It's entirely possible it's overblown, but I'm pretty sure we're talking about larger amounts than that if we're using this to get rid of our nuclear waste. But even apart from the launch risk, shooting stuff into space is not cheap, and shooting stuff into the sun is a lot more expensive than that. To justify that, it has to be not only safer, but also cheaper than putting it underground. The only real advantage I see to shooting it into the sun is that if our civilisation ever collapses and nobody can read anymore, there's less risk of the people then running into our waste in the sun than finding it buried.
