Valve Houses are designed to use for the disposal of low-level radioactive waste from the demolition and decommissioning of the Portsmouth Gaseous Diffusion Plant located in Piketon, Ohio.
Because of the deep embedment depths, five options were investigated. In Option 1, cast-in-place construction without any stirrups in the walls. In option 2, cast-in-place construction with stirrups in walls and base slab. In option 3, stepped construction without stirrups in which thicker wall was proposed to use at bottom and thinner wall at top. Option 4, cast-in-place construction with only stirrups at bottom third of the wall and use uniform thickness along the wall.

GANTRY MOUNTED HOPPER DESIGN FOR SOIL PLACEMENT TRIALS FOR PETROLEUM RESEARCH NL, CANADA
The purpose of the gantry mounted hopper structure is to place the soil by launching the material from the end of a high-speed conveyor into a gantry-mounted hopper. The soil would then fall by gravity on the basin floor while the position of the hopper is controlled so that approximately 150 mm thick lifts are produced.
The soil is intended to place in a container floor and the hopper structure is required to move both along the length and the width of the container. To achieve the required movement, the hopper is mounted on a gantry (cart) structure and then the gantry is mounted on the top of the perimeter longitudinal beam of the container.
The dimensions of the hopper bucket are 1880 mm (6’ 2”) x 1200 mm (4’ 0”) x 1000 mm (3’ 3”) high. The gantry (cart) structure is designed with a square horizontal frame with dimensions 2440 mm (8’ 0”) x 2440 mm (8’ 0”). The existing container was purchased to place the soil with the overall dimensions of 12200 mm (40’ 0”) x 2440 mm (8’ 0”) x 2740 mm (9’ 0”).
The container was strengthened with “A” frames since the roof of the container was removed to accommodate the movement of the hopper.
The design loads from dead, live, wind, snow and soil loads are based on ASCE7-05.
The structural models were developed using structural design software STAAD.Pro and the analysis was performed using AISC 360-05 (2005). Moving load analysis was conducted in which the hopper travels on gantry (cart) and the cart travels along the length of the container, and designed the corresponding structures for controlling loading condition.
The lifting lug components were designed according to ASD.
The connections between the structural members are also designed for the dead and soil loads.
The base plate and anchors were designed to fasten the container to the floor.
