1. A method of monitoring a position of a control rod disposed in a nuclear reactor vessel disposed in a radioactive environment, the method comprising:
(a) selecting, by a processor located outside a containment structure, a control rod position indicator coil arranged in a coil stack through an analog multiplexer located in a data cabinet mounted on a nuclear reactor vessel head inside the containment structure, wherein the coil stack is located proximate to a control rod disposed in the nuclear reactor vessel;
(b) passing, through the analog multiplexer, an analog signal from the control rod position indicator coil;
(c) receiving, by the processor, the analog signal from the analog multiplexer through a communication circuit located in the data cabinet mounted on the nuclear reactor vessel head inside the containment structure; and
(d) determining, by the processor, a position of the control rod based on the received analog signal.
