A modular loading system may include structural beams and modular beams that can be located in a shipping container. The structural beams can be arranged in a first direction, and the modular beams can be arranged in a second direction that is approximately perpendicular to the first direction. The structural beams can include a fixed contact surface and an adjustable contact surface positioned opposite the fixed contact surface for stabilizing the modular loading system in approximately the first direction. The modular beams can include receiving notches sized to receive a locking bar for stabilizing the modular loading system in a third direction that is approximately perpendicular to the first direction and the second direction.

Diaphragm joint and convolutions, bottom screen diffuser, air stem, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel.

A method for preparing low level radioactive hazardous wastes (LLHZ) for disposal in a landfill. The method includes providing a softsided transportable container at a hazardous debris collection site, where the softsided container has at least three layers of materials, an outer, middle and an inner layer, where the middle layer is a water impervious material. Each layer has a closable opening located on the top of the softsided layer. Hardsided closed containers containing LLHZ located in the interior of the hard container are loaded into the interior of the softsided container. Each layer of the softsided container is then closed, and the package transported and shipped to a disposal site for burial.

A customizable hazardous material containment system including a plurality of rectangular fluid-capturing liners which are secured together via a plurality of overlapping side flanges which extend around the perimeter of the liners, the side-flange liner connection allowing for non-linear implementations of a hazardous material containment system. A drain port can be incorporated into the liner. The system can also be used as a secondary or tertiary hazardous material containment system.

The present disclosure provides for an above-ground mobile storage tank that can be used in a variety of different commercial applications. In one embodiment, the storage tank may comprise a tank shell, wherein the tank shell further comprises at least one floor wall, at least one top wall, and at least four side walls. The side walls may each be affixed to the floor wall and the top wall to from an interior tank space. Each of the wall panels may comprise a copolymer polypropylene material. The storage tank may also comprise a plurality of steel reinforcements, wherein each reinforcement is configured to encapsulate the tank shell. Each reinforcement may be affixed to a trailer, which is configured to transport the tank shell. The storage tank may also comprise a plurality of slip plates located on the trailer to enable the tank shell to float above the trailer.
