Abstract:
A core differential pressure and liquid control line apparatus for a nuclear reactor is described. The apparatus includes a first portion configured to be positioned within and extend through an opening in the pressure vessel wall. At least the first tube portion has a diameter less than the diameter of the opening in the pressure vessel wall. An annulus is formed between the exterior surface of the first tube portion and the pressure vessel wall so that a neutron absorbent can be injected into the pressure vessel at the location of the annulus. The apparatus further includes a second L-shaped tube portion configured to be coupled to the first tube portion, and a third tube portion configured to be coupled to the second tube portion. The open end of the third tube portion extends to an elevation above the core plate.
