Generic PCSR

The aim of this generic PCSR is to demonstrate to the Nil, EA, and the potential operating organisations, prior to beginning constmction of the plant, that an APIOOO built on the generic UK site can make and satisfy claims as to its safety. 

This current document provides a detailed generic AP1000 PCSR for use in the commencement of Step 4 of GDA. Previous issues of the generic PCSR supported GDA Step 3. The prime development for this issue is the expression of the safety case in a clearer claims-argument-evidenee stmeture. It is expected that a final issue of the generic PCSR will occur to coincide with the end of Step 4 to encapsulate all of the safety claims-argument-evidence to support the DAC. 

This generic PCSR provides the basis for a living safety case, which will be developed fiulher as various supporting activities are completed. 

This generic PCSR is the top-tier document within the safety submission the suite of documents that have been produced for the GDA of die APIOOO, which collectively justify the safety, security, and environmental impact of the APIOOO in a UK context. 

The APIOOO safety case is based on a claims-arguments-evidence structure. The claims for the safety case are derived from the overall safety goals for nuclear power plants and the expectations of the UK regulatory regime. This generic PCSR is a coordinating document that presents the... 

It should also be noted that the current structure of the generic PCSR has been developed to be drawn upon and be aligned with IAEA best practice and calls on generic US design and safety... 

The site-specific PCSR must demonstrate to the regulators that potential operating organisations can make and satisfy various claims as to safety prior to beginning construction of an APIOOO built on a specific UK site. The generic safety arguments have already been made in this report the site-specific PCSR will be particularly developed to cover aspects such as effect of local conditions, site-specific risk evaluation and emeigency provisions, and site-specific environmental impact. 

The Environment Report (Reference 1.12).describes those elements of the APIOOO design that could directly impact a generic UK site. The Environment Report itself is supported by several technical reports, including the APIOOO Disposability Assessment - UKP-GW-GL-012 (Reference 1.13)andthe APIOOO Integrated Waste Strategy (Reference 1.14). Information from the Environment Report is used to imderpin those claims in the PCSR that refer to the management of environmental impact and radioactive waste disposal. 

Size of site to accommodate operation (D9 - discretionary). This criterion requires a demonstration that there will be sufficient area within the boimdaries of the nominated sites to allow secure operation of at least one new build nuclear power station. Atypical layout for the generic APIOOO plant is discussed elsewhere in Chapter 2 of this PCSR. With the exception of the parking area, the entire facility is contained within a perimeter fence that encloses approximately 10 hectares (ha). The site boimdaries for the SSA nominated sites enclose areas of between 75 ha and 298 ha (Reference 3.7). Allowing for ancillary facilities, the typical area estimated for the S SA nominated sites required for operational purposes is 3 0 to 50 ha. Hence, all of the nominated sites are sufficient area for at least one new build nuclear power station. The finalised layout will need to ensure that the constructed AP 1000 plant can be operated in a safe and secure marmer, with access to site (and nuclear materials) strictly controlled. The finalised layout will need to accommodate both generic and site specific requirements and meet with the approval of the regulators. 

Radiation monitoring this identifies the plant monitoring provisions throughout the lifetime. Details of site specific radiation protection programme are not included, as these will be subject to site licensee administrative arrangements and are not covered by the generic site PCSR. 

The Environment Report provides a summary of all the environmental and waste management assessment undertaken to support APIOOO build in the UK. The Environment Report refers to a generic site, details of which are provided in UKP-GW-GL-025, Characteristics of a Generic Site for a Nuclear Power Station (Reference 14.5) and which is discussed further in Chapter 3 of this PCSR. A similar approach will be taken to develop this report to reflect the features of a future real site. 

Decommissioning of the generic APIOOO design is addressed briefly in Chapter 16 of this PCSR, and an outline plan and technical specification for a decommissioning strategy is presented in Section 20 of the EDCD (Reference 14.2) and in Reference 14.28. 

Normally, a PCSR is associated with a specific site. In this case, it is generic and as such is a demonstration of the fitness for purpose of the design itself.
