Studies relating to central nuclear heat supply systems in the United States

Since approximately 40% of primary energy consumed in the USA is for applications requiring thermal energy at below 2000C, this application of nuclear energy is receiving increased ERDA attention. Status of programme is presented including review of ERDA-sponsored projects relative to utilization of waste heat from nuclear electric power stations for agricultural and aquacultural purposes. Presentation covers ERDA plans in support of introduction and siting of small nuclear plants for industrial/commercial energy, as well as plans for fostering introduction of large dual-purpose light water reactors (LWRs) for electricity and steam generation. Also mentioned is an intended study of a specific nuclear steam grid system which would serve both industrial and district heat demands and would evaluate potential for retrofitting existing installations within this system.
