Testing, Storage, Supply and Delivery (Including provision of QA Documentation) of Drax Pulverised Fuel Ash

Tender description

Magnox Ltd is a wholly-owned subsidiary of the Nuclear Decommissioning Authority (the "NDA"). Magnox Ltd is responsible for the safe and secure operation and clean-up of 12 nuclear sites around the UK on behalf of the Nuclear Decommissioning Authority. The contract will be collaborative across the NDA Estate, providing the following sites with access to the agreement: o Magnox Limited o Sellafield Limited - a wholly owned subsidiary of NDA from 1 April 2016. o Dounreay Site Restoration Limited (DSRL) - a Site Licence Company under a Parent Body Organisation (private sector consortium) model: Cavendish Dounreay Partnership Ltd (Cavendish Nuclear, CH2M Hill, URS). As Magnox Ltd has the largest requirement, they shall be the Contracting Authority. Both Sellafield Ltd and DSRL will gain access to the contract, via a joining agreement. Lot 1: PFA (Pulverised Fuel Ash) is a bi-product of burning pulverised coals in coal-fired electricity power stations and is used to encapsulate ILW. Power Minerals Limited (PML) are the only provider of PFA from Drax which meets both BS EN 450-1:20126 and the SL Technical Specification for cement powders. Drax power station will cease burning coal in March 2021 as the UK moves away from coal-fired electricity. As each Participating Entity works on the scientific development of a replacement for PFA, a stockpile is required to ensure that the encapsulation process can continue. The following sites require access to Drax PFA: • Sellafield • Magnox • Dounreay Total Quantity or Scope Each Participating Entity is at varying stages regarding moving away from Drax PFA. The requirement for each site's stockpiling (in Tonnes) is as follows: o Magnox Limited - 700T o Sellafield Limited - 300T o Dounreay Site Restoration Limited - 500T Start date: 01/04/2021 End date (up to): 31/03/2028 The proposed end dates for each site is as follows: o Magnox Limited - up to 31/03/2028 o Sellafield Limited - up to 31/03/2022 o Dounreay Site Restoration Limited - up to 31/03/2027 The proposed contract will stockpile PFA at a dry store facility in Hixon. The contract will include break clauses with 6 months written notice to exit if Drax PFA is no longer required by the sites as a result of successful trials for alternatives to PFA. Hixon Dry Store Facility: There are no on-site storage facilities at any of the Participating Entity's sites therefore storage will be provided by the supplier. All sites will receive bulk deliveries of PFA, to avoid handling PFA from bag to a silo due to H&S and relevant skills issues. Bulk Storage Bags: All Drax PFA shall be 'double-bagged' in white woven polypropylene bags that are unprinted. 'Double-bagging' reduces the ability for moisture build-up within the bags. The size of all bags shall be 100x100x200cm with white top loading and bottom discharge spout. Testing: The PFA will be tested against both BSEN standards and the Sellafield Ltd specification throughout its lifecycle.
