The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is planning to initiate operations in 2019 to destroy a chemical weapons stockpile that comprises of more than 500 tons of chemical weapons stored at the Blue Grass Army Depot (BGAD). In February 2003, following a detailed selection process among proposed methods for destroying the weapons at BGAD, the demilitarization process planned to eliminate these chemical weapons at BGCAPP was determined, including hydrolysis and the Supercritical Water Oxidation (SCWO) and Water Recovery System (WRS) processes.
The original demilitarization process plan was for the munitions and rockets to be disassembled to separate the agent from the energetics, which will then be mixed separately with either a caustic solution or water to destroy the chemical agent and energetics before being temporarily stored for later treatment. The resulting products are known as hydrolysate and are still considered toxic waste. The final treatment of the hydrolysates at BGCAPP would then use a SCWO-based secondary waste treatment system.
As part of PEO ACWA’s continuing assessment of processing systems and procedures for safe operation and compliance with the highest industrial safety standards, the plant’s Energetics Neutralization System (ENS), a key component to nerve rocket processing, is being replaced in the demilitarization process plan due to a number of identified operational, technical and safety risks. A new mature technology, which does not produce energetics hydrolysate, is being investigated to eliminate/significantly reduce risks associated with the ENS. As a result, the SCWO-based secondary waste treatment system will operate to process agent hydrolysate using an energetics hydrolysate surrogate.
The BGCAPP SCWO Facility consists of three (3) SCWO systems (or trains) with a series of upstream [Aluminum Removal System (ARS), Blend Tank System] and downstream (WRS) component systems. Owing to the removal of the ENS, the ARS will no longer be used in SCWO operations and an alternative option for feeding the energetics hydrolysate surrogate to the blend tank is being investigated. The focus of this safety assessment is the successful integration, operation and maintenance of the overarching system.
