SYSTEM AND METHOD FOR THE ACCELERATED FEEDING OF A REACTIVITY-INFLUENCING MEDIUM INTO A HEAVY-WATER-MODERATED REACTOR

摘要

The invention relates to Method and System for the accelerated feeding of areactivity-influencing medium, in particular a neutron-absorbing medium, to aheavy-water-moderated reactor (5), in particular a pressurised water reactor,comprising at least one storage tank (3) for storing the neutron-absorbingmediumand at least one feed line (7) for connecting the reactor (5) and/or moderatortankand the storage tank (3) in a medium-routing and/or flowing manner, wherein anexplosion-driven valve (6, 10), a so-called squib valve, is disposed in thefeed line(7) between the storage tank (3) and the reactor (5) and/or moderator tank,saidvalve being able to effect a rapid and efficient initiation of the feeding oftheneutron-absorbing medium, in particular of the rapid feeding of boron, to thereactor (5) and/or moderator tank.
