[en] This document provides a documented basis for the required design pressure rating and pump pressure capacity of the Hanford Site waste-transfer system in support of the waste feed delivery to the immobilization plant for processing. The scope of the analysis includes the 200 East Area double-shell tank waste transfer pipeline system and the associated transfer system pumps for all Phase 1B and Phase 2 waste transfers from AN, AP, AW, AY, and AZ Tank Farms

[en] An analysis of the 241SY tanks performed by ADVENT(1994b) to resolve dome overload issues indicated that the tank can sustain the dome loads resulting from additional soil overburden depth, increased soil density, and increased concentrated load. Similar issues exist for the 241AW/AN tanks and therefore, an interim analysis of the 241AW/AN tanks is presented herein. The scope of this effort is to review and compare all design drawings pertaining to the 241AW and 241AN tanks with those pertaining to the 241SY tanks; to modify the axisymmetric model of the 241SY tanks to represent the 241AW/AN tanks; and to evaluate the effect of additional dome load on the 241AW/AN tanks by performing a structural analysis for gravity loads (dead load + live load). ADVENT's additional scope of work is to perform a qualitative evaluation of the 241AW/AN tanks for seismic and thermal loadings (Blume 1976). This qualitative evaluation does not include any detailed finite element analysis of the tanks. Volume 1 of this report contains the text and calculations. Volume 2 contains a printed copy of the computer files used in these analyses

[en] Underground single-shell waste storage tanks located at the Hanford Site in Richland, Washington, generate gaseous mixtures that could be ignited, challenging the structural integrity of the tanks. The structural capacity of the single-shell tanks to internal pressure is estimated through nonlinear finite-element structural analyses of the reinforced concrete tank. To determine their internal pressure capacity, designs for both the million-gallon and the half-million-gallon tank are evaluated on the basis of gross structural instability

[en] This document provides structural load requirements and their basis for maintaining the structural integrity of the Hanford Single-Shell Tanks during waste feed delivery and retrieval activities. The requirements are based on a review of previous requirements and their basis documents as well as load histories with particular emphasis on the proposed lead transfer feed tanks for the privatized vitrification plant

[en] This engineering analysis documents the results of a study to establish the allowable vacuum to prevent bottom uplift or buckling of steel liner during waste retrieval activities of single-shell tanks (SSTs) located on the Hanford Site near Richland, Washington. Current OSD-T-151-00013 (2002) limits on SST vacuum are too restrictive as the tanks approach empty during waste retrieval. A summary of the SST liner design parameters is provided in Table 1. Buckling or uplift of the dished bottom and cylindrical sidewall portions of the carbon steel liners are investigated for each of the twelve SST tank farms taking into account predicted losses in liner wall thickness due to general corrosion as given in the Appendix. The additional vacuum in excess of the self-weight and residual waste to cause uplift of flat bottom tanks (A and AX) or buckling of the dished bottom tanks (all other SSTs) is very small except for the 200-Series SSTs. In general, the buckling of the steel liner due to internal vacuum is elastic and the bottom portion of the liner controls the allowable vacuum when the tank is empty provided that the general corrosion of the sidewall portion of the liner is not significantly greater than that of the bottom portion of the liner. This is not always the case if the predicted high corrosion loss for the liner sidewall of some SSTs is realized. This document provides a documented basis for the allowable vacuum to prevent bottom uplift or buckling of single-shell tank steel liners during waste retrieval activities

[en] Using static, linear analysis techniques, the reinforced concrete tanks have been evaluated for soil (depth and density) loads and concentrated load (applied at grade above the tanks) greater than those in the original design analysis. The original seismic, thermal creep and concrete aqinq analyses/assumptions have not been changed
