Federal regulators are proposing to add computer security standards to their criteria for installing new computerized safety systems in nuclear power plants. The US Nuclear Regulatory Commission (NRC) quietly launched a public comment period late last month on a proposed 15-page update to its regulatory guide "Criteria for Use of Computers in Safety Systems of Nuclear Power Plants."
