    Abstract: The long-lived fission products(LLFPs) are critical nuclides for geological disposal and partitioningtransmutation of highlevel waste. The paper reviews the measurement, present status and the progress of fission products nuclear data, such as half-life, fission yield and thermal neutron cross section for 13 longlived fission products with the half-life of more than 10 a and fission yields of more than 0.01%. The radiochemical separation and purification, measurements of atom number and radioactivity of the long-lived nuclides in the field of measurement of fission products nuclear data are discussed and some interesting ideas are pointed out.
