Experts voice safety concerns about new pebble-bed nuclear reactors -- ScienceDaily: Researchers advise caution as a commercial-scale nuclear reactor known as HTR-PM prepares to become operational in China. The reactor is a pebble-bed, high-temperature gas-cooled reactor (HTGR), a design that is ostensibly safer but that researchers in the US and Germany warn does not eliminate the possibility of a serious accident.
