Artist´s view of civil engineering and construction sectors to affordably realise modular design benefits. to other major infrastructure programmes in the UK over the coming years. Companies in these sectors will be able to amortise infrastructure and capability investment over multiple projects. The result will be significant cost and delivery improvements to a raft of broader UK infrastructure programmes such as High-Speed Rail, increased airport capacity, house building and urban regeneration. Nuclear plants contain many high value components that are fabricated using a range of complex technical processes. According to research carried out by the Nuclear Industry Association (NIA), in theory the UK supply chain has the capability to manufacture nearly all of the components for the large new build nuclear programme, with the main constraint being the capability to manufacture the largest components (NIA, 2012)15. In practice however, capacity is a pressing issue given that the 30-year hiatus between the construction of Sizewell B in the late 1980s and the present day new build programme has eroded much of the UK’s nuclear industry experience. Fleet deployment of a UK SMR design would provide significant confidence to the UK nuclear supply chain, allowing for the rapid development of capacity to meet the needs of an SMR programme. In turn, this new manu facturing capacity could be enhanced by the latest in manufacturing technology already being developed by world-leading researchers in the UK – notable examples being the High-Value Manufacturing (HVM) Catapult centres like the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) and the Advanced Forming Research Centre (AFRC) and the Manufacturing Technology Centre (MTC). Possible timings For a first power station the consortium envisages a seven-year period for proving the manufacturing and construction sequence of civil works and then assembly. Lessons learned would then be applied to standardised processes from then on with vision of reducing time and costs overall, following a lean manufacturing approach. The UK designed an SMR during the late 1980s and early 1990s so the concept for a small output reactor is not new. However, large reactors have remained central to baseload in many markets, including the UK. Climate change imperatives have come into play since then too, particularly driving wind and solar, while reducing fossil fuels. Fact: Who is in the consortium led by Rolls-Royce The consortium brings together the most respected and innovative engineering organisations in the world and blend them with Rolls- Royce nuclear knowledge. Rolls-Royce has a global pedigree of more than 50 years in the nuclear industry as technical authority and nuclear reactor plant designer. It’s also the supplier of safety-critical nuclear products, systems and through-life services to almost half the world’s nuclear reactors. Rolls-Royce, ARUP, Laing O’Rourke, Nuvia Wood, SNC Lavalin; BAM; Assystem; Na tional Nuclear Laboratory, Nuclear Advanced Manufacturing Research Centre, Siemens; all have a successful track record of delivering large-scale, complex engineering and infrastructure programmes. Rolls-Royce already has 32 patents and patent applications on SMR technology, and has decades of design, manufacture, delivery and operations experience. Using this already-proven technology and nuclear capability, we are developing a modular concept for nuclear technology that can be installed and commissioned quickly on site because it will be factory built and tested. Adoption of our modular approach will reduce cost and project risk by being faster to build. It will be a new way to generate electricity that will be available to the world. A design for life Overall the power station design offers a series of cost benefits in terms of the achievable LCoE: reduced financing, off-site modular construction using standard components and advanced manufacturing and imple mentation of digital through-life management. It is not just a reactor technology programme, the consortium has applied its broad nuclear and nonnuclear skills to drive modularisation and standardisation across the whole power plant. The entire design philosophy for this power station is driven to deliver electricity at the lowest cost, with modularisation and standardisation being applied to every aspect of the design, from how it can be licensed, manu factured, constructed, operated, maintained and decommissioned. It’s a design for life.

atw Vol. 64 (2019) | Issue 6/7 ı June/July Akademik Lomonosov: Pending Countdown Roman Martinek The world’s only floating nuclear power plant (FNPP) is ready for operation. In April, this information was confirmed by Rosatom, which is responsible for the Akademik Lomonosov project. Thus, the final stage of preparations is underway now – which means that very soon the world will witness operating nuclear reactors on a floating platform – something not seen for over 40 years that followed the shutdown of the US FNPP Sturgis. | | The “Akademik Lomonosov” leaves St. Petersburg under tow. Just over a year ago, the Russian Arctic port of Murmansk welcomed the Akademik Lomonosov, the floating nuclear power unit (FPU). The ship that has no propulsion system of its own was towed from the Baltic Shipyard in St. Petersburg, where it had been built, over 4,000 km through the waters of four seas – the Baltic Sea, the North Sea, the Norwegian Sea and the Barents Sea. Since then, the project has passed a number of key milestones, now inching the commercial start-up. In late April, Rosenergoatom (Electric Power Division of Rosatom State Corporation) announced the successful completion of integrated tests of the nuclear power facility. The tests’ main goal was to verify that the facility achieved the technological parameters stipulated in the floating power unit’s design and make sure that it is fully ready for operation. Shortly before, on March 31, both FPU’s reactors were brought up to 100 % capacity confirming the operational stability of the main and auxiliary equipment of the FPU, as well as the automatic process control systems. “Completing the trials successfully is a huge accomplishment for the big team of specialists at Rosatom”, commented on the occasion Rosenergoatom’s CEO Andrey Petrov. He also explained that the results of all trials will be reported in the floating power unit acceptance certificate of the governmental commission stating that the unit is ready for operation, a license is scheduled for July. The FPU is planned to be towed to the port of Pevek in North-East Russia (on the Chukchi Peninsula) during the 2019 summer shipping, where it will operate as part of a floating nuclear power plant, replacing the outgoing capacities of the Bilibino NPP and the Chaunskaya CHPP. It is expected to be connected to the power grid in December 2019. By that time, onshore and hydraulic structures for the FNPP, as well as infrastructure ensuring the transmission of electricity to the local grid and heating for the city’s network, are scheduled to be completed in Pevek. Current engineering works are running to plan, according to Rosatom. The Akademik Lomonosov is the pioneer project in the series of mobile transportable small-capacity power units (20870). This floating unit represents the new class of power sources based on Russian nuclear shipbuilding technology. It is designed for operation in the areas of the Extreme North and the Russian Far East, its main task being to provide remote industrial plants, port cities, as well as offshore gas and oil platforms with electric energy. Rosatom actively supports the idea of deploying floating power units in other Arctic subregions as well to replace diesel generation and facilitate resources development on the shelf. The Akademik Lomonosov is one of the key projects on this track – the company is also developing the second generation of FNPPs – an optimized floating power unit (OFPU) that will be smaller in size and at the same time more powerful than its predecessor – it is supposed to have two RITM-200M reactors with a capacity of 50 MW each. At present, Rosatom is negotiating with polar regions to probe local demand. In its turn, the Akademik Lomonosov is equipped with two KLT-40S reactor units that are capable of generating up to 70 MW of electric energy and 50 Gcal/h of heat energy in the normal operation mode – which is enough to maintain the activity of a town with a population of 100,000 people. Furthermore, the unit can also be converted into a desalination plant. The innovative Russian concept has already aroused interest among quite a number of foreign partners including, for instance, island states in South- East Asia and in the Middle East. | | Docking of the Floating Power Unit Akademik Lomonosov in Murmansk. Prof. Thomas Walter Tromm, who heads the Nuclear Waste Management, Safety and Radiation Research Program (NUSAFE) at the Karlsruhe Institute of Technology (KIT) Energy Centre, notes the high export potential of small modular reactors.
