Have you ever wondered what the inside of a nuclear reactor looks like?

NEI (Nuclear Engineering International has published more than 100 reactor wallcharts. From the Fermi Pile (#2) to the EPR (#98), the series of 100 charts covers the entire history of the nuclear industry, worldwide. Every major type of reactor technology is covered: PWRs, BWRs, PHWRs, FBRs, HTGRs, Magnox, and others (remember the organic moderated reactors)?

Not all the designs were eventually built. Some of the more interesting non-starters include the marine-based Atlantic Generating Station, #59, and the Argentinian Argos PHWR-380, #92, and the nearly-completed Alto Lazio 1&2 in Italy (#84). Some are still planned (SAFR, #91, PRISM, #94) or under construction, such as Korea’s Shin-Kori 1&2 (# 101).

    • These are great, I have found similar drawings helpful when performing a peer review on a plant design other than those I have worked at particularly PHWR’s and BWR’s. Also great for use during training when explaining something about a reactor type that the participants are not familiar with.

  3. The University of New Mexico has kept a catalog of all these beautiful drawings. You can peruse their archives for free:
