TerraPower circles 2023 for Natrium construction permit

TerraPower hopes to apply for a construction permit in August 2023 and an operating licence in March 2026 for its Natrium fast reactor, according to a regulatory engagement plan (REP) it has sent to the US Nuclear Regulatory Commission.

CORDEL: Regulatory harmonisation needed to speed SMR deployment

CORDEL: Regulatory harmonisation needed to speed SMR deployment

For small modular reactors to play their part in the clean energy transition, it is crucial that vendors and regulators engage early to clarify the degree of design maturity required to start the licensing process, according to a new report published today by World Nuclear Association. National regulators should collaborate through bilateral and multinational agreements on design and safety reviews, share technical reviews, establish common positions on safety criteria, and make appropriate use of existing reference SMR design reviews to streamline SMR licensing processes, it says.

Russia starts building lead-cooled fast reactor

Russia starts building lead-cooled fast reactor

Russian nuclear fuel manufacturer TVEL has announced the start of construction of a 300 MW nuclear power unit enabled with the innovative BREST-OD-300 lead-cooled fast reactor at the site of the Siberian Chemical Combine, in Seversk. The reactor will run on mixed uranium-plutonium nitride fuel, specially developed for this facility as the "optimal solution" for fast reactors.

Pilot Natrium plant to be built in Wyoming

Pilot Natrium plant to be built in Wyoming

Plans to construct a Natrium reactor demonstration project at a retiring coal plant in the US state of Wyoming were announced yesterday by TerraPower, PacifiCorp and Wyoming Governor Mark Gordon. The companies are evaluating several potential locations in the state for the plant, which will feature a 345 MWe sodium-cooled fast reactor combined with a molten salt energy storage system that can boost the system's output to 500 MWe for more than five-and-a-half hours when needed. They expect to announce the selected site by the end of 2021.

NRC fees must change to enable innovation, says panel

NRC fees must change to enable innovation, says panel

As multiple advanced reactor vendors enter the licensing process to build first-of-a-kind demonstration projects, issues with the US Nuclear Regulatory Commission's current user fee cost recovery model could slow innovation and raise regulatory costs, according to a report published yesterday by the Nuclear Innovation Alliance (NIA). Reliance on applicant fees limits the ability of the NRC to hire and train staff ahead of expected applications, reducing regulatory efficiency, the report says.

UK SMR to start regulatory process this autumn

UK SMR to start regulatory process this autumn

The UK SMR consortium, led by Rolls-Royce, has announced the latest design and an increase in power - from 440 MW to 470 MW - of its "compact" nuclear power station. The "refreshed design" features a faceted aesthetic roof; an earth embankment surrounding the power station to integrate with the surrounding landscape; and a more compact building footprint, the British engineering company said.

Hunterston B cleared for six months of operation

The UK's Office for Nuclear Regulation has today provided EDF with permission for Reactors 3 and 4 at the Hunterston nuclear power plant in North Ayrshire, Scotland to return to service for a limited period of operation. This will be the power station’s final period of operation before moving into the defueling phase.

Russia transports first RPV for Kursk VVER-TOI plant

The Volgodonsk branch of Russia's AEM-Technology JSC has dispatched the first-ever reactor pressure vessel for the VVER-TOI (typical optimised, with enhanced information) reactor design. The RPV is being transported to the construction site of the Kursk II nuclear power plant, which will be the first to use the new design. Hydraulic testing of the RPV for the first Kursk II unit was completed in December last year.

Design anomaly found in Flamanville EPR nozzles

Design anomaly found in Flamanville EPR nozzles

EDF notified France's nuclear safety regulator, the Autorité de Sûreté Nucléaire, on 3 March of a significant event concerning a design anomaly on three nozzles of the main primary system of the EPR reactor under construction at Flamanville. The concerned nozzles were produced in 2011 based on a 2006 design file. The regulator has asked EDF how it plans to deal with this anomaly.
