The article certainly doesn't state anything new. Fail safes such as the "freeze plug" or the ship to order model or the lack of pressurization are not new. On the flip side though, at least we're seeing this resurgence (in public interest) in nuclear technology whether it be MSRs or other Generation IV+ reactors. Maybe having private companies make significant progress on a tight budget is what it takes to drive further funding from large governmental bodies, just as in the Space industry.
