3.1.1.2 Thermally Actuated Delune Valve. A valve designed to open when j
the local ambient temperature exceeds a preset value and remains in its full open position without any external power source. This allows the GDCS pools and surpression pools to drain into the lower drywell region in the event that the reactor core melts through the reactor pressure vessel during a severe accident.
