EBManPower - Cost effective fabrication of Nuclear Micro-Reactors

“全球79%的电力是通过热过程产生的，其中常规发电厂提供了全球62%以上的电力供应，剩下的17%是通过核聚变过程产生的，这一数字预计还会增加(IEA，2015)。火电厂主回路的许多部件都使用大量的厚截面(20 Mm)部件；泵和阀体、辅助系统和其他安全关键部件。此外，英国的离岸风力需求需要1000座建筑物(塔楼和基础)或每年100万吨钢材。制造成本效益高。**_发电行业对‘厚截面’钢结构的需求强劲且不断增长。_**制造这些厚截面结构的能力(部分)受到焊接时间和相关成本的限制；生产一个典型的40米长(60毫米厚)的单柱需要大约6000小时的‘弧焊’时间。**_为了降低成本，这一制造时间需要显著减少。_**Aquasium Technology开发了‘EBFlow’系统，该系统基于高生产率的电子束焊接，可以将焊接时间减少到&lt；200小时，相当于降低了85%以上的成本。**EBManPower项目将在大规模制造设施中实施和验证第一个EBFlow系统，以实现大规模发电基础设施的成本效益制造。**Cammell Laird是英国最后的重型制造造船厂之一，也是U电池微型模块反应堆(MMR)系统的制造合作伙伴。该项目将重点使用我们在伯肯黑德工厂部署的EBFlow系统，以证明以具有成本效益的方式制造MMR的可行性。实现这一目标将是推动新的、具有成本效益的核裂变解决方案的广泛部署的关键，以满足英国国内和全球的低碳能源需求。通过这个项目，我们的合作伙伴相信，我们可以增加收入，增加出口，并在制造业和低碳能源部门获得高价值的工作岗位。

"Globally 79% of electricity is generated by thermal processes, in which conventional power plants provide over 62% of global electricity supply and the remaining 17% is by nuclear fusion processes and this is expected to increase (IEA, 2015). Thermal power plants make use of a large number of thick section (\>20mm) components for many parts of the primary circuit; pump and valve bodies, ancillary systems and other safety critical components. Furthermore, off-shore wind demand in the UK requires \>1,000 structures (towers and foundations) or 1m tonnes of steel p.a. to be cost-effectively fabricated.**_The demand for 'thick section' steel structures in power generation is strong & growing._**The ability to fabricate these thick section structures cost-effectively is (in part) limited by the welding time and associated cost; to produce a typical 40m long monopile (60mm thick) takes ~6,000 hrs of 'arc-on' welding time.**_To reduce cost this manufacturing time needs to be significantly reduced._**Aquasium technology has developed the 'EBFlow' system, based on high productivity electron beam welding which can reduces this welding time to <200 hrs, equivalent to a reduction in cost of over 85%.**The EBManPower project will implement and validate the first EBFlow system within a large-scale fabrication facility to enable cost-effective manufacture of large scale power generation infrastructure.**Cammell Laird is one of the UKs last heavy fabrication ship yards and is the manufacturing partner for the U-Battery micro modular reactor (MMR) system. This project will focus on using the EBFlow system deployed at our site in Birkenhead to demonstrate the viability to fabricate MMRs in a cost-effective manner. Being able to achieve this will be critical to drive widespread deployment of new, cost-effective, nuclear fission solutions to meet low-carbon energy needs both within the UK and across the globe.Through this project our partnership believe we can increase revenues, grow exports and secure high value jobs in manufacturing and low-carbon energy sectors."
