THE MARKET POTENTIAL OF MODULAR HIGH TEMPERATURE REACTORS AS COMBINED HEAT AND POWER PLANTS IN THE FEDERAL REPUBLIC OF GERMANY
The High Temperature Reactor (HTR) Module is a small pebble bed reactor. In a secondary steam circuit electricity is produced and heat recovered in the temperature range up to ca. 350 degrees C. In combined heat and power (CHP) operation the heat can be supplied to district heating systems (<180 degrees C) or as steam to low temperature (<350 degrees C) industrial processes. The modular reactor units can be combined to larger stations, here, the standard design is for a 2 x 200 MW CHP plant with ca. 135 MW electric and ca. 250 MJ/s heat output. The final energy demand is in future in the FRG not expected to change significantly from today's level. The recently published PROGNOS study has been chosen as the starting point for the scenarios of this study with a time horizon of 2020. In the economic evaluation of CHP plants with start-up 1993 the 400 MW HTR Module is found to be economically competitive with a similarly sized coal fired station. Of the requirements for replacements and additional capacity only a fraction is technically suited to accommodate a 400 MW HTR Module plant. These are district heating systems and industries where large units already are in operation or expansions are expected. The cumulative technical potential for both areas of deployment is calculated to 37.000 MW for the whole period up to 2020 of which some 17.000 MW will be required before 1993. The market potential is inevitably smaller than the economic potential and is not accessible instantaneously. The introduction phase of HTR Modules was assumed to last between 15 and 20 years and approach a market share of new orders of 50%, i.e. half of the economic potential available in any year is allocated to the HTR. Starting with one, pessimistically and three, optimistically, demonstration plants in 1991 - 1995 the cumulative installations reach some 10 to 12 stations by the end of the study period in 2020. The estimated market share for the HTR Module assumes that the environmental advantages are realized and accepted by the public. It also presupposes a good operating record of the demonstration plants. The at present envisaged economic competitiveness will have to be manifested in the future market.
