And then the fuel assemblies are placed into the reactor and the core is operated for about a year to eighteen months before it has to be re-fuelled and fresh fuel has to be put in.
燃料组件会被放置入，反应堆，还有核心会被运作大约一年，到18个月，在它再次燃烧，新的燃料需要加进去。
Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core.
Messier27 (M27)是个气体发射星云的典型例子，它是由于类似太阳的恒星耗尽了其核心的核燃料而产生的。
