Chapter 3 - Aspects having a Bearing on the Environment during Operation Phase.pdf	Pre-Construction Environmental Report (PCER)	20-06-2023	425.25 KB
Chapter 3, Aspects having a Bearing on the Environment during Operation Phase, comprises 4 sub-chapters. Sub-chapter 3.1 provides a general introduction and gives an overview of the interfaces of the UK EPR™ with the environment. Sub-chapter 3.2 outlines the different phases and activities that will take place during the UK EPR™ operational phase, including outages and maintenance, emphasising those that will potentially have an impact on the environment because they either use natural resources or generate wastes and discharges. Sub-chapter 3.3 identifies the aspects of the operational phase, which have a potential impact on the terrestrial environment for an operating UK EPR™. The Control of Major Accidents Hazards linked to hazardous substances stored and / or manipulated on the site is addressed here. Sub-chapter 3.4 identifies the aspects of the operational phase, in terms of both requirements for natural resources and outputs, which have a potential impact on the aquatic environment, for a coastal or estuarine operating UK EPR™ Unit.

Sub-chapter 20.2 describes how the principles and regulations discussed in PCSR Sub-chapter 20.1 have been followed at the early UK EPR™ design stage to ensure and facilitate future decommissioning in a safe and environmentally acceptable way. It describes the measures adopted at the EPR™ design stage to minimise the volume of radioactive structures, reduce the toxicity of the waste, lower the activity level of irradiated components, restrict the spread of contamination and permit easier decontamination, facilitate the access of personnel and machines and the removal of waste, and ensure the collection of building and operating data needed to prepare for decommissioning. An estimate of the volumes of low and intermediate level waste is also given, together with a discussion of the disposability thereof. Finally, the baseline decommissioning strategy currently envisaged is presented. Download

Sub-Chapter 18.3 - Abnormal Operation.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	259.75 KB
Sub-chapter 18.3 describes the operating principles to be applied to the UK EPR™ plant outside of normal operation. Emergency operation and severe accident conditions are defined. The operating principles for both of these conditions are defined, as far as they can influence the plant safety assessment. The emergency operating principles address plant operation following an accident, when operator actions are needed, and are based on a plant State Oriented Approach. Operating principles concerning severe accidents are outlined, covering the scenarios taken into account in the safety analysis (described in Sub chapter 16.2). Additionally the principles that would be applied in developing an Emergency Plan for the UK EPR™ are described. Download
Sub-Chapter 18.2 - Normal Operation.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	652.91 KB
The PCSR contains assumptions and requirements necessary to ensure the results claimed in the overall safety case. Operating documents will need to be defined in order to ensure that the plant is operated consistently with these assumptions and requirements. Sub chapter 18.2 outlines the methods that will provide design limits and conditions for the UK EPR™. It details the arrangements for moving the PCSR to an operating regime which will ensure that the requirements and assumptions contained in the PCSR are captured in operating documents. During normal operation the plant must be operated to manage normal scheduled operating transients and specific operations involving unplanned events, and in a manner consistent with the safety case assumptions. This is achieved using the principles and procedures for normal operation described here, and by establishing operating rules for normal operation. Download
Sub-Chapter 18.1 - Human Factors.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	1.18 MB
Sub-chapter 18.1 describes how Human Factors (HF) principles, methods and standards are integrated into the UK EPR™ design and operating concepts. It explains the objectives and scope of HF integration including the use of operating experience from previous plants to improve the design from a HF viewpoint. It presents a set of safety arguments as to how human performance will contribute to the achievement of nuclear safety and provides evidence to support those arguments. The Human Based Safety Claims that are part of the overall Nuclear Safety demonstration for the plant are identified and the requisite evidence (e.g. task analyses) to support these claims is presented. The requirements of the human machine interface design are described. The assurance process that underlies the achievement of adequate human reliability to support the overall nuclear safety demonstration is described. Download
Sub-Chapter 17.6 - Conclusions of EPR ALARP Assessment.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	71.14 KB
Sub-chapter 17.6 provides the conclusions of the UK EPR™ ALARP assessment, and concludes that the design of the UK EPR™ complies with the overall requirements of the ALARP principle, which is a key safety design objective for the UK EPR™. Download
Sub-Chapter 17.5 - Review of Possible Design Modifications to Confirm Design meets ALARP Principle.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	240.98 KB
UK regulatory guidance on the application of As Low As Reasonably Practicable (ALARP) for new civil reactors recommends that there should be a clear conclusion that no further reasonable practicable improvements could be implemented in the reactor design, and that therefore the risk has been reduced to ALARP. Sub-chapter 17.5 provides an ALARP assessment methodology, and an ALARP assessment of several UK EPR™ design alternatives, based on modifications required by international regulators in their assessment of the EPR™, or modifications implemented in the Sizewell B PWR. None of the modifications considered is indicated as reasonably practicable according to the quantitative ALARP assessment methodology. Download
Sub-Chapter 17.4 - Review of PSA Results: Comparison with Numerical Risk Targets.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	141.13 KB
Sub-chapter 17.4 summarises the results of the probabilistic safety analysis (PSA) for the UK EPR™ (presented in Sub-chapter 15.5 of the PCSR), which demonstrates that the risk to the public due to accidents meets the ONR targets for 'Broadly Acceptable' risk. It is confirmed that UK EPR™ safety design objectives for risk (presented in Sub-chapter 3.1 of the PCSR) are achieved, and therefore that the risk from UK EPR™ operation is likely to be in the broadly acceptable region. Download
Sub-Chapter 17.3 - EPR Design Optioneering.pdf	Pre-Construction Safety Report (PCSR)	20-06-2023	194.48 KB
Sub-chapter 17.3 describes the optioneering process carried out in France and Germany between 1987 and 2006 to develop the EPR™ design, and the design review carried out by independent safety experts on behalf of the French and German safety authorities. The outcome of the design optioneering process in terms of the principal design options that were selected and rejected to achieve a balanced design, in terms of the fundamental requirement to minimise risks to workers and the public, while achieving practical constructability and a cost-effective design, is presented. The rationale for the evolution of the design, and the improvements from predecessor designs, are explained along with the reasons why certain features were selected and others rejected. It is demonstrated that the process of design optimisation adopted to minimise risk due to accidents and to optimise operator dose in normal plant operation and accidents is closely analogous to the formal UK approach of ALARP.
