Patent DE-2128213-A1 (DE)
Title: Water cooled reactor control absorber - hydraulically activated by primary coolant
Inventor: DAUBLEBSKY PETER DR
IPC: G21C7/16
Filed: 1971-06-07
Abstract: A hydraulic actuator is integrally mounted within the reactor tank beneath the core, the reactor coolant being used as the hydraulic medium to apply press. to the actuator piston to drive the absorber into the core. A regulating counter press. is applied to the underside of the piston through a pipe line connected to an external source such as the water treatment or cooling water storage tank pumps. Controlled emergency insertion of the absorber is effected through a dump valve which relieves the regulating line fluid to a dump tank. The system is 'fail safe' since inadvertent loss of regulating line press. results in absorber insertion from reactor primary coolant press. Only one line connection through the tank is required for the regulating line.
