摘要： Passive cooling systems and methods, in which an infinite cooling circulation occurs by itself while cooling water is passively circulated without separate operation and control of an operator and supply of an external power source in the event of an abnormality in a nuclear reactor. The passive cooling system includes an energy release space; an energy absorbing space to which a pressure in the energy release space is transferred; an energy transfer space which absorbs and cools heat transferred from the nuclear reactor vessel as the cooling water; an emergency cooling flow passage for transferring heat to the energy transfer space; a reactor thermal insulation vessel; a pressure equalization pipe to transfer water vapor and pressure in the reactor thermal insulation vessel to the energy absorbing space; and a coolant spray pipe for flowing pressurized cooling water by the pressure equalization pipe to the energy transfer space.

摘要： The present invention relates to a composition for inhibiting the growth of cancer stem cells and a use thereof. When treated with the EMP3 inhibitor, cancer stem cells expressing ALDH1 decrease in self-renewal potential, invasiveness, and migration ability and thus are restrained from growing, whereby cancer having stemness properties, which are resistant to conventional anticancer therapies, can be effectively treated.

摘要： The present disclosure relates to a method of removing a radioactive structure from a nuclear power plant. The method includes flattening at least a portion of an outer surface of a drilling portion of a wall of a nuclear reactor vessel when the portion of the outer surface is uneven, wherein the radioactive structure is buried in the wall and the drilling portion is adjacent to the radioactive structure, installing a drilling device in the flattened drilling portion and performing a drilling operation, extracting the radioactive structure from the wall, and cutting the extracted radioactive structure and storing pieces of the cut radioactive structure in a shielding container.
