Digital nuclear reactor control rod position indication system

Patent Reid, J.B.

A description is given of a digital nuclear reactor control rod position indication system employing a plurality of Hall Effect transducers longitudinally spaced along the control rod drive housing. The transducers are individually responsive to a magnetic field generated by a magnetized portion of the control drive rod to respectively provide an output when in substantial proximity to the magnetized rod portion. The transducer outputs are multiplexed to display the relative position of the control rods within the reactor core. (Official Gazette)
Thermocouple based control rod position indication system

Patent Heibel, M.D.; Impink, A.J. Jr.; Grobmyer, L.R.

This patent describes a rod position determination method. It comprises: measuring core coolant inlet temperature; measuring core coolant assembly exit temperature associated with a control rod; determining enthalpy rise from the inlet and exit temperature and a reference for an assembly containing the rod; determining the rod position charge; and determining the rod position from the rod position change and a reference rod position.
Control rod position indication system

Patent Impink, A.J. Jr.; Heibel, M.D.; Grobmyer, L.R.

An axial rod position determination system is described for a control rod in a nuclear reactor core, said system comprising: fixed incore detectors; analytical, on-line signature means for periodically creating a response signature database of expected detector response deviations for assumed rod positions from a reference detector response produced at the current rod position by said fixed incore detectors; and rod position determination means for continuously determining a moved rod position of the control rod by scanning the signature database for a signature match between the expected detector response deviations and current detector response deviations produced by said fixed incoremore »« less
Nuclear reactor control rod drive with rod position indicating means

Patent Ripley, C.C.
INDICATION OF CONTROL-ROD POSITION

Journal Article Bryden, R.D.; Simm, K.J. - G.E.C. Atomic Energy Rev.

The following ways of indicating the position of control rods for a large power-producing reactor are discussed: position of each control-rod group at the control desk; position of each rod by means of individual indicators on a display panel; and a permanent printed record of all significant changes in group positions with the time of the change. Also, descriptions are given of a control- rod winding mechnnism and position transmitter instaliation. (J. H. M.)
