It is absolutely clear from all the high-level reviews that have been undertaken that there is no doubt about the validity of the technology itself. The main feature of the PBMR, as I have said, is that its safety features are inherent in the physics of the design. This is as opposed to the add-on engineered safety features, as are found in current light water reactor nuclear plants. In the original PBMR design, the system is a so-called direct-cycle system where the reactor coolant, which is helium in our case, passes through the turbo generator plant without an intermediate system such as a boiler. This arrangement promised greater thermal efficiency and safety, hence its attractiveness as a future nuclear generation technology.
