News Updates

•Luminant has requested a suspension of the NRC’s review of its Comanche Peak Combined Construction and Operating License (COL) application. The company cited impacts to the review schedule of the Mitsubishi Heavy Industries US Advanced Pressurized Water Reactor (US-APWR) due to the vendor’s desire to refocus its resources to reactor restarts in Japan as well as low electricity prices driven by low natural gas prices as reasons for the suspension.
•Unistar Nuclear Operating Co. has formally withdrawn its COL application from the Nuclear Regulatory Commission (NRC) to build and operate Areva’s U.S. EPR at its Nine Mile Point site in Oswego, NY. In late 2009, Unistar requested a suspension of the application review due to financial concerns. Low electricity prices and inability to obtain a loan guarantee for the project were factors in Unistar’s decision to withdraw the application.
•The NRC has formally extended the expiration date of the construction permit for the Watts Bar 2 reactor to September 2016. Tennessee Valley Authority (TVA) requested the extension in 2012 following lower than expected initial construction productivity and to allow for additional time to address regulatory changes resulting from the Fukushima Daiichi accident. TVA’s “most likely estimate to complete” date remains December 2015.
•The Department of Energy announced an award to NuScale Power LLC in December to support a new project to design, certify and help commercialize innovative small modular reactors (SMRs) in the United States. The NuScale Power Module design allows for incremental units of 45MWe to be constructed up to a maximum of 540MWe (12 units) at a given plant.

新聞更新

Luminant（Comanche Peak 核電站業(yè)主）已要求NRC暫緩對Comanche Peak核電站建造和運營聯(lián)合申請的審查。

•主要原因一是三菱重工將資源用於日本國內(nèi)重啟而推遲了US-APWR的（DCD）審查，二是由于低天然氣價格導致的電價較低。
•Unistar核電運營公司正式從NRC撤銷了在紐約州Oswego的九英里角廠址（擴建廠址）建設(shè)和運營US-EPR的COL申請（2009年底，Unistar基于財務問題推遲了該COL申請），撤銷的主要原因是電價低且沒有能夠為項目爭取到貸款擔保。

•NRC正式將Watts Bar2反應堆的建造許可證延期到2016年9月。田納西河流域管理局（TVA，Watts Bar核電站業(yè)主）估計將會在2015年12月前完成建造。

•能源部（DOE）在2013年12月授予NUsclae電力公司一項關(guān)于革新型小型模塊式反應堆（SMR）設(shè)計、測試和商業(yè)化的項目，Nuscale模塊設(shè)計允許在一個廠址用45MWe的單元來建造最大達540MWe的機組。

Regulatory Status

•Eighteen Combined Construction and Operating License (COL) applications have been docketed, eight of which (totaling 12 nuclear reactors) remain under active NRC review.NRC reviews of eight applications were suspended due to utility economic considerations.Review of the Fermi and South Texas Project applications could continue after submittal of additional technical information; in addition, the South Texas Project and Calvert Cliffs applications face foreign ownership issues.The Reference COL (R-COL) application has been submitted for five reactor designs; subsequent COLs (S-COLs) will incorporate the corresponding R-COL application by reference, noting any site-specific departures. Southern Nuclear’s Vogtle Units 3 and 4 and SCE&G’s VC Summer Units 2 and 3 have received COLs.
規(guī)管狀態(tài)

•登記在案的有18份COL申請，其中的8份（總計12座反應堆）NRC仍在審查。NRC審查的8份申請因經(jīng)濟考量推遲。Fermi和South Texas項目的申請在補交附加的技術(shù)信息后將可以繼續(xù)；另外South Texas和Calvert Cliffs項目申請還面臨外國股權(quán)問題。參考COL（R-COL）申請已提交了五中設(shè)計；隨后的COL（S-COLs）將會依據(jù)廠址特性對R-COL進行修正。南方核能的Votle以及南卡州電力燃氣公司的VC Summer#2、3機組已經(jīng)收到了COLs。

Summary:Two reactor designs that are being considered for future builds in the U.S. are certified and two renewal applications are under NRC review.

•AREVA U.S.-EPR – Submitted December 12, 2007 and docketed February 25, 2008; certification schedule is under review.
•GE-Hitachi (GEH) ESBWR – Final Design Approval in March 2011; rulemaking expected 2014.
•Mitsubishi Heavy Industries US-APWR – Submitted December 31, 2007 and docketed February 29, 2008; MHI has requested a deferral of the review due to their work on reactor restarts in Japan.
•Korea Electric Power Corporation (KEPCO) APR1400 – Pre-application interactions continue. Design certification application submitted on September 30, 2013; NRC declined to docket the application at this time due to lack of sufficient technical detail.
•GEH ABWR – Certified in 1997. Toshiba and GEH have also separately submitted Design Certification renewal applications that are currently under review.
•Westinghouse AP1000 – Amended design certified on December 30, 2011.

Fabrication and testing of step up transformers has been completed. Cooling tower 2A structural work is substantially complete.
•Unit 3: Nuclear island basemat placement is complete. Construction of unit 3 CVBH is underway. Work is continuing on the cooling towers. Critical path for completion of both units continues to be defined by progress in delivery of submodules from the Chicago Bridge and Iron (CB&I) Lake Charles facility and module assembly and completion of concrete structures on site.

•Dominion設(shè)定了North Anna 3投運“最早可能”時間為2024年。

博主微評：

1、從整體上來看，無論是美國政府，還是企業(yè)或核電設(shè)備制造商，對核電安全是充滿自信的，有發(fā)展的信心。無論是大型商用反應堆還是小型模塊式反應堆都受到了重視。

2、部分核電項目建設(shè)計劃延遲，甚至取消，從中我們可以看到美國頁巖氣革命帶來的影響（氣價、電價下降導致了經(jīng)濟競爭性問題）。美國核電的發(fā)展規(guī)模取決于經(jīng)濟方面的考量。

3、美國對外資進入其國內(nèi)核電領(lǐng)域管制很嚴。

4、AP1000計劃比預期有所滯后。
