This document presents the Functional Design Criteria for installing Liquid Observation Wells (LOWS) into single-shell tanks containing either ferrocyanide or organic waste. The LOWs will be designed to accommodate the deployment of gamma, neutron, and electromagnetic induction probes and to interface with the existing tank structure and environment.

The purpose of this paper is to develop and document a proposed position on the performance of independent peer reviews on selected design and analysis components of the Title 1 [Preliminary] and Title 2 [Final] design phases of the Multi-Function Waste Tank Facility [MWTF] project. An independent, third-party peer review is defined as a documented critical review of documents, data, designs, design inputs, tests, calculations, or related materials. The peer review should be conducted by persons independent of those who performed the work, but who are technically qualified to perform the original work. The peer review is used to assess the validity of assumptions and functional requirements, to assess the appropriateness and logic of selected methodologies and design inputs, and to verify calculations, analyses and computer software. The peer review can be conducted at the end of the design activity, at specific stages of the design process, or continuously and concurrently with the design activity. This latter method is often referred to as ``Continuous Peer Review.``

The purpose of this paper is to develop and document a position on the number and location of temperature elements to be used in the Project W-236A, Multi-Function Waste Tank Facility (MWTF) waste storage tanks. The current preliminary design for the temperature element (TE) placement in the MWTF waste tanks is essentially a copy of the TE placement in existing Double-Shell Tanks (DST). The basis for the placement of these TEs in existing farms is not widely documented and was arrived at by consensus of participating engineers. Current designs call for 194 TEs in each tank on the primary tank bottom, sides, support pad, foundation, and on the secondary tank concrete walls, dome, and haunch. An additional 18 TEs are located in the waste itself on a temperature tree. The MWTF project office has determined and is seeking concurrence that temperatures in the primary tank bottom and walls, in the secondary tank concrete walls and dome, and in the primary tank support pad, and in the tank foundation, be monitored primarily in one quadrant instead of all four. It has also been recommended by personnel performing the thermal hydraulic analysis of the tanks that it would be desirable to know …

The purpose of this paper is to document a project position on required ventilation system design air flow rates for the waste storage tanks currently being designed by project W-236A, the Multi-Function Waste Tank Facility (MWTF). The Title 1 design primary tank heat removal system consists of two systems: a primary tank vapor space ventilation system; and an annulus ventilation system. At the conclusion of Title 1 design, air flow rates for the primary and annulus ventilation systems were 960 scfm and 4,400 scfm, respectively, per tank. These design flow rates were capable of removing 1,250,000 Btu/hr from each tank. However, recently completed and ongoing studies have resulted in a design change to reduce the extreme case heat load to 700,000 Btu/hr. This revision of the extreme case heat load, coupled with results of scale model evaporative testing performed by WHC Thermal Hydraulics, allow for a reduction of the design air flow rates for both primary and annulus ventilation systems. Based on the preceding discussion, ICF Kaiser Hanford Co. concludes that the design should incorporate the following design air flow rates: Primary ventilation system--500 scfm maximum and Annulus ventilation system--1,100 scfm maximum. In addition, the minimum air flow rates in …

Disclosed are detailed procedures for measuring the rate of gas generation by grout made from synthetic tanks wastes or actual tank material. Objective is to measure the rate of gas generation for various gases (H{sub 2}, N{sub 2}O, etc.) produced when grout, prepared using tank waste, is heated at 65 C. Experiments will also be conducted using grout from synthetic tank waste, as practice. Purpose is to provide data for evaluation of safety risks presented by gas generation in the grout vault after making grout with tank waste, as verification/confirmation for gas generation rates for the ANL testing.

Calculations were done to determine a recommended size for the liquid helium storage dewar, gas helium storage tanks, and liquid nitrogen dewar requirements. I recommend a Liquid helium storage dewar with a nominal size of at least 2500 liters (660 gallons), preferably 3000 liters (792 gallons). I recommend obtaining gas helium storage tanks with a maximum allowable working pressure (MA WP) of 250 psig or greater. Combined volume to be at least 5880 cubic feet (44,000 gallons). I recommend obtaining a second liquid nitrogen dewar at D-Zero, dedicated to the refrigerator, solenoid and VLPC systems. The ideal dewar would have a volume of around 16,000 gallons. It's MAWP needs to be greater than 55 psig.

Included in this engineering note are three separate calculation divisions. The first calculations are the determination of the required thickness of the LN{sub 2} subcooler flat head according to ASME code. This section includes Appendix A-C. The minimum plate thickness determined was 0.563 in. The actual thickness chosen in fabrication was a 3/4-inch plate milled to 0.594-inch at the bolt circle. Along with the plate thickness, this section calculates the required reinforcement area at the top plate penetrations. It was found that a 1/4-inch fillet weld at each penetration was adequate. The next set of calculations were done to prove that the subcooler internal pressure will always be less than 15 psig and therefore will not be classified as a pressure vessel. The subcooler is always open to a vent pipe. Appendix D calculations show that the vent pipe has a capacity of 1042 lbs/hr if 15 psig is present at the subcooler. It goes on to show that the inlet piping would at that flow rate, see a pressure drop of 104 psig. The maximum supply pressure of the LN{sub 2} storage dewar is 50 psig. Appendix E addresses required flow rates for steady state, loss of vacuum, or …

Three core samples, each having two segments, from Tank 241-U-201 (U-201) were received by the 222-S Laboratories. Safety screening analysis, such as differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and total alpha activity were conducted on Core 70, Segment 1 and 2 and on Core 73, Segment 1 and 2. Core 74, Segment 1 and 2 were taken to test rotary bit in push mode sampling. No analysis was requested on Core 74, Segment 1 and 2. Analytical results for the TGA analyses for Core 70, Segment 1, Upper half solid sample was less than the safety screening notification limit of 17 percent water. Notification was made on April 27, 1995. No exotherm was associated with this sample. Analytical results are presented in Tables 1 to 4, with the applicable notification limits shaded.

Components of the K-1 fan system were evaluated for structural adequacy to accommodate an actuator weighing 540 lbs. The components evaluated were the connectors between the actuator and the valve, the duct between the valve and the facility wall, and the stud anchors connecting the duct to the facility wall. The loads were deadload, snow, operating loads, and seismic loads. The components were found to be structurally adequate for these loads.

The purpose of this position paper is to document the decision not to acquire continuous air monitors (CAM`s) from government excess/surplus supplies. The procurement plan for equipment to be acquired for project W-236A, the Multi-Function Waste Tank Facility (MWTF), stipulates that radiation monitoring equipment will be supplied by WHC via the stock retained within the excess/surplus inventory or utilization of procured instruments from canceled projects. Technological advances within the radiation detection industry have ultimately outdated the instruments that are available within the excess/surplus stock. These machines represent the technology of the 1970`s era. The CAM models in use or within the excess/surplus supplies are obsolete and have been discontinued by the manufacturer. Therefore, the majority of the excess/surplus CAM`s are being reacquired and disassembled by instrument shops for in-house acquisition of spare parts for the instruments that are still presently in-service. It is being recommended by W-236A projects department that the strategy to acquire surplus/excess radiation monitoring devices be modified. The recommendation is to directly procure instruments that are equal to the technology available within this industry.

A multi-phase program was initiated in 1994 to test commercially available melter technologies for the vitrification of the low-level waste (LLW) stream from defense wastes stored in underground tanks at the Hanford Site in southeastern Washington State. Phase 1 of the melter demonstration tests was performed in vendor test facilities using simulated LLW and was completed during FY-1995. Test samples taken during Phase 1 testing were analyzed by independent laboratories who reported the analyses results to Westinghouse Hanford Company for integration and evaluation. The reported analytical results were integrated into an electronic data base using Microsoft Excel*5.0. This report documents this data base as of the end of FY-1995, and is supplemental to the Phase 1 LLW melter testing summary report, WHC-SD-WM-ER-498, revision 0.

This report summarizes the process test in which the airlift circulators in Tank 241-AZ-101 were shutdown. The test was successful, in that no extreme temperature excursions occurred. Only general data was obtianed through the use of a gamma energy probe.

Soon, there will be 4 independent core sampling systems obtaining samples from the underground tanks. It is desirable that these systems be available for sampling during the next 2 years. This assessment was prepared to evaluate the adequacy of the spare parts identified for the core sampling system and to provide recommendations that may remediate overages or inadequacies of spare parts.
