The participants, more than half of them women, came from Africa, Asia, Europe and the Americas. Full-text documents available in the INIS repository represent almost entirely nuclear-related non-conventional literature. Non-conventional literature includes any literature which is not normally available through commercial distribution channels and which is generally difficult to locate. The depth and breadth of the INIS repository and the large number of daily users demonstrate how a well-planned and implemented international cooperation project can make a significant contribution to open science. | www.iaea.org Company News Framatome successfully implements innovative maintenance technique on reactor vessel component underwater (framatome) Framatome applied a cutting-edge maintenance technique on reactor vessel primary nozzles at Dominion Energy’s Millstone Power Station during the plant’s spring 2019 outage. This was the first application of Framatome’s ultra-high pressure (UHP) cavitation peening process on reactor pressure vessel nozzles to primary pipe welds. Because it is deployed directly to the inner surface, it is uniquely suited to remediate the component regardless of external space restrictions or dose constraints. “Framatome’s innovative solutions are ensuring the efficient and reliable operation of today’s reactor fleet,” said Catherine Cornand, Framatome’s senior executive vice president in charge of the Installed Base Business Unit. “This new underwater application of UHP cavitation peening on a primary nozzle is another example of our team’s expertise and dedication to innovation and continuous improvement in servicing our customers worldwide.” To prepare for the work, Framatome demonstrated the qualified reactor vessel primary nozzle cavitation peening technology on a full-scale mock-up at the company’s world-class Technical Training Center in Lynchburg, Virginia, in early 2019. UHP cavitation peening is designed to prevent primary water stress corrosion cracking. The process uses ultra-high-pressure water jets to generate vapor bubbles that collapse with enough force to create beneficial compression of the components’ surfaces. This surface compression improves components’ material properties and enhances resistance to corrosion and other types of degradation, which reduces the effects of aging. UHP cavitation peening can extend the life of nuclear reactor primary components, including the hot leg primary nozzles, for up to 40 additional years. Additionally, the process reduces outage time and saves money by eliminating the need to replace components or address indications with traditional repair methods. UHP cavitation peening can be used for several different applications in most reactor designs. “Cavitation peening is an industry game-changer that was recognized in 2017 as one of the Top Innovative Practices for work completed on the Byron and Braidwood reactor vessel closure heads,” said Craig Ranson, senior vice president of Framatome’s North America Installed Base Business Unit. “We are proud to work with Dominion to expand our proven capabilities and engineer a solution for this unique primary nozzle repair.” Located in Waterford, Connecticut, the Millstone Power Station’s two pressurized water reactors produce enough electricity to power 2.1 million homes. | www.framatome.com UK Government and industry champion new compact nuclear power station (rolls-royce) UK Research and Innovation (UKRI) has confirmed it has provided initial match funding to the consortium of companies designing a new type of nuclear power station in the UK. | Artist's view of the SMR design of a new UK nuclear power station project. The initial joint investment of £18million from UKRI will be matched by nuclear, civil engineering construction and manufacturing industry firms, who have been working on the preliminary design for four years. The power station is a compact design, the components for which are manufactured in sections in regional UK factories, before being transported to existing nuclear sites for rapid assembly inside a weatherproof canopy. This cuts costs by avoiding weather disruptions and secures gradual efficiency savings by using streamlined and standardised manufacturing processes for its components. By 2050 a full UK programme of up to 16 of these power stations could create: p Up to 40,000 jobs p £ 52 bn of value to the UK economy p £ 250 bn of exports Paul Stein, Chief Technology Officer for Rolls-Royce, which leads the consortium, said: “Tackling climate change requires collaboration across industries and governments to find effective, affordable and sustainable ways of achieving net zero by 2050. “The consortium’s work with the Government shows that action is being taken to decarbonise our economy and meet our society’s vital and growing power needs. This is a very positive step forward to this next phase of the programme.” The partners in the consortium are Assystem, BAM Nuttall, Laing O’Rourke, National Nuclear Laboratory (NNL), Rolls-Royce, Atkins, Wood, The Welding Institute (TWI) and Nuclear AMRC. The target cost for each station is £1.8 billion by the time five have been built, with further savings possible. Each power station will be able to operate for 60 years and provide 440 MW of electricity, which is enough to power a city the size of Leeds. News
atw Vol. 64 (2019) | Issue 11/12 ı November/December The shared initial investment will be used to progress the significant opportunities presented by the programme; prepare it for the UK’s regulatory Generic Design Assessment process; and make final decisions on which innovations to pursue and realise. It will also generate the valuable confidence that the supply chain needs to begin to prepare for a programme that could create around £52 billion of value for the UK economy. When licensed and supported by the required enabling legislation and siting processes, the power station could provide reliable low carbon energy from the early 2030s. The Government’s intent to support the programme was announced in July 2019. | www.rolls-royce.com Uranium Prize range: Spot market [USD*/lb(US) U 3O 8] 140.00 120.00 100.00 80.00 60.00 40.00 20.00 0.00 1980 Yearly average prices in real USD, base: US prices (1982 to1984) * 1985 1990 1995 2000 2005 ) 1 2010 2015 2019 Year * Actual nominal USD prices, not real prices referring to a base year.
