“…In his work, Divine (Divine 1985) noted that caustic cracking of U-bends occurred at 140°F in concentrated caustic solutions or in dilute environments. In both cases, the dangerous concentrations are outside the limits given by the corrosion specifications (Kirch 1984).…”

“…Average anion data, Table 2, the chemical species critical to compatibility of the waste with the tanks, has been taken from the Hanford files and abstracted from the noted documents. These data have been evaluated using the relationships developed by Divine et a1 (Divine 1985) and corrosion is not considered to be a concern. All tanks are in compliance with flammability, waste compatibility, and criticality requirements though SY-101 and SY-103 are carefully monitored for flammable gases because of their high rate of gas production.…”

Key Words: double-shell tanks (DSTs), integrity assessment report, ultrasonic inspection, UT examination, design evaluation, tank farms, primary tank, secondary tank liner. Reference Document: WAC-173-303Abstract: This report presents the results of the integrity assessment of the 241-SY double-shell tank farm facility located in the 200 West Area of the Hanford Site. The assessment included the design evaluation and integrity examinations of the tanks and concluded that the facility is adequately designed, is compatible with the waste, and is fit for use. Recommendations including subsequent examinations, are made to ensure the continued safe operation of the tanks.Charge Code: 106699/CA40 PURPOSEThe purpose of this integrity assessment is to evaluate the condition and determine if the SY Tank Farm tanks were adequately designed with sufficient structural strength and compatibility with the waste so that they will not collapse, rupture, or fail during the facility's use. The assessment will provide conclusions and recommendations.The following shall be considered:Design Standards: identify and evaluate the standards and requirements to which the tank system was designed and constructed.Waste Characteristics: identify the waste (past and projected) and evaluate the compatibility of the tank components with the waste.Corrosion Protection Measures: identify the material and evaluate the design and operational practices for corrosion protection.A HNF-4859. Rev. 0Age: document, estimate, or otherwise determine the age of the system.Integrity Examinations: identify the existing condition of each component material based on leak testing, visual examination, and ultrasonic inspection. SCOPEThe scope of this integrity assessment is the primary steel tank and the secondary steel-lined concrete tank for all three SY double-shell tanks. The integrity assessment of the transfer pipelines and pits associated with the SY tank farm is not included in this report. The assessment of these pipelines and pits was reported in Double-Shell Waste Transfer Piping/Pit System Integrity Assessment Report (Hundal 1997). DESCRIPTIONThe SY tanks were similar to the earlier double-shell tanks (AY, AZ) as well as to the later AW, AN, and AP tanks. The double-shell tank design evolved with experience and with changing national design standards, but all are very similar.As shown in Figure 2, the tanks are domed cylinders with two shells, the 75-ft. diameter steel primary tank and the 83-ft. (outside diameter) steel-lined concrete shell (USAEC 1974).' There is a 30-in. annular space between the primary steel tank and the secondary tank, and an 8-inch thick insulating concrete layer between the tanks' bottoms. Below the design liquid level, the contents are contained by two separate tanks, both having leak detection systems. The steellined concrete tank is about 48 ft. high from the top of the foundation to the top of the dome. The dome is elliptical, with semi-axes of 40 A. and 15 ft. A concrete foundation pad that is almost 90 ft. in diameter...
