求,落實並據以執行程序書。
六、依App. R III.I.3.c之要求,「Performance deficiencies of a fire brigade or of individual fire brigade members shall be remedied by scheduling additional training for the brigade or members. Unsatisfactory drill performance shall be followed by a repeat drill within 30 days」。核三廠程序書107,在第5.7.3節說明消防隊或個別成員之缺失應由額外之訓練來導正改善,消防演練不符合要求部份應在30天內再演練,符合以上要求。惟查證相關紀錄顯示,核三廠現行做法,並無法適切追蹤再演練執行情形。建議核三廠應依據相關要求,落實並據以執行程序書。
七、依App. R III.I.3.d之要求,「At 3-year intervals, a randomly selected unannounced drill must be critiqued by qualified individuals independent of the licensee's staff」。核三廠程序書107,在第5.7.4節說明每3年辦理不預警演習,符合以上要求。惟查證相關紀錄顯示,核三廠前次不預警演習(102年1月辦理),台電公司僅邀請縣府消防局科長擔任外部評核委員,其餘評核委員係台電公司內部人員,此做法無法滿足上述要求。建議核三廠應依據相關要求,落實並據以執行程序書。本會在注意改進事項(編號AN-MS-101-022)亦針對不預警演習,提出邀請不同專家,以廣納意見之建議。
八、依App. R III.I.3.d之要求,「A copy of the written report from these individuals must be available for NRC review and shall be retained as a record as specified in section III.I.4 of this appendix」。核三廠程序書107,在第5.7.4節說明評核報告可供原能會查閱,且依規定紀錄保留備查,據以改善。惟查證相關紀錄顯示,核三廠前次不預警演習(102年1月辦理),台電公司僅提供核三廠「附件一建議改善事項」,無法滿足上述要求。建議台電公司應依據相關要求,修訂「消防訓練督導工作計畫」有關每3年辦理不預警演習部份,納入程序書並據以執行。
九、依App. R III.I.3.e.(4)之要求,「Assessment of brigade leader's direction of the fire fighting effort as to thoroughness, accuracy, and effectiveness」。核三廠程序書107,在第5.7.6節說明消防演練最少應包含所列之三項事項,遺漏App. R III.I.3.e.(4)之要求。建議台電公司應依據相關要求,納入程序書並據以執行。
十、依App. R III.I.4之要求,「Individual records of training provided to each fire brigade member, including drill critiques, shall be maintained for at least 3 years to ensure that each member receives training in all parts of the training program. These records of training shall be available for NRC review. Retraining or broadened training for fire fighting within buildings shall be scheduled for all those brigade members whose performance records show deficiencies」。核三廠程序書107,在第5.10節說明每位成員之訓練紀錄(包括演練評語)應依SOP 115表10填列,並陳主管副廠長核章後,保存至少3年,惟查證目前做法並未完全符合上述要求。建議台電公司應依據相關要求,納入程序書並據以執行。
「電氣組件壽命重估作業」
十一、依據IEEE Std 323-1974第6.3.3節Aging所述,除溫度、輻射造成之老化外,「Electromechanical equipment (motors, relays, etc) shall be operated to simulate the expected mechanical wear and electrical contact degradation (for example, contact pitting) of the device to be type tested」。另在設備合格驗證集冊(Equipment Qualification Documentation Package, EQDP)文件中,西屋公司驗證之加速老化亦有Mechanical Aging(cyclic)一類。經查程序書1106.05「設備壽命重估程序書」僅針對溫度、輻射造成之老化重估其驗證壽命(Qualified Life),請檢討壽命重估程序之完整性。
十二、IEEE Std 323-1974第6.6節On-Going Qualification,提及設備之Qualified Life若小於電廠之設計壽命,則可進行On-Going Qualification,且敘述「This procedure shall be repeated until the qualified life equals the required installed life of the equipment」。經查程序書1106.05「設備壽命重估程序書」,於溫度老化壽命重估計算係採用設備環境溫度實測值來直接計算Qualified Life,而設備壽命重估後即未再持續追蹤該設備環境溫度之變化。在未有定期重新評估之機制下,若設備環境溫度於重估後有升高,Qualified Life將趨於不保守。本項請提出定期重估方式,以確保Qualified Life計算之準確性;有關輻射、cyclic之考量亦請納入。
十四、依IEEE Std 323-1974之第6.3.1.5節Margin敘述「Suggested factors to be applied to service conditions for type testing are as follows : (3) Radiation : + 10 percent (on accident dose)」。經查程序書1106.05「設備壽命重估程序書」之輻射老化壽命重估計算式,未依IEEE Std 323-1974建議將設計基準事故(Design Basis Event, DBE)輻射劑量乘以1.1倍,造成輻射老化壽命重估計算結果未留有餘裕,請檢討改進。
十五、依NRC RG 1.89 C. REGULATORY POSITION之第2.c.5項「Electric equipment that could be exposed to radiation should be environmentally qualified to a radiation dose. … Such qualification should consider that equipment damage is a function of total integrated dose and can be influenced by dose rate, energy spectrum, and particle type」。經查程序書1106.05「設備壽命重估程序書」之輻射老化壽命重估計算,於「DBE事故的輻射劑量(F)」項未要求考量各種游離輻射源,以致壽命重估案EQL-IN1-C、EQL-IN1-G、EQLE-M-102001…等,其輻射老化壽命重估僅計算FSAR Table 3-11-5所列之Gamma劑量,未將Beta劑量列入計算,請檢討改進。
二十二、依RG 1.89電氣設備清單項目包括:a. Switchgear. b. Motor control centers. c. Valve operators and solenoid valves. d. Motors. e. Logic equipment. f. Cable. g. Connectors. h. Sensors. i. Limit switches. j. Heaters. k. Fans. l. Control boards. m. Instrument racks and panels. n. Electric penetrations. o. Splices. p. Terminal blocks.經抽查發現EQ List未包含cable、connectors及splices等,請檢討是否還有其他未涵蓋項目。
