Fukushima and the UK nuclear industry


In March 2011 Japan suffered one of the worst natural disasters in its history when a massive earthquake and tsunami hit the country. This led to a serious nuclear accident at the Fukushima Dai-ichi site with repercussions felt across the international community.

Mike Weightman, then Chief Inspector of nuclear installations and head of the Office for Nuclear Regulation, reported on the implications for the UK nuclear industry following a request from the Secretary of State for Energy and Climate Change.

On this webpage you will find the Fukushima reports and associated news as well as information about 'Stress Tests' carried out in the wake of events at Fukushima.

Fukushima reports

Following the nuclear incident at Japans Fukushima Dai-ichi site, the Secretary of State for Energy and Climate Change formally asked Mike Weightman to provide a report to Government on the implications and lessons learnt for the UK nuclear industry.

Here you will find the interim report from May 2011 and the final report published in October 2011.

The Implementation Report (October 2012) provides a summary of the progress that has been made ion addressing the recommendations in the HM Chief Inspector of Nuclear Installations report on the implications of the Fukushima accident for the UK nuclear industry. In addition, this report also covers the outcomes of the European stress tests reports, both in terms of the national reports for the UK and the European level peer review.

Government response to Dr Weightman's report on Fukushima

Charles Hendry, Minister of State for Energy, made a Written Ministerial Statement to the House on 1 December to announce the Governments response to Mike Weightman's final report on Fukushima.

Interview with Mike Weightman

Mike Weightman talks about his final report into the Fukushima Dai-ichi accident and thelessons for the UK nuclear industry.

Technical advisory panel

The technical advisory panel provided advice on the scope of the final report into the implications for the UK nuclear industry following the events at Fukushima. Members include representatives from the Environment Agency, the National Nuclear Laboratory and various other experts and consultants.

Submissions from licensees

The submissions received for both the Interim and Final reports have been published in line with our policy on openness and transparency and our commitment to publish all submissions received. Where possible submissions have been published in full; however, some information has necessarily been withheld for reasons of security or confidentiality. The views expressed in the published submissions represent the views of the persons making the submissions. HSE accepts no legal responsibility for any errors, omissions or misleading statements contained in the submissions.

'Stress Tests'

In the wake of events at Fukushima, every nuclear power generating country in Europe agreed to carry out safety 'stress tests'. The tests, completed by licensees, involve a targeted reassessment of each stations safety margins in light of extreme natural events, such as earthquake and tsunami.

The stress test can be summarised as the licensed nuclear installations targeted reassessment of the relevant safety margins in light of the events which occurred at Fukushima: extreme natural events challenging the plant safety functions and leading to a severe accident.

National action plans

Reports to ENSREG

This report is the UK's Regulators National Action Plan (NAcP) for implementation of post Fukushima lessons learned produced in response to ENSREG's Action Plan.

It provides details of the current status and, where appropriate, the planned completion time of each individual item under points for each individual item from ENSREG's compilation of recommendations and suggestions.
