生产氚的加速器概念并不新鲜，并且具有吸引人的特点。资本成本低于建造核反应堆生产氚所需的资金成本，并且具有安全优势。此外，多年来加速器技术的先进水平不断提高，加速器性能越来越接近该应用所需的性能。尽管如此，ERAB在报告中表示，该技术“还不够成熟，无法在未来十到十二年内提供新的生产能力”。 ERAB 的立场是基于我担任主席的 ERAB 小组的评估。小组评估认为需要进一步开发工程和技术，但并不反对这一概念本身。有两个领域需要进一步开发。首先是加速器的性能。能够以 1 至 20 亿电子伏的束能量和 200 至 300 毫安的束电流在近稳态下运行的加速器尚未建成。在基于该技术启动生产设施之前，需要对这种性能水平进行一些演示。
The accelerator concept to produce triti-um is not new and has attractive features. The capital costs are less than those required to build a nuclear reactor to produce tritium, and there are safety advantages. Moreover, the state of the art in accelerator technology has improved over the years so that accelerator performance is getting ever closer to that required for this application. Nevertheless, ERAB stated in its report that the technology is" not mature enough to provide new productioncapacity in the next ten to twelve years." The position of ERAB was based on an assessment by an ERAB panel, which I chaired. The panel evaluation identified a need for further development of the engineering and technology and was not an objection to the concept itself. There are two areas where additional development is needed. The first is the performance ofthe accelerator. Accelerators that can operateat near steady state withbeam energies of 1 to 2 billion electron volts and at beam currents of 200 to 300 milliamperes have not been built. Some demonstration of this level of performance is needed before a production facility couldbe initiated on the basis ofthis technology.
