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.

世界各地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上升。以安全、成本效益高、安全和使用低碳技术的方式满足这一日益增长的能源需求是一项国际优先事项。由于核能是低碳能源，它将继续成为国际能源组合的重要组成部分。今天，14个国家正在建造大约60座核电站，计划建造的核电站超过150座，拟建的核电站还有340座。英国政府强调了英国对安全能源供应的承诺，并制定了到2050年将碳排放减少80%的雄心勃勃的目标。因此，新的核电站将在输送我们未来的能源方面起到至关重要的作用，而且已经准备好在全国各地建造12个新的核反应堆。一些专家认为，为了满足我们的能源需求和我们的碳排放目标，将需要更多的低碳核能。随着世界各地核电站数量的增加，英国公司有机会制造反应堆系统的部件，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，并与世界各地的其他公司进行商业竞争，需要研究开发更快、更便宜的方法来制造仍然具有最高质量并可在核电站使用长达60年的核部件。新核制造(NNUMAN)计划将进行研究，推动开发新的核部件和燃料制造方法，使英国制造公司能够与国际公司竞争制造业务。NNUMAN的主要目标是通过以下方式对用于核部件和燃料的制造工艺进行重大改进：1.创造新的连接部件的方法。这将发展基于传统弧焊、激光和固态(摩擦)方法的连接方法。这些设计将结合计算机建模和针对部件和燃料的实验来设计。使用可提高精度的室内全球定位系统(GPS)、可加速加工的激光，以及可同时加工大型零部件不同部件的小型可移动机器人和主轴，来提高大型和重型零部件加工的实用性。推广使用可减少制造部件所需能量的工艺，例如在模具中高温高压下将粉末熔化在一起，或通过仔细沉积熔化金属层来创建复杂的形状，而不需要更少的加工。发展对制造路线如何影响部件或燃料在核反应堆寿命期间的行为方式的理解。这一点很重要，因为制造方法会影响性能。这种新的理解将被用来确保制造的部件质量高，以便核反应堆能够有效地运行多年。在NNUMAN开发的最先进的制造工艺将在核先进制造研究中心(www.namrc.co.uk)和国家核实验室(www.nnl.co.uk)进行原型开发，以便英国制造公司能够了解新方法的好处并在未来使用它们。这将有助于企业以具有成本效益的方式制造高质量的核部件和燃料，从而赢得制造业务。
