【 摘 要 】

Analyses of waste samples taken from tank 241-AY-102 indicate the tank interstitial liquid is deficient in nitrite in accordance with corrosion prevention chemistry. The supernatant was within specifications. Corrosion control is a Technical Safety Requirement (TSR) level control implemented in HNF-IP-I266 (CHG 2001 b), Administrative Control (AC) 5. IS, ''Chemistry Control Program.'' Sodium hydroxide (caustic) solution was added to the tank in early 2001 to bring it into specification for hydroxide. Sodium nitrite solution will be added to the tank to bring the interstitial liquid into specification for nitrite.
