The present invention relates to a fiber-reinforced concrete composition for a containment building of a nuclear power plant. More particularly, the present invention relates to a fiber-reinforced concrete composition for a containment building, said composition improving both the toughness and shock resistance of the containment building of the nuclear power plant due to the chemical and physical properties of the fiber-reinforced material, thus ensuring stability against external shocks (caused by large civil aircraft, light aircraft, combat aircraft, or the like).
