Process Heat and Cogeneration Plants

Several of the proposed designs are explicitly stated to be usable for process heat generation in single purpose plants, notably the GEC/UK Magnox plant, the BBC/HRB and the Interatom high—temperature reactors, although others could also be used in this manner. 

Several suppliers have stated that dual-purpose applications, such as in desalting plants are foreseen (Rolls Royce PWR 300, HRB 100-500 and Atomenergoexport VVER-440). It is not proposed to obtain an optimized design through a back pressure turbine but simply to bleed off high-pressure steam at the high pressure turbine. This is in itself a proven and simple method. 

For the VVER-440 plant, the supplier quote economical dual-purpose applications in the areas of district heating, seawater desalting and industrial processes. 

One supplier estimates that there may be a potential market for about 48 cogeneration modules of HTR for the Federal Republic of Germany s internal market. In China there are preliminary feasibility studies under way for district heating in North-East China and also for a dual purpose nuclear power plant for the Shanghai Petrochemical Complex. 

SMPR for these applications would be less sophisticated than for the electricity generating reactors. Countries having industrial
