Abstract

Removal of silica from the borated water of primary systems of the nuclear power plant remains a long-term challenge for the industry. The same was tried to solve by membrane technology, however, membrane technology has its issues like generations of additional radioactive wastes. To address this issue a specialized hybrid resin for selective silica removal from borated water was prepared and tested for its efficiency at a pilot scale on an inventory taken from the spent fuel pool of an operational nuclear power plant having 2110 ppm boron and 400 ppb silica. The developed hybrid resin technique offers a simple and easy procedure to overcome several problems encountered in other methods of silica removal such as additional equipment, additional waste handling and maintenance. The validation shows that the application of the developed technique has a silica removal efficiency of 38% without affecting boron concentration.

使用混合树脂减少发电厂乏燃料池硼酸水二氧化硅含量的试验规模

从核电厂一级系统的硼酸盐水中去除二氧化硅仍然是该行业面临的一项长期挑战。同样的问题也曾试图通过膜技术来解决，但膜技术也有其自身的问题，比如会产生额外的放射性废物。为了解决这个问题，我们制备了一种用于从含硼水中选择性去除二氧化硅的专用混合树脂，并在试验规模上对取自运行中核电厂乏燃料池的库存（含硼 2110 ppm，二氧化硅 400 ppb）进行了效率测试。所开发的混合树脂技术提供了一个简单易行的程序，克服了其他去除二氧化硅方法所遇到的几个问题，如额外的设备、额外的废物处理和维护。验证结果表明，在不影响硼浓度的情况下，所开发技术的二氧化硅去除效率为 38%。

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
