Nuclear plants could become smaller, simpler and easier to build in the future, potentially revolutionizing a power source that is increasingly viewed as critical to the transition away from fossil fuels.
New designs called small modular reactors, or SMR in shorthand, promise to speed deployment of new plants as demand for clean electricity is rising from artificial intelligence, manufacturing and electric vehicles.
At the same time, utilities across the country are retiring coal plants as part of the energy transition, raising worries about a looming electricity supply gap. Nuclear power is viewed as a potential solution because it is the most reliable power source available and does not emit carbon dioxide.
Building large plants is very costly and time-consuming. In Georgia, Southern Co. built the first new nuclear reactors in decades, but the project finished seven years behind schedule at a cost of more than $30 billion. READ MORE...
A new report has assessed the feasibility of deploying small modular nuclear reactors to meet increasing energy demands around the world. The findings don't look so good for this particular form of energy production.
Small modular nuclear reactors (SMR) are generally defined as nuclear plants that have capacity that tops out at about 300 megawatts, enough to run about 30,000 US homes. According to the Institute for Energy Economics and Financial Analysis (IEEFA), which prepared the report, there are about 80 SMR concepts currently in various stages of development around the world.
While such reactors were once thought to be a solution to the complexity, security risks, and costs of large-scale reactors, the report asks if continuing to pursue these smaller nuclear power plants is a worthwhile endeavor in terms of meeting the demand for more and more energy around the globe.
The answer to this question is pretty much found in the report's title: "Small Modular Reactors: Still Too Expensive, Too Slow, and Too Risky." READ MORE...
