Waste Packaging & Encapsulation Plant Distributed Control System

Description

Design and build of a Distributed Control System for the Waste Packaging & Encapsulation Plant. Lot 1: 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.<br/><br/>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.<br/><br/>The project aims to:<br/><br/>• 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.<br/>• Incorporate the currently independent Drum Decontamination and Powders PLC functionality to the replacement WPEP control system.<br/><br/>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.<br/><br/>• 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.<br/><br/>The scope of activities are to include (but not be limited to):<br/><br/>a) Familiarisation with the existing control system to aid understanding.<br/>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).<br/>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.<br/>d) Implementing structured software, consistent with the functional requirements documentation.<br/>e) Production and delivery of all supporting design documents, consistent with the relevant clauses specified in the standards and as listed in the URS.<br/>f) Preparation and submission of Technical Queries (TQs).<br/>g) Carrying out the detailed design and build of a simulation model, including the production of all supporting design documentation.<br/>h) Carrying out testing in accordance with the relevant clauses specified in the standards and as described in the URS.<br/>i) Carrying out training in accordance with the relevant clauses specified in the standards and as described in the URS.<br/>j) Delivery of the system to the location specified in the contract documentation.<br/>k) Provision of support during Setting to Work and Commissioning in accordance with the URS.<br/><br/>The procurement will be carried out under the Open procedure. The scope of the contract includes the design, build, test & delivery to the Sellafield site.<br/><br/>Please note the duration of the contract is an estimate which will be finalised upon Contract Award.<br/><br/>Parties who are interested in potentially submitting a tender for this opportunity are requested to register on the shared service Nuclear Decommissioning Authority (NDA) OneNDA eCommercial Systems powered by Atamis, which can be accessed via the URL https://atamis-2464.my.site.com/s/Welcome . Parties who register on this system should then register against Atamis Project C13138 in order to access the Waste Packaging & Encapsulation Plant Distributed Control System opportunity in order to:<br/><br/>- view the procurement and tender documents,<br/>- ask questions or request further information using the inbuilt messaging facility; and<br/>- submit your tender response. Additional information: The procurement has been 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 will allow the successful organisation to efficiently manage the full end-to-end scope of the project.
