LLW Repository LtdNational Waste ProgrammeNWP/REP/011Issue 2.1 – Jan 2013Page 19 of 585. Waste Management StrategiesA range of waste management strategies and approaches have been, and are currentlyused by the NDA estate for management of their pond furniture waste. The toolkit ofapproaches employed by any specific SLC reflects the overall strategic intent of that SLCand the availability of waste treatment routes, balanced against available funding andschedules for waste retrieval.This section of the document provides summaries of the overall waste managementstrategies and individual waste techniques used by the NDA estate SLCs. Section 5.1provides a high-level “state of the nation” description of the SLC or site wastemanagement strategy applicable to pond furniture. This includes a list of the techniques incurrent routine use for management of this waste for each SLC. This listing is expanded insection 5.2 where technology summaries are provided for each technique. The R&Dactivities undertaken by NDA estate SLCs relevant to pond furniture are briefly describedin section 5.3, with examples of any trials undertaken associated with the R&D. A range oftechniques not used or being trialled by SLCs has been identified through literature reviewand these are listed in section 5.4. Case studies relating to the use of any specifictechnique on pond furniture or wastes analogous to pond furniture by the NDA estateSLCs are presented throughout sections 5.2 and 5.3 to illustrate the technologysummaries.5.1. NDA Estate Waste Management StrategiesEach NDA estate SLC has specific strategies relating to management of their specificwaste inventories. This section identifies and briefly describes the strategy relevant tomanagement of pond furniture for each SLC with an inventory of this waste. This includesa list of the techniques in current and routine usage at each SLC for pond furnituremanagement.5.1.1. Magnox Ltd.Magnox Ltd’s strategy for management of its sites involves undertaking preparatory workfor Care and Maintenance until 2028, and then transfer of the sites into passive quiescentstate until 2075 (specific timings vary for individual sites). The preparatory work for Careand Maintenance involves undertaking dismantling work to remove radiological and nonradiologicalplant and buildings where benefit cannot be achieved from deferring the work.Waste retrievals, decommissioning and demolition of fuel storage ponds are a key part ofthis preparation for Care and Maintenance [Ref. 9, 10]. The strategy for pond furnituremanagement is to use decontamination as far as practicable to down categoriseradiological waste, and then to either divert waste for re-use / recycle or to dispose ofwaste to an appropriate facility, where a specific waste route is demonstrated to be BestAvailable Technique (BAT).The techniques previously considered, employed or under consideration by Magnox Ltd.for the management of pond furniture include:• Size reduction• Direct disposal to LLWR• Direct disposal to GDF• Optimised disposal to LLWR• Physical decontamination• Chemical decontaminationA company owned by UK Nuclear Waste Management LtdNOT PROTECTIVELY MARKED
