PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

A safety instrumented system design guided by the International Electrotechnical Commission (IEC) standard IEC/ISA 61511 has been developed to ensure personnel protection from direct radiation and magnetic field hazards identified for the National Spherical Torus eXperiment–Upgrade (NSTX-U) fusion experiment at the Princeton Plasma Physics Laboratory. A layer of protection analysis was performed to develop the performance requirements of the system. A design was developed that incorporated three independent protection layers including configuration-managed safeguards (for electrical hazards), a trapped key system, and a dual chain redundant safety instrumented system. Extensive value engineering was undertaken to supplement existing infrastructure to be compliant with current industry standards and best engineering practices. The development and design of the safety instrumented system is presented.
