2020:07 Fibre Clogging in Nuclear Power Plants
SSM perspective Background Emergency core cooling systems in boiling- and pressurized water reactors use strainers. Their purpose is to out foreign material suspended in the cooling water so this material ... increased the surface size of the strainers, to avoid them from being clogged. The risk of accumulation on the strainers is increased pressure drop over strainers, potentially causing cavitation in the emergency...
