Abstract:
The long-lived fission products(LLFPs) are critical nuclides for geological disposal and partitioningtransmutation of highlevel 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 longlived 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.
