How to make nuclear power affordable
11 January, 2018
The much vaunted “nuclear renaissance” has not worked out as planned, with projects running many years behind schedule and hugely over budget. A major concern about nuclear power used to be safety now it is also affordability. Conventional nuclear power plants are too big, take too long to construct and are much too expensive. As a near term remedy, small modular reactors, based on well established technologies such as the PWR, look promising.Tony Roulstone

The UK new build programme – does it make any sense?
13 June, 2017
Not at all, says Steve Kidd (East Cliff Consulting), who points to the disadvantages of pursuing a number of different reactor designs rather than having one proven standardised plant replicated across as many projects as possible.

Germany sets course for 2 GW of new offshore capacity in 2015
01 June, 2015
Not surprisingly German offshore wind has had no shortage of teething problems, but 2015 seems to be proving productive for projects in the German North Sea, with seven large (300-400 MW range) wind farms in various stages of start up/commissioning. These, when fully commercial, will add some 2071 MW to Germany’s North Sea offshore wind installed capacity, taking the total from about 856 MW (including Blackstone-financed Meerwind Sud/Ost (288), the troubled Bard Offshore One (400 MW), Riffgat (108 MW) and Alpha Ventus (60 MW test facility)) to nearly 3 GW (the current stated goal for offshore wind installed capacity being 6.5 GW by 2020 and 15 GW by 2030).

Full steam ahead for Flamanville 3 EPR turbine island construction
01 May, 2010
The 1750 MWe ARABELLE™ turbine generator is the world’s largest engine. The first such machine in Europe is currently under construction at EDF’s Flamanville 3 site. The turbine island at Flamanville 3 has now progressed from the manufacturing phase to construction, with the focus currently on site work and installation of major components.

Bridging the Brazilian power gap
01 January, 2010
The development of Brazil’s power infrastrucure has broken several world records. The next one will fall in 2012 when the world’s longest HVDC interconnector comes on line.

Trianel demonstrates the power of working together
01 January, 2010
Trianel, representing municipal utilities in Germany and elsewhere, has an 848 MWe combined cycle plant in operation, an 800 MWe supercritical coal fired unit under construction, and two more ambitious projects under planning: a second 800 MWe coal station and a 400 MWe offshore wind farm.

Corona shields for thyristor valves at ultra-high voltages
01 May, 2009
UHVDC operating levels present a particular challenge for the insulation of thyristor valves. AREVA T&D’s R&D teams have carried out electric field stress studies to determine the best profile for the corona shields, built a test object and subjected it to DC and switching impulse tests that validated the theoretical model. The end result after the next phase of development will be a new design of corona shield, suitable for DC applications up to 800 kV.

Dealing with tube cracking at Herdecke and Hamm-Uentrop
01 October, 2008
Countermeasures have been successfully implemented to address tube cracking in the HP Evaporator 2 sections of the HRSGs at Herdecke and Hamm-Uentrop. These are of the Cottam type, an innovative BensonTM design with low mass flux vertical tubes in a horizontal exhaust flow.

Transforming failure to success in 22 days
01 May, 2008
When two of its three generator transformers at the 1.5 GW coal fired Aberthaw power station failed in quick succession, owner RWE found itself under extreme pressure to restore the 600 MVA, 275/22 kV units to service as quickly as possible without compromising technical quality and safety.
