The Polish Government decision to include nuclear energy option in a number of Poland's future energy solutions challenge the specialists with a question of choosing of a nuclear reactor, which fulfills the conditions ranging from technical to social issues. Contemporary nuclear reactors are used to produce electricity only, however, some reactors belonging to so-called IV generation can be as well employed directly by the industry. Two features of these reactors are decisive: 1) relatively low heat power - no more than few hundreds megawatts, 2) high temperature of the helium coolant of about 900 oC. Nuclear process heat at such a high temperature can be utilized, among other applications, for coal technology, for production of hydrogen used in many industrial processes. Hot helium can also be applied to obtain many carbon-based valuable products. High temperature helium-cooled reactors, play more roles than classical high-power reactors. It seems to be an attractive perspective for Polish economy which is now so much dependent on imported oil and gas, but keeps a high potential in coal industry. CO2 from the coal power plant recycling into synfuel with the use of hydrogen from a water splitting factory driven by nuclear process heat from the high temperature nuclear reactor is one of the challenging ideas.
