LLW Repository LtdNational Waste ProgrammeNWP/REP/011Issue 2.1 – Jan 2013Page 8 of 581. IntroductionPond furniture – the metallic architecture used for the wet storage of irradiated fuel – is aubiquitous wasteform across the Nuclear Decommissioning Authority (NDA) estate. It is acomplex wasteform from a waste management perspective due to its variability in type,physical geometry and radiological characteristics.Despite its ubiquity and its importance as a source of a significant volume of metallicwaste, pond furniture has not previously been considered in a national strategic context;for example, neither the National LLW Strategy [Ref. 1] or the <strong>Strategic</strong> Best PracticableEnvironmental Options (BPEO) assessment for metallic waste [Ref. 2, 3] specificallyreference pond furniture, instead focussing on radioactive metals as a whole. It isacknowledged that significant work has been undertaken by SLCs and the supply chain informulating, trialling and implementing waste management approaches for thiswastestream; however, the outputs of this work has not typically been widelydisseminated beyond individual organisations. This historical lack of knowledge transferand learning from experience has contributed to duplication of effort and, in some cases,implementation of non-optimised waste management strategies.This report intends to provide the first cross-NDA estate compilation of inventory data andwaste management approaches specifically for pond furniture, with the intent of providingan effective vehicle for the transfer of knowledge – particularly good practice, lessonslearned and innovation – across the NDA estate. It should be noted that this strategicguidance is not intended to supplant any existing, or developing, SLC or specific sitestrategies for the management of LLW, ILW / LLW cross-boundary wastes, ILW or pondfurniture; but rather seeks to augment any such local strategies and to provide anadditional tool to support waste practitioners in informed and underpinned decisionmaking.This document has been developed in collaboration with the NDA-estate SLCs and thesupply chain. Inventory information presented in this document is extracted from UKRWI2010, with additional validation of the data by the SLCs. The compilation of wastemanagement approaches has been derived using information submitted by SLCs and thesupply chain, supported where appropriate by literature review. Similarly, identification ofcross-estate issues and opportunities relating to the management of pond furniture hasbeen derived based on information provided by the SLCs.It is intended that this compilation shall be periodically reviewed to take account ofchanges in waste inventory, strategy, management approaches and technology; so as toensure that this document remains current and fit-for-purpose.A company owned by UK Nuclear Waste Management LtdNOT PROTECTIVELY MARKED
LLW Repository LtdNational Waste ProgrammeNWP/REP/011Issue 2.1 – Jan 2013Page 9 of 582. PurposeThis strategic guidance document intends to serve three main purposes:• To provide a UK-wide inventory of pond furniture detailing the types, volumes andknown or assumed radiological classifications of the waste. This will allow foridentification of synergies and opportunities for consolidated waste treatment acrossthe NDA estate, as well as providing the supply chain with better clarity on the natureof the predicted arisings of pond furniture to inform future service provision or elseimprovements to current service provision.• To provide a compilation of information on current and credible near-term futureapproaches being employed within the NDA estate for management of pond furniture.This is to enable sharing of information, best practice and lessons learned; and toenable the identification of synergies and opportunities between sites. This isaugmented by the inclusion of case studies on relevant wastes, where particulartechniques have been employed by SLCs for management of pond furniture wastes.• To provide decision making logic for waste practitioners based on the current wastemanagement practices, to complement existing waste management strategies and tosupport waste management decision making / optioneering.The intended benefits of the use of this strategic guidance document for waste producers,service providers, LLWR Ltd. and other stakeholders are summarised in Figure 1.Figure 1 – Benefits matrix for pond furniture strategic guidanceWho receives benefit?BenefitContribute to avoidance of the need for a secondUK LLWR through optimized waste managementpractices.More cost-effective waste management of pondfurniture due to knowledge transfer of bestpractice, lessons learned and innovations acrossNDA estate.Maximisation of opportunities for new orimproved service provision from management ofpond furniture through improved inventory andschedule data.Waste producerLLWR Ltd.Service ProvidersRegulatorsOther Stakeholderš ̌ ̌ ̌ ̌̌ ̌ ̌ ̌ ̌̌ ̌ ̌A company owned by UK Nuclear Waste Management LtdIt should be noted that whilst this document specifies a range of potential wastemanagement options for pond furniture (either in routine use or else in research andNOT PROTECTIVELY MARKED
