sub-chapter_6.2_-_details_of_the_effluent_management_process.pdf	Generic Design Assessment, Pre-Construction Environmental Report (PCER)	20-06-2023	424.43 KB
Sub-chapter 6.2 details the effluent management process (collection, processing, storage and disposal) for liquid and gaseous radioactive discharges and solid radioactive waste. It identifies the sources, nature, treatment and storage of liquid and gaseous effluent discharges. It discusses the chemicals associated with liquid effluent that could be discharged into the marine environment, including the purpose of each substance, the main circuits involved, the path from injection to discharge, and the proposed maximum amounts discharged. Information is also given regarding the UK EPR™ radioactive waste and spent nuclear fuel strategy, including waste treatment and interim storage and disposability. The strategy takes into account the UK EPR™ solid radioactive waste and spent fuel characteristics, and addresses the government and NDA policies for the assessment of disposability of radioactive waste. It includes the description of processes and interim storage facilities for managing the waste and spent nuclear fuel. Download
Solid Radioactive Waste Strategy Report.pdf	Supporting Documents	20-06-2023	5.94 MB
This document presents waste and spent fuel management options to the Flamanville 3 reference case for the UK EPR™. The SRWSR describes how solid radioactive waste and spent fuel generated by the UK EPR™ over its complete lifecycle can be managed within the constraints of the current UK Government Policy and regulatory requirements. The SRWSR describes and characterises the predicted arisings of solid radioactive waste and spent fuel from the UK EPR™, and sets options for waste and spent fuel treatment, conditioning, packaging, record keeping, storing, transporting and disposal. It identifies the facilities required to manage waste and spent fuel arisings of a single EPR™ for up to 100 years from the start of its 60 year operational life. It also considers the impact of multi-reactor units as a variant to the base case configuration. A description of the Waste Treatment Building for operational waste and Interim Storage Facilities for Intermediate Level Waste and for spent fuel for the UK EPR™ are provided. The SRWSR describes how the generation of waste will be avoided or minimised where reasonably practicable. Download
RWMC Mapping.pdf	Supporting Documents	20-06-2023	666.55 KB
This mapping document demonstrates how a Radioactive Waste Management Case (RWMC) can be achieved for the UK EPR™. The wastes considered are the higher activity radioactive wastes, including spent fuel, that are generated through operation, maintenance and decommissioning of a UK EPR™. Intermediate level waste and spent fuel are dealt with separately in this document to provide clear and concise references and to conform to the guidance provided to nuclear licensees by the UK Regulators. This mapping for the RWMC provides a demonstration that support for safe operation of plant, processes and activities associated with the UK EPR™ will comply with regulatory requirements. Furthermore, this document provides evidence that there is a commitment by the licensee to meet national and international standards of radioactive waste management for the waste streams produced by the UK EPR™ design. The conclusion is that the RWMC requirements are addressed to a level of detail that is appropriate to this stage of the GDA process. Download
PPC application - diesel generators.pdf	Supporting Documents	20-06-2023	810.97 KB
This document provides relevant information about UK EPR™ installations that could be subject to Pollution Prevention Control (PPC) Regulations 2000 (now incorporated into the Environmental Permitting Regulations). Within the Generic Design Acceptance phase, the only installation identified as being subject to a PPC permit are the standby emergency diesel generators, as the total thermal input of these combustion plants will exceed 50 MW. The standby emergency diesel generators only operate for around 100 hours per year; nevertheless, it is a requirement of the application for a PPC Permit that the installation and the process equipment, technology and management controls be assessed against indicative Best Available Techniques (BAT) defined in relevant Sector Guidance Note. Therefore this document provides an assessment of BAT, with justification of the processes and / or equipment used to explain how it is or will have to be answered on site by the Operator. Download
Monitoring of liquid and gaseous discharges.pdf	Supporting Documents	20-06-2023	392.18 KB
This document provides additional details on the monitoring regime for both liquid and gaseous effluents prior to discharge that could be implemented on the UK EPR, by looking at the arrangements currently in place on existing stations, both on the 1300 MW French fleet and at a German KONVOI site. Monitoring arrangements for both liquid and gaseous effluents are presented, including both radiochemical and associated chemical substances, from their production through to collection, storage and discharge. The information given here provides additional detail to that presented in PCER Sub-chapter 7.3 (radioactive effluents), PCER Sub chapter 7.4 (chemical associated with radioactive effluents) and PCER Sub-chapter 6.2 (management of liquid effluents). The document does not deal with monitoring of substances in the environment, which has been dealt with in Chapters 11 and 12 of the PCER. Download
Longer Term Spent Fuel ISF.pdf	Supporting Documents	20-06-2023	795.27 KB
This document demonstrates that the risks over the lifetime of an interim storage facility for spent fuel are as low as reasonably practicable. Information is provided covering the design safety principles and safety aims for the storage facility. A preliminary assessment of hazards and risks is provided to demonstrate that the risks over the lifetime of the facility will be controlled to levels that are as low as reasonably practicable (ALARP). The means by which the need for active safety management during longer-term storage has been minimised are described. The characteristics of the fuel and equipment whose integrity must be maintained over the storage period are identified, including their evolution over that period. Potential fuel damage and containment degradation mechanisms are described, together with options for dealing with damaged fuel. The provisions and functions necessary for the retrieval and inspection of spent fuel and potential inspection regimes are discussed, including consideration of changes to the retrieval and inspection regimes as materials age and their characteristics change. Finally, plans for final fuel retrieval are outlined. Download

Interim storage facility for spent fuel.pdf	Supporting Documents	20-06-2023	1.05 MB
This document presents a clear and concise description of the design and operation of the proposed wet (pool – base) interim storage facility for spent fuel assemblies from a UK EPR™ plant. The nuclear safety principles are described and an outline of the safety provisions and functions is presented. The document lists the legislation and safety requirements that will be met by the plant, and describes how these will be implemented. None of the features are novel, they all employ proven technology. Cask, fuel handling, and pool storage have been successfully used around the world at a large number of sites with positive feedback. The document demonstrates that there is nothing in the proposed design that will not conform to UK legislation and standards, and concludes that the proposed interim storage will be suitable for licensing, construction and operation in the UK.

Integrated Waste Strategy Document.pdf	Supporting Documents	20-06-2023	517.36 KB
This Integrated Waste Strategy (IWS) document outlines the current strategy for managing radioactive and non radioactive wastes arising from the construction, operation and decommissioning of the UK EPR™. It shows that there is a management strategy for all the waste streams produced by the UK EPR™ design and that they have been suitably planned for. The IWS refers out to a range of other UK EPR™ GDA submission documentation which provide more details on the how, why and when waste management strategies on the UK EPR™ are developed. The document shows that waste management strategies have been developed using a standardised approach which takes into account all relevant factors including: delivery of compliance with relevant regulatory obligations and Government policy; consideration of a full range of health, safety, environmental, security, economic and social issues; minimisation of waste via implementation of the waste hierarchy; and application of Best Available Techniques (BAT). The IWS identifies uncertainties and assumptions that may influence the implementation of an EPR™ waste management strategy in the UK and also recognises the risks and opportunities within the strategy.
