Description
The Waste Packaging and Encapsulation Plant (WPEP) is a two-line process plant designed for encapsulating Flocculant (FLOC) arisings from the Enhanced Actinide Removal Plant (EARP) process, waste from the Segregated Effluent Treatment Plant (SETP) and the Effluent Plant Maintenance Facility (EPMF). The waste is encapsulated in stainless steel drums within a cement mix. Filled drums are lidded, and then monitored before being stored, initially in the WPEP Store, before being exported for longer term storage in the Encapsulated Product Stores.
The aim of the project is to replace the existing WPEP Distributed Control System (DCS) with a replacement control system based on modern technologies, whilst applying relevant Sellafield standards, guides and procedures.
The project aims to:
• Replace the existing DCS hardware, system software and configuration with a modern control system ensuring that the plant continues to function in the same manner
• Incorporate the currently independent Drum Decontamination and Powders PLC functionality to the replacement WPEP control system
The operability of the replacement control system is to align, as closely as possible, to the existing control system to reduce the impact on operator training and the changeover between the two systems.
• The replacement control system will be installed such that the existing control system remains in situ, providing a fall-back in the event of delays or commissioning issues. However, given space constraints, it may not be possible to do this in all instances and some existing equipment may be removed prior to installing elements of the replacement control system.
Please note the duration of the contract is an estimate which will be finalised upon Contract Award.
