    DOCUMENTATION AND ANALYSIS FOR PACKAGING FOR SURFACE MOISTURE MEASUREMENT SYSTEM 7A CONTAINERS

    1.0 INTRODUCTION

    The purpose of this documentation and analysis for packaging (DAP) is to provide documentation demonstrating that two, procured, carbon steel 5-gal drums (UN/lAZ/Y36/S) meet all applicable U.S. Department of Transportation (DOT)-7A requirements. Corporation to transport two sources, one per container, to and from various 200 Area tank farms. One container will be used to transport a 0 009 Ci 252Cf source and the other to transport a 1.7 Ci 241Am-Be source. container incorporates a Site-fabricated adapter, which positions the source within the container cavity. Both sources will be transported onsite per the requirements of WHC-CM-2-14, Hazardous Material Packaging and Shipping, as separate items.

    1.1 BACKGROUND

    Radioactive wastes from defense operations have accumulated in underground waste storage tanks at the Hanford Site since the 1940s. Potential chemical fuels, in the form of ferrocyanide and various organic compounds, may be present in many of these tanks. Safety concernr have risen based on the possibility of condensed-phase chemical reactions propagating into undesirable consequences.

    Analyses and experiments indicate that the reaction propagat ion, and possibly its initiation, may be precluded by the presence of a sueficient concentration of moisture in the waste. If sufficient moisture i,j present in a fuel-containing waste boundary between an initiated reaction anti a dry stoichiometric mixture of fuel and oxidizer, modeling predicts that the water will absorb the energy released from the reaction so that it will not propagate through the waste boundary. concentration in the top layers of waste would, under current safety guidelines, provide evidence that the tank waste is in a stable and safe form for continued storage.

    Westinghouse Hanford Company (WHC), Science Applications International Corporation, ICF Kaiser Hanford Company, and HiLine Engineering and Fabrication, Inc., to determine the moisture concentration in the upper layers of the waste surface. The 252Cf source is lowered into the tank vapor space during this operation, and contamination o f t.he source is likely.

    observation wells (LOW) will be obtained with the Liquid Observation Well

    The existence of sufficient moisture

    The Surface Moisture Measurement System (SMMS) was developed by

    Moisture Measurement System (LOWMMS), which is controlled using the same data acquisition and control system as the SMMS. The LOWMMS moisture measurements of the waste surface immediately surrounding the LOWS will help confirm the surface moisture measurement obtained with the SMMS. The 24’Am-Be source is lowered into the LOW during this operation and will probably remaiin clean.

    A decontamination spray system is provided for cleanup of the SMMS as it is withdrawn from the tank. The decontamination system consists of a decontamination spool piece (attached to the riser), a feed pump, and a water tank truck. The decontamination spool piece is an impact force cleaning chamber with four high-pressure spray nozzles.

    2.0 PACKAGE DESCRIPTION

    2 .1 PACKAGING

    Both source containers are carbon steel UNlAZ drums, with open heads, which incorporate water-extended polyester (WEP) neutron shielding and a central cavity formed from steel pipe and pipe caps. The basic drums were fabricated by FBF Nuclear Containers, Inc., and tested to meet DOT-7A requirements per 49 CFR 178.350 and applicable sections of 49 CFR 173. interior cavities and WEP shielding were added to the basic drums by Frontier Technology Corporation, who is the actual supplier to WHC.

    nominally llf in. inside diameter by 12% in. high (inside). The interior cavity dimensions differ, depending on the source that will be used with them. The certification limits gross weight of the drums to 100 lb (normal weight is approximately 45 lb). Corporation drawings of the drums.

    The container for the 252Cf source has a basic cavity based on 2-in. schedule 40 pipe. A Hanford Site-fabricated adapter, which positions the source for easy attachment of a source handling tool, is installed in the cavity. The adapter replaces the original pipe cap for the cavity. It also provides a collar to allow connection of a polyethylene sleeve during source transfer between
