Low-Activation Reinforced Concrete Design Methodology (5) - Low-Activation Material Development Support System-

摘要

Radiation shielding wall and biological shielding wall in a typical light water reactor become low-level radioactive wastes by thermal neutron irradiation after reactor decommissioning. Since volume of the concrete waste after reactor decommissioning is very large, to control the radioactivity level of the material below clearance level leads to reduce remarkably the amount of radioactive waste of the nuclear plant. It will contribute to safety of reactor disassemble work and reduce disposal cost of radioactive waste. Raw material selection of steel reinforced concrete is considered to be the possible key to solve this issue. To show the guideline for the low-activation design, low-activation material development support system (LAMDS) was prepared.
