It 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

The application of the Waste Hierarchy is mandated by UK policy and environmental regulation; and is central to the delivery of the national LLW 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 and studies

Strategic BAT – this series of national strategic level optioneering studies provides guidance and technical underpinning for waste producers to inform their own local BAT / BPM assessments.

National Strategic BAT for organic LLW

National Strategic BAT for LLW metals

National Strategic BAT for Soil, Concrete, Rubble, and Granular Material LLW

LLW Asbestos and Asbestos Containing Waste: Gate B (Preferred Options) Study Report

BAT Resource Guide

Provides information to waste producers and other stakeholders on sources of information that could be used when undertaking a BAT/BPM assessment.

Nuclear industry code of practice (NiCoP) on the BAT

Presents the principles, processes and practices that should be used when identifying and implementing BAT for the management of radioactive waste.

Carbon Emissions Assessment: Low Level Waste Routes

A carbon footprint assessment has been completed for waste treatment and disposal routes for LLW available through LLW Repository Ltd’s Waste Services Framework.

Discrete Items

Discrete Item Decision Summaries

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.


NWP Container Signposting Resource

This Excel tool identifies containers currently available, previously in use, planned for use by the consignors or under development, as well as select overseas containers. It includes containers of potential relevance to the management of LLW as well as ILW that could be managed as LLW. It features hard-sided and soft-sided containers and provides a description of the container, its key features and limitations, and a contact organisation.

Packaging to 2050 of Low Level Waste Identified in the UKRWI

This report reviews the industries packaging needs to 2050 for waste identified in the UKRWI as LLW. It includes demand profiles for key containers. The report identifies potential gaps in container provision, barriers to the use of existing containers and additional work required to ensure that appropriate container provision will be available to support future LLW management up to 2050.

Project Waste Management Plans

Guidance on Project Waste Management Plans (PWMPs)

Guidance on how to use PWMPs and the benefits that result. A PWMP is a tool to aid waste management planning and communications between waste generating teams and waste management personnel. The use of PWMPs is considered best practice.

Project Waste Management Plan (PWMP) Template

An editable, blank template can be directly adopted by waste producers, adapted to form a site-specific PWMP, or used to improve an organisation’s existing processes where PWMPs are already in use.

Waste informed decommissioning

Waste Informed Decommissioning Model

Provides 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

Cross Boundary Waste Decision Making Guidance

Guidance on Decision Making for the Management of LLW/ILW Boundary Wastes

Provides guidance on decision making for management of wastes close to the LLW and ILW (Intermediate Level Waste) categorisation boundary.

Management of LLW and ILW/LLW Cross Boundary Pond Furniture

Provides strategic guidance on the UK-wide inventory of pond furniture and the current and credible near-term approaches for managing LLW and ILW/LLW cross boundary pond furniture. Pond furniture is the metallic architecture used for the storage and handling of irradiated fuel in cooling ponds, which has been or is being stored under water.

On-site decay storage principles

On-site Decay Storage Principles: Issue 1

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.

Managing the non-radiological properties of radioactive waste

Introductory guidance on the managing the non-radiological properties of radioactive waste

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.

Waste classification

International Approaches to Radioactive Waste Classification

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.

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 promising technologies.

LAW Problematic Waste Summary FY 2015/16

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.
