New reactor head ready for Davis-Besse
Final work on the reactor head was completed in France, including the installation of control rod drive mechanism nozzles made of material less susceptible to cracking under high temperatures and pressures. The head measures nearly 17 feet in diameter, is eight-feet tall and weighs more than 82 tons. A comprehensive pre-service inspection was conducted by FENOC personnel before the head was shipped from Antwerp, Belgium, on November 5.
The new reactor head will be placed in a specially constructed building at Davis-Besse where new control rod drive mechanisms and other components will be fitted before installation takes place in the fall of 2011.

Rolls-Royce signs MoU with Exelon for compact nuclear power stations
LONDON - Rolls-Royce and Exelon Generation have signed a Memorandum of Understanding to pursue the potential for Exelon Generation to operate compact nuclear power stations both in the UK and internationally.
Exelon Generation will be using their operational experience to assist Rolls Royce in the development and deployment of the UKSMR.
Rolls-Royce is leading a consortium that is designing a low-cost factory built nuclear power station, known as a small modular reactor (SMR). Its standardised, factory-made components and advanced manufacturing processes push costs down, while the rapid assembly of the modules and components inside a weatherproof canopy on the power station site…
