The power that corporations holds is awful. They should not be able to manipulate the political process in that way.

Yet, that doesn't mean that the opposition to Yucca Mountain is therefore right. If you care for the environment, you would want to have nuclear waste stored in a safe place. Purely disrupt the Yucca Mountain project is not a victory for enviromentalists, because the waste will remain unsafe.

And the issue of taxpayers having to pay for it is beyound the point - you shouldn't be stingy when it comes to enviromental responsibility.
