John H. Large is a Consulting, Chartered Engineer and analyst primarily known for his work in assessing and reporting upon nuclear safety and nuclear related accidents and incidents. From the mid-1960s until 1986 Large was an academic in Brunel University's School of Engineering, where he undertook research for the United Kingdom Atomic Energy Authority. As a Consulting Engineer with Large & Associates (), Large led the nuclear risk assessment team for the raising of the damaged Russian nuclear submarine ''Kursk'', which assessed the nuclear hazards and defined the limits and conditions under which the lift and recovery of the submarine in 2001 took place. Also, he advised the Government of Gibraltar on nuclear safety aspects of the repairs being undertaken to the nuclear propulsion reactor on board HMS ''Tireless'' throughout 2000, he investigated the adequacy of emergency planning in the event of a nuclear-powered submarine radiation incident whilst berthed in the UK port of Southampton, and he released an updated review following the retrieval of classified documents relating to the risks and hazards of nuclear-powered submarines berthing at Southampton and elsewhere in the United Kingdom. Large has been critical of the nuclear power industry, and has been commissioned in the past by Greenpeace and other national and international NGOs to provide technical analysis on nuclear issues. In 2003 a paper Large submitted for publication to the Institution of Mechanical Engineers about the danger of a terrorist attack on UK nuclear installations was suppressed on the advice of the UK government. In March 2011, he appeared on Al Jazeera English, Sky News, Channel 4 and BBC News〔(【引用サイトリンク】title=John Large speculates on the Fukushima Nuclear Power Plant explosion )〕〔(【引用サイトリンク】title=Expert assessment on radiation leak 14 March 2011 - 18.35GMT )〕 and ITN〔(【引用サイトリンク】title=Meltdown threat: Japan 'preparing for worst' )〕 giving his assessment that the Fukushima Dai-ichi reactor containment had been compromised in the hydrogen explosions, leading to a dangerous release of radiation. This contradicted information released both by the operators and by the Japanese Government. On 23 March 2011 John Large appeared at the ALDE Group Open Hearing at the European Parliament with an Intervention that strongly challenged the proposals of the European Energy Commissioner Günther Oettinger to review the European Community nuclear safety requirements following the radiological incidents at Fukushima. More recently (2015) Large provided opinion and evidence in an ongoing civil action in Japan contesting the restart of the Sendai Nuclear Power Plant and he prepared an assessment of the effectiveness of the Japanese Nuclear Regulation Authority (NRA) recently introduced guide for the evaluation of nuclear power plant sites with respect to the potential affects of volcanic effects, specifically aligning this to the Sendai NPP presently proposed for restart following a four-year shut down in the aftermath of Fukushima Daiichi. Large has been invited by the Chief Nuclear Inspector of UK Office for Nuclear Regulation to join the Technical Advisory Panel working on the ONR's assessment of the implications for the UK nuclear Industry of the Fukushima Dai-ichi nuclear accident, although following failure to negotiate terms and conditions for the appointment he opted out of the appointment. Instead, instructed by Greenpeace Germany and Greenpeace France, Large prepared a critical review of the preliminary report of the IAEA Fact Finding Mission undertaken to Fukushima Dai-ichi in May 2011. Throughout 2013 Large advised Friends of the Earth on the engineering and technical aspects of the Southern California Edison San Onofre Nuclear Generating Station at which Units 2 and 3 are presently shut down because of faults in the steam generators. Large has prepared written evidence,〔(【引用サイトリンク】title=In the Matter of Southern California Edison Company, San Onofre Nuclear Generation Station, Units 2 and 3, Response to Atomic Safety and Licensing Board's Factual Issues, 1st Affidavit of John Large )〕〔(【引用サイトリンク】title=In the Matter of Southern California Edison Company, San Onofre Nuclear Generation Station, Units 2 and 3, Comments on the NRC and SCE Responses of January 30, 2013, 2nd Affidavit of John Large, )〕 to the Atomic Safety and Licensing Board (ASLB) of the Nuclear Regulatory Commission (NRC) in which he explores reasons for the extensive tube wear and damage in the San Onofre steam generators and whether the nuclear plant should be permitted to restart operation. Friends of the Earth submitted a Review〔(【引用サイトリンク】title=Review of the Mitsubishi Heavy Industries and other Documents Relating to the Procurement and Design of the San Onofre Replacement Steam Generators )〕 by Large to the NRC Petition Review Board under the 2.260 Petition Process seeking a hearing relating to the de facto License Amendment process. In June 2013 Southern California Edison announced that both San Onofre nuclear reactors would not be restarted and that plants would be permanently shut down and decommissioned. In November 2014, following a spate of overflights of French nuclear power plants by unmanned aerial vehicles (UAV), Large provided evidence to the French Parliament in the open session of l'Office Parlementaire d'Evaluation des Choix Scientifiques et Technologies (l'OPECST), both by spoken intervention relating the vulnerabilities of French NPPs to drone intrusion - the Large & Associates assessment and report on the drone activity, commissioned by Greenpeace France remains confidential although it has aroused considerable media speculation.〔(【引用サイトリンク】title=CE QU'IL FAUT SAVOIR DES DRONES UTILISÉS )〕 Large is frequently interviewed or quoted in the media.〔(【引用サイトリンク】title=News Snippets )〕 John Large is an experienced apiarist and in his spare time he manages the apiary at the Oxleas Wood Apiary in South London. Throughout its restoration, John Large acted as the Technical Advisor to the Trustees of the Severndroog Castle Building Preservation Trust with the present reinstatement of this 18C folly located at Shooters Hill in South-East London. ==Sources== *(The Recovery of the Russian Federation Nuclear Powered Submarine Kursk ), Society of Naval Architects and Marine Engineers, World Maritime Technology Conference, Sans Francisco, October 2003 *(Risks and Hazards in Recovering the Nuclear Powered Submarine Kursk ), Royal Institution of Naval Architects, 23–24 June 2005 *(Forensic Assessments of the Nuclear Propulsion Plants of the Submarines HMS Tireless and RF Northern Fleet Kursk ), Institution of Mechanical Engineers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Large」の詳細全文を読む スポンサード リンク
