日本土岐市，9月29日电：日本初创企业Helical Fusion周二表示，预计于2027年开始对其聚变示范反应堆进行初步通电测试。这是该公司朝着成为全球商业核聚变能源领军者目标迈出的一步。
TOKI, Japan, Sept 29 : Japanese startup Helical Fusion expects to begin preliminary power-on tests at its demonstration fusion reactor in 2027, it said on Tuesday, a step towards its goal of becoming a global leader in commercial nuclear fusion energy.
该公司正在开发Helix HARUKA，这是日本首座采用螺旋式聚变技术的一体化试验反应堆。该试验设施旨在验证稳定、连续聚变反应的可行性。
The company is developing Helix HARUKA, Japan's first integrated pilot reactor using the helical approach to fusion. The pilot facility is designed to demonstrate the feasibility of stable, continuous fusion reactions.
核聚变是指在超高温条件下使原子相互碰撞并融合，从而像太阳一样产生热量。未来，它有可能产生巨量清洁电力，同时仅产生少量放射性废物，而当今的裂变反应堆并非如此。
Nuclear fusion involves smashing atoms together at super-high temperatures to generate heat the same way the sun does. It could one day produce enormous amounts of clean power with little radioactive waste, in contrast to today's fission reactors.
尽管全球各方都在努力开发聚变能，但70年的研究仍未催生具备商业化可行性的反应堆。
Despite global efforts to harness fusion energy, 70 years of research have yet to yield a commercially viable reactor.
Helical Fusion于2025年完成高温超导（HTS）线圈的性能测试，在全球首次复现了聚变装置内部的磁场环境，并在超导条件下实现稳定电流。公司表示，这一成果扫清了制造和建造一体化示范反应堆的一道关键难关。
Helical Fusion completed a performance test of a high-temperature superconducting (HTS) coil in 2025, replicated the magnetic environment inside a fusion device and achieved a stable current flow under superconducting conditions, in a world first. The result cleared a key hurdle for manufacturing and constructing the integrated demonstration reactor, it said.
日本中部土岐市日本核聚变科学研究所（NIFS）内的首个螺旋线圈于今年年初开工建设，目前已基本完工，公司因此得以向媒体开放该设施。
Construction of the first spiral coil at the National Institute for Fusion Science (NIFS) site in Toki, central Japan, started early this year and is now largely complete, allowing the company to open the facility to the media.
Helical Fusion表示，如果第一阶段测试取得成功，公司计划在约2030年对建成的一体化设施进行通电测试之前，安装第二个线圈及其他主要部件，包括液态金属壁包层。
If the first-stage tests are successful, Helical Fusion said it planned to install a second coil and other major components, including a liquid-metal wall blanket, before conducting power-on tests of the completed integrated facility around 2030.
公司计划在HARUKA之后建设规模更大的HELIX KANATA反应堆，其净输出功率为50兆瓦，旨在验证稳定、连续的发电能力。公司计划在2030年代全面投资该项目。
The company plans to follow HARUKA with HELIX KANATA, a bigger reactor with a net power output of 50 MW, aiming to demonstrate stable and continuous power generation. It plans to begin full-scale investment in the project in the 2030s.
Helical Fusion 是全球最大的核聚变研究机构之一 NIFS 所研发的螺旋形核聚变技术的唯一私营领域继承者。该公司致力于开发世界上首座基于螺旋形设计、具备商业可行性的核聚变发电厂。
Helical Fusion is the sole private-sector inheritor of the helical fusion technology developed by NIFS, one of the world's largest fusion research facilities. It aims to develop the world's first commercially viable fusion power plant based on the helical design.
Helical Fusion 的首席执行官 Takaya Taguchi 向记者表示，公司计划在 2040 年代之前建成这座商业发电厂；不过在实现商业化运营之前，仍需克服诸多障碍——这些障碍不仅包括技术方面的问题，还包括成本、安全性和建设速度等方面的挑战。
Helical Fusion CEO Takaya Taguchi told reporters the company aims to build a commercial power plant as early as the 2040s but said before commercial operations can begin, there are various hurdles to overcome—not only technical ones, but also issues such as cost, safety and construction speed.
日本首相 Sanae Takaichi 是核聚变产业的坚定支持者。日本政府已将核聚变能列为 17 个战略性产业之一，并计划通过公共和私营部门的资金投入，在 2040 财年之前累计投入 3.1 万亿日元（约合 197 亿美元）用于核聚变技术研发。
Japanese Prime Minister Sanae Takaichi is a strong supporter of the nuclear fusion industry. The government has designated fusion energy as one of 17 strategic sectors and plans to invest 3.1 trillion yen ($19.7 billion) through public and private sector funding by the 2040 financial year.
