A -- SEEKING MATURE SENSOR TECHNOLOGY: SENSORS OR SYSTEMS TO ``ANTICIPATE'' DIFFERENCES IN PHYSICAL PROPERTIES OF LAYERS IN FRONT OF A CORE SAMPLER SOL TCBD95-04DF. DUE 062595. POC Dann J. Flesher, Phone 509-372-3640, Fax 509-372-2454, E-Mail Address: DANN_J_FLESHER@RL.GOV. NOTE: This is NOT a request for Development of Sampling Devices or Sampling Strategies. Westinghouse Hanford Company (WHC) is seeking a mature technology that has either a proven capability or a very high probability of success in ``scanning'' the matrix in front of a core sampling (core drilling) bit to detect abrupt changes or transitions in the gross physical properties of the matrix. The overall objective is to maximize core sample capture in sampling a layered matrix of radioactive chemical waste. The specific objective is to detect transitions from solid to liquid, liquid to sludge, etc. prior to penetrating the interface; this permits the timely change of sampling tools/techniques to maximize sample capture potential for all layers. Present sampling methods include a variety of sample tubes and modes; each permits the capture of waste with a specific range of physical properties. e.g., one tool will capture a liquid but may not permit capture of a wet crystalline solid. The needed sensor would detect transitions from one waste type to another (0 to 20 cm in front of the drill bit) before the sample tube enters the new layer. The configuration of the drill bit presents a physical constraint; the inside diameter is 1.25 inches, outside diameter 2.25 inches. To allow free sample passage into the sample tube, the sensor may be required to fit within the 0.5 inch thick annular wall. Other physical arrangements or sensor locations may be considered. Selection criteria will be technical merit, and cost. Late submittals may be considered ONLY if they offer significant technical advantages. Please provide the following: A) A Title/Name and description of the technology or device proposed, B) A statement describing maturity, including any past application examples, C) Any equipment or application cost information or rough estimates, D) Company Information: primary areas of expertise or company experience, E) Name of the individual acting as the contact for information exchange. WHC may enter into contract(s) related to these needs without further notice. NOTE: All pages of correspondence should have the solicitation number ``TCBD95-04DF'' clearly displayed near the top.
