As in other modular HTGR, this ordered bed was also designed
to ensure passive decay heat removal without radioactive material
releases in the case of an accident. In addition to the unique high
level of reactor safety, the ordered bed was found to possess great
structural flexibility and stability because the spheres in the
ordered bed moved in a spring-like fashion. The flexibility and stability
permitted the bed to compensate for thermal and pneumatics
fluctuations and withstand pressure from different direction
