  • Electropolishing method for decontamination purposes
    Patent number: 5019228
    Abstract: An electropolishing method for decontaminating component parts in nuclear facilities includes enriching deionized water with an electrolyte that can be processed by a water processing plant present in the nuclear facility in order to assure electrical conductivity, and electropolishing with the deionized water.
    Type: Grant
    Filed: July 28, 1989

  • Method for the chemical decontamination of metallic parts of a nuclear reactor
    Patent number: 4756768
    Abstract: Chemical decontamination of metallic parts of nuclear reactor installation in which an oxidative treatment with a permanganic acid solution is applied before dicarbonic acids are used for further treatment. Rinsing operations are eliminated and smaller amounts of dicarbonic acids needed. Also the primary system of the nuclear reactor no longer requires emptying before effecting decontamination treatment.
