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.

A family of carbon-fiber-reinforced carbon (and graphite) composites was developed for high-temperature applications. The method of screening for ablation resistance is described. The effects of filament orientation, matrix composition, and heat treatment are related to ablation performance. Between the angles of 15 and 75 deg a general insensitiveness to filament orientation is reported. Materials having a chemical vapor deposited matrix usually performed better than a carbonized organic counterpart. Graphitized materials are more effective than less ordered forms. Process control may be more important than specific composite constituents.
