This report concerns the continuing problem of providing waste tank designs which will insure safe storage of radioactive waste over long periods of time. These tanks must withstand severe stresses imposed by earth loading, by hydrostatic pressure and by temperature gradients. The temperature gradients are caused by contained in the waste. The waste entering the tank is relatively cold, but the temperature rises rather rapidly to the boiling point as filling proceeds and then the temperature continues to rise as self-concentration increases the boiling point of the waste. The temperature gradients are therefore transient in character and they may be …

Description
This report concerns the continuing problem of providing waste tank designs which will insure safe storage of radioactive waste over long periods of time. These tanks must withstand severe stresses imposed by earth loading, by hydrostatic pressure and by temperature gradients. The temperature gradients are caused by contained in the waste. The waste entering the tank is relatively cold, but the temperature rises rather rapidly to the boiling point as filling proceeds and then the temperature continues to rise as self-concentration increases the boiling point of the waste. The temperature gradients are therefore transient in character and they may be calculated only by rather tedious and complex methods; however, the gradients must be established in order to provide design data for structural design purposes. This report describes the methods used to calculate the temperature gradients and presents the calculated results for a particular tank design used under various operating conditions.
