The NEI blog posted something interesting today. Over at NEI they found a nuclear power plant simulator. It is an interesting little flash game that lets you set the control rod and coolant levels as you try to produce as much power as possible without causing a nuclear meltdown. You have two settings to choose from. "Normal" simulates a normal reactor, while "Difficult" simulates a reactor that has fallen behind on maintenance.
The demo version of game itself can be played at AE4RV by following this link. You can also play the full version of the game by downloading it. Consider this a small little indulgence at work or at school when you should be doing other things.
