![]() ![]() ![]() The mixer pump test has been evaluated to cover the use of either the existing ventilation system (241-A-702) or the ventilation system upgrade provided by Project W-030. Safety considerations for removal of the pumps will be addressed by separate safety documentation once that portion of the mission is defined. ![]() This document does not evaluate removal of the mixer pumps. The hazard and accident analysis is limited to the scope and impact of the mixer pump test, and therefore does not address hazards already addressed by the current AWF authorization basis. ![]() This document augments the existing AWF authorization basis as defined in the Interim Safety Basis (Stahl 1997), and as such, will use the existing Interim Operational Safety Requirements (IOSRs) of Heubach 1996 to adequately control the mixer pump test. An evaluation of safety considerations associated with operation of the mixer pumps for the mixer pump test is provided in this document. Installation of the pumps and equipment has been completed. USQD TF-96-1041 verified that the checkout testing of the installed equipment was within the current TWRS Authorization Basis. USQDs TF-96-0461, TF-96-0448, and TF-96-0805 verified that the installation of the in-tank video camera, thermocouples, and Ultrasonic Interface Level Analyzer (URSILLA), respectively, were within the current TWRS Authorization Basis. more » Unreviewed Safety Question Determination (USQD) TF-96-0018 verified that the installation of two mixer pumps into Tank 241-AZ-101 was within the current Tank Waste Remediation System (TWRS) Authorization Basis. The scope of this document is limited to the performance of the mixer pump test for Tank 241-AZ-101. The purpose of this document is to describe and analyze the mixer pump test for Aging Waste Facility (AWF) Tank 241-AZ-101 and to address the 'yes/maybe' responses marked for evaluation questions identified in Unreviewed Safety Question Evaluation (USQE) TF-94-0266. All equipment necessary for the mixer pump test has been installed by Project W-151. This process test is described in TF-210-OTP-001. This document contains the completed safety analysis which establishes the safety envelope for performing the mixer pump process test in Tank 241-AZ-101. This assessment will describe the methods, protocols, and practices to assure that equipment and systems do not have Y2K problems. A detailed description of system dates, functions, interfaces, potential Y2K problems, and date resolutions can not be described since the project is in the definitive design phase. The current tank selection and sequence supports phase more » I feed delivery to privatized processing plants. The scope of project W-211 is to provide systems for retrieval of radioactive wastes from ten double-shell tanks (DST). This document will not be updated and any dates contained in this document are estimates and may change. The purpose of this assessment is to give an overview of the project. This assessment describes the potential Year 2000 (Y2K) problems and describes the methods for achieving Y2K Compliance for Project W-211, Initial Tank Retrieval Systems (ITRS). This assessment will describe the methods, protocols, and practices to ensure that equipment and systems do not have Y2K = , The project is presently on hold, and definitive design and procurement have been completed. A limited description of system dates, functions, interfaces, potential Y2K problems, and date resolutions is presented. The information and experience gained during this process test will provide data for comparison with sludge mobilization prediction models and provide indication of the effects of mixer pump operation on an Aging Waste Facility tank. Two mixer pumps and instrumentation have been or are planned to be installed in waste tank 101-AZ to demonstrate solids mobilization. This assessment describes the potential Year 2000 (Y2K) problems and describes the methods for achieving Y2K compliance for Project W-151, Tank 101-AZ Waste Retrieval System. ![]()
