Heysham Nuclear Power Station to Close
The closure of the Heysham nuclear power plant is coming just after the UK government approved the Hinkley Point C project, which carries a $23.8 billion price tag and a strike price guarantee. The shutdown is scheduled to happen every three years. This will not affect the supply of electricity, and will include camera inspections of the reactor and the installation of new plant equipment. The biggest project is replacing two large gas circulators.
Heysham 2 is scheduled to decommission in 2023
The Heysham nuclear power stations have been subject to concerns about proximity. The Heysham 2 area is approximately 80 acres, and can no longer meet the criteria for semi-urban development. The cooling water required for the reactors is immense, requiring up to 50m3 of water per second. The Heysham nuclear power stations are located on the coast, which makes the decommissioning process all the more challenging.
Heysham 2 is due to be decommissioned in 2023. The Heysham plant has three units that produce approximately 1230 MW each. Heysham 2 was commissioned in 1988. The Heysham plant will be closed in 2023. The Torness and Sizewell B plants are also scheduled to close in the next decade. The Heysham nuclear power stations will be decommissioned in 2023 and 2035 respectively.
The defueling process will begin in 2022 for Dungeness B and Hunterston B. It will take until 2025 or 2026 for all three facilities to be fully decommissioned. Once defueling has finished, EDF Energy will transfer ownership to the Nuclear Decommissioning Authority and Magnox Ltd will complete the decommissioning process. These decommissioning projects are vital to the country's economic stability and national security.
The government has a guarantee to back the Nuclear Decommissioning Fund. The Fund must be able to cover the total costs of decommissioning. It contributed PS5.1 billion ($6.8bn) in 2020, and requested PS5.6 billion in March 2021. The Fund's assets have reached PS14.8 billion at the end of March 2021. It is hoped that the Fund's investments will continue to increase in value to cover decommissioning costs over the next several decades.
Heysham 2 has two advanced gas reactors
Heysham 2 is a nuclear power station with a net electrical output of 1,210 megawatts, which is sufficient for supplying up to 2.5 million homes. It has two advanced gas reactors, each of which can produce enough electricity to power up to three cities the size of Liverpool during peak demand. The plant was built by the Central Electricity Generating Board and is operated by EDF Energy.
One of the main benefits of these reactors is their low carbon emissions. The power generated from Heysham 2 can power all of the UK for five years. In fact, it is more energy efficient than its light water counterpart, which must be shut down during refueling. Another benefit of these reactors is that they can be refueled while online, making them more efficient and productive. Both Heysham units have advanced gas reactors and will continue to produce energy for decades to come.
The Heysham nuclear power station is located in Lancashire, England. It is divided into two separate stations. Heysham 1 is an advanced gas-cooled reactor, and Heysham 2 is an advanced liquid-cooled reactor. Both units generate power sufficient for almost two million homes in Northwest England. The plant employs around 1,100 people, including 400 contracting partners. The two advanced gas reactors in Heysham 2 are very efficient, providing reliable, clean energy.
The Heysham 1 and Heysham 2 nuclear power stations are both operated by EDF Energy. Both units are expected to operate for another four decades. Heysham 2 is due to break its own record in February 2017 and achieve 996 days of uninterrupted operation. However, it is scheduled to shut down for scheduled maintenance in April 2017.
In December 1997, seaborne salt affected the grid connection in Heysham 2 and Torness. However, it was able to re-connect after the shutdown. The modifications were successfully completed and the new control rod tests confirmed that the activity of the core was significantly reduced. These new tests show that the control rods should last the planned thirty years of the stations. However, the delay for the second two reactors was not significant.
The safety case has a critical role in design assessment. It details the key features of the safety case and describes design problems that arose during construction. The safety case highlights the challenges encountered during construction, which were overcome with minimal impact on the programme. The UK's probabilistic safety guidelines state that the probability of accidents is 10?/year, with individual faults contributing to the risk. Higher frequency faults, however, are acceptable for lower releases.
Heysham 2 has produced more than 280 terawatt hours of zero-carbon electricity
Two nuclear power stations in the UK are due to close, Heysham 1 and Heysham 2. Both are still producing power, but are well past their anticipated generating life. In fact, Heysham 1 is already operating beyond its 25-year lifespan, and is expected to attract one million visitors per year. It is expected to create hundreds of jobs and generate considerable interest both nationally and internationally. Whether the closure of these nuclear power stations will affect the local economy is unclear, but it's likely that the plants will continue to contribute to the local economy for decades to come.
Despite the potential job losses, it's important to note that the nuclear power station will stop generating electricity after 2028. This is the reason why the operational life of the plant was extended seven years to 2030. This extension is needed to meet the demand for a constant base load on the electricity grid. After that, the station will move into defuelling and decommissioning.
The UK nuclear industry is in a transitional phase and needs the energy transition to be as efficient as possible. This is where the Heysham 2 plant and Torness nuclear power station will come into their own. Unlike many nuclear power stations, the Heysham 2 plant can generate electricity without any interruption. In fact, this is the longest running nuclear station in the world. In 2016, it broke the world record for continuous nuclear power generation without any shutdowns. Then, in September 2016, Heysham 2 went offline for maintenance, but it had been online for over 940 days. The three other nuclear power plants - Heysham 1 and Hartlepool - will be closed by March 2024, but the Sizewell B plant will be operational beyond that date.
The closure of Heysham 2 in Lancashire was widely expected to end in March 2028. But the closure date was delayed after the operator EDF announced that it had decided to extend the operating life of Torness by seven years, to 2028. But a seven-year extension of the Heysham II and Torness nuclear power stations was announced in February 2016.
