In the newly approved Joint Research Project for Regional Intensive in Iwate; `Development of practical application of magnetic field technology for use in the region and in everyday living', application of magnetic field environments realized by high TC bulk superconductors is one of the main R & D subjects. Numerical analyses on scattering mechanisms in the thermal conductivity of (Nd,Eu,Gd)Ba2Cu3Oy[NEG(123)] bulk superconductors with 10, 20, 30 mol% NEG(211) second phase (SP) were performed. We found a strong correlation between amount of added second phase and scatterings by grain boundary and Umklapp process. Performance of power leads made of [NEG(123)+30 mol% SP] bulk superconductor for strong stray magnetic field environment was also estimated.
