Equipment Preservation for a Four Year Outage of Pickering NGS Units land 2

Abstract

During the Pickering NGS Units 1 and 2 outage it was necessary to place systems in a state which would inhibit equipment degradation. This state is collectively known as "lay-up". The objective of this report is to transmit details of the organization to implement and maintain lay-up, and to report on problems and their solutions. Lay-up conditions for major systems are described. The lay-up techniques used during the retubing outage were successful, with little evidence of equipment degradation. Recommendations for similar applications of lay-up in the future are given. The thrust of this report is directed at organizational and operational problems.
