Literature Review: Fission problem for Nuclear

This “Ten Problems for Nuclear in the 2020s” booklet identifies ten relevant areas from very recent contributions put forward at academic level in the form journal articles, conference proceedings and students theses. Ten freely accessible internet references have been selected for each area and direct links are provided at the end of each chapter for own consultation. Our selected references do not intend to mirror ranking indexes nor establish novel classifications. On the contrary, they are meant to represent peer-reviewed, diverse and scientifically-sound case studies for vertical dissemination aimed at non-specialist readers. They will also be able to scoop even more references through the bibliography that is reported at the end of each selected reference.

Without further ado, these are the ten problems that we are going to introduce in this booklet:

  1. cost, 
  2. climate change,
  3. fission,
  4. fusion,
  5. waste,
  6. security,
  7. proliferation,
  8. accidents,
  9. applications,
  10. outer space.

Each problem has its own dedicated chapter made of an introductory section, a short presentation of the ten selected references and a conclusions section.

The final chapter of this booklet will report the conclusions from each chapter again in order to provide a complete executive summary.

3 Fission

THE PROBLEM — Significant progress in the understanding of the fission process within a microscopic framework has been recently reported. Increasing complexity of design, construction and operation of Light Water Reactors may create unexplored paths for accidents. IAEA Member States considering low-carbon energy strategies are assessing the adoption and deployment of small modular reactors. Policy makers should also accelerate the demonstration and deployment of innovative nuclear technologies.

CONCLUSIONS — Experimentally one cannot isolate and measure properties of post-scission fission fragments, and any full model will have to include simulations. The original competences for the design and ensuring the safety of reactors may have a marginal role. Savings from learning and small modular construction will be probably inadequate to compensate for the economic challenges resulting from the lower generation capacity. There is a lack of a standardized approach in the evaluation of the economic and financial performances of small modular reactors, making a proper comparison impossible in most of the cases. All Gen IV concepts have significant flexibility features to meet emerging, energy market needs in terms of load following, scalability and heat generation, as well as hydrogen production. Some observers and interest groups have cast doubt on the potential safety, affordability, and sustainability of Gen IV advanced reactors. The development of advanced materials solutions including advanced materials and processes is moving much faster than the actual ability of the nuclear industry to introduce them into design codes. The technology readiness level of the Thorium-based Molten Salt Reactors, at early demonstration stage, implies that all major conceptual issues are solved and only practical engineering issues remain. The design of compact power plants with a small core size (less than 2.5 cm) and high energy density (from 0.7 to 70 MW / kg of fuel) is not yet feasible.. US DOE Microreactor Program is undertaking some of the most important and challenging research and development efforts to accelerate microreactor deployments by mid-2020s.
