An isotope dilution mass spectrometric method (IDMS) has been used for the determination of caesium, neodymium, uranium and plutonium isotopes in pressurized water reactor (PWR) spent nuclear fuels irradiated in a power reactor. The method includes the determination of Cs, Nd, U, Pu and their isotopes through thermal ionization isotope dilution mass spectrometric by using quadrupole spikes ( 133 Cs, 150 Nd, 233 U and 242 Pu). The measured atoms of the radioactive Cs isotopes ( 134 Cs, 135 Cs
