Integral Fast Reactor/Debate Guide

Readiness of this design

The National Academy of Sciences has just come out with a new report Laying the Foundation for New and Advanced Nuclear Reactors in the United States. They have concluded that this design needs a lot more work.
From the Summary:
P.1) demonstrations of advanced nuclear designs are not expected until the late 2020s or early 2030s,
P.2) SFRs and HTGRs will need to address supply chain and high-assay low-enrichment uranium (HALEU) issues and operational reliability, which have impacted those designs in the past.
... for example, reactor core materials and cladding.
From Chapter 2, Finding 2-5) ... More mature concepts, such as ... small modular sodium fast reactors, and ... might be technically ready for demonstration by the end of this decade.
