摘要： Disclosed herein is a reference electrode including an electrolyte containing an optically-active material, including: an electrode body provided at an end thereof with an electrolyte separation membrane and charged therein with an optically-active material and an electrolyte solution; an inner electrode disposed in the electrode body to be immersed in the electrolyte solution; and an absorbance measurement probe for transmitting light to the electrolyte solution and collecting reflected light waves, which is disposed in the electrode body to be immersed in the electrolyte solution. Since the concentration of an electrode reaction material, such as Cl−, in the electrolyte is calculated using the absorbance of the electrolyte solution containing the optically-active material, the change in potential of the reference electrode can be properly corrected even when the reference electrode is exposed to a test environment for a long period of time and thus the concentration of the electrolyte changes. Thus, the functions of the reference electrode can be maintained for a long period of time, thereby rapidly monitoring the abnormal states caused by damage to the reference electrode.

摘要： Disclosed is a coolant with dispersed neutron poison micro-particles, used in a supercritical water-cooled reactor (SCWR) emergency core cooling system. Since the neutron poison micro-particles are uniformly dispersed in the coolant of the emergency core cooling system for a long period time, their fluidity is not lowered even though the polarity of water is changed in a supercritical state. Therefore, the neutron poison micro-particles absorb neutrons produced from nuclear fission in a nuclear reactor core. Accordingly, the neutron poison micro-particles can be appropriately used as a means for controlling neutrons and stopping a nuclear reactor in the SCWR emergency core cooling system.

摘要： A method for treating neutrons generated from spent nuclear fuel is provided, which includes a step of injecting neutron absorption material into the spent nuclear fuel storage water in which cooling function is lost. Accordingly, as the neutron absorption material in the form of particles is injected into a spent nuclear storage pool missing cooling function and deposited on the surface of the spent nuclear fuel, the possibility reaching nuclear criticality is reduced since the neutrons generated from spent nuclear fuel are absorbed. Also, immediate neutron absorbing power is provided upon refilling the pool water into the spent nuclear fuel storage pool in which pool water is depleted.
