摘要： PROBLEM TO BE SOLVED: To reduce the exposure of workers to radiation by reducing the transiting amount of radioactive nitrogen to a turbine system in a BWR power plant.

Nitrogen compounds are oxidized by oxidizing radicals, such as OH, produced on surfaces of the injected titanium oxide and turned into a form stable in liquid phase, and the transiting amount of radioactive nitrogen to the turbine system is reduced. This lowers doses in the turbine system, and reduces the exposure of workers to radiation.
