Abstract
The invention comprises a method for conducting a decontamination solution into a nuclear steam generator for radioactively decontaminating the nuclear steam generator. The invention also comprises controlling the level of the decontamination solution in the heat exchange tubes of the nuclear steam generator in a manner to raise and lower, sequentially, the level of the decontamination solution in the tubes so as to replenish the decontamination solution in the tubes and to carry away the radioactive contaminates.
