【美國核管會回信核電廠與斷層距離】
#別再相信資深反核人士的謠言 #寫信去問NRC囉
大概兩個月前寫信去給美國核管會NRC,今天打開信箱發現他們在我生日休假那天回信了XDD,人生成就解鎖(1/1 美國核管會回覆信件)。
我主要是想詢問到底核電廠選址與斷層的距離是否有清楚的規範?答案是 #沒有規定電廠選址與斷層的距離到底要多少或禁止核電廠建置於斷層周邊,而是要求特定距離的核電廠設施必須做地質危害評估以及禁得起地震考驗這樣。台灣也有做SSHAC,但還沒看到正式出爐的報告(就陳大教授搶先披露那個)。
然後她詳細列了一堆NRC評估核電廠附近能動斷層的步驟以及法條,我相信陳教授或DPP不分區第二名應該都沒看過任何一條啦。

Dear Mr. Chen,
Thank you for your questions related to whether the NRC has regulations that state how far a nuclear power plant (NPP) should be located from a fault that might move and cause earthquakes. The following paragraphs respond to your questions. As you requested, this response also cites NRC regulations that explain how the NRC analyzes potential hazard at a NPP resulting from earthquakes caused by movement along a fault located near the NPP.
#這段很重要
The US NRC does not have a regulation that specifies the distance required between a fault and a nuclear power plant (NPP). However, in Title 10 of the Code of Federal Regulations (10 CFR), specifically 10 CFR Part 50 (Domestic Licensing of Production and Utilization Materials), Appendix A, Criterion 2, the NRC requires safety-related structures, systems, and components (SSCs) of a NPP to be designed to withstand the effects of natural phenomena such as earthquakes without losing the capability to perform their safety functions.
美國NRC沒有規定斷層和核電廠(NPP)之間所需距離的法規。但是,在聯邦法規(10 CFR)的標題10中,尤其是10 CFR第50部分(生產和使用材料的國內許可)附錄A,準則2中,NRC要求與安全相關的結構,系統和組件( NPP的SSC)旨在承受地震等自然現象的影響而又不喪失執行其安全功能的能力。
As defined in 10 CFR Part 50, Appendix S (Earthquake Engineering Criteria for Nuclear Plants), a Safe Shutdown Earthquake (SSE) is the vibratory ground motion for which certain SSCs must be designed to remain functional if an earthquake occurs. 10 CFR Part 100.23(c) (Geological, Seismological, and Engineering Characteristics) requires that geological, seismological, and engineering characteristics of a site and its environs be investigated in sufficient scope and detail to permit an adequate evaluation of the proposed site, provide sufficient information to support evaluations performed to estimate the SSE vibratory ground motion, and permit adequate engineering solutions to actual or potential geologic and seismic effects at the proposed site. Part 100.23(d) (Geologic and Seismic Siting Factors) requires that geologic and seismic siting factors considered for design include a determination of the SSE vibratory ground motion for the site and the potential for surface deformation due to faulting (i.e., tectonic deformation of the ground surface). Part 100.23(d)(1) (Determination of the Safe Shutdown Earthquake Ground Motion) requires that uncertainties in SSE vibratory ground motion estimates be addressed through an appropriate analysis (e.g., a probabilistic seismic hazard analysis, or PSHA) with due consideration for the geologic characteristics specified in 10 CFR Part 100.23(c). For a fault that is considered to be a potential source of earthquakes (i.e., a seismic source), that geologic feature can be analyzed using the Senior Seismic Hazard Analysis Committee (SSHAC) process. That process is a formal approach for incorporating information about the fault into a model used to characterize the fault as a seismic source, which is analyzed as part of the SSHAC process.
In Regulatory Guide 1.208 (A Performance-Based Approach to Define the Site-Specific Earthquake Ground Motion). the NRC provides guidance for applicants and licensees regarding how to meet the regulatory requirements discussed above. In addition, criteria for NRC staff to review applications for constructing and operating a nuclear power plant related to geologic, seismic, and geotechnical site characteristics are found in Chapter 2.5 of NUREG-0800, the NRC’s Standard Review Plan. If assessment of the potential for surface deformation must be considered because a fault is located such that it could result in surface rupture at the NPP site and deformation of engineered plant structures as required in 10 CFR Part 100.23(d), guidance for evaluating surface deformation is provided in NUREG-0800, Chapter 2.5.3. NUREG-2213 presents updated implementation guidelines for SSHAC studies in case you might wish to learn more about that process.

📢📢恭賀土木系蔡克銓教授獲頒AISC Special Achievement Award
土木系蔡克銓教授因長期與美國學者合作,從事鋼結構設計規範中多種耐震構架系統的大型抗震性能驗証實驗,於2018年4月11在美國馬里蘭州巴爾的摩市,接受美國鋼構造協會理事長Dr. Charles J. Carter,在超過五千人與會的北美洲鋼構造研討會中頒發「特殊成就獎」。
The AISC Special Achievement Award recognizes individuals who have demonstrated notable achievements in structural steel design, construction, research or education. It honors those who have made a positive and substantial impact on the structural steel design and construction industry. This year's award recipients include:
Keh-Chyuan Tsai, SE, PhD, professor of civil engineering, National Taiwan University. Tsai is being recognized for his extensive work with U.S. researchers to conduct large-scale system level testing of structural steel seismic force resisting systems, leading to system level verification of many of the AISC 341 provisions.

「未來之村」就是當初大地震我人在尼泊爾時,真的是歷經千辛萬苦才在千鈞一髮之際把我募集到的善款交到創辦人手上的那個受贈單位。大地震之後他們整個村子幾乎全毀,而重建之路非常漫長也非常需要幫助。
在關注巴黎攻擊、敘利亞難民之餘,不要忘記尼泊爾人民震後所需要的幫助。學著持續關懷各地的弱勢不隨波(媒體)逐流,才能保持獨立思考的能力。
現在你也可以為「未來之村」的重建盡一份心力了,哪怕是一塊錢也好,那對他們來說都是珍貴且感謝的。點擊下面這個網址就可以進行捐款喔!

''Build the home . Build the Future'' Local House Rebuild Project「築 ● 動未來」 房屋重建計劃正式啟動
Joint hands with IDEA Foundation (Hong Kong) & Design for People Co., Ltd -Hsieh Ying Chun Architects & People's Steel (Taiwan & Chengdu), the local house rebuild project in Katunge region ward 9 is ready to start!
未來之村(尼泊爾)聯同人人設計(香港)及常民建築 - 謝英俊建築師事務所(台灣及成都),一同為尼泊爾Katunge第九區的村民重建房屋。
The three parties had arranged a site visit trip and meeting during 7-10 November in Chengdu, China. The lightweight steel structural system with excellent seismic resistance (resist earthquakes up to 9 Richter magnitude) will be employed for reconstruction project. The self-build with instruction practice shall utilize the local manpower and preserve local craftsmanship and local culture.
三個團隊在11月7至10日期間於成都進行會議及考察,所選用之輕鋼架設計可抵禦九級地震,同時以村民「協力造屋」為本的設計理念可揉合當地傳統建築工藝、村民善用當地資源、在簡單指導下可自行建設房屋。
Stay tuned with us! More details will be introduced in coming days!
請緊貼我們,未來將會發放進一步的消息及介紹。
And, please take action to support our project through online fundraising campaign.Every penny counts!
