与过去50年建成的大多数以水为冷却剂的核电站不同,Natrium采用液态钠冷却技术,TerraPower方面称这一设计在安全性上具备优势。更具里程碑意义的是,这是40多年来美国监管部门首次批准采用非水冷却技术的商用核反应堆。该反应堆将在运行中维持一定量的过剩液态钠,并将其储存在大型绝热罐中,从而在电力需求较低时继续维持裂变反应,将多余能量以热能形式“存入”液态钠,以便在风电、光伏出力不足时释放,用于填补可再生能源的波动。鉴于核电机组在接近满负荷工况下运行效率最高,这种“热储能+调峰”的方案也被寄望于显著摊薄发电成本。

“When people get hurt around our products, we need to take every ounce of education from it that we can,” Jacob Zeiger, a senior air-safety investigator at Boeing, told me, when I visited the Boeing facility this past December. “These technical findings are sacred.” Within hours of any major incident involving a Boeing plane, Zeiger and his team are notified, and they may spend a week to ten days studying the damage and interviewing the crew, piecing together what went wrong. In 2008, for instance, the engines on a 777 stopped responding, and it crash-landed short of a runway in London, shearing off its landing gear. Afterward, a team of investigators re-created the plane’s fuel system in a Boeing lab. A small heat-exchange unit, they found, had accumulated ice during the flight. Every 777 has since been retrofitted with a new version of the unit. Thanks to decades of such refinements, today’s jets may be the world’s most reliable machines. Flying in them is less likely to kill you than walking on staircases.。快连下载对此有专业解读
