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

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.

Comparison with HSE_NII SAPs.pdf	Supporting Documents	20-06-2023	1.94 MB
This document provides an assessment of the UK EPR™ design against the HSE_NII Safety Assessment Principles (SAPs), which express HSE_NII views on relevant good practice in reactor design and operation, and against which it assesses safety submissions for civil nuclear facilities in the UK. This comparison between the UK EPR™ design and the expectations of the SAPs is intended to be a contribution to the demonstration that the EPR™ design process has followed "relevant good practice", as required by the guidance from HSE_NII in application of the ALARP principle. The EPR™ design was developed within a French and German framework involving both national Safety Authorities, following a specific set of recommendations for the design of new PWRs, known as the "Technical Guidelines", which were the fundamental requirements applied to the EPR™ design. Subsequently, the EPR™ design was compared against international standards such as IAEA safety guidelines, EURs and WENRA reference levels. These guidelines and principles do not correspond in all respects to the recommended practices suggested in the SAPs. Nonetheless, it is considered that all the key nuclear safety requirements embodied in the SAPs are met by the UK EPR™ design, and in particular that the UK EPR™ achieves the fundamental objective that the radiological risk to workers and the public is as low as reasonably practicable, which is the basic legal requirement underpinning UK nuclear safety regulations.
