Waste Solidification Process Control Program 14 1.0 DISCUSSION The purpose of the Process Control Program (PCP) for incontainer solidification is to provide a program which will assure a solidified product with no free standing liquid prior to transportation for disposal and which meets the re-quirements of 10 CFR 61.56, Waste Characteristics.
The PCP's for each waste stream included in this procedure are based on labora-tory testing, the results of which are included in " Topical Report Cement Solidified Waste to Masc the Stability Requirements of 10 CFR 61" prepared by Westinghouse. These PCP's are valid for all liner types using electric or hydraulic mixing heads provided by SEG.
The appropriate portions of this document shall be considered complete only when used with the operating procedures (OP llO4-28A for borated and oily wastes or OP 1104-28C for resin) for full scale solidification. This document describes the methodology for determining the acceptable ratio of waste, cement and additive that will result in an acceptable product for transportation and ultimately burial. The Solidification Data / Calculation Sheets convert these ratios into the recommended quantity of cement and additive that should be mixed with Class A unstable waste and the recommended quantity of coment and additive which must be mixed with Class A Stable and Class B or C wastes.
==- _- =----------------------------------------------------------------.
NOTE: Until regulatory issues are resolved concerning Class B and C waste forms (refer to Reference 2.10), this procedure shall only be utilized to perform verification testing of Class A unstable waste forms only.
