Description: Currently, tank wastes are to be characterized by drilling and physically removing core samples. The cores are analyzed in laboratories in a hot cell environment. The purpose of the cone penetrometer is to bring the interrogative methods to the sample in its native environment, providing faster, safer, and more cost effective tank characterization, both in terms of time and effort. Probes currently exist for the physical characterization of tank wastes in terms of porosity, density, temperature, and electrical conductivity. The main tool for chemical analysis in the in-tank cone penetrometer will be a fiber optic Raman spectroscopy probe, which will be used to collect information about the molecular chemical constituents of the tank wastes. This report addresses the design and implementation of a Raman probe with the in-tank cone penetrometer. The scope of this document includes design specifications and recommendations for the following aspects of the in-tank Raman cone penetrometer probe: cone penetrometer probe interface--an unit for the inclusion of a Raman probe in the in-tank cone penetrometer will be described; window materials--chemically resistant and mechanically stable materials for the cone penetrometer probe interface window will be considered; Raman probes--Raman probes for inclusion in the penetrometer will be discussed.
