FORT ST. VRAIN DEW POINT MOISTURE MONITOR SYSTEM POST-MODIFICATION TEST RESULTS (RT-355C)

摘要

This report presents test results and evaluations obtained subsequent to the installation of dew point moisture monitor (DPMM) bypass valve actuators and sample flow controllers in the Fort St. Vrain HTGR. New sample loop filters were installed to obtain all test data for clean filter operation. Testing was accomplished by supplying primary coolant gas from the PCRV through the DPMM system to the reactor building ventilation system as was done in earlier testing reported in GA-A13677. This allows measurements to be taken independent of circulator operation.
