Abstract: The study deals with the possibilities of district heat supply using the realistic example of the KRB Gundremmingen boiling-water reactor. In its final construction this nuclear power plant is layed out to produce a total power output of 2870 MW$_{gross}$ with comprising blocks A, Band C; block A of a capacity of 250 MW has been operating since 1967. The area to be supplied is located in the Federal State of Bavaria, situated to the right and left of the Danube river, and comprises the districts of Dillingen and Günzburg. It involves 8 placesi the total number of population amounts to 55,000. Maximum straight-line distances from the nuclear power station are around 10 km in north-east direction, and around 15 km in southwest direction. The following was made use of to calculate the heat demand for the area considered:a statistical questionnaire to determine the annual heat consumption and the connection data for residential buildings, official buildings, commercial buildings and industrial plants to be filled in by the various communities; town-maps; the Bavarian Municipal Statistics of 1970 with the results of a building and dwelling census taken on October 25, 1968, results of a non-agricultural workplace census taken on May 27, 1970, and results of a population census taken on May 27, 1970, as weil as a final local inspection. The results show that some places indicate characters that are in favour of district heat supply. However, the heat price is adversely affected by the narrow road configuration in the ancient town centers, the low consumption of heat resulting from the small number of inhabitants, as weil as the large distances from the power station. The advanced projection of blocks B and C does no longer permit a thermodynamically meaningful extraction of heat from the power station, so that the advantage of cheap nuclear heat thus is partly lost again. Added to this is the fact that, due to the activity in the direct-cycle unit of the boilingwater reactor, the heat exchangers for district heat extraction fall into the controlled area, thus eventually impeding the licensing procedure. According to the calculations and estimated carried out, the heat price for residential heating expected at present are above those of individual central heating plants.
