IMPROVEMENTS RELATING TO HANDLING DEVICES FOR ABSORBER ELEMENTS IN A NUCLEAR REACTOR
Patent
·
OSTI ID:4101141
An arrangement in which the absorber elements are introduced into the reactor from beneath comprises a rod fixed to the absorber element able to slide within a vertical channel. The lower end of this rod is fixed to a flexible member, e.g., a cable with one end controlled by a winch. The other end, running over a fixed pulley, is connected to a counterweight. The arrangement is such that when the winch is decoupled from its drive motor, the counterweight provokes a rapid introduction of the absorber element into the reactor. Preferably the absorber element consists of a curved plate introduced into a corresponding cavity provided within the reflector. (IIB)
