本周最后一條，原文鏈接：http://www.sciencemag.org/content/339/6116/124.2.full.pdf Princeton, New Jersey 6 Princeton, South Korea Collaborate on Fusion Reactor 美韓合作研究核聚變反應(yīng)堆 The Princeton Plasma Physics Laboratory (PPPL), the United States’ foremost fusion lab, is to collaborate with researchers in South Korea to design a next-generation fusion power demonstration plant that could generate electricity sometime after 2030. Fusion reactors generate energy by fusing hydrogen isotopes—but no fusion reactor has yet produced more energy than required to keep it running. 普林斯頓等離子物理實(shí)驗(yàn)室（PPPL）是美國(guó)最先進(jìn)的核聚變實(shí)驗(yàn)室，它即將要和韓國(guó)的科學(xué)家合作設(shè)計(jì)下一代核聚變的示范電廠，該電廠可能將于2030年后開始啟用。核聚變反應(yīng)堆通過把氫的同位素聚合在一起產(chǎn)生能量，但是目前的反應(yīng)堆還不能產(chǎn)生出足夠的能量來維持自身的運(yùn)轉(zhuǎn)。 The United States and South Korea are partners—along with China, the European Union, India, Japan, and Russia—in ITER, an international project to build a reactor that can produce excess energy. ITER’s target is to produce 500 megawatts (MW) for 500 seconds at a time. Scientists at PPPL are preparing a work plan this month for the collaboration, which initially will run for 6 months. K-DEMO will be roughly the same size as ITER but it will produce 1000 MW and run for several weeks continuously. Rather than constructing an international demonstration reactor, many of the partners are considering building their own demonstration plants, including China, Japan, and India—and now South Korea looks set to join the race. 國(guó)際熱核聚變實(shí)驗(yàn)反應(yīng)堆（ITER）項(xiàng)目是要建造一個(gè)可以產(chǎn)生富余能量的核聚變反應(yīng)堆，該項(xiàng)目中美國(guó)和韓國(guó)是合作者，項(xiàng)目參與者還包括中國(guó)，歐盟，印度，日本和俄羅斯。ITER的目標(biāo)是要能一次性在500秒內(nèi)產(chǎn)生500兆瓦的能量。普林斯頓等離子物理實(shí)驗(yàn)室的科學(xué)家們這個(gè)月正在為雙方最開始的6個(gè)月合作起草一份工作計(jì)劃。雙方合作研發(fā)的反應(yīng)堆K-DEMO大致和ITER一樣大小，但是會(huì)產(chǎn)生1000兆瓦的能量并能連續(xù)數(shù)星期不間斷運(yùn)轉(zhuǎn)。ITER的很多合作者正在考慮建造他們自己的示范電廠，包括中國(guó)，日本和印度，而且現(xiàn)在看起來韓國(guó)也要加入這一行列。 *************************************************************** Science的原文和本翻譯僅用于網(wǎng)友交流學(xué)習(xí)之用，若您有其它用途，比如商業(yè)用途等，請(qǐng)聯(lián)系Science雜志社了解原文使用權(quán)等相關(guān)事宜。謝謝！ |
