There are several international data collection systems from plant level There are several international data collection systems from plant level events (e.g. IRS) to component data (e.g. OPDE), and with different events (e.g. IRS) to component data (e.g. OPDE), and with different goals, technical assessment vs. public communication. goals, technical assessment vs. public communication.
