Remembering Joseph M. Hendrie
Joseph M. Hendrie
To those of us who knew Joe, even prior to his appointment as chair of the Nuclear Regulatory Commission, it is an understatement to say that he was a larger-than-life member of the nuclear science and technology enterprise. He was best known to the broader community for two major accomplishments: the design and construction of the High Flux Beam Reactor (HFBR) at Brookhaven National Laboratory and the creation of the standard review plan (SRP) for the U.S. Atomic Energy Commission.
In addition to the products of these endeavors becoming major fundaments to their respective communities, they were uniquely Joe. The safety analysis report for the HFBR was written essentially single-handedly by him. This was true of the SRP as well, which became the key safety review document for the NRC as it performed safety reviews for the growing number of power reactor applications in the United States. His deep technical knowledge of nuclear engineering and his extraordinary management skills made this possible.

The sensitivity of coupled neutron-photon transport simulations to the underlying nuclear data is studied for oil well logging applications using the Monte Carlo radiation transport code MCNP4C. Results obtained with the JEF-2.2, ENDF/B-VI.5, and JENDL-3.2 data libraries reveal large discrepancies, confirming immediately the importance of well-established nuclear data. In order to refine this conclusion, the impact of several nuclides is determined by varying their neutron and photon total cross sections. As a next step, neutron cross sections and photon production cross sections are modified per reaction channel to identify the most important nuclear reactions playing a role in C/O logging. The influence of neutron and photon angular distributions is studied as well. The outcome of this analysis is a list of nuclear reactions that have a significant impact on borehole logging tool simulations in different environments and, therefore, would deserve much attention in the construction of a new library for oil well logging.
