Cleaning Method for VLF Cooling Water System Development and History of Application With Step-by-Step Procedure

Abstract

In 1980 NRL Chemistry Division personnel analyzed a black solid forming on the walls of VLF transmitter tubes that was lowering the flow rates of the cooling water. Chemical analysis of the black solid showed it to be copper (II) oxide CuO. This result implied uncontrolled corrosion in these systems and it was apparent that the following efforts were needed: (I) evaluation of the corrosion processes causing the formation of this product; (2) design of a chemical cleaning approach to remove this solid; (3) development of methods to inhibit or slow the formation of the CuO. This report documents procedures used to clean the VLF water cooling systems and transmitter tubes.
