Dutch consortium set up to develop of molten salt reactors
04 March, 2021
The Nuclear Research and Consultancy Group (NRG) in the Netherlands said on 2 March that it had set up a consortium, along with TU Delft, DIFFER, and reactor developer Thorizon to accelerate the development of molten salt reactors (MSRs). Recent technological developments made by the partners provide the basis for the further design and testing of important processes and materials to be able to build an MSR, NRG noted. As well as producing energy, an MSR can also provide high-quality heat for industry. This type of reactor is also ideally suited for the use of thorium as a fuel, NRG added.

NRG continues project on graphite ageing in AGRs
14 September, 2017
A new irradiation capsule for accelerated ageing of graphite, which is used in Advanced Gas-cooled Reactors (AGRs), has begun irradiation at NRG’s High Flux Reactor in Petten in the Netherlands. NRG said on 12 September that the irradiation had started two months ahead of schedule. The work is part of Project Blackstone, initiated by an alliance of EDF Energy, NRG, Frazer Nash Consultancy and Atkins in support of ageing management of AGR reactors in the UK. The project will run for four more years and is expected to provide data that can be used in safety cases to support AGR plant operating life extensions. NRG said the online monitoring results demonstrate excellent control of the irradiation conditions.

NRG begins testing special steel for Iter
01 February, 2017
NRG of the Netherlands said on 25 January that it has started irradiation testing Eurofer97 low-activation stainless steel that will be used in the Iter nuclear fusion reactor under construction at Cadarache in southern France.

NRG completes graphite study for EDF Energy
18 January, 2017
The Netherlands-based Nuclear Research and Consultancy Group (NRG) has announced the successful completion of a programme in which EDF Energy studied the effects of irradiation creep on graphite – the process which causes graphite to change in dimensions and properties when irradiated and subjected to a load at high temperature.

IAEA praises Petten management
18 October, 2016
An International Atomic Energy Agency (IAEA) Integrated Nuclear Safety Assessment of Research Reactors (INSARR) mission has said that NRG of the Netherlands has promoted and further developed a strong safety culture at its Petten research reactor based on a mature management system. Following a comprehensive assessment of the safety procedures and regulations at the High Flux Reactor (HFR) from 4 to 11 October, the IAEA team offered recommendations and suggestions to further enhance safety measures at the facility. It noted a "mature management system and good practices" in the areas of training and qualification of staff and safety assessment, and a high level of implementation of previous INSARR recommendations made in 2011

Toshiba withdraws renewal application for ABWR from US NRC
05 July, 2016
Japan’s Toshiba Corporation has withdrawn an application to the US Nuclear Regulatory Commission (NRC) to renew design certification (DC) its Toshiba’s Advanced Boiling Water Reactor (ABWR). The original ABWR DC issued by NRC in 1997 expired in 2012. Toshiba issued an application for DC renewal in 2010, seeking to extend the period of validity following a further design review by NRC. However, falling energy prices in the US mean that Toshiba does not foresee any new opportunities for ABWR construction projects there and sees no need to continue the DC renewal process. Toshiba has accordingly withdrawn the application and says its decision will have no impact on its overall nuclear power business.

Toshiba ends agreements with US CB&I
18 May, 2016
Japan’s Toshiba and US CB&I have agreed to terminate agreements signed in 2010 between Toshiba and Shaw Group related to construction of two Advanced Boiling Water Reactors (ABWRs) at the South Texas Project (STP). Shaw was subsequently acquired by CB&I, which later sold the reactor construction business to Westinghouse, which is part of Toshiba. Earlier in 2008, Toshiba and US utility NRG Energy set up Nuclear Innovation North America (NINA), and applied for a combined construction and operation licence through the STP Nuclear Operating Company, which was granted by the Nuclear Regulatory Commission in February. NINA owns over 92% of the STP newbuild project, and Toshiba has bankrolled the licensing process since NRG withdrew from the project in 2011.
