France awards grants for research and development of molten salt reactors
27 March, 2024
Two nuclear start-ups, Stellaria and Thorizon, each in consortium with Orano, have been selected by the French government to receive funding through the France 2030 national investment plan to develop molten salt reactors. Each consortium has been awarded a €10m ($10,8m) grant. The two projects are the result of a collaboration of several months bringing together these three companies with the aim of developing a European molten salt reactor (MSR) sector.

Constellation completes acquisition of stake in Texas NPP
07 November, 2023
US power utility Constellation has completed its acquisition of NRG Energy Inc’s 44% ownership stake in the South Texas Project Electric Generating Station (STP).

Full financing approved for Pallas reactor
21 September, 2023
The Netherlands government will fully finance the cost of Pallas research reactor at Petten. Minister of Health, Welfare & Sport Ernst Kuipers has confirmed full financing for the construction of the reactor. The positive decision was expected. In February, the Nuclear & Radiation Protection Authority (ANVS - Autoriteit Nucleaire Veiligheid en Stralingsbescherming) granted a construction licence for the reactor and Rijkswaterstaat issued the Water Act permit for the intake and discharge of cooling water.

Constellation acquires ownership stake in South Texas Project
06 June, 2023
US power company Constellation is acquiring NRG Energy’s 44% ownership stake in the South Texas Project Electric Generating Station (STPEGS). The 2,645 MWe two-unit plant is located about 90 miles southwest of Houston. The transaction is valued at $1.75bn, with an effective purchase price of $1.4bn after taking into account tax benefits to Constellation. The transaction will be financed with a combination of cash and debt. The South Texas Project is one of the newest and largest NPPs in the USA with a good track record for safety and reliability.

COVRA receives final approval for construction of new radwaste storage facility

Construction licence issued for Pallas reactor
16 February, 2023
The Netherlands Nuclear and Radiation Protection Authority (ANVS - Autoriteit Nucleaire Veiligheid en Stralingsbescherming) has granted a construction licence for the Pallas reactor at Petten, in the municipality of Schagen. Rijkswaterstaat has also issued the Water Act permit for the intake and discharge of cooling water. This means the permit under the Environmental Law (General Provisions) Act for the construction of the buildings and cooling water pipes will also come into force.

Preparatory work begins for construction of Pallas reactor
23 November, 2022
Preparatory works have started to enable realisation of the construction of the Pallas reactor in the Netherlands. The Pallas Research Reactor will be built at Petten to replace the existing 45 MWt High Flux Reactor (HFR) that began operation in September 1960. Since then its use has shifted from nuclear material testing to basic research and the production of medical radioisotopes. HFR, operated by NRG on behalf of the European Union’s Joint Research Centre, has provided about 60% of European and 30% of the world's use of medical radioactive sources. The new 55MWt tank-in-pool type Pallas reactor will be able to deploy the neutron flux more efficiently and effectively than the HFR.

Netherlands government supports construction of Pallas reactor
22 September, 2022
Dutch Minister of Health, Welfare and Sport Ernst Kuipers has announced that money has been allocated for the construction of the Pallas reactor at Petten, in The Netherlands. The ministry reserves €30 million ($29.5m) for the project this year and €129 million a year from next year, NRG said.

Thorizon raises funds for waste-burning thorium molten salt reactor

Petten starts research into fuel cladding for EDF
29 July, 2022
Work has begun at NRG’s High Flux Reactor in Petten, the Netherlands, to investigate material for fuel cladding tubes, according to NRG. In order to match the supply of electricity to fluctuating energy demand in the future, new fuel cladding tubes will have to be designed as temperatures will fluctuate. In December 2020, EDF and NRG started a collaboration and during the past 18 months preparations have been completed for the concept design, final design and fabrication of an irradiation installation.
