Facility scheduled to begin generating power for grid in 2021 The first of two reactors at the Shidaowan HTR-PM nuclear plant has achieved first criticality. Courtesy China Huaneng. The first of the two high-temperature gas-cooled reactors at the Shidao Bay demonstration HTR-PM plant in Shandong province, eastern China, attained reached first criticality on Monday, China National Nuclear Corporation said.

The No.1 reactor at the plant, also known as at Shidaowan, achieved first criticality at 09.35 local time on 12 September, CNNC announced. It said the milestone was reached 23 days after the start of fuel loading.

Operators will now perform zero-power physical tests to verify the core and control rod performance and the functionality of monitoring equipment.

The unit is scheduled to be connected to the electricity grid before the end of this year and to begin generating electricity for the grid in 2021.

The gas-cooled HTR-PM is a Generation-IV reactor design with twin reactor modules of 100 MW each driving a single 200-MW steam turbine.

Plant could play ‘major role’ in clean hydrogen production at industrial scale The IMSR is one of three SMR plants under consideration for deployment at the Darlington nuclear station in Canada.

Canada-based generation IV reactor developer Terrestrial Energy has upgraded its integral molten salt reactor (IMSR) nuclear power plant design in response to utility requirements.

The company said the upgrade increases the cost-competitiveness of the IMSR400 and means it has the efficiency, economics and flexibility to play a major role in the clean energy transition including the production of clean hydrogen at industrial scale.

The IMSR400 is one of three small modular reactor power plant designs under consideration for deployment at Ontario Power Generation’s Darlington nuclear power station. The others are designs by GE Hitachi and X-energy. The IMSR400 is one of two Generation IV technology candidates and the only Canadian technology candidate.

The plant is a proprietary design drawing on Generation IV reactor technology developed and demonstrated over many decades. Using molten salt reactor technology, the IMSR400 generates electric power 50% more efficiently than conventional nuclear power plants that use water-cooled and water-moderated reactor technology. According to Terrestrial Energy, with this 50% efficiency improvement, the IMSR400 has a reduced capital requirement and waste footprint, and improved economics per kWh of electricity for new nuclear power plants.

Nuclear energy, as an asset class, has the potential to report well against a wide range of Environmental, Social and Governance (ESG) data collection and accounting metrics, according to a new report from the Generation IV International Forum (GIF). This should allow nuclear energy to be considered as an investable asset class, thereby allowing nuclear companies and projects to access climate finance.

The governments of Australia and the UK have signed a letter of intent (LoI) to establish a partnership on low emissions solutions including clean hydrogen and small modular reactors (SMRs). Meanwhile, the Australian Research Council (ARC) has awarded funding to a newly launched project to develop fuel for hydrogen-boron fusion which its participants say has the potential to re-establish Australia as a leader in fusion research and clean energy technology.

Ministers investing £170m in project to build first unit by early 2030s Courtesy Wikipedia. The UK’s plan to have the latest nuclear technology up and running within the next decade has moved a step closer with publication of a call for evidence which sets out the government’s suggested approach to building the first advanced small modular reactor demonstrator.

The government said it will specifically explore high temperature gas reactors (HTGRs) as the most promising model for the demonstration programme, which ministers are investing £170m into delivering by the early 2030s.

The proposed HTGR plants are smaller than conventional nuclear power stations, more flexible, and could be built at a fraction of a cost, the Department for Business, Energy and Industrial Strategy said.

As well as creating electricity to power homes on the grid, the UK is hoping HTGRs will also be able to generate low-carbon hydrogen, or “green” hydrogen. In addition, thanks to also generating extremely high temperature heat, they could help decarbonise industry and potentially power district heating networks by the 2040s.
