Report of Green Thread Pipe Installation at Laulualei, HI and Jim Creek, WA VLF Sites: Changes from 1997 to 2001

Abstract

This report summarizes the on-going study of Green Thread fiberglass piping that was installed at the Laulaulei, HI and Jim Creek, WA VLF sites. This Green Thread pipe was introduced to these VLF sites in 1996 and 1997, respectively, as a replacement for the original materials used to conduct cooling water to and from the power amplifier tubes. The Naval Research Laboratory was tasked with monitoring the changes in water quality with the aging of the Green Thread pipe. Yearly monitoring of standard chemical and physical variables significant for the sites such as: dissolved copper; pH, resistivity, dissolved organics, dissolved oxygen, sacrificial target use, Barnstead cartridge usage, PA tube failure rates, etc., is conducted. To date, the pipe has not introduced any apparent system degrading components.
