Construction Timeline 3rd Quarter 2013
With a project of this magnitude, almost every day reveals a major milestone and historic achievement as we witness America's rebirth of nuclear energy here at Georgia Power's Plant Vogtle!
Some big things are happening here… REALLY big!
This is the 900-ton containment vessel bottom head for Unit 3. It was lifted and placed onto its cradle in Unit 3's nuclear island recently making this the heaviest lift to date here.
The bottom head is the first of several components that will make up the thick steel structure known as the containment vessel. This is where the reactor and associated steam generators and components will be housed. This bottom head was assembled on site in the containment vessel assembly area… …where we can see that work on the Unit 4 bottom head is well underway. Each bottom head is comprised of fifty-eight plates that are welded together. And next to it we can see the progress on the middle and lower rings for Unit 3.
Once all the components of the containment vessel are in place, it will be surrounded by heavily reinforced concrete to create the shield building. Right now, the CA20 module for Unit 3 - which will be placed adjacent to the containment building - is being welded in the Module Assembly Building. The CA 20 module houses equipment for used fuel storage and handling, and various other reactor operation support systems. When complete it will be equivalent in height to a five-story building, and will be the single largest component used in the construction of the AP1000 units. The containment buildings for Units 3 and 4 will each be connected to their respective turbine buildings.
And in the past couple of days we've seen the Unit 3 turbine building rise from the Georgia clay and begin to take shape. It's exciting when structures here go vertical.
It also makes heads turn when mammoth components like this deaerator for Unit 4 arrive on site.
Everyone looks forward to milestones like these as we are living a little piece of history here every day at Vogtle 3 & 4.
To date there are two thousand six hundred fifty workers on site, and that number is expected to grow with the project. There are many different kinds of jobs and specialties here, and Quincy Robinson can tell us more about that.
There are a lot of opportunities here as far as different crafts. Electrical craft, carpenters, concrete finishers, ironworkers, pipe fitters, and all these crafts offer apprenticeship programs which consist of three to five years on the job training and get paid at the same time, and it's a great opportunity for the future. This is the turbine three area here at Plant Vogtle. This is the actual area where I work with the rodbusters. carpenters, laborers, surveyors…the rodbusters are the guys that's doing all the ties. This is a very important role as far as getting this steel in. It has to be done. Then it's pour the concrete and we can further the progress of the project.
Thanks Quincy. Every single person who works at this construction site is focused on safety. CB&I's Project Director for Vogtle 3 & 4, John Simmons, has more than 35 years of design, construction and project management experience and he's responsible for ensuring the project is completed safely while meeting the objectives for quality, schedule and cost.
We have been in a ramp up phase for the last 4 to 5 months on the project. We've added 250 workers over the last 3 months - most of those workers are supporting our concrete work and module installations work. A lot of welders are being added to the project and it's great to see the mix of the workers that are coming to this site from Georgia - a lot of younger workers are coming in and that's great for the local economy and we like to get that mix in here also. We're going to be continuing work in the aux. building and the containment. We just placed the first nuclear walls. That work is going to be continuing. We just placed the first mechanical equipment. That work will be continuing. We're going to be placing consolidated concrete, that's coming up. And the other thing that's going to be happening is we're going to be setting the condensers in unit 3 and that's going to be a very large pick.
Thanks John. Together with consortium partner CB&I, Westinghouse - the designer of the AP1000 - is responsible for the successful execution of the engineering, procurement and construction contract for the project, which is more than 50 percent complete based on contractual milestones. Scott Gray, Vice President for the Vogtle 3 & 4 AP1000 project for Westinghouse has more.
We're targeting two major activities, at least. One being the setting of the CA20 structural module in Unit 3 auxiliary building. The other significant milestone will be concrete placement - first nuclear concrete - for Unit 4 basemat. Over the next six months our goal is to achieve Elevation 100 which is the surface level surrounding the nuclear island which allows us to start the construction of, for example, the annex building which will be used later on to install equipment which supports initial energization and startup activities. We have a very collaborative working environment within the consortium. We work very closely together; make decisions together in the best interest of the project. We work very closely with our customer, Southern Nuclear, to address all the critical issues everybody is interested in and is important to the construction of the project. The key to our success, whether on an individual activity basis or for the project as a whole, is the commitment we've made to a strong nuclear safety culture, to the safety of our personnel and the quality of our work - doing it right the first time and continuous improvement.
Every activity here is performed with Georgia Power's uncompromising commitment to safety, as well as the Nuclear Regulatory Commission's oversight to ensure all safety goals are met.
NRC inspectors are on site here full time, at the Vogtle 1 &2 operating facility as well as at the construction site for Units 3 & 4.
And recently, Nuclear Regulatory Commission Chairman Allison Macfarlane toured Plant Vogtle and expressed confidence that safety objectives are being met here.
Construction here continues to be well-managed and is progressing toward Georgia Power's goal of providing a safe, reliable, clean and cost-effective source of electricity for today, and for generations to come.
That's all from here for now. Join us again for the next Vogtle Timeline!
