Small Modular Reactors

These conference proceedings present a review of nuclear power developments in the past, present and future, including pressurized water reactors (PWR), small modular reactors (SMR), and advanced reactor designs. The authors position the evolution of nuclear technology in the context of the search for a clean energy system with resilience.
This report focuses on nuclear energy as one pathway to meeting the twin challenges of alleviating energy poverty and minimizing greenhouse gas emissions. Part 1 outlines the state of nuclear power deployment in sub-Saharan Africa. Part 2 gives an overview of what the challenges of deploying nuclear power are likely to be. And Part 3 describes advanced nuclear technology and how it could increase the likelihood of nuclear development.

This journal article presents a study to evaluate the status of small modular nuclear reactors and International Atomic Energy Agency (IAEA)-assisted desalination projects for the Middle East and North Africa region. The authors (1) discuss the potential of the Kingdom of Saudi Arabia for adopting nuclear reactors and coupled nuclear reactor desalination, (2) examine the theoretical and computational techniques that could be best suited for adopting nuclear desalination and (3) discuss the techno-economics analysis of CAREM and SMART nuclear reactors with cost estimation.

In these PNAS proceedings, the authors use interviews with 16 experts to evaluate two small modular reactor (SMR) designs based on engineering-economic assessment experiences. They provide estimates of the overnight cost and construction duration for five reactor-deployment scenarios that involve a large reactor and two light water SMRs.

This report quantifies greenhouse gas (GHG) emissions from the industrial sector and identifies opportunities for non-GHG-emitting thermal energy sources to replace the most significant GHG-emitting U.S. industries based on targeted process-level analysis of industrial heat requirements. The intent is to provide a basis for projecting opportunities for clean energy use; doing so provides a prospectus for small modular nuclear reactors (including nuclear-renewable hybrid energy systems), solar industrial process heat and geothermal energy, according to the authors.

This journal article highlights the advantage held by first-mover technologies in the energy industry, which presents a barrier to newer, cleaner technologies unless sufficient efficiency and cost gains can be demonstrated. According to the authors, nuclear fission and solar photovoltaics provide a test case for understanding the value of "going small" in order to move innovation forward.
