二、Vogtle核电站工程进展评述

  上半年主要工程进展本博主已在(http://blog.sina.com.cn/s/blog_55e07e640102uz80.html)介绍,这里仅介绍监管机构评估报告中的主要关注点:

1、The EPC Agreement is nearly 100 percent fixed or firm; therefore, the Contractor is strongly incentivized to complete construction of the Facility as expeditiously as possible. The Company expects the Contractor to employ all possible means to meet the current schedule targets; however, schedule pressures continue to challenge the project. The Company will continue its transparent reporting to this Commission, the Construction Monitor and the PSC Staff as the Contractor completes its schedule analysis for activities beyond 2015.
EPC协议是接近100%的固定或固化的。因此承包商有强烈的意愿来尽可能快的完成电站建设。公司希望承办商采用尽可能的手段来达到当前的计划目标(博主备注:工期已有所延误);然而进度压力将给项目带来持续挑战。一旦承包商在2015年前完成计划分析,公司将继续透明地向本委员会、建造监管者和PSC职员报告。

2、The Total Construction and Capital Cost forecast remains unchanged since the previous reporting period.

与前次报告期相比,总建造成本和财务成本预测保持不变

3、The assembled CVBH was lifted and set by the Heavy Lift Derrick in the nuclear island on May 8, 2014, only 11 months following the placement of the Unit 3 CVBH.In April 2014, the first Auxiliary Building wall placement was completed, only eight months following the first Unit 3 Auxiliary Building wall placement.

在#3机组CVBH就位后仅11个月之后,#4机组就完成了CVBH就位;在#3机组辅助厂房墙体就位后仅8个月之后,#4机组辅助厂房墙体就位。(博主批注:充分吸取了#3机组的经验,#4机组比#3机组要高效一些

4、Fabrication of all major components continues to meet project needs.

所有主设备制造继续满足项目需要。

5、During testing of the Unit 3 reactor coolant pumps, issues with pump performance were found. A causal analysis determined the reasons for the issues and the needed design modifications of certain pump components. Design modifications have been incorporated into the pump components and validation testing is underway with endurance tests to follow to prove successful resolution. The Unit 3 reactor coolant pumps are needed for installation in the Facility in 2016, and delivery of the pumps after successful testing and documentation review is scheduled for 2015.

在#3机组反应堆冷却剂泵测试期间,发现了主泵性能方面的问题。目前正在分析确诊导致问题的原因所在并对某些泵部件进行必要的设计修改。被采纳的泵部件设计修改和耐久性试验正在进行中,以确保试验问题最终解决。#3机组反应堆冷却剂主泵需要在2016年在核电厂安装,在试验成果并通过文件审核后,按计划2015年主泵发运。(博主批注:美国AP1000项目的主泵和中国项目的主泵采购是一致的,不同的是由于美国项目晚开工,对其整体进度的影响是可控的

6、Additionally, the material traceability issue discovered in 2013 with critical passive core cooling valves, named squib valves, is being resolved with replacement parts that have been procured. Testing of the squib valves revealed issues with their design, and the re-design of the suspect areas within the valves is near completion. Additional testing will be performed after the design modifications are implemented into the valves to ensure they will perform their intended function.

此外,被称为爆破阀的重要非能动堆芯冷却阀于2013年发现了材料的可追溯性问题,目前正在通过采购替换部分来解决。爆破阀测试将解决相关的设计问题,阀门内受到质疑的部分进行的重新设计接近完成。设计修改后需要进行的附加试验将确保阀门执行他们的预期功能。(博主批注:爆破阀部分再设计完成,待测试
7、 On August 30, 2013, the District Court for the District of Columbia granted the Owner’s motion to dismiss the Contractor claim in that Court, thereby allowing the litigation to proceed in the Southern District of Georgia. The Contractor filed an appeal of the District of Columbia Court’s decision on September 27, 2013. Briefing on Contractor’s appeal before the U.S. Court of Appeals for the District of Columbia Circuit has concluded, and oral argument has been set for October 2014.
On May 22, 2014, the Contractor amended its counterclaim in the Southern District of Georgia, updating its original claims relating to the structural modules and adding a claim related to delays in rebar installation which occurred in 2012. While discovery and other pre-trial preparation in the Southern District of Georgia remain ongoing, and the Company is vigorously asserting its positions and defending against Contractor’s claims, the Company expects negotiations with the Contractor to continue with respect to cost and schedule. It is possible that during these negotiations the parties may reach a mutually acceptable compromise of their positions. The Company is not proposing any change to the certified capital cost for settlement of the Contractors’ claims that are currently subject to litigation in federal courts.

2013年8月30日,哥伦比亚特区地方法院同意了业主驳回承包商在该法院索赔起诉的请求,并允许在佐治亚州南地方(法院)继续审理。2013年9月27日,承包商提交了哥伦比亚特区地方法院判决的上诉。在美国哥伦比亚特区巡回上述法院就承包商上诉进行简单了解前,2014年10月将进行口头辩论。2014年5月22日,承包商向佐治亚州南法院修改了起诉书,更新了结构模块相关的起诉并追加了发生在2012年期间在绑扎钢筋安装期间延误相关的起诉。随着佐治亚州南法院调查和其他预审准备还在进行,公司在大力举证并对承包商索赔起诉进行应对,公司期望和承包商继续就成本和进度进行谈判。有可能在谈判期间双方达成各自能接受的某种妥协。公司不打算因解决承包商提交给联邦法院起诉的索赔问题改变注册资本。(博主批注:国外公司的法律意识和经营意识多很强,值得中国学习
