【世界核新闻网WNN】中国致力于推进高温气冷堆的技术创新

日期:2017年9月28日 08:51

在国际原子能机构(IAEA)2017年9月19日召开的大会上,清华控股成员企业中核能源科技有限公司总经理吴郁龙表示,中国正在快速地采取行动,核能将会被用以作为重要的工业热源和燃煤替代产品。

中国的高温气冷堆示范工程(HTR-PM)开工近五年来,绝大多数研发性设备和材?#31995;?#35797;验验证工作均已完成,反应堆压力容器、不含燃?#31995;?#30707;墨球已在工程现场安装完成。HTR-PM项目的设?#21697;?#26696;是用两座分别为热功率250 MW、以氦气作为冷却剂的球床反应堆,推动一台发电功率210MW的汽轮机发电。通过这?#29615;?#26696;,它还可以灵活调整电和热的比率。

高温气冷堆的用途广泛,它可直接替代燃煤电厂用来发电,同时它产生的高温热能,可用于海水淡化、制氢或其他需要高温工艺热的工业领域。

吴郁龙说,在中国山东石?#21644;?#24314;设现场,反应堆压力容器、蒸汽发生器等设备正在陆续进行安装。目前还有待完成的工作包括蒸汽发生器最后阶段的调试等,这一工作也将在明年4月份前后完成。蒸汽发生器用于将氦气冷却剂的热?#23380;?#25442;成为高温蒸汽。

国际原子能机构负责核能事务的副总干事Mikhail Chudakov在开幕会上说:“中国HTR-PM项目的成功,将会在核能行业树立一个重要的里程碑,它将为其他国家发展和应用高温堆技术铺平道路。”

除了HTR-PM,中国已经提出了更大规模的60万千瓦高温气冷堆(HTR-PM600)。HTR-PM600相当于是6台HTR-PM的反应堆模块推动一台发电功率650MW的汽轮机。中国浙江三门、江西瑞金、福建?#35745;?#21644;万安、广东百安等HTR-PM600项目?#30446;?#34892;性研究工作已经在推进之中。

核能是中国和?#31243;?#21452;边合作的一个重点议题。?#31243;?#24076;望利用核能来发电和海水淡化。两国今年3月签订了合作协议,根据协议,中国核工业建设集团和?#31243;?#26680;能及可再生能源城将共同开展高温气冷堆项目的投资和建设,双方还将共同推动在知识产权和?#31243;?#20135;业链培育方面的合作。这一项目?#30446;?#34892;性研究成果,对?#31243;?#25919;府决定建设其他潜在的高温堆项目,也有着重要的参?#25216;?#20540;。

中国核工业建设集团透露,自双方签订合作备忘录以来,中国、?#31243;?#21452;方已经围绕选择项目厂址、建立监管制?#21462;?#36827;行人员培训等,开展了大量富有成效的工作。

China plans further high temperature reactor innovation

China is moving rapidly towards using nuclear power as an industrial heat source and as a direct replacement for coal, Yulong Wu, CEO of Chinergy, told a side event at the International Atomic Energy Agency's (IAEA's) General Conference today.

Five years into the HTR-PM program, technical tests of most innovative components and materials are complete, and on-site the reactor vessel and some non-fuel graphite spheres are loaded. The design sees two pebble-bed reactors cooled by helium produce 250 MWt MWt each and drive one steam turbine to produce 210 MWe net. It can be configured for varying ratios of electricity and heat.

Applications for HTR-PM include direct replacement of coal-fired power plants, while its heat could be used for desalination of seawater for human consumption, production of hydrogen, or a wide range of other high temperature heat applications in industry.

At the construction site in Shidaowan, in Shandong province, the steam generators and reactor vessel are in final installation, said Wu. Outstanding work includes final testing of the steam generator which transfers heat from helium coolant to a water/steam loop. Wu said these should be complete by next April. 

Opening the session, Mikhail Chudakov, IAEA deputy director general for nuclear energy, said: "The success of this project will establish a milestone for the nuclear industry. It will pave the way for others."

Beyond HTR-PM, China proposes a scaled-up version called HTR-PM600, which sees one large turbine rated at 650 MWe driven by some six HTR-PM reactor units.

Feasibility studies on HTR-PM600 deployment are underway for Sanmen, Zhejiang province, Ruijin, Jiangxi province, Xiapu and Wan'an, in Fujian province, and Bai'an, Guangdong province.

The reactor concept is a focus for cooperation between China and Saudi Arabia, which would like to use nuclear energy for electricity and production of drinking water through desalination. The countries signed a cooperation agreement in March under which China Nuclear Energy Engineering Group (CNEC) and the King Abdullah City for Atomic and Renewable Energy (KA-CARE) are to consider the development of system solutions for the investment and construction of high temperature reactors. They will also examine cooperation in intellectual property and the development of an industrial supply chain in Saudi Arabia. The feasibility study, it said, will also support the Saudi government in its decisions related to a potential high temperature reactor project.

CNEC said that since the signing of that MOU, the two countries have been looking at site selection for the project, building a regulatory system, and training personnel, among other things.
