Results from ISTC frame work

Under International Science Research Center (ISTC) projects, JAERI Nuclear Data Center has been taking a role of collaborator and monitor for following items; 1) Measurement of the Fission Neutron Spectra of the Minor Actinides and Spontaneous Fission of Curium Isotopes (ISTC no. 183: V.I. Khlopin Radium Institute, KRI, St. Petersburg, Russia), 2) Measurement and Analysis of the Basic Nuclear Data for Minor Actinides (ISTC no. 304: Institute of Physics and Power Engineering, IPPE, Obninsk, Russia), and Evaluation of Actinide Nuclear Data (ISTC no. CIS-3: Radiation Physics and Chemistry Problems Institute, RPCPI, Minsk, Belarus). These are related to the Japanese OMEGA Project and expected to supply minor actinide (MA) nuclear data, since Russia has good quality MA samples, experimental technique and nuclear data evaluation experiences. In this report, out-line and some results of above three projects are reviewed. (author)
