Waste Packaging & Encapsulation Plant Distributed Control System

Design and build of a Distributed Control System for the Waste Packaging & Encapsulation Plant. 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 WPEP Distributed Control System (DCS) project replaces the existing system with a replacement control system based on modern technologies, whilst applying relevant Sellafield standards, guides and procedures. The scope of activities are to include (but not be limited to):

a) Familiarisation with the existing control system to aid understanding. b) The production of detailed hardware and software designs, consistent with the relevant clauses specified in the standards and capable of satisfying the requirements specified in the User Requirement Specification (URS). c) Carrying out the manufacture and assembly of all items of hardware, consistent with the relevant clauses specified in the standards and capable of satisfying the requirements specified in the URS. d) Implementing structured software, consistent with the functional requirements documentation. e) Production and delivery of all supporting design documents, consistent with the relevant clauses specified in the standards and as listed in the URS. f) Preparation and submission of Technical Queries (TQs). g) Carrying out the detailed design and build of a simulation model, including the production of all supporting design documentation. h) Carrying out testing in accordance with the relevant clauses specified in the standards and as described in the URS. i) Carrying out training in accordance with the relevant clauses specified in the standards and as described in the URS. j) Delivery of the system to the location specified in the contract documentation. k) Provision of support during Setting to Work and Commissioning in accordance with the URS. Sellafield Ltd has appointed one (1) supplier to deliver the design and build of the DCS for the WPEP facility.

Additional information: The procurement was designed as a single lot covering the design, build, test, and delivery. Due to the nature of the requirement, keeping the scope as one single lot allows the appointed supplier to efficiently manage the full end-to-end scope of the project.
