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.

Magnetoplasma Sail (MPS) is one of the sail propulsion system using the solar wind and suitable for deep space exploration. MPS uses an artificial magnetic field for capturing the solar wind, which is generated by a combination of a coil and a plasma injection. In order to measure thrust of a miniature MPS directory, a parallelogram-pendulum-type thrust stand was developed and installed on MPS ground simulator. In comparison with 0.6 N of Magnetic Sail thrust for 90 mm-magnetosphere, when the magnetospheric size for 115 mm was produced, 4.0 N thrust of the miniature MPS was obtained. The thrust value may include thrust originated with MPD arcjets used for magnetospheric inflation. Our next step of thrust measurement is evaluation of thrust increment for magnetospheric inflation.
