International Reactor Physics Handbook Database and Analysis Tool (IDAT)

The IRPhEP Database and Analysis Tool (IDAT) was first released in 2013 and is included on the DVD. This database and corresponding user interface allows easy access to handbook information. Selected information from each configuration was entered into IDAT, such as the measurements performed, benchmark values, calculated values and materials specifications of the benchmark. In many cases this is supplemented with calculated data such as neutron balance data, spectra data, k-eff nuclear data sensitivities, and spatial reaction rate plots.

IDAT accomplishes two main objectives:

  1. Allow users to search the handbook for experimental configurations that satisfy their input criteria.
  2. Allow users to trend results and identify suitable benchmarks experiments for their application.

IDAT provides the user with access to several categories of calculated data, including:

IDAT is actively being developed. Those approved to access the online version of the handbook will also have access to an online version of IDAT. As May 2013 marks the first release, IDAT may contain data entry errors and omissions. The handbook remains the primary source of reactor physics benchmark data. Please send any bugs or suggestions to .
