Creation of 200 MW compact safe energetic installation on a base of a high-temperature, gas-cooled, subcritical reactor was discussed in paper [1]. Chain reaction was initiated by the outer neutron flow. It was proposed to obtain such a source by irradiation of different substances with an intensive proton beam from the linac. Now possibilities of such a scheme are considered in more details. Structure of the reactor active zone is discussed. The use of the cyclotron as a driver is considered as an alternative variant. Problems of reliability, radiation safety and cost of installation are taken into account too.
