The increase in energy needs around the world has led to a large rise in carbon dioxide emissions from burning fossil fuels. Meeting this growing energy need in a way that is safe, cost effective, secure, and uses low carbon technologies is an international priority. Because nuclear power is low carbon it will continue to be an important part of the international energy mix. Today, around 60 nuclear power stations are being built in 14 countries with more than 150 planned and a further 340 proposed. The Government has highlighted the UK's commitment to a safe and secure energy supply and has set an ambitious target of an 80% reduction in carbon emissions by 2050. New nuclear power stations will therefore have an essential role in delivering our future energy, and preparations are already in place to build 12 new nuclear reactors around the country. Some experts think that even more low carbon nuclear energy will be needed to meet both our energy demands and our carbon emissions targets. With the number of nuclear power stations increasing around the world, there is an opportunity for UK companies to manufacture parts of the reactor system, including pressure vessels, internal supporting structures and piping as well as the nuclear fuel. In order to do this safely, and to compete commercially with other companies around the world, research is needed to develop faster and cheaper ways of manufacturing nuclear components that are still of the highest quality and will last for up to 60 years in power stations.The New Nuclear Manufacturing (NNUMAN) programme will perform the research that will drive the development of new manufacturing approaches for nuclear components and fuels to UK manufacturing companies who can then compete with international companies for manufacturing business.The main aim of NNUMAN is to introduce major improvements to the manufacturing processes used for nuclear components and fuels by:1. Creating new ways to join components. This will develop joining methods that are based on traditional arc-welding, lasers and solid-state (friction) methods. These will be designed using a combination of computer modelling and experiments for both components and fuels.2. Improving the practicality of machining of large and heavy components using indoor Global Positioning Systems (GPS) that can improve accuracy, lasers that can accelerate machining, and small movable robots and spindles in a "swarm" that can simultaneously perform machining of different parts of a large components.3. Extending the use of processes that can reduce the energy needed to make components such as fusing powders together at high temperature and pressure in a mould or by carefully depositing layers of molten metal to create complicated shapes with much less need for machining.4. Developing the understanding of how the manufacturing route affects the way a component or fuel behaves during the lifetime of the nuclear reactor. This is important because manufacturing approaches affect performance. This new understanding will be used to make sure that the quality of manufactured components is high, so that nuclear reactors can operate effectively for many years.The most improved manufacturing processes developed in NNUMAN will be taken forward to prototype in the Nuclear Advanced Manufacturing Research Centre (www.namrc.co.uk) and the National Nuclear Laboratory (www.nnl.co.uk) so that the UK manufacturing companies can learn the benefits of the new methods and use them in the future. This will help companies to win manufacturing business by making high quality nuclear components and fuels in a cost-effective manner.

全球能源需求的增加导致燃烧化石燃料的二氧化碳排放量大幅增加。以安全，成本效益，安全和使用低碳技术的方式满足这种不断增长的能源需求是国际优先事项。由于核电为低碳，它将继续成为国际能源组合的重要组成部分。如今，在计划有150多个计划的14个国家 /地区建造了大约60个核电站，另有340个核电站。政府强调了英国对安全和安全的能源供应的承诺，并在2050年之前雄心勃勃的碳排放量减少了80％。因此，新的核电站将在提供我们的未来能源方面发挥重要作用，并且已经为在全国范围内建造12个新的核反应堆的准备工作已经存在。一些专家认为，还需要更低的碳核能来满足我们的能源需求和碳排放量。随着世界各地核电站的数量增加，英国公司有机会制造反应堆系统的部分，包括压力容器，内部支撑结构和管道以及核燃料。为了安全地做到这一点，要与世界其他公司进行商业竞争，需要进行研究，以开发更快，更便宜的制造方式，制造仍然处于最高质量的核部件，最多可持续60年，在电力站中，新的核制造业（NNNUMAN）计划将促进核构造公司的主要业务，以促进核构造公司的主要业务，以促进核能组成公司的发展，并能够竞争核能组成的业务。 Nnuman的涉及核部件和燃料的制造工艺的重大改进：1。创建加入组件的新方法。这将开发基于传统弧形，激光器和固态（摩擦）方法的连接方法。这些将使用计算机建模和组件和燃料实验的组合进行设计。2。使用室内全球定位系统（GPS）改善大型和重组件的实用性，这些系统（GPS）可以提高准确性，可以加速加工的激光器以及“群”中的小型移动机器人和纺锤体，这些机器人可以同时执行大型部件不同部位的加工。3。扩展可以减少将组件（例如在高温和模具中的压力融合在一起或小心地沉积熔融金属的层以产生复杂形状的复杂形状，对加工需求少得多的形状）中所需能量的能量所需的能量。4。发展对制造路线的理解会影响组件或燃料在核反应堆一生中的行为方式。这很重要，因为制造方法会影响性能。这种新的理解将用于确保制造成分的质量很高，以便核反应堆可以有效运行多年。nnuman开发的最快的制造工艺将被带到核先进制造研究中心（www.namrc.co.uk）的原型中，并将其构成工具（www.nnl.co.uk）。 未来。这将通过以具有成本效益的方式制造高质量的核零件和燃料来帮助公司赢得制造业务。
