The page provides access to a series of quarterly reports on the GDA process. The reports, which summarise where we are and highlight the key challenges we face going forward, are part of our drive to increase the public understanding of our role in assessing the safety and security of new nuclear power station designs, and how we are progressing against our overall timeframe.
This report provides information on the work that we have been carrying out on the Generic Design Assessment (GDA) of Hitachi-GE’s UK Advanced Boiling Water Reactor (UK ABWR), and the re-mobilisation of the GDA project for the Westinghouse AP1000® reactor design, during the period July - September 2014.
This has been a period of significant progress when the Regulators completed Step 2 of the UK ABWR GDA and concluded that the project could continue to Step 3. We also began re-mobilising our project team to begin the work required to close out the 51 outstanding GDA Issues for the Westinghouse AP1000 plant design. This included a launch event to familiarise new assessors with the AP1000 technology and to brief all on the design changes that have occurred during the pause period of 2011 – 2014.
For the first time, this report includes the performance metrics for the UK ABWR project. These provide a clear overview of the status of the project in all of the technical areas, and our judgements on the quality of submissions and forward programme.
In this period we have also continued our work with the Multinational Design Evaluation Programme (MDEP).
This report provides an update on the work that has been undertaken so far during Step 2 of the Generic Design Assessment (GDA) of Hitachi-GE's UK Advanced Boiling Water Reactor (UK ABWR), as well as the regulators preparation for potential other GDA's.
ONR and Environment Agency will publish their technical assessment and summary reports on 28 August 2014 together with a statement on whether GDA of the UK ABWR will progress to Step 3.
This report provides information on the work that has been undertaken so far during Step 2 of the Generic Design Assessment of Hitachi-GEs UK Advanced Boiling Water Reactor (UK ABWR), as well our preparation for potential other GDAs.
This is the first routine quarterly report that we have provided since the regulators began technical assessment work on the UK ABWR. In this period we have also commenced our interactions with international regulators via the ABWR Multinational Design Evaluation Programme (MDEP), and undertaken preliminary discussions on the potential re-start of the AP1000 GDA.
This interim progress report primarily provides information on the work that has been undertaken in the Generic Design Assessment (GDA) programme during 2013. We have not provided routine quarterly reports during this period as we have not undertaken significant regulatory assessment work. Our work has concentrated on completing the reporting of our assessment of EDF and AREVA's UK EPRTM reactor and on preparations for assessment of Hitachi-General Electric Nuclear Energy's (HGNE) UK Advanced Boiling Water Reactor (UK ABWR).
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the UK EPR reactor design. Covering July-September 2012, it provides detail on the closure of a further six GDA Issues, as well as an update on overall assessment progress.
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the AP1000® and UK EPR reactor designs. Covering April-June 2012, it provides detail on the closure of a further two GDA Issues for the UK EPR reactor design, as well as an update on overall assessment progress.
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the AP1000® and UK EPR™ reactors. Itprovides detail on the closureof the first GDA Issue for the UK EPR™ reactor design.
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the AP1000® and UK EPR reactors. It follows the issuing of interim design acceptance by ONR and the Environment Agency in December 2011.
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the AP1000® and UK EPR reactors. It follows publication of our GDA Issues and the Requesting Party (RP) Resolution Plans in July.
This is our latest routine quarterly report on the progress of Generic Design Assessment (GDA) of the AP1000 ® and UK EPR™ reactors. It summarises the progress made to date and it identifies, for the first time, all the outstanding GDA Issues based on the completion of our planned assessment. These GDA Issues will be published in full on our website in mid July, and will form the totality of the GDA work still to be undertaken.
Following the unprecedented events in Japan, and the Governments request for Mike Weightman (HM Chief Inspector of Nuclear Installations) to provide reports on the implications and any lessons to be learned for the UK from the events in Japan, this Quarterly Progress Report looks at the likely implications for the Generic Design Assessment (GDA) timescales, rather than focussing on details of our ongoing assessment of the new reactor design generic safety cases.
HSEs main focus this last quarter has been on progressing the Step 4 assessments for both designs. This included a number of meetings with the Requesting Parties (RPs) to agree what further information they will provide during the coming months, and which areas are likely to require further work beyond June 2011.
On 18 October the Environment Agency completed its consultation on its GDA findings to date. Responses received have been published, and are currently being considered.
No showstoppers have been identified so far and, subject to further progress on some key areas in the next few months, we would expect to be able to issue a HSE Interim Design Acceptance Confirmation (DAC) and Environment Agency Interim Statement of Design Acceptability (SoDA) for each design on 30 June 2011.
This is the final substantial quarterly report of GDA before we publish our conclusions on 30 June 2011.
Progress continues on the assessment, however, it is expected that some limited GDA work will be required by the RPs beyond June 2011 to address some of the issues arising, therefore it is looking more likely that we could issue an Interim DAC rather than a DAC in June 2011.
Although we are confident that we can complete a meaningful assessment by June 2011, this remains a significant challenge and we are relying on the requesting parties to provide us with the appropriate, and timely information we require to complete our assessment.
Progress continues on the assessment, and we are signalling that some GDA work may be required by the Requesting Parties beyond June 2011, when we plan to complete our assessment of the reactor design safety cases. We are flagging up these issues, so that the Requesting Parties can either redouble their efforts to address them, or begin the process of developing credible Resolution Plans.
However, we have identified no issues so far that we believe cannot be resolved, and there is still time before June 2011 for the Requesting Parties to fully address our concerns. We remain confident that a meaningful assessment will be completed by June 2011.
Good progress continues on the Generic Design assessment (GDA) and although many issues remain open and require further work, the Requesting Parties are making good progress in addressing them.
The next key milestone will be the Environment Agencys consultation on the environmental part of the assessment,thiswillcommence on Monday28 June 2010. In parallel, HSE will continue to progress its detailed assessment for Step 4.
HSE and the Environment Agency remain confident that a meaningful assessment will be achieved by June 2011.
Good progress continues on the assessment, but many technical issues remain open and the successful clearance of these will require high quality and timely information from the Requesting Parties (RPs). We met a major milestone on 27 November 2009 when we published 33 comprehensive reports reflecting the progress made, and highlighting the issues identified during Step 3 of the assessment.
The next key milestone will be the Environment Agencys consultation on the environmental part of the assessment due to start in May 2010. In parallel, HSE will continue to progress its detailed assessment for Step 4.
We remain confident, subject to timely provision of information from the RPs, that a meaningful generic design assessment will be delivered in June 2011.
We continue to make good progress on our assessment, including working closely with the requesting parties and overseas regulators on the identification and resolution of technical issues. The HSE remains on course to publish its technical reports at the end of its Step 3 on 27 November 2009, and the Environment Agency is preparing for its consultation in 2010.
In July this year, our GDA assessment passed the half-way point on our programme. During that time, we have secured effective and efficient joint working, including introducing a one-stop point of contact for GDA and achieving levels of openness and transparency not seen before on this type of project.
We remain on course to complete a meaningful GDA in June 2011.
We have continued to make good progress on technical issues and assessment resources. We have also continued to work closely with the Requesting Parties, potential operators, overseas regulators and other stakeholders, as well as issuing guidance and discussion documents, and improving public access to information and ourselves.
General progress remains satisfactory towards a June 2011 completion for GDA of the two designs still undergoing GDA: the AP1000 and EPR, and also for the update (Step 3) reports being issued in November this year. Resource shortage remains a key threat to satisfactory progress, and mitigation measures are being implemented. Extensive interchange with industry, overseas regulators and other stakeholders continues.
