Results of Tests with Large Sacrificial and Self-cleaning Strainers and the Installation at Ringhals 2

Nuclear Energy Agency

The paper describes briefly activities performed by Vattenfall Utveckling AB at Älvkarleby Laboratory as part of the qualification programme for the new ECCS strainers at PWR plant Ringhals 2 based on the “robust solution” with large sacrificial strainers and a self-cleaning “wing-strainer” of same type as used for the five modified Swedish BWR plants. With the new knowledge gained from several BWR strainer projects following the Barsebäck strainer incident in 1992, the functioning of ECCS strainers for PWR was re-evaluated. The upgrading at Ringhals 2, a 3-loop Westinghouse plant having fibreglass and mineral wool as insulation, was the ...
