上世纪中期到七八十年代,国际上曾兴起过一阵快堆建设高潮,欧美的快堆几乎都是在那个时代建成的。但在之后长达20年的时间里,快堆建设陷入低谷,前期建设的实验快堆也基本退役。转机出现在2000年之后,随着第四代核电技术被提出和受到广泛重视,当前,一股快堆建设的热潮正席卷全球。第四代核电技术主要包括6种堆型,分别是钠冷快堆、铅冷快堆、气冷快堆、超临界水堆、熔盐堆和超高温堆。其中,钠冷快堆尤其被业界看好,被称为所有堆型中的“一号种子选手”。据法国原子能与替代能源委员会预测,未来几十年,法国将
From the middle of the last century to the seventies and eighties, there was an upsurge of fast reactor construction in the world. Almost all the fast reactors in Europe and the United States were completed in that era. However, in the 20 years since then, the construction of fast reactors has plunged into the bottom and the pre-construction experimental fast reactor has basically been retired. The turning point appeared after 2000, with the fourth generation of nuclear power technology has been proposed and received widespread attention, at present, a surge of fast reactor construction is sweeping the globe. The fourth generation of nuclear power technology includes six reactor types, namely, sodium-cooled fast reactor, lead-cooled reactor, gas-cooled reactor, supercritical reactor, molten salt reactor and ultra-high temperature reactor. Among them, the sodium-cooled fast reactor is particularly optimistic about the industry and is called “No. 1 seed player” in all heap types. According to the French Atomic and Alternative Energy Commission forecast that France will be the next few decades
