False. You have to look no further than Chernobyl, or more recently, Fu-kushima in Japan to understand the potentially deadly consequence of using nuclear fuel. Large amounts of radioactive material can be released into the environment in case of an accident, as they were in these two cases. Another consequence of using nuclear fuel is the radioactive waste that is produced from nuclear plants. This waste has be managed carefully, and is a hazard as it remains radioactive for thousand of years. Also, nuclear fuel is not inexhaustible or renewable and is a limited resource.
