7912190673 IE Information Notice No. 80-05 CHLORIDE CONTAMINATION OF SAFETY RELATED PIPING AND COMPONENTS A Bechtel Power Corporation Study at the Wolf Creek Project has revealed that a fire retardent coating is potentially corrosive in contact with stainless steel.
Albi "Duraspray" is a fire retardent coating which contains magnesium oxychloride, and is used for fireproofing of exposed structural steel in some Nuclear Power Plants.
There appears to be no deleterious effect when it is applied over unprimed, inorganic zinc coated, or galvanized steel, however, it may be corrosive in contact with stainless steel, bare aluminum or copper.
Droppings or overspray of this material cannot be properly removed with water.
Diluted Nitric acid has been proven to be a useful cleanser, however, it presents a safety hazard.
Applicants and holders of construction permits and licensees of operating power reactors are advised to protect all stainless steel, copper and aluminum material from overspray and droppage of cementitious oxychloride materials and to remove accidently applied materials immediately and completely employing strict safety precautions during the process.
Special attention should be given to weld areas in any removal procedures.
No written response to this information notice is required.
If you require additional information regarding this matter contact the Director of the appropriate NRC Regional Office.
