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 onestorage tank (3) for storing the neutron-absorbing medium and at least onefeed line (7)for connecting the reactor (5) and/or moderator tank and the storage tank (3)in amedium-routing and/or flowing manner, wherein an explosion-triggered orexplosion-drivenvalve (6, 10), a so-called squib valve, is disposed in the feed line (7)between thestorage tank (3) and the reactor (5) and/or moderator tank, said valve beingable to effect arapid and efficient initiation of the feeding of the neutron-absorbing medium,in particularof the rapid feeding of boron, to the reactor (5) and/or moderator tank.
