Analysis of a feed and bleed procedure sensitivity study, performed with the SIPACT simulator, on a French 900 Mwe NPP

摘要

an extensive sensitivity study related to a feed and bleed procedure was carried out with the SIPACT simulator. This work was performed independently from the real procedures (events- or symptoms-oriented), which are Developed in the plant environment. We only look here at the combined effects of bleeding and its time of initiation, With the determining effect of an initial mass inventory and a residual power. The basic scenario we analysed is Related to a total loss of feed water without any bleed action.
