DEVICE FOR SUPPLYING A NEUTRON-ABSORBING FLUID INTO THE PRIMARY CIRCUIT OF A PRESSURISED WATER NUCLEAR REACTOR AND PROCESS FOR INCREASING NEUTRON ABSORPTION IN SUCH A REACTOR

摘要

In order to supply a neutron-absorbing fluid (B) to the primary circuit (5) of a pressurised water nuclear reactor, a container (1) which can be filled with a neutron-absorbing fluid (B) can be connected to the primary circuit (5) of the pressurised water nuclear reactor by a delivery pump (3) and a feeding line (10). Moreover, a pressure derived from the primary circuit (5) can be applied to the container (1) and delivery pump (3) via a pressure line (8). The delivery pump (3) can be driven by a turbine (11), for example. Also disclosed is a process for increasing neutron-absorption in the primary circuit (5), wherein a neutron-absorbing fluid (B) is supplied from a container (1) and a pressure derived from the primary circuit (5) is applied to the container (1).
