A reactor physics teacher is seeking recommendations for books or papers on teaching reactor physics. Traditional texts mentioned include Lamarsh, Henry, and Duderstadt, with older educators favoring analytical solutions and numerical schemes, while younger educators emphasize numerical methods and code development. A suggestion is made for Glasstone and Sesonske's "Nuclear Reactor Engineering," noted for its practical approach and strong section on instrumentation, which may not be present in newer editions. The discussion highlights the importance of specifying the audience and their knowledge level for effective teaching resources.
