IRPhEP Handbook cover

The International Handbook of Evaluated Reactor Physics Benchmark Experiments was prepared by a working party comprised of experienced reactor physics personnel from Argentina, Belgium, Brazil, Canada, China, France, Germany, Hungary, Italy, Japan, Republic of Korea, Russian Federation, Slovenia, Switzerland, United Kingdom, and the United States. The handbook contains reactor physics benchmark specifications that have been derived from experiments that were performed at various nuclear experimental facilities around the world. The benchmark specifications are intended for use by reactor physics personal to validate calculational techniques

The 2011 Edition of the International Handbook of Evaluated Reactor Physics Experiments contains data from 53 different experimental series that were performed at 31 different reactor facilities. Forty-eight of the 53 evaluations are published as approved benchmarks. The remaining 5 evaluations are published as DRAFT documents only. Draft documents have been reviewed by the IRPhEP Technical Review Group (TRG); however, all action items could not be completed or reviewed in time for the final publication or, in most cases, the TRG felt it necessary to review the revised evaluations before giving final approval. The Handbook is organized in a manner that allows easy inclusion of additional evaluations, as they become available. Additional evaluations are in progress and will be added to the handbook periodically.
