Title:
NUCLEAR POWER PLANT AND METHOD FOR OPERATING THE SAME
Document Type and Number:
WIPO Patent Application WO/1996/022605
Kind Code:
A1
Abstract:
A metallic ion easily forming a corundum construction is continuously left in a primary system cooling water during the operation of a nuclear reactor so as to prevent the deposition on the internal surface of a primary system cooling water piping of a divalent cobalt ion of cobalt-60 or cobalt-58 which is a main constituent of a radioactive nuclide which deposits on the piping when it forms a ferrite containing cobalt, thereby making it possible to securely reduce the dose of the piping.
