 14 November 2012 EOn continues to struggle under German energy policy, with gas generation made "barely profitable" by pro-renewable market arrangements and nuclear generation slashed and taxed by government decree. The utility has summarised its performance from January to the end of September, explaining to shareholders that it would honour dividend predictions for 2012, but would revise ambitions for 2013 and 2015. Despite a worsening outlook, the company still recorded pre-tax earnings of €8.8 billion ($11.2 billion) with 'underlying net income' of about €4 billion ($5.0 billion) for the first nine months of 2012. One problem is that renewable generation is given priority access to the grid when it is available. This sometimes prevents gas-fired generation from operating during peak hours and has altered the economics of gas to such an extent that it is now "barely profitable to operate," said CEO Johannes Teyssen. "In most European markets, the gross margin for gas-fired units is approaching zero or is indeed already negative." . . . .
This an example of a poor energy and economic policy on the part of the German government, and it is harming the economy.
 PF Patron P: 751 German energy policy is constrained by anti nuclear sentiment on the one hand (fuelled by media support of a small cadre of activists plus public distrust sustained by unrelenting publicity focused on the nuclear industry's failures) along with the recognition that gas supply from Russia is unreliable (it was turned off just a couple of winters ago). The fix is more coal fired power, because the 'green' alternatives are falling well short of requirements for reliability and quantity.

In 3000 rpm turbines, the last stage blade length is on the order of 1.35 m http://www.rwe.com/web/cms/mediablob...power/blob.pdf

Bethlehem-based Lehigh Heavy Forge Corp. teaming with N.C. company to make nuclear reactors
http://www.lehighvalleylive.com/beth...eaming_wi.html
 Bethlehem-based Lehigh Heavy Forge Corp. expects to add 100 jobs over the next 10 years through a partnership announced today with a North Carolina nuclear technology company. The South Side foundry is teaming with the Babcock & Wilcox Co. to supply forgings for a new brand of small modular reactors being developed by B&W. Officials announced the partnership at an event joined by Pennsylvania Gov. Tom Corbett and local business and government officials. . . . .

Vogtle 3 and 4 and V C Summer 2 and 3 (both twin AP1000 sites) are under construction.

Vogtle has been doing ground work for sometime.

On March 9, pouring of the basemat for Unit 2 commenced. It lasted about 50 hours as a continuous pour.

 The basemat provides a foundation for the containment and auxilary buildings that are within the unit's nuclear island. Measuring 1.8 metres thick, the basemat required some 5350 cubic metres of concrete to cover an area about 76 metres by 49 metres. The concrete-pouring process took just over 50 hours and was completed at about 10.00am on 11 March.

Update: March 13, 2013

Southern Nuclear began pouring the basemat at Vogtle 3, a day after SCANA/SCE&G began the pour at Summer 2. It takes about 50 hours to pour the basemat.

http://chronicle.augusta.com/news/me...tor-foundation

Southern Nuclear has begun pouring of specially designed basemat concrete for the foundation of its Unit 3 Plant Vogtle reactor, just three days after similar steps were completed at SCANA’s V.C. Summer plant in South Carolina.

http://chronicle.augusta.com/news/me...nt-vogtle-site

(Jan 24) The reactor vessel head, weighing 160 tons, serves as the “lid” of the Unit 3 reactor and will be bolted to the even-larger reactor vessel body – a 300-ton component that remains in Savannah, Ga., awaiting shipment to the site aboard a specially built rail car.
