【 摘 要 】

This engineering study evaluates the corrosion mitigation effectiveness of the annulus ventilation systems for the 241-AN, 241-AP, 241-AW, 241-AY, 241-AZ, and 241-SY tank farms, and provides the technical basis for the Administrative Control for DST annulus ventilation systems. The study shows that maintenance of annulus ventilation is important to mitigating risk of condensation and resulting corrosion due to postulated water ingress into DST annuli.
