What is the cost difference between Separation of Isotopes by Laser EXcitation (SILEX) process and Gas centrifuge enrichment for nuclear fuel

Answer

The Separation of Isotopes by Laser EXcitation (SILEX) process offers significant cost advantages over the gas centrifuge method for uranium enrichment in nuclear fuel production. Here's a detailed comparison of the cost differences:

Capital Costs

SILEX:

• Estimated to have the lowest enrichment plant capital costs among current technologies1.

• A SILEX facility with a capacity of 8.75 million SWU (Separative Work Units) per year is estimated to cost about $1 billion6.

Gas Centrifuge:

• A gas centrifuge plant with similar capacity is estimated to cost about $6 billion6.

The capital cost difference is substantial, with SILEX requiring only about one-sixth the investment of a gas centrifuge plant.

Operating Costs

SILEX:

• Annual operating costs for a SILEX facility are estimated to be around $100 million6.

• The process is very energy-efficient, potentially offering significantly lower overall costs1.

Gas Centrifuge:

• Annual operating costs for a gas centrifuge plant range from $100 to $200 million6.

• Modern gas centrifuge plants require about 50 kWh (180 MJ) per SWU3.

While the annual operating costs appear similar, SILEX is expected to be more energy-efficient, which could lead to lower long-term operating expenses.

Cost per SWU

SILEX:

• Estimated cost per SWU is about $306.

• Potentially offers the most cost-effective enrichment process1.

Gas Centrifuge:

• Current commercial cost for enriched uranium is $110 per SWU6.

• Gas centrifuge cost is approximately $15 per SWU4.

It's important to note that the $30 per SWU estimate for SILEX and the $15 per SWU for gas centrifuge come from different sources and may not be directly comparable due to potential differences in calculation methods or time frames.

Overall Cost Impact

Enrichment accounts for almost half of the cost of nuclear fuel and about 5% of the total cost of the electricity generated3. The SILEX technology, with its potential for lower capital and operating costs, could significantly reduce the overall cost of nuclear fuel production.

Additional Considerations

1. Efficiency: SILEX is reported to have a much higher enrichment process efficiency compared to earlier methods, potentially offering significantly lower overall costs1.

2. Environmental Impact: SILEX is expected to have a smaller environmental footprint than centrifuge plants1.

3. Flexibility: SILEX offers greater flexibility in producing advanced fuels for next-generation Small Modular Reactors (SMRs)1.

In conclusion, while exact figures may vary depending on the source and specific implementation, the SILEX process appears to offer substantial cost advantages over gas centrifuge enrichment, both in terms of capital investment and potentially in operating costs. This could lead to significant reductions in the cost of nuclear fuel production and, by extension, nuclear energy generation.

Some smart Alec brought some cheap shares yesterday and overnight in Canada and US. I felt our partner CCJ and another few I hold have been over sold in the crazy news cycles. I was about to buy a house. Holding back to use the cash to take advantage of the short time frame for investments in our sector was a easy choice.

Both sides of GLE are very well covered by this black duck. My suspicion that several new AP1000 announcements are about to occur is not needed for our investments in the sector to be a long term fantastic returns for decades.

Q2

Where are new AP1000 planned

Answer

New AP1000 reactors are planned or under consideration in several countries around the world:

Poland

Poland has selected the AP1000 reactor for its first nuclear power plant. A construction contract is expected to be signed by 2025, with the goal of beginning nuclear power generation in 203313.

Ukraine

Ukraine has made firm commitments for nine AP1000 units46.

Bulgaria

Bulgaria has selected the AP1000 technology for two units at the Kozloduy nuclear site67.

China

China has approved the construction of four new AP1000-based reactors:

• Two at the Bailong Nuclear Power Project in Guangxi Province

• Two at the Lufeng Nuclear Power Plant in Guangdong Province

This brings the total number of operational and approved AP1000-based reactors in China to 1646.

Other Potential Locations

The AP1000 technology is also under consideration in:

• Multiple sites in Central and Eastern Europe

• The United Kingdom

• India

• North America46

Netherlands

Westinghouse has signed a contract with the Dutch government to conduct a technical feasibility study for deploying two AP1000 reactors at the Borssele nuclear power station7.

Finland and Sweden

Westinghouse and Finnish utility Fortum are exploring the possibility of developing and deploying AP1000 reactor projects in these countries3.

By the end of this decade, Westinghouse projects that there will be 18 units based on AP1000 technology in operation globally4.

Where are new AP1000 planned

When will America add more ap1000s

Answer

As of February 2025, the United States has recently completed two AP1000 reactors at the Vogtle Electric Generating Plant in Georgia, with Unit 3 entering commercial operation in July 2023 and Unit 4 in April 20244. While there are no concrete plans for immediate construction of additional AP1000 reactors in the U.S., several developments suggest potential future additions:

Ongoing Discussions

Westinghouse, the developer of the AP1000 design, is reportedly in discussions with more than one North American utility about potentially adding AP1000 reactors3.

Reconsidering Large Nuclear Reactors

A recent study from February 2025 proposes a scenario to build 300 new large reactors in the U.S. over 50 years, using the AP1000 as an example. This plan suggests starting construction on 6 reactors every year, with the goal of having 36 large reactors operating by 20351.

Potential Sites

An analysis by the Idaho National Laboratory has identified:

• 18 promising sites for near-term AP1000 deployment

• 29 additional sites with potential for AP1000 deployment

• 10 sites currently unsuitable, but 9 of these could potentially host AP1000s in the future with changes to state policy2

Renewed Interest in Canceled Projects

As of January 2025, there are reports that Santee Cooper is exploring construction and financing partners to finish two previously canceled AP1000 reactors at the Virgil C. Summer Nuclear Generating Station in South Carolina. The growing need for electricity to power data centers is cited as a driving factor for this renewed interest6.

While these developments suggest potential for future AP1000 additions in the U.S., it's important to note that no firm commitments or construction starts have been announced as of February 2025. The timeline for any new AP1000 reactors in America will depend on factors such as regulatory approvals, financing, and utility decisions in the coming years.
