Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

General Atomics has supported the dynamic hohlraum experiment series with the production of double-shell targets filled with deuterium, xenon, and neopentane gases. Production of a double-shell target is a process by which multiple subassemblies are fabricated, assembled, and characterized in a planned sequence. An inner capsule assembly is produced with a SiGDP conversion glass capsule stalk mounted and attached together with glass fill tube and laser-cut beryllium disk. An outer CH mandrel with a permeation barrier is then machined and each subassembly fitted together. Challenges include aligning the inner and outer glass capsules as well as filling the inner void space with known gas quantities. Information describing how we assemble the target, new hardware designed to complete the gas fills, and characterization techniques to analyze the assembly will be presented.
