Powernet: Use of Steam Cleaners for Boric Acid removal...

[Jeff . Carey]

SONGS HPD would like to know if your plant allows the use of Steam Cleaners for removal of Boric Acid deposits on pipes, valves, and other surfaces that have started to or could lead to corrosive damage? San Onofre is considering the use of these type of machines to more effectively decontaminate and/or remove Boric Acid deposits from identified leaks. Information regarding Engineering approvals requested/received for the use of this process on plant components and structures would facilitate the use of steam cleaning machines at SONGS. Also request specific safety instructions considered for the use of the machines and any specific training that may have been considered/implemented for the use of the machines. A report on the effectiveness of these machines would also be appreciated.
