Pressure Vessel to Decommission Shillelagh Missiles
Nevada Weapons Test Site
 Leavitt Engineering was contracted to design a 10-foot diameter by 36-foot long
horizontal ASMA pressure vessel for the Tactical Demilitarization Project at
the Nevada Weapons Test Site. The vessel will be a prototype and field
demonstration unit used to remove propellant from the small, solid rocket
motors used by Shillelagh Missiles.
The vessel included a missile holder, gas conversion chamber, and gas holder
tank. The missile holder restrains the disassembled Shillelagh missile
during firing operations. The gas holder collects and contains exhaust gases
and particulates generated by the motor firing, and is connected to the
forward end of the gas conversion chamber.
 The project was
completed under the direction of Bechtel Nevada, Corp. Design teams
from Leavitt & Associates, El Dorado Engineering in Salt Lake City, Utah,
and CarFe, Inc., from Elko, Nevada, teamed up to completed the project. The
missile holder, gas conversion chamber, and gas holder were fabricated by
Coburn Industrial Manufacturing in Chicago, Illinois.
Leavitt Engineering designs, inspects, and tests ASME
pressure vessels, AWWA water tanks, API petroleum tanks, and UL-142 tanks.
