TaylorWilson_2013-_我的激进计划_小型核裂变反应堆_
Well, I have a big announcement to make today, and I'm really excited about this. 我今天要發表一個重大聲明 我感到很興奮
And this may be a little bit of a surprise to many of you who know my research and what I've done well. 各位可能會感到驚訝 因為很多人對我過去的研究 及成果相當瞭解
a little bit of a:一点点了;
I've really tried to solve some big problems: counterterrorism , nuclear terrorism, and health care and diagnosing and treating cancer , but I started thinking about all these problems, 我曾努力解決一些重大問題: 反恐怖主義、核子恐怖主義、 醫療保健、診斷治療癌症 但我開始思考這些問題時

and I realized that the really biggest problem we face, what all these other problems come down to, is energy, is electricity , the flow of electrons . 我意識到我們面臨的最大問題 也是所有問題的根源 就是能源,也就是電流,電子的流動
electricity:n.电力;电流;强烈的紧张情绪; electrons:n.[物]电子(electron的复数形式);
And I decided that I was going to set out to try to solve this problem. 我決定要開始 嘗試解決這個問題
And this probably is not what you're expecting. 以下可能並非各位期待的
You're probably expecting me to come up here and talk about fusion , because that's what I've done most of my life. 你們可能希望我到這裡 來談核聚變 因為那是我目前做最多的事
fusion:n.融合;熔化;熔接;融合物;[物]核聚变;
But this is actually a talk about, okay -- 但我今天真正要說的是…
(Laughter) — but this is actually a talk about fission. （笑）好… 我今天真正要說的是－核裂變
It's about perfecting something old, and bringing something old into the 21st century. 把老東西變得更完美 把老東西帶入21世紀
Let's talk a little bit about how nuclear fission works. 先簡單說明核裂變的原理
nuclear fission:n.核裂变;
In a nuclear power plant, you have a big pot of water that's under high pressure, and you have some fuel rods , and these fuel rods are encased in zirconium , 核電廠裡有個 很大的高壓水箱 及一些燃料棒 這些燃料棒,用鋯封裝了
nuclear power:na.核大国; rods:n.鱼竿(rod的复数);棒条体;v.装避雷针;用杆捅清(rod的单三形式); encased:adj.包装的;被包住的;v.盖住;包起;装箱(encase的过去分词); zirconium:n.[化学]锆;
and they're little pellets of uranium dioxide fuel, and a fission reaction is controlled and maintained at a proper level, and that reaction heats up water, the water turns to steam, steam turns the turbine , and you produce electricity from it. 小小的二氧化鈾燃料丸 核裂變反應會控制在適當水準 將水加熱 水變成蒸汽,蒸汽推動渦輪 電就產生了
pellets:n.芯块,小球(pellet的复数);靶丸;v.使形成小球(pellet的第三人称单数); uranium:n.[化学]铀; dioxide:n.二氧化物; reaction:n.反应,感应;反动,复古;反作用; maintained:v.维持;维修;保养;固执己见;(maintain的过去式和过去分词) turbine:n.汽轮机;涡轮机;
This is the same way we've been producing electricity, the steam turbine idea, for 100 years, and nuclear was a really big advancement in a way to heat the water, but you still boil water and that turns to steam and turns the turbine. 我們一直採用相同方式發電 蒸汽渦輪已用了100年 以加熱水的方法而言 核能真是巨大的進步 但還是要燒水,變成蒸汽推動渦輪
advancement:n.前进,进步;提升;
And I thought, you know, is this the best way to do it? 我想,這是最好的方式嗎？
Is fission kind of played out , or is there something left to innovate here? 核裂變是不是落伍了 還是可以繼續創新呢？
played out:adj.失去影响(或作用); innovate:vi.创新;改革;革新;vt.改变;创立;创始;引人;
And I realized that I had hit upon something that I think has this huge potential to change the world. 我意識到一個想法 有巨大的潛力可以改變世界
potential:n.潜能;可能性;[电]电势;adj.潜在的;可能的;势的;
And this is what it is. 這個想法是這樣的
This is a small modular reactor . 這是個小型模組化反應爐
modular:adj.模块化的;模数的;有标准组件的; reactor:n.[化工]反应器;[核]反应堆;起反应的人;
So it's not as big as the reactor you see in the diagram here. 不像那張圖裡的反應爐那麼大
This is between 50 and 100 megawatts . 介於50到100百萬瓦
megawatts:n.百万瓦特(megawatt的复数);
But that's a ton of power. 但仍是很大的功率
That's between, say at an average use, that's maybe 25,000 to 100,000 homes could run off that. 在一般情況下 可供2萬5千至10萬個家庭使用
Now the really interesting thing about these reactors is they're built in a factory. 這些反應爐真正有趣的地方在於 是工廠生產出來的
reactors:n.[化工]反应器(reactor的复数);反应者;
So they're modular reactors that are built essentially on an assembly line , and they're trucked anywhere in the world, you plop them down, and they produce electricity. 模組化反應爐 是在生產線上建造出來的 然後運到世界各地 丟著就可以發電了
essentially:adv.本质上;本来; assembly line:na.装配线; plop:n.扑通声; v.把…沉重地放下; v.扑通一声地;
This region right here is the reactor. 這個區域就是反應爐
region:n.地区;范围;部位;
And this is buried below ground, which is really important. 是埋在地底下的,這很重要
For someone who's done a lot of counterterrorism work, 對從事反恐工作的人來說
I can't extol to you how great having something buried below the ground is for proliferation and security concerns . 我的言語難以形容 埋在地下有多美好 因為沒有核子擴散和安全問題
extol:vt.颂扬;赞美;赞颂; proliferation:n.增殖,扩散;分芽繁殖; concerns:n.关注; v.使关心(concern的三单形式);
And inside this reactor is a molten salt, so anybody who's a fan of thorium , they're going to be really excited about this, because these reactors happen to be really good at breeding and burning the thorium fuel cycle, uranium-233. 反應爐裡面是熔解的鹽 在座如果有釷元素的粉絲 一定會很興奮 因為這種反應爐最擅長 釷燃料循環的滋生和燃燒 最後產生鈾-233
molten:adj.熔化的;铸造的;炽热的;v.换毛;脱毛(molt的过去分词); thorium:n.[化学]钍(放射性金属元素,元素符号Th,原子序数为90); breeding:n.繁殖;饲养;教养;再生;v.生产;培育;使…繁殖;(breed的现在分词)
But I'm not really concerned about the fuel. 我真正關心的不是燃料
concerned:adj.有关的;关心的;v.关心;与…有关;(concern的过去时和过去分词)
You can run these off -- they're really hungry, they really like down-blended weapons pits , so that's highly enriched uranium and weapons-grade plutonium that's been down-blended. 因為總會用完的,反應爐很餓 反應爐很喜歡稀釋的核武原料 像高濃縮鈾和及核武級的鈽 加以稀釋
pits:n.维修区(pit的复数); v.除去…的核; highly:adv.高度地;非常;非常赞许地; enriched:v.使丰富;使饱含(某物);使富有;(enrich的过去分词和过去式) weapons-grade:武器级的; plutonium:n.[化学]钚(94号元素);
It's made into a grade where it's not usable for a nuclear weapon, but they love this stuff . 降到不可能用來作為核武 模組化反應爐很愛吃這個
stuff:n.东西:物品:基本特征:v.填满:装满:标本:
And we have a lot of it sitting around, because this is a big problem. 而我國有一大堆 這是個大問題
You know, in the Cold War, we built up this huge arsenal of nuclear weapons, and that was great, and we don't need them anymore, and what are we doing with all the waste, essentially? 冷戰時期我們儲備了 大量的核武,太棒了 我們再也不需要核武了 這些留下來的垃圾該怎麼辦？
arsenal:n.兵工厂;军械库;
What are we doing with all the pits of those nuclear weapons? 核武裡的核物質要怎麼處理？
Well, we're securing them, and it would be great if we could burn them, eat them up, and this reactor loves this stuff. 我們要確保其安全 如果能燒掉、吃掉,那就太棒了 這個反應爐就愛這樣
So it's a molten salt reactor. It has a core , and it has a heat exchanger from the hot salt, the radioactive salt, to a cold salt which isn't radioactive. 熔鹽反應爐有個核心 還有熱交換器,把熱量由 「熱鹽」,即放射性鹽傳到「冷鹽」,即無放射性的鹽
core:n.核心;要点;果心;[计]磁心;vt.挖...的核; heat exchanger:n.热交换器; radioactive:adj.[核]放射性的;有辐射的;
It's still thermally hot but it's not radioactive. 冷鹽還是很熱,但沒有放射性
thermally:adv.热地;用热的方法;
And then that's a heat exchanger to what makes this design really, really interesting, and that's a heat exchanger to a gas. 熱交換器 是這種反應爐設計最有趣的地方 這種熱交換器用的是氣體
So going back to what I was saying before about all power being produced -- well, other than photovoltaic -- being produced by this boiling of steam and turning a turbine, that's actually not that efficient , and in fact, in a nuclear power plant like this, it's only roughly 30 to 35 percent efficient. 我剛說了,產生所有的能量前 除了光電池外… 都要燒水,產生蒸汽,推動渦輪 如此效率並不高,事實上 傳統的核電廠 效率大約只有30到35%
photovoltaic:adj.[电子]光电伏打的,光电的; efficient:adj.有效率的;有能力的;生效的; power plant:n.发电厂;发电站; roughly:adv.粗糙地;概略地;
That's how much thermal energy the reactor's putting out to how much electricity it's producing. 這是反應爐產生的熱能 與實際產生電力的比值
And the reason the efficiencies are so low is these reactors operate at pretty low temperature. 效率這麼低的原因是這些反應爐 在低溫下運轉
efficiencies:n.效率(efficiency的复数);
They operate anywhere from, you know, maybe 200 to 300 degrees Celsius . 運轉溫度介於 約攝氏200到300度
Celsius:adj.摄氏的;n.摄氏度;
And these reactors run at 600 to 700 degrees Celsius, which means the higher the temperature you go to, thermodynamics tells you that you will have higher efficiencies. 新型反應爐高達攝氏600到700度 溫度越高 依據熱力學原理,效率就越高
thermodynamics:n.热力学;
And this reactor doesn't use water. It uses gas, so supercritical CO2 or helium , and that goes into a turbine, and this is called the Brayton cycle. 而且這個反應爐不用水,改用氣體 用超臨界二氧化碳,或是氦氣 氣體直接進入渦輪 稱為布雷頓循環
supercritical:adj.[物][物化]超临界的;吹毛求疵的; helium:n.[化学]氦(符号为He,2号元素);
This is the thermodynamic cycle that produces electricity, and this makes this almost 50 percent efficient, between 45 and 50 percent efficiency . 是個產生電的熱力學循環 效率接近50% 在45%到50%之間
efficiency:n.效率;效能;功效;
And I'm really excited about this, because it's a very compact core. 我真的感到很興奮 因為這個核心相當小
compact:n.合同,契约;小粉盒;adj.紧凑的,紧密的;简洁的;vt.使简洁;使紧密结合;
Molten salt reactors are very compact by nature, but what's also great is you get a lot more electricity out for how much uranium you're fissioning, not to mention the fact that these burn up. 熔鹽反應爐本來就很小 另外也很棒的,是會得到更多的電 比等量的鈾分裂還多 更不用提燃耗了
not to mention:更不必说;不必提及;
Their burn-up is much higher. 新反應爐的燃耗比率高多了
So for a given amount of fuel you put in the reactor, a lot more of it's being used. 放進等量的燃料 利用到的多了很多
And the problem with a traditional nuclear power plant like this is, you've got these rods that are clad in zirconium, and inside them are uranium dioxide fuel pellets. 傳統的核電廠有個問題 燃料棒用鋯包著 裡面是二氧化鈾燃料丸
traditional:传统的,惯例的, clad:adj.穿衣的; vt.在金属外覆以另一种金属; v.穿衣(clothe的过去式和过去分词);
Well, uranium dioxide's a ceramic , and ceramic doesn't like releasing what's inside of it. 二氧化鈾已燒結為陶瓷 陶瓷不太會釋出內部的東西
ceramic:adj.陶瓷的;陶器的;制陶艺术的;n.陶瓷;陶瓷制品; releasing:n.释放;松释动作;脱扣释放;v.释放;排放;(release的现在分词);
So you have what's called the xenon pit, and so some of these fission products love neutrons . 氙氣會累積 有些核裂變產物很喜歡中子
xenon:n.[化学]氙(稀有气体元素); neutrons:n.[核]中子(neutron的复数);
They love the neutrons that are going on and helping this reaction take place . 很喜歡周圍這些中子 並幫助反應進行
take place:发生;举行;
And they eat them up, which means that, combined with the fact that the cladding doesn't last very long, you can only run one of these reactors for roughly, say, 18 months without refueling it. 會將其侵蝕掉,再加上 包覆層不太耐用 所以傳統反應爐 補充燃料一次大約只可燒18個月
cladding:n.包层;电镀;喷镀;v.穿衣(clad的ing形式); refueling:n.再加燃料;再加油;v.给…再加燃料(refuel的ing形式);
So these reactors run for 30 years without refueling, which is, in my opinion , very, very amazing, because it means it's a sealed system. 新式核反應爐可用30年不用補充燃料 我覺得非常非常驚人 因為這意味著一個全封閉的系統
in my opinion:在我看来;我认为;
No refueling means you can seal them up and they're not going to be a proliferation risk, and they're not going to have either nuclear material or radiological material proliferated from their cores . 不用補充燃料表示可以封起來 就不會有核子擴散的風險了 不會有… 核子物質或放射性物質 從內核洩漏出來
radiological:adj.放射学的;放射线学的; proliferated:vi.增殖;扩散;激增;vt.使激增; cores:n.[晶体]核心; v.挖去(水果的)果心(core的第三人称单数);
But let's go back to safety, because everybody after Fukushima had to reassess the safety of nuclear, and one of the things when I set out to design a power reactor was it had to be passively and intrinsically safe, and I'm really excited about this reactor for essentially two reasons. 再回到安全問題 福島事故後,大家都重新評估核能安全 我開始設計新型反應爐的理念之一 就是必須為被動安全和本質安全 我對新型反應爐感到很興奮 有兩個重要原因:
reassess:vt.再评价;再课税;再摊派; passively:adv.被动地;顺从地; intrinsically:adv.本质地;内在地;固有地;
One, it doesn't operate at high pressure. 第一,不必在高壓環境中運轉
So traditional reactors like a pressurized water reactor or boiling water reactor, they're very, very hot water at very high pressures, and this means, essentially, 傳統反應爐,如壓水式反應爐 或沸水式反應爐 都有高熱高壓的水,這表示
pressurized:adj.加压的; v.逼迫; (pressurize的过去式和过去分词)
in the event of an accident, if you had any kind of breach of this stainless steel pressure vessel , the coolant would leave the core. 一旦發生事故 當不銹鋼壓力容器出現裂縫 冷卻劑就會從內核中洩漏出來
breach:n.违背;破坏;辜负;中断;v.违反;违背;在…上打开缺口; stainless steel:n.不锈钢; vessel:n.器皿;轮船;脉管;大船; coolant:n.冷却剂;
These reactors operate at essentially atmospheric pressure, so there's no inclination for the fission products to leave the reactor in the event of an accident. 新型反應爐在一般大氣壓力下運轉 核裂變產物不太可能 會在事故中洩漏
atmospheric:adj.大气的,大气层的; inclination:n.倾向;意愿;趋向;趋势;倾斜度;
Also, they operate at high temperatures, and the fuel is molten, so they can't melt down, but in the event that the reactor ever went out of tolerances , or you lost off-site power in the case of something like Fukushima, there's a dump tank. 而且反應爐在高溫運轉 燃料本就是熔化的,所以不會熔毀 即使這個反應爐真的撐不住了 或像福島那樣失去外部電源 我們還有排汙槽
melt:v.融化;(使)软化; tolerances:n.界值,容差(tolerance的复数);v.给…定公差(tolerance的第三人称单数); off-site:n.工地外;厂区外; dump:v.倾倒;抛售;抛弃;转存;n.垃圾场;转储;转存;废物堆;
Because your fuel is liquid, and it's combined with your coolant, you could actually just drain the core into what's called a sub-critical setting, basically a tank underneath the reactor that has some neutrons absorbers . 因為燃料是液體,混合了冷卻劑 事實上可把整個內核 排入亞臨界裝置 基本上就是反應爐下的水槽 裡面有中子吸收劑
drain:v.排水;流干;喝光,耗尽;n.排水;下水道,排水管;消耗; basically:adv.主要地,基本上; underneath:prep.在…的下面;在…的支配下;n.下面;底部;adj.下面的;底层的; absorbers:[化工][电子]吸收器; (核反应堆中吸收中子的)吸收料(absorber的复数);
And this is really important, because the reaction stops. 這很重要,因為連鎖反應停止了
In this kind of reactor, you can't do that. 傳統反應爐無法做到這點
The fuel, like I said, is ceramic inside zirconium fuel rods, and in the event of an accident in one of these type of reactors, 它的燃料是包在鋯燃料棒裡的陶瓷 以下幾種反應爐如果發生事故
Fukushima and Three Mile Island -- looking back at Three Mile Island, we didn't really see this for a while — but these zirconium claddings on these fuel rods, 例如福島和三哩島… 回顧三哩島,我們好久沒關心了… 燃料棒外面的鋯包覆
for a while:adv.片刻;暂时;一会儿;一时;
what happens is, when they see high pressure water, steam, in an oxidizing environment, they'll actually produce hydrogen , and that hydrogen has this explosive capability to release fission products. 遇到高壓的水 或蒸汽,並處在氧化環境中 實際上會產生氫氣 氫氣有可能爆炸 釋放核裂變產物
oxidizing:adj.氧化的;氧化作用;v.使氧化(oxidize的ing形式); hydrogen:n.氢;氢气; explosive:n.炸药;爆炸物;adj.易爆炸的;可能引起爆炸的;易爆发的;可能引起冲动的; capability:n.才能,能力;性能,容量;
So the core of this reactor, since it's not under pressure and it doesn't have this chemical reactivity , means that there's no inclination for the fission products to leave this reactor. 新式反應爐內核不處在壓力狀態 而且沒有這種化學反應性 就表示不太可能讓核裂變產物 洩漏出反應爐
chemical:n.化学制品,化学药品;adj.化学的; reactivity:n.反应;反动;
So even in the event of an accident, yeah, the reactor may be toast , which is, you know, sorry for the power company, but we're not going to contaminate large quantities of land. 所以一旦發生事故 是的,這個反應爐會燒壞,就是說 電力公司,抱歉了 但它不會汙染大片土地
toast:n.干杯; v.为…干杯; contaminate:v.污染;玷污,毒害(人的思想或品德); quantities:n.数量;数目;大量;大宗;(quantity的复数)
So I really think that in the, say, 20 years it's going to take us to get fusion and make fusion a reality, this could be the source of energy that provides carbon-free electricity. 所以我真的覺得 這可給我們20年過渡時間 讓核聚變成為現實 這種能源 提供了無碳的電力
source:n.来源;水源;原始资料; carbon-free:adj.不含碳的;
Carbon-free electricity. 無碳電力
And it's an amazing technology because not only does it combat climate change, but it's an innovation . 這是非常令人驚歎的技術 不但可對抗氣候變遷 更是個創新
technology:n.技术;工艺;术语; combat:v.战斗;防止;减轻;与…搏斗;n.战斗;搏斗;打仗; innovation:n.创新,革新;新方法;
It's a way to bring power to the developing world, because it's produced in a factory and it's cheap. 可將能源帶給開發中國家 因為是在工廠生產的,所以很便宜
You can put them anywhere in the world you want to. 可裝置在任何地方
And maybe something else. 接下來我要談一些別的
As a kid, I was obsessed with space. 小時候我對太空非常癡迷
obsessed:v.使痴迷;使迷恋;使着迷;(obsess的过去式和过去分词)
Well, I was obsessed with nuclear science too, to a point, but before that I was obsessed with space, and I was really excited about, you know, being an astronaut and designing rockets, which was something that was always exciting to me. 嗯,我對核子科學也非常著迷 但在那以前,我對太空很著迷 我很興奮 希望能當太空人和設計火箭 總是讓我很興奮
But I think I get to come back to this, because imagine having a compact reactor in a rocket that produces 50 to 100 megawatts. 我覺得可以重拾童年夢想 只要火箭裡裝個小型反應爐 可發電50到100百萬瓦
That is the rocket designer's dream. 這是火箭設計師的夢想

propulsion:n.推进;推进力;

Martian:adj.火星的;n.火星人; community:n.社区;[生态]群落;共同体;团体;

than the low-enriched uranium fuel of these molten salt reactors, which means that the effects would be negligible , because you launch it cold, and when it gets into space is where you actually activate this reactor. 比熔鹽反應爐的低濃度鈾燃料更高 表示它的影響可以忽略 因為發射時反應爐還沒啟動 進入太空後才會啟動
low-enriched:低浓缩的; negligible:adj.微不足道的,可以忽略的; activate:vt.刺激;使活动;使活泼;使产生放射性;vi.激活;有活力;
