The present invention relates to an optical fiber probe for measuring the pH level in a nuclear reactor cooling system and a pH measuring system using same, and more particularly, to an optical fiber probe for measuring the pH level in a nuclear reactor cooling system and a pH measuring system using same, which, by encircling the outer circumferential surface of the optical fiber that is inserted into a fluid channel with a protective tube, forming a waterproof film at the end portion of the optical fiber which is exposed from the protective tube, and by being equipped with a porous pH reactive film, which is formed by means of a sol-gel method, on the surface of the waterproof film, the degradation of the optical fiber due to direct contact with a high-temperature, high-pressure fluid can be prevented, and at the same time, the degradation of a pH reactive substance can be effectively prevented by impregnating the porous pH reactive film that is formed by means of the sol-gel method with ...
