REQUEST FOR ADDITIONAL INFORMATION FOR QUAD CITIES I & 2
~
l.
Identify any systems or equipment containing high points which may need venting (for example, the RHR heat exchanger) to maintain adequate core cooli ng.
Describe the methods and indications used to identify the need to vent, the equipment used to vent, and the vent flow path, and discharge
~
area of each of the above identified vents.
2.
If it were necessary to use the reactor vessel head vents in order to main-
~
'tain adequate core cooling post-LOCA, discuss the guide 1ines the operator would follow to use these vents including:
a) When to vent or not vent considering combustible pas concentration in containment, b)
Potential single failures in the vent path, including the failure of a valve to close, c) The effect of vent discharge on surrounding equipment.
