Fusion Reactor Breaks Even

mysqlbytes writes "The BBC is reporting the National Ignition Facility (NIF), based at Livermore in California, has succeeded in breaking even — 'During an experiment in late September, the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel — the first time this had been achieved at any fusion facility in the world.'"

The scientists send a press release to (presumably) a small number of news organizations (the BBC probably being one of them).

In order to get it, you need very extreme reaction conditions, and you need to actively maintain them. Unlike fission, the reaction won't simply maintain itself, once established, it only goes for as long as the temperature and pressure are right.

You stop firing the lasers, or stop feeding pellets, and the reactor stops.
