Concrete started to be poured at 6.24am on 11 December. Over the following twelve hours, some 820 cubic metres of concrete were poured into the first “plot” of the seismic pit for the Tokamak complex. A total of fifteen plots will be poured over the next six months to complete the 1.5 metres thick B2 slab. In all, 15,000 cubic metres of concrete and 4000 tonnes of reinforcement will be needed for the slab.

“This is the beginning of the B2 basemat slab realization, and as I savour the moment I measure all of the work and effort that it has taken to reach this point.”

Iter Organization

The Tokamak complex will house the Iter fusion reactor as well as diagnostic and tritium management systems. It will be 120 metres long and 80 metres in height and width. This is to be supported on anti-seismic bearings which are already in place to support the 23,000 tonne mass of the reactor system.

Leader of Iter’s nuclear buildings section Laurent Patisson said, “We are all very happy and may I say relieved to have reached this important and visible milestone for the Iter project. This is the beginning of the B2 basemat slab realization, and as I savour the moment I measure all of the work and effort that it has taken to reach this point.” He added, “The concrete qualified for the B2 basemat has been the object of particular care, answering to the rigorous requirements of a nuclear facility in terms of stability, water permeability and gas confinement.”

Laurent Schmieder, head of buildings, construction and power supplies at Iter’s European domestic agency, Fusion for Energy (F4E), commented, “The coming years will be challenging because of our tight schedule and high technical requirements. Safety and nuclear security remain our two main commitments and priorities.”

The Iter project is meant to take nuclear fusion research to a new level with the largest ever Tokamak unit, which should be capable of sustaining plasmas that produce 500 MWt for as long as seven minutes. The EU is funding half of the cost while the remainder comes in equal parts from the other partners: China, Japan, India, Russia, South Korea and the USA.

After five years of gradual site preparation, construction was officially authorised in November last year. A contract, worth €500 million ($687 million), was awarded in January to a seven-company consortium called VFR for the construction of some of the buildings on the site, including the central Tokamak complex.

The facility is expected to reach full operation in 2027.

UK generates “record” amount of wind power

For the first time more than six gigawatts (GW) of power has been generated by wind in the UK.

Last Friday (29 November) between 2.30pm and 3pm, wind turbines produced an average of 6,004 megawatts (MW), making up 13.5% of the UK’s total electricity demand at that time, according to National Grid statistics.

That’s enough to power more than 3,410,000 British homes, said trade body RenewableUK.

Pakistan to build six nuclear power plants

Pakistan to build six nuclear power plants


Pakistan Prime Minister Nawaz Sharif announced Tuesday that his country will build six civil nuclear power plants.

Speaking at a function, Coastal Power Project K-II and K-III in Karachi, Sharif said the country’s Atomic Energy Commission has identified six sites where civil nuclear power plants could be built, The News International reported.

According to the prime minister, Pakistan would produce 40,000 MW of power from nuclear plants till 2050 and the government’s priority was to start work on power projects to overcome the energy shortage.

Sharif on Tuesday launched the construction of the country’s biggest atomic power plant and vowed to pursue further projects to make nuclear the largest energy source.

The 2,200-megawatt plant is to be built with Chinese technical assistance on the Arabian Sea coast at Paradise Beach, 40 km (25 miles) west of Karachi.

Pakistan already has three operational nuclear plants generating a total of around 740 MW of power and has begun work on a fourth, in addition to the one launched Tuesday.

The government hopes nuclear will ultimately provide a relatively low-cost solution to the power cuts — known euphemistically as “load-shedding” — that blight life in Pakistan.

Mismanagement, corruption and an over-reliance on expensive imported fuels have left the energy sector in dire straits, with hours-long blackouts a daily reality in the summer months.

“This is one of the first steps of our goal of racing toward a load-shedding-free Pakistan,” Sharif told the audience at the site of the plant.

The World Nuclear Association has estimated the cost of the new project at nearly $10 billion.

Pakistan Atomic Energy Commission engineers will work on the project with help from the China Atomic Energy Authority.

As Pakistan is not party to the Nuclear Non-Proliferation Treaty it is excluded from the international trade in nuclear materials and technology, and can rely only on its neighbor China for help.

Sharif pledged to increase nuclear power generation capacity to 40,000 MW in the long term as part of his energy plan.

A few kilometers further west of the new nuclear power project, an energy park is being built at Gaddani beach in Baluchistan province, with plans for 6,600 MW coal-fired power projects.

F4E said the contract, signed with a consortium comprising Cofely Axima, Cofely Ineo and Cofely Endel of France’s GDF Suez Group plc and the M+W Group LLC of Germany, is worth approximately 530 million euros (EUR) (728 million US dollars).

The contract is expected to run for six years and covers the design, supply, installation and commissioning of the ventilation, air conditioning and electrical equipment for the tokamak building complex, where the ITER machine will be located. The complex consists of the tokamak, diagnostic and tritium buildings, plus surrounding buildings.

F4E announced last week that it had signed an engineering integrator contract with ASG Superconductors of Italy for ITER’s poloidal field coils. That contract was worth approximately EUR 27.5 million.

The component – weighing several hundred tonnes – was despatched from Areva’s Saint Marcel manufacturing plant in eastern France in early September. It was transported by ship to the manufacturing site on the northwestern coast of the country, where it arrived today.The reactor vessel required 50,000 hours of design and manufacturing work, including welding, machining and assembly, Areva noted.The company said that delivery of the reactor vessel “marks the ramp-up of operations in the nuclear island and acceleration of electromechanical installation work at the site.” The vessel will be installed within the reactor building of Flamanville 3 over the coming months.

Following the placement of the dome atop the reactor building of Flamanville 3 in mid-July, civil engineering work at the unit is now 95% complete.

EDF’s director for the Flamanville EPR site Antoine Ménager commented, “Following the installation of the dome this summer, the activities on the EPR construction site continue to move forward with the arrival of the reactor vessel. The next step will be the installation of the vessel in the reactor building and the start of work for the assembly of the reactor coolant system.”

Construction work began on the 1650 MWe unit, adjacent to two existing pressurized water reactors, at the Normandy site in December 2007. EDF is architect engineer of the project, while Areva is contributing the nuclear steam supply system and Bouygues Construction is leading the civil engineering consortium. The reactor was originally expected to start commercial operation in 2013, but due to delays is now expected to start up in 2016.

EPRs are also under construction at Olkiluoto 3 in Finland and Taishan 1 and 2 in China. Olkiluoto 3 has been under construction since 2005 and has seen several revisions to its start-up date, which is now expected by 2016. Taishan 1, which has been under construction since 2009, is expected to start up in 2014, while Taishan 2 is scheduled to begin operating a year later.
