Direct cycle-type atomic power plant with means for suppressing transfer from a liquid phase to a vapor phase of radioactive nitrogen oxides

摘要

A direct cycle type atomic power plant provided with a means for suppressing transfer of radioactive nitrogen compounds generated by nuclear reaction in the core from the reactor water to steam, where an increase in the dose rate in the main steam system and the turbine system due to carry-over of radioactive nitrogen atom, 16N, generated in the core can be suppressed, and the radioactivity therein can be reduced.
