- a eD C av eu IE Information Notice No. 80-05 Date: February 8, 1980 Page 1 of 1 CHLORIDE CONTAMINATION OF SAFETY REIATED 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 zine 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 hezard.
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 remov5 recidently applied materials immediately and cospletely employing strict safety precautions during the process. Special attentior 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.
