Singapore's Nuclear Energy Preparations Enter a New Phase: No Decision Yet to Build a Plant, Why Build Judgment Capacity First

When a country prepares to develop nuclear power, the first thing to appear may not be a reactor order. It may instead first establish a research team to analyze technical options, train regulatory personnel, and study how to handle spent fuel decades from now. This work is far from the construction site, yet it determines whether the country can understand the proposals put forward by suppliers in the future and whether it has the capacity to bear the corresponding responsibilities. On October 30, the VTT Technical Research Centre of Finland and the Singapore Nuclear Research and Safety Institute (SNRSI) under the National University of Singapore announced a five-year cooperation arrangement covering reactor technology assessment, safety analysis, radioactive waste and spent fuel management, and other areas.

Recycled chloride salt fuel prepares to enter research reactor: Can spent fuel become a resource, and what data must be obtained first?

Turning nuclear material into another kind of fuel. Idaho National Laboratory (INL) announced on November 2 that it will lead the IMPACT project to fabricate and test chloride salt fuel containing recycled transuranic elements. The project has received $7 million in support from the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) and plans to use nuclear materials already available at the laboratory to complete fabrication and property testing, and to conduct irradiation in the Advanced Test Reactor (ATR). This research advances the improvement of spent fuel utilization to a specific question: after recovered materials form new fuel, how exactly do they change in the reactor environment? Moltex participates in modeling and design-related work.

Repair Completed on Damaged Power Supply Facilities Near Zaporizhzhia Nuclear Power Plant, Reducing Risk of External Grid Power Outage

The International Atomic Energy Agency (IAEA) officially announced on October 23 local time that emergency repair work has been successfully completed on the previously damaged critical external power supply infrastructure near the Zaporizhzhia Nuclear Power Plant. The repair has significantly improved the operational stability of the plant's sole remaining external transmission line, alleviating to a certain extent the severe safety risk of the plant once again experiencing a complete station blackout. The power facility repaired in this operation is located in the switchyard area of the Zaporizhzhia Thermal Power Plant, approximately two kilometers from the Zaporizhzhia Nuclear Power Plant site. This critical electrical hub was attacked and severely damaged during military conflict in September this year...
