The paper proposes a low aspect ratio tokamak for the driver of a transmutation reactor. The main parameters of the reactor core and a neutronic analysis of the blanket are given. The previous analysis showed that the neutron wall loading can be lowered to the order of 1 MW/m~2 for an adequate trans-mutation capacity and efficiency. The recent analysis confirms this conclusion. The neutron wall loading could be lowered even further to the order of 0.5 MW/m~2, which could easily be reached in the near future. It is also shown that the transmutation efficiency (fission/absorption ratio) is higher than in the previous analysis. The blanket power density is about 200 MW/m~3, which is not difficult to deal with. The key components of a low aspect ratio transmutation reactor, such as the divertor and the centre conducting post, are also analysed and compared with those of a conventional tokamak. Finally, a comparison is made with other drivers such as fast breeder reactors, pressurized water reactors and acclerators. The low aspect ratio transmutation reactor is one of the applications of fusion energy that could be realized in the near future.
