Guidance & templates


Waste treatment and disposal routes:

  • Accessing LLWR Waste Services Guidance – July 2016
     This guidance provides an overview of the waste treatment, disposal and support services available through LLW Repository Ltd.
  • Map of treatment and disposal facilities
    This map shows the locations of organisations providing treatment and disposal services accessible through LLWR.
  • NWP/REP/124 Actuals Vs Forecast Data
    This document provides a summary of actual versus forecast waste diversion and disposal for FY2013/14, 2014/15 and 2015/16. The document compares actuals (as reported in the Waste Metric Dashboards) against forecasts from the UK Radioactive Waste Inventory 2013, the Waste Inventory Form 2013-2015 and the Joint Waste Management Plans for those years. 

Waste Hierarchy:

  • A Good Practice Guide on the Waste Hierarchy – May 2015
    The application of the Waste Hierarchy is mandated by UK policy and environmental regulation; and is central to the Strategy. It is recognised as good practice in all aspects of radioactive and non-radioactive waste management, and is an essential consideration for determining Best Available Technique.

Best Available Technique (BAT) / Best Practicable Means (BPM) resources:

Discrete Items:

  • Discrete Item Decision Summaries
    This resource is a library of LLW Repository Ltd decisions on whether particular items of waste are Discrete Items or Non Discrete Items. The decision summaries are intended to help waste producers decide whether or not waste items they propose to consign to the Repository, should be recorded as Discrete Items on the LLWR Waste Consignment Information Form.

Project Waste Management Plans:

Waste Informed Decommissioning:

  • Waste Informed Decommissioning Model – March 2016
    This waste informed decommissioning model aims to provide information and guidance on how waste informed decommissioning can be planned and executed in the nuclear industry. Waste informed decommissioning is a method of delivering decommissioning to ensure that the optimum decommissioning and waste management outcomes are achieved.

Boundary Waste:

On-site Decay Storage Principles:

  • On-site Decay Storage Principles (Issue 1) – Nov 2017
    This document aims to help waste producers in their decision making regarding the suitability of on-site decay storage for radioactive waste being managed. Four high-level principles have been developed along with a set of considerations that underpin the principles. These considerations clarify what the principles mean in practice by mapping out what a waste producer needs to consider before, during and after the decay storage period, addressing the full waste management lifecycle.

    The principles and considerations were developed through a desk review of UK policy, regulation and guidance in relation to the storage of radioactive waste and decay storage, and engagement with NWP stakeholders at a workshop and through review of the final On-site Decay Storage Principles document. The outputs of desk review and workshop are available below:

Managing the Non-radiological Properties of Radioactive Waste:

  • Introductory guidance on the managing the non-radiological properties of radioactive waste – May 2017
    This introductory guidance is designed to raise awareness on how to manage the non-radiological properties of radioactive waste consignments being diverted from disposal at the Low Level Waste Repository. Information on these properties may be requested by transport providers, landfill sites that accept Very Low Level Waste or Low Level Waste treatment facilities. The guidance document is split into 4 sections; sections 1-3 contain information on the regulation and management of non-radioactive waste; whilst section 4 introduces the 7 step process for classifying and coding non-radioactive waste, according to the Waste Framework Directive.

    In addition to this guidance there is an NWP eLearning module available; see the LLW Training Resources page.

Waste Classification:

  • International Approaches to Radioactive Waste Classification – Oct 2016 
    A comparative review of eleven approaches to radioactive waste classification: the model currently in use in the UK, those recommended by the International Atomic Energy Agency and the European Commission, and a further eight in use or being developed by other countries (Belgium, Finland, France, Japan, Spain, Sweden, Switzerland and the US).

Problematic Wastes

Whilst waste treatment and disposal routes are relatively well established for the majority of the UK LLW inventory, there is a population of wastes (known as problematic or orphan wastes) for which there are no identified or available treatment and disposal routes. Identifying these wastes and implementing waste management solutions supports effective decommissioning. Studies have been undertaken to identify the inventory of problematic LLW in the UK and to identify potential waste management solutions for some high priority wastes.

  • LLW Problematic Waste Technology Optioneering Summary Report 
    This document provides a summary of a technology mapping study undertaken in FY14/15 for the priority wastestreams identified from the problematic waste inventory compiled that year – contaminated oils and oil contaminated materials; inorganic and organic ion exchange resins; radium; and surface contaminated items.
  • Management of Contaminated Oils Feasibility Study – Mar 2015
    This report analyses the inventory of non-incinerable oils, provides an introduction to each of the 21 potential treatment technologies identified by the study and provides an assessment of the eight most technologies.
  • LAW Problematic Waste Summary FY 2015/16
    This document provides a summary of the Lower Activity Waste (LAW) problematic waste inventory collected from waste producers over FY 15/16. It includes information on the volumes of waste, type of waste for high volume groups and reasoning for problematic status.  
  • Management of Waste Failing the Discrete Item Limit – Feasibility Study
    This study identified a list of credible options that might be used for the effective management of waste failing the discrete item limit; as laid out in the LLW Repository Ltd Waste Acceptance Criteria. It covers three main waste groups: metals with simple geometries, metals with complex geometries; and cemented drums.

Problematic Waste Integrated Project Team:

In order to support delivery of the NDA’s 2016 Strategy, a Problematic Waste Integrated Project Team (IPT) was established in May 2016. Its objective is to develop a co-ordinated and improved approach to the industry-wide management of problematic radioactive waste. The IPT is being led by LLW Repository Ltd and RWM on behalf of the NDA and includes engagement with a range of stakeholders. Documents related to the IPT can be found on this section of the website. For further details of the IPT, please refer to the scope document below.
