Special Agents: Chemical Weapons Disposal Done Right

Background:

After the Chemical Weapons Convention in 1993, a treaty was signed that required all participating countries, including the US, to destroy their chemical weapons stockpiles in a safe, effective way. These rockets contained lethal and volatile mustard agents, VX nerve agents, or GB nerve agents.

In addition, due to the projectiles being stored for a prolonged period of time at separate storage facilities in different climates, some of the rocket casings had warped and some of the chemical agents had congealed. Due to the complex nature of this project, the disposal process was far behind schedule before CRG was brought in, but the treaty deadline of September 2023 had not moved.

Challenge:

Destroying chemical weapons leaves no room for error. It requires specific processes, technology and expertise to achieve the goal of safely destroying a chemical stockpile of munitions that were never meant to be disassembled. Given the parameters and the timing, a full-proof yet nimble disposal protocol hadto be developed that allowedfor immediate emergency washdowns if a leak occurred.

A punch-and-drain system was developed, where the nerve agent was removed by a controlled puncture of the munition cavity to allow for the nerve agent to drain into a specialized mixture of water and caustic solutions resulting in hydrolysate. The munition was then moved on a conveyor to a controlled static detonation chamber (SDC).

While this process was safe and effective, any leakage would trigger the disbursement of a proprietary caustic chemical washdown to decontaminate the nerve agent. These cleaning agents could severely damage the robots, resulting in a complete facility shutdown which would cost thousands of dollars for every minute/hour/day it was not operational as wellas make the approaching deadline untenable. To insure against this, CRG outfitted their specialized robots with Roboworld’s Robosuits^®.

Solution:

To stay one step ahead of an emergency event or routine cleaning, Robosuits that could withstand the 20% Sodium Hyroxide, high-pressure hot water, or low-pressure steam were selected to keep the robots fully operational.
