Is tripping of a Nuclear power plant an unlikely incident? This morning 13th of May at 07:13:29 the Swedish Nuclear power plant Forsmark Block 1 with a capacity of 1 GW tripped due to a grid failure. The power ramp started from 8:15 and will be up to full power at approximately 22:00 tonight. Block 2 might also have tripped if it wasn't already out for maintenance until the end of the week. On the 25th of November 2023 the Swedish Forsmark reactor experienced a fault, tripping block 3, with a capacity of 1.2 GW. Resulting in a similar frequency drop reaching 49.6 Hz. Earlier in 2023, on April 26th, it was the two blocks (1 and 2) of the Forsmark plant that were tripped, resulting in a total production loss of 1.0 GW and 1.1 GW, respectively. When adding the disturbances from HVDCs it is close to be every second month that we experience GW-scale faults in the Nordic grid. Hybrid Greentech - Energy Storage Intelligence was supporting the Nordic power system during this fault with our portfolio of grid connected battery systems and electric vehicles.

Interesting for the Australian discussion further two reasons … tripping is a problem for nuclear and when it happens… recovery takes a long time (documented here as 12 hours of ramping)!

Once again, nuclear power shows its ability for flexible production. After a couple of weeks with very low electricity prices in the Nordics, prices rose significantly today 9 october. Thus, the power was regulated up in the four reactors that had been downregulated to a power of 45-75%. At midnight, the power began to be increased in Forsmark 1 and 3 and Ringhals 3 and 4 in order to meet the power demand that arises when the wind declined, the power from the hydrostations were manliy increased befor midnight. In total, nuclear power has increased its output from 4200 MW to 5300 MW, which contributes to maintaining the grid's power balance as well as reducing the price increase. This is a good example of how the different types of power can work together effectively and keep the system stable and fossil-free at all time.

NUCLEAR POWER APPLICATION - EUROPE/SWEDEN

I previously asked the question if tripping of a Nuclear power plant in the GW scale is an unlikely event. Today it happened for the third time (and third power plant) in 4 four weeks.   This morning on the 10th of June at 10:20:35, Forsmark Block 3 had a failure due to a reactor trip of 1172 MW, which made the Nordic system frequency drop to 49.61 Hz. The exact reason is still unknown and the unit is still unavailable.   -On the 3rd of June 2024 was Olkiluoto 3 (OL3) with 1600 MW, suddenly tripped, due to a turbine malfunction. The Nordic system frequency dropped to 49.58 Hz. - On the 13th of May 2024 the Swedish Nuclear power plant Forsmark Block 1 with a capacity of 1 GW tripped due to a grid failure. - On the 25th of November 2023 the Swedish Forsmark reactor experienced a fault, tripping block 3, with a capacity of 1.2 GW. Resulting in a similar frequency drop reaching 49.6 Hz. - Earlier in 2023, on April 26th, it was the two blocks (1 and 2) of the Forsmark plant that were tripped, resulting in a total production loss of 1.0 GW and 1.1 GW, respectively.

Nuclear power is playing an ever-growing role in supplying electric power around the world even as some of its associated prime movers are shrinking in size. Microreactors currently under development in the U.S. are 100 to 1,000 times smaller than conventional nuclear reactors. These units can operate independently from the electric grid or as part of a microgrid to generate up to 20 MW thermal energy that can be used to generate electricity and provide heat for industrial applications. By comparison, the capacity of systems classified as small modular reactors is in the 20 MW to 300 MW range. The first such systems are expected in 2025. https://lnkd.in/gs8gcAuE

Most of the infrastructure of a coal power plant is not different from the one used in a nuclear power plant: they both run turbines using superheated steam to generate electricity. The only difference is the reactor part. Repurposing coal plants into nuclear ones could cut down the cost of a new nuclear plant significantly and help reducing carbon emissions in the near future. Something to think about. https://lnkd.in/g6YtT_uN.

📢 Forsmark has together with the owners taken an important decision to initiate a feasibility study to investigate possible lifetime extension of Forsmark nuclear power plant. 🙌🌍🌱 #nuclearpower #fossilfree #cleanelectricity #decarbonisation

At DLL Solutions we see the revitalization of the Palisades Power Plant in Michigan as an important milestone for nuclear energy in the U.S.. This initiative, supported by a significant loan from the U.S. Department of Energy, highlights the potential for nuclear power to contribute substantially to our energy grid's stability and sustainability. The efforts to reopen a previously decommissioned plant underscore the shifting economic and environmental conditions that make nuclear energy a viable option once again. How do you think the successful restart of Palisades will influence the policies on aging nuclear facilities in other regions? #NuclearEnergy #SustainablePower #EnergyPolicy https://lnkd.in/eyqJCQUk
