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.

Until the recent experimental campaign in 2006, all the neutral beam systems on the DIII-D tokamak injected power with the momentum in the same direction as the usual plasma current ("co-injection"). A major modification made during the April 2005-March 2006 shutdown period rotated one of the two-source beamlines to allow injecting power with the momentum opposite that of the plasma current ("counter-injection"). This modification provides the capability of injecting up to 10 MW of neutral beam power with zero net momentum input to the plasma. Decoupling the injected momentum and power opens a previously inaccessible parameter space for experiments that study the effect of rotation on various plasma instabilities, transport, and operational scenarios.Rotating the 5 MW neutral beamline presented significant technical challenges. The beamline and several major subsystems required extensive dismantling and rebuilding, and a careful alignment of the ion sources was required to document the new injection paths. We present a summary of the tasks required for the beamline rotation, describe major technical issues addressed, and discuss the advantages of the new configuration.
